Re: GQ Aircon evaporator

Jules,
Praat met Enzo by Global Nissan Silverton.0128048166.
Hy ken die patrols goed en dit help dat sy broer in die fabriek werk.
Ek het ongelukkig nie meer die part nommer nie , maar ek het myne by Enzo gekry.
As hy weet jy is deel van die forum gee hy ook gawe afslag.

Groete

Re: GQ spitting some white smoke startup

Jules,
Daar is n paar ander moontlike redes ook vir die dampies.

Geblokte "breather" of foutiewe kleppies in die "breather" pyp sisteem sal olie in die inlaat spruitstuk laat opdam en dan brand as die enjin aansit.
Kyk vir tekens van baie olie in die lug inlaat pyp waar die blok ventileer pype inkom. Kyk ook vir "blow by" druk in die enjin deur die olie prop af te haal as hy luier. Daar behoort min lug daar uit te blaas.

As daar fout is met die "needle and seat" sal daar ook oortollige petrol in die spruitstuk le wat dan n rookie sal veroorsaak. (Vra vir Piet)

Daar kan ook remvloeistof deur die vacuum servo lek en deur die inlaat gesuig word. As remvloeistof verdwyn is dit die fout.

N kompressie toets sal bevestig of die fout by die ringe le.

As jy die enjin gebruik om te rem op n lang afdraende en dan rook sien wanneer jy weer versnel , is dit heel moontlik klepskag seels.

Sterkte.

Hubs Auto changed to manual.

The automatic/manual hubs on my old 4.2 finally decided to retire after close to 500k km. One of the many parts inside this complicated unit broke.
The previous manual hubs I got from Commercial auto parts in Selby JHB for one of my Safaries looked cheap and of inferior quality , but to date has not failed.
I did not want to fit inferior components to a strong vehicle , but any part is better than no part , so I purchased a set from Commercial and fitted them.
The units I got was much better than the older ones and also fitted perfectly. They look exactly like the original Nissan manual units.(possibly a cheap but good copy)
They work and now only time will tell if they will last. It is also much less complicated.

It cost R1350 per set and were for 31 spline axles. There are still some in stock. I also saw auto/manual units there for the same price. They also have 27 spline units in stock.

Re: Fuel supply failure

Josh,
The use of an aftermarket pre filter is common practice for most trucking operators that go long distance is Africa.
The type I use is a very simple unit consisting of a mount housing with the feed pipe connected at each side and a canister screw on filter/water trap.
They are designed to remove the worst impurities and prolong the life of the o e filter. It is a Cummins approved system and the filter canisters are readily available.
I have towed many diesel vehicles with terminal engine failures due to water in the fuel back to base in the "undeveloped" countries north of us.
The most spectacular was a Puma Land rover. The engine pre ignited when shut off and over revved in reverse burning sump oil to termination. Eina!

The filter to use is a Fleetguard SF1212 with the correct mount.

Re: Fuel supply failure

These pictures show them the best. Here it is fitted to a 80kva Volvo Penta generator set.
This engine runs very clean and conforms to European emission standards. This engine has done about 500 hours with this setup fitted. (obviously I change the cartridge at each service - 200 hours)

It would be best to consult the sales people at cummins to get the best filter option that will be compatible with the application.
With petrol vehicles , water removal is a problem as the properties of petrol and water are similar and the filter will let some water through and these filters are primarily designed for diesel.

Re: Interesting Read - Patrol bakkie vs Landcruiser

Kom nounet terug van Rwanda waar ek die hele week met n Cruiser bakkie moes werk. 4l v6.

Ek dink ek gaan nog n week mank loop en my niere sal seker weer volgende week begin werk.

En as jy meer as twee grawe en n pik agter op laai skyn die ligte teen die boomtoppe vas.

Toe ek gister aand by die huis kom het ek eerste my bakkies gaan groet en toe my vrou. Dit sê alles.

Re: Air cleaner for 4.2TD

I have 2 photos of the installation. Some breather pipes were not connected yet.

I use Donaldson type aircleaners because dirt is not welcome in any engine. Never. Performance might suffer but the engine will last.

This is on the gq with the transplant tb45e engine.
I used the thumbsuck selection method and used a 90mm outlet standard Donaldson cyclone air cleaner. It just fits in under the bonnet and I custom built the bracket for mounting onto the wheel well. The only drawback is that I have to loosen the mount clamps to get to the cartridge for cleaning.

The positioning made for minimal bends and virtually straight pipes in and out. The air gets sucked in from the original hole in the fender , so water does not easily gets in there. Also , the big inlet pipe is at an angle and with low engine speed , water will most likely not get drawn in. On this type , all the air is drawn in at the inlet pipe , so snorkel will work.

The change in pipe configuration played havoc with the engine management. I used the same air mass sensor housing and sensor , but the air flow patterns made no sense to the sensor.
Two hours of remapping by Maus and all was well again.

Those filters are used by most big engines. Look at the big generator sets and air compressors as well as most industrial earthmoving machines.

Re: GQ Fuel gauge not lekker

Oom Mack , As dit n earth problem was sou dit nie net tussen kwart en leeg pla nie.

Die tenk sensor bestaan uit n reostaat wat met n arm gekoppel aan n dryfballetjie die vlak meet.

Daar is n stuk weerstand draad opgewen om n nie geleidende basis. die een kant van die draad is ge aard en die ander kant is oop.
Die bewegende kontak punt skuif op en af soos die tenk vlak beweeg. Hoe verder die kontak van die aard kant af raak , hoe groter die weerstand. Die instrument by die meters gebuik dan n bimetal strokie on die wystertjie te laat beweeg.

Jules. wat gebeur is dat die bewegende kontak nie meer behoorlik raak aan die weerstand draad as die tenk leeg word nie.
Die tenk sensor kry jy onder die mat agter in die laai area binne in die tenk.

Jy moet die armpie uithaal en effens buig om weer goed kontak te maak. Partykeer is die draadjie ook af.

Wees baie seker dat al die aard drade weer baie goed terug gesit word en moenie n vuurhoutjie trek om gou te kyk hoeveel vuilgoed daar in die tenk le nie.
Altwee sal dieselfde resultaat he.

Re: Trouble in Botswana

Barry
Those tie rod arms are very strong on the patrols and will only fail under extreme conditions.
In your case I suspect the heating when trying to loosen the nut , damaged the metal and most probably was not fastened properly afterwards.
When loose , it would rattle until the thread is no more. I would go and have a chat to the people responsible.

Generally , welding on any critical component is not permitted and renders the component unusable. In this case , it was an emergency.
The female end is cast iron and the lock nut is steel. Not compatible with normal arc welding. That will explain the "hoenderkak" welding. It would not be something I would trust my life on.

I trust you have replaced the whole tie rod.

Regards,

Chris.

How deep is At Se GaT ?

I have young Alex and my daughter visiting from the Cape and he brought his lifted 4.5 and a lot of enthusiasm.

At the first sign of rain , we are off to the local quarry and play like small children. Patrols are too good for the obstacles and we return victorious.

Next day we go to At se Gat to see if we can unsettle these beasts. ....Little did we know.

First onto the mountain. It is already tricky because of all the rain. He tries the z turn first without success. I tell him that I will reverse the first steep part and then go forward over the second bit. Then I will be on top to pull him up if he gets into trouble. I reverse up without too much effort , but park too closely against a rock with back bumper...eina. Then easy forward movement up the z...noooo. I slide into an akward angle that leaves two wheels in the air and me going nowhere. Had to use my winch just to get the car straight enough to safely reverse down,tail between the legs. STRIKE 1.

We take the landrover friendly route up the mountain and find nothing else to beat the two wounded beasts. Lots of fun trying the difficult routes a few times.

It is getting close to beer time and we decide to take a quick easy detour along the muddy river edge to at least put some telltale mud on the cars.
The river is very high and the mud is all hidden with lush green vegetation. I tell Alex that we must keep at least one car unstuck for recovery.
We both have 33 muds on and his car is lifted very high. Wheels at one bar and face it: These are Patrols! we can not get stuck.

I go in front and choose a safe easy route with some unexpected deep holes hidden in the grass. Very wet with standing water everywhere. It is the easy marked track and should pose no problem.
One or two hairy moments but I get through.
And then one catches me and I have to "pause momentarily" and look back to see if Alex can help with a towstrap. All I see is his vehicle growing shorter in the mud bog 20 meters behind me. Another temporary pause. SH!t and curses. Two cars immobile and cold beer waiting in the bar. STRIKE 2 and 3.
Out comes the winch again and true to form starts acting up and working erratically. A loose wire in the control relay box. I get unpaused and then attend to the quick and easy recovery of the other now very low slung Patrol. I do not like kinetic straps and use the normal strap. It is like pulling against a granite mountain. No traction on the wet cotton soil and the other car has both diffs below ground level in the mud.
Some high lift jack exercise and rock carrying mixed with spicy language , and the self confidence returns.

After improving our confidence some more in the pub , we head home only to find out that the auto box in my car now only had 2 gears. First and second. Maybe third fell into that mud bog.
That car can drive at 120 in second and it can go like that for 100 kms. Next morning we wash them with power washer and drive to the shop. The gearbox is back to normal and shifts like always.

Two things saved our bacon. We had a good combination of equipment and kept calm and applied the basics including safety rules.

Be Aware: That gat can bite back.

Re: Auto locking hubs.......HELP Please!!!!!

My suggestion is to change those auto hubs to the manual ones at the first sign of trouble.

I have had endless trouble and malfunctioning front diff issues. Tried to repair it a few times and eventually just bought the manual replacements.
The units I bought from Commercial auto are still working perfectly.

When doing the more extreme trails , it is a lot safer to know your machine is working properly!

Re: 1984 Safari 2.8 Modifikasie na 4.2 petrol

Stem saam met die kommentaar hierbo.
Die grootste probleem is die ewenaar aspek wat n baie sterk 100km/h teen die 4.2 se maksimum toere sal gee.

Het nounet een van my Safari 2.8 masjiene volledig laat oorbou met boor , suiers , kleppe als nuut vir R15000.00. En hy loop soos n horlosie.

Verbeteringe op die 2.8 wat werk is :Effens warmer nokas met n 38 Weber vergasser en elekrtoniese vonkverdeler. N branch uitlaatpyp werk ook goed op die enjins.

N ander opsie is Nissan se RD28 diesel enjin , maar dan het jy n donkie.

Re: Wat staan my te doen??

Johan,
Self doen is maklik.Draai die enjin todat die nok by die klep wat pla die verste weg van die "follower" is.
Draai dan die verstel skroef (14 en 17 sleutels) heeltemaal in. M a w tot by grootste gaping.
Maak seker dat die kontak area van die "follower" en "valve stem cap" asook die nok nie beskadig is nie.
Sit dan alles reg terug en stel die toleransie. Kyk sommer na al die ander kleppe sn ook.
Daar is baie maniere om die enjin te draai en kleppe te stel , maar my finnige manier is:
Wanneer die twee nokke van n silinder oorskakel van uitlaatklep na inlaatklep "rock " die kleppe.
Op die enjin werk 1 en 6 saam , 2 en 5 saam en 3 en 4 saam.
Wanneer 6 rock , stel 1. wanneer 1 rock , stel 6. dieselfde met 2/5 en 3/4.
Maak seker dat die twee nokke wat jy stel aan die teenoorgestelde kant van die nok is as jy dit stel.

Thinus,
2 stroke gaan nie werk nie.
Meeste vulstasies verskaf Valve Ease as n bymiddel wanneer hulle nie LRP het nie.

Re: River trip 6 tot 10 aug 2015

I filled up in Tzaneen and had to add 40l at the end of Molototsi. That much fun can not be bought for ten times more.
The consumption could be good because I was at the front doing Recce and made the first tracks in virgin sand. (and I packed light)

Got recovered once by Dirk from a mud bog :redface: but that happens when you make the first tracks.

I had the privilege to do the "higher grade" section in Klein Letaba with Thinus , Micael and Alex. It can be described as 500m of grade 4 and very tough.
Thanks to those who waited and encouraged us through there.
The GQ never missed a beat and is home in the same condition it left.

Re: Safari with Autobox

As jy regtig groot wil gaan , is die ultimate om n Gq oordra ratkas te vat en die l28 autobox se extension af te haal en dan die twee aanmekaar te bout. Met heelwat modifikasies natuurlik. Dan is jy ontslae van die kort propshaft wat altyd vibreer en sit met n onbreekbare oordra ratkas. Die cross members kan rondskuif en die voor en agter propshafts kom op die regte plekke uit. Handbriek drom is ook dieselfde plek as die ou een. Sal dalk die shafts effens moet verander. Ons het al die somme gemaak , en die ratios werk perfek uit.

Re: torque converter behaviour

A torque converter with auto box does the work of a clutch with a manual box.
At idle , the converter freewheels and thus allows the engine to turn with the gearbox stationary.
When power is applied , engine revs are converted to torque and the gearbox starts turning.
As speed increases , the gearbox will upshift and the converter will accommodate the difference in engine rpm and gearbox input rpm.

If fitted , the lockup function will only engage when a steady speed with steady engine power is applied. I think that the 4.8 tiptronic box will also engage lockup in 4x4 under certain conditions to aid with engine braking.

A converter allows you to apply very high torque to the wheels at very low wheel rpm with more control than with a manual clutch.

The rise in engine rpm you ask about is an exchange of rpm for torque and as the power/load ratio changes , the difference between drive and driven shafts will change. (within limits and including component losses)

Re: Safe to drive with this..?

Fanus,
Ons het daardie selfde groen 4.5 wat jy in Sabie gesien het se koppelaar en vliegwiel vervang in Januarie.
Ek het die parte in voorraad gehad en Autobox in Koedoespoort Pretoria het vir ons die ratkas uitgehaal , parte vervang en weer terug inmekaar gesit.
Dit is dieselfde operasie wat jy nou gaan doen. Al verskil is dat die seel agter die vliegwiel vervang word. (Sal dalk goed wees om dieselfde tyd te kyk hoe die koppelaar lyk en te vervang.)

Ek is n gereelde klient by Autobox en hulle behandel my altyd goed. Die arbeid total was R2500. Dit is baie billik vir die hoeveelheid werk.

Dit behoort vir jou n idee te gee wat n markverwante arbeid behoort te wees.

Good service at Viper and SAC Boksburg

An old leaking manifold gave me an excuse to get a branch for my 4.5.

Abel at Viper did a great job as usual and the ceramic coating inside and out has made a big difference in under bonnet heat.(It also sounds great)

After fitting the branch I quickly visited SAC in boksburg for a dyno run. It needed some tweaking and after 40 minutes I was going home with a smile.
Definite increase in torque and power. Will see what the consumption does.

While I was there , Leon mentioned that he has a friend overseas that has a very nice 4.5 Gu for sale that is in lockup in Johannesburg.
I remember he mentioned R120k and that the vehicle is in very good nick. Contact Leon at Steves auto clinic in Boksburg.

Re: Patrol Spotting

So I am busy with work in Jefreysbay and was killing time at the beach when I see a fairly big boat beach.
Expected a big tractor to come and load it , but no. A 4.2 Patrol pickup with marie biscuit wheels pumped to 3 bar arrives.
And there was no trouble. Heard one of the locals say "Dis darem n demm sterk bakkie daai!"

Re: Fuel consumption

It depends on a couple of factors.

Standard with no load and steady 110 to 120km/h it should be 5 to 6km/l

I have three of them fitted with 38 Weber and branch and hot cam. They can do up to 7km/l but the sound and power causes a heavy foot and it is always 5km/l. Two of them has 1.5 ton rigs bolted on and it can go as bad as 4.5km/l.

My early 84 model indicates 140km/h when the gps shows 120. The later models show 130km/h at a true 120.
All of them has 12.5x33x15 tyres.
