Re: Fredlin Hoist

I hope this helps. Shout if you require better photos of a specific area...

The rear area is simple - it consists of a roller on each side containing a single run of the webbing. This webbing runs inside the U-channel of the hoist to the front part, where it is fitted to a dedicated roller on each side.
Agter.jpg

The front part is a bit more complex. You'll end up with two rollers on each side. One roller lives inside the other end of the U-channel and guides the webbing that comes from the rear of the hoist. The other roller lives inside the top part of the fancy 45-degree bracket and handles the webbing for the front part of the hoist. The 45-degree bracket is bolted onto the inside of the U-channel. You'll have a similar setup on either side of the hoist to handle the front and rear of the webbing:
Voor links binne bo.jpg

The bottom part of the 45-degree bracket contains the shaft that actually performs the lifting. You'll fit the rear and front webbing onto this shaft, and repeat it for the left & right sides of the hoist. The webbing going to the rear roller is obviously much longer than the webbing that goes to the front:
Voor links onder buite.jpg

A shaft connects the bottom of the two 45-degree brackets together so that both sides are lifted by the same amount when you crank the handle of the worm gear.

I found it easiest to construct it on the ground first. I took my measures like that, then I welded some flat bar to the underside of my roof, drilled holes where required (the U-channel of the hoist is pre-drilled at appropriate points) and bolted the hoist onto the flat bar.

Re: 4x4 Regulation

This implies that every time someone goes to a new area (even if they've been there before) they have to do another course and exam. If it is implemented as a quick questionnaire before entering the area, then I'm happy. But if this is going to be one of those: make an appointment two weeks in advance, spend three days doing a course and then a written exam, then not cool. I have no interest in driving down to an area two weeks prior to my trip to sort out licensing, then have to struggle with bad service, all just so I can spend one long weekend camping for instance....

Wilhelm, I also think you're worrying unnecessarily. Here's what I know at present...

There are two unit standards that are applicable to off-road driving - Unit Standard 254135 ("Apply the techniques for operating four wheel drive (4WD) vehicles, in on-road and off-road conditions") and Unit Standard 254154 ("Apply advanced techniques for operating four wheel drive (4WD) vehicles in off-road conditions").
The unit standards have been ratified by the South African Qualifications Agency (SAQA) and can be downloaded from their web site.
You'll only require the former for your driver's competency certificate (the so-called "DCC"). The latter may be done for your own pleasure, or if you are pursuing a professional driving qualification that requires you to gain additional credits. The latter does not require a practical exam.
Both of these unit standards state that the last date for their achievement is 2015-11-26. This may be extended, or the unit standard may be replaced with a new one. Nobody knows yet - we've never been down this road before.
If the unit standard changes, they may require you to renew your DCC. Yet again we do not know, because we've not lived through a change of the standard yet.
There will only be one DCC, and it will be valid for each & every trail that is ear-marked as "sensitive". If the trail is not marked as "sensitive", you will not need a DCC to drive it.
We should not be upset with "them" or "they". These unit standards were developed by off-roaders for off-roaders as a means of self-regulating before government deemed it necessary to step in & do their own brand of regulation of a fraternity that was often criticised by outsiders. The guys are looking for assistance to take the process forward - a golden opportunity for anybody to get involved and help the process along from the inside.

The above is what I can recall after attending the training last year. Some of this may have changed since then, but that's the gist of it...

Re: 4x4 Regulation

Here's a link to the two unit standards:

Unit Standard 254135 ("Apply the techniques for operating four wheel drive (4WD) vehicles, in on-road and off-road conditions")

Unit Standard 254154 ("Apply advanced techniques for operating four wheel drive (4WD) vehicles in off-road conditions")

And I see that the last date for achievement has now been extended to 2019-06-30...

Re: Diff locks

If there is a problem, the chances are 85% that it is a vacuum problem. This is relatively easy to sort out. Some guys strip and overhaul the solenoid, some replace them with far more robust industrial solenoids. Just don't ask Nissan to fix it for you.

Most of the last 15% is that the electrical switch on the rear diff that tells the system when engagement has occurred is faulty.

And if you do not fix it quickly, you'll end up with worn bits & pieces resulting in a HUGE repair bill...

Re: replacement bumpers for nissan patrol for sale

Peter slaan die spyker op sy kop!

My Patrol het 'n lugsaksensor binne-in die stuurwiel, mooi agter die lugsak en reg bokant die moer wat die stuurwiel in plek hou. Dit is 'n swaar metaal gedoente wat weerskante op sagte rubber gemonteer is sodat hy kan vorentoe & agtertoe beweeg. Stamp jy iets net 'n fraksie te hard (in 'n reguit lyn, natuurlik!), beweeg daai ding vorentoe, voltooi 'n elektrise kring en POEF!! sit jy tot agter jou ore in lugsak....

Vir 'n yster bumper om "airbag compatible" te wees moet hy van plastic gemaak wees, of rubber monterings hê :mytwocents:

Re: Third Row Seats - Free to Good Home

Slangaman -- you stil in Grassfontein?
You think maybe the new Patrol seats will fit into LOBO ?? If they can fit I will appear with a case of said C*&*&^$# Lager [un diluted, full strengt or the "light" sissi stuff ?? :lol: ]

Oompie, ek's nog steeds hier in Garsfontein - te lui & te arm om te trek.

Daai sitplekke skroef sommer net aan twee gate onder op die vloer vas. Dit help natuurlik as die gate bietjie van die grond af gelig kan word, anders sit mens erg ongemaklik met jou bene so reguit voor jou uitgestrek. Terloops, daar staan nog 'n sleepstang ook hier rond met wat dalk onder aan Lobo kan vasbout. Ek vermoed die ladder frame chassis van die verskillende Patrolle sal dalk minder of meer, ongeveer dieselfde wees?

PS: As die Tafels onverkrygbaar is daar in die "verre ooste" drink ek & my Yvette graag Windhoek Lagers ook! QQQ

Re: Which VHF Radio

Is there another place one can put the antenna so that I can actually talk to the bloke 10 km in front of me? :confused:
The problem with the roof rack may be trees and branches (powerlines?) and what about when the roof rack is off?

Go for the shorter type 1/4 wave-length antenna and mount it just ahead of your windscreen. They're short enough to leave in place permanently, since they do not extend above your roof. They do lose out in total transmission strength ("gain") compared to the longer 5/8 wave antennas, but they work better in hilly areas as a result of their wider radiation pattern. Due to the more centralised location on your vehicle you will transmit a bit better all around your vehicle. Your Patrol will also look more symmetrical, since you'll have an antenna of similar length on both sides :biggrin:

Can one get hand held VHFs that are more than 5W? (then I can just send SWAMBO up onto the roof rack :lol: ).

Dunno for sure, but I seriously doubt it. That small battery just won't handle the currents involved with large transmission power, and if you were to accidentally touch the antenna whilst transmitting at high power you'll know all about it :shocked:

Re: Electrical fans

On mine the two wires have broken off so the fan runs constantly when I switch on the AC.

Cedric, it's meant to do that! But fix those broken wires any way - the Maiden will thank you for it!

There are two sender units at the bottom of the 4.2 diesel Patrol's radiator. One of them (the LH one, if i remember correctly) is a temperature cut-out switch that disables the AC compressor when the coolant temperature exceeds a certain temperature (about 110 deg C). The other one is the engine coolant temperature switch mentioned below.

Cooling fan.png

If you look at the drawing it becomes clear that the AC fan will turn on when either of the following is true:
The coolant temperature exceeds 96 deg C.
The aircon switch is turned on.

What's not so easy to see on the picture (they really need better graphic blokes to compile their service manuals!), is that the fan will also turn off at higher speeds (>70 km/h) as long as the motor remains cool. If the coolant temps increase, the fan will still turn on.

I'm not sure how the second fan gets activated on the petrol models. Us diesel owners have to make do with only one...

Re: DYNO day 30 MEI 2015

Chuck did 119 kW (3200 rpm) and 380 Nm (2200 rpm). Some of the other 4.2 diesels (ja, Andre, ek kyk na jou!) kicked serious dust (smoke?) in our eyes, though :biggrin:

The Z managed a 355 kW (6000 rpm) and 560 Nm (4250 rpm) run later in the day. See why petrol cars also need turbos? :thumbup:

Re: Madman / Landy on line

My opinie is dat 1 bar heeltemal OK is op 'n diesel motor. Of dit hoog of laag is vit jou turbo sal jy kan uitvind deur Mnr. Google te vra.

Onthou dat diesels dikwels tot twee maal die kompressieverhoudings van 'n petrol engine het, dus is die con-rods, blok etc. daarvoor ontwerp. Ons outydse 4.2 motors loop teen iets oor die 22:1 kompressieverhouding!

EGT wat hoog is reflekteer meestal op diesels hoeveel van jou brandstof nie verbrand nie. Die mees algemene oorsaak van onverbrande diesel is te veel diesel, maar te min lug om dit te verbrand - sogenaamde "overfueling". Nog 'n maklike simptoom van over fueling is swart rook uit die skezors as die motor hard werk. Die ouens op die "Oz forum" skryf gereeld meer boost voor as 'n manier om jou EGTs laer te kry, en dit werk presies net so in die praktyk.

Chuck loop ook op 1 bar se boost. Sy EGT is lekker laag (so vlak 600 teen woeste bulte uit) omdat sy fueling mooi aangepas is vir die hoeveelheid boost.

Terloops - nog redes vir EGTs wat hoog raak is slegte injector sproeipatrone (dan ontbrand die diesel te stadig), verkeerde timing (as die ontsteking te laat plaasvind, is van die diesel nog besig om te ontbrand terwyl dit by die uitlaatkleppe uitgaan), verkeerde "crack pressure" op die injectors, ens. ens.

Re: Turbo charging a TD42 engine

You'll also be fine without the boost compensator (an "aneroid" really sounds like something you should be taking pills for!)...

The problem when tuning the engine without an android is that the diesel pump won't increase it's delivery according to the boost level (which is what you want), so you have to optimise the pump delivery for either on-boost or off-boost. Obviously you'll adjust it for on-boost fueling, which means that the pump will supply too much fuel when the turbo is off-boost. That causes momentary over-fueling, resulting in some smoke when pulling away briskly.

Because the puff of smoke is always behind me (unless I storm off in reverse gear!) and it only happens for a brief moment, I am very happy to save the money I would have spent on an android and rather spend it on nice set of tires, a fridge/freezer, or something for my wife (how did this end at the back of the sentence?). As you may have guessed by now my TD42 does not have a hemorrhoid...

PS: This is a problem that only afflicts the old TD42 engines. The later engines had an ECU that controlled the fuel delivery based on air-flow, accelerator pedal position, engine temperature, phase of the moon, etc. It also took all the fun out of endlessly fussing with the fuel screw on the diesel pump :lol:

PPS: Inter-coolers cool the turbo-charged air down, allowing for higher boost than without them (yes, please!), and for increased engine life (cold air is less likely to result in detonation, overheating, etc.).

PPPS: There's no need to worry about blow-off valves for your turbo on the TD42 engine, because the engine does not have a butterfly valve on the intake manifold. As a result there is never a chance of boost building up (like it would on a petrol engine when you release the pedal), unless the engine stalls. Boost level is controlled by the turbo's wastegate, and that is controlled only via the wastegate actuator. Unless you drive a 3.0 diesel, in which case the ECU gets involved big time in controlling boost levels...

Re: EGT , oil catch can and intercooler fan install pics

It's more important on vehicles that have air flow sensors, air temp sensors, boost sensors, EGR systems, etc. downstream from the turbo (yes, I'm looking at you, ZD30!). These can gunk up if too much oil reaches them, give false readings to the ECU and result in all manners of failure.

On the TD42 there are none of these sensors to foul up. The downside of course is that it is not possible to optimise the engine's performance to the same extent as on the ZD30.

PS: All us TD42-ers need to worry about is that the inter-cooler can gunk up with oil. I rinsed mine out when I made changes to the fan a year or so back, and there was very little muck to be found (about 285 000km). Might be partly due to the self-draining properties of a top-mount inter-cooler, where gravity will return oiliness back to the turbo and inlet manifold after engine shutdown? :think:

Re: Front passenger window switch faulty

I had similar issues when I just got Chuck...

The right rear passenger window worked from its own switch, but not from the driver's combo switch. I went scrapyard hunting and found that the Navara used the same combo switch. The top may look different, but the actual switch underneath - including its connectors - is the same. After replacing the switch things are fine again :thumbup:
