Outer Limits 4x4 Board

HP hose is the lower one at the pump end - with the nut not the clamp end.

Leaking could be from the hoses but more likely the seals in the pump itself. If the oil gets onto the fan belt you might find yourself breaking fanbelts frequently so it is worth fixing the leak. Nissan sell a seal kit ...

I have used the 12V version and frankly I would never fit one again. The first one had an internal connection work loose after a couple of months. Fixed that and shortly after the motor shorted out. Managed to fix that and then made the mistake of fitting a second one for the Gigglepin head. Both ...

Thanks for that Scott and hj45.

Either solenoids or motor. You can use jump leads to test as in the diagram below.

If the motor/winch winds in and out OK then probably the solenoids or a loose battery connection or poor earth. It pays to fit an ...

Here's the diagram from the Warn manual




And here is how to test motor with jumpers

I must have an oddball. The nuts on my MQ and various replacement housings I have had ALL measure 52mm and a 52mm socket fits perfectly. Maybe the Aussie MQs were special - you guys have bigger nuts!

I have now gone to the GU locking system - much simpler.

I had a similar problem with the seals on the front diff on my MQ. On the MQ they are located at the diff head. Changing the seal made no difference. When I looked closely at the axle I found the seal had worn a slight groove in the axle surface. Fitted a speedi-sleeve about 3 years ago and have had ...

ok thanks guys looks like ill have to buy some poly and machine my own replacements, damn MK nissan engineers...

cheers daniels

The steel bushes are fine in the top if you lubricate them properly. The problem with the grease point is that when injecting grease it takes the easy route out and so ...

Years ago I was given a tool which had tapered square stubs to fit a variety of recessed plugs. I just choose the appropriate size, tap it in with a hammer turn it and and presto out comes the plug (with a bit of persuasion of course).

I am not familiar with the T-Max conversion you mention but it sounds to me like a kit to convert existing solenoid switches to wireless control rather than the usual remote cable control.

If this is the case then if one of your solenoids is busted this kit won't fix it.

Wireless control of a ...

Johnflink - low oil pressure can be caused by a clogged oil filter or insufficient oil as well as a faulty pump.

I am not that familiar with the L28 but the pump is, I believe, located under the distributor. Remove the distributor and the oil pump and drive unit can be removed as an assembly.

You ...

I got annoyed by the lights being on all the time at night so installed a couple of micro switches. One turns the lights on and off and the other bypasses the isolating switch so that if the pressure switch on the compressor fails, as has happened to me, I can still use the lockers as there is ...

Another cause may be an internally split flexible brake hose. The fluid can pass through one way, then the pressure flares out the internal splits not allowing the fluid to return when you take your foot off the brake pedal.

Would never have thought of that. Amazing what you can glean from these ...

In so many of these interesting threads we never find out what solution finally worked. So please let us know how you get on, TR3LOS351.

Sounds as if hi60 knows what he is talking about.

I would have a good look at the Megasquirt. Relatively inexpensive if you build it yourself and lots of info on the internet with really helpful forums.

I have done the efi conversion - Falcon EA to P40 engined MQ - and it has worked very well . There is a write-up and pictures at

Some comments I would make on the conversion are.

It would not seem too difficult a job to replace the standard Nissan plastic bushes with custom phosphor bronze ones which would last a lot longer.

Yep ...

I agree, RMP&O, the Parts Books are a fascinating source of info. I have the Jan 1986 version - and my Saudi Arabian truck has the H233 diff and came with the 3.9 ratio unknown in OZ - at least to ARB who told me when I was fitting one of their lockers to the front that there was no such thing as a ...

yup got one in my drive way but its a ug 160 with a p40 5 speed 1987 ute can not find any info on this type of ute ug 160 but that is whats on the conpliance plate if any one has any info on it plz tell me square lights

160 is the Nissan Model or Series No for what is known in OZ as the MQ/MK ...

Thanks RMP&O

Never knew what good that circlip did anyway - except to make you cuss when trying to put it back on.

looks like im going gq cv's!

one question tho!

How do your get the cv seperated from the axle? i thought they were pressed on fukn tight

One way I have found that works most of the time is to stick it vertically in a heavy vice with the CV at the bottom and then to give it a hefty belt with a ...

Thank you V8Patrol for this info. Very helpful.

Is there any MQ/MK conversion you haven't done?

David

Well the above circuit would have worked if the unit had been wired like that - unfortunately it isn't as I found out when bench testing and could not get the unit to park

I think (hope) that this time I have got it sorted. The unit's parking switch is a 2-way switch wired as in the revised diagram ...

Jumper cables are just fine. Just make sure your fingers, clothing etc are clear of the fairlead when you test it.

If your solenoids are shot you will probably find just one dead allowing the winch to wind one way and not the other. It would be unusual to have all solenoids dead at the same time ...

Here is Warn's diagram of the four solenoid pack taken from an old 8274 manual

If you think the solenoids are faulty you can bypass them and test the motor directly as follows. Just make sure that the motor is held ...

I think I have sorted it out. The insulated terminal block is a parking switch to make sure the wiper stops at the top of its stroke. The reversing of the wiper is achieved mechanically through a simple crankshaft action.

Does this diagram look right?

Thanks, Festy

Thank for that Chook. Helpful. I take it the washer works independently of the wiper.

I smashed my rear window last weekend and could only find a window with wiper. So either I plug the holes or try to get it to work. May not be worth the effort as I am not sure how, or if, the 24V wiper will work ...

Just trying to work out the wiring for the rear wiper on an MQ. Can someone tell me please whether it is a single or 2 speed, intermittent or not.

Thanks. David
