rev limiter, supressor

I am having some trouble with my truck and I suspect it is in the ignition. It is a 71o with petronix ignition and civilian cap/rotor/HT leads, and plugs. It idles fine on all four, but under load it misses and backfires through the intake. At idle I have good spark at all 4 plugs. All plugs except ...

Re: Pull to left when braking

Funny thing happened. It was time to inspect my brakes again. I pulled the drums inspected everything, put the drums back on and adjusted. When I started test driving again it pulled to one side just like it did years ago. I stomped the brakes real hard and it quit pulling. I think Jim L is right. I...

Re: installing differential breathers

That looks like the spot where they are shown to be in the owners manual. I did a little more reading last night and found out a bit more. First, some Unimogs use the pressure system at about 3 psi, but it is not on all the time.Second, some jeep people use a bellows on the vent. It sounds like the ...

Re: installing differential breathers

I have been reading up on fording kits for military vehicles. The Humvee (and I think the LMTV) have kits where a little air pressure can be feed into all the oil-filled units. The pressure balances out the static head of the water. The idea is that if there is a little leakage, it will be oil out r...

Re: installing differential breathers

Here is a picture of the transmission vent. This is taken through the inspection plate at the forward end of the bed. The breather is right there at the tip of the screwdriver.On my truck with 33"tires and no load it is about 30.5" above the ground. I wonder if this sets the factory wading height? I...

Re: ball joint crossover

SAV is closed until Wednesday which means they cannot get me the part until Friday. I want to do the repair before that if possible.

I have bought ball joints from SAV before and they worked fine.

I looked in the Moog catalogue. I can find the right threads, but the tapers do not look right.

Does anybody know if there is a crossover available for the tie rod ends?

Re: installing differential breathers

You can't see it unless you take the access plate in the bed off. Mine is on right now so I can't take a picture. It looked like a plain old breather with a tin hat. In the parts book it is shown as 2-20-32, part number 710.1.21.530.2 and is described as "ZF-0-732-612-004", "breather" in English and...

Re: installing differential breathers

My tranny, which appears to be original, does have a vent, which is shown in the parts book. Nothing else seems to be vented.

Transmission filler threads stripped

When I was checking my transmission oil I found the threads in the aluminum rear gearbox casing (710.1.21.522.1) where the reduction plug (900.19960) were mostly stripped.This is the highest plug, where you are suppose to put oil in. Has anybody found a way to fix this without tearing the transmissi...

installing differential breathers

I want to install the factory differential breathers for a trip I am hoping to do with some possible deep fords. I understand from a post copied below that you have to drill some holes in some "hollow shafts" that is described in a repair manual. I cannot find it in my repair manual. Does somebody h...

Re: Over filled portal gearcase

I found some old threads on here and it looks like it does happen. In one thread Jim L indicated it was something that the repair could be put off for a bit as long as oil was not getting on the ground. Sounds like the diff needs to come out but not completely apart. The parts look cheap, but it loo...

Over filled portal gearcase

I was checking the fluid level in my portal cases and one in back is very over filled. Can oil get from the differential into the portal cases?

Re: Breathers for gear boxes, '72 710M

I read somewhere that the transfer case is vented into the rear differential. I also read that on some later units the portal boxes are vented through the axles into the differentials. It is hard for me to see how a gear box could be unvented. There would be too much pressure across the seals with t...

Breathers for gear boxes, '72 710M

I want to make sure my vents are good and high for my various gear boxes as I am thinking about a trip next summer with deep water crossings, say 30" or 40". My unit does not have breather units on the diff housings so I am thinking about adding those. I believe there is one on top of the transmissi...
