4wd lever stuck

[NOALSY]

hey guys, Its been awhile since my first introduction post so i thought i should put up an update on the 91 L series project.

so as i mentioned earlier my clutch was shot so i decided to replace it my self. instead of removing the engine i removed the transmission for a couple of reasons. Any way the removal was pretty smooth with the exception of the spigot bearing, that was a PITA! however whilst removing the trans the 4wd linkage U joint got mangled a bit but i fixed it up. (it wasn't bent or anything)

so i replaced the pressure plate, thrust bearing, spigot bearing, friction plate and shifter linkage bushings. an Exedy HD clutch kit was installed

after it was all back together i noticed that the 4wd lever seems to be jammed in 4wd high, it doesnt want to budge an inch even after reversing. there's no gravel or lose surfaces around me to try to chirp it either.

It wasn't jammed when i removed it. Its pretty darn unusual

My suggestion would be to remove the 4wd selection from the gearbox and try shift it on the gearbox directly. Not sure how much of a pain this is with the gearbox in the car but its probably not all that easy...
Given that you have not had the box apart at all it indicates that it is most likely to be linkage related.

When you say that it got damaged - in what way was it damaged?

I agree with DM.

Having spent over an hour adjusting the brackets and locking plates on a fold-down clothesline recently, it is easy to see just how important the tolerances and alignments on even such a crude and simple device are critically important. The alignment and clearances on a gear shift linkage are far less crude than this!

Some things are beyond a man's capacity no matter what his experience.

Eat your heart out, Peter .

The bloody thing now works perfectly for the first time since we moved into this house some 7 years ago ... Even SWMBO can work it, every time :ebiggrin:



Three nuts and attendant spacers on each side. They need to be in exactly the right relationship to each other, and the locking holes punched into each of the two side arms of the unit. These brace and lock the clothesline in position. I'm sure that you're familiar with design ... :iconwink: :lol:.

At a very rough guess, I reckon that the three nuts need to be adjusted with a tolerance of around ±5/1,000" relative to each other, and relative to the adjustment on the opposite side! This translates to about ±10-20° either way on each of the three nuts. That's just an incredibly fine tolerance for something that's so flaming crude, with a thread that's about 1/4" W!

So getting back on topic, there is more than just a possibility that the slightest unintentional bend in Noalsy's linkage shafts is causing the problem.

My Austin Kimberley had three cables that worked the gearbox from the floor stick. They were similarly sensitive to being out of adjustment, but at least there were written tolerances for the required clearances, and fine threaded adjusting nuts either side of the gear lever connections to these cables.

All the best with fixing your problem, Noalsy.
Maybe shoot off a PM to Bennie ("El Freddo"), he knows the L series upside down and back to front. He will almost certainly be able to diagnose your problem, and help you fix it.

got the dang thing fixed, turns out the 4wd selector fork had been twisted up side down and for what ever reason the fork only moves when its in the right position.

luckily it had nothing to do with the linkage.

thanks for all the help guys hopefully this will help some other folks.time to fire the old girl up! :biggrin:

^ Good to hear, Noalsy.

Hope it fires up obligingly, and the clutch now works properly.

Glad you got it sorted. It may help to take some before pics when you pull things out to make it easier to reassemble.
