How do you un-wind a diff??

(1/9) > >>

stratie:
Old fella down the road has got an s111. When you put into low box, it jerks. The wheels spin, then move normal, then spin again.
When you push the yellow leaver down it's even worse.
I was told that the diff's could be wound up.
Any one have any info for me?
The fella need's his landie to drive down a very muddy rutty farm lane. He's a smashing chap, so i would like to help him out. He's been driving landies for 40 years, but has allways got the garage to sort out his problems. What with the credit crunch, money is tight, so i thought i would do my bit and lend a hand.
Cheers
Brend.

It should already be in 4wd when in low box; pushing down the yellow lever shouldn't have any affect.......  :-k

Does it drive ok in 2wd? What about in low box with the front prop removed?

At the moment my instinct says it something in the transfer box, maybe front drive output related.

Oh one left field thought!..........how long has he had this LR. Someone has put a RR diff in the back axle and left a std Series LR diff in the front have they?! Different ratios and might give this effect?

crazymac:
The easiest way to unwind one is to get it on a wet or very loose surface. That should at least rule out a diff being wound up! I'm trying to remember how the levers work on the series machines so correct me if I'm wrong!

Red lever down = low box 4x4
Yellow lever backward = 4x4 in high ratio
to return to 4x2 high ration you bring the yellow lever back then forwards again, and the red lever pops up again.

Andy, the fella has had the landie from new, and yes it drives spot on in 2wd.

Crazymac, i was told to drive it on wet grass ect, but i was told to drive it around in circles?
As for the levers.....Red goes back, and yellow goes down. Not that it matters, i know what you ment  :D

Cheers for the info guy's, i'll give it all ago.

stratie:
How or why is it poss for a diff to wind up? If i can understand how and why, then i might get a better understanding of whats up with Norms landie.
Any one know?
