play in Diff
jacko - 4/6/12 at 03:10 PM

I have just been looking at the info and i think i know what to do can some one tell me if i am right please

Looking at the rear of the diff
If i slacken the castle nut on the right will this allow the left castle nut to be tightend moving the crown wheel to the right and taking the play out between crown wheel and pinion cogg ?
This should reduce the play on the prop pinion ? yes or no

Thankyou for any HELP you can give me
Jacko

Yep! but not quite that simple, you need to take off the rear cover and measure the backlash, and for that you will need a dial gauge. I think if you do a search there is a post that explains how, and you do need to put some pre-load on the bearings after. Cheers Ray

Or, alternatively, adjust so that you have almost no detectable backlash on a the diff, put the lid back on, fill with oil and see if the problem goes away. Just be sure to check the backlash at different crownwheel positions as it might vary a bit on a well used diff....

They are not the rocket science some people make them out to be....

Some good info (including the rebuild manual) here: http://www.locostbuilders.co.uk/viewthread.php?tid=156096

Oh, and if you want your skin to stay in place, get the thing out of the car. It will make your life a lot easier!

Hi All thankyou for all the help
I have had a go at the ajustments today and am very happy how it has gone
The only small amount of play is between the drive shafts and the small cog in the diff (forgot the name of this cog)
