you going to replace all the bearings while its apart?

i am yes there cheap enuff at £180 for a full set of snr

My mates selling a quaife diff for a M32 if you fancy upgrading while its in bits

depends on the price ? can you find out for me

you should replace them as a matter of course whilst the box is apart, I used Timken in mine which have been fine

thats the plan after seeing the outer races of the inner bearings it was then a defo yes there getting done lol
going to go with the SNR the info on the net shows there now used in box's after 2006

the case is now in for cleaning will see what its like in a couple of days

ended up sand blasting the case it did not come out as i had expected after the acid dip


much better




ordered the bearing and made a start to removing them


main input shaft bearings were a doddle




the bearings one the outer main shaft were easy


but i'm now stuck at this :s ?


dewismotorsport
i will have to have a think about the diff will he go cheaper ?

 

[dewismotorsport]

Good work looks like new, be a shame to touch it with dirty hands.

I will ask him for you mate

 

[dewismotorsport]

Just got a reply and it's sold.

 

[evocarlos]

yeah just a hand held gun asked the gaffer if i could do it in my booth at work i made a right mess lol

 

[Dave Gilbert]

iv heard it goes everywhere, i dont think my 50l compressor would be able to keep up

 

[evocarlos]

next bit off cant do any more my pullers not long enuff


keeping them in the right order


stripping the races out of the casings little home made tool


it works like this


and leads to this


same goes for the 3 outer races the pretty much fall out lol


shimms


case modifcation

 

[evocarlos]

heres the pics of the modification from the interweb

 

[evocarlos]

sussed out not having a long enough puller use 2


down to the bearing now


all parts for one shaft


and all parts for the other

 

[corsaZ22se]

[Dave Gilbert]

[evocarlos]

So how does the case mod work to help with preventing the oil starvation?

good question i was lead to believe it guides oil into the bearing

 

[evocarlos]

bit more done but the bearings have not come
ive booked in with the local machine shop to use there 50ton press tomorrow as im off work for a days holiday but going to hospital on friday so might be out of action for 2 weeks

here what ive got done

diy parts was bin


took the cap off the end off the pullers and clipped the cage on the bearing after a bit of braking it came off


the 2nd one was a right bitch and just broke all the way round had to resort to the grinder


its a thick ass bearing and took some getting thru but when it got close to the end it cracked thru on its own


all off with no damage


1st set of shaft parts washed and blown dry with the air line




2nd shaft parts in there


all the parts including the selectors all apart and laid out


and the 2nd one the same


heres hoping the new bearings come in the morning and i remember how it all goes back together lol

 

[Matt]

and i remember how it all goes back together lol

Now there in lies the tricky part

 

[evocarlos]

its not as bad as it looks
the gears will only go on where the needle bearing fits and the selectors go in between the gears
circlips to hold each gear on the shaft
the selectors go together easy once you push the balls in to get the ring on
3rd-4th

5th-6th
