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 ?

@[deleted]
i will have to have a think about the diff will he go cheaper ?

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

I will ask him for you mate

evocarlos

keeping them in the right order

stripping the races out of the casings little home made tool 🙂

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 :confused:

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

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
