Diff inner axle shafts


68vitesse

Recommended Posts

Diff. on my Vitesse leaking from inner axle shafts so need to replace the seals.

Removed one from a spare diff. to get idea off job but as many posts say a bugger to remove the bearing, very little space behind it. If any one has done this what sort of puller was used as I believe just pulling on the outer race will only damage the bearing, picture in WSM not helpful.

 

Many thanks

I would dream about getting a set of replacement bearings ready to refit them on re assembly

 

grip the old bearing firmly in a vice and you can tap the shaft out , this may ruin the outer race hence you may need new ones

 

the Churchill drag shown in the WSM is /was   pretty universal in the trade and the cups to fit are dedicated with a thin lip to locate behind the bearing ,  theres no room for any 3 legged or any other DIY puller available  thin or strong enough to do this that Im aware of

 

so its DIY with a  good Vice , strong tea and hope   if the old bearing remains sound  ...you can resuse them

there is  ( like the hub faces)   some risk you distort /bend the location face 

 

thats why the churchill tool pulls the bearing .

 

but its a way of assisting even  using a vice or workmate to support a couple of plates  and whack it 

you have one to play with    just give it a go , dont get too emotive about it being a pig,  until it proves to be one.

 

it should knock out without excessive force ,

I THINK - it was some time ago - that this is the sort of tool I used for my diff bearing replacements; I bought an entire boxed set off eBay for peanuts initially to remove water pump bearings and vanes but found they were great for all sorts of uses. It slips in under the bearing and squeezes it off the axle without any pulling pressure that may cause distortion. Mine was around £15 second hand and has proved very useful so far. No idea where it is at present - in a cardboard box somewhere!

these  hydraulic puller is pretty bullet proof , had one for many years , have the arms but not the split cups 

get one if they are available ,, very useful

 

oldy inside is what resembles a mastercyl seal with grease as the medium, but you can get some wonderful force from it

Looking at a picture in an old Triumph Wsm, black cover loose leaf Vitesse 1600 Herald etc., page 3.110 Fig.21 appears to show the split cups behind the seal housing to remove the bearing.

Now have all the bits, bearings SKF but marked made in Bulgaria, seals and bearings sourced locally from specialist seal and bearing suppliers.

Thanks Paul - I picked a pair of bearings up from James Paddock with no maker or bearing number shown so possible suspect quality.

Hi I have a bearing removal kit see pic , you can borrow if you want if you think its suitable . It has a hydraulic ram rated at 6mt

We live in Pakenham just outside Bury st Edmunds - Ive only used it on small jobs so far and its been very good 

Regards

Many thanks for the offer, Paul, but the stub shafts are now stripped of bearings and seals.  Just a little worried about quality of unmarked bearings I have bought, also the seals are nowhere near the quality of the 45 year old ones that we have removed.  Just hope we don't have to repeat the job in a year or two because of quality issues.

Its a typical classic,, they have more reason to sell it .........than you have to buy it

one day it will be alright on the night

 

keep smiling a lot of graft has been done to get it where it is there are always annoying add ons that

are there to bug the latest owner.

 

the drive smile cant be far away

In Africa when asked for number of bearing, if anyone else needs them.

 

Bearing SKF Explorer 6205/C3

 

Seal pack marked IS 162-112-037 R23 seal marked 28.57 41.27 9.52 also has the number 2 and a symbol like a Yale type key.

 

I bought two sets one for my long term project.

Just in case someone looks at this in the future and doesn't have a press I did manage to remove the bearing and change the oil seal on my Spitfire without one.

 

I placed two solid metal strips on a vice below the oil seal retainer and then with progressive force tapped the inner axle shaft out using a block of wood and club hammer. Conscious of comments about damaging the oil seal retainer I kept a careful eye on progress.

 

Changing the oil seal was relatively simple and certainly looked to be the cause of the leak. I took the precaution of having a new bearing to hand and although the old one looked to be in fine fettle I did replace it with the new one. To do this i put the shaft in the freezer and the bearing in the oven as per the You Tube video. After a while I took the bearing out and amazingly it just dropped into place on the shaft. I was concerned as once cooler the bearing seemed very stiff and I thought I had ruined it (maybe i have) but with the application of some gear oil it was soon moving much freer.  It is now back on the car and after a gentle test drive and a blast up the M11 (it got past the A414 Pete) to Duxford all seems to be good.

 

Just one word of warning; when you get the bearing out of the oven make sure you have a good grip of it. You wouldn't want to try and chase it round the kitchen floor with one hand trying not to let it melt the lino whilst with the other hand trying to get a knife out of the drawer to pick it up. Not that I am saying that would happen of course...
