Rear spring

[davidwheeler]

I am currently engaged on dismantling the rear end (have not got round to mantling yet - it is all being very difficult!)    I need to change the spring and found that 36.362 was immovably attatched to the bolt 38.74127 - so had to cut it out.   Examination of 36.362 showed it to contain a roller bearing with traces of felt oil seal grooves either side, rather than the expected silentloc, but this seems integral to the body of the piece.   I cannot press out a bearing with 10 tonnes anyway!     Does anyone know any better than this or must I get the innards ground out so that I can fit a conventional roller bearing?

From memory, it is not a bearing assembly as such , but a machined housing with needle rollers, inner sleeve and cover, so it won't press out.

I will look out the bits and photograph them - although I see Noel is online and may have already done it ....

ps I think it seizes because the bolt bends between spring and bearing - it is drilled for greasing and is not solid

Umm, well yes I have had look! Simon is correct in that it is manufactured as a unit and is not designed to be disassembled. There are two possible options, on my car someone has ground them out and replaced the rollers with a PB bush, or Cavalitto have new replacements. The same applies for the top 38-360 part where the cable loops over.

The bearing in bits ......

[davidwheeler]

New is the way to go, thank you Simon.  Next problem is how to get this lot apart so as to renew the bearings.     I cannot press the torsion bar out of the tube using 38-74028 to press against.   I fear it will be very difficult to undo this item as well, probably much heat will be needed even though there does not look to be much thread, after which I can get at 38-74031 and remove the bearing.
All ideas welcome!
Unfortunately I also cracked one of the aluminium clams for 38-74020 which can be welded but if anyone has a spare please?
Thank goodness the wheel bearings seem OK.

[davidwheeler]

Making progress, 74208 has yielded to modest heat but 74031 remains intransigent even when red hot!   I fear I may have to drill it and weld it up again afterwards.

Simon how did you get the bearing bits out?

David you know the torsion bar bearing is an odd size, 45mm bore, 78m OD and 18mm width & difficult to find? The wheel bearings are a standard size and are probably worth replacing anyway as they are not expensive.

Sorry don't have a spare alloy clamp piece. You should also think about replacing the rubber doughnuts they hold in place, available in Italy at the same place you can find the odd bearings!

Noel, the bits shown are "new" repair parts, I presume supplied by Lancia originally. The bearing housing has a flange that is turned over once it has been assembled

I have found a clamp shell for David

I am full of admiration for what you guys are doing! Seeing the photographs of the cable-fitting reminded me of how grateful I once was to have had a spare. Beware, they may look OK, but the inner stands of cable can corrode without much to show on the outside. See my post under “What is the ideal emergency kit?”

I've found the bearings at Ferri Adelio but whence the rubbers please?

[simonandjuliet]

I have some NOS rubbers we could use as a pattern if you can't find them at a sensible price

In the same box I found these other rubbers, but not sure what they are for - do you recognise any of them ?

The one with the rear groove has part number 37.000.514 and I have a load of them .......

[davidwheeler]

38-74215 are the ones I think.  Mine are not too bad I suppose but remanufactured could easily be fitted at a later date.    I'll try Omicron tomorrow to see if they have anything.

[davidwheeler]

Omicron use 6009s which are 45x75x16 and make a carrier for them.  I shall wait on Ferri Adelio for a few days anyway.    I have managed to get the old bearings out, I made up a tool, shown below.  What is not seen is the 3 foot tube applied to the bar!   The bolts are to keep the tool in engagement.  I put the bearings in the press to start with and applied 3 tonnes to the bearing to press against the housing end thinking that may loosen things slightly.  One side then came fairly easily but the other fought to the last thread!

[simonandjuliet]

Looks like fun !

I like the pipe chain vice - plus can you show some more photos of the tool, did you make it ?
