What we’re working on.
Car in the garage. Reference shot for rear ride height. It’s too high!
Out in one chunk. This is an early rear end and has Hardy Spicer driveshafts.
Peter Renou’s leaf spring compressor. Made a dangerous job very safe.
Pinion shaft. Big oil leaks, excessive end float and back lash.
Silicon gunge in the pinion shaft, or how to get through an English MOT!
Note this is an early diff.
Remains of double row thrust ball bearing
p/no 48704 (SKF 54-205) rare & hard to find!
Reason for bearing failure was blocked oil way. Excess gasket goo.
Old & new gland nut p/no 38-32546
Inside all was fine.
Crown wheel in good shape, no wear.
It’s always fun looking for the Lancia date stamp on each part. 1938 shows the carrier has been replaced
Ready to go back together. New pinion shaft bearings & silent blocs for torsion bar guard tubes.
Checking for backlash.
Torsion bar & rear wheel hub.
Slightly bent torsion bar.
Wear from rubbing inside guard tube.
Torsion bar bearing. Couldn’t find replacements, but very little wear. So just cleaned out and packed with grease.
Muck from torsion bar bearing
New torsion bar clamp rubbers
Wheel bearing mess. Not something to think about at 100 km/h. So new sealed bearings for here.
New flex couplings from Cavalitto.
Also replaced all silent blocs, 10 in all (later types have 14)
An original flex coupling!
Aligning under car.
Handy motor cycle lift.
All back together, lower ride height. Now have to sort rest of drive line and radiator position.
Took her for quick drive around the block. Diff whine on over run!
From “Servicing The Aprilia” 1937. Some information on working on the rear end.
