Here i will try to document what happens when i try to install 45%lsd from omega to a early c-clip opel GT rear axle.
I bought a omega lsd and started with the axle strip down.
Original differential is about 5mm wider than lsd unit, to compensate that i needed to make the following modifications.
1) First machine lsd to take original size bearings.
2)make a bushing for one bearings so i can move it outwards about 2mm more
3) take 3mm off from the crown wheel to get located like it was in original unit. That depends on your rear axle ratio.
This is what is done already, took the machinist almost half day to get the lsd unit and crown wheel done. Tomorrow i will be the installation back to the axle housing and adjusting the differential by moving different sized spacers under the bearings.
4)Half shafts will be machined after i have the lsd in so i can get correct length for both half shats, because one need little shortening and other stays the same.
Because i have early axle with no good c clips, i will be converting it to newer style bearings and makeing it to take opel rekord (VKBA 992 = 361984 DA
d 35 x D 67 x B 22,5 x C 21 mm) bearing.
That means that i have to take Alot of material off it. Original diameter for the bearing contact area was 47mm so it needs 12mm taken off.
Everybody said that i will brake after that, still i think i have to try that on myself (same conversion has been done in finland and raced 5 years in historic class and still going)
5) after tha shafts and new wheel bearing are in, i need something to hold the bearing on the shaft itself. For that use my plan is tu use a special bushing what will go inside from the wheel bearing on the shaft and that will be installed glowing red so it stays in the shaft and holds the bearing and the shaft not leaving from the axle.
6) Also a new adapter will be made to hold the bearing inside the tube, that needs to be 68mm diameter. Because the new bearings are 22,5 wide it means that they come about 5,5mm over (hanging on the air).
Oil seal will be moved inside the adapter and the adapter also get small groove for o ring to seal the adapter and axle tube. Tomorrow more pictures going. Sry for the ms paint made drawings.
