1956 Series 62 Coupe restoration, engine, transmission question
« on: September 14, 2016, 12:58:36 AM »
I am restoring a 1956 Cadillac Series 62 Coupe in Germany.  Here are some pics along the process. The Caddy looked great from the outside, also the interior was complete and in good state... the truth came underneath..... the brown cancer..... 
ok one step at a time I started the long fight.

I lifted the body off the frame, repaired the rusted frame and started on the front inner wheel wells.

After that I decided some other kind of work might be a welcome change... As everything is off the car now I decided for a reseal and thorough cleaning of the transmission's internals. I took the engine and tranny apart. The engine showed one bent pushrod and lots of hardened gunk from oil.
The tranny was fine internally except some differences to the manual. All the transmission specialists I contacted made a big mistery out of it. They would need the tranny..I won't ship a tranny back to the states and my rule is learning by doing so I am not afraid of some deep inside tranny work.

When I took the tranny apart I realised that the internals of the shift valve body are not according to the manual. Before I started the car's restauration the tranny shiffted through the gears but I could take only a small drive at that time.
I am missing the neutral clutch valve and spring, thoses weren't installed in the shift valve body. Does anybody have an idea?

see pics

,,, Does anyone have advice were to by a new timing chain, lifters / pushrods?
What about that tranny problem. Could the modified shift valve block be part of a shift modification?

Harald, there were some modifications done at the transmission which are not included in the shop Manual. I cannot tell for the moment (I'm not at home); I believe these modifications are documented in a bulletin which I have at home.

Harald,

Timing chain and lifters are off the shelf items.  You can get them at rock auto, summit racing, etc.   I have used the sealed power brand with no problems in my í58.   Falcon Performance has a lot engine parts and I have their quality is good.  They have push rods.  At least for me I buy often from Ebay or Amazon where they send packages through their global shipping program.  You pay duties and taxes up front and it it delivers like a domestic package   It ends up being less than mail and paying the duties and VAT here.  It might be similar in Germany. 

For transmission parts try Autotran, (autotran.us).  Iíve bought parts from them and they were good. 

Closer to you is also Andreas Winterwerber Cadillac Service, (cadillac-service.com).  Iíve not bought from them but heard that they are good. 

Good luck,
Peter

Harald,

Welcome to the forum and great car!

Yes there were many changes to the 1956 Transmission. Attached is a picture that should explain it.

Now the engine is on the way .... doesn't look too good.... I guess I will need oversize bearings, a crank job and maybe also new, bigger pistons to have room for a bore and hone job.

and the heads. I am thinking about hardened exhaust valve seats to have less trouble with lead free gasoline.
