quick question... I have seen it on a thread somewhere before and I didn't save it which was stupid... no amount of searching has found it...

does anyone have the trans case bolt tightening sequence diagram at all?

thanks in advance

I just had my engine case and transmission case Chromated by Chris Childs. He did a great job! You can check out the pictures of it in my thread, page 87.

It is also a “sticky” in the main section.

All the split case transmissions that I have had or disassembled have been bare castings, no paint or treatment.

Does anyone know the gold color they painted the cases?

I just tore a split case down in my 55 build. Documented it fairly well. I will be going to a MCM to rebuild it with Scott in the near future. I will document the entire process during the rebuild, as this a much needed for the community. Keep watching my thread for updates on that trip!

Out of curiosity, what is the level of difficulty in doing this open, clean, repair of a split tranny? Considering a DIY. Out of 1-10, 10 being difficult, what would you say this is rated.

All things said I am a quick learner and can process information well.

It’s mentoined in the type2 shop manual on this site, page 90/92.

Split gearboxes are the same for type 1 and 2, except for the flipped ring gear (because of the reduction gear boxes on a type 2)

I’m not sure whether you would be able to secure both axles in an assembled gearbox to reach such torque specs btw.
For remounting the nosecose, you should measure the bearing preload and adjust this with gasket thickness or quantity (page 86)

I'm reinstalling a rebuilt nose cone on a 1960 Split Case Trans. Upon inspection both the main shaft and the pinion shaft nuts were loose. I want to make sure they are properly torqued before I reassemble.

Can anyone speak with authority to the torque specifications for these two nuts?
I know they get held in place with the locking tabs. How could they have gotten loose?

Can I simply torque them to spec. and they put the nose cone on? Or are there other considerations/measurements that need to be made?

Why don't they or anybody make performance gearings for these split case transmissions??? that would be great to have these transmissions more suited up with our 36hp performance engines ..

Great! Good to know. Thanks.

Transmission went back on the car and seems to work just fine other than a leaky nose cone so it will come out and get that fixed some day.

This topic inspired me to consider jumping into my split case.... it then I got to page three and there is no outcome. Would be nice to know what happened with this before I take the leap.

Why not post a picture of the engraved number? sometimes having several sets of eyes is better than one.
