912UL Flywheel hub thread size

by Michael Petres in 912 / 914 Technical Questions 9 years ago

Hi,

Trying to find out what the thread size is for the 912UL flywheel, the thread which the puller tool attaches to...

Any suggestions will be much appreciated.

Thanks,
M

Hm, If nobody will help you I'll find my puller. It was metric thread but I don't remember dimensions. We made this tool by myself.

Hi Micheal,

All info like this can be found in the Parts Manual.

It is in sec. 24-20-00, page 5, line 24.
The proper torque for this bolt is also found there.

Roger,

I did look in the parts catalog... I am actually looking for the thread on item #17 in the parts catalog, the stator. Line 24, as I read it, refers to the bolt which locks the stator in place... the stator has a thread to which the puller tool attaches to...

Thx.

Hi Micheal,

To be honest I can't remember. I bet Rob knows.

I don't know for sure but I measured it and the pitch is 1.5 and the OD of the hub is 45.9mm so 46x1.5?
