CA160 Cylinder Studs

Long story short, the CA160 uses two slightly-longer cylinder studs than the CB160 or CL160. This is because of the difference in how these motors mount to their respective frames.

When I rebuilt my CA160 motor, one of these longer studs was stripped and I had a helluva time finding a replacement.

I purchased a parts book a while back, and it has the proper parts numbers and diagram.

Rear-most center pair of studs: 90031-225-000
The other six: 90031-216-000

If you look closely at the top of this ca160 motor, you can see the longer studs.

Here you can see a CB160 motor, and the studs are the same length:

On my CA160 parts book, the studs are 21 and 21A here:
