Pfaff 1445 timing belt replacement tips/tricks wanted

[SeanBroecker]

I think I know a good amount about model Pfaff 145 but that does not have a timing belt.  I have a service  manual for a 1445 but that doesn't include replacing a timing belt.

Has anybody done that repair?

Thanks,

Sean

Thanks...  I thought that was where I posted.  I get lost in rabbit holes.

You were in sewing which could be anything dealing with sewing, most often saddle stitching and such.

Starting to think nobody has done that repair...?

Pfaff 1425 should be close to the same as the 1445.

Where do I find the directions for replacing the timing belt on the 1425?

OK.   watch a few utube videos on changing belts on singers.  Pfaff much the same.   You have to remove the balance wheel, and the bushing that the main shaft goes in.

Alright I got the upper shaft bearing ring out.

The lower shaft has 2 more bearing rings and 2 cams that need to be removed for the belt to clear.  

Anything to help with that?
