Gritzner/Domestic Belt & Clunk
Hi all. For my level of exp. so far restored a 15-91 (easy) and rebuilt the tension and replaced bearing washer in a 925 (not easy).
This Gritzner/Domestic came to me after sitting idle in a cabinet for thirty or more years.
Loving the design, and the idea of the dual needles and dual tensioners.
I see others of this model with toothed red drive belts. Would like to do that instead of the slippy black rubber ones it has as spares. Is there any standard source for things like the wheel race and the motor pulley?
Also I am really sensitive to kerosene. Will odorless paint thinner work as well to loosen the hardened oil or to I need a HEPA mask? Some interior part is really stuck hard and cannot turn the wheel without effort and a 'clunk'. Took off the motor and back plate and no corrosion inside. Just flood it?
Looking to disassemble the tensioner also, it has some rust starting. It looks like a block, is there anything behind it I shouldn't touch?
All wisdom appreciated.
