Hello Everyone!
I am having a bit of trouble with an old motor, the shear pins keep breaking for no apparent reason.
It is a fine motor, but old so we don't have the correct info on pin size.
It has been checked by multiple mechanics, so we are sure nothing else is wrong with it.
So I was hoping that someone here recognized the model and knew the exact size for the pins? right now we are trying 5.0 x 34-35mm.
The serial number inside is: 31911.24, if it helps. and probably from the 70's.
I looked everywhere online with no result.
Thank you in advance.
