1979??

check your manual release plug. If it has a brass seat then you can't fix it anyway. Assuming that you have steel check-valve seats then ....
the tall spring goes with the down pressure regulation valve
the up PRV spring gets 3-5 shims
the down PRV spring gets 1-3 shims
the small bypass valve spring may or may not have a brass washer under it

after assembly, pressure test. disassemble and shim as needed to achieve correct pressures. Add shims to increase and remove shims to decrease.

Re: 140 trim pump

then loosen the four screws on bottom of valve body and motor armature should start spinning. if its a new motor being put onto existing valve body then that is a common problem. If he opened up the motor then it is more likely to be the brushes.
