I'll propose an idea:

The motor mounting holes are close to that thread OD.? So there is no real space to manouver the motor's pinion drive gear into the gearbox first input gear.? If it is too tight you will get a noise from that.?

One option is to enlarge the mounting holes of the motor flange, but the mounting flange is maybe 1/4 inch thick.???

A simpler alternative is to file down the OD threads of the mounting bolts, just below the bolt head, of a distance the thickness of the? motor mounting?flange.? You must still have the threads past the motor flange to screw into the gearbox mounting holes.? Then by reducing the bolt diameter just in the thickness of the motor gjsnge, you will get some adjustment leeway to the motor mounting, so you can lighten up a tight fit of the pinion drive gear.??

You might want to get some spare 4-40 (x 1/2?) inch stainless steel allen socket head bolts to play with in case this idea?doesn't work!??

All the best,
