Do You Know What This Part Is On A Gs550b Motor

[Guest]

Hi there. Can anyone tell me what this part on the motor is for and what it does please? It is the raised part with a hex head bolt in the top of it. It is directly behind the oil pressure sending unit towards the rear of the motor near the rear top engine mounting. It only appears on the 550 motors.

i don't have a 550. don't know i have seen one.
But, looks like your pretty far a long in disassembly. Its just one more "hex" to unscrew and see!

A guess... because of the height and its proximity, i would say some kind of spring and detent ball (for transmission or shifter) resides in there..

Judging from the postion of it I'd guess it's a stop for the shift drum in the tranny. Probably has a spring under that pushes on a shaft.
