    Spare pin from an oil pump?


    Does anyone have a spare pin from an oil old pump:

    I managed to loose one whilst rebuilding the pump and they are not sold by Yamaha. Its an FX HO 6B6 engine but I suspect many others may fit, the pin is 3mm x 16mm.

    I know generic locating pins are available but I have no idea if it should be hardened or what grade of steel etc and I would worry that I used the wrong type and it may shear off during use.

    I've fabricated a pin for hydraulic pump that produced well over 3000psi from a new drill bit. Finding the correct size is the main thing.

    I found an oil pump drive pin for a Yamaha bike (part 93603-2202, ordered it on the off chance and its the same diameter to within 0.02mm, its a bit longer but that should be easy to sort out on the grinder or lathe. Being a Yamaha part for a similar job in a different engine hopefully it will be up to the job and I hope that part number helps anyone else out that stumbles across this thread.
