This is an unusual question to ask but very important for me to finish swapping these motors . . .
I am putting a 1996 Polaris trail boss Fuji 250 engine in a 2000 Polaris xplorer 250 4x4 replacing the non running Robin 250 engine. Everything is "plug and play" very easy swap to do except I dont have the bolt that holds the drive clutch for the Fuji.
I have the bolt that was on the broken down Robin engine but it won't thread into the Fuji crankshaft so I am unable to install the drive clutch.

Was there a change in bolt size for the drive clutch when Polaris went to the Robin engine?
Can anyone tell me the size of the drive clutch bolt for the Fuji engine?
Can anyone tell me the size of the drive clutch bolt for the Robin engine?

 

Most replacement parts we got from Polaris for Fuji engines were Robin parts. They're all kinda tied together as even parts for Subaru were supplied by Robin. Subtle changes over the years,can't remember what changed and when on the bolts but the Polaris Parts site shows you the part numbers for each year model.You can check for any changes there.Browse
