Rebuilding a 300 Hirth into a MOD motor
Another view of the ramp plates. * * * Here is the plate installed on our clutch.
Another view of the clutch before the ramp plate was bolted down. * * * Here is the red lock plate and the yellow (gold) cad plated bolts. I heard from some "Arctic Cat old-timers" that the lock plates that came with the rev kits were red, so I painted this one red (stock ones were either green or natural aluminum).
This pic shows the reassembled recoil with a new cable bushing and a new foam dust seal. * * * Here is our almost completed engine (intake side) showing the Tillotson HD with the "top pull" cable mount installed.
With the clutch slid on the crankshaft, we're almost done. * * * Another view.
With the clutch bolted on and the other small details taken care of, I think we're done!
Exhaust side. The exhaust stub will be replaced with a side exit megaphone.
Stainless steel recoil bolts and a new "HIRTH" decal add a nice touch.
Looking good!
