Crankshaft clamp needed to lock the shaft of RC nitro engines when tightening up the clutch nut.
This one fits O.S. engines: GT15, 105HZ, 91HZ / SZ / RZ (including R versions, i.e. HZ-R).
Replacement for genuine O.S. crankshaft clamp part number 71530530.
Print with 100% infill for maximum strength. Use any filament that can deal with RC nitro fuel (ABS, PETG, Nylon and even PLA confirmed to be working well).
