Datsun Roadster clutch fan replacement spacer block
68 - 70 Light weight machined Nylatron Fan spacer block. This spacer block is used to replace defective or missing original clutch fan unit. Our fan spacer block is universal and will properly index the 4 blade fan as well as the 7 blade fan. Be sure not to buy a spacer block that will not center the fan. Fans not turning concentric will oscillate and or wobble causing bearing failure in the water pump. You can not center the fan on the 4 bolts. This is dangerous and it just causes premature failure to expensive parts. Comes with a nice instruction sheet.
The top photo is of the backside of the spacer that mounts directly to the water pump flange replacing the original fan clutch unit. You must remove the original fan clutch completely to install this replacement unit.
