8. Caged Roller Bearing's On Main shaft And Cluster Shaft
9. Reverse Idler And Input Shaft
10. Balanced Design For Strength With Extremely Low Rotating Weight
Splined cluster shaft was designed for easy disassembly and reassembly for ratio change's. To increase the load strength the cluster shaft rotates on 4 caged roller bearing's. Thrust bearing's are used to decrease the end load friction when shifting thru the gear's. 2ND ,3RD and 4TH gears are interchangeable.
With the demand for lighter rotating weight Roltek designed a lightweight reverse setup standard with the 4-speed transmission. The 39 tooth gear is cnc machined and cupped out to reduce weight. The center of the reverse idler is turned down to also reduce rotating weight. Caged needle roller bearing's are useded to reduce rotating friction. The gear on the idler shaft is removable for easy gear change's.
