0.6 mod

0.6 module GEARBOX kits 23:1 and 11.5:1 ratio with 1/8” input shaft

Released May 1997, the 0.6mod tooth size provides greater capacity and operating life for large and heavy models. Stock numbers in the 650-6 et al series – same axle fit and gearbox style choices as the 0.5mod series. The heavy worm end-thrust load of large loads commonly results in overheating and failure, therefore the 0.6mod size is available only as premium ball-bearing worm shaft version for better life, operation, and reliability.
