GearWorks 36 Spline Spool

The GearWorks 36 spline spool was designed to address several problems encountered with other manufacture’s spools.
First and foremost was the issue of breakage of the bearing journals due inadequate material thickness on other 4 inch bearing type spools. Years of practical experience told us that the 2.562” 40 spline axles were more than strong enough; we decided to size it down four splines to 2.375” 36 spline.
Second was the required modification of an already very expensive carrier bearing, our 36 spline spool uses the Timken L713049 just as it comes out of the box.
Third, some spools center the axle in the center of the spool, this is usually the thinnest section in a spool and most prone to failure, in our spools the axles are centered at the ring gear mounting plane, the strongest part of the spool.
