What would be the result of machining the stator blades off the impeller side of the stator? Would there be any adverse side effects?
In hopes of lowering the stall of the converter, machining down the impeller or primary pump side of the stator would open the window-area of the stator and lower the stall; however, this can be a significant trial and error procedure. Another troubling side effect: cutting torque multiplication. Lowering this limits the amount of power, and it could make the vehicle feel sluggish at takeoff.
Another suggestion, bend the blade closest to the inner diameter toward the stator. This will decrease the impeller to turbine clearance.
How would I go about correcting a cracked hub for a converter from a JCB forklift using a PS 750 5-speed powershift transmission?
Easy fix: Purchase a replacement unit from Sonnax. If you’re not interested in buying a replacement, or simply cannot sacrifice the time, you can machine the weld off and reweld the TC with a better weld and drop a bead of weld on the inside of the machined flat. Just don’t use a hot weld in fear of distorting the weld.
