Eccentric Ring Gear, Mud Pump Crankshaft AH36001-02.10D.00 AH37001-01.05D.00 is herringbone. When assembly, the herringbone bore and crankshaft are of interference fit and fastened with bolts and lock nuts.
The gear is held in place with bolts and locknuts, but the gear pilot diameter may utilize a light shrink fit onto the crankshaft.
Position the crankshaft vertically with the single eccentric side up, supporting it from beneath with the gear-mounting flange.
Slide the gear over the pilot on the crank.This may require heating the gear. If that is the case, then be sure to uniformly heat all sides to approximately 200°F, and only heat as much as is necessary.
Install and tighten the bolts on the gear as per the Torque Chart on page 53. Always use new bolts when mounting the main gear.
