A rod containing the pinion designed to transfer motive power from the prime mover to the crankshaft via the pinion and main gear.Also known as the Pinion Shaft.

The external input shaft of certain gear operators, which drives the internal reduction gearing. The pinion shaft can accept a hand wheel or power operator.

pinion shaft is made of 4340 alloy steel through forging process. With great precision, the double helical gear machined on the shaft will ensure smooth power transmission along the whole tooth width and reduce gear gap significantly. As a result, hammering caused by change of speed will be efficiently eliminated.

How to Install the Pinion Shaft & Bearings?

1. Install the pinion bearing inner races on the pinion shaft by heating to 300°F in an oil bath, electric oven or induction bearing heater. Wait for races to cool before proceeding.

2. Install the pinion bearing outer races to the bearing carriers using a slip fit.

3. Place the pinion shaft into the pump before installing the bearing carrier assemblies. Make sure the pinion shaft is properly supported before proceeding.

4. Slide the bearing carrier assemblies and gaskets over the pinion shaft and into the pump frame, exercising caution as they meet the inner race.

5. Install the pinion oil seal and race onto the pinion shaft.

How to Remove the Pinion Shaft?

1. If necessary, unscrew and remove the key from the pinion shaft keyway.

2. Disconnect the oil lube lines and drain, then unbolt the pinion oil seal plate. Be sure to support the pinion shaft to prevent it from moving.

3. Slide the oil seal plate and spacer free of the pinion shaft.

4. Remove the pinion oil seal and race from the pinion shaft.

5. Unscrew and remove the bolts and washers securing the pinion bearing carrier to the power frame.

6. Use the jackscrew holes in the pinion bearing carrier and remove it and the spacer from the power frame.

7. Remove the bearing outer race and rollers from the pinion bearing carrier. The bearing inner race will still be shrunk fit onto the pinion shaft, and it is important to protect the finish of the inner race if the bearing is to be reused.
