Frequently Asked Questions

It supports the pinion shaft within the pinion housing, minimizing friction and wear to keep the drive running smoothly and quietly.

Check your model’s parts manual or exploded diagram. If the pinion/drive section lists 102873, it’s the correct bearing. Serial breaks may apply—always verify against your exact model and revision.

For correct tolerances and longevity, use the OEM Graco 102873. Generic bearings may not match internal dimensions or load ratings, risking premature failure.

Play in the pinion shaft, grinding or squealing noises, inconsistent drive speed, or metal debris during service are common signs the bearing needs replacement.

Installation is typically a controlled press-fit into the housing. Use appropriate drivers/press tools and follow the service manual to avoid misalignment or damage.
