Compatible Bushing Kit

This pack contains four bushings designed for Dayton rotary gear pumps. Each bushing matches the dimensions required for Grainger part 4KHJ1. Maintenance teams can replace worn bearings without sourcing individual components.

Low-Friction Operation

The bushings reduce shaft friction inside the pump housing, helping the mechanism run smoothly during daily use. Less friction means quieter operation and lower motor load. Replacement intervals stay predictable with the four-piece supply.

Direct Pump Fit

The parts install directly into compatible Dayton rotary gear pumps, requiring no adapters or modifications. Each bushing sits in the existing bearing bore, freeing bench time for other maintenance tasks. The pack covers multiple service cycles for a single pump.

Questions about this item

How do I install the bushing on a Dayton rotary gear pump and what step do people usually miss?

Press the bushing into the pump housing bore until it seats fully; the step most people miss is cleaning the bore and applying a light coat of compatible lubricant before insertion.

What maintenance or replacement will the PK4 bushing set need over time?

Inspect the four bushings during scheduled pump service; replace any that show scoring, excessive clearance or wear beyond the manufacturer's tolerance.

What limit appears first when the pump runs continuously with these bushings?

Heat buildup in the bearing journal typically becomes the limiting factor before the bushing material itself reaches its wear threshold.
