John Deere 5076, 5082, 5083, 5090, 5093, 5101 and related 4045-powered equipment using this water-pump family

Product Overview

The pump circulates coolant through the 4045 engine and radiator. Seal leakage, bearing play or impeller problems can create coolant loss, overheating or belt-drive noise, and continued operation can lead to much more expensive cylinder-head and gasket damage.

Research identifies several Deere numbers in this pump family, including RE505981, RE500737, RE500734, RE546906 and RE505980. Model names alone are not enough because 4045 installations can use different front covers and accessory drives.

Key Features & Performance

  • Cooling-system replacement for John Deere 4045 applications

Frequently Asked Questions

Q: Why are several Deere numbers listed?
A: Water pumps are often superseded or cataloged under related service numbers. Match one of the references to the machine/engine catalog.

Q: Should coolant be reused after pump replacement?
A: Use coolant that meets the engine manufacturer specification and address contamination or corrosion rather than returning dirty coolant to the system.

Confirm 4045 engine build and water-pump reference before ordering.
