Using this diagram

The exploded view above shows the hydraulic unit for the Dayton 4YX97. Each callout number corresponds to a component listed below it — find your part on the drawing, then match the number to the listing to get the current part number and price.

Ordering the right part

  • Individual components — seals, o-rings, pins and springs are listed separately
  • Seal kits — if more than one seal is weeping, a seal kit is usually cheaper than buying the parts individually
  • Complete units — where a pump body is scored or cracked, replacing the unit is often more economical than rebuilding it

Not sure it matches?

Check the number stamped on the hydraulic unit itself against the drawing. If it does not match, call 1-800-669-7554 — we can identify the unit from a photograph.
