As a guide in normal use, consider the following:
- After replacing 10 H.P. Stainless Steel jets, it is time to replace the seals on the
pump using a Seal Kit.
- At the same time, also replace the seals on the By-Pass Valve using a By-Pass kit
- Do a whole pump changeover at 1,000 hours. (Con Rods, Big Ends & Crankshaft)
- Pistols, swivels & H.P Hose damage is usually uneconomical to repair. Replace
when necessary.
- By-Pass Valves will take 3-5 rebuilds before body wear becomes too much and
replacement is needed.

- Check wheel bearings periodically - re-grease or replace when necessary
