KMP Inner Inlet Valve Spring T400761
Reconditioning a head? The KMP Brand T400761 inner inlet valve spring is part of the valve gear that controls when air and exhaust gas move through the engine.
About this part
The valve train opens and closes each cylinder thousands of times a minute. Small amounts of wear here show up as lost compression, oil burning or a rough idle.
When to replace it
- Blue smoke on start-up from worn stem seals or guides
- Low compression on one or more cylinders
- Burnt or pitted valve faces and seats
- Weak or broken valve springs found on inspection
Before you order
Have seats cut and valves lapped by a machine shop when fitting new valve parts, and check spring free length against the engine data before reuse.
Not sure it is the right one? A photo of the old part and the nameplate of the machine it came off is usually all the counter needs to confirm a match.
Questions
Should I replace all the valves or just the damaged one?
On a generator engine that runs long hours, most workshops replace the full set of the affected type so the head wears evenly afterwards.
