KMP Inlet Valve Seat T400755
Reconditioning a head? The KMP Brand T400755 inlet valve seat is part of the valve gear that controls when air and exhaust gas move through the engine.
About this part
Valves, seats, guides, springs and seals work as one system. A worn guide lets the valve wobble and burn its seat, and a tired spring lets the valve float at speed, so these parts are usually renewed together during a head overhaul.
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
Fit new stem seals whenever the valves come out; they are inexpensive and are the most common source of oil smoke from the head.
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.
