This kit groups under one part number the gaskets needed to reassemble the top end.

Specifications

Brand: PROX
Manufacturer part number: 36.6416
Weight: 100 g
Engine: 4-stroke

When to replace it?

Coolant or oil seeping at the head/cylinder or cylinder/crankcase joint.
Coolant level dropping, bubbles in the radiator.
Hissing or black marks where the exhaust leaves the cylinder.

At every piston change and every time the cylinder head or cylinder is removed, even for a simple inspection. Gaskets cost little compared with the work of stripping the engine.

Fitting tips

Clean the gasket faces without scratching them (plastic scraper, solvent): they must be clean, dry and free of burrs.
Fit the gaskets dry, without sealant, unless the workshop manual says otherwise.
Refit a base gasket of the same thickness as the old one, unless you are deliberately adjusting the squish.
Tighten the cylinder head in a criss-cross pattern, in several stages, up to the manufacturer's torque.
While it's apart, replace the spark plug and refill the coolant.
After break-in, check the torque with the engine cold and make sure there are no leaks.

Frequently asked questions

What does the kit contain?
The base gasket and the head gasket.

Should I replace it along with the piston?
Yes: as soon as the cylinder head and cylinder are off, new gaskets go back on. It's the right time to fit a new piston kit and new rings if the engine has some hours on it.
