PROX Complete Engine Gasket Kit for HUSQVARNA TE 150 and KTM EXC 150, XCW 150 2017-2023

On KTM EXC 150, XCW 150 and HUSQVARNA TE 150 from 2017 to 2023, the PROX 34.6237 complete engine gasket kit fits in place of the original part. A full engine rebuild calls for new gaskets wherever parts have been separated. This kit saves you ordering gaskets one by one and makes sure the engine goes back together perfectly sealed.

Key features

• All the gaskets for a complete engine rebuild.
• Materials chosen according to location, from multi-layer steel to synthetic fibre (ProX).
• Designed to work with ProX pistons and connecting rods as well as with original parts.

Specifications

• Brand: PROX
• Manufacturer part number: 34.6237
• Weight: 160 g
• Engine: 2-stroke

When to replace it?

• Oil seeping at the crankcase or cover joints.
• Coolant or oil leak after the engine has been apart.
• Gaskets hardened, torn or stuck to the parts on disassembly.

During a complete engine rebuild (connecting rod, crankshaft bearings, gearbox) or whenever the crankcases are split.

Fitting tips

1. Clean all the gasket faces without scratching them and remove any remains of old gaskets.
2. Fit the gaskets dry, except where the workshop manual specifies sealant.
3. Replace the O-rings at the same time: a crushed O-ring can't be reused.
4. With the cases split, also replace the crankshaft bearings and oil seals and check the gearbox bearings.
5. Tighten the crankcases and covers in a criss-cross pattern to the manufacturer's torque, then fill up with oil and coolant.
