PROX Complete Engine Gasket Kit for SUZUKI RM 250 2006-2012

The PROX 34.3326 complete engine gasket kit is designed for SUZUKI RM 250 from 2006 to 2012. When you open up the whole engine, every gasket removed must be replaced. The complete kit brings together the top and bottom end gaskets under one part number: cylinder head, base, crankcases, covers and exhaust, depending on the model.

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: 34.3326

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.
