2350 front structure gasket

[Signature620]

Front and rear housing gaskets are very common failures on cm2250/cm2350 ISX engines. I believe they changed supplier or material for the rubber in the gaskets and it eroded easily.

There was a bulletin released in Australia that instructed techs to replace the gasket then run a bead of RTV down the intake side of the block after the gear housing is refitted.

Personally, I apply a very light amount of RTV to both sides of the steel section of the gear and flywheel housing gaskets. Others use anaerobic sealants like Loctite Master Gasket.

I can't comment on job pricing in countries other than Australia.
