Direct replacement for Husqvarna 137

This new crankcase fits Husqvarna 137, 137e, 142 and 142e models with two-stroke, single-cylinder engines that use forced-air cooling. It restores the sealed lower end so the piston and crankshaft can build compression again. The part arrives ready to install with no extra machining required.

Replaces a cracked or scored original crankcase

When the factory case develops hairline fractures, bearing-seat wear or scoring from debris, compression drops and the saw becomes hard to start or loses power under load. Swapping the case is worth it when the crankshaft and piston are still within spec and the rest of the powerhead is sound. It avoids the cost of a complete engine assembly.

Bolts into the existing powerhead

The crankcase mates to the cylinder, starter side cover and fuel tank using the original fasteners and gaskets. No specialised tools beyond a basic socket set and torque wrench are needed. Reusing the original crankshaft, piston and ignition components keeps the repair focused and frees up budget for fresh bearings, seals and a new gasket kit.

Questions about this item

Will this crankcase bolt onto the existing mounting points on a Husqvarna 137 chainsaw?

Yes, it is manufactured to match the original crankcase dimensions for the 137 and 137e models, so the factory mounting holes align without modification.

What is the correct torque sequence when fitting the crankcase halves on a 142e engine?

Tighten the case bolts in a criss-cross pattern to the manufacturer's specified torque, and apply fresh gasket sealant to both mating surfaces before assembly.

Which gaskets and seals should be replaced at the same time as the crankcase on a 142 saw?

Replace the crankcase gasket, both crankshaft oil seals, and the cylinder base gasket to ensure a vacuum-tight seal on the two-stroke engine.
