Kit contents and fit

This LAHDEK kit supplies a 10mm crankshaft with two crank bearings, two oil seals, a needle bearing, an E-clip, a clutch washer and a sprocket washer. It replaces OEM references 1132 030 0402, 9503 003 0340 and 9638 003 1581 for Stihl MS180 and 018 chainsaws. The package is aimed at owners or repairers of those specific petrol-powered, two-stroke, single-cylinder models.

Crankpin compatibility limit

The assembly is built around a 10mm crankpin; it will not suit saws that use a different pin diameter. The bearings and seals are sized for that shaft only, so mixing with other OEM variants risks oil leaks or bearing failure. No alternative pin sizes are covered by this set.

Straightforward press-in install

Installation is a matter of pressing the bearings onto the shaft, seating the seals and fitting the supplied clips and washers in the order shown in the saw’s service manual. The most common error is fitting an oil seal backwards or omitting the E-clip, both of which cause rapid loss of bar oil or crankcase pressure. A clean work area and correct press tools prevent those issues.

Questions about this item

Which version of the LAHDEK crankshaft kit fits my Stihl MS180 or 018 chainsaw?

This kit is built for the 10 mm crank pin used on the MS180 and 018 models and replaces OEM numbers 1132 030 0402, 9503 003 0340 and 9638 003 1581.

What does the 10 mm crank-pin size mean once the kit is installed in the saw?

The 10 mm pin matches the original connecting-rod bore so the piston assembly seats correctly and the engine retains its factory compression and balance.

What interface or standard does the crankshaft use, and what does that limit in practice?

It follows the Stihl 10 mm pin specification, so it only fits MS180 and 018 powerheads that were designed for that pin diameter.
