Stihl 015 Oil Pump Drive Sprocket 3/8 Chain

thingiverse

Stihl effectively discontinued production of the crucial component required to convert the 015 chainsaw into a 3/8 chain drive. While multiple sources offer various sprockets, the specific oil drive sprocket has become virtually impossible to obtain. By carefully measuring the components that engage with this part, it was possible to design and 3D print an exact replica using a Makerbot printer set to a 60% fill rate. The loads involved in this system are minimal if the engine's oil pump is functioning properly within its designed specifications. As such, owners of 015 Stihl chainsaws who seek to upgrade their drive components will find it necessary to fabricate their own customized sprocket using advanced printing technology.
