The HUDY 107051 kit is made for precise servicing of .21 engines. It includes tailored pullers and pressers to remove and fit front and rear bearings reliably, plus interchangeable bushings and optional collets for both .12 and .21 engine applications.
All components are produced from HUDY Spring Steel and black-hardcoated 7075 T6 aluminium, CNC machined for accurate fits. This combination gives consistent results when pressing or extracting bearings and provides long service life.
HUDY supplies separate collets and presser adapter sets so the main tool body works across multiple engine sizes. The listed options are:
The #107061 collet fits bearing inner diameters from 11.5mm up to 12mm, while the #107064 collet covers up to approximately 14.5mm, making the kit compatible with the majority of small engine bearings.
