The HUDY 107051 kit delivers the essential tools for maintaining .21 engines with accuracy. The package contains purpose-made pullers and pressers for smooth removal and installation of front and rear engine bearings, plus exchangeable bushings and optional collets to suit both .12 and .21 engine sizes.
Made from HUDY Spring Steel and black-hardcoated 7075 T6 aluminum, every piece in this kit is CNC machined for tight tolerances and repeatable performance. The compact layout keeps the weight down while remaining comfortable to handle during longer service sessions.
The tool kit supports a wide range of engine bearings via separate collets and presser adapters sold by HUDY. Available options include:
The #107061 collet fits inner diameters from 11.5mm up to about 12mm, while the #107064 collet covers bearings up to roughly 14.5mm, giving broad compatibility across common engine bearings.
