We have 30+ years in the powersports business rebuilding crankshafts utilizing CNC precision disassembly and assembly fixtures. It enables us to disassemble "un-rebuildable" such as twin cylinder cranks that other shops will not rebuild. We use fixtures just like the factory to reassemble all cranks.This allows us the ability for proper rebuild of Honda CR sheet metal stuffer cranks. Now the crank is true to factory specs or under. Without needing a hammer for truing after assembly.
Harley Davidson taper cranks are disassembled and inspected. Rod is resized to a .0008" running clearance.
When Twin Cam cranks are rebuilt a oversize pin is used. A strategy used on the new M8. This increases press fit to alleviate the possibility of twisting under running conditions. Then a steel plug is pressed into the center of the pin. This further increase pin fit. This also allows for rod honing making the rod bearing race like new. Pin bushing is inspected.
A precision assembly fixture is used for assembly. When assembled this way. Run out is under .001". This eliminates the need for old school 1960'S hammer adjustments to align. Tig welding is available for added strength.
Crankshaft Indexing Fixture
Allows precise indexing of 2 and 3 cylinder crankshafts
Provides a extremely rigid and true fixture during disassembly.
Pins are pushed perfectly straight with no possabilty for damage during disassembly.Also allows for damage free disassembly of twins and triples. No rod and crank throw impact when parts fall into a tube shaped fixture during disassembly.
Precision bearing and gear fixtures
Some of our fixtures used to remove bearings and gears. Eliminates possibility of damaging precision brass gears and Artic Cat piston ring style center seals.
