V-Twin Motor Shop Twin Cam Flywheel Remanufacturing Services
Flywheel that are out of round or scissored can be repaired. The new flywheels
on the 1999-up Big Twin are pressed together, but no match for our V-Twin Motor
Shop. We will press apart and disassemble this style wheel assembly, inspect
shafts, and crank pin components. V-Twin Motor Shop will rebuild your Twin Cam
flywheel assembly to OEM specification using new bearings, crank pin and solid
plugs, then balance and true. We can also weld the pin and plugs, if requested,
at the flywheel and crank pin interface, for rigid power. We stock the bearings,
cages and oversize crank pins to provide you with the components at hand when
your flywheel arrives. We will hone the rods to allow the oversize pin to be fitted
as required. Flywheel set will be trued and balanced. The final assembly and
press is complete in our dedicated TC-88 flywheel fixture assembly.

S&S Twin Cam 3 Piece Flywheel Assemblies feature heat-treat-
ed 4140 material that is 114% stronger than stock. Larger 1.671”
crankpin for increased crank-pin clamping force. Integral main-
shafts eliminates two potential points of weakness. Reduced main-
shaft deflection at high rpm, less vibration, reduced piston and rod
side thrusting, prevents oil pump damage, fully compatible with
gear drive cams. 2007-up stock rod length is 7.659”. Stock pistons
in 2007 and later engines require rods with tapered wristpin ends.
Note: Flywheel assemblies supplied with sprocket shaft bearing
race installed are compatible with stock roller style sprocket shaft
bearings. Assemblies with no race require a Timken sprocket shaft
bearing.
V-Twin can provide quality professional machine shop and engine
building service through a Motorshop. We can handle any job from
fitting a set of pistons in your cylinder to complete rebuild of any
engine. Contact your V-Twin customer representative for details.
