Installation instructions S&S Twin Cam Flywheel Assembly
Note: Engines with strokes exceeding 4" may require S&S piston cooling jets and piston to jet clearance notches in the piston skirt to avoid contact.
Note: S&S crankpins allow the use of replaceable bearing races in the lower end of the connecting rods. The first generation of S&S crankpins, in use up to 2012, were 1.500" diameter. The second generation crankpins, in use since 2013, have the larger 1.671" OEM diameter crankpins. Now S&S & OEM crankpins are identical in diameter so now S&S parts can be used to rebuild stock H-D flywheels, something that previously was not possible since H-D rebuild parts were, and are, not available.
Note: Following is regarding 03-17 models. S&S has designed these flywheels to work with a Timken style sprocket shaft bearing, they will fit stock 99-02 model year and all S&S cases without modifications. Stock H-D 03-17 Twin Cam engines use the same sprocket shaft roller bearing as is used on the pinion shaft, a cost saving but weaker solution. It is possible to use the stock weak 03-17 sprocket shaft bearing kit (OEM H-D 24004-03B) with S&S flywheels in 03-17 stock cases. However, S&S feels this roller bearing will not take the side loads produced in a high performance motor. S&S will not honor any warranty claims in an application where the OEM 24004-03B/24605-07 03-17 sprocket shaft roller bearing style bearing assembly is used. To upgrade to the pre-2003 style sprocket shaft bearing A517-880922 JIMS conversion tool kit is available. This kit includes a tool, a Timken bearing and a steel crankcase bearing insert for one motor. Bearing inserts only are available as A519-880924, bearings only as A960-411365.
Note for:

- 07-15 Softail with OEM 96/103/110" pistons & OEM sprocket shaft bearing (4-3/8" stroke)
These S&S connecting rods have a non Timken pressed-on sprocket shaft roller bearing race for use with the stock 24004-03B sprocket shaft bearing, a weaker solution but it is compatible with OEM components. Complete with tapered wrist pin ends that are compatible with stock H-D pistons.
