4-5/8″ stroke with 8-1/2″ diameter flywheels. Balanced to 1035 grams total piston weight. Stock replacement for S&S engines. custom for OEM engines. No hassle in rebuilding or getting the right parts. it’s all here in one package. These are exactly set-up like the flywheels used in current S&S production engines. Note: Engines with strokes exceeding 4″ may require S&S piston oiling 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 MCS 978517 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 978519. bearings only as 508960. Note: In any and all applications the technician must be able to judge components for their suitability in combination with the other engine components. prior to installation. It is of importance that a knowledgeable mechanic will install & make adjustments as required.99-06 Twin Cam (excl. 2006 Dyna) Stock replacement for S&S T124/T116 engines
