S&S Cycle All-Helical Transmission Complete Assembly for 1991-99 Harley-Davidson Softail and Custom Applications - Manual (Page 7)

3- Transfer the breather hose from the stock unit to the S&S ® transmission.
4- Connect the neutral switch wires to the neutral switch as shown in Picture 7. If you are working on a 1991-1997 Harley-Davidson ® ,
you will need to convert it to a two-wire system with H-D ® part numbers, 72405-98TN and 72405-98BK (not included in kit). See
Picture 8.
Convert the wiring by following the procedure below:
A- Cut the existing single pin connector off and splice the tan wire in its place.
B- Connect the black and tan wires to the neutral switch. Attach the end of the black wire to a suitable ground using an eyelet
or equivalent solderless connector.
5- Loosely install the starter, oil tank and battery per the factory service manual. DO NOT CONNECT THE BATTERY CABLES AT THIS
TIME. You will need to tighten the starter mounting bolts later in the procedure.
6- Position the drive belt over the S&S ® 34-tooth pulley. This may require removing the rear axle to allow enough slack in the belt to
fit over the pulley.
NOTE: Use of the stock 32-tooth pulley with the S&S transmission will result in an extremely low overall first gear ratio. S&S provides a
34-tooth pulley to counter-act the lower internal first gear ratio by changing the final drive ratio with the provided pulley.
7- Use the S&S inner primary bearing race installation tool PN 56-5141 to press the race from the old transmission mainshaft onto the
new mainshaft as shown in Picture 9. When using the stock H-D
® bearing race, press race onto shaft so inside edge is 0.100” from
main drive gear.
NOTE: S&S recommends the use of S&S race, part number 56-5089, to eliminate race movement on the mainshaft—preventing damage
to the output gear seal.
