S&S Cycle All-Helical Transmission Gear Set Cassettes for Harley-Davidson 1991-05 Dyna, 1991-06 FLT and Softail models, and Custom Applications - Manual (Page 16)

NOTE: If using S&S ® hydraulic clutch side cover kit PN 56-4060 follow instructions included with the kit.
22. Fill the transmission with 20-24 ounces of 90 weight gear oil or equivalent.
NOTE: S&S offers an extension for the oil filler spout on FLT models—PN 56-1292 (not included in this kit). Be sure that the flat edge is
up, directed toward the transmission side cover as shown in Picture 37. This spacer will affect the oil level reading on the dipstick due
to the increased angle resulting from the additional spacing. Typically, the full level reading on your dipstick will be
1 ⁄

normal. To verify what your new fill height will be follow the factory service manual procedures for changing your oil after installing
this transmission kit. You may want to put a notch on your dipstick indicating the new fill height.
23. Install exhaust system. Harley-Davidson ® Dyna TM models will require a clearance modification on the exhaust bracket as shown in
Pictures 38 & 39. This operation is required to clear the vehicle speed sensor boss.
NOTE: The S&S transmission gear set is .250” wider than a stock Harley-Davidson ® unit. With that in mind, you may need to shim your
exhaust mounts to allow for the extra width.
24. Use a sprocket-locking tool and specialty deep socket to install the new lightweight 34-tooth S&S pulley and tighten/torque nut
to 50 ft-lbs using red threadlock and then turn the nut an additional 35-40 degrees. Install the lockplate and torque bolts/screws
with red threadlock to 7-9 ft-lbs. Never loosen the nut to align the lockplate holes. Use the 34-tooth final drive pulley on belt-drive
models 1991-’06.
