BEFORE YOU BEGIN
The transmission is a component in the powertrain of your motorcycle. As such, it’s function is
highly dependent on other components in the powertrain to perform as designed. If the clutch,
clutch actuator, primary, or shift linkage is worn, tired, or compromised in any way, the
transmission will not perform as designed. The process of installing the GrudgeBox is the
perfect time to assess and freshen up these components to ensure the transmission gives you
years of trouble-free service.

STOCK COMPONENT REMOVAL
Refer to your Factory Service Manual for detailed instructions on how to remove your stock
gearset, main drive gear, shifter pawl, and speed sensor from the transmission case. Softails,
Dynas, and Touring models are all different configurations and require different methods to
accomplish the removal. Ensure that you have the correct Factory Service Manual for your year
and model of motorcycle.
BERT TIPS:
Apply heat to the comp sprocket bolt head prior to removal. Failure to do so could result
in mangled sprocket shaft threads and halt the installation of your GrudgeBox.
Remove the dipstick prior to removing the gearset from the transmission case. Failure to
do so will result in a broken dipstick and a trip to the nearest H-D dealer.
