GASKET KITS AND MOUNTING PARTS
Use the proper quantity of gaskets as SHIMS to provide the best running
condition of the power take-off. If the installation is TOO TIGHT—add gaskets, if
TOO LOOSE—remove gaskets.
To facilitate handling, popular size gaskets are supplied in kits.
One or more gaskets (as required) must always be used between the metal
surfaces of the power take-off, adapter gear assembly, adapter plate, and filler
block or blocks.
The 13M13541 gasket is recommended for all Allison transmissions using U60
gear designators.
Refer to the PTO operator’s manual, supplied with the PTO, for more detailed
installation information.
Gaskets which are .010” in thickness generally affect backlash by .006”. Gaskets
which are .020” in thickness generally affect backlash by .012”.
