Installation Instructions For Differential Covers

PML recommends RTV by Permatex for use sealing PML differential covers. RTV is readily available at most auto parts stores.

Permatex 26B High Temp RTV for temperature ranges -75F through 650F
Permatex 27B High Temp Sensor Safe RTV for temperature ranges -75F through 650F
Permatex 6B Sensor Safe Blue RTV for temperature ranges -65F through 500F

For temperature sensors, PML recommends Autometer products. See www.autometer.com.

Fill plugs on most PML differential covers are 1/2 NPT pip plugs and these use a 3/8 inch allen wrench.

There are a few differential covers which do not yet have installation instructions on-line. Please call or email if you do not see the instructions for your differential cover.
