Fill, Level Check, and Optional Temperature Sending Unit Machining
PML 14 Bolt Titan rear differential cover has a fill hole on the right side and the level check hole on the left side.
The bottom of the level check hole is at the same location as on the stock cover relative to the differential center line. PML does not recommend over filling the differential. Follow the factory instructions for fluid amount and checking the level.
Also on the right side, below the fill hole, is a boss that can be drilled and tapped for a temperature sending unit. This is optional. PML can drill and tap the hole before shipping. Select the option in the shopping cart. There is a machining charge.
Drain hole is on the bottom for easy fluid changes without removing cover. A magnetic drain plug is included.
