Description
Premium aftermarket replacement oil pan from PAI Industries. The 841202 is a steel rear-sump pan with a silver EDC finish, 36 quart capacity and 12.05 in overall depth, and it ships with the M20 x 1.5 drain plug installed. It replaces Mack 240GB5263M5 on E7, E-Tech and ASET 12L engines.
Signs You Need a New Oil Pan
- Oil dripping or pooling from the lowest point of the engine, heaviest right after shutdown, with a wet film tracking along the pan rail or drain boss
- Visible impact damage — a dent, crease or gouge from road debris, a curb strike or bottoming out
- Stripped or leaking drain plug threads that a new sealing washer will not stop
- Rust-through, pinholes or weeping at the lowest seam or drain boss, common in road-salt regions
- Pan flange no longer flat, with elongated bolt holes, so a fresh gasket starts leaking again within days

Verify fitment with your VIN or engine serial number and configuration before ordering. Mack built three pans in this family and they are not interchangeable: 240GB5263M5 is this pan at 12.05 in deep with 6 ports; 240GB5263M7 is PAI 841203 at 11.50 in deep with 1 port; and 240GB5263M6 is PAI EOP-2045E. Confirm which one is on your engine before ordering. Gasket is not confirmed to be included — order the pan gasket separately unless verified.
