Installation Tips

Phosphate coating provides the grey appearance to the Mahle piston. This dry lubricant coating (not to be confused with a thermal film coating) provides a lubricant film in the pin bores and ring grooves until the oiling system of the engine reaches operating pressure; particularly useful during the initial start-up or break-in of engines to protect against galling and microwelding. The piston crown is still machineable.
The location to measure piston-to-wall clearance for each application. This point is calculated from the bottom of the piston skirt and indicates the widest part of the piston and thus where to measure.

Comp Height: 1.550"
Pin Diameter: .927"
Clearance Guide:
Meas. = 0.894
Min = 0.0025
Max = 0.0033
