Frequently Asked Questions
How do I verify the engine application for Mahle 197843622?
Match the exact MAHLE part number and engine code, then confirm bore, stroke, rod length, pin diameter, cylinder head, compression target, and all machine-shop measurements.
Are rings, pins, and locks included with this piston kit?
Included hardware varies by exact part number. Confirm the current MAHLE package contents before assembly and do not assume components from a similar piston kit are interchangeable.
What must the machine shop measure before final assembly?
Verify finished bore, piston-to-wall clearance, ring end gaps, deck height, piston-to-valve clearance, wrist-pin fit, bearing clearances, and final compression ratio for the intended fuel and power level.
