A: Deep concentric scratch rings across the sealing tracks, faded bronze coloring from severe overheating, or micro-pitting erosion around the high-pressure relief slots require the component to be replaced.
A: Mechanics must align the plate cleanly over the indexing dowel pin in the rear block cover. Misaligning or swapping the plate layout will reverse the oil flow direction, destroying the internal rotating group upon engine startup.
A: This part number is configured specifically for the right-hand rotation pump group. Re-checking your internal component orientation with our technical catalog ensures a correct match before finalizing your order.
A: The alloy steel backing plate undergoes deep thermal conditioning to increase its resistance to pressure fatigue. This keeps the timing surface flat and true, even under the intense pressure spikes common during continuous rock breaking shifts.
