Overview – OIL PAN LOCK WASHER 915108080
The Hitachi OIL PAN LOCK WASHER 915108080 is specified for Hitachi oil-pan positions as the lock washer securing the pan fasteners and is supplied to the original dimensional and material standard.
Parts Characteristics
A lock washer that backs the oil-pan bolt, holding tension and sealing so the pan does not weep. It carries the clamp that keeps the sump tight against vibration, so a true, correct washer keeps the engine from marking its own ground.
Applicable Models & Applications
Used at Hitachi oil-pan positions specifying this lock washer. Match the size and the section against your old washer – lock washers differ in how they bite and seat.
Maintenance & Replacement
Inspect for a crushed or relaxed washer at every oil service. A washer that has given up lets the pan bolt loosen, and the loosening is what weeps the seam.
Replace the washers together with the pan gasket where the service calls for it. A new pan onto reused washers still weeps, and the weep is what stains the underside.
Confirm torque on fit so the pan rails are not distorted. An over-torqued bolt warps the pan and the gasket can never seat.
Keep common oil-pan lock washers on the bench. They cost almost nothing, they protect the sump, and a pan open on a washer is a machine waiting on a small part.
