Timing Gear Cover No. 2, 1HDT & 1HZ (early) - 11322-17010

Timing Gear Cover No. 2, 1PZ, 1HDT & 1HZ (early)

This is the outer timing gear cover.

When or why this part needs to be replaced: The injection pump drive gear bearing is subject to wearing this timing case where the bearing press fits into the casing.

If this wear is evident, in the casing where the bearing sits, during your rebuild then you should seriously consider replacing this part. If the bearing is loose in the housing, the injection pump shaft will not be supported in a concentric manner with the timing gear and timing belt drive pulley, causing rapid failure of the injection pump drive (input) shaft bushing, which leads to injection pump failure...
