Description

The OTC 6691 is a camshaft retaining tool set designed for GM 2.8L, 3.0L, and 3.6L DOHC engines. This set features oversized retaining plates that lock the camshafts together at top dead center (TDC) to prevent them from turning while setting engine timing. It includes three retaining plates, with one used for tightening one set of cams and two used in conjunction for the second set.
