Timing Gear Cover
The timing gear cover is a pressed steel stamping, heavily ribbed for strength. A large cork seal is assembled into the crankshaft opening to assist the crankshaft oil thrower in preventing oil leakage around the hub of the hormonic balancer pulley. The seal is held in place in a depressed pocket in the cover by a stamped retainer. See Fig. 41. The hub of the pulley is ground to provide a smooth surface for a perfect seal.
when the balancer is installed it will not damage the oil seal. A coating of grease around the inside surface of the cork, will aid in preventing damage to the seal during this operation.

Fig. 42— Timing Gear Cover Centering Gauge
If it ever becomes necessary to replace the cork seal, the special tool, illustrated in Fig. 43, should be used. The oil seal fits over the end of this tool and can be driven into place with a few light blows of a hammer. Prick-punch or bend over lips to hold in place.

When installing a timing gear cover, it is essential that it be centered so that the harmonic balancer is installed without damage to the oil seal.
The gauge, illustrated in Fig. 42, fits over the crankshaft and, when in position, guides and holds the timing gear cover in its correct position, so
19Harmonic Balancer
This balancer consists of a small flyweight attached to and driven by the crankshaft, through non-rigid driving members. The driving members consist of four pins, carried solidly in the crankshaft pulley, which is in turn mounted rigidly on the
