SUBJECT: #379238 TORQUE SHAFT - for 10 h.p. propellers
    as used on models QD-19 thru 24.

Due to an oversight in designing Propeller Torque Fixture Assembly #378448, the torque shaft for checking hub slippage on 10 h.p. propellers (models QD-19 thru 24) was omitted. Here then is a suitable torque shaft designed to check these 10 h.p. propellers.

#379238 Torque Shaft

When using this shaft insert it in fixture - hex end up. The lower pin will prevent the shaft from dropping too far into the fixture, assuring engagement of the upper pin with the propeller hub. Place the propeller on the torque shaft, adjusting the three propeller stops to anchor the propeller.

Use the appropriate size six point socket and torque wrench to check for slippage - torque specifications for Johnson propellers are listed on Service Bulletin #881.

This new torque shaft will not be included in the propeller torque fixture assembly until after October 1, 1962. After that time it will no longer be necessary to place a special order for the 10 h.p. torque shaft when the complete Propeller Torque Fixture Assembly, #378448, is ordered.

The net price of #379238 Torque Shaft is $2.50.

C.O.D. orders are unacceptable. Mail all orders with prepayments, check or money order, directly to: OUTBOARD MARINE CORPORATION PARTS DEPOT, P.O. BOX 470, GALESBURG, ILL. Do not order from Parts Distributor nor Johnson Motors.
