Factory tool number: 379246 (0379246)
Application: Front propeller shaft bearing race on Johnson 40 HP electric-shift outboard motors
Factory reference: Johnson Service Bulletin SB-922, September 26, 1962

Johnson introduced puller 379246 specifically for the front propeller shaft bearing race on 40 HP electric-shift gearcases. The earlier puller designed for the 75 HP engine could not be used for the same operation on the 40 HP model.

Factory removal procedure

  1. Remove the nut and plate from the threaded shaft.
  2. Loosen the wing nut so the sleeve can be drawn away from the puller head. This allows the puller jaws to contract.
  3. Insert the puller head into the bearing race. Tighten the wing nut to expand the jaws until they are set for pulling.
  4. Install the pressing plate and nut. Turn the nut down the threaded shaft with an appropriately sized wrench to extract the bearing race.

The factory bulletin illustrates the puller in use in Figure 2 and identifies the original net dealer price as $8.00. Johnson instructed dealers to order the tool from the Outboard Marine Corporation Parts Depot in Galesburg, Illinois, rather than from Johnson Motors or the regular parts distributor.
