Here are two tools designed to remove and install the new driveshaft support needle bearing, which is original equipment on 1962 - 40 h.p. engines. This needle bearing (anti-friction type) is located near the top of the upper gearcase and replaces the floating bronze bushing which was previously used in this application. The new needle bearing and bronze bushing are however, not interchangeable.

These tools are also for use when repairing a replacement gearcase on 35 or 40 h.p. motors (1958 through 1961) in the event the replacement gearcase contains this new needle bearing.

Proper use of these tools is explained here.

(a) #309916 REMOVER - Upper gearcase bearing.

  1. Invert gearcase placing it on 2 blocks of wood as shown in (figure 1).
  2. Insert the REMOVER and drive bearing and seal simultaneously using rawhide mallet.

(b) #309915 INSTALLER - Upper gearcase bearing.

  1. Place bearing in position for installing DRIVE AGAINST LETTERED SIDE ONLY.
  2. Using INSTALLER #309915 and driver handle #378737 - drive bearing into position using rawhide mallet. Install so that second step of tool #309915 is in contact with gearcase (Figure 2).
  3. Install seal - flush with top of recess.

IMPORTANT: It is essential that tool #309915 be used to install the driveshaft support bearing. Use of the INSTALLER as described above locates the bearing in the correct position to assure proper contact of bearing with chrome plated band on driveshaft.
