Blade Shaft Bearing Replacement

The FS2 is supported by “tapped base lock collar (w/set screw)’ self-aligning blade shaft bearings. These heavy duty bearings support the 1-1/4 blade shaft, and have grease (zerk) points (Figures 24 and 25) conveniently located for service.

3.To loosen the tension on the three V-Belts perform the following:

λRemove the Belt Cover, item 4, page 42. (Pointers and Covers Assembly)

λLoosen the Carriage Bolts, item 11, page 40 (Engine Mount Assembly).

λLoosen the Hex Head Cap Screws, item 12, page 40 (Engine Mount Assembly).

λRotate the engine down to provide slack in the V-Belts

2.Its recommended to replace both left & right hand bearings collectively.

Replacement of the Blade Shaft Bearings

4.Perform the following to replace the blade shaft bearings:

λRemove Blade Flanges (items 7 and 8, page 38, Blade Shaft Assembly) as required to permit the Shaft Bearing(s) to slide off the Blade Shaft.

λLoosen/remove Shaft Bearing(s) Hex Head Cap Screws, item 11, page 38.

λLoosen Set Screw on the Blade Shaft Bearing collar.

λSlide “old” Bearing(s) off the Blade Shaft and replace with “new” Bearing(s)- grease (zerk) fitting pointing forward, and the lock collar oriented to the “right" as you face the saw.

5.Loosely bolt the bearing(s) into place on the saw frame, then ensure the alignment by referencing past bearing position- ing.

6.Tighten the hex head cap screw, item 11, page 38 to secure the Shaft Bearing (s) to the frame.

7.To complete the re-installation process , reverse the order of

the above mentioned steps. For V-belt adjustment, see V-belt tension section on page 23 (Figure 14).
