VIEW FROM UNDER THE MACHINE, EARLIER MACHINES ONLY Steps 1 and 2 are for earlier machines only that do not have the pivot shaft tube between the frame.1. Remove bolts (1) and slide retainer (2) toward the center of the machine on each side of the frame.
VIEW FROM UNDER THE MACHINE, EARLIER MACHINES ONLY2. Remove split shims (3) from each side of the frame. Put identification on the shims for correct installation. 3. Install tooling (A) on the end of the pivot shaft. Install a 5/8"-11 NC forged eyebolt in the end of the pivot shaft. Fasten a hoist to tooling (A). With a lift truck or a similar machine pull the pivot shaft out. As the pivot shaft is removed, fasten another hoist as shown to the pivot shaft to hold it in balance when it is removed. Remove pivot shaft (4). The weight of the pivot shaft is 1960 lb. (887 kg). Steps 4 and 5 are for earlier machines only that do not have the pivot shaft tube between the frame.
EARLIER MACHINES ONLY4. While pivot shaft (4) is removed, remove retainers (2) from the pivot shaft.
EARLIER MACHINES ONLY5. Remove adapters (5) and chevron seals from each side of the frame.
Do not remove bushings (6) unless a replacement is needed.
6. Remove bushings (6) from each side of the frame.Install Pivot Shaft
1. Lower the temperature of the bushing. Install the bushing in each side of the frame with tooling (A). Steps 2 through 6 are for earlier machines that do not have the pivot shaft tube between the frame.
EARLIER MACHINES ONLY
EARLIER MACHINES ONLY2. Install adapter (V), chevron seals (W), (X), (Y) and adapter (Z) in the frame with the sequence shown in illustration 80242x1.3. Put the split (opening) of each seal and adapter at the position shown in illustration A80243x1. Put lubricant that is to be sealed on the lips of the seals and adapters.4. Install original shims (1). Install retainers (2) with the small diameter flange toward the frame seal bore. Start the bolts that hold retainer (2) in place just enough to hold the chevron seals in place. Make sure that there is no force against the adapters or chevron seals.6. Do Steps 2 through 4 for the other side. 7. Install tooling (B) on the end of pivot shaft (3).8. Put 5P960 Multipurpose Type Grease on the pivot shaft and pivot shaft bushings.9. Fasten a hoist to the pivot shaft as shown. Slide the pivot shaft through one side of the frame. 10. Put tooling (D) in position as a support for the pivot shaft. Make an adjustment to the hoist and slide the pivot shaft in the frame. 11. Install a 5/8"-11 NC forged eyebolt (4) in the frame. Install tooling (C) as shown. Use tooling (C) to make distances (X) and (Y) the same length. This is the distance from the end of the pivot shaft to the frame. The correct distance for
