Components diagrams are located on the next page.
1.
Ensure bucket (I) is empty and fully lowered.
2.
Turn off and isolate energy sources, and perform in-house lock-out/tag-out procedure.
3.
Unbolt hand valve (A) from bucket (I).
4.
Remove bucket pivot pin (K) from frame pivot tubes (B) and bucket pivot tube (J).
NOTE: Remove retaining bolts to allow removal of pivot pin.
5.
Disconnect safety chain (H) from frame (D).
6.
Remove airbag pivot pin (F) from airbag bracket (E). NOTE: Remove cotter pin from either end
of airbag pivot pin to allow removal.
7.
Move bucket (I) away from frame (D) then orient bucket to allow access to rear corner (Figure 5).
8.
Mount ratchet assembly (M, N, O) as follows:
a. Locate ratchet assembly (M, N, O) on the outer rear corner of the bucket (I) as shown in
Figure 5.
b. Trace the (8) holes on the ratchet bracket (M) onto the bucket (I).
c. Center punch holes traced in previous step.
d. With 21/64" drill bit, drill clearance holes into pilot holes.
e. Using 5/16" bolts and 5/16" locknuts, fasten the ratchet assembly (M, N, O) in place.
9.
Mount ratchet gear (P) as follows:
a. Facing inside of frame (D), locate ratchet gear (P) on holes in frame—location (Q). The
ratchet gear should be oriented teeth down.
b. Install 5/16" bolts, lock washers, and flat washers (in order listed), lift ratchet gear (P) as high
as high as possible, then loosely fasten gear ratchet in place. NOTE: Permanent tightening

a. Move the bucket (I) into the inside of frame (D), and align bucket airbag pivot (L) with holes
in airbag bracket (E). Insert airbag pivot pin (F) and insert cotter pins through pivot pins.
b. Re-connect safety chain (H).
c. Insert bucket pivot pin (K) through frame and bucket pivot tubes (B), (J); then install retaining
