4. Remove lift arm components as necessary using
Figures 21 and 23 as guides.
NOTE: If pull link assembly (item 27) removal is neces-
sary, refer to Cutting Deck Pull Links in the Service and
Repairs section of Chapter 7 – Cutting Deck.
Assembly (Fig. 21)
1. Check flange bushing(s) in carrier frame for wear or
damage (Fig. 24). Replace flange bushing(s) if neces-
sary.
2. Install lift arm components as necessary using Fig-
ures 21 and 23 as guides.
A. If rear lift arm was removed from deck lift shaft,
make sure to thoroughly clean tapers of shaft and lift
arm bore before installing lift arm to shaft. Also, when
installing washer (item 26), position washer cavity to-
ward lift arm (Fig. 25).
B. If ball joints were removed from link (item 13),
install ball joints equally on both ends of link. Adjust
center to center length of link assembly from 18.070”
to 18.180” (45.9 to 46.1 cm) (Fig. 26). Tighten jam
nuts to secure ball joints to link. Make sure that ball
joints stay inline when tightening jam nuts.
NOTE: Do not change the link assembly length to
adjust the height–of–cut or for any other reason.
NOTE: When properly installed, flange nuts (item
23) should have flange surface against lift arm and
not against chain.
C. If cap screw (item 20) was removed from chain
(item 22), insert screw into upper link of chain and
thread flange nut (item 23) onto screw with flange
away from link. Torque flange nut to 50 ft–lb (67
N–m). When fastening chain to front lift arm, torque
second flange nut to 50 ft–lb (67 N–m). When instal-
ling chain to rear lift arm, torque cap screw to 50 ft–lb
(67 N–m).
3. Lubricate all lift arm grease fittings after assembly.
4. Start engine and fully raise cutting deck. Stop engine
and remove key from the ignition switch. Install HOC pin
into HOC bracket to allow desired height–of–cut (Fig.
22).
