Removal and Installation of Load Chain
LINK CHAIN HOISTS - A new chain should never be used on a worn pocketwheel. Replace chain and pocket-wheel
as a pair. To remove chain; disconnect end of load chain from anchor lug on housing by removing screw (Y157-51)
and washer (Y13-4-C).
Note: Models with a chain basket, remove chain stop from end of chain. Chain can be pulled through housing by
hand while holding brake open, by pulling (or pushing) on control arm (either end). On 1 ton models,
disconnect opposite end of load chain from anchor bracket (41624) by removing nut (Y109-524) and bolt
(41625). Remove chain stop and lower hook assembly.
ROLLER CHAIN MODELS - Disconnect end of load chain from anchor block (44686) by removing connecting link
(33363).
Note: Models with a chain basket, remove chain stop (ring) from end of chain. Chain can be pulled through housing
by hand while holding brake open, by pulling (or pushing) on control arm (either end). On 1 ton models,
disconnect opposite end of load chain from anchor bracket (37579) by removing bolt (37580) and anchor pin
(34316). Remove chain stop and lower hook assembly.
Installation
LINK CHAIN MODELS - Position hoist in a vise or other suitable holding device
cap, brake spring and brake shoes, Turn brake wheel by hand to rotate pocketwheel while carefully feeding chain
through chain guide and around pocketwheel. Pull sufficient chain through housing to allow end link of chain to be
attached to anchor lug on housing.
IMPORTANT NOTICE: The link chain must be positioned around the pocketwheel so the weld on the standing links
of chain face outward from pocketwheel
pocketwheel so it will be positioned properly to permit attaching chain to anchor lug on housing without twisting
of chain
(Figure 19, p.
26).
!
DO NOT attempt to feed chain over pocketwheel or sprocket by air power as chain will be pulled
through at a very fast rate.
ROLLER CHAIN MODELS - Remove housing cap, brake spring and brake shoes. Turn brake wheel by hand to rotate
sprocket while carefully feeding chain through guide and around sprocket. Pull sufficient chain through housing to
allow end link of chain to be attached to anchor block and anchor lug on housing.
To assemble chain to lower block on 1-TON models, refer to
