(2) Attach a chain hoist to the carriage and raise

slightly to relieve tension on the chains.

(3) Refer to figure 3-67 and remove cotter pins

and chain links securing chains to carriage.

(4) Refer to figure 3-68 and remove cotter pins

and chain links from chain anchors attached to the

cluster cylinder. Lift chains over chain bearings and

off of cross head and remove chains from mast.

c. Cleaning and Inspection.

(1) Clean chains with cleaning compound, sol-

vent (Spec. P-S-661) and dry thoroughly.

(2) Inspect chains for bent, cracked, or damaged

links. Replace defective links.

(3) Lubricate chains with oil (OE).

d. Installation.

(1) Refer to figure 3-68 and place chains through

cross heads and around chain bearings.

(2) Connect chains to chain anchors with chain

links and cotter pins.

(3) Lower other ends of chains to anchors on car-

riage (fig. 3-67) and attach chains to anchors with

chain links and cotter pins.

(4) Operate lift mechanism and check chains for

binding on uneven operation. If cylinder cluster is

fully retracted, carriage should be level and forks

should not touch floor. Refer to e below to adjust

chains.

e. Chain Adjustment.

(1) Check to see that mast is in a vertical position

and that cylinder cluster is fully retracted.

(2) Loosen locknuts and adjusting nuts (fig. 3-68)

on the chain anchors.

(3) Turn the adjusting nuts to vary chain length.

Tighten or loosen the chains until the chains are a

snug fit and forks barely clear the floor.

(4) Tension must be equal on both chains and

carriage must be level.

(5) Tighten locknuts. Check adjustment to see it

has not been disturbed.

(6) Operate lift mechanism and check chain

operation.

(7) Lower carriage and fully retract cylinder

cluster. Check for carriage level and forks clearing

floor.
