A lack of lube in the
tower area causes too much
strain
on
the
cylinders
and rods that angle the
blade. For smooth blade
movement, remember to
wipe off the ±ttings before
you start lubing. That way
no grit is pumped into the
rod’s bearings.
When you lube, pump grease into each ±tting until you see clean grease oozing
out. Four to ±ve pumps should do it. Lube these ±ttings once a week like it says on
Page 126 of TM 5-2430-200-10.
With
your
grease
gun handy, lube these
lift cylinder ±ttings as
well for smooth blade
operation. You’ll ±nd
‘em on each side of
the
vehicle,
behind
the blade next to the
track.
S
everal energy chains on the dry support bridge (DSB) protect the vehicle system’s
hydraulic hoses. Plastic links connect with one another to form each chain. They’re
designed to surround and flex with hydraulic hoses.
During travel or bridge
construction,
the
chain
links can get damaged or
disconnected. And step-
ping in the wrong place
can break the chain link!
When a chain gets dis-
connected, realign and re-
assemble the links if possi-
ble. Remove any damaged
links and use duct tape or
heavy-duty water-resistant
tape to hold the broken
links or halves of the chain
together. This is a quick Fx
to keep you in operation
until new links, found in
TM 5-5420-279-23P, can be
ordered.
Do not replace the entire chain when a few links are damaged. Individual links are
expensive, and the whole chain runs about eight times as much.
You’ll Fnd the assembly procedures for the chain links starting on Page 5-305 of
TM 5-5420-279-23.
Cab Tilt Pin ±ittings
Taking a few steps back (with
your grease gun still in hand) puts
you next to the cab tilt pin’s grease
±ttings. There’s one on each side of
the vehicle directly under the cab
and above the track.
Lube puts slide and glide into the
cab tilt pins when the cab is tilted
up or down. Give each ±tting four
to ±ve pumps of grease every three
months like it says on Page 127 of
the -10 TM.
Here’s what to lube:
1. angle cylinder rod end
2. angle cylinder head end
3. single-tree upper
4. single-tree lower
