The four on the bottom of the cradle mount are another story. To get to those lube
points, you must raise the gun tube. If you
forget—or just don’t go to the trouble of
raising the gun—the cradle mount bear-
ings go dry. Whenever the cannon is fired,
the tube is scored during recoil.
To protect the bearings, you’ll need to
lube
all 10
cradle mount lube points quar-
terly with molybdenum disulfide grease
(GMD) or general purpose grease (GGP).
GMD comes in a 14-oz cartridge, NSN

t’s inevitable. Lube points that are hidden or hard to reach are usually forgotten.
The cradle mount bearings on your M109A6 Paladin are a good case in point.
There are 10 lube points on the cradle mount—four inside and six outside the
vehicle. The inside lube points and the two exterior lube points on top of the cradle
mount usually get lubed regularly.

on’t be confused about who can repair what
on the A-20 Global personnel heater. Here’s the
straight scoop:
Unit-level maintenance: Limited to replace-
ment of ignitors and removal and replacement
of the entire heater.
DS/GS-level maintenance: All troubleshoot-
ing and repair with the exception of vent sensor
replacement, which is a depot-level mainte-
nance task.
Keep in mind that this heater has sensitive
electronics on board, mechanics. You must be
grounded when working on the heater. Also,
the heater should be removed or disconnected
from the vehicle before doing any welding.
TM 9-2540-207-14&P covers all heater
troubleshooting and repair procedures.
