uring recovery operations, the M88A2’s three snatch blocks can be your best friends
or your worst enemies. And a few squirts of GAA are what makes the difference.
The 6.5-, 35- and 140-ton snatch blocks are designed to turn freely to center out
the load. If they can’t because of a lack of lube, the winch cables can twist and
be damaged.
The snatch blocks aren’t lubed according to any set interval, but they should be
lubed after fording and after operation in mud or heavy dust.
The 35-ton snatch block
is on top of the vehicle
in the boom tray. Pump
GAA through the grease
Ftting until clean grease
is visible. Wipe off the
excess grease.
You’ll Fnd the 140-ton snatch block
stored in a bracket on the right side of
the vehicle. Remove the pin at the top of
the snatch block and lube it with GAA.
The grease Ftting is located on the inside
bottom of the snatch block. Pump in
GAA until you see clean grease coming
out. Then wipe off the excess.
