echanics, when reattaching the ramp chains after maintenance, be careful where you
place the flat washers on the ramp chain connector.
Since there are two flat washers, NSN 5310-01-510-5385, you naturally assume that one
goes on each side of the connector, right? Wrong!
With a washer on each side, the connector hits and damages the pulley housing as the
ramp is closed. So, make sure you put both washers on the inside of the connector. Then
your ramp will raise and lower smoothly.

f your tank has constant problems with worn end connectors and cupped sprocket
teeth, the problem could be that you’re not coasting when it comes to adjusting track
tension.
Some crewmen think adjusting the tension means whipping out the ‘ole grease gun
and pumping grease into the track adjusting link till it comes out of the relief valve.
That’s partly right, but they’re forgetting a small but very important step.
The TM says to move the tank backward 20 feet, then forward 20 feet on a level
surface. But you need to
let it coast to a stop
before drawing your grease gun. That’s so
the track adjusting link is the only thing pressing against the track when you add grease.
If you use the brakes, the weight of the tank is thrown forward when you stop. That
leaves some track tight and other track loose. Adjusting the track then usually results in
overtightened track that wears out end connectors and cups sprockets.
So, don’t think coasting is always a bad thing when it comes to your work. In this
case, it’s the only way to go.
