Unduly thrifty; niggardly. lube means your tank turret's race ring assembly will soon come to a grinding halt. Why? Sometimes the race ring just doesn't get lubed monthly like it's supposed to. At other times, grease gets washed away and dirt is forced in when high pressure water or steam is used for cleaning. No matter what the reason, too much dirt or too little lube leads to damage to the springs, ball bearings ball bearings n → roulement m à billes and the race ring itself. Pretty soon, your tank is out of commission. Ball Bearing Race Ring 1.

Look for contamination unserviceable grease, damaged ball bearings and damaged or turned springs. 2. Reinstall To go through the installation process once again, because files have become corrupted. See reload. the ball insert plug and traverse the race ring 90[degrees]. Never traverse the turret without the plug in place or the springs will jam up and the bearings will fall out. 3. Remove the plug at the new position and inspect again. Continue until you've inspected the race ring at four separate 90[degrees] positions. Reinstall the plug after the final inspection. If you find any contamination or damage, tell your mechanic. He'll contact support maintenance so they can perform the race assembly ball and spring replacement procedure listed in the -34-2-2 TMs. One more thing: Make sure the ball insert plug that comes with your tank, stays with your tank. The race ring assembly and ball insert plug are a matched set and have to stay together. Wire Race Ring There are no inspection criteria for tanks equipped with the wire race ring, NSN 1015-01-433-7999. You'll still need to lube it monthly, though. Trouble is, those race rings don't have easy access to the lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of fittings. The harder the fittings are to reach, the less likely they are to be lubed. With your unit commander's permission, you can now fix that problem by having your mechanic install a modified shield and guard with new lube fittings. The modification makes lubing the race ring during PMCS PMCS PMC Sierra (stock symbol) PMCS Project Management Control System PMCS partial mission-capable, supply (US DoD) PMCS Preventive Maintenance Checks & Services PMCS Professional Military Comptroller School much easier. For detailed instructions on how to install the modified shield and guard, contact TACOM-Rock Island's Steve Stroyan at DSN DSN - Digital Switched Network 793-2777 or (309) 782-2777.
