Ron’s Tip: Damaged Fasteners
This tip comes from our Shop foreman, Ron Quinlan. It’s a great method for removing the nut from badly damaged threads of a bolt when you’re out on the fishing grounds and have to keep things going: Often a rusted nut has been seized in place by rust for years. What if the alternator is bad and you have to put on the spare, but the bolt threads are damaged? The nut needs to be back-off of the damaged threads, but how to do it? If it looks badly rusted or the bolt threads are damaged, before even trying, Ron first 
coats the damaged threads with never-seize compound, a special lubricant made of grease and graphite particles. With a good effort the nut can be turned through the damage and off of the bolt. In a pinch, a stream of penetrating oil will also sometimes work. Be sure to carry marine grade Anti-Seize compound on the boat. It is also known as NEVER-SEIZE.
Avoid Fast Track To Engine Failure
There is no faster way to get your engines’ picture on this page, than to install a new John Deere engine without a functional pressurized cooling system. Guaranteed!! Without a pressure cap coolant wil evaporate, the level will get low and the engine will overheat. When evaporation occurs minerals concentrate throughout the cooling system, hindering heat transfer. Water also boils at a lower temperature without a pressure cap, and far more aeration occurs.
If your expansion tank has lasted several years, then clean it thoroughly and install one of our Part Number:RE-46165 cap adapter. This adapter can be bolted to any tank. Gary, Norm, or Ben Cline, in parts can be reached at 800-777-0714.
Hose Failure Due To Electrolysis
Coolant hoses-Not only is is important to use coolant conditioner in the engine, but be sure to also periodically inspect coolant hoses for damage. Coolant conditioner stops electrical activity in the coolant that harms metal-such as wet cylinder liners, and also coolant hoses!
This large Cat failed after turning too fast. Approximately 100 pounds of metal shrapnel were found in the oil pan.
Caterpillar Over-speed
This red exhaust port is the sign of an upcoming engine failure. Water enters an exhaust manifold one of two ways: From the cylinders’ exhaust valve port, or from rain or swamping entering the outlet end of the manifold.
Beware Of Red Exhaust Manifold Ports
