  Failed Floating Face Seal   When a Caterpillar excavator chain drive motor (such as a Caterpillar 303CR) comes to the shop for repair or overhaul, the problem is usually due to a leak on the back of the sprocket and hydraulic motor. This particular leak is caused by the failure of a mechanical seal (also known as a double cone or face seal). This special seal keeps the transmission oil on the planetary side of the transmission. When the front seal fails, two things happen: (1) gear oil starts to leak, and (2) dirt starts to get into the hub.   Gear oil leak   Gear oil flows between the gears and the final drive. If a leak occurs, the transmission fluid usually needs to be topped up. It's a temporary fix, but you can't make it permanent. If the seals continue to wear, the leak will get worse and you may be running the final drive without gear oil. The loss caused by downtime is far greater than the loss caused by replacing the mechanical seal.   C ontaminated g...

 A brand new diesel engine loses gasoline when running at full load. A burst occurs when diesel, air, or steam enters the crankcase through the ring. The correct pressure must be maintained in the cylinder chamber for proper combustion. In modern diesel engines, it takes time for the rings to seat properly and forms a tight seal. After a short break under load, the spraying problem will resolve itself. Therefore, a properly functioning diesel engine should not emit smoke from its exhaust. Smoke from the vents could be a symptom of a more serious engine problem. This article will help you diagnose the root cause of diesel engine smoke.   Diesel Engine Smoke damage appears in three colors: white, black, and blue. Persistent exhaust fumes may present a deeper internal engine problem. Airflow like a turbo is delayed until the amount of diesel injected into the cylinders is increased to a similar level, so it can withstand small amounts of smoke from older diesel engines under high...

  What is a cylinder liner and what is the engine cylinder liner function? I believe that many people who have encountered engine problems have such questions. Is the cylinder liner necessary for the engine, and what role does the cylinder liner play in the working process of the engine, the following will answer you one by one.   What is Cylinder Liner? It is a cylinder installed on the engine body to form a cylinder, a sleeve in which the piston of the engine reciprocates, and one of the key functional components that constitute the interior of the engine. They are often referred to as cylinder liners.   Due to the high-speed sliding of pistons and piston rings, the cylinder walls in an engine are often exposed to high temperatures and pressures during operation. Especially the engine cylinder liners of trucks and excavators need a longer service life, so the cylinder liners with excellent wear resistance are the key to affecting the engine life.   Materials used i...
