What happens when chain is run through oil bath?
Having long sections of chain run through the oil bath can cause oil foaming and overheating. In slinger disk lubrication, a rotating disk picks up oil in the bottom of the casing and slings it against a collector plate.
What happens when chain is not properly lubricated?
Even if overall chain life is acceptable, lack of proper lubrication can cause other problems. When a chain is starved for lubrication, wear from one joint to another can vary greatly, causing erratic action. Rapid joint wear can cause early loss of timing in a conveyor.
What causes extra load on the timing chain?
The wrong oil can cause extra load on the chain and the engine will not be properly lubricated. Each vehicle manufacturer specifies a minimum API oil service rating, a recommended viscosity, and often a specific oil.
What’s the best way to lubricate a chain drive?
The recommended method of lubrication for chain drives is indicated in the power rating tables published in ASME B29 Series Standards and in various manufacturers’ catalogs. The methods normally listed are manual, drip, oil bath, slinger disk and oil stream.
What causes oil to separate from the timing chain?
Over time, oil begins to separate as it heats up and is exposed to natural solvents found in gasoline. If the timing chain begins to wear out, small metal pieces can break off the chain and find their way into the oil pan.
What was the name of the oil rig that sank in 1979?
Bohai Number 2 Oil rig was built in 1969 by Mitsubishi and sold to China in 1973. It was one of the oldest rig owned by China. It sank on November 25, 1979 in Gulf of Bohai which is between China and Korea. The accident killed 72 people aboard. The accident was caused by strong winds while the rig was towed.

How did the Usumacinta oil rig accident happen?
Usumacinta was a Jack-up rig. It was positioned next to Kab-101 platform to complete the drilling of well Kab-103. Strong winds of 130 km/h and waves up to 8 meters in height caused the cantilever deck to hit production tree of Kab-103.
