How do you stop wet Sumping?

Wet sumping prevention – electrical interlock to a pressure switch in the oil line. A different approach would be to put a cut out switch at the end of the line (off the rocker feed) so that any loss of oil pressure would kill the ignition.

What does wet Sumping mean?

The term wet sumping is used to describe when oil fills the crankcase of a dry sump system. The symptoms of this is typically excessive smoking and oil coming out the engine breather tube.

What is Harley Sumping?

Sumping is when the suction side of the oil pump does not remove enough oil from the crankcase. When the flywheels rotate in the oil they turn it into an aerated state. Thus, oil gets trapped in the crankcase and does not return to pump.

What’s the difference between a wet and dry-sump?

What’s the difference between wet and dry sump oil systems? Wet sump systems tend to have significantly larger pans, with a single oil pump. Dry sump systems have shallower oil pans, with a separate reservoir and two (or more) oil pumps.

Are Harley engines dry-sump?

Harleys, you see, have dry-sump engines. That means the oil sits in a tank totally separate from the engine, usually under the seat somewhere, and is pumped in and out by an oil pump that bolts to the outside of the engine.

How long will a Harley M8 last?

The new M8 will probably be good for 200,000 miles before an overhaul, in my opinion it’s the best motor they have ever built.

What causes oil to come out of the breather on a Harley Davidson?

Top breathing engines breath, or vent, through the top breather bolts which are threaded into the heads of a Harley Davidson motor. The air inside a motor is saturated with oil. When oil drips out of an air cleaner assembly, it is usually an indication that the air cleaner element is due to be cleaned, or changed.

What is wet and dry sump and what is the main difference between the two?

Wet sump systems store the oil in the pan but a dry sump system stores it in a separate tank and pumps the pan clean leaving it essentially “dry”. The lack of oil in the pan also allows for it to be shallower which improves weight distribution and handling.

What are the advantages of a wet sump?

A wet sump offers the advantage of a simple design, using a single pump and no external reservoir. Since the sump is internal, there is no need for hoses or tubes connecting the engine to an external sump which may leak.

What’s the difference between wet and dry sump?

Are Harleys dry clutch?

Registered. Harley’s last dry clutch on a touring model was in 1984.

What does it mean when your sump is wet?

Wet sumping is when oil fills the crankcase of a dry sump system. The symptoms of this is typically excessive smoking and oil coming out the engine breather tube. There are two causes for this: Oil is not returning to the tank or oil is seeping through the pump while the engine is sitting unused.

What are the advantages and disadvantages of wet sumping?

On its way back to the tank some pressure is bled off to feed oil to the top end rockers. Advantage to this system is reduced engine size, as the oil is stored externally. Also storing the oil outside the engine means it tends to run cooler. The disadvantage is complexity.

When does oil come out of the crankcase of a dry sump system?

In a dry sump system the pump not only needs to supply oil to the engine but to return it to the tank. The term wet sumping is used to describe when oil fills the crankcase of a dry sump system. The symptoms of this is typically excessive smoking and oil coming out the engine breather tube.

What causes a Norton pump to wet sump?

In both machines worn pump bodies tend to wet sump over time. Both the BSA and Norton pumps are being reproduced in higher than factory qualities. Closer tolerances in the new production pumps eliminate wet sump issues.
