Is a Shovelhead reliable?

If you beat on a machine it’s gonna fail you no matter what it is. If you take care of it, a Shovelhead is just as reliable as anything else. They’re easy to work on and parts are always available.

What were the AMF years for Harley Davidson?

American Machine and Foundry (AMF) bought the nearly bankrupt Harley Davidson Motorcycle Company in 1969 for an undisclosed amount of money. AMF operated the company until 1981 at which time Vaughn Beals, “Willie G.” Davidson and a group investors purchased the company back from AMF for $80 million.

Is a Shovelhead a Sportster?

Flathead, knucklehead, panhead, and in 1966, the shovelhead. Since it looked like the Sportster rocker box design, people started calling Sportsters “shovelheads”, especially after the Evo Sportster came out. I like the term Ironhead; the Shovelhead is a big twin copy of the Ironhead Sportster rocker box style.

Why is it called Harley 48?

Harley-Davidson Sportster Forty-Eight | First Ride. It’s that tiny teardrop tank that gives the Forty-Eight its name. Perhaps that’s because fitting the peanut tank meant cutting capacity from the standard Sportster’s less-than-generous 3.3 gallons to just 2.1, which many riders would find totally in-adequate. Whatever …

Why do they call it a Shovelhead?

The engine gained the nickname “Shovelhead” due to the look of the rocker heads having the appearance of an old coal shovel that was flipped upside down, giving the appearance of a shovel. …

Why did old Harleys leak oil?

Older Harley’s leak oil because its a TOTAL OIL LOSS system. Meaning the oil injected in valve system simply leaks outside engine and falls on ground. Older Harley’s leak oil because its a TOTAL OIL LOSS system. Meaning the oil injected in valve system simply leaks outside engine and falls on ground.

What replaced the Shovelhead?

It was made in the 1,340 cc (82 cu in) displacement for Harley-Davidson Big V-twins bikes, replacing the Shovelhead engine until 2000 when the last EVO was placed in a production factory custom FXR4 (FXR2 and FXR3 were the first CVOs).

Why do Shovelheads leak oil?

It is a vent for crankcase pressure. The oil is just a by product. Connecting it to the oil tank would pressurize the oil tank. There is not normally a lot of oil coming out.

Do Harleys still leak oil?

Harleys do not leak engine oil. The oil would drop off from the primary chain into the primary chaincase, which had a drain hole that allowed oil to drop to the floor.

Why do Harleys sound so good?

Harley’s engine is designed in the shape of a V and the crankshaft has only one pin, attached to both pistons. That means that both spark plugs fire simultaneously and there is a brief pause after the second fire, instead of firing at even intervals. This also accounts for the popping noises a Harley makes at idle.

Why are Harleys 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.

What does wet Sumping mean?

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’s the best oil for Harley Davidson?

Here are our top recommended the best oil for Harley Davidson V-Twin Cam:

• Best Overall: AMSOIL FULL SYNTHETIC Motorcycle Oil 20W-50.
• Runner-Up: Mobil 1 -50 V-Twin Synthetic Motorcycle Motor Oil.
• Best Budget: Castrol 06116 POWER1 V-TWIN 4T 20W-50.

What is wet sump lubrication system?

Within piston engines, a wet sump is part of a lubrication system whereby the crankcase sump is used as an integral oil reservoir. Piston engines are lubricated by oil which is pumped into various bearings, and thereafter allowed to drain to the base of the engine under gravity.

What are the disadvantages of lubricant?

Lubrication Knowledge Menu

• Poor self-healing properties.
• Poor heat dissipation.
• Higher coefficient of friction and wear than hydrodynamically lubricated bearings.
• Color associated with solids may be undesirable.
• Difficult if not impossible to feed into a lubrication system.
• Storage or service life is limited.

What are two types of lubrication systems?

There are three different types of lubrication: boundary, mixed and full film. Each type is different, but they all rely on a lubricant and the additives within the oils to protect against wear. Full-film lubrication can be broken down into two forms: hydrodynamic and elastohydrodynamic.

What is the advantage of a dry sump?

A dry sump tends to hold more oil than a wet sump in an extra reservoir, so that means it works better for sustained cornering since it’s harder to starve the engine of oil. It also allows you to mount the engine lower since it has a shallower oil pan, that improves the center of gravity.

How does dry sump oil work?

A dry sump system relies on a separate holding tank and two oil pumps. The first pump pulls the oil from the crankcase and pushes it to a remote holding tank or reservoir. A second pump sends pressurized oil from the tank to the oil galleys in the engine.

Where is oil pump located?

Oil pumps are usually either inside the oil pan and driven by a camshaft or outside the pan and driven by a crankshaft. When those engine parts start moving, the pump starts working at the same time to pump oil to reduce friction and wear between moving parts and prevent the engine from seizing.

What causes low oil pressure?

When a car’s engine pump fails, the oil pressure drops. From incorrect installation to poor oil maintenance, there can be several causes of pump failure. When engine oil pressure drops, friction between different parts increases.

What is a semi dry sump engine?

Semi-dry sump What this really means is that the system is to all intents and purposes a dry sump design, with two oil pumps, but the oil tank is still incorporated inside the engine cases.

What is a scavenge pump?

: a pump to return used oil to a tank for cooling, purification, or storage.

ARE dry sump system?

The dry-sump system uses two or more oil pumps and a separate oil reservoir, as opposed to a conventional wet-sump system, which uses only the main sump (U.S.: oil pan) below the engine and a single pump.

What is the purpose of a sump?

The sump sits below the main tank and is used as a filter, as well as a holding place of unsightly equipment such as heaters and protein skimmers. The main advantage of having a sump plumbed into an aquarium is the increase of water in the system, making it more stable and less prone to fluctuations of pH and salinity.
