I need a new umbrella for my large Cantilever Umbrella where do I get it and how do i fit it

There are many umbrellas available in the market to cope up with strong winds. There's almost nothing more frustrating than walking through a storm and having your umbrella turned inside-out and destroyed by a strong gust of wind. Many umbrellas experience breakage in this way, leaving their owners exposed to the elements. To have more options you can look on Travel Umbrella.

Harley Evo blowing oil through air filter. Isn't

Well, there is an "umbrella valve" in each of the center sections of the rocker box. These can and do get brittle from the repeated heating and cooling. They do a good job of keeping the bulk of oil out of the air filter but they can't get it all. As will all previous Harleys, they blow a bit of oil and those that relieve their crankcase pressure into the air filter do still make a mess that must be cleaned out occasionally. But, it shouldn't be excessive. Excessive blowby on the rings can exaggerate the problem.

To replace the "umbrella valves", simply take the bolts out of the rocker box cover and replace the gaskets and the valve. You will have to pull the fuel tanks to do this job.

Good Luck

My02 sportster xl1200c is building up pressure incrankcase, i can tell by removing oil dipstick it releases pressure. what would cause this?

Your crankcase pressure is supposed to be vented though the heads. Take your air filter cover and the air filter off. The backing plate is held on by three small screws and two large bolts. These two large bolts are hollow and the vent the crankcase into the air filter as per EPA regulations. Check these and make sure they're open.

Now, this pressure gets to the breater tubes though an umbrella valve in the center section of the rocker box cover. This umbrella could have become brittle and flexing as it should be but I've never seen this.

Check the two large bolts and make sure someone hasn't closed these off to keep oil of the air filter. This is common if someone has changed the air filter assembly.

Good Luck

On my way home my bike strated leaking oil for the air cleaner. Wha en I took off the air cleaner it had oil in it but I don't see where it is coming from. What could be the cause of this ?

Since 1994, Harley engines have been called "head breathers". This means that the crankcase overpressure is vented through the head where in years past, it was vent out of the crankcase down lower on the engine. The EPA made Harley change the crankcase ventilation system so that any overpressure was rerouted through the engine via the carburetor instead of simply being blown out on the ground.

If you'll look behing your breather, you'll two large bolts that screw in the heads, one into each head. These bolts are hollow and the crankcase pressure is relieved through these bolts directly into the breather.

If you're getting some oil in the air filter, this is normal. But, if you're a LOT of oil in the breather, you have either overfilled the oil tank or the "umbrella valves" in the center rocker box section may be bad. Since these "umbrella valves" are made of a rubber type substance, heat and age make them become hard and brittle. When this happens, they don't function as they should.

They're not difficult to replace. Simply take the tanks off your bike and take the six screws out of the rocker box cover. Lift the top and center section off. You'll see the umbrella valve at the inner right corner of the center section. Pull the old one out and pull the new in just like the old one was in there. Put the rocker box cover back on and do the rear one. Put the tanks back on the bike. No problem.

Good Luck

Oil blowing out throttle body on filter and blowing down the side of bike. I had a new crankcase breather valve kit installed one month ago. It was fine until two days ago. All o-rings were replaced also.

The oil may not be coming out of the throttle body. The crankcase breather system is actually in the rocker box covers. Yes, there is a breather gear in the crankcase but that is for the oil return to the oil pump.

The crankcase ventilation system vents crankcase pressure into the air cleaner as required by the EPA. The purpose is to route oil mist contained in the crankcase ari that is vented into the engine to be burned. There are 'umbrella valves" in the center section of the rocker boxes. Over time, the heat makes these pieces get hard and brittle since they are made of a type of rubber. When this happens, they don't stop the oil mist as well as they used to. The oil mist is blown into the air filter where it coaleses into drops of oil. This is normal for any Harley due to their engine design.

But, if it's too bad, I'd suggest replacing the umbrella valves. Simply remove the top and center section of the rocker boxes by removing the six bolts that hold the parts on the top of each cylinder. Replace the umbrella and the edge gaskets and replace the covers. Torque the bolts to 10-13 foot pounds.

Good Luck

After riding for awhile and I turn off the bike I get drips of oil coming out of the air cleaner .

It depends on the year model of your bike. This thread says your bike is a 01 FXDXT Super Glide. Since 1994, all Harley engines have been what we call "head breathers". The crankcase ventilation is done through ports in the heads unlike previous years where the engine breathed thorough a port in the lower crankcase. In each version, there are baffles to seperate the oil mist from the air. The later version "Head breathers" were better at this than the earlier versions. Still some oil is blown into the air cleaner and makes the removal and cleaning of the inside of the air filter necessary.

However if there is too much oil building up too quickly, in the head breather models there are small "umbrella" valves in the center part of the rocker box covers that over time become brittle due to head. It's not very difficult to take the top off the rocker box cover and replace these umbrellas if you have the proper tools and know how.

On the twin cam engines, there are six bolts holding the top plate on the rocker box cover. Remove these six bolts and the top plate and the center plate come off the head. The umbrella valve is in the center part. Simply remove the old umbrella and pull in the new on in the proper direction. Replace the rocker box covers with new gaskets.

Stovetop lamp sockets very brittle and are disintegrating.

In effect (given the unit is wired correctly) without insulation on the socket, you have an exposed neutral wire in your oven -- this is certainly not as dangerous as an exposed hot wire, but does present risks. I recommend replacing the light sockets -- you'll sleep and cook a lot better.

Missing problem

Check the wire pigtail that plugs into the coil pack. The plastic insulation around the four wires become hard and brittle, this can cause shorting and cross fires. Carefully pull the protective cover back to expose the four wires that go into the plug, check visually then bent the wires to see if they are flexible. If they are flexible and not brittle it is something else. Check out this link for detailed information and tests.
