Drained twin cam oil


Sorry don't understand this one the Daelim is a 4 stroke engine. The oil pump forces the oil around all parts including the head where the cams are. If you drain the engine oil from the sump plug you refill as per the user manual. Never heard of just draining the cam assembly.

Changed oil pump still low oil pressure 2004 twin cam


First off, if you are going by the idiot light, it COULD be a bad sending unit.
Either replace with a new one and check again, or hook up an oil pressure gauge (At 2000 RPM you should have 30-38lbs) to get a more accurate reading:

http://www.harborfreight.com/160-psi-dry-gauge-68249.html



IF is is still ACTUALLY low, pull the relief valve spring and make sure its clean and nothing it blocking it from seating correctly.

A cracked cam plate could also cause a loss of oil pressure.

Finally, make sure that the oil line fron the oil tank to the pump (feed line) isn't plugged.

Broken oil pump need to change


Why, why, why do people expect a decent answer if they do not give complete information, in this case MODEL YEAR?

In 1999, there was a change over from the Evolution engine to the Twin Cam engine.
This resulted in a total change of the oil pump.
Up through the Evo, the oil pump was mounted to the outside back end of the motor case, and could be remove - reinstalled/replaced fairly easy.
Starting with the Twin Cam, the oil pump was completely redesigned and move to inside the engine, so you have to go inside to change,

Either way, beings as the oil pump could be considered the "Heart" of the Harley's circulation system, you should know what you're doing if you plan on tackling this yourself.

In my first attempt to change my engine oil, I drained oil from bottom of my 2001 Fatboy, from the plug on the right side towards the front of the engine, just below the Twin Cam Cover and floor board,...


I'm not that familiar with the Twin Cam engine but from what you're saying, Harley has a drain or something in the cam chest of the Twin Cam engine. This is something new for Harley as the previous engines had no means of draining the cam chest. I would imagine that this is what the oil you saw was, oil in the cam chest waiting to be pumped back to the oil tank by the oil pump that is located in the cam chest. When you restart the engine, this area will again fill itself to the proper level.

Good Luck

"Oh, and now I can\'t even read the oil level on my dipstick due to the fact it is significantly LOW" This is not a good sign. Now, my expertise is NOT on the Twin Cam bikes but I do try to help when I can. In your case, if your engine were an earleir Evolution or Shovelhead engine, I'd say that you had sheared a scavenge gear drive key in the oil pump. Now, I do not know a thing about the oil pump in a Twin Cam as I've never worked on one. It sounds like your oil pump is not scavenging (sucking) the oil out of the engine and pumping it back to the oil tank. Once the pump pumps the oil into the engine, it stays there. Thats why you're seen the "massive amounts of oil spitting out of the little hoses behind the air cleaner". Take your bike to a dealer or qualified shop as soon as possible and I'd refrain from running it. An engine full of oil would also expain why the engine does not want to run as well.

I'm sorry but I don't have an oilling diagram of a Twin Cam. The way I check for blocked passages to the tappets is while I've got the tappet blocks out, I turn the engine over using the transmission in high gear and turn the rear wheel with the plugs out of the engine. I watch for the oil to pump up and out of the engine. Now, since I don't work on the Twin Cam engines I'm going to say something here that I'm not sure about. See if the engine has a tappet oil screen like an Evolution engine does. It a plug with a very fine mesh screen thingy that all the tappet oil flows through. Keeps trash out of the tappets.

Have you ridden the bike since you replaced the tappets? Sometimes you have to ride them a ways to get all the air out of the tappets. I've had to ride them for ten miles to get them to quieten down before. Now, if you only have one tappet causing a problem, shut the engine down and pop the pushrod tubes immediately. Try to turn the pushrods with your fingers. If can turn one or two, there is your problem

Good luck

On my 2003 fat boy all oil from tank is in engine and won't return whats the cause ? runs real rough


Ok, I'm not exactly sure what the problem is on your Twin Cam but I can assure you that it is oil pump related. One the earlier models with the external pump, you had two pumps in one body. One pump was a "feed" pump that pumped oil into the engine. The other pump was a "scavenger" pump that pumped oil out of the engine back to the tank.

When Harley designed the Twin Cam engine, they employed a better design of pump inside the engine. It's located in the gear case along with the cams. I do not know too much about the Twin Cam engine as I specialize on the older Evolution, Shovelhead, and Panhead engnes. The older engines had a breather gear that used the crankcase pressure built up inside the engne to blow the oil from the crankcase into the gear case. I don't know if the Twin Cam still uses that method of getting the oil out of the crankcase and into the gear case.

So, with my limited knowledge of the oil pump on the Twin Cam, I'd say that this is the problem. You need to find someone that is familiar with the construction of the pump. It may be that the entire pump is bad or something as simple as a sheared pin.

Good Luck
Steve
