Reinstalling oil pump and cams on a 2003 Harley Davidson FLSTC

You may have the oil level too high and if you did not get the oil pump properly synched when the cam cover went back on or if you did not replace the o-rings you may have sumping going on now.

Camshaft timing procedure for 1982 harley davidson xlh 1000 cc
On the pinion gear there is a timing mark.
This mark will line up with the rear cylinder intake cam.
There are 3 marks on this cam.
One will line up with the mark on the pinion gear.
One other mark will line up with rear exhaust cam and the front mark on the rear intake cam will line up with a mark on the front cylinder intake cam.
The front intake cam also has a mark on it that will line up with the front exhaust cam.

When re-installing the oil pump, make sure it is aligned properly. If it's not, binding could cause your problem.

Go tell your mechanic that he doesn't know what he's talking about. I own a 1994 FXDWG and the only thing it does is seep a bit of oil on the rear cylinder base gasket. Your '94 model Evo engine is what we call a "head breather" in that the crankcase pressure is vented into the air filter through hollow "union bolts" that go into each head. If you or someone else has changed these bolts to eliminate the "breathing" effect, crankcase pressure can build in the engine causing it to blow the gaskets. Another thing that could be wrong is that your breather gear in the crankcase may have a broken tooth on it. This is the rotating "valve" that allows your crankcase to evacuate the oil into the cam chest so that the oil pump can pump it back to the oil tank. The gear is made of plastic and the teeth on the gear will break off. When this happens, the "valve" will either stop turning or become out of time with the crankshaft causing excessive pressure in the engine. Also, when installing the new seals, the middle and upper rocker box covers must be aligned properly to ensure the seal is not squeezed out or pinched.

Good Luck

On the shaft housing of the pump that goes up into the gear case, there is a "window" or little cut out place. With the cams installed and timed, slide the pump into the gear case with the mark on the pump drive shaft aligned in the window. It has been a long time but I'm pretty sure I'm right on this.

Good Luck

First, make sure you've got the oil pump drive gear and the pinion on the pinion shaft of the crank and the nut properly torqued. Identify the cams. You should have a "1W", "2W", "3W" and a "4W". "1W" is the rear exhaust and "2W" is the rear intake. "3W" is front intake and "4W" is front exhaust. They go into the engine cases in order 1W in rear, next 2W over the pinion gear, 3W in front of the pinion gear, and 4W all the way to the front of the engine.

Install the "1W" cam. Then install the "3W" and the "4W" cam with the timing marks aligned. Now position the pinion gear with the timing mark straight up and lock the crank. Now, you must install the "2W" cam last making sure that the three timing marks are aligned with the pinion gear, the "1W" cam, and the "3W" cam.

If you can't figure it out, contact me directly at [email protected] and I'll send you a picture.

Good Luck

Order a V-Twin catalog, they're free.

If you have chain Tensioners then you have a Twin cam. This is NOT a job for an amature. Its necessary to take out Push rods which means remove heads or cut your pushrods and reinstall adjustables. You need to take out your cam plate,re align oil pump..Its not a simple job for a novice. If you have noise they have already exploded or are about to. Do not ride your bike..those plastic pieces can get sucked into the oil pump and do major damage. I told that to a customer that was going on a trip he did not heed warning. He got 75 miles they exploded and he bought a new motor.
