Absolutely!!! Have you replaced the stock cams with gear driven cams? On almost all cams there are "dots" or "circles" to mark where the cams should be. Additionally if using gear driven cams depending on who makes them there may some additional installation considerations, grinding for clearance, etc.
Also refer to the cam documention on piston position when installing. Hope this helps.

2003 Harley Davidson FLHT Electra Glide Standard no oil pressure

Hi, Paul "OUCH" I feel your pain I too own a 2003 FLHTCUI Anniversary Edition I only have 25,000 miles on it but upgraded a long time ago to the S&S 510 gear drive kit eliminating the cam chain and shoes, it's a bit pricey $600. That design was not one of Harley's greatest hits and they refuse to change it. They did, however, reduce the inevitable shoe failure by eliminating the left spring actuated shoe and replacing the right one with a hydraulic version, but it's still a shoe with its own set of new issues like premature chain stretching according to fellow Harley Techs that I chew the fat with. My gut tells me that:
1. You still have oil pump issues.
2. Somewhere in the cam plate or oil passage in the engine case is a left over piece of shoe that is in between the pump, the connecting rods or lifters blocking adequate flow to the top end.
3. On the bright side, that same piece of the shoe could be in the passage way that goes to the oil pressure sending unit or gauge.
If it were me I would go back into the pump and double check the integrity of all seals and o-rings check the lobe clearance of the pump gears .004" max, check the bright side #3 and every night before you turn in drop to your knees and thank the Harley Gods for keeping your engine in one piece.

Oil coming from air cleaner how to stop this problem

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.

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

My 1994 FLSTC keeps blowing out the front top rocker arm box seal every few thousand miles. Mechanic said it is due to poor design that year on how seal sits? Any suggestions?

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

Set oil pump breather timing 1976 sportser

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

Tming settings on gears how to put them together by the marks

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 and I'll send you a picture.

Good Luck

Harley davidson how to change tensioners

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.
