    Shortly after I bought my 1st Harley, a 2002 Road King w/35,000 mi. I learned about the nylon shoes breaking. I pulled it apart and found it had better cams put in and also a chunk had broke off the inner shoe so I caught it in time. I put a Screaming Eagle Cam Plate in and new case bearings. Glad you covered just the pump and always wondered why is there no screen as most engines have to prevent any chunks entering the pump? Seems there is room to have a screen on intake to prevent blowing an engine from a siezed pump. Excellent video, Thanks.

    Yes I did get lucky. My first Harley and learned about those cam chain shoes on Y.T..... Before teardown I asked meticlous previous owner and he knew nothing about it. He said it runs great, not making any noise so he wouldn't worry about it. One chunk from the inside shoe, with no missing fragments. Still, why is there no inlet screen? Is there aftermarket screens? Beautiful bike but now it needs swing arm bushings as wheel is about 3/4 " to the belt side. Didn't notice when I bought it. Maybe you can do a video changing your bushings.

    The reason there's no screen on the scavenger side of the oil pump is the internal pump design has a problem with scavenger side of the pump. A screen would only make it worse. What Harley has done to compensate for no screen on the left inner case there is a deep well that collects any foreign debris. It works well, but when you get to much debris some will run thru the pump. That's when it tears up the motor. The engine itself does have a small cone screen between the pump and the case, but it's very small and if it gets clogged will starve the engine of oil, this cause damage to the engine. Personally I don't like the internal pump. I like the old style external pump which worked extremely well from 1937 till 1999. If I get a swing arm that needs bushings I will definitely video it. Thanks for the input and thanks for watching.

    @@tinkeringwithharleys it wasn’t in the pump just when I took the cover off and you see the plate. It was metal flakes and some larger chunks at the bottom of the inner case. Not too strong with the terminology haha. But where all the oil collects at the bottom is where they were. I’m hoping it was just the busted gear teeth or something. But it made it 110k miles so I’m guessing it just gave up eventually. Harley doesn’t even make the oil pumps anymore, they ruled them “obsolete” apparently haha. Thanks for the reply man! Hopefully getting a new high flow oil pump with a cam plate soon.

So make sure to take it all apart to make sure it’s just the pump. The new engine I got, another tc88 was from an 02 dyna, threw that in and got about a thousand miles out of it until the pump in that one took a crap. Thankfully didn’t send metal anywhere, stayed together just broke the gears inside itself. My pressure relief valve was also stuck on the cam plate as well. Went ahead and got the whole cam plate, pump and hydraulic tensioner upgrade. Didn’t wanna deal with it anymore haha. The engine supposedly only had around 9k miles on it, got about 11 or so now. Everything seems to be running good! Best of luck to ya man! If your pumps out I’d just go ahead and save and get that whole upgrade for it if it doesn’t have it already.

    It's possibly the sending switch. You'll find that down by the master cylinder for the rear brake. Get yourself a paper clip and open it up, unplug the sending switch. Stick the paper clip into the wired plug the 2 contacts in the plug. That completes the circuit. Start the bike if the light goes out it's a bad sending switch. If you're concerned about the oil pressure remove the sending switch and get yourself a oil pressure gauge and screw it into where the switch was and start the bike, that will give you a accurate reading on the oil pressure. Also on those earlier years when the bike is throwing a code the oil light will come on. To check the code hold in the mileage button on the speedo head. That will give you the code. You can than look up on the Internet what the code is for. Hope this helps. Thanks for watching.

    Thanks for the question, I'm guessing you have a twin cam and not a Evo since they made both in 99. Top ends on both have tendency to be noisy. I have a 2000 tc, rebuilt it also added the high volume pump. After about 25,000 miles the top started to get noisy again. The high flow pump may quiet it a little but you'll still have some noise. Hope that answers you're question. Thanks for watching and ride safe.

    Hey Tinker how are you? I have an 06 Softail and also changed out the mechanical tensioners with hydraulic, and the kit did come with the new high flow oil pump, my question is how much PSI difference is between the old style,99-06 pump, and the new high flow pump that I installed from Screaming Eagle, what would be the norm on your oil pressure gauge, it's a stock twin cam 88b motor Thanks from Fl.

  • @tinkeringwithharleys

    Hi Scott, from the screaming eagle kits I've installed idle psi is about 15 psi, under power is usually around 30 to 35 psi. So the biggest change you see is at a idle. PSI increases from 9 to 10 PSI to 15 PSI. Under power doesn't change much from stock. The biggest difference is you have a lot more oil volume in your engine which helps cool it down. When you start it cold you may see the oil pressure jump up to 45 to 50 PSI but as it warms up the pressure drops to the pressures that I stated above. Hope that answers your question. Be safe and stay cool in Florida

The pump I show in this video is strictly for Twin Can engines. Harley made both the Evo and Twin Cam engines in 1999. Hope you are well.

    Thanks for the question Steve, nope it's not necessary to collapse the push rod or lifters. If you have adjustable push rods you may need to adjust them after you install the lockers and reassemble everything. If you have stock push rods you don't have to do anything. Also after you torque the rocker platform down give it about 20 minutes to let your lifters bleed down before firing the bike up. The lifters will refill with oil when you fire up.👍

I have to use a manual hand pump to draw oil thru the sending unit port then the oil pump puts out 25 lbs pressure. It has 12,400 miles on it. It’s been in a garage all this time before I bought it.

    Thanks for the question, without seeing the bike it's a it's tough to diagnose but I can try and steer you in the direction to look. It could be a number of things. It sounds like the oil pump loses its prime after sitting and once it is primed it's should have 32 to 35 psi oil pressure cold. The Dyna in 06 was the first year of hydraulic chain tensioners. Where I would start would be the oil pump. It sounds like it's just worn out even with the low mileage, check the scavenger gear for wear or possible obstruction. Also check the cam plate. Check the pressure relief valve to make sure it's not stuck open. Inspect the cam plate for small cracks. It could be anyone of the above or a combination of the 3. I hope this helps you.

    Great, it's normal at a idle for the oil pressure to drop to about 8 or 9 psi. Once your under power the oil pressure should go up to 30 psi. This is how the stock Harley pumps work. They rely on flow not volume. As long as your not hearing a noisy engine at a idle your pump is working exactly the way it was designed to. Thanks for the question and thanks for watching.

    If you have the spring loaded tensioners and they've failed you would hear it and the bike would run bad if it ran at all. Failed tensioners when the pieces run through the motor it destroys the motor. If you're dumping oil through the breathers I would check the breathers heads. Also if you've had some recent motor work done and a passage has accidentally been blocked that would cause the high pressure.

    Thanks for the question. Sorry to hear about your health problems, hoping you've recovered. This is a first I've ever heard of a oil pump being corroded. The twin cam 88 has a internal oil pump which is in a sealed engine. The only thing I can think of that would cause this is if moisture got into to the engine. If that's the case you'll need more than a oil pump. The stock oil pumps usually last about 50 to 60,000 miles. So the short answer is no this is not common. Like I said I've never heard of it before. Thanks for watching
