? about oil lines and gauge on a twin cam

Hey guys, Sorry to keep bringing this up, I just can't find any info on it at all. Every TC that I have looked at has the oil pressure sending unit up front, I just can't figure this shit out.

So its a 96" twin cam built in 2007, S&S cases, Andrew cams and everything else is HD. There is not port for a sending unit up front. My thought it that its been like this from day one and the bike hasn't been riden very much because it still has the original back tire.

I'm getting no oil pressure at all but I know its flowing good and I know the flow speeds up when I twist the throttle.

Can you guys take a look at your TC engines and see if any has the oil sending unit in the back.

Sorry , but I just woke up from my nap..Are you sure your oil gauge is good? All of mine have burned up mounted around that location..How do you know your flow is good if you have no pressure reading on the gauge? I know on an Evo...the oil pressure outlet is around the pump..

52, I know the old and new gauges work, 100% on that. As far as flow, I removed the return line coming off of the oil cooler and stuck the line in the oil tank fill port. It flows good and increases when you twist the throttle.
The engine isnt new and this pressure thing came with it when I bought it. My mods have only made it better and have nothing to do with the oil pressure.
I think the builder didn't install a check valve or missed something else. The enigine runs good and doesn't make any unwanted noise.
I have yet to hear from a person that has seen this setup, all the TC engines I have seen have the pressure gauge/sending unit on the front of the engine.
From the little bit that I have read about this leads me to be worried about a higher pressure over lower, specially on a cold startup.

Ok, I'm waking up now, but I don't see how you can have oil flowing through the system and not have any pressure showing on the gauge..?

Well, apparently the TC is a lot different than the evo...

I always thought that an oil pressure gauge outlet was simply a hole drilled (threaded) into the oil circuit.
If there is pressure on the system, in your case there is, ...since oil is flowing...then you will have to have pressure showing on the gauge, unless the small hole in the gauge stem is stopped up..I would remove the gauge and test it just to eliminate any doubt ..try hooking an air hose to it and see if you can make it register..or just see if oil squirts out the outlet hole when you turn it over..

like I said above, the old and new gauges work fine. Its not a gauge issue. 110% sure. My first thought was to put a little air pressure to it.

Heres a little ditty I found a few days ago. It kind of has me thinking the check valve for this system isn't in or done wrong. These S&S cases are different than HD and remember this engine is 11 years old.
Look at the pic in the OP, the oil pump configurations it a lot different than any other TC engines. it looks like an evo, don't let that fool you, its nothing like the it.


Twin Cam Oiling System Basics - Tech
Oil Pressure
To maintain proper oil pressure, the Twin Cam engine uses a spring-loaded pressure relief valve, which is located in the cam support plate. The purpose of the relief valve is to protect the engine from excessive oil pressure. However, a sticking valve will cause low oil pressure. For example, when starting a cold engine in 20-degree weather and using 20/50 oil, the relief valve will open and protect the engine from extreme pressures that can damage engine seals. In contrast, if the valve stops working properly and sticks open due to debris from worn chain tensioners or poor machining tolerances, oil pressure can drop below minimum requirements. Unfortunately, low oil pressure causes a domino effect. First, the hydraulic lifters start clattering due to a lack of oil. Additionally, the oil supply to the top end is reduced, further amplifying engine noise and clatter. To compound the problems, the piston cooling jets, when opened, usurp oil from the lifters.

The pressure relief valve consists of a plunger and spring. The plunger must move freely and seat properly to maintain proper oil pressure. In addition to being held open due to debris circulating in the oil, the plunger has been known to catch and hang up on a machining burr in the bypass port, thereby reducing oil pressure. Whenever you rebuild a Twin Cam engine or install new cams, it's important to make sure the pressure relief plunger moves freely and seats properly in the cam plate bypass port. Feuling makes a high-quality pressure relief spring for the Twin Cam with the correct spring rate to control and maintain proper oil pressure.

Gerotor Oil Pump
Twin Cam 88 and 88B engines use a small, die-cast, gerotor-style oil pump turning at crankshaft rpm that utilizes a spring washer to preload the pump gears against the cam support plate and pump housing. Over the years, the Factory made several improvements to the Twin Cam's gerotor oil pump, with the late-model 2007-and-newer (2006-and-newer Dyna) pumps being the best of the lot. Nevertheless, what you want in an oil pump is a pump that can supply the pressure and volume of oil required at both low- and high-rpm conditions in addition to sufficient scavenging capability to eliminate wet-sumping (sometimes called oil carryover).

Good research, I guess it's just getting more complicated like every thing else on the market..

Amen brother. You know we used to read here that a pressure gauge and or a temp gauge should be thrown out, they will only drive ya crazy.
Before I retired I used to get caught up in LA traffic, yes, even at 1:30pm. When my evo was done with it and got hot it would tell me, I'm just not sure about this one..
Ive got about 7K into the whole bike, it needs a new back tire and some nice leather on the seat, probably a new primary belt....
These are the things that I like. I'm no expert mechanic but I do like to tinker ..
I can always count on help from this site got to love it

The Thing that I don't like about the twin cam, even though It packs more horses for the same displacement, is that.... Walt Disney..... cam drive system, driven buy two small chains and with the fiber drag type tentioners. You have to check those every 20k miles or sooner for fiber particles and wear..like checking the brakes on your car..People have had them crack and break off also....I can handle the primary tentioner but don't like for the cams..that's why I sold mine.....It was a screamer though.

Doesn’t s&s have a kit, fully geared replacement eliminating chains altogether?

Not sure, but you would probably have to mortgage your house to do all that..all that junk in there is probably why they had to go with a higher pressure oil pump and this relief valve bunk..

I've had the bike all apart for various reasons. I thought
What the heck, took the gauge off and started the bike.

It sucks ......air with the gauge off.
