The bike is a 2002 FLHTCUI, 88ci, injected. Oil pressure had been consistent at 32 until a couple months ago when it jumped up to about 40 at 2500 rpm. I checked the oil level and thought it was reading about a quart low so I added it. Ran it about 100 miles, then this morning I started it up and it dropped to nearly "0". Would only come up to 10 at 3500 rpm. Did overfilling the oil cause the problem? Does anyone have any idea why it the pressure went up and fell of the table? I am not a wrench-turner and need some advice.

Thanks

 

How many miles on the bike? Cam chain tensoiner shoes could have sent a piece through the oil pump. I would not run it until the cam chest is opened up and oil pump, cam plate and shoes are checked. At this point you may have gotten lucky. I may be off with my assessment but that is what I would be doing if it were my bike. Good luck and keep us posted on your find.

 

Verify with a mechanical gauge.

 

Check pressure sending unit and gauge.

 

I would pull the cam chest cover and take a look. Most likely is a cam chain tensioner shoe broke off a piece and it scored the oil pump surface.

 

If possible check with a mechanical gauge. Depending on mileage you may need to inspect tensioners. Mine were shot at 32,000. My indication was fluctuating oil pressure readings.

With a 9 year old TC,i would check the tensioners and cam chest as said before.

 

Sorry to say it sounds like it could be the tensioners,if they haven't been replaced I would check them before running it again, you might still get lucky & not have to do a complete rebuild.

 

Do the easy stuff first...Check the pressure. Old sending unit, Old guage.

And as an owner of an old TC also, I assume you know to keep an eye on your tensioners too.!

 

I usually agree, but I had the same thing happen & tried replacing the sender with no luck, the tensioners were toast. The more he runs it the more chance he has of doing major damage to the engine, plus there's no reason to spend money on a sender or gauge, if anything check with a mech gauge, which usually means taking it in or buying one. If the OP checks back in with more info we can give a more educated guess, IE miles on bike & have tensioners ever been checked.
