I have a 2007 ultra classic, I took it for a ride last week and was having trouble with the oil pressure , came home, parked it and then it wouldnt restart. I took it in and they are saying that my motor is fired,because the pins are sheared and the pressure release springs are shot, causeing the motor freeze. Is there any recall on this or how could this have happen. im not a red liner
it is me again with the 2007 ultra classic. what could happen in 5 minutes to destroy the engenie, because of oil pressure, oil was full and clean ,bike still ran, but i dont understand how this ruined the 2 fly wheels and ruined the cam ,when st croix harley hasnt even tour down the enegine, when all they have done is pulled the oil pump, this makes no senseit is me again with the 2007 ultra classic.

Re: I have a 2007 ultra classic, I took it for a ride...
I am not sure of these pins or your pressure release springs you are talking about.The only pins that i know off is the piston pins or the pin in the cam plate that retains a spring and plunger.

change mechanics --or bring back and have them fix correctly when they did the engine work doesnt sound like was done correctly and now you may have a bigger problem
The engine is sensitive to oil weight and quality of oil due to the valves lifter being hydraulic lifters. Yes changing the oil could help. Lifter may have failed. Oil pump my have failed.
My first stupid question is do you have any oil? Is it full?
Second, a co-worker had a twin cam engine (as yours is) and the oil pick-up fell off. This meant the oil pump couldn't return the oil to the tank, and his lower end of the engine filled up with oil. On his, the oil pressure sending unit works on the return side (as the oil filter does), so it read no oil pressure, and no oil returning to the tank through the oil filter.
Most likely problem is a badly fitted seal/gasket this can cause the oilways to be blocked, take it back and get the technician to check it.This is an easy thing to do, because of the fine tolerances in the oil pump. A motor rebuild is a real pain and I'm sure the shop would rather not pay for a new motor.
Use an ohm meter to check your sending unit. Disconnect the wire from the front of the sending unit. Put your meter function switch in OHMS, R X 1 range. Put one lead to the stud where the wire came from and the other lead to the engine. You should read zero or very low resistance. Start the engine and you should read a very high resistance. If not, your sending unit, oil pressure switch, is bad. Other wise, you may have a problem with the wiring running from this switch to the gauge.
If your engine has no oil pressure, your tappets would be making a very loud rattling noise. Kinda like a tin can full of rocks. If your engine is running normal and quietly (mechanically) you have oil pressure.
Very common on h-d big twins for the last 75 years or so. These bikes have a dry sump oil system which means you have 2 oil pumps, feed and scavenge. The feed pump is very puny compaired to the scavenge, so at idle (especially when hot) it carries only a couple of pounds of pressure and that is all you need. The scavenge pump has a much greater capacity because if it can't keep up the crancase will start filling up and the crank will start slogging through the oil, killing performance. These bikes are equipped with hydraulic valve lifters which will start clanking loudly if you have a real oil pressure problem. Enjoy your ride and don't sweat it.
ok it is the pin on the cam plate
