Don`t spend your money on an oil pump, you will be right back here after you install it and wonder why the oil pressure is still low...
There`s a reason your bike didn`t come with an oil pressure gauge...it doesn`t need one.
The oil pressure on a hot Evo or Shovelhead will often not even register on a gauge, unless it is a quality, calibrated gauge, and a few pounds is all you will see.
Don`t expect an oil pressure gauge to make you happy, it will only make you nervous.
If the pressure is too low, the oil pressure light will come on and the valve train will clatter, loudly.
If you feel something when you put your hand on the pushrod tube, you may have a pushrod rubbing the tube.
Make sure the oil pressure warning light is working properly, and make sure the oil is being returned to the tank.
If you must check with a gauge, use a quality gauge that will be accurate under 10 PSI.
Ok, That makes sense. It does have a gauge, oil psi wont read when hot unless I give it some gas, The oil must be returning to the tank, It has a oil temp gauge that reads directly from the oil and it will read 150 - 180 at normal operating,, You think it could be a push rod rubbing ?? And why now.. Does not run the same eather ,, Thanks for your input ...
Sorry, I thought it was a valid question ... Maybe I should have asked about the weather...
Well, putting in an oil pump is not a ten minute operation and will entail taking the right side of your engine apart, and cams out. And, if you don't cut and replace the pushrods and tubes, the tank and rocker boxes and rocker arms must come off too. If you are comfortable with that , changing the pump is a piece of cake. If that is a challenge for you, take it to a mechanic. It is not as simple as changing an oil filter and making a mistake can get real expensive. Food for thought!
