Hi Guys, sorry I have been MIA with this thread for to long. I started a new job and have been wrapped up in all of the fun nonsense that comes with that.
Anyways, I got a pressure gauge and put it in. It shows high pressure on start up like 50-55 psi.
I took it for a rip and maybe 2-3 miles into the ride my oil light pops on. I look down and it shows that I have 40 psi still. But there is a whine in the motor when the light pops on and it seems to get louder. I brought it home so maybe 5-6 miles total and am going to begin to look into this situation more.
AMF was trying to chase the clicking noises that shovels had hot city driving - and in the adventure they did a pile of changes cone shovels one was they set the cam gear tight - actually tighter then it should have been this causes a whine - if you look in the factory book you will find 1/2 dozen pinion drive gears for the cam and another 1/2 dozen or more cam gears - that combo gives you all kinds of choices
the spec no one has the tooling but them so - its a slight drag with everything in place less the lifter blocks on the cam back and forth with no washer so it has movement to feel
Ok So the whine maybe "exaggerated" in my head because I am looking for something. The whine has always kind of been there it goes up and down smoothly with the rpms.
So at this point I am leaning towards disassembling my oil pump and and checking everything out inside.
Wrong time of year to go and look for troubles - we tell the guys to hold off till it snowing no rush and its something to do rather then sit and watch the goonee box with jackasses that make way to much money and have the ***** to tell you what they think
Ok so here we go going to continue to until it is good and dead.
So I went for a ride this evening. After checking my oil pressure switch and redoing the connection.
dummy light stayed on after starting the bike.
I ignored said light because the gauge I installed showed 50 PSI
dummy light shut off 300 yards down the road.
I then went for a nice cruise on a horrible New England road.
Sitting at a stop sign to turn onto a main road and head home the dummy light came back on.
Still have 45psi on gauge
I cruise home in 4th gear 50-65mph until my driveway
Light never shut off.
Front cylinder is a little warmer than the rear by like 50-70 degrees, Bike has been like that since I rebuilt it. I used my infrared temp gun.
I used the IR temp gun to temp the oil and it said 130*F seems legit?
I also took pictures of the Motor with a FLIR camera and well the damn battery died and I cant upload that until it charges but temp seemed even.
Should I pull my pump, at least the cover and get eyes on the inside?
Does this have something to do with the check valve or pressure plunger?
Still running straight 60wt
I am ordering a new Oil pressure switch which one will be my best choice or can I pick a good one up at one of the chain auto parts stores Napa, Pep Boys, Auto Zone etc...
Attached are two pictures both of the gauge and pump Bike is not running
You have an S&S evo pump on a shovel - it has way more pressure in and out of the engine and you have a gauge i guess you don’t believe and a china oil pressure switch that you are convinced is gospel
wow just wow - i do not know what to say
Harley oil pressure switches are low pressure switches — not car switches that are HI Pressure switches and you want to use one of those so the light might do the same thing — and in the middle you want to remove the out side cover of the oil pump only - Y - what will looking at two gears in the pump do for you

John you are getting cranky LMAO!
I will trust my gauge John. I will trust the Crappy **** Chinese gauge seeing how no one sells good **** anymore that doesn't cost a weeks pay. You are the first person to tell me that I have that type of oil pump.
So the China crap pressure switch might be wrong because i ordered it for a shovel back when i replaced it.
So possibly its been broken due to the increased pressures?
Replace it with an Evo switch?
Out of curiosity and for myself what makes you say that is an Evo pump? (my pressure readings? how it looks?) I only ask because we have spoke on this pump before in here on the forum and that has never been mentioned.
I would open it up to see if Maybe I sheared a rear key only and was not getting good oil return which would impede the oil flow in but not affect the pressure. Maybe there is a piece of **** stuck in there or something. I would pull it just to verify everything was ok.
John I love your knowledge and appreciate all of it and the time you take to educate someone like me from the younger generation so I can be the guy getting grumpy with the young pups one day about some old solid mount shovel
All S&S pumps are evo platform - the small screw caps the same size is the evo give away that influence the different pressure pump from a real shovel pump
is it bad no does it work yes and yours happens to like it most shovels do not - be happy yours works
oil pressure switch for an evo is much longer then the shovel and mounts in the block in the main oil pressure feed passage
shovels switch is in the pumps pressure vane is that good it works for that pump
buy another shovel switch and if it still come on take the bulb out and a Advil pm so you can sleep at night
sarcasm is always freely given in the time of need - your going great just dont think you will ever have the oil pressure you think it should have because it wont
