No Oil Pressure Twin Cam Dyna.

No Oil Pressure Twin Cam Dyna.

Cards on the table, help yourself!

Hello All.

The Bike is a 02 Dyna Wide Glide.

Let's start from the beginning. I sent out my heads to cycle Rama, and had em send me their 100hp/100tq set up (Pistons {95 inch},
cams, lifters). In Addison, I added the new
SE oil pump and camp plate (the black one). S&S gear drive for the cams and Daytona Tec ignition. 44 CV carb. Everything was working
great, but I thought that the lifters
Where a little too chatty.

First time I put it together, I messed up the front cylinder valve adjustment and on start up, it was ticking like mad, and I heard
a 'pop' before shut down. I reajusted the
Push rods and everything was running ok.... But I figured that one of the lifters was damaged, so I planned on replacing the
lifters.

But first, I was turned on to a cheap pair of roller rocker arms ( http :// www .fastengineparts,com /products_view.php?id=2222 ). You
get what you pay for... The roller tips are held in place
with tiny c-clips on the ends of the roller shafts. I clearance the rocker covers for the extra height of the rocker arms, and
installed them in. Everything was working Ok. Cold weather
set in, so it was on the back burner until about two weeks ago. Tearing it down to replace the lifters, I noticed the front cylinder
roller rocker arm shed its little c-clips, and they are no where
To be found. I pulled the cam cover to see if they where in there, but no dice. I figured that they were in the bottom of the oil
pan, or in the bottom of the engine case, or chewed up
by now (I had driven about 150 miles with the roller rocker arms). I tossed em, and stuck the originals back in. I put in the new
lifters, made the adjustments, and started it up.

No oil pressure. 0

I didn't plug in a oil pressure tester.. didn't have to... Clacking like a model T.

Well, must be the c-clips (2) clogging up something I figure. So I tear it down. Pulled the cam plate and oil pump, and everything
is super clean (SE oil pump doesn't have a rubber
o-ring around the gator gears like the old one did, jfyi). All the oil passages are clear, but still no sign of the little clips.I
put everything back in, changed the oil filter, and the oil. I
put about a quart in the top of the push rod tubes to fill the cam chest a little to help prime the pump. No Dice.. Still no
pressure. I pulled the cam plate again, and checked the
spring plunger... everything looks great... no damage at all, and all passages are clear. I'm stumped here... I had oil pressure
just fine before. The pump just isn't getting the gold
stuff from the oil tank.

What can you make of all this mess? any ideas would be greatly appreciated.

Re: No Oil Pressure Twin Cam Dyna.

This is a piss poor explanation but it's the best I got right now. Hopefully
someone has a better one. I don't own a twin cam but my buddy does. we put
in a gear drive and on reassembly put one of the washers, that is part of
the gear drive oil pump, in on the wrong side of the oil pump. It looks
right and goes back together just fine, but has NO oil pressure. A quick
disassembly and we saw our error. Easy fix. I hope that's your problem.
