Oil Pump???

[lost_harley]

So I have this 2000 roadking which I had to rebuild because when the previous owner made it a 95CI, his "expert" put the old 88 oil pump in which failed and blew the cam bearing out of my case throwing metal through the entire engine. When a mechanic and I rebuilt it to a 95, I put the Screamin eagle Hydraulic cam tension-er with oil pump upgrade in with 510 cams. So my question is this...... when I have been riding a while regardless if it's a hot day or not, when I start it, it takes a while for the oil to reach the heads. Not long, but when it's "tapping" it seems like a long time. Maybe 15 seconds. I can watch it as well as I put in an oil pressure gauge. I think it's only the front jug though, which it strange because usually it's the back one that takes a hit?? Does anyone have an ideas or similar experiences?? If so what steps can I take to fix this?? It was suggested that I run straight 50W in it. Previously, I was running syn. and it was doing it then as well.

I wouldn't run HOT climate. What was the oil pressure on start up on the gauge? When I did my 2000 to a 95 I had a similar problem. I just put a new pump in it. Although, the new lifters I put in all but eliminated it on start up.

More than likely the cam bearings went out and took out the oil pump..     Check your lifters..  or pushrods..

When a mechanic and I rebuilt it to a 95,

How far down dd you take it?
Did you remove and clean the pan?
Were the lifters and PRs replaced?

IF the 2000 was with a BUILD Date of 1999 on the label on the down fork,,, the Ball style Bearing on the rear cam (drive cam) wasn't changed out BINGO... More than likely the rear cam bearing bearing let go first. IF later half of the 00 model year, INA's.

The Rear Ball Bearing in the cam-plate needed to be changed out to a Roller style bearing.... HD did NOT recall it as it needed to Blow Up before they would do anything about it..

I changed my own at 14,000 miles on my Early 2000 model Dyna... My finding; 

It Was cracked on the Tin bearing cover spacer and close to balls letting Loose all to one side and Bang.

Just a thought IF not on your 2000,  it may stir another 99/00 owner to check his Build date...

Like Bubbie said all 99s and some 00s had this potentially defective rear ball bearing.  Everybody I personally knew who had one had a failure, yours truly included.  One guy had 2 failures before the roller fix became available.  Harley offered a special 5 year warranty on just that rear bearing.  Lots of folks were buying Harleys back then and finding out they really weren't motorcyclists, so there are potentially many of these early models out there with low mileage and rear outer ball bearings waiting to grenade.  There was never any documented problem with the early oil pumps.

If ya got a 99 you owe it to yourself to fix this issue before is causes you lots of grief.  The MOCO will not help you now.

Awesome replies guys. That's why I hang on this forum. I think I'm heading don the right path. With the rebuild, I put in the roller style bearings and changed the pushrods (as I said, the "professional" put in old crap, and the pushrods weren't adjustable?) so lifters it is. And yes, I did get the hydraulic kit with a new oil pump

cheers

X2!

Nothing really wrong with the original oil pump at least not till it eats the junk when the bearings and tensioners let go.

I have an early 2000 Heritage built in August 99. After seeing friends go through the horror of bearing and tensioner failure, I pulled mine apart and put S&S gear drive and cam kit into it using the original oil pump doing a 95 kit on it while it was apart. The gear drive makes noise but keeps on trucking. Here we are 13 years and a lot of miles later.
