This seems like a dumb question, but... Is it possible to install the cams 360 degrees out? I've got all the dots line up on my new cams, (Andrews N8's, '99M2) and the third dot on #2 cam lines up with the line on the crank gear.(just like the pic in the MM) #2 piston is near TDC and #1 (front) piston is close. I am assuming for all intent and purpose that the slash mark on the crank gear will put the crank and pistons in exactly the same position regardless of whether it's rotation #1 (360 degrees) or rotation 2(720 degrees) as the crank rotates 720 degrees for each complete combustion cycle to the cams' one (360 degrees.) So it shouldn't make a difference, right????????????? The MM says nothing about rotating the motor 'til #1 is on the compression stroke, or any of that stuff. It just says to line up the marks (dots), which they are. | ||

Capt, I thought the same thing when I did my cams, but when I got her back together, she fired right up, I just had to tweak the ignition advance some. | ||

Thanks, Blu. After thinking about it a little more, I decided the crank and pistons don't really care whether they're on round one or two. I guess I was trying to outthink myself.(unless, of course, I'm wrong....) | ||

Be glad you aren't just dealing with the issues that I am. I now have a tapping sound in my top end that is much louder than normal. Not a good thing. | ||

May be a collapsed lifter, plugged up pushrod, or other valvetrain problems. Pull the rocker cover and check for valve lash- there should be none. | ||

Did all that, found that I am not getting any oil to the top end. Pulled the filter and cranked it a few times to see how much oil if actually flowing through the system. Not a whole lot, and I mean just a trickle of oil is being pushed by the pump. So I pulled the pump and al the gears look good, and I spun the pump by hand with the outlet of the pump off so I could see how much oil was being pushed by the pump, again, not a whole lot of pressure or volume there, so my search begins for a high volume oil pump. | ||

If you feel the need for a better pump, Zippers makes arguably the best there is. H-D oiling systems are neither high pressure or volume systems...they don't need to be. Most aftermarket pumps offer a little more volume but improve upon the scavenge side significantly. Make sure you prime your oil pump before installation. | ||

I'm looking into the problem. Will keep everyone posted on the results.. |
