FYI, I just had my compensator nut tightened under warranty on my 2003 EG. Apparently Harley have changed the procedure. It is now tightened to a specific torque (dont know what it is) and then turned another x degrees (I think it is 90 but check for yourself).

My dealer,H-D of North Texas,cranked it down with a air impact wrench before I had a chance to say anything.

I'd have thought they would have followed their,H-D,own procedure.
Nope the cheapest,fastest way they could do it under warranty.

My gaskets have been reused several times not a drop.If the nut is loose enough to move the chain an inch it may be hitting the back side of the outer cover.Good Luck

I'm just trying to understand the idea of why they call it the sliding cam. The ressemble was part for part, no deviation an no parts left over. Everything is tied up right as well.The outer cover P/N 40384-91 has four circular springs that installed and the cover is bent in four locations to keep them is. I looked to see the size of allowable pic and if I make them that small U will never be able to read them. Is there another way to send them. This site shows the assemble: http://www.riveraprimoinc.com/catalo...COMPONENTS.pdf
Many thanks

Because the outer cam actually slides, to give a 'buffer' if you will, so that it does not create such a great shock to the system when changing to another gear (up or down), and especially taking off from a dead stop.

You can see in that pdf file, where the two cams are pictured installed, the amount of space provided for the outer cam to 'slide' between engagement of the lobes. The lobes being a 'ramp', and the springs to provide more 'dampening' of the engagement as they are compressed. All of this works just to absorb the initial shock of engagement.

'Sliding Cam' to differentiate between the two. If you said just Cam, it would be hard to tell which cam you're speaking of, since the compensating sprocket also has a cam on it.

After reading over what I just typed, the outer cam actually slides in and out, along the shaft. Perhaps that is the true purpose of the name? Sure sounds more likely to me, now.

Thanks for your repy: Your right, I did not specify which cam and I'n sorry for that. The assemble I was speaking of is the front compensating sprocket cam.

Just to satisfy my mind, I took it all apart again and mic'd everything added it all up, and then to further satisfy my mind, I went to the local HD dealer here where I've had the bike one time and put the question to them. It turns out that YES, when all componets are tied up the so called sliding cam gets torqued up to the point where you cannot make it move them independantly by hand. The inner springs I refer to are what is called V type springs. These look kind of like spacers of sort in the sprocket cover. There are two sets in the cover. This is what the four dimples are for on the sprocket cover. They are to hold the springs in so they don't fall out. These rings compress when you tighten the 1 1/2" nut to 150-165 ft lbs with 271 loctite.

Thanks for the effort on your part to help answer my question though.I really appreciate it.

Primary chain question

Sorry, this is my first post, in the event it doesn't go to the correct place... I have a 2003 FLHRCI with 44K miles on it. Stock engine with hydraulic cam chain tensioners, SE cam plate and upgraded oil pump. Stage 1 kit with Samson pipes. I was told to replace my primary chains at 40K by a dealer tech. Any truth to that? Also, I will be upgrading to an automatic primary chain tensioner. How much should this cost?

I was just glancing thru this thread and came down to your post....first Ive heard about replacing chain @40k? I would start a thread with that question before taking the leap......if your replacing the tensioner everybody is going to the Hayden M6 tensioner with good results...stay away from the automatic OEM adjuster as its reported to over wratchet causing IPB damage.

Primary chain stretching is dependent on how hard you ride your bike. I have 42,000 on my 05 RK custom and it's still within specs. More worry is the valve cams shaft wear shoes. They are a must about 30,000. I replaced mine with gear to gear cams. Darn near lost my oil pump if I hadn't caught it.
