Thought I posted that part # before in my install thread, but here it is if I didn't: Part #25225-70C, I paid $3.99 at the local H-D dealer.

Cam swap! Did you say cam swap? My Dog has been down for months doing a major rebuild. I started just replacing the transmission again due to the nut backing off the shaft causing the input shaft to move and loose all shifts. Then I looked at the base gasket leak that has been getting worse and decided to change out the gasket. That turned into a fresh set of pistons with the shorter cylinders which meant a 600 cam would work nicely now. Then decided to install the cam with new lifters. While waiting on the transmission to come back from Baker I wanted the Baker Belt Drive. You guessed it, I ordered the belt drive. Got all the parts in and was waiting on the cylinders for about 2 months. Guess they were made in China or something. While waiting I looked at the heads and decided to freshen them up. Sent them off to have new guides installed and a valve job. Couldn't wait to install everything so I could make it to Thunder Beach. Stayed up late working on the Dog. Took a break once I got the heads on and went to sleep. Woke up and started to work on the Dog when I noticed the first 2 fins on the NEW front cylinder had a CRACK!! Now waiting for a new front cylinder. I think it will be cold before I get this bike back together.
Oh yea, you were talking about a cam swap huh? Sorry I got carried away.:loony:

Cam swap update:
The Postman and I took our K9's for about a 250 mile ride today with the new .585 cams.
The cam makes the engine have a little more of a "Po-ta-to" sound while at idle. Riding 2-up with my wife I got 45 miles per gallon on the first 100+ miles, and then got 41 miles per gallon on the second 100+ miles. There feels like a noticeable increase in low end torque which was exactly what I was looking for in the cam swap. I enjoy cruising down the road in the 55 to 65 mph zone, and I rarely wind the engine past 3500rpm before shifting. No increase in valve train noise, and overall I am very happy with the cam choice. We were riding the hills of Tn. in the Rock Island area, some areas are very steep and sharp curves. Performance is exactly what we hoped for.
Rode some if the snake on the NC side of TN. Sweetest day of riding in my life. Real knee dragger turns, excellent country in the US:flag:

Bowhunter, not to rain on your parade but, when I do a cam, I usually remove the tappet blocks to have access to the cam from the hole In block where the tappet blocks mount. Why? Because I check for cam end play by installing the cam, mounting nose cone and new gasket. I then use a feller gauge to check end play. I add or remove shims for proper end play. I understand that you measured the cams length so you would assume that the shims would be the same. But if the cam you removed was not shimmed properly to begin with or the bearings seated, or ware etc., you would have improper cam end play.

I have had cams walk which intern causes the cam lobes to ware improperly from the load not being centered on the cam lobes from the tappet rollers. There is more work involved, but I feel doing it this way is the best way to preform this swap.
Could you post a "how to" w/ pics on these additional steps for those of us less inclined?[/QUOTE]

Thanks Bowhunter, I just installed my 585 cam following your instructions and it was a breeze. Now I'm onto adjusting the valves. My 585 was within .001 of the old cam width.:whoop::whoop:

The new .585 cam I installed was stamped with .592 on the face of the cam gear. The part no and box from S&S was marked correct. S&S does not list a .592 cam, does anyone have any thoughts on this?

Got a pic? More lift for the money :cheers: cam gear may have been stamped wrong....

No pic, sorry, I closed it up already and now I'm pissed at myself for not taking one before I closed it up. I've never worked on a motorcycle motor but after doing this myself with the how-to's on here, I could proly do this in 4-5 hrs again (to go back to stock) if it causes other problems.:confused:

Now that I think about it if there is a identifier stamp for the cam it should be on the cam not the cam gear.

It was right on the face of the gear along with the 2 stamped dots for alignment with the crank teeth. If it was machined to be a .585 I would think .592 is out of spec and they would have reground it to .585 unless they sell a .592, which they don't.
I don't think its any big deal just very odd.
 
Just got done with this install and the hardest part was putting the freaking pushrod tube covers back on.....fun!! This thread helped me a bunch, Thanks man
