With the gear installed and tight the whole cam still moves in and out a lot. Don’t seem right. Vid attached

 

I need the same exact Harley thrust washer 8986 which is the one included in the roller bearing kit to use on the outside between the cam gear and bearing. I measured that play I have and it is exactly .062”… the same exact size as that thrust washer.

Someone had the exact same issue here on a 1999 woodruff keyed cam when upgrading to the roller bearing and this was the fix. Splined cams don’t need that extra thrust washer.

 

Sounds like you got it.. I've not done keyed cams only early 2000s which had the spline..

 

Very glad I took the time to research this one…. It would have been catastrophic!

 

Here it Is. Exactly what I am dealing with (1999 with Andrews cams and sprocket and now a “upgraded” rear roller bearing). Need that .055 spacer for the outside of the bearing and then all should be well.

 

Ok I got the .055 thrust washer in between the outer side of the bearing and cam sprocket gear now. With the gear torqued on I still have a bit of in/out movement of the entire rear cam assembly (with the tensioner shoes not contacting the chains). If I were to push on the rear cam towards the engine this would put the rear cam out of alignment with the front cam.

With the tensioner pads down in their positions there is no in/out play. I still don’t like it since with the original setup with the “problematic” ball bearing there was NO in/out movement…. Now being a roller bearing it has a “floating” inner race.

Should the rear cam have some endplay? I can’t find this info. My sprocket alignment is perfect (making sure the cam was not pushed towards the engine).

I also found a Zipper’s article stating the use of the second .055 thrust washer PN 8986 like I installed here when using a keyed shaft cam… I think I will give Zippers a call tomorrow to see if they can shed some light on my situation:

 

You are going to have some end play on the rear cam. Nature of the beast when using a roller over a ball. There has to be some clearance.

 

Bike runs fantastic guys thank you. Nice and QUIET with those new S&S lifters. Video attached hopefully it works
