Cam Endfloat Mod

[49er]

Hi All
I have recently completed a "Camshaft Endfloat Mod" document that applies to all the 2 valve GS models.
It is a word document and has been sent to this site for storage "In the Garage", if/when accepted by the administrators.
There is a delay in site administration, for obvious reasons, so in the interium, I am making the document available directly to members.

If you are currently planning/doing a top end rebuild and want to take advantage of this opportunity to remedy excesssive cam endfoat while you have the head off, you can PM me with your email address. I will send the document on to you directly. If you don't wish to do that, you will need to wait until it gets parked somewhere on site. This document comes free of charge and has been moderated by three other site members.

Cheers
Ian

Brian, thanks for making this document available through your site.
By setting it up on PDF there has been a reduction in photo clarity from the original document. I will still forward the original word document to those who PM me for it.

Great job on both the mod and the write up. Looks like a good bit of thought went into this project and it’s great that you are sharing.

Not trying to diminish your solution but was wondering if you considered a simple donut shim that would fit over the end of the camshaft butting against the existing thrust surface? Would be quite thin thus I’m not sure about durability though. Anyway, just wondering…

Thanks for your support.
In my case, the shims would have measured 0.0035in inlet and 0.0045in exhaust. Shims that thin would not have lasted the distance. Also, how would you feed them past the cam lobes to the thrust rings? I am open to suggestions for improvements to the mod though.
