  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

250-500cc Side Exhaust Valve Removal?

I'm finally getting around to stripping down my 300 cylinder to get it sent off and plated.

I've run into an issue though, how do you remove the side exhaust valves from the cylinder? They've got a bearing pressed in on top, with nothing to pull on. So, I figure you've got to press them out from the inside somehow, but how would you go about this without damaging the cylinder or bearings? My other thought was maybe with plenty of heat they would more or less fall out, beings when there are retainers that hold these in place when the engine is all together (I cropped them from the parts image below).

There is a 6x1mm threaded hole that you can screw a slide hammer adapter into.

I took another look, and yep, you're right...well mostly. It looks to be 5x1mm rather than 6mm.

Not sure why I didn't think about that, but makes perfect sense. Thanks.
 
And another update...that'd be a 4mm bolt...picked up a nice shiny stainless steel 5mm bolt and washers to fashion a puller with (combined with a flat block of aluminum with a hole drilled through it), and get home and the dang thing is still too big. :banghead:

Oh well, the 360 is back to running pretty good again, so maybe the 300 will sit in it's box a little longer.
