• 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 The previous version was outdated and no longer supported.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!

Broken Timing Chain

Hi, First timer. The timing chain on my 1993 610 WXE brole and the exhaust valved lightly touched the piston. The valves "look" untouched and the piston has two small crescent shaped divots. The question is whether this is an automatic replace the involved valves, chain and piston, or can I merely add a new link to the chain and put it back together.
If this is an outrageous question with an obvious answer please forgive my naivete but this is the first time I have encountered such a problem. Thank You, Bill Pierce
 
Never replace a link of any chain that breaks.

You are merely asking for it to fail in another spot, very shortly.

New chain, and probably new valves/piston too. Possibly inspect the cam for damage?
 
I think that the piston is probably fine, unless the divots are deep. Any markoff on the piston should be cleaned up to remove any sharp edges. At the very least, have the valves and guides/seats inspected.

And, I would definitely replace the cam chain.
 
Valves usually get tweaked whenever there is contact sometimes doesn't show unless leakdown test is done.
 
timing chain and gears for sure you say 93 have someone who knows whats what look it over REAL GOOD if its worn enough for the chain to break its got alota time on it or something else failed and caused that to happen fix it right so it stays fixed thats alot cheaper than doing it wrong 2 or 3 times
