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 The previous version was outdated and no longer supported.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

Te449 Timing Chain Slack

When re-assembling the cam shafts on my '13 te449, there is a considerable amount of slack on the timing chain even with the chain tensioner installed. Before disassembly of the top-end, it was very tight, so I don't think this is a worn chain on a 5k mi bike issue. I checked that the chain is still on the crankshaft sprocket and is sliding against the slider rails correctly. The tensioner piston is in the default fully extended position. Totally scratching my head...

Appreciate any thoughts you might have.

Thanks,
Jon
 
Hard to give a solution without having the engine here. Its not a worn chain so dont bother about that. Have you had the tensioner apart?
 
Thank you for your response Soderberg and I totally understand the challenge of troubleshooting over the net. I ended up figuring out the problem and I'm a bit embarassed to admit it. When I took the head and cylinder off, I must've let the timing chain slip enough that it came off the crankshaft gear, which explains the extra slack. Looking down from the head with a flashlight, it appeared to be wrapped properly around the gear. This is the first time I've ever looked inside an engine little alone take one apart. It is now back together with the proper tension on the timing chain. Thanks again.
