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 The previous version was outdated and no longer supported.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

Husky engine failure

I initially suspected clutch hub rubbers falling out but then I saw the crank. The piston and bore look surprisingly good for 303 hours!
I see the little circular marks on the piston valve pockets. Looks like the piston kissed the valves. the valves might be bent. The cam journals in the head look good and that is expensive.

Spray some WD40 behind the valves and see if it leaks pas the valves.

yeah, I saw where the one valve hit the piston (lightly?) and forgot to mention it. I'm thinking it's because of the big-end bearing failure maybe.

a lot more carbon then i would expect too.

Well 303 hours is a lot, that might explain the carbon.

Yes, I think the bad rod bearing caused the valve hit.

Also looks like some impact damage in the head dome too.

At 303 hours I'd be prepared for some new valves and seats.
Those Ti valves are like $300 a set.
 
Thanks for all the input. I'm still waiting for the overall damage result from my local husky store...

Change the HILFO 116 every oil change around 10 hours +-2,200 hours no problem. I guess the 116 should be ok, used Castrol Power 1 Racing 10W50 all the way long.
I have ordered some parts to replace. All inner bearings/caps, assembled OEM crankshaft, a new timing chain, a gasket kit and a new piston is already here.
I will see if I have to replace some valves also.
 
Might possible flywheel discoloration results from e-starter failure last summer where sprang clutch and freewheel were replaced. The shop will check.
Can I leave the stator now a bit broken as it is or should I do something here?
