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 The previous version was outdated and no longer supported.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

WRONG torque spec!

Why am I even surprised, right? Should have went with my gut and did a little more searching, but the engine assembly manual says 5 fl/lbs for the balance shaft nuts, thought it was very low but who am I to question the people who wrote the manual, right? WRONG! May be they wrote it wrong, maybe lost in translation, but it's wrong in 2 different places! This is why the balance shaft nuts backed out and my motor locked up! And now I need new intermediate engine cover as well on top of balance shaft (which I already sourced) Cases are together, waiting for more parts... could have bought a new one for the money I spent fixing this bike :)

Husky 610 Workshop Manual - English.jpg

my 2nd cover (starter support) on the left, melted around the bearing from when the balance shaft nut backed out and started rubbing on it.
Original one on the right with cracks from those idiots in FL (MotoCourse Performance) who did not align starter gear and forced it closed, cracking it.

here's the starter gear that was rubbing against balance shaft, thinking I might want to replace that but it has no damage on the working surface or bearing surface...

there is a comma error in the measure in pounds
70N / m = 7,2kg / m = 52ft / lb.
did not a mechanic realize this error?
the value in Nm is correct !!
 
I did not see this page till now, because I was looking for torque spec on crankshaft nut, below is the page from assembly manual, only has wrong specs with wrong decimal

I'm very sorry for what happened to you
undoubtedly in the translation a comma has not been put to the right point because no attention has been paid in rereading the manual before printing but
but
but
it is not conceivable and admissible that any mechanic or person capable of doing the job does not realize that the reported value is wrong by a decimal.
7.2 Nm can be reached by tightening the bolt with bare hands
without tools.
how do you tighten a nut so important so little?
I'm sorry for what happened to you but you can not just blame the "decimal point"
 
I removed the nut using small electric Bosch tool, seems it was torqued very low, also there is no power being transferred to balance shaft it just spins free, so I assumed the low torque setting was enough for that, still I went to maybe 25, whatever felt "tight", don't remember exact number, also thinking that flat washer with tab was going to keep it in place... And I was in a rush, did not think to check other sources....

Lesson learned, trust my gut before translated manual ;)

Sad.... really.

But a mechanic should know that an 18 or 16 mm bolt will require much more torque that 5.2 ft/lb (~= 7 Nm).

Talking with ignoring some special situations; as the size of bolt increase, required torque will increase and more or less there is a linear relation. Whereas 7 Nm is very very low and mostly required on very small bolts or very fragile/sensitive parts.

I hope u will fix it soon with not spending a lot...
 
It's getting there... slowly, took 4 month to get the head back from a friend who was gonna do a valve job in 3 days, and when I got it back it still wasn't done,
so I had taken it to someone a little more professional, took him 2 weeks, wish I did it back in November...

head installed, motor in the frame, photo taken tonight :)

Will put more info on one of the other threads when I have time
