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 The previous version was outdated and no longer supported.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

630 Cam Chain Tensioner

I'm working on replacing my cam chain and pulled my tensioner, thinking I could see how many clicks it was out.

This one is different from the 610. There are no clicks. It relies solely on spring pressure to tension the cam chain. So, pulling and checking it is not really a feasible method of checking for chain wear, like it is on the 610.

There is also a paper gasket on it that is stuck on there pretty good and appears not to be reusable.

I didn't get any further than pulling my valve cover and stator cover. My 5 year old son has a fever and he's being pretty high maintenance tonight. Oh well, I like the cuddle time. :)
 
No clicks but you can hold the screw when removing to see how far the tensioner has extended. Then completed release screw and tensioner will fully extend. Compare the two to get a ballpark estimate of where you are for remaining adjustment.

Reuse the gasket. If stuck pretty good then you should have a good seal.

My gasket tore a little. It'll probably still hold, but I ordered one just to be safe.

I think you need 4 hands to hold tension on that thing while you remove it. :)

It is standard gasket material that you can find at any auto parts store. Not too hard to cut your own with a sharp exacto knife.

What I did was first expose the tensioner screw, then remove both bolts but keeping constant pressure on the tensioner so position of plunger doesn't move, then once bolts out get the stubbiest screwdriver you can find so you can hold the screw and tensioner at the same time. Then I pulled out the tensioner noting how far the plunger was out first and then after released the screwdriver to see remaining possible travel.

I just did that tonight. I had a pretty good amount of travel left in the tensioner. I'd say a bit more than half of it was exposed.

Valves are in spec. Got the cams out tonight. Hoping to get the cam chain and associated parts at least removed tomorrow.
 
Wait till you try to set the timing, when you get TDC, mined seemed to be between 2 teeth.
I can see why the Husky mechanic got mine wrong. He even had the intake gear 1 tooth off, thats the easy part to align.
 
Didn't have a crescent wrench big enough for my flywheel puller. Wasted most of my wrenching time going to buy a wrench.
