• 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 The previous version was outdated and no longer supported.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 oil screen tube orientation Q

Hi gang. I did my first oil change on the 630 yesterday, and now I'm getting a little paranoid here. Here's the thing, the Q I have:

This regards the oil screen "tubes" on the left (shifter) side of the engine, and the orientation of one. One is larger and the other fits inside of it. This latter one- the "inside" screen tube- has the screen going all the way to one end of it, and on the other end it's first smooth/solid metal for about 10 mm before the screen starts. So from this end it's smooth, for 10 mm to a "rib", then screen all the way to the other end.

Mine came out leading (meaning against the mounting plate) with the end of it that has screen going almost to the very end of the tube (so the 10 mm smooth section was furthest into the engine.) I replaced it that way.

The Owners Manual shows (or suggests) that this is the correct orientation.

The Shop Manual shows it just the opposite- w/ the smooth/solid end facing out against the plate that is bolted on holding this stuff in.

What else is diff than the book: on my bike the plate holding it in is "stepped" and has two o-rings on it. I know the end that has screen going all the way to the end must mate to an o-ring, either on this plate/cap, or the o-ring all the way at the end of the cavity. The Shop Manual shows a diff set-up (smooth cap, and separate o-ring placement.) BTW- I did see an o-ring at the far end (far internal end) of the cavity, and that appears to have to stay there.

I'm worried because I did ride it for about 1.5 hours last night and now I am fearful I may be screwing it up. It ran just fine. My thought is that the "ribs" on this inner screen tube keep it, say, 2 mm inside of the outer tube (as in "away from" and therefore oil should circulate throughout the two of them fine. Still, I'm sure they made it this way w/ a purpose, but the orientation in Husky's two publications conflict.

Please advise- thanks!

Huh, that is funny. I just looked and the two manuals do show different orientations for that inner screen.

I can't remember off the top of my head which way it goes. I use a cap from 7602 Racing on those screens that's captive. The screens only fit on it one way. So, it's a no-brainer. It's also much easier to use than the OEM cap.
 
Thanks man. Yeah, it's not much help but I can't blame you there. :) Thanks again for all your help this far!!
 
I haven't pulled mine apart yet but I appreciate you alerting me to issue. I'll ensure I take close note of how the screen tubes and o-rings come apart from the factory.

Yes, do that. I did also, but then I started (overly) looking at the two diagrams (one in the owner's manual and the other the shop manual) that confused things. Oh well, according to the guys on adv I seem to have it right, so all good.
