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 The previous version was outdated and no longer supported.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

2007 TE 450 shock seal head repair?

My trusty old 2007 TE 450 finally began to weep a tiny bit out of the shock absorber shaft seal. As near as I can tell, nobody makes an aftermarket seal head for this shock. Looks like Race Tech offers up a rather expensive "gasket" kit, and OEM parts list shows some things....

So I was just curious as to what other people from this forum use to repair the seal on a 50 mm Sachs with a 16 mm shaft?:excuseme:
 
I e-mailed All Balls this morning and asked them if they were planning to add a listing for my bike. They immediately e-mailed back that they had no plans to make a seal head for my bike. About an hour later they e-mailed back to say that they thought my year model had an 18 mm shaft, but if it was really a 16, then they had a part number for me.:D
 
Keep me posted on this DD. I am doing a rear end overhaul on my 07 as well. I finally took the swingarm off after 8 years. I tried a few years ago and broke two sockets trying to break the nut loose.
 
So far, so bad.....
I took the shock apart, to discover that the seal head design of the replacement unit was different from the OEM one. I'm guessing that I will need to buy a seal kit for the original, but after removing the piston assembly and topout spring, I found that the spring bushing doesn't want to come off the shaft, even though it will rotate freely. So now I have questions. If the bushing is not removable, then I guess that I have to unscrew the shaft from the clevis end to pull the seal head, yes? If I could remove the bushing, then could I run the replacement seal head, or would it change the overall extended length of the shock absorber?:confused:
I need to do more research.
 
It is really beyond annoying how little information is out there about these shocks.:banghead: Nobody seems to know anything, and those who do know, probably work on them for their livelihood and don't want to divulge any information that might take income away from them.:excuseme:
 
So here is the skinny from a professional suspension shop: The seal head has to be taken off of the clevis end of the shaft (so a nice aluminum shaft holder will be needed), because that bushing under the top out spring has to ground off to be removed. The micro fiche for the TE 450 shows rebuild kits for the seal head, or there are a sparse few companies that offer the parts. That's about it.
 
DD,
Been doing some talking with and he just did my trials bike forks. Mike Crow, Crow performance suspension here in Jamul- he is one of the top tier Race Tech guys that now has a fully supported Race Tech satellite shop. He just rebuilt the Sachs shock for my ex 1999 TE610, he had to machine (he's also a machinist) a new seal head (he did his weekly drive up to Race Tech HQ and turned the piece up there) so he could adapt another standard seal to fit the shaft and all the assembly parts. So there is another option.
Of course I would say go after the OEM options first, then go to the next step (above). RN

So fact is if you handed Mike your shock he will find a solution either from Race Tech parts bin or will create a new component to fit and solve the issue.

Mike worked with LR on his Race Tech set ups (my ex LR TE310 had his handiwork and was a super great enduro weapon)
 
So, the shock has now been converted. Not a tiny task, but not a big one either. I ended up collaborating with Mike Crow. He did the measurements, removed the bushing, rounded the edges of the groove where the bushing clip had been, and refaced (lapped) the valve surfaces. He added the right amount of flow through teflon bushings to get the correct build length with the All Balls sealhead that I had bought. A big thanks to him for listening and helping me get the shock the way I wanted it.:banana:
