• 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 The previous version was outdated and no longer supported.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 hydraulic clutch to 610

Hi,

Any 630 owners who has or cares to take picture of clutch slave cylinder mounted
in left side of crankcase?

Reason I'm asking this is, that I'm planning installing 630 hydraulic clutch to 610
and I'm interested in how tight the tolerances are in mounting bolts.
 
This thread has some real close-up shots, and further down a shot that's a little further away.

Now I don't have a 610 and may be missing something but the real difference is in the engine casing/casting and overall design of the clutch actuator. The 610 has an actuator arm for the clutch, naturally, so you'd be looking at a hydraulic conversion set-up. This comes with a totally different slave- one that mounts where your fixed cable end/housing mounts just forward of the actuator and moves your stock actuator. That set-up will look something like:

BTW- I know nothing about Venhill- just grabbed the first illustration I could find.

As Eric's written, the 630 hydraulic sytstem shouldn't work on the 610.
On an Italian forum (which doesn't exist any more) a guy posted his experience with this kit: http://www.htmracing.it/cms/index.php?option=com_content&task=view&id=113&Itemid=118&lang=en: he didn't manage to install it properly and so he shipped it back and got the money back. I don't know whether the fault was his or of the hydraulic kit.

Of course it's not direct swap as plug and play, but with a little milling and welding it should be doable.:D

Personally I think it's a very ambitious task, though I admire your optimism. I'd say study the diagrams and pics (and internals) of both the 610 and 630 casings very carefully to try to determine if it's even feasible. It's also a "grass is always greener" thing (or at least a different set of pros and cons) as, every time mine leaks, I'm inclined to lust for the simplicity of a cable system. I know the system on the 610 is notorious for eating cables but, from what I understand, if cables are routed/aligned straight/just right- and adjusted appropriately- then it's a pretty reliable set-up.

I don't have 630 case available, 610 is open in front of me. Already talked with welder, who agreed that it should work, if the cylinder fits there. I think the stator side is quite tight on the 630 also and IMHO it is similar as 610.
 
George Erl at Uptite Racing in Santa Ana, CA has the Magura Hydro conversion kits for the 610. I got one and installed it over a year ago.....muy bueno!
