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 The previous version was outdated and no longer supported.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!
7602 & zipty racing sell parts that have known issues! Don't buy!

This is cafe Husky. Not Huskys Customer service.
That being said...ALL and I mean ALL get back on a way to help. If you don't have something nice to say.....
That goes for all. No more POS...no more 7602 and Zip Ty are bad....no more I will buy it from you for a criminal price. Enough. This is not the roots this forum was found on.
Everyone got the rules? I hope so.
Now the problem.
If said...remeber I am as others trying to help. The magura is not the best hence 7602, ty, making aftermarket as well as Husky going to Brembo for new motor (no it won't swap) O ring and X ring are not same and compatible (some pistons use it..others don't)
Any ligh oil will work Mineral oil is cheap and any drug store will have it for $4 in the laxative aisle. best to bleed from bottom up and with slave cylinder off bike and be careful not to pump up too much or piston will pump up too much and circlip will crack out of groove and take away the metal on the stock unit. (thats why Ty makes the replacement...stronger and beefier than the stock...also like ony 100 bucks!)
I had same problem and it was not anything other than the stocker cracked and piston walked all the way in. used the zip ty and stock piston. All fine since. I "heared" ty had some early units that had a tolerance issue back in early 09 but cannot confirm or deny this but the same source told me he gladly took any one back and sent a new one no questions asked. I have many 7602 parts as do many friends and never any isssues there.
Again, ALL..help here...no bashing...no cussing...no whining...no smrt alec comments at someone who just wants to ride. In case I missed something...read the Cafe Husky Forum rules.
Thanks all and lets get this SM ripping up the streets of TX

You don't want help, you already have TT as your soapbox, and I've been contacted by several people in a variety of ways suggesting several things. The bottom line is I really don't have time for this and no one else wants to read what you are typing.
Good bye.
ZipTy is the US race team for husky and 7602 is one very nice a cool guy (Clay), your convincing no one. Several of your posts have been responded with concise info on how to figure your problem out and you just want to blame people. Both these company would surely give you your money back and try to help. That i am sure of. The way you are going about it makes me think any phone calls ending in clay telling you to F-off was because you were being unreasonable like you are here and in MANY other posts.
As i engineer hydraulic systems as well i can tell you it is not rocket science. A hydraulic system works on simple principles and all that is needed is correct dimensions for the type of seal used. These are published specifications. So here is whats wrong with your system. The master is probably fine. Usually is. The hose seems to have gotten loose at the fitting at some point from the removal and reinstall happening many times. The Ty or 7602 piston, which i have never seen, may or may not be dimensionally correct but i am guessing they are as i know many happy customers of the 7602 part. So the critical thing is is the slave bore round and straight and the right dimension? Thats the starting point. If determined this part is right the 7602 slave piston and seal should work as described.
1. determine if the slave cylinder is round and straight and in spec
2. Make sure the end retaining the piston is not broken from bottoming out like many can do breaking the clip land at the far end.
3. Look at your push rod that actuates the clutch pack. If this is damaged on the end or warn out it will be to short and cause the piston to travel to far and bottom out braking the end off the slave cylinder.
4. Call 7602 and determine if the slave cylinder dimension sound right and if his piston is in spec. If so install.
5. Back bleed the system.
As i said this is a simple system and if it leaks it is 100% because the bore is out of spec, the piston is out of spec, the seal (o-ring or X-ring) is not right or needs replaced. Thats it, your problem is there and should be simple to fix. It is for sure one of these three things that is wrong. Concentrate your efforts on the bore, piston and 0-ring, thats your issue. Work with Clay to determine these things. The time and effort you have done here on other forums bashing companies and ignoring calls could have resolved this by now. As I said hydraulic systems are basically simple and have been used for a LONG time with dimensions that work.
Time to get out of your cloud of negativity and address the semi simple issue at hand. You have burned most the bridges that would have been bending over backwards to help you had you just concentrated on the issue at hand instead of bashing those trying to provide solutions.
Check these three things, bore, piston, o-ring and get this problem fixed. Good luck.

+1 to Kelly's comments above. I would also double-check the oring to ensure there is no small nick or crack. If you are hasty with installing/removing (such as with a pick or small screwdriver), you can damage it. The smallest hint of damage is a no-no for oring seals.

Wow...just wow....
Never used Zip Type products but am sure they work great, I have used Clays Products and I can say he's a stand up guy who does great work...

Ok, well I finally have time to respond to this thread. As stated in another thread by me. Here is the direct quote so you don't have to go searching for it.
The first run of clutch slave cylinder pistons that we made had a slightly looser tolerance on the x ring groove. .001" diametrically to be exact. For those not familiar with those types of sizes, that is about 1/3 the thickness of a sheet of paper. We made a handful of prototypes with this same x ring tolerance and sent them out all over the world to be tested by husky riders. We tried to target hardcore racers the most as they are more abusive on things, but we also sent a handful out to just regular Sunday riders. Not one report of leaky pistons came back during the testing phase so we went into production with those tolerances. A few months after this first run of pistons went on sale we began to get a few reports of pistons not sealing properly. The number of reports we got gave us a failure rate of about 3.7%. All the pistons from the first run were sold by February 2010. In every single case of a leaky piston we received, the piston was replaced with a 2nd gen piston absolutely free, or the customers money was refunded. I have even sent out free replacement pistons to people who didn't even buy from us. They were bought through a dealership. In the 4 production runs of pistons I have made a total of 2 refunds, and will apparently will soon be making a 3rd.
So to summarize, the first run of pistons made before August 2009 and sold before February 2010 had scattered reports of leakage. The design was modified in February 2010 and all subsequent runs of piston have used this tolerance. I have never, nor will I ever sell a product I know or suspect to be defective. It absolutely disgusts me that I have to write this. I have worked extremely hard over the last 4 years to build 7602 from the ground up into what it is today. I treat customer support and satisfaction extremely seriously. I thought that level of dedication and commitment was apparent to everyone who has dealt with me personally, but I guess it still needs to be stated. I have always and will always do whatever I can to make a customer happy with his/her experience with 7602. If anyone out there in internetland has a question/problem/comment about any of our products my contact info is listed below.
Now, to Evoxbobby specifically. If you haven't already given up and parted out your bike there is one last thing you might check. The crankcase breather hose leading from the top right side of the valve cover to the air box has been known to cause clutch loss. Check this hose and make sure it isn't blocked, pinched, or melted closed. An obstruction of this hose can lead to a buildup of pressure in the crankcase and this can cause the clutch to malfunction. Good luck.
And to clarify, who ever it was that you called and talked to at 11 and told you to go F yourself, it wasn't here. The last time we spoke was on 12/02. You are confusing us with someone else.

My take on this is that EVOXBOBBY was simply frustrated with his problems and was much more interested in having a platform from which he could vent from than he was in actually getting his bike fixed.
Several of our members tried to give advice and it was summarily dismissed in favor of complaining and ponting fingers.
7602 has always been a stand up outfit and now that Clay has had an opportunity to respond to this I see no reason to keep this thread alive.
