BlackandYellowBanshee Posted April 1, 2018 Report Share Posted April 1, 2018 So I ran a dyno session and while on the dyno, my coolant hose that runs to the clutch cover came off. Now I wasn’t there to see if it had excessive pressure behind it to push off or if the clamp loosened from vibration and slipped off. I’m using a silicone hose on a direct drive cover. I noticed the direct drive cover’s lip to secure the hose isn’t as aggressive as stock and it’s polished, making the hose easier to come off. The hose came off on the 3rd run. The shop re-tightened the clamp and proceeded to run another 7 pulls with no issue. Next piece of info.... this is my second dyno session Iv had on the quad. The first session I had zero issues and the quad was ran hard (about 10 pulls). Motor was leaked down after break in and after the first dyno session. Passed each time with zero loss. The hose clamp I’m using to secure it is just a cheap hardware store screw type ring clamp. I guess my question is... do I just buy a better clamp and quit worrying about it or is there something causing pressure to blow the hose off. It only happened once, but I’d rather get the problem fixed if there is one before I’m stranded and have to be the guy walking back to camp. I just can’t figure out why it would go a full session no problems. Then on a second session... come off and then be fine once retighted. Will vibration really cause those rings to loosen that much?

JUSTWANNARACE Posted April 5, 2018 Report Share Posted April 5, 2018 (edited) On a direct drive polished cover sand the water neck. Also look at the bottom of the water neck and make sure the casting meets up(sometimes the castings a little of and needs addressed), that will cause issues also. Especially with the silicone hose Edited April 5, 2018 by JUSTWANNARACE Quote Link to comment Share on other sites More sharing options...
BlackandYellowBanshee Posted April 5, 2018 Author Report Share Posted April 5, 2018 Yea. I thought about scuffing it up a bit. I’ll definitely get on that. I was hoping that was the problem. Quote Link to comment Share on other sites More sharing options...
