|
|
I have a Rotax 912 engine in my 601XL. One of the oil hoses will leak where it connects to the oil cooler. It's a relatively new hose. I've retightened the clamp several times, but it will leak again after a few cross country trips. I've even replaced the clamp with a wider, stainless steel clamp with an internal sleeve.
I think it's a case of differential thermal expansion - the rubber hose and the stainless steel clamp don't expand equally - which deforms the hose over time ("cold flow").
I was thinking of trying a Breeze constant torque clamp (http://www.breezeclamps.com/ct.htm) and tightening it to about 40 inch pounds.
Has anyone else run into this sort of problem with hoses and was it solved using a spring clamp?

We use the breeze clamps in our turbo kits with good success. Probably
the ultimate in self adjustment would be spring clamps like the
factories use on modern cars. Can be a pain to deal with, but work very
well.
