engine Hose replacement

[faselh]

Is there a set of parts available for the mandatory 5-year replacement of all engine hoses for the Rotax 912S? For Ximango AMT 200S.

Thanks, Hermann

Lockwood or California Power Systems can hook you up. I did mine about 2 years ago. Kinda messy, but otherwise pretty straightforward. Don't forget the carb inspection/rebuild every 200 hours, too. Pay particular attention to the needle and main jets for signs of wallowing out by the needle. Fairly common on Rotax engines due to the vibration. Here's links to Lockwood and CPS:

Thank you very much. Did you attempt to get the hoses from Ximango USA?

I tried to make contact but so far no luck.

No, just call Lockwood Aviation in Florida. 863-655-5100. Tell them what you have and they'll send you what you need. Basically, it's a short, molded hose and a meter or so of metric sized radiator hose that you'll cut into the pieces you need to replace your old hoses. It ain't cheap, but it's very good quality stuff and Rotax approved.

One other thing I thought of regarding the hose clamps is Rotax recommends using "spring clamps" or "Corbin style" clamps as opposed to worm drive hose clamps on the radiator hoses.

Here's what they look like: http://www.autozone.com/autozone/accessories/Tools-Garage-and-Equipment/Hose-Clamp-Universal-Type/_/N-25vt?filterByKeyWord=Spring+hose+clamps&fromString=search

The reason is because the aluminum fittings that the hoses plug onto expand and contract as the engine heats up and cools down. The worm drive style clamps don't allow for this expansion and end up crushing the hose, which will eventually leak. The spring clamps allow the aluminum fittings to expand and contract while keeping even pressure on the hose throughout the range. There's a tool to use on this style clamp. You can get one at any major auto parts store for around $30. The easy to reach clamps you can probably get with needle nose pliers or a small pair of Channel Locks, but to get at some of the clamps you'll almost have to have one of these tools.
