Its been five years on our 914 so we're looking at changing hoses. We'd like suggestions
from those that have done this on how to do it efficiently and without
making a huge mess. Access to the water pump hoses seems difficult with the
exhaust system in place (muffler lies under the engine).

JMO,
if the hoses are still in good shape, I'd consider just going "on condition" on
them and leaving them be.
I recently hit 5 years on my water tubes on my 912ULS and decided not to change
them. They're still pliable with no cracks, etc., so I think I'd have just been
changing out some perfectly good hose with some other perfectly good hose and
that's about it.
I did change my radiator hoses not long ago, but those were visibly beginning to
deteriorate.
One diagnostic to check for is black residue in the bottom of your coolant overflow
bottle. If there's a lot of it after just a short period of time, something
is beginning to rot and its probably the hoses.
That's the diagnostic I'm using on my old water tubes; if I see a bunch of the
stuff at my next check (I did a thorough cleaning of the bottle after changing
my radiator hoses) I'll probably then go ahead and change my water tubes regardless
of how they look.....

Hi Jim,
In some cases this task will take a little more time than others depending on how
the engine is mounted in your particular plane. You may have to remove the
exhaust to get at the bottom hose and unfortunately some mess is unavoidable.
In my CT I will have to pull the engine out at least part way to get to the hoses
against the firewall behind the engine. The only suggestion I have is to start
with one set of hose and just remove and replace. You will need some band
clamps and a set of band clamp pliers. Try "Chads ToolBox" or a company call
"Jegs" on line for these. Your best bet for hoses and rubber carb parts is from
one of the 3 Rotax distributors. CPS, Lockwood and Leading Edge. For the
CT it is a 2 day job. If you have hose ferrules that secure some of your hose
use a Dremel toll with a cut off blade to slice them open then you can just pull
the hose off. Use a band clamp to re-install the new hose. I use the single
ear band clamp as it is easy to install and easy to remove when the time comes.
It meets ASTM standards. You should use a band clamp on the firesleeve, too.
Starting in 2011 and through 2012 there will be a pile of CT's to do in the
US. Close to a couple of hundred.

I'm not sure on the use of the Dremel tool. Especially in my hands! I use a
old =0Alarge dull screw driver (curved by intention) and just slightly lif
t up the =0Aedges of-the hose and spray WD- 40. Move to other reachable a
reas and do it =0Aagain and then massage the hose (lightly bend --twist).
The hose will easily =0Aslide off. This works great if you plan on reuse.
Also will aid on putting new =0Ahose on. =0A=0A=0AGeorge=0A=0Ado not archiv

Hi Jim,
Never reuse any of those ferrules, especially if all you did was slide them off.
A Dremel is very easy to use with a cut off blade. Just slice the ferrule from
top to bottom at two places and open it up some with a screwdriver. Just slice
the ferrule you don't need to go deep enough into the hose itself. Then pull
the hose off. Toss that ferrule in the garbage. Use a new band clamp so the hose
can not just be pulled off by hand.
