Further to this - used parts in good condition would be fine too. Anyone got a
used but unwanted tail spring and tailwheel fork in good condition?

I am after the door width increase fiberglass parts. Any one who has a set gathering
dust on a shelf? Either for purchase or to fabricate molds from.
Thanks

Subject: | Coolant Hose Routing |
Hi All
A quick question on the routing of the coolant hose from the collector pot south
to the radiator.
My 912s as supplied has the collector pot sat on top of the crankcase (with the
little rubber pad). The outlet faces directly aft towards the firewall.
Having fitted the ring mount, I know find that the one inch (25mm) outlet for the
coolant pipe to the radiator is at the same level and about one inch from the
ring mount making the fitting of any coolant pipe impossible without some serious
relocation of the collector pot.
Anyone else had this problem?
I might be able to raise the pot high enough to go over the ring mount or the other
option is to rotate slightly and take around the port side of the upper part
of the ring mount, but this looks like it might conflict with the port carb.
I am not even going to mention the water pump pipework - did Rotax design this
mount to fit their engine?
Anyway, water pump and lower hose routing now sorted thanks to previous forum posts
from Bud and others.
But this upper coolant pipe is proving to be a pain in the backside. Even if I
do get it over the ring mount, it looks tight to get down to the radiator past
the Europa engine frame.
Any advice?

Kelvin - I also had problems routing the C04 hose. I started with it going down
the outside of the engine mount adjacent to the footwell, but later decided to
move it in board of the mount, because it was too close to the air filter. Here
are links to some photos of my installation. The whole setup is not typical
of a 912S installation as I am using Nevs cowl and his baffle arrangements (but
not his mount). So, I dont have the usual plenum chamber for the carb intakes.
But I think the C04 routing issue arises anyway - there is barely room for
the hose between the mount and the footwell.

Kelvin,
I've never had a great deal of difficulty but as you are well aware, we all have
to adjust things around to get everything to fit. It is a game of fractions
of inches.
In installing the ring mount, I modify the angles on the water pump inlets from
cylinders 2 and 4. I personally run them through the V. I do a considerable
amount of preplanning before I mount anything anymore. Blindly following instructions
in a hope it all fits has never worked out for me on any of the homebuilts
I completed. I'm not a mechanic, I'm a dumb old pilot with an engineering
degree that has learned almost everything the hard way. Take notes, take
your time, trial fit everything. I use many 3/32 clecos to keep the holes small
when fitting.
On the one inch hose coming from the top of the spider to the port side cooler
inlet I do the same for the 912S as the 914. I carefully measure and mark the
hose from the spider to the inlet area of the port carb and airbox. I install
the 1 inch hose after cutting so the hose lies right on top of the ring mount.
I slip on a piece of hose to the M10 bolt threads attaching the ring mount
to the engine frame to prevent chaffing. I normally do not bolt up my duct until
I run the one inch hose down to get the clearance I want from the engine
and firewall studs. Once I have the hose planned, I fix the duct where I need
the nipple to fit. I then fit my duct. With the duct all clecoed final in place,
I then cut my hose.
I have one 912S aircraft that required me to take the hoses off the spider and
slightly elevate and twist the spider to fit the 1 inch hose exactly where I wanted
it to go. Alas, I had to buy a short piece of 17 mm hose from Rotax as
I needed #3 upper hose to be a bit longer. I did not put a block under the spider
tank. It hangs on the hose and has worked for many years. I'm attaching
a photo from a complaint I had with my painter on that particular plane. Rather
dusty engine with a lot of overspray which I later made him clean but it shows
the upper hoses and how it laid. See attached.
Finally a technique on hose access. I make my side supports that hold the duct
up with holes on both sides for easy access to the clamps. I actually modify
the port brace to allow the duct to slide up and down past the muffler for a
quick duct drop if needed. Of course, nut plates everywhere in the firewall/footwell.
That makes for much more comfortable duct removal.
I have made modifications to the rudder return spring holder bolts to protect the
rubber down pipe where they interfere. Normally an acorn nut on the end of
the threaded bolt for a smooth surface touching the hose if it is only close.
If really tight, because the duct is placed too far aft, I fashion a piece of
aluminum as a protective buffer. If the duct was moved too far forward or back,
I sometimes just repair and move it. It happens.
Best Regards,
Bud Yerly
