|
I've had a 912UL sitting in my garage for 9 years in basically the
condition it came to me from the factory. My garage is air conditioned
as part of the house and the humidity here in Oklahoma is usually less
than 45 % dropping to 20-30 % during the winter months.
I have begun work to finish the last 20% of my Kitfox IV construction
and need to know what I should do to the engine.
Does it need to go to a Rotax service center for teardown, or is it
likely to be OK to use as is?
Also, do I need to replace all the hoses that were put on it back then
(fuel, water, oil)?
Anyone with experience like this?
Thanks for the advice,
Clem

Clem,
I am in the same situation. My engine is 10 years old and had never left the
box until two weeks ago. I called Lockwood and asked Kerry the same
questions. Regarding the internal stuff he said look in the spark plug
holes. see how it looks. If you remove the gear reduction you can see into
the crank case. I did this because I was putting in the vacuum pump drive
gear. One thing I did was put oil in the crankcase (1/2 to 3/4 quart) and
roll the engine around. I mean physically roll it over. My main concern was
the lifter faces. Then I took out the spark plugs and sprayed LPS 3 in the
cylinders and hooked up a battery and cranked it. I got the oil in by
hooking clear plastic tube to the oil inlet and pouring oil into the tube
until I had enough in the engine by hand cranking. Then I hooked the tube to
the return. People will tell you it won't pump with the spark plugs out, but
it will if the pump is primed.
After doing all of this I feel reasonably confident it will be just fine.
There are however some Service Bulletins and Letters you may need to look
into.
1. Stator (not bad $100+) (special puller)
2. Rocker arms (expensive, $800+) (special tools)
3. Carb floats
4. Dipstick
There may be more. I have the special tools if you need to borrow them

Brett,
I am familiar with the Service Letters on Stator and Rocker Arms but have
not heard about Carb Floats or Dipstick. What are those about?

Can't find the floats but Lockwood said I needed 'em.
