Part 2
For those who have decided that they will do a Rotax 5 year rubber replacement we need to look at what it covers and how we can utilize good sterile maintenance practices to keep debris from our hose lines. I will admit that there is more than one way to accomplish this procedure and what will be discussed in this article is, but one way.
The Rotax 5 year rubber replacement covers all fuel, oil and coolant lines. It covers any V-belt, carburetor diaphragm and carburetor rubber intake sockets and any other air intake rubber hose or tubing. With the new maintenance manual just out the fuel pump has been added as a replacement item too. So now you need to decide what brand hose you are going to use. Should it be fuel injection hose or standard carburetor hose? Since we are dealing with a worldwide distribution for engines the hose selection can be vast, but by all means should be thought out. We need to decide what tools we are going to use to cut the hose and how we are going to secure it in place. These again will vary depending on your geographical location.
The prudent answer is YES and absolutely !
At the same time you pick up a screwdriver or wrench and get ready to perform some work on your trusty Rotax engine, be it a 2 or 4 stroke, you should also be reaching for your engine manual. Let’s face it a manual is as important as your wrench. Your neighbor is not a walking Wikipedia and won’t always provide the correct advice or at least perhaps not in correct sequence.
Engine Stumbles on Takeoff!
In my many years of flying I always like to think I’m prepared for a pilots worst nightmare, engine failure on take-off. Until it happens to you, one never knows just how prepared you really are! In this particular case, the engine came back and the pilot made a successful landing, but that momentary sputter really got his heart beating. The real question was, why did the engine stumble, then come back to life?
