These go into more detail about the tasks of replacing parts and setting internal and external timing.) The rotor contact needs to be checked at inspection time, and if a copper contact is found, it should be replaced with a Monel one (left). (Please also refer to previous KITPLANESВ® articles in the November 2013 and April 2020 issues. If worse comes to worst, you can put the parts in a box and exchange them for an overhauled magneto. And any cracking or chipping of the block-the part that receives the spark plug wires-is cause to replace this part.ДЄll of this is doable by most airplane builders, but it is a good idea to get some experienced help the first time you try it. All gears need to be checked for missing or damaged teeth or discoloration due to excessive heat cycles. You will need to check the rotor to make sure the contact arm is not copper-the arm and the gear to which it is attached need to be replaced with the new Monel arm and gear. Since you will most likely replace the contact points, you will not need to be overly concerned with signs of arcing or pitting of the point faces, but this is obviously not something you would let go unaddressed. The bearings will need to be replaced if this is the case, and it requires special tools to do it. One of the things you are looking for includes any looseness of the shaft in the bearings. The contact points for a magneto look very much like the points of the ignition system of an older car. Whenever you work on your magnetos, it would be wise to search for all service bulletins and ADs because some parts will need to be replaced if your magneto is affected. Champion service bulletins S1-15A, SB1-19 and others that may apply.

L-1363G Champion 4300/6300 Series Magneto Maintenance and Overhaul Manual.The kit costs $350.ДЇor this work, you will need these items: Champion sells a kit that includes these replacement items but does not include the gasket that goes between the mag and the engine case. Of these items, you can do all of them yourself except test the capacitor and re-magnetize the rotor. Check applicable ADs and service bulletins.Do It YourselfД¬hampion says a 500-hour magneto service should include these items: The spring is best replaced at 500 hours, and the pins that hold the mechanism together should also be checked for unwanted looseness. Here is a Slick impulse coupling taken apart. The rotation is always вЂњleftвЂќ with the engines Experimental builders typically use. This value should match the ignition timing shown on the engine data plate. The lag is also listed on the data plate. A 4373 has 25В° of lag, making it well-suited for a Lycoming O-360-A1A engine. For example, a 4370 mag does not have an impulse coupling. The model number tells you if the magneto has an impulse coupling or not. The third and fourth digits are the week it was made in that year.

The first two digits of the serial number are the year it was made. The make, model number, rotation and lag are all shown. Reading the Data TagД®ach Slick magneto has a data tag with important information. Before that happens, it is time to do some work on your magnetos. To do this work on my magnetos every 500 hours? For Experimentals, the answer is no, but if you donвЂ™t, you will likely notice a deterioration of your ignition system that cleaning your spark plugs wonвЂ™t cure. Aircraft Spruce also has the special tools you will need to work on your Slick magneto, but they can be hard to find if you donвЂ™t have the part numbers. WeвЂ™ll start with a discussion of Slick mags, the most common.ДЄircraft Spruce sells overhauled magnetos on an exchange basis with work performed by Kelly Aerospace or Champion (Slick), or you can go to an independent shop such as Aero Accessories in Torrance, California, for a more economical solution. Some of this work you can do yourself, but some of what may be needed is beyond most ownersвЂ™ ability. Lag should be equal to the recommended spark advance on the engine data plate.ДЄbout every 500 hours, your magnetos need to be inspected and repaired as needed (IRAN) to keep them performing well. The data plate on the side of the magneto will tell you the serial number, model number, the direction of rotation and the lag of the impulse coupling.
