Eisemann mags & parts

[geneL3c]

Looking for Eisemann AM-4 /LA-4 mag drive gears and impulse couplings for A-65-8 . C-85-12 impulse coupling will NOT work . Will consider complete mags as long as they have the gears and couplings . May have parts to trade if I have what you need . Gene

You and me both... been trying to find the impulse couplings / starter / etc. for the A65. No where to be found... Seems the supply out there is counterclockwise rotation (C85-12 etc.) and the clockwise stuff is.. hmm.. still on planes somewhere. I have 2 great mags for the C85, no gears, but they rotate opposite...

There was a guy on eBay not too long ago selling a bunch of couplings, never responded to my email about A65 ones. Will email him again..

Contact Arn Air 712 651 2255. He still works on Eisemann mags and has some parts.

call Fresno. They repair Eisman and have parts.

I have three Eisenmann mags for an A65. I'm thinking they came off my old engine (many moons ago) but I have no idea why I have three . Anyway, one with the impluse coupling and gear and the others with just the gears. I don't get any spark when I spin them so expect they're only good for parts (or maybe the points are just corroded but I doubt it). I was just going to put them on EBAY but make me a fair offer (????) and they're yours if you can use them. Contact me by PM would be best.

Gene, our EAA 100 board met last friday and decided that the public should have the opportunity to buy anything that our AI gave to the chapter first. If you want any of the items on our web site let me know what you want to pay and I will bring it up to the president. I don't believe we will have much interest but let me know - shoot me a number and I am sure they will be yours............Gordy in Minn

Gordy,

Do you have a link for the parts you are selling? Just looked and it showed "tools and parts from Walt Mounts time as an A&P" but the link did not work.

I am looking for sheetmetal parts, like rivet squeezer and bits and so on...

Thx,

Joe A

Gordy , I'll have another look at what is on your website and see what I can use . Give me the link again , if you would , I'll let you know as soon as I can , thanks , Gene

I finally got around to rebuilding a few Eisemann mags after many years not flying. Here's some tips for those folks looking at rebuilding or just getting a used mag installed - I luckily found an A&P willing to advise me after he stopped doing Eisemann rebuilds.

Changing mag rotation: If you have a mag for a C85 or so counter-clockwise that has all the same parts as the clockwise version (H27-709 (C85) and H27-711 (A65) for example), you can change the rotation easily. Here's how: open up the mag (5 screws - 3 in the case, 2 on the top plate where the wiring harness attaches). Take off the next mid-section plate you expose after pulling off the outer case (5 screws I believe). Take off the small pinion gear that attaches to the distributor (larger) gear. Slide off the Woodruff key that holds the cam and pinion / rotor together, and take the oval-shaped cam off. Flip the cam upside down (there will be slots facing toward you now that were hidden in counter-clockwise mode). Now rotate the distributor gear until you have the furthest left timing mark (there are 2 timing marks in the plastic gear about an inch apart, they look something like this -C and another mark is the reverse of that). You have to now align the little drilled (1/8"?) hole on the outside of the pinion gear with this mark. Now just put it back together and you'll be running clockwise (likewise, if you were converting an A65 mag to run on an C85 you just reverse these directions). Can't believe no one has ever posted this...

Winding an impulse spring: okay there are not Eisemann tools for this available anywhere, so you have to be a little creative here. I made a tool using a 6" 1/2" galvanized pipe fitting, a 1/2" T fitting for leverage, and a jigsaw. All you do is screw the 2 pipes together, then on the 6" piece, cut a notch with a metal jigsaw blade about 1/8"-1/4" wide so that the impulse spring center coil can slide in. Once it fits, push the outer part of the spring into the cup spring slot, then take the tool and rotate the inner spring coil until you can squeeze it into the starter cup. The direction to wind is opposite the mag rotation desired (i.e. A65 wind counter-clockwise). If it keeps slipping out, either use your hand to hold the spring end in the starter cup slot or put vice grips over it with a protective piece of copper or lead to avoid damaging the cup - be sure this piece of metal doesn't extend into the cup though otherwise you'll have to wind it even tighter to fit the spring in. Once you get the spring in the starter cup you can just align it with the flange (keep the paws inside) and wiggle it down into place on the rotor shaft. FYI new impulse springs are only $6 at Fresno Airparts.

And to convert an AM4 to an LA4 isn't very hard (i.e. unshielded to shielded mag conversion for radio interference)- you just need a few parts from a used LA4. Just swap the distributor cap, the rear case with cover, the small middle section with ground plug, and finally the "high tension terminal plate" H27-675 and you're good to go. Of course you'll need a shielded wiring harness as well (~$140 from Fresno Airparts built to your specs, unless you have a spare harness you want to convert over).

Another FYI most of the Eisemann parts in the AM4 and LA4 and even LA6 mags are the same... so if you're trying to get a mag working again you can basically buy any of them used and swap parts out. The parts manual I have saved to my computer I have no idea where I found it but if you email me I can send your way. The only thing that really changes between mags is the rotor size, impulse mag coupling assembly, and the distributor cap.

All I can say is that if you have Eisemann mags or want them, you CAN get them operational for not much $$$ knowing the above. I BTW have tons of spare parts for anyone looking to rebuild I can sell them much cheaper than what you'll find online since I don't actually need most of them... yet... -Matt

Hey mslezak! Your post was great I just overhauled my C-75-12 magnetos most of my parts I got from Fresno, for future reference are you still selling parts, my condensers were kinda old and hey flashed really slow, I have a shielded harness in pretty fair shape, one question how heavy is your shielded wire that goes to the mag switch, I don’t have a rotary switch on my Champ I am using two toggle switches. Originally my mags were always shielded.
