Lightspeed/Lycoming 4 cyl direct crank install

[AlexPeterson]

I forgot to mention one important thing - at least on my O360 - you will need to push out one of the threaded prop mount bushings to get a straight shot at drilling and tapping. I used a large c-clamp and some metal bars to push it out.

The larger magnet idea sounds like a very welcome change, I'd go with it.

They might also be willing to drill the crankcase bosses if you need it; can't hurt to ask. Check out the thread on Lightspeed Wiring Specs, too.

Will do... this is starting to look real good. Thanks for the input everyone.

I was thinking at least one would need pushing out. Should I order a new replacement? (as in one time press fit)

A jig... now that's a great idea! I can see how this drilling process could be very critical. I would love to have a jig. Will call... asap tomorrow. Also now have an F1 Rocket builder in line to help me out.

Thanks!

Let me be sure I didn't give you the wrong impression. They don't sell the jig; it's a one-off machined tool that they use when they do LSE installations. You could get one made up at a machine shop but it would be prohibitively expensive for a single use. I was suggesting that you ask them if they would be willing to drill your flywheel and crankcase.

I take most are getting the Lightspeed EI installed by an engine builder, not as many replies on the thread. I guess that's one good way to do it... My friend is actually an EVO F Series Rocket builder, relieved he states this is a piece of cake. I hope it all works out well... I'm sure it ill.

I spoke with Klaus today and learned that the 1/4" magnet is now his "in shop" install. He stated that he no longer installs the small magnets. He still ships out the small magnets and drill bit with his EI kits for builder installs. My flywheel should be drilled and on its way back Thursday.

Thanks again Radomir!

Alex,

The flywheel is back, Klaus did a great install... tight level fit for sure. I also received a document with the install that states:

"When using 1/4" diameter magnets, maximum magnet to sensor surface/skip plate gap can be as much as 0.110". The minimum clearance of 0.030" still applies".

Ah, should be a lot easier to setup now. Also, this magnet setup will run dual Lightspeeds later if desired.

Thanks again everyone!

who is Klaus and where can he be reached. I rechecked this thread and didn't see and address listed. Thanks!
