Overview

Aluminum CNC tool manufactured in Alaska for simple and perfect magneto timing.

Very easy to use! Simply position engine on #1 TDC compression stroke. Lube grommets. Put this tool on the top two propeller nuts and sight down top case halves to see exact mag timing. Now there's no need for propeller protractor cones!

Applications

  • Direct drive sand-cast engines

Specifications

  • Place Magneto Timer over the prop nuts and slide down the casing split to set the timing.

I saw an ad for this in the Cessna Pilot Association magazine and the ad said the tool for the 470/520/550 was also for the IO 360 ( which I have on my R172K Hawk XP) . Turns out that it works fine but with some exceptions. The clearance between the prop hub nuts and the front of the engine is too tight to insert the tool with the friction grommets in place. I removed the grommets and could slide the aluminum gauge in the gap and over the nuts. There was some minor side-to-side slippage, so I used some double sided foam tape to secure the gauge exactly when the #1 cylinder was at TDC to align the TDC mark on the gauge . Without the play, the 20deg notch was solid and good for timing the IO360KB engine. Happy with this

Great tool, everyone with a continental should have one. Most A&P and IA have one

Great tool. Works as advertised. So easy, just set engine near tdc and slide gage over prop hub bolts. One negative, on Bonanzas where cowl does not remove, they should print timing marks on both sides of gage for siting down the case centerline. I had to duplicate marks on other side of gage. Still not a big deal. So much easier than timing with a cone. no leveling, no spinning prop.

This is a great tool if you want to do a quick check on your magneto timing for the recommended engines.
