Lycoming Crankshaft Dimensional Inspection

- In this video we show you how we take a cleaned crankshaft and start the inspection process. It's all about measuring and making sure that everything straight.
First we use a dial indicator to check the propeller flange runout to make sure it isn't bent. Then check the intermediate and rear main journals for runout. Finally, we use a micrometer to measure the main bearing journals and crankpin journals to determine whether or not they are within the manufacturers serviceable limits.

We hope you enjoy our videos, thanks for watching!

dude, you material its great for aircraft mechanics, i use it here in mexico, tahnks for you time.
Awesome glad you are enjoying it!! Thanks for the comment 👍🏻
Nice. Do a video on how and what parts you send off for magnetic particle and dye testing after a prop strike. (Case, crankshaft, etc. and how you send it to the inspectors. Just a recommendation. Great job. Subscribed.
When the Propeller pull, where are the thrust bearing locate ?
What do yall get paid to do that in Alaska?
Question do you have a Granite table to start all this measurements
No we do it here in Texas on a old ass wood table
Hello. Help me please. I disassembled the entire lycoming io-360 engine. ordered pistons, cylinders. But I don't understand what's wrong with my crankshaft. Where can I find the dimensions, passport for crankshaft repair? Need troubleshooting. I live in a remote area.
Lycoming repair manuals and specification sheets are on their website
Start by micing it to see if it's under spec. You are only aloud so much for your taper from exhaust to intake. You runout could be off
I have a crankshaft with .0025 runout on the flange. Is there a shop that can bring it back into spec?
That is already within spec. If you have a Lycoming crankshaft the maximum allowable runout is .005”
@@Tyler-ru6bp thanks for the reply. I'll be using an 8" prop extension. I'm assuming that the runout would be exaggerated at the prop. Is this something I should be concerned about?
Hopefully you check both sides
This is the "hold your breath" part for the owner... a couple thousandths could cost you thousands $$$
I don't see the car mechanics doing this.... That's y the aircraft industry is a serious business...
