[@ticoman6007]

dude, you material its great for aircraft mechanics, i use it here in mexico, tahnks for you time.

[@akcylinders]

Awesome glad you are enjoying it!! Thanks for the comment 👍🏻

[@pusherpilot]

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 ?

[@SkidzFPV]

I do this everyday

[@Ryanbaggarly]

What do yall get paid to do that in Alaska?

[@wilterdude_1421]

Why don't you use the ratchet on the micrometer?

[@EatPezzzz]

I have a crankshaft with .0025 runout on the flange. Is there a shop that can bring it back into spec?

[@Tyler-ru6bp]

That is already within spec. If you have a Lycoming crankshaft the maximum allowable runout is .005”

[@EatPezzzz]

@@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?

[@Ryanbaggarly]

Hopefully you check both sides

[@tucaphardm6908]

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.

[@crazy10seven]

Lycoming repair manuals and specification sheets are on their website

[@Ryanbaggarly]

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

[@aaronbartels2930]

This is the "hold your breath" part for the owner... a couple thousandths could cost you thousands $$$

[@maximolopezsr9399]

Question do you have a Granite table to start all this measurements

[@Ryanbaggarly]

No we do it here in Texas on a old ass wood table

[@fdfnfgnjfdjfjfk1436]

I don't see the car mechanics doing this.... That's y the aircraft industry is a serious business...
