I'm always amazed that they can make them for 10 to 30 bucks for the non USA brands. I've had a central pneumatic sander for about 10 years now. Cost me like 20 bucks. Built like a tank and works great still. Yet I just paid 80 bucks for an Ingersoll Rand 2 inch die grinder, just to find its still made elsewhere. Yet they almost look identical in build quality. That little switch valve is the secret. I've seen them leak brand new. Others after 10 years don't leak. Crazy. Thanks for the video 👍
This is a great breakdown! It'd be cool to see a comparison with a disposable version like the Harbor Freight Central Pneumatic. Did/would you put loctite back in that big collar's threads when putting it back together to use? I recently picked up a handful of old used Japanese and USA die grinders, they're great but some of them a little leak air around the head. I wonder if a thread sealant there is standard from the factory for high quality ones, and it doesn't tend to get replaced when users or ebay flippers service it?
Sounds like someone put the vane shaft in backwards. The transfer case gear can't be reversed. So it can only be the drive vanes . It's air that causes it to rotate that's all. It's like turning windmill blades the opposite way.
How did you get the threaded part loose that holds the big assembly in the handle? I need to replace the bearings in there but that's keeping me from it. Though there might be a trick?
All I used was a big adjustable wrench and I held the body in a vice wrapped with some rags to protect the aluminum. Applying some light heat may help to break the threads loose as I believe they come with some thread sealant to keep the air from creating a spiral leakage path from the rotor chamber.
Internal parts worn probably from lack oiling resulting in the clearance tolerances are worn to the point it can't produce enough pressure to supply to torque it should have.

Cool video
Is there a way to make an air tool run backwards
Dose Mac make their own air tools like this and air saw?
I think they are rebranded Japan made. I know the flex head one is made by SP tools Japan but not sure about the entire range.
Any idea what would cause my AG60AH to rotate in the wrong direction?

Kick where did you get the parts?
резьба левая или правая?????????????
Sir motor works but does not take load,
What is the reason?
Internal parts worn probably from lack oiling resulting in the clearance tolerances are worn to the point it can't produce enough pressure to supply to torque it should have.
@sullie35 can they be replaced and take load again and not bog down?
What size is that woodruff key?
I believe it was a No. 1 key. May have been a No. 2 but I'm pretty confident it was a No. 1. It's a super tiny key.
