If it is of the same type that I've seen then obviously yu need to;
Remove the board or "shoe" the sandpaper attaches to.
Rotate the round gear back and forth that is on the bottom of the sander to get it centered in the stroke.
Replace the "shoe" while centering the flat gear on the back of the shoe with the round gear that was previously centered in its stroke.
If after the sander is put together and the air is applied the shoe only goes one way then disassemble and try again.
If the reason you're having to set the timing is because the rivets sheared that hold the flat gear to the "shoe" then try decreasing the air pressure or it will happen again. Been there, done that.
What else can I help you with?
What air pressure should be used with a dual action sander?
90 psi
How do you oil a craftman dual action sander?
Using a very light oil, pour directly into the air intake (airline connector), 5ml of oil will suffice.
Why is your carburetor blowing air?
If the carb is blowing air OUT instead of sucking air in then you possibly have a bad intake valve. As the piston comes up then the air is forced out the intake valve and back thru the carb. Another possibility is that the timing chain or timing belt is broken and then the piston again is pushing the air out the intake valve. The definitive test would be to run a compression test.
What is The air brake system on tractor trailer?
It's a dual circuit air brake system. Most use S-cam foundation brakes, although some use disc brakes or piston brakes.
What is the difference between inlet valve timing in a diesel engine and a petrol engine?
In diesel engine ,air alone without any fuel is drawn by the falling piston during inlet stroke. In petrol engine, the mixture of air and fuel is drawn in by the falling piston during inlet stroke. There is no difference in the act of actually setting the timing. Inlet valves open slightly before the piston reaches top dead centre, by how much depends on the manufacturers specifications.
What does btdc mean on timing?
BTDC stands for "Before Top Dead Center," referring to the timing of an engine's ignition relative to the position of the piston at the top of its stroke. It indicates the degree measurement before the piston reaches its highest point in the cylinder, where the air-fuel mixture is ignited. Adjusting the timing BTDC can affect engine performance, efficiency, and emissions. Typically, this measurement is crucial for optimizing engine timing in various automotive applications.

How does timing effect an engine to overheat or not?
If the timing is too high on an engine it causes the gas/air mixture to pre-ignite before the piston gets to top-dead-center. All the valves are closed at this time, causing an excessive amount of heat to be stored in the cylinder walls. And the same applies if the timing is too low, but it does it after the piston has passed top-dead-center, and the engine usually runs worse.
How does an air pistol work?
A piston is pushed by a spring, compressing air ahead of the piston. The air blows he BB or pellet out of the barrel.
What is a timing belt and what does it do in a car?
The timing belt is a belt that connects the engines crankshaft to the camshaft. The crankshaft is turned by the engine's pistons and tuns the vehicles drive wheels. The camshaft opens and closes valves that let fuel and air into the engine and allow burned vapors to exhaust. Timing the valves to the piston position is crucial to making the engine run. In most engines the intake valve (allows air and fuel in) is timed to open as the piston is moving downward in it's movement. The intake closes as the piston reaches the bottom of movement and is about to come back up. As the piston rises, it compresses the air and fuel and nanoseconds before it reaches the top of it's travel a spark plug ignites the fuel (if it's a gasoline powered engine). The explosive force of the ignition forces the piston back down, which forces the crankshaft to turn. When the piston reaches the bottom again, another valve opens to allow the burned fuel vapors out of the engine. The piston moves back up to push the gases out. After reaching the top of travel the exhaust valve closes and the intake valve reopens. With out the timing belt, the engine would have no way of correlating the opening of the valves to the placement of the pistons.
What is a piston on a air soft gun?
A piston is the device inside the air chamber that compresses the air that is needed to propel the BB when it is fired. Every time you pull the trigger the piston forced air in the air chamber forward and the air fires the BB down the barrel.
What is the work of a piston?
piston work of the compress air and fuel compression
