There was a product out and no longer available anymore after 9/11/2001.you poured the stuff in and let it soak overnight,this stuff worked.

Sorry, i know this was written a few months ago, but seriously, what was the point of even taking the time to type that? You just told someone that there is a product that no longer exists that would fix their problem..haha

 

[Shadowdog500]

Out of curiosity what was that product?

Take your vanes out and clean them up. From your posts it really sounds like your vanes were stuck. From what you said it sounds like one or two vanes are working but the rest are stuck. That would explain the working but not having power. I would take it all apart and clean everything up good, lube and grease good and put back together and then enjoy your new impact.

While you are have the vanes out, give the bore they ride in a good inspection. If the edges of the vanes have burnished the bore or left burn deposits on the bore-- a sign of the impact being run without proper lubrication-- be sure to clean up the bore. I found that a Scotchpad followed by 600-grit wet-dry lubed with oil works well.

I also touch up the edges of the vanes that run in the bore with a once-over with oiled 600-grit wet-dry, being sure to maintain the convex edge shape.

Also, be sure to clean out the vane groves in the impeller. The vanes need to move snugly, but freely since centrifugal force causes them to seal to the bore walls on spin-up.

One final tip: It's almost impossible to over oil an impact tool.

ATF? Would that not damage any type of rubber seals? (trigger, ect)

Pic shows my 2135Ti and 2115Ti

I purchased a grease gun from NAPA (Ultra Pro # 79047) which came packed with grease for around $5.

You will notice that the grease fitting on the Titanium guns is beneath the anvil

I greased them both with full grease gun (Ultra Pro # 79047) I picked up at Napa for around $5.

yes, atf in all my air tools with no problems.

Your hammers are installed correctly. The problem does not sound like vanes, as the tool is running fine at free speed. There does seem to be a lot of wear on the front diameter of the anvil where it passes through the Hammer case busing, beyond what is normal. Make sure the Hammer case bushing is pressed in all the way, clean up any galling on the anvil shaft and grease shaft well before re-assembling.

How in the world do i remove the End plate to access the vanes?

Ive tried pulling at it with my hands, taking pliers to it, tapping it... doesnt move!

The hammer case bushing is indeed pressed in all the way, it is flush on the front face side of the gun.

The entire gray piece of plastic comes off in 1 piece. The vanes are under it. It just pulls off, although it might be snug because its a new gun

 

[tonydanzah]

its not plastic on my gun?

 

[KenS]

Looks like the rotor shaft is being held with a snap ring-- No. 7 in this drawing. Have you tried removing it?

 

[tonydanzah]

that snap ring is on the back side. I bet if he just tapped it on a table it would come free.

Pull out the air inlet. You can see the release tabs in the pic of the handle in post #37. It will slide out as an assembly. There is a small snap ring on the end once removed. Disassemble it & get a good look at the star wheel & the cup ends that are there. The cups tend to crack & cause the same symptoms that you have. I have fixed several of them.

 

[fr0mastaj]

Bah, so its not the vanes...they move freely in the housing, none of them are stuck at all... I am about to give up! Everything looks dandy

Will try to take a look at the air inlet next. Dont have a wrench handy at the moment...

It's actually hard anodized aluminum.

You need to check not only the vanes, but also the bore they run in. The bore should be clean metal similar to a freshly honed engine block cylinder bore. Make sure there is no burnished brown deposit or residue left from the vanes deposited on the surface of the bore. Give the walls of the bore a once over with some oil-soaked 600-grit wet-dry sandpaper.

Also, check the cups as per daveblank's post. If everything looks okay, reassemble it-- flll it with a good air tool oil (I actually fill my bore with oil before assembly) and see if it is freed up.

 

[Marlin]

I'd be careful of using any sandpaper on the bore of this cylinder, it is plated aluminum and you don't want to damage it. The impact is new and there really should not be any build up in the motor. DaveBlank's recommendation is good, check the tilt valve in the inlet. You can remove the inlet using two thin blade screw drivers, make sure you remove the trigger before inserting the inlet back in the tool then snap the trigger in.

Im interesting now if you get this thing running nuts.

Marlin,

I agree with everything you have said, but what I have found is that "new" units like this have sometimes been put into service without being oiled and the bore becomes coated with residue from either the vanes or from the overheated factory oil. Looking at his photos, everything looks relatively pristine, and without having the unit in my hands it's difficult to troubleshoot.
