2235timax losing power

[Sugarfryz]

I use my 2235timax daily at work, doing auto repair. I use my 2235ti and my Milwaukee fuel about 50/50. Lately my 2235timax goes through spurts of losing power. Today it couldn't even tighten lug nuts to 100 ft lbs (with a torque stick), then was fine the next with that same torque stick, then the next hour ripped out a rusted Honda crank bolt like it was nothing. I beat the **** out of this gun, it's oiled daily. I do grease the hammers. My only idea is I did overgrease it recently. Some worked its way out of the tool, which can make me think it's causing the power loss but what's confusing me is it's somewhat intermittent.

My only real idea is maybe it's a combination of the over greasing, and air supply issue, but my other tools seem to run fine.

The guns running on 2 years old, is there anything I could do to just attempt to liven it up a bit, maybe clean it up. I feel if I take it apart to clean it up I might as well buy a tune up kit

Any ideas would be appreciated

Betcha a ten dollar bill some of that grease has worked its way into the air motor where it doesn't belong. Grease gobs up the air vanes and slows down the RPM's

Don't buy any parts. Take the 4 main retention screws out and separate the two halves. Clean out all but a little grease from the hammer case then clean up the air motor's vanes and cylinder. Re oil and assemble minding the ordination of the air vanes. Simple clean up wakes up most composite Ingersoll impacts.

If you use it day in and day out i'd get the kit if for no other reason than to refresh the motor bearings and vanes.

You can over grease and over oil them. It takes a lot of grease to get it to the point where it would start packing the motor passages though. One of those little tubes should last you years. More common is too much oil then the vanes get sticky or the motor bearings get worn out and the rotor starts wearing into the end plates.

Maybe too much oil. There was a point that where I put in 10 drops a day twice because on the it air tool oil they gave me with my grease kit said to do so. I don't use near as much tho. I've noticed lately after I oil it, no oil will come out of the exhaust like normal.

How much grease is just a little? I definitely over greased it, but too little seems worse. I also have never taken a gun apart, would it be worth it to just give it to a tool guy to send out so I know it's right? I'm sure I can figure out but I don't have the time at work to mess with it, I'm trying to make money.

I've "flushed" one or two gunked up impacts with penetrating oil before...seemed to help? I'm sure disassembly/cleaning/refreshing would be best.

You're a mechanic, you take apart broke **** and fix it for a living. This is no different. Just remove the 4 long screws that hold the nose cone to the body and carefully slide the two halfs apart being carefull to not lose the housing gasket or thrust washer. Dump the hammer and anvil assembly out of the nose cone and wipe out all the grease. Put a half a teaspoon of the correct grease in the nose cone and replace the hammer/anvil assembles, the grease will distribute itself during use. Remove the front air motor bearing and end plate assembly and pull all the plastic looking vanes out noting their orientation in the cylinder. Clean the vanes in mild solvent (WD-40 on a rag is fine) and clean the rotor and cylinder if there's grease or buildup. Lightly oil the parts and reassemble. You can do this on you're lunch break. It's really pretty easy.

Unless you make enough money to light it on fire you can do it yourself in a half hour on a weekend. IR charges something like $150. I took mine apart for giggles a couple weeks ago. Probably one of the simplest impact wrench designs available. I've had basic hand ratchets give me more frustration.

i have an ir2130 that had the exact same issues as yours. i took it apart and cleaned everything with brake cleaner. after reassembly i added 4 drops of marvel mystery air tool oil and greased the front end....works like a charm.

 

[Sugarfryz]

Thanks guys. I'll go ahead and take it apart today, redwrench you have a damn good point lol. I'll let you all know how it goes

Year back in the bodyshop we had similar issues with air tools. Old shop owner showed me a trick. He ran about a tablespoon of lacquer thinner through it about 5 or 6 times. Then 2 drops of Marvel Mystery oil.
Thinner cleaned out all the gunk. Just do it far away from anything you don't want greasy, nasty thinner getting on.

Take off the hammer cover and remove that grease. Too much slows them down. Pop the end off the motor and look in there, if it's not gummed up,put it back together and let 'er rip. Either that or you've got air loss somewhere. Check it out the back when you pull the trigger,around the power adjust and especially out the direction buttons,also the slits in the handle where the clips reside that hold the inlet valve in.

Took it apart and took extra grease out. Cleaned it all up. Works like new. Was pretty easy too

When you grease the front end in the future just go easy.. the whole point of grease is that it stays where you put it- you need very little for the grease to do its job. Most people putting grease in anything put in way too much. Next time you get a new air tool, take it apart and look at how much grease it comes with- you'll probably be surprised at how little grease is in there. It's not a mistake.

 

[Sugarfryz]

I'll keep that in mind. For future reference how do I know when it actually needs grease? I asked more experienced techs and they said they never grease it. But they've had them rebuilt af least 3 times.

Grease life in your tools is going to depend a lot on you environment- temperatures, humidity, dust levels, etc. Also, of course, how much you use your tools and how hard.

Id start by just taking the nose off once a month or so and checking the grease. Grease that is still good will not separate, won't be full of debris, and should be similar in color to when you put it in new.

When you start to hear the hammers banging around add grease. Add a few pumps and rotate the anvil over by hand until you feel a slight increase in drag.

Hammers and anvil are pretty robust greased or not. Generally rebuilds are necessitated by a lack of oil and increased motor wear.
