2135QTi Max wouldn't break lugnuts

[jrcampbe]

Hey guys,

I have a new IR2135 quiet Ti Max impact wrench. My compressor is an old cast iron two-stage with a crappy limit switch. It cuts out at 125 psi and restarts at 75 psi. I plan to fix this when the weather is better. I removed the regulator and run it wide open into the impact wrench through 50 feet of flexzilla 3/8 hose and the nice Prevost euro style couplers.

This weekend this setup would not break lugnuts on my F-150. To be precise, it broke two after lots of hammering and I gave up and used a 30" breaker bar. I live in MN and there was lots of corrosion. After removing the lugs, I had to beat the wheels off with a sledge using a 2x4 as a drift. I also had to pound off the rotors. I greased everything going back together so it will be easier next time.

My question is: does this seem reasonable? Supposedly the 2135 is meant to do 780 ft lbs loosening. I'm a big, strong dude (300 lbs) and had to really grunt to get the bastards off with the breaker bar, so I suppose it's possible they needed more than 800 ft lbs., but that seems pretty far fetched to me.

The thrust bevels on the lug nuts are pitted and nasty from galvanic corrosion.

So, is the impact wrench ok? Or should it have removed these?

Thoughts?

Jim

Well the answer beats me, but I will say if there was that much rust an corrosion, I'd hate to have to work on that thing too often.

You either have a defective impact or you don't really have enough air (90-100 psi and at least a 3/8" line) .. The IR 2135tiax kick **** on everything I've used it on.

 

[devoncoolman]

Chances are those bastards took alot of force to break loose. Your gun is probably ok.

 

[G1GRANDEUR]

do you have air regulator gauge installed on the line?

sometimes my 1/2 snap-on impact gun could not get some of the lug nuts on big truck (dodge heavy duty).

I suspected not enough air, actually. Air tools are a new upgrade to my garage. Looks like a compressor upgrade may be in my future...

I would guess its the compressor. Mine breaks lug studs if they are that frozen (ie cross threaded)

No, I removed the regulator. The compressor is very old, with a 30 gallon tank. It does puff its way up to 125 psi though.

No way mine is putting out enough torque to break studs.

 

[shockwave]

Check air valve inside handle I have had them faulty causing gun not to put out torque

And is there any rust on lugs I gave had them affect taking bolts off before

 

[bikeguy5]

could you have some kind of restriction in the line? possibly ice. I'm just guessing.

What about CFM? PSI is one thing but, the TI impacts need 4-5 cfm to work well. that impact should be breaking studs, not balking at loosening anything.

PSI and CFM are directly related, and I doubt 4-5 CFM would even turn the tool under no load.

125 PSI through a 50' 3/8" hose should be fine for that impact. bikeguy5's suggestion of ice or another restriction is definitely something to check out.

Use anti-sieze on lug nuts and the wheel hub so it is easier to get apart next time.

I've had the same issue - sometimes a breaker bar is the best way, plus you have a better idea of what is about to happen (ie you can feel the bolt failing and about ready to twist off).

 

[meier motor sports]

id try it again on another truck. if you get the same results, bring the gun back

At a starting pressure of 135 PSI using a 50 ft 3/8" hose with good fittings, the pressure at the inlet of the 2135 will be just over 90 while free speeding. So if you are starting off at 125 PSI and dropping from there, I suspect you are starting in the low 80's and then dropping as you impact. With your current setup if you change to a 25ft hose you will gain a few psi at the inlet but probably not enough. Best bet is to get the compressor shut off set higher and try it again. If you still have issues, PM me and I will help you out.

I wouldn't crank up the pressure on an ancient compressor as described by the o/p without pressure testing the tank. But I would imagine that's the issue here, he's probably only seeing 125psi for a few seconds, not enough to break things loose. Antiseize isn't a good idea on the tapered seats of lugnuts, if there is corrosion there, replace the nuts.

No need to pound off the wheels. Just loosen up the lug nuts a little, drive it a little while making turns and the wheel will be loose enough to take off.
