Timing belt job/removing crank pulley with cheap impact

[jblackburn]

Even removed the axle nuts on a 95 850

That alone is impressive!

Of course you need an air compressor. If you don't have one you could always make an excuse to go buy one .

What are the specs of your compressor? I have a Husky that's rated 2.8 SCFM at 90 PSI . I'm using a Palm Nailer with it while I finish my basement(I have arthritis so swinging a hammer is not an option!). I'm guessing my compressor is not up to the task of driving a 1/2 " impact gun? What do guys think?

I have a CV replacement on my 855 coming up so anything to make that easier would be great.

Having an impact gun vs not having an impact gun is night and day - cheap or not. That having been said, buy an IR titanium and call it a day for the rest of your life. Blows away virtually everything out there including Snap on. But they are not cheap.

I have one of those in my house right now. All boxed up ready to go back to the vendor I bought it from. For the $$ I was NOT impressed. I bought a 2135qtimax.

My $30 Kobalt was just as good believe it or not. There must be something wrong with it, only thing I can figure. $270 vs. $30?

The key to a consumer grade compressor driving an impact gun is storage. CFM doesn't matter, as pretty much any 1/2" impact will pull ~25 CFM at load. The ratings you see are average 25% duty cycle ratings of 5-6 CFM.

To drive a 1/2" impact I would look for a compressor that was at LEAST 20 gallon, 150 PSI or more. Your compressor might run an impact but not for long enough to get any benefit out of taking off the axle nuts.

I have a 3 gallon compressor I can throw in my trunk and a $24 Sears impact wrench. I've used them to take off axle nuts, swap and separate a complete engine and transmission, swap a 240 axle, and rebuild suspension on 4 cars so far. I run the impact wrench at the recommended 90psi. The 3 gallon compressor is more than enough air for any project you're likely to take on at home.

Almost everybody in the shop I work in uses them and you can break loose pretty much everything. Maybe yours' needs to break in? I've noticed impact guns being kinda tight when new.

If you are having problems getting the bolt to break loose, Use your hand around the socket and slide it in the reverse dirrection. you will hear the socket hit harder. If this doesn't woork youi need a better gun, more air or a long breaker bar.

not sure if this is the right thread, Don't mean to hi jack it, I need to get going on this timing belt. 1999 S70 Turbo.
1. I couldn't get the 850 manual to down load
2. does anyone have any recommendations on belt kits or should I buy OEM
4. Does every one change the oil seals, the pump is a given
5. I asked this before, looks like I have what i think was called variable cam timing , but it is on the rear pulley, all mention as been that it would be on the front.
6. All notes how important is not to let the cams move at all and that you make t tool to hold the two cams. Yet if I pull the two cam pulleys I have to remove the tool.
7. Can’t see bending a valve by letting the cams move, as long as they are lined up properly in assembly.

Any help would be appreciated, I have to get this thing running, My wife if driving my surburban and I and trying to get around in my 67 mustang, it will be broken next.

cknapp58,
You're probably better off starting a new thread. You may not get much attention deep in this impact wrench discussion. You probably want to get Ozark Lee's input - He did the "major maintenance" thread above that has the timing belt documentation.
