An impact gun will remove the bolt without spinning engine then I believe a puller is needed to remove the balancer.

It has to be a damper puller.
Not one of those that grabs the outside only. It will come apart with the wrong puller.

Yes, a pneumatic wrench will do the trick quite nicely. Lacking that, Sears
sells strap wrenches that have a seat belt like material combined with a
tightener and a long handle. Wrap the belt around the harmonic balancer
perimeter, tighten it up, brace the handle, and pry away.

This will do the job to get it off.....

You will still need a Balancer installer ( can rent them for free from O-Riley"s ) to put it back on properly without damaging your new front seal.

I think someone has already mentioned that you need an impact wrench. That will zip the bolt out for you. Then, you may need a puller. I did not need one to remove mine.

my 1st choice would be an impact. If you don't have one you might try a couple of sharp raps on the breaker bar with a heavy hammer. Or you could gain access to the flywheel starter teeth and wedge it and try to loosen the bolt.

You could make a home made tool like this to get it off:

I made a similar one when I did mine and it worked well.

I'll bet this $50 impact wrench would do the trick, and it's a good tool to have around.

Interesting item, but I think I'm really wanting a battery
powered impact wrench, not a 120V AC version.

H.F. has a couple; 1/4" Drillmaster on sale for ~ $20 and
1/2" Chicago Electric on sale for ~ $115. The 1/4 incher
states 850 inch/pounds which I assume translates to a bit
over 70 foot/pounds. Is that likely to be enough for wheel
removal? I sort of doubt it since I seem to recall having
seen a statement on this list that torque as high as 250
foot/pounds is tightening specification for wheels.

It would appear that this one with 205/211 foot/pounds of
torque would be more likely to serve the purpose.

(http://www.harborfreight.com/power-tools/drivers/18-volt-12-cordless-impact-wrench-67845.html)

Yeah, I know. I have read many of the derisive comments
regarding Harbor Freight tools, but I wonder if any of you
have had any PERSONAL experience with their battery powered
impact drivers.

Be careful about buying battery powered impact tools. I suspect it is another of those "you get what you paid for". I have a $250 battery powered impact gun that is suposed to have 1100 inch pounds of torque and has trouble undoing wheel nuts tightened to 90 ft/lbs. It usually will do the first wheel, 5 nuts, and then starts to get week, I have seen an expensive Snap On gun undoing the center lock wheel nuts on a Porsche GT3 Race car and I suspect these nuts are over 250 lbs. Cheap( how much is cheap??) battery powered impact tools are good for spinning off loosened up nuts and spinning them back on but it takes some money to break loose the wheel nuts on a Motorhome.

Mac,

I have one of these here in Sydney:

http://www.harborfreight.com/catalog/product/view/id/2420/category/1352/

It is not worth $25!

I have one of these in Humble, TX:

http://www.harborfreight.com/power-tools/drivers/12-electric-impact-wrench-68099.html

It IS worth $49.99 - I spotted them on sale for $39.99 and bought one for me and one for John Sharpe.

Ken H. has had one for some time and he's happy with it.

It appears that the 18VDC model has the same case as the 120VAC model; however, I can't provide any personal experience with it.

I do have one of these drills:

http://www.harborfreight.com/192-volt-1-2-half-inch-drill-driver-kit-96526.html

It is the second one I had, the first died after about a year. I bought them on sale for $19.99. The batteries last about as long.
Keep in mind that I only return to the USA for 3-4 months a year and the batteries sit for long periods of time.

Regards,
Rob M.

Brian,

Roy's plan will work best, but the starter has to be removed. No big deal if you disconnect the battery first.
Carl's is also a good plan - if you have an adequate hunk of steel handy.
Roy's sometimes takes two people and Carl's has to have room to work - your call.
I have done both, but as I was usually working on a stand, jamming the ring gear teeth was easiest.

I have the battery powered 3/8" impact from Harbor Freight that I use all the time on smaller stuck bolts like exhaust manifold bolts. etc. I love it as long as you realize it's limitations. We also have a 3/8' drive battery powered Milwaukee. It does nto do any batter than the HF one.

We have an 18 volt 1/2" battery powered Dewalt impact for heavier things but it barely can loosen a 100 ft.- pound automotive lug nut. After 100 ft.-pound we resort to air driven impacts.

i did manage to break a bolt of in the harmonic balancer trying flat bar idea. . shopping for inpact wrench now. i do not want to remove starter and end up with flywheel problems .
one mechanic i spoke with today suggested breaker bar on nut and bumping starter, has anyone tried this?
i thought i was going to do this and maybe save a couple dollars, i am starting to think i should have taken time off from work and driven to florida for a couple days. quote from sirum is starting to look god, but i can see cover,
related
oreilys gave me 2 quotes today on water pump, 50 dollars for 2 yer warranty one and 25 for a lifetime one. the lifetime one looked similar , approx 1/4 inch shorter, and the impellor was round not like mine with the blades. mine has not failed, but since it is off,
input appreciated on water pump also,
thanks bgk

Go to NAPA and get:
NAPA 130-1260 (old #)
NAPA 43-100

Measure the impeller BEFORE you leave the store. The one you want measures 4.25 inches. NAPA had some of their inventory screwed up in the past and smaller impeller pumps got mixed int he the larger ones. The last one I bought was just under $40.00 with a lifetime warranty. Each NAPA store sets its own prices but it should be in the neighborhood of $40.00.

I would suggest a good air powered impact (2 stage) a cheap air impact or an electric impact may not have enough torque to break that big bolt loose. I have a nice Milwaukee electric and a cheap air impact but they don't have close to the torque of my 2 stage air impact. Good luck & with the right tools or technique it isn't difficult.

OK - I'll bite. What is a "2 stage" air impact wrench?

What brand, which model number?

Wrong wording it should read double hammer. At any rate some of those cheap impacts wouldn't loosen the bolts on a full size cars wheel lug nuts much less a 1 1/8" bolt (head size)Don't quote me but that is the size I think it is from memory.
