Help removing crank pulley.

[Periokid]

I am trying to remove the crank pulley for my supercharger install.

It will not budge no matter how hard I try. High torque impact guns will not work. I have a breaker bar but i can't keep the engine from spinning.

i understand there is a tool that keeps the engine from moving.

Can anyone help me here?

You need the NSX / TL tool as you stated. I had to have this for the timing belt too.

I had to call and beg the dealer to loan it to me.

good luck

My dealer refuses to loan me the tool.

The "tool" is basically a big breaker bar with the right sized "nut" holder / socket on the end.

I would have thought an impact wrench, if anything, would have done it.

I think your best bet is to try another dealer or have CompTech FexEx you one.

There are a couple of ways to beat this one.

(a) 3/4" drive impact wrench will unzip the nut, so with enough grunt, high-impact air guns do work.

(b) if you have a helper, remove the flywheel inspection cover via three 10mm bolts, have him jam a large screwdriver or a small prybar into the flywheel teeth and with cheater pipe you can break the bolt loose. BTDT.

GMSC, right?

Thanks for the info guys!

It is a comptech unit circa 1998-1999.

Questions on the above:

I can find a 3/4" impact wrench, but I can't find a 19 MM socket to fit it. Any ideas where to get it?

Using method B, will I risk damaging the crankshaft?

Got it yet? As Andy said, an impact should work but it takes a beefy one. They come in a very wide range of efficiency though and a cheap one won't produce a fraction of the torque you get from a good one. A real strong 1/2 inch with enough air to run it should do the job. A 3/4, especially a cheap one, will require much more CFM so you need a pretty big compressor tank.

I didn’t do it that way. I made my own tool by finding a very large hex nut about the size of the hex shaped recess in the front of the pulley. The closest I could find was a bit large so I had to cut it down somewhat on a grinder. A bit of work, but not real bad. Anyway, you can then insert the nut half way into the crank pulley and use a giant crescent or pipe wrench to hold it, with the wrench levered against the frame or floor. That holds the crank so you can use a socket and breaker bar on the bolt. I didn't have room to use a pipe for extra leverage so I needed to use my leg to get enough on it. Not elegant, but it worked.

No, the crank will be fine. Many cars are done this way with special tools that do the same thing. The only real risk is to the teeth on the flywheel and that would be very unusual. I guess the person working the cheater bar is at some risk if the screwdriver/pry bar slips off suddenly.!

Look for a "Mac Tool" truck sitting on the side of the road servicing a local shop. Or ask a local shop when he stops by. Ask the Mac guy for a Honda/Acura crank pulley removal tool. Costs $35, it attaches to your breaker bar, and will insert into the pulley and hold it while you use another breaker bar and socket to insert thru the middle of it. It has never failed for me, and is worth 10x the price with as much frustration it has saved me.

If you do not have a Mac Tool truck servicing your area, try ordering it from Moroso, they sell one with a long breaker bar handle already attached to it, but i think it was in the $80 dollar neighborhood.

Nothing beats having the correct tools to do the job. Invest a little money in them.

Agreed! And $35 bucks is very reasonable. As long as you aren't in a big hurry and need it during a holiday weekend (but don't you always?

) it beats heck out of my DIY tool method.

Thanks for all the great feedback.

I'll try to obtain the tool. I never dealt with companies like snap on or Mac Tools.

Mac Tools' online store is currently inactive, figures.

You can't imagine how this is driving me crazy.

I have completed just about every single step of the supercharger install. All that is left is the belt. Everything was so smooth until this damn pulley!

I just had the timing belt changed by the dealer and they must have one strong mechanic! Of course they refused to help me out unless i brought them the car. No tools for loan from the Acura dealer!

What a bunch of a-holes IMO. My dealer KNEW I was doing my own timing belt and still loaned it to me (I was drinking fruity drinks and talking while Barn Man did it - actually).

Which brings up another point. You'll need a pretty hefty torque wrench and room for a smooth pull to put it back on at 181 lb-ft.

Ordered the romoval tool.

I hope it is the correct item.

Mac Tools had only one item that fit the description. Part # HDH6010

Hardly the bargain I had hoped it would be.

The item was $63 and since it need it by the weekend, it was $20 to ship. Plus tax

I hope it is the right tool!
