First of all I'd like to congratulate the Chinese scooter Mfgs for figuring out how to train gorillas to put on variator and clutch nuts. That said, I am not a gorilla and my 1/2" impact wrench cannot get some of these insanely tight nuts off, so I'm asking you all what you use. On my first scooter, "Scootie", I had to grind the clutch nut off after three impact wrenches, mine, a mechanic friend's, and the local scooter shop's, all failed to remove it. Then I had a 250cc nut I couldn't get off, and now a 50cc nut I can't get loose, so I'm going to buy something with more buttocks. Here's what's at Harbor Freight: www.harborfreight.com/12-volt-1-2-half-inch-emergency-impact-wrench-92349.htmlThis is the Pittsburgh 12v Emergency Impact Wrench. I had some bad reviews, with many complaints about not getting nuts loose. It is rated at 150 ft/lbs, got 2-1/2 stars out of five, and it's only $22.99  www.harborfreight.com/12-in-Professional-Air-Impact-Wrench-68424.htmlNext we have the 1/2" Central Pneumatic "Earth Quake" Professional Impact Wrench. It had several bad reviews about breaking down and not having the torque specified. One review said their cheap electric worked better. Some reviews said it was good but several said not for rusted on nuts or that it was good for light to medium duty. It is rated at 700 ft/lbs, got 4-1/2 stars, and is $99.99 ~ only $74.99 with coupon.  www.harborfreight.com/3-4-quarter-inch-heavy-duty-impact-wrench-66984.htmlLast we have the Central Pneumatic 3/4" Heavy Duty Impact Wrench. The reviews for this one were very favorable, even for getting big nuts off of cranks and pulleys and even Mac Truck nuts. "Like butter" said one reviewer. It is rated at 1,000 ft/lbs, got 4-1/2 stars and it is $94.99  I really hate returning things to the store so this last one seems like the most sure bet without spending a lot or going to a one inch impact. It also looks like it will work well on cars, but before I buy one tomorrow, I'd like to hear everyone's input on what has worked for getting these gorilla torqued scooter nuts off, especially ones torqued from the factory. |

All I can tell you is what I have experienced. I have the 12v emergency impact wrench, and I've never had an issue with removing any of the nuts on my scooter with it. I can change variator weights or the drive belt on the side of the road in 5 minutes flat, and have used it to change tires on my neighbor's Ford Explorer as well. It is a wind-up-then-whack type of impact wrench, and it has never failed to remove the nut within 2-3 whacks, I also install the variator nut only allowing it to do 2-3 whacks. Best $20 I've spent on tools in a long time!

i had same issue with my first impact wrench. took it back and got a cordless 330 ft/lb that did the job. it was a bit expensive at $120 but well worth it imo.  www.harborfreight.com/18-volt-12-in-cordless-variable-speed-impact-wrench-60380.htmlone trick i picked up from a YT vid... if it won't budge, click the reverse and tighten the nut with a quick 1 or 2 second blast. then reverse and try to loosen. i had to use that method to remove my rear tire recently. |

If you have a compressor, that 1/2 inch 68424 is the bomb! I have one that I purchased to work on cars. It has 4.5/5 stars with 272 reviews for a reason.... it works well.
You would not believe some of the work I have done with one. I have had a few cheapies, but this one is worth keeping. Be sure, as with ALL air tools, to lube it before use.

Having both a Milwaukee impact wrench (120 volt) and the Harbor Freight model, The latter is great at removing stubborn nuts without putting undo strain upon the bolts and snapping them. (I was really surprised at how well the H-F model worked.) Hope this helps!  |

Best $20 I've spent on tools in a long time! I also have the same impact wrench. The issue most people seem to have with it is that they cannot remove factory or air driven tightened nuts. I also have a huge 50 gallon tank and an impact wrench that used to be used by my mom's friend to repair air planes, so it's got probably the same kick if not more than the factory ones. If you have trouble with the electric emergency wrench it may be a sign that the nuts have been overtightened. The electric emergency wrench is perfect for getting the bolts and nuts for a scooter on and off, nothing on a scooter has a torque rating higher than the wrench. That said, the first time I loosened any of my bolts or nuts they were impossible to remove without the air driven wrench. I however did not have the electric wrench until recently. How does it work on the factory tightened bolts and nuts? Give you some trouble? All of my bolts and nuts have been re-torquedto correct or close to the correct specs I got from the generic gy6 50cc manual, so I haven't had any issues, but I had the air driven wrench when I did all that. |

I use it to remove the variator pretty often, including the first time. Never had any problems. When I put the variator on, I let it whack it three times, no problems coming loose or removing with two to three whacks later.

If you can't remove any nut on a scooter that you want to, with a 1/2" drive impact......then you better adjust the inline pressure regulator. If you are getting  psi to your wrench, it will work on anything that some dope didn't apply Red Loctite to. I use a Craftsman 1/2", but never at the highest of it's 3 torque settings, but rather at the middle setting. Even then I won't let it hammer on a nut when tightening, just a couple of raps past snug. I do have both a 3/4", and a 1" drive impact too, left overs from my truckin days. Way too heavy duty for anything but 18 wheelers, ag tractors, construction equipment, etc. |

I'll be in the South Bend area today, and most likely picking up the emergency impact from harbor freight. The emergency impact I had magically disappeared after 6 1/2 years-- picked that up at wallyworld, and they don't have it anymore.

I have an air impact wrench that I never use. One of these days I should since I know it would make removing the variator, clutch & rear axle nuts quicker and much easier. BUT! I would not use it to tighten those nuts. I do have torque wrenches and use them. Doing repairs while out on the road could be complicated by not being able to remove an accidentally over tightened nut. And I have replaced a drive belt on one of my Reflex scooters while on a trip for camping in the Catskill Mountains of NY that required the removal of both the variator and clutch. (needed to make sure all the shredded bits were removed) I have always been able to remove nuts that were properly torqued with the wrenches/ratchets/sockets that I brought with me. No such guarantee if a nut were overtightened. I make several long distance rides on my scooters, so I try to make sure I can do repairs myself at the side of the road. That may not be as critical for those riding within easy retrieval distance of home. So whacking it off or thumping it on with an impact wrench might be OK for them. But I don't think I'll risk thread stripping, snapping bolts or being unable to loosen something while traveling..... But that's just me.  |

The 18v ones are so nice but I cant afford that price,,,I have an old electric 120v 200ft lbs one from Lowes,,it works great for doing everything from mower blades to wheel lugs,,never a task too hard,,only problem is you are limited by the size and the cord or voltage supply...

That's the whole point of the " 12v 1/2in Emergency Impact Wrench", I store it under my seat and have a cigarette lighter power adaptor so I can change a belt on the side of the road in less than 5 minutes flat! |

After using a 20% off coupon, the 12v emergency impact from HF was only $19.68. Good deal.

psi to your wrench, it will work on anything that some dope didn't apply Red Loctite to.
