Front sprocket removal - help!

Time to change out the chain and sprockets but I'll be damned if I can get the front nut off.

I have an impact gun but it is weak and can be stopped with my hand (you'd think Craftsman would be good). Penetrating oil hasn't helped. Massive cheater bar does nothing. Husband couldn't do it.


What do I try next????

You can try applying some heat with a propane torch. Rhe technique I have found to work best for me is to put the bike on the sidestand and puti it in first gear. Stand on the right side of the bike, put your right foot on the brake and lean over the seat. This will give you plenty of leverage to work the wrench with a cheater bar. You will feel the rear suspension start to compress as you apply torque.

Also, try hitting the wrench with a hammer. Small shocking hits may help free it up

I wouldn't recommend using heat. Man dissimilar metals and a good chance for a fire if your bike isn't squeaky clean in that area.

Impact wrench is still the best bet. Borrow one, buy a new one. Is your's air or electric?
Craftsman doesn't always equal good. Chicago Pneumatic or Makita electric.

Thanks for the suggestions so far.

The impact gun is new and air, so in theory it should work fine.

Caution noted on using heat, but I think that's what I'll try next. I recall it being used before (I've never tried to do this by myself; now I know why )


As for the technique SLO KLR mentioned, that sounds good. But when you consider that I sat on the bike, right foot on the rear brake, while Dan (hubby-o-mine) pulled on the cheater bar to no avail.... I just don't see this happening.

Maybe tomorrow I'll sneak up on it and catch it by surprise!


More suggestions are always welcome!

HAve you got the torque on the impact set to the highest point? Some have adjustment and you may be at the low end. Also what pressure is your compressor at. Best to have over 90#. An air impact uses a lot of air so if you got one of those little pocket size compressors it ain't goin to cut it, or loosen it for that matter.

Good points. I don't recall what I had the compressor up to (and I made sure that we got one big enough to do more than what we ever plan on doing with it, including removing front sprocket nuts!)

Dan and I just discussed the air pressure/wrench settings and will give it another shot tomorrow.


This is sooo much easier when someone else does it

I removed mine with an impact, like KLR4evr mentions above. You need high air pressure and volume to make the most of an impact. I assume you made sure to bend the locking plate back before you tried to remove the nut?

You start with a full bag of luck and an empty bag of experience. Hopefully you fill the bag of experience before you empty the bag of luck.

Yep, confirming that the locking plate was bent back.



I just hope that pumping up the compressor pressure will give the impact the "umf" it needs. It's not the first time this nuts been off!

I had to run my compressor up to 120 psi with my Craftsman 1/2" impact wrench to get the crank bolt off for doing the doo. I'd try putting a 1/2" extension on the center of the nut or the extension and a big socket so you're hitting the nut only, not the bolt center and waking it big time with a 2 - 5 pound sledge a few times. Putting WD40 on it overnight on the backside is also a good idea. Put the bike in gear and hit it hard with the impact wrench and it should come off. I've never had a problem with countershaft sprockets even with a hand impact wrench, but rust never sleeps.

Good Luck,

John

PS: Do you put air gun oil in your wrench EVERY time you use it, it helps it spool up faster and keeps it alive.

Farkled probably WAY too much, but good 20' footer for sure. '96 KLR, '06 HD VROD, (girl friend hauler), '05 HD Electra-Glide, heh it's a HD and I'm old now ;-) and I'm proud of riding a 800+ pound bike at my age :-)
