Liquid Wrench and lots of it. Heat works too, but you have to be careful because you can ruin the part and the paint.
Having a very difficult time with the screw on the front fender - that goes into the fork. Will not budge. Help.
A picture would help. Mine has a brake in the front and the fender attaches that way. I'm assuming you've got a single screw underneath? Liquid wrench and careful pressure. If all else fails, you can weld a bolt to the screw head and turn it like that.
What size crescent wrench will I need to remove the fork from the frame? I'll need to buy one.
I have headset tools, but a #10 should fit your locking nut. The rest of the headset will (should) come apart by hand.
I assume I will need a crescent wrench for the front sprocket as well. What size?
For the bottom bracket locking nut you'll need a #12. You'll also need a tool for the adjustment race. Both of those are threaded backwards (Righty-loosy, lefty-tighty). The tool depends on the race. For the locking race on the other side that holds the sprocket to the crank... well, I use channel locks because a #12 is too small.
In removing the front wheel from the fork - the axle broke. Suggestions on getting a new axle. Thanks.
I need to see a picture of this. I can't imagine how you broke the solid axle removing the wheel. It may not be the "axle" you are after.
Also having trouble with the goose neck. That won't budge.
For the stem (gooseneck) loosen the bolt so it sticks up a bit, then smack it with a hammer. It helps if you turn the bike over to get liquid wrench up in the head tube.
Peddles - won't budge.
One is standard thread, and the other is backwards. IIRC the left pedal is backwards. Either way, a 15mm wrench should get in there. But first... liquid wrench on both sides, and let it soak in.
Post pics!
