How do I get replacement parts for a childs roadmaster tricycle. I am looking for the white pieces on the end of the front forks that hold the wheel on.

Yes, you got the bolts too tight on the axle shaft. You have to "sets" of nuts, the inner and the outer. The inner nuts on the shaft, which go inside the fork, should be adjusted so the wheel is rolling freely, with just a tiny "slop". Now, you will need to figure out a way to tighten the outer nuts to hold the wheel on the fork without turning or moving the inner nuts! Some bicycle shops use specially thin wrenches.
Be blessed.

Try calling - 800 - 626 - 2811. They helped me with hard to find parts for my tricycle. Very helpful and very inexpensive!

Remove front wheel, brake calliper etc . Undo top and bottom yoke pinch bolts and slide out fork leg. Clamp chrome tube in a soft jawed vice and remove top nut carefully as it is under some load and will fly away, (but its not too much you can hold it with your hand). Tip out remaining oil slowly so as to not loose spacer on top of main fork spring. Clamp lower aluminium leg in vice by calliper mounts and remove allen screw in extreme end (if the wheel spindle was in you couldnt see it) This is the only part that might be a problem as the inner end may turn. An impact wrench may help or if not a simple broom handle shoved up the other end is often enough. Once this bolt is removed the leg will split. Now lever out the dust cover to reveal the wire circlip holding in the fork seal. Remove the clip and lever out carefully the old fork seal. Fit new seal using a large socket and mallet or something similar and reassemble in reverse order, not forgetting to add correct amount of new fork oil.

If I understand your request the list at Sears says all of those things are not available anymore.

You could get a whole new trike for $50 or cheaper used. Maybe transfer the parts from it. Look on eBay, Craigslist, other auction sites.

this ia question - does anyone know hoe to remove the pedals from a roadmaster tricycle ?

You need to hammer the cap on. The tube with open ends fits over the cap and lets you hammer it on. To make it work, you need something to hold the other end, like a block of wood, or I found a hockey puck worked perfectly. Assemble the rear wheels, then turn the cycle on its side with the cap end of the axle down. Put it on the block of wood or the puck, and then hammer on the cap with the help of the tube. Now if you can help me get the handlebars on, I'd be eternally grateful. Problem is the spacers seem to be too big to allow the fork into the slot in the handlebars, and without them, there is nothing to screw into to hold the handlebars.

I have no idea where you are located, but I assume you're on planet earth. If you're in the United States, file a complaint with the Consumer Product Safety Commission!

Here is a link for you. Do not delay! Take pictures too!

Yea, you gotta take the brakes off, the rotor, the axle nut, then you should be able to pry the spindle down far enough to remove the strut.

I think you may need a new bike.
