Sounds like something binding somewhere.

Mine rolls easier with the belt than it did with gears.

I'd pull it apart and reassemble just to make sure.

I took it apart and the main gear seems to be binding would anyone have a pic so I can see how they sit together

Can you send a pic so I can see where you mean?

I would bit I already took it all apart the problem seems to be either belt drive or layshaft

The belt is the same on all of them do I'd be looking at the layshaft or bearings

I think it's the bearings in the gear plate everything else is new

Go to your local bearing store and get some high speed rubber sealed ones.

Do the whole gear plate while you have it a apart

Also check the free play of the brake pads, there are two set screws in the center pinion bearing holder to adjust for wear.

Good idea

I didn't think of that one

As soon as I tighten those two grub screws and install the pull for the belt drive it binds up but if I leave the grub screws loose everything is free WTF I don't understand help plzz

central gear holders have up and down direction, try flip over them, gear must be little bit down to chassis. There is cut in chassis gear to set in.

Take the shaft out and insp for bent or cracked

 

[chrisscott961]

It's as far down as goes there is only one way to install screws don't sit on other house

Do you mean the brake adjust screws? [where are the pads?] or the screws that are falling out of the ring gear?

If it rolls with the pinion disconnected I'd be looking at the brake adjusters though why they'd move when installing a belt I have no idea.

Obvious question I know but have you looked at throttle/brake servo to make sure it's not stuck?

 

[chrisscott961]

If you look at the picture I don't even have the brakes installed it's the grub screw that holds the layshaft and the shaft to the pulley when I tighten those two grub screws it binds the the car up.

In the picture it looks like you have a loose screw, top center, on the central gear. That may cause a misalignment. I would also check all shafts to make sure none are bent. I had a similar problem and found the cause to be a bent shaft.
