There’s a tutorial in the wiki on how to remove them. You need a special tool to do it, but luckily you can make your own from readily available hardware.

Re: Motorbecane v50

The whole shebang including the metal outer is pressed into the frame via friction. You need to make a puller. A socket the fits over the donut, and a smaller one on that butts up against the mount on the other side. Run a piece of threaded rod or a long bolt threw the bigger socket, the mount, and finally the smaller socket. Tightening will pull the mount out of the frame into the larger socket. Reverse to put in the new mounts.

Re: Motorbecane v50

You can either buy a puller tool (treatland sells one) or go to your local hardware and get the parts to make a puller. There is a tutorial on the wiki, here https://www.mopedarmy.com/wiki/Motor_mount_bushing_removal

Takes a lot of force to get them out. You can use the puller to install the new motor mount brushings.

hold on a v50 may be different.

Poor audio but hopefully usable advice

Don’t underestimate the difficulty of getting the mounts out of your frame, especially if you’re like me and trying to preserve original paint. With the tool or socket resting on the perimeter of the frame bracket, I wanted something between the big socket and the frame. I made a plastic washer to avoid paint damage. That complicates things, though, for putting a ton of torque on the puller. I bet the Treats puller has fine threads or something to increase pushing power. My homemade puller using a long bolt didn’t work. After you get yours out, post again here to share what worked.

If you are trying to preserve the paint you can always try to pull the old silent block towards the inside rather than the outside. Then the socket you are pulling into might mar the paint a little but not noticable like the face of the bushing land.

Re: Motorbecane v50

if your bushings (steel and all) were as ancient as mine were, I just used a hacksaw after getting the rubbers out. Spun and wiggled them with a vice grip after.

I pb blasted mine for two days, before attempting.

I made the puller tools on a lathe and it worked alright, you need a high grade steel bolt with grease on the threads for whatever route you take, a low grade bolt will strip out. Its important to get the spacing right without having to move them in and out. Take a measurement from the inside of the old left side one where the inner bushing touches the head to the flanged mount of the frame, and install to the same dimension so your pedal doesnt hit the variator. Set the right side one with the same gap as the old ones between the left and right where the head fits. I made a gapping tool out of a wood dowel to set it. There is probably a spec on the gap.
