3d printer

[DaRamblerman]

Any one with a 3d printer can you make these?

Gl 1200 rear bushing

Thanks.

[LeMaitre]

Printing it is the easy part.

The hard part is getting a 3d model created to print from. Then you have to choose what material to use in printing. It is not uncommon to have to print multiple copies until you get one with proper dimensions.

So does anyone have a 3d printer? I can send you the part.

[blupupher]

what part is it? There may already be a scan or stl file for it.

[DaRamblerman]

Rear air shock guide bushing. Thanks.

Very few GL1200 files that I've found so far - yeggi.com is a good search site that goes over the major libraries, but still not much.
Even if this part was printed, will it hold up? Printed parts are not as solid and strong as injection molded parts. Not sure that the potential wear and tear on this part is.

I could do it, but I'm in central Europe so hardly worth shipping a part to copy the measurements into a new design and then print to ship back. Especially if this is a part you can buy?

[DaRamblerman]

The part is not available from the manufacturer and was never produced after market. You can see what it is by going to partZilla rear shock, 87 Aspencade

[feedrate]

Ok I see - In that case, you could find a local 3d printing service, alternatively a local makerspace with people that can copy/design 3d model, where you hand over the part that they then can design a new one from and print.

If you cannot find this, and are ready for the cost involved shipping packages back and forth, then write me directly and we can figure out you sending me a part to copy and I can print one out and send back to you. If I can help this way I will.

Is the one in the pic an actual part? I'd guess it's in good enough shape to go back in the shock.
Only...is it supposed to be cut like that?

[DaRamblerman]

This is from a good shock. The split is supposed to be there. I broke one taking a shock apart and need replacement. Hope fully Some one here in the states should be able to make some.

I chased down that OE part number (52489-ML8-701). Apparently, the originals are rubber, and when available in the aftermarket, they were urethane?

I did find that 52489-KR3-003 superceded 52489-ML8-701. Search Amazon with that updated part number for details.

[Rambozo]

That part number is for the mounting bushings. The part the OP is looking for goes inside the shock body air chamber.
52472-ML8-701

ebay has lots of rear shocks for gl1200.

[DaRamblerman]

I know was hoping to get the part made.
Just ordered a pair off ebay. For the rest of you these shocks can be totally disassembled for cleaning. I had an overload bushing disintegrate and the rubbery goo caused the seal to leak. Which is why they were disassembled in the first place. Going to document it this weekend on the rebuild but you need something like a Brannick spring compressor.

[Bike...and Dennis]

When I did mine I didn't rebuild the whole shock, just the seals. That was difficult enough.

It is my assumption that 3D-printed plastic would not be a suitable replacement for a rubber bearing. The only thing close I would try is a TPU filament, but that isn't very strong under moderate heat.
There are of course better materials available, but those are very expensive and are made for even more expensive printers(not for home use).

You already bought what you are looking for, but if you want me to give it a try. Let me know

[DaRamblerman]

It's piece i needed is not rubber it's hard plastic.

[frebou]

I'm a motorcycle and a 3d printer/modeler enthusiast. I would gladly help with you project of duplicating the part. As someone said in the discussion, it's often an iterative process until you get everything right and you got to find the plastic with the right properties (heat/strength/flex). I'm in Quebec/Canada, let me know if I can help you modeling the part or printing it.

[jsmithrmga]

Just wondering... is the part too soft or rubbery to consider having it machined (subtractive) instead of 3D printed (additive)? If there is a material integrity concern, that might be worth a shot.

[DaRamblerman]

As the factory piece is plastic it would have be from plastic. I think it's plastic because it slides up and down the shock shaft. I can send you the broke part to look at.

[orthoDaniel]

I could do it! Or if @frebou wants to try, let him.
I got the software and printer to do it. I’m thinking ASA is what I will print in? How big is the part roughly? This could use a lot of filament.

[DaRamblerman]

What would we be looking at for cost? Thnx.

[DaRamblerman]

On another note anyone have a progressive shock with the aluminum housing laying around pn 416-1626? Thnx

[mito57]

Seems pretty easy part to model. I have the means also but would need the part to do it.

I need to know a litle more to determine best material to use. Is it static? If it slides, what's the sliding surface, interior or exterior?

Down you can see some of my work. I don't know how what others are asking, but if you cover all shipping costs, that's all I need. I'd do it just for the challenge.
