My i170 seems to be developing a problem. - Page 2

When you remove the old elastomers, observe how they are oriented in the coupling. There is a right way and wrong way to install them. One side of the elastomer has little shoulders (barely noticeable) that fit into notches on the back of the plastic coupling.

Thanks Pete, I read about that in an old thread here, prob'ly one of your old posts (can't remember who mentioned it, but understood its importance). The parts are on their way, so I hope to be mobile in just a day or two. While I wait, I'm cleaning and maintaining - and copious pouting because I can't glide until the parts arrive. Friends are great and willing to go to the store for me, etc. But I hate depending on others.

Make sure the female coupling (the gear box side) is not damaged, looks from the photo it doesn't look that good, if the cupeling has a little free play from the metal gear box input shaft, it need to be replaced as well

The lower coupling is the worn out part

Both couplings seem to be in good shape. There is sticky/gummy residue over them, but I will clean everything well before putting the new elastomer on (Steve and his "mechanic" called it an elastomer). Think I can clean everything with alcohol? Something else better?

I like to use Simple Green for cleaning unknown plastics. Alcohol can be safe for some plastics, damaging to others. Acetone melts ABS plastic.

I have some Simple Green. Thanks.

I got the "elastomer kit" today. I didn't get it until just a few moments ago because it was delivered to my neighbor. I expected only to get the rubbery part that fits over the plastic (nylon?) gear, but I got both parts.

Click for full-size.

I can remove the old neoprene sleeve (I really don't know what these parts' real names are) from the original gear, but since I have the plastic gears, I might as well change those too. Not sure how to remove them though. I'm guessing the gear is just pressed on, but I want to be careful about removing it from the hexagon shaft.

Any suggestions?

Jim

since you have the whole kit you might replace the male plastic hub as well, it is just pushed on and shouldn't be too hard to pull off, however we do have a extractor kit, it's just a self made three piece metal hook, which grab the hub on three points for easy removal.

It's ok to use two flat screwdriver to ply it out, don't worry about damaging the outgoing part as you are replacing it anyway.
