It appears my clutch is slipping too much. Is there any way to rebuild them?

You can epoxy in a new lining into the clutch bell! Tom

I made a mistake once, but I was wrong?

yep, cut the old liner out, put a new one in. make sure the shoes sit flush with the fan hub and are not sprung out any.

You may have to use one of the clutch liners available from the other manufacturers and cut it to size, carefully.

I removed the engine and clutch bell. What liner? there is about .040 clearance on either side of the flywieghts. So I looked on the net and Hobby King has them BUT I already have two orders waiting for shipping and at $1.49 the cost of buying them and shipping would be out of line for the value. SO does anyone out there have some that I can buy without being robbed? Thanks. Jim

eheh, what liner? there should be a liner about as thick as a few playing cards on the inside of the clutch bell. if you have no liner there, your clutch shoes are almost certainly sprung. check them, at rest, there should be no gap between the back side of the shoes and the fan hub.

if there is a gap, you need to take the shoes off the hub and squeeze them down a bit with a vice (or better yet, replace them) then bolt them back on. once the gap is gone, loctite them in place. MAKE ABSOLUTELY CERTAIN THAT THEY ARE ON STRAIGHT.

They appear to be close and uniform maybe I can upload a pic if that would help.

the back side of the weighted end of the shoe should contact the fan hub. if you were flying (or trying to) with no liner, the shoes will be sprung.

Good luck trying to find shoes for the Nexus. I had a buddy that it took about six months to get them.

I have some lining on the way from great hobbies. The shoe isn't far from the hub just a tweak should do it but you can't bend it in place enough to make a difference. If I remove it then damage from a vise would be likely. If the new lining allows clearance then do you think it will function or would it grab too soon. I don't want to bend it back if possible because that's when you can create cracks.

I don't think anyone wants you to crush it in the vise, just tweak it a little, ie. put wood in the vise to protect the clutch. I have never done this to a Nexus clutch, but I have done this to a few others. You will have no problem as long as the clutch isn't smoked already. Tom

putting a new lining in with sprung shoes will result in premature smoking of the lining because the shoes will not disengage at idle. Sprung shoes can also break off if they are not un-sprung. Then you'll be in a world of hurt.

like tommy said, you dont need to smash them in the vice, just put them in long ways and turn a little tension on them, it won't take much.

OK I can try that tomorrow I have Raptor30 size clutch liner on the way from Great Hobbies. Yes a tweak is about all they need I checked the thin part of the shoes under a magnifying glass after cleaning ETC and there appears to be no cracks. The clearance between the hub and shoes looks like about .020

To glue the liner in the clutch get some 1 1/4"(inside diameter) pvc pipe about 2" long. Cut length wise a 3/8" to 1/2" wide strip out of it, using a hacksaw. After putting epoxy and then the liner squeaze the pvc and put it inside the liner you will see it pushing outward the liner to the clutch bell. Try a dry fit first to make sure you have a plan and then add the glue. This works for me!

Sounds like a plan I can see things going wrong by doing it by hand and hoping for the best. Thanks I will try that, I also have to unspring the shoes and would using loctite on those parts be good or should I assemble it dry?

absolutely use loctite. but make damn certain not to get it on anything else. best to leave the engine uninstalled until the loctite cures. You'll be in a world of hurt if you end up loctitng the shoes to your new liner.

Let me get this right! Loctite on the shoe screws and epoxy on the shoe to liner bell or is it loctite on both?

loctite on the screws through the shoes into the fan hub, epoxy on the liner into the bell.

Great thanks. I machined up a sleeve last night to hold the lining snug in place once I glue it. Instead of splitting my ring at 90 degrees I cut it at 45 degrees to make the pressure more uniform and not end up with a bump in the material.
