NH 488 Slip Clutch

[Draagyn]

Mower turns over by hand but slip clutch won't grab. Any temporary fixes until I can get it fixed properly?

Weld it together.

Disassemble entire clutch. Clean friction surfaces with solvent, wire brush, sandpaper, bla, bla, bla. Reassemble cleaned, degreased components and preload springs until it doesn't do that anymore.

Or weld it together and pray you don't swallow something that stops the machine.

Done all this. Removed springs and torqued down bolts as hard as I could and still slips.

Think I'll give it four little tacks with the MIG and hopefully they break if I hit something.

Is there a friction disc in there?? If its steel-on-steel it will only slip.

Obviously it is a very simple set-up....

Obviously the friction discs have checked out, or it would drive with the springs taken out and bolts fully torqued. What is left of the assembly is probably junk anyhow. He may as well weld it and learn how that can end.

This is really poor advice. But thanks for trying.

Have you worked on a NH slip clutch like this before? They are something special!
