184 clutch ???

Fri Aug 16, 2013 3:10 pm

Hi guys Im new to this site and having clutch problems. Can the splines in the center of the clutch strip out? Tractor lost ability to move and a god awlful grinding noise started. Thought ring gear and pinion had stripped or the splines on the driveshaft stripped. Started pulling apart and found all was good, all I can think of is the clutch. any help would be greatly appreciate

Hello Dan. Welcome to the best Cub site there is!

Probably not. The clutch disc could have other issues. The center hub of the disc could come loose and self destructed.

Dan184. I know the splines can wear out. Mine did put in new clutch and its fine. It works anyway. It would be better if I could change shaft to as it doesnt release all time like it should.

Thanks for the reply. How big of job is it to replace the clutch?

Dan:

G'day to you. The Numbered Series Cubs I am not all that familiar with as I do not own one, but I do have a few manuals for them. The Cub 185 Lo-Boy Owner's Manual (Jen Sales). Also the only real Service Manual that I have available is the IH-50 2004 Edition Complete Shop Manual.

The Clutch Section begins on Page 12 Paragraph 36. Hope that helps a bit.

There are a few items that can cause this. Remove the tunnel and side panels by dash to check.
Tractor off, keys out, in third gear, clutch engaged (foot off pedal). Roll tractor forward.

Keyway on transmission (or creeper if installed). Transmission turns, U-Joint does not.
Keyway on driveshaft at U-Joint. U-joint turns, Driveshaft does not.
Clutch Issue. (could be worn driveshaft splines or the rivets on clutch hub). Driveshaft turns, clutch plate does not.

Your tractor may also have an issue with the pressure plate. Can't diagnose this without disassembly.

Also need to consider if the transmission is stuck in neutral. Might need to pull the cover off the transmission top to verify that the shift forks and gear selector are working properly.

I have done very well using replacing parts from http://www.hamiltonbobscubs.com

I just tore mine apart last night after I joined the sight, my 184 clutch disk broke around the steel just outside where the shaft goes in about an inch was left spinning around the d-shaft. When I depress the clutch thus releasing pressure, you can spin the outside with scwew driver. Make sure you guys pack your throw out bearings with grease, and a good power wash of the rock shaft and areas are a good idea.

That's what I was saying, although that would seem unusual on a Cub, I have seen it happen on larger tractors with some rough clutch operations, i.e. Jr horsing around trying to lift the front wheels. :o

It's not that rare. Clutches can rust in that area. Some aftermarket clutches also have cutouts between the hub and the outer fiber disc. I can't see this being stronger.
The rivets can also give way that hold the center hub to the disc. This doesn't make much noise when it goes though.
