Lo-Boy 185 Clutch Size

Postby kingfish9er » Tue Feb 12, 2019 5:35 pm

Good Afternoon Everyone,

Before I begin my first post, please forgive my ignorance and lack of tractor knowledge. I have extensive experience in building dirt bikes, working on vehicles and maintaining an M1A2 SEP Abrams Battle Tank, but that's about as far as it goes :)

I recently came across what I thought was a good deal on a Lo-Boy 185 for $400. It runs, no smoke and the hydraulics work. The seller told me it had a new clutch, it just needed to be adjusted. It also needed a battery, so I couldn't test drive it there. In my excitement and sheer ignorance of tractors (This is my first one), I took his word for it, we pushed it on to the trailer and I headed home.

When I got it in my shop, I threw a new battery in it and it cranked up after some slow turns. When I attempted to put it in gear, they just grinded.
I went ahead and pulled the shaft cover off and saw that the springs on the pressure plate were depressed, the friction plate was worn and the pucks were melted.
So I went ahead and ordered a new clutch kit and pucks, but I didn't think to measure the clutch size. The clutch I got in the mail is 6.5"

My question is: Will the 6.5" clutch work? I mean, the rear pressure plate is 7"... I know the throwout bearing for the 6.5 won't work but everything else seems like it wouldn't be an issue. To me, it seems like maybe a bigger clutch would be better anyway - like an upgrade.

I hope I didn't get screwed out of 400 bucks, but I like a good project as long as it doesn't become a money pit. If anyone lives near Dallas, I am looking for parts for this thing so I can get it looking and running better.

Thanks,
Matthew J.

Check out Hamilton Bob’s web site at the bottom of this page. He shows and sells the correct kit. Compare it with yours.
There are two clutches on the 154. Engine and PTO. Sounds like you may be looking at the PTO clutch.

Thank you for your service.

Welcome. You didn't get screwed for $400-. Actually that's a good price for a parts tractor, so you done good.

After one more post you can access and down load free manuals on this site, Quick Links, top left of this page.

Suggest you purchase parts from the advertisers on this site. Parts fit, prices fair, service is good, knowledgeable folks. Hamiltonbob's specializes in the numbered Cubs.

Money pit, depends on if you use the tractor or not.

This is the page you need. Notice that he lists the clutch size as 5.5"

The manuals would also help. Get your second post for access.

The both the engine and PTO clutch have some very specific adjustments/measurements. Obtain or down load the Operator's Manual, Parts Manual and Service Manual. You will need the information contained in the manuals.

Thanks guys. After some research, I understand there are many options on where I can purchase parts and get manuals. But my question still wasn't fully answered - I know it's the wrong size clutch, and I'm not trying to restore the tractor to OEM specs and drag it around to the county fairs - I just want to be able to operate it so I can clear some brush to make my kids a motocross track. So do yall think I would run into any major issues if I went ahead and installed the 6.5" clutch? I haven't even checked to see if it will fit on the drive shaft properly yet, but if it does - and the throwout pushes the springs down, do you think I'll have any future issues with the added weight on the drive shaft?
Sorry for being so difficult.

Thanks,

Glad you are returning the wrong clutch kit.

Clearing brush and making a motocross track. I own a numbered Cub, good lawn mower, not very good at anything else.

Works great with the tiller as well (if you have a creeper and 3-point)
Works good with the blade for pushing snow (if you have chains and wheel spacers)
Works not so great with the model 50 snow thrower. (Also need a creeper, chains and wheel spacers) I hear that the McKee 320 blower performs better.

$400 r u kidding me you can find a cub cadet for that price lately, non running. My number 2 int154 cost me $400 its a parts machine but my project.

I used a sub soiler on my 3pt on my 154 to loosen up big rocks sticking out of the ground.
Plow dirt and snow. They can do more than mow, my local lawn and garden repair guy calls the 154 a mowing machine. With the plow, tire chains and wheel weights is a must with 8.3 ag tires, to put chains on the larger 16.1 rim turf tires you need the spacers.

On my number 3 int154 with the snow plow setup in high range the clutch would slip. I found out the pressure plate had one spring the other two were broken. She pushed snow in low range on one clutch spring.(creeper)
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

$400, you could throw about $1000 to $2000 at it and break even, you did well. Also, take note of your serial number. the last 5 digits tell you what year it is, there were some differences between the years, not major but just little fine details. get the service manual off this site and any other manuals you may need. if you worked on a tank, that tractor shouldn't be an issue for ya. I love my 1975 185
