Iso mounts????
 

I have this question buried in the back of my original post entitled Second Time Around but I don't know if folks will see it back there.So far only one response to it.Im not sure if what I have for ISO mounts are the correct setup.Im posting pics and if this is right or wrong can y'all plz let me know.According to the technical library post on ISO mounts what I have is wrong.Or maybe the way Im understanding it iswrong.Thanks.

Looks right to me :IH Trusted Hand:

You prob got them from ebay , those look like auto sway bar bushings. 12 to15 bucks at any auto parts store. A new set of iso mounts will come in a cub cadet plastic bag. And cost you 100.00

Here ya go..

I just got a set of ISO mounts (Cub Cadet as far as I know) that look exactly like what the OP has :bigthink:

What you have are not cub cadet iso mounts.

They are an automotive sway bar bushing that can be used as an alternative.

They are much cheaper cost wise than the cub mounts. I am currently trialing some of this type in my 1000. I have had them in for one season of mowing and have not had any issues.

The cub mounts are expensive and will be accompanied with the following instruction sheet.

Huh...well that kinda sucks then :biggrin2: The guy I bought my cradle and mounts from said they were about a year old set of Cub Cadet ISO mounts :bash2: Oh well, I'm not complaining because I needed new ISO mounts all around and these seem to fit the bill.

But since you seem to have the same set I do, how much did you tighten yours down? I did mine to what I had read (when I thought they were Cub Cadet parts) and left about one thread sticking up but found that wasn't quite the sweet spot. I have had exactly ZERO time to mess with it but if you've got a set you've been using, how much did you tighten yours down? How do you like them? :bigthink:

jimbob,

When I put the bushings in, I tightened till I had 2 threads showing above the nut.

I ran the tractor some and had more vibration and harmonics than I liked.

I tightened another turn and have about 3 threads showing. I feel the vibration is acceptable now.

It's kind of like salt and pepper to taste. You just have to play with them to get them where you like them.

I don't have money to burn but Ill spend 100.00 to get the correct part.As the machine is currently,its useless due to horrible vibration that I have never been able to get out.I have went tighter,looser and everywhere in between.I will call CC tomorrow and hopefully they are still available.Thanks so much:beerchug:

I replaced my ISO mounts with the Genuine Cub Cadet parts a year ago. I also used new grade 8 bolts of the correct size and length from Caterpillar, along with washers and locking nuts. If I correctly recall, the instruction sheet tells you to install the mounts to 100 inch-pounds of torque. That seems to me to be awful tight. I had a lot of discussion on this forum and basicly was told that I ruined the mounts at that torque. Not so, but I loosened the mounts to the recommended 1-1 1/2 threads showing. The mounts were so loose that they were able to be turned with the fingers. The K-301 jumped around so bad that it was hard to ride the tractor going down the street.

Finally, I just started tightening. I would tighten a turn and take the tractor for a ride. I played several days at this, and finally got the mounts to do their job. I think there are about 4-6 threads showing. The tractor now runs and rides nice, but still retains its affectionate name; the 1250 Nightmare!

Good luck with your project, and don't be afraid to experiment with the tightness of your mounts. You'll find the right place.
