Where can I buy ISO mounts for 1650?

The reason you can reuse the top ones is that the bottom isolators are the ones that get crushed badly. Many times the top ones are unhurt and can be reused.

Also, don't forget the two snubbers at the front of the engine mounts. Mine were crushed as bad as the 4 bottom isolators.

Just asking.

Thanks!

Bill I'm 100% sure they are not. Here's a video of factory ISO mounts after replacement from under the tractor.

Now you got me concerned...

My 1650 came with two sets of isolators, 16 total. The tractor had/has a 14 hp in it vs the 16 hp that came with the tractor. Somewhere along the way, someone swapped out the engine. The PO was trying to put these redish looking, very hard isolators in, but was having trouble getting everything to fit. He was doing an isolator swap with the engine mounted and I can imaging how difficult that was to do. So he decided the tractor was to old and the aggravation of adding the iso mounts was to much of a hassle and it found itself to me.

Having said all that, with the tractor came a box of extra parts. In this box was the 16 isolators I am speaking of. 8 of them were mashed and trashed. I feel confident these 8 were the 4 bottom ones used on the 16 and then 14 hp engines. The 8 good ones, I feel confident, were the ones used on the top. Thing is - all 16 are identical. There ain't no difference between them as far as I can tell.

I figure, I reuse the top isolators and use the extra 4 good ones on the bottom. These isolators are a touch ragged, but otherwise in great shape. I would be shocked if these were anything other than original IH isolators. All 16 look the same to me.

Soooo - what to do. If the top isolators are truly different, what damage am I going to cause using them on the bottom. Is the drive-shaft alignment going to be off?

Here are some pics of the good isolators.

Thanks!

The 4 on the far right of the Left side picture are somewhat OK, however, once you install them, they will 'squash out' fairly quickly...this is due to their age. If you re-use them on the bottom, you'll be replacing them within 1 year.

I agree with Wild Bill. If this was my project, I would use the genuine Cub Cadet ISO mount kit. You will need 4 kits, and they are in the area of 20-24 dollars for each kit. Were this me, I would replace the bolts and lock nuts too.

The instructions in the ISO mount kit ask you to tighten to 200 inch pounds torque. It is generally accepted that this torque specification is too tight. If you use this kit, (and I hope you do) begin with tightening the bolts to about 2 threads showing on the top of each bolt.

After using my tractor, I still had a considerable amount of vibration at this setting and I tightened the Mounts considerably to reduce vibration. For me, I am having good success with these mounts. Do the recommended engine cradle modification at this time, as well. You won't have any trouble for a good long time with proper maintenance and inspection.

Those look like all bottom mounts to me. With the IH mounts, the top and bottom are made differently--they interlock, one inside the other slightly. How he got 16 of the bottom half of the mounts, I don't know.

Bill,
You are not crazy. Those are the original style of iso-mounts, and truly are original equipment. Top and bottoms are the same. The mounts offered now were designed for the diesel model cc's when they came out, and over the years replaced the o.e.m. Ones. I personally prefer the ones you have pictured, yes, they do not last as long as the diesel mounts, but even if you torque the new style mounts as has been stated previously, they will still shake more than the "original" style. I have at least one of all the quietlines, from an 800 all the way through 3 1650's, and will let you test out all of them, with both types of mounts. But yes, the old style will not last 1/4 as long as the diesel mounts. It truly is personal opinion.if you are not mowing with it every other day, the mounts pictured will last much longer than what some people will lead you to believe

I agree. The very first QL I bought had bad mounts so I changed them all and kept the good halves. Top/bottom were the same. The next 3-4 QL's I bought, I just used the new halves on the bottom only and left the top half alone.

After using these tractors for several years of mowing after changing the mounts, they were parked and the tractors were replaced with something else. These tractors still have the mixed/matched mounts in them 30 years later in decent condition.

I don't know anything about the current replacement mounts. Never seen them.
