ISO mounts questions

[rdeyoe]

Tearing into my 1450 now. I knew the mounts were terrible when i bought it, the engine was trying to exit the tractor. Got the motor out (pretty easy with only one bolt in the oil pan), and saw the flattened lower ISO bushings. I'm thinking the uppers may be usable, pretty old though.

I've already read just about everything on these mounts and options for them. I studied around for a while on options (solid, car bushings, etc.), not being able to put the newer Cub Cadet mounts in. I happened upon some isolation mounts on ebay (not the aftermarket ISO bushings someone's selling). I measured my cradle holes...seem about 7/8" on the ID and the OD from the old mounts was 1-1/4". These mounts are 3/4" ID and 1-1/4" OD with 3/8" steel bushing. They're recommended for a 3/8" mounting plate, so i figured clamping them down to the 1/4" cradle would expand them a bit. I heard the newer Cub mounts were kind of hard, so I asked the seller for the durometer scale of his. He replied that they're a 40 shore scale....pretty soft (does anyone know the scale on the originals?). Got them in today and they are soft....about as soft as my originals. Plus, they were only $20 for all four, worth a shot.

Some pics of the mounts free, loose on the cradle and mounted to the frame. I clamped them up with some larger washers on the top side that has ID larger than the steel bushing. The seemed to clamp up very nicely. The space on the lower side is a bit less than 1/2". I have the bolts tightened all the way down to the shank.

Has anyone tried these? Other opinions? Can anyone give me the height measurement of original mounts? It's going to be a while before I can get the motor back in to test, but this cradle seems to have good isolation and firmness. Have to repair the oil pan from all the banging around it did in there and get the cradle mod done....
