Outdoor Power Equipment and Small Engines - Noma Eaglestar engine pulley

I aquired a Noma Eaglestar riding mower, which I understand was made by Murray. The engine was all blown up when I got it, missing the engine stack pulley. I found a suitable replacement engine, an 11 hp Briggs and Stratton engine that looks identical to the 12 hp engine that came out. However neither engine has the stack pulley on it. The model number of the mower is D3912150. Any help would be appreciated. I checked ebay but it looks like there are quite a few different pulleys out there. I suppose I could just buy one and hope it works.

The Murray part number is 326563, but is no longer available. I suggest doing a Murray dealer search and check with as many as necessary to see if they happen to have this part on their shelf. I checked my shelf but do not have this part. You can certainly simply use two seperate pulleys but this may be difficult to determine and find the sizes you need and, more importantly, keep them in position.

The dimensions of the pulley stack is 4.00" OD top pulley, 1.00" ID shaft, .80 from the center of the top pulley to the top of the stack, 4.75" between the top & bottom pulley and 5.50 OD bottom pulley. Part number 326565MA is close only difference is 4.40" between the top & bottom pulley and 5.00 OD bottom pulley and is still available. 326563 crosses to 341226 also NLA but you could look for it to.
