Thanks for that information, I apologize for not monitoring this post, I didn't get any notification of replies. I am now looking for a drive belt, the variable speed belt. Mine broke yesterday. I do have the John Deere number, GG020-30843, and the parts manual says substitute for GG020-18058. From searching here and the net i may have found other numbers but I can't compare the dimensions because I can't find any for the John Deere part and my belt is so worn and stretched that I can't rely on it's dimensions. I think 2926v686 will work. The dimensions are 1 13/16" wide x 68.6" long. But the actual contact area, thickness, is half of the john deere part and I'm not sure I want to try it. I think the 2926v686 will fit the OMC 1200, do they use the same belt as the JD170, JD24, Owatonna 1700 ?? My variable speed front pulley isn't even hooked up, I set the speed and left it alone. I think a previous owner removed the hydraulic line and rotating coupler because the pulley leaked hydro oil. I have a grease fitting in the end and just pumped some grease in it while rotating the pulley to allow it to squeeze together and bring the belt to the outside or top of the pulley to get the most speed out of it. It's now really close to a 1 to 1 ratio so if I could find the parts to do it, I may just put a large chain and sprockets on it. I don't need the variable drive anyway. But, for simplicity I'd like to just replace the belt for now. In other news, the replacement engine is running great! I'll get some pics up soon. Crazy power, so smooth, starts right up, just incredible. I was able to fix a few hydraulic leaks while the engine was out as well and one was between the filter housing and pump so it was drawing air in while running causing slow hydraulics, now its so much faster and smooth bucket operation. Just for info, if you decide to use the V465 engine, the mounts need to be modified. I didn't know the previous owner had to do this until I removed the engine. Both mounts had to be ground or milled down to half the thickness for the crankshaft to line up with the drive shaft to the gearbox. I just used one mount from the old engine for the front mount since the cross member is welded in, but the rear cross member is bolted in so I flipped it to under the mounting tabs to lower it the required 1/2 inch and used the unmodified mount. Thanks for any help you can provide, and I will post any more info I find.
