Greetings;
Finally made it up to my tractor this past week with a long list of things to do. I ended up taking off the hood of the tractor to be able to remove the exterior rad screen and to take a good look at the front of the rad and sure enough it's fairly plugged. It looks to me as if no one has ever done a cleaning of any kind. The oil cooler isn't in any better shape.
Once I took the hood off I had a chance to get a better look at the inside as well and to my surprise (read:horror) I could see that the white plastic rad fan wasn't moving. After watching for a minute or two I shut off the engine and checked the belts. Everything seems tight to me. I started up again and this time after some weird noises the fan did turn a couple of times and then stopped again although the engine was still running. By this time was getting a little dark and I didn't have time to do much of anything. Next weekend I will pull the rad to get a better look at the fan and pulleys to see what's going on. Draining the rad and replacing the hoses and clamps was on the list anyways. No wonder it was overheating!!
One thing I am curious about though is the belt set up. I don't have a workshop manual for this tractor but I do have a parts manual. In the PM it shows only one belt connecting the alternator, tensioner pulley and fan pulley. On my tractor there is one small belt running between the alternator and the tensioner (which has a double pulley)and then a separate belt running from there down to the fan pulley. I'm wondering if I have a newer tractor than I thought or an older manual. Anyone have any insights on that? Hope the weather is good next weekend. Although I love working on the tractor, being eaten alive by mosquitoes and deer flies does temper the experience a bit.
Cheers, Erik
