Hi all, New to the group and hoping to tap into your knowledge. Also hoping I'm posting in the right place. Please excuse me if not. I live in NE Minnesota, and am looking for a WH tractor for mowing and snowblowing. I have a couple of questions I'd like your opinion/knowledge on, mostly about snow blowers and steering: Did all 520H/C models after 1991 have gear reduction steering? How do I know if a machine has gear reduction or not? Do the newer xi series have gear reduction? I think the 520/2/3xi offered power steering as an option, but do non-power steering models incorporate gear reduction? I'm leaning toward 2 stage blower, just because it seems heavier duty, and it snows a ton in NE MN. Are the 2 stage units worthwhile? I was lucky enough to work for Toro for a few years, and really want to find a red machine. Lots of green around here, but hoping to stay RED. Thanks for your help. Greg
I am considering repowering my 522xi (for various reasons, but that's not the issue here) and I need the help of some experienced people. Sorry this post is a bit disjointed, I wanted to condense my thoughts without creating a bunch of new topics. I believe that the Kohler CH730 is a near direct fit for the Kohler CH22S that is in the unit, does anyone know this for sure? Best I can tell it is. My first issue is with the PTO shaft. The replacement engine I have a lead on has a (proper diameter) 4" long shaft with a 7/16-20 1.5" deep threaded hole on it, the one that came in the 522xi has a 3-5/32" shaft. I am hoping to run it as is, but it looks like it might come dangerously close to the battery, and I dont know if that 27/32" difference will cause the PTO belts to run all amok. How does the PTO attach to the driveshaft, just bolted straight on? If it is an issue, has anyone cut a crankshaft before? If so, how? Will there be enough threads left for the PTO bolt if I don't have the crankshaft re-drilled and tapped? I called one machine shop that rebuilt my K341 and they said they couldnt do it, but I may check with others. Thanks in advance everyone! I changed the topic title to reflect my project that was based on the original topic.
Any point in considering this: to fit an XI series? Obviously the hydraulics are an issue but the XIs have that front PTO right up there... Never thought about using a 12v hydro on a WH but I do have 2 of them. $400 for a 44" Sweepster if I hurry!
So, out of the blue on Sunday, i decided to yank the engine out of the 518xi, to clean behind the engine covers. I'll gladly write up a how to. It wasn't very difficult. I'd guess i spent maybe 4 hours, taking my time, including a few short breaks. The engine runs a bit hot when mowing, during the summer. The gauge will pass the half way point, and goes to about 3/4, when mowing. At this point, i usually would take a break and let it cool down a bit, before continuing. So, the engine cleaning was on my list before the summer. Anyway, i was pretty disappointed to find it pretty clean. There was only one spot with a bunch of gunk, and that was behind the starter. I used my blow gun (compressor) to blow into that spot, and got some chunks of what might have been a mouse nest. Otherwise, the engine was pretty clean. I removed the fan, and cleaned the fins. They had dirt build up, but not too bad. So, why is the engine heating up? Here's how i did it. 1. remove side panels and hood. The hood is 2 bolts (the ones that hinge). Just remove the connectors for the headlights first. Remove the 2 side panels and the 2 bars running across the top of the engine. 3 bolts each. Easy. 2. Remove the battery. You can probably do it with the battery in, but i had to disconnect it, and that meant undoing the mount. So i yanked it. 3. Disconnect the wiring. There are a few harnesses on the right side, and a few on the left. Mark everything, and remove it. It's very easy. 4. Disconnect the fuel line. Don't get fuel in your eye, like I did. 5. Disconnect the throttle and choke cables from the engine. Mark where they were, if they are currently adjusted correctly. 6. Unbolt the driveshaft from the engine. This is the flex disk. 2 Bolts. Pretty easy. 7. Remove the 4 engine bolts. This is the hardest part. The front 2 are up above the front axle pivot. So, it means short turns of a wrench. Easy, but a pain. 8. Check everything. Make sure the engine is loose, and that all connections are free. 9. Pull it. I used my backhoe. It's not that heavy, but it's much heavier and more cumbersome that you can't pull it off yourself. Even a very strong guy would have trouble wiggling it out without damaging things. 10. The engine panels come off with some small bolts. To do it, you have to pull off the crank pulley (not sure what you call it, it's not a pulley). 2 set screws, and tap it off. Then unbolt the engine fan. Then the front cover comes off for cleaning.
