From when I owned 520-H tractors, this is an Onan remote filter adapter 122-0369 and remote filter base 122-0476. One of the problems with the 520-H is the oil filter and base blocking the airflow across the rear cylinder. This will help by moving the oil filter out of the airflow. You could also adapt a small inline oil cooler at the same time. The old gasket is still in place but I would suggest a new one. There is a port for the low oil pressure sensor on the adapter. I suggest cleaning the relief valve. New hoses of the correct length would be required depending on where you mount the oil filter adapter. Also a plate would need to be fabricated to close off the oil filter hole in the shroud. These have been discontinued for years and are no longer available from Linamar/Onan. Used and sold as is.
Good morning gents. Picked up a 516-H the other day and finally got to tinkering with it. Keep in mind it was a sub $400 purchase so the plow and the fact that it runs at all is a good thing. Now when the air filter cover came off it was dripping with a mixture of gas and oil. Seems like it was blowing out of the breather maybe? Then after the old oil was drained (or should I say the 30:1), new oil was added and it was run for a few minutes. Oil was drained and it reeked of gas. Any suggestions on how to tighten this up? Motor need a valve job and rings? As always, your input is valued and appreciated! Here's some pics of exterior motor.
I have a wheel horse 516-h and I am looking to swap in a kohler single cylinder model like a k-341 or k321. Or a magnum series single cylinder. Does anyone have any idea what the swap will entail, what parts will carry over and what things I should look for on the kohler. Also I believe the mounting plate on the current set up can be removed to fit a kohler perfectly like they would be set up on like a 310-8. In new to wheel horse so I appreciate anyone's help! Thanks!
Hello fellow Wheel Horse fans,
I have owned a 312-8 for a few years now, and it has been very good to me. The unit was obviously purchased used, and at the time of purchase I didn't notice that the 42" deck that came with it was much older than the mower. The deck I have has always been pretty junkie, but now started to have some actual issues. The center double "D" pulley has rounded out, and a spindle has broken. I have been looking into getting repair parts, or just buying a different deck all together since i can't find very reasonably priced ones. So here is where the question comes in.
I have found a reasonably priced unit in the area for sale that is a 516-H model. So a little larger engine, year or 2 newer, a 48" working deck, and hydrostatic would be a nice upgrade for me, but it sounds like this model was considered undesirable. Is this just because of the technology that was starting to exist at the time of it's release, or was it considered to not be that great of a machine? My 312 has about 1800 hours, and the mower itself runs great. The 516 apparently does not have working gauges at the moment, and burns some oil.
Any opinions on what you guys would do in this situation? Any opinions between the 12HP Koehler and the 16HP Onan engines?
Any help would be appreciated, Thanks.
