Well I used the farmboy for a while last week and air was still in system, I pressure washed every thing again, including removing drive motor covers and wheels. I have FINALLY found a leak, it might have always been there, but I could not see it before. After operating it in 100 degree heat for about 30 minutes I put it back in shop. Next day there is oil every where under machine and dripping out back door edge. It seems to be a short pintle shaft seal, if I read my service manual correctly? So I have decided to remove entire engine and pump assembly. fix leak/leaks and install new idler and belt, as well as suction hose on pump. I have a question regarding suction hose. There is a large diameter hose coming from left rear of tank on bottom and connects to pump on left outboard side of the assembly. That hose has hose clamps on both ends. IS THAT CORRECT? I do have service manual, but it does not show a good picture of that suction hose. I would think it should be screw on connections, not whatever it is slipped up on with hose clamps. All of the hydraulic hoses have been changed at some point prior to my ownership, with two exceptions. One hose on bucket is coming apart, and this suction hose looks old. I would appreciate any and all comments or recommendation on my endeavor. I am waiting for cooler weather here in Texas before I start the removal process. The Kohler engine, which is a Magnum 18, runs well, and does not use any oil, so I will look it over while out, and clean it well before reinstallation. As I have said this machine will only be used on my few acres as a shovel, wheel barrow, and hoist for various loading unloading projects, and I plan on taking it to local farm/car shows, once I get it working correctly and painted. Thank you and best wishes. D.
