My SVL-75 has been absolutely awesome, and reliable, except for couple minor issues.
1: There is no filler neck screen. Straw installed while fueling up ends up plugging the 90° inlet to the water separator/ pre-filter. Removed filler tube and placed course fiberglass screen over tank inlet.
2: Engine air filter would plug ridiculously early. Installed an Engineaire pre-filter in lieu of the OEM air cleaner cover. Problem solved.
3: The HVAC engineer needs taken out back and beaten. Assuming that the craptastic recirculate filters don't get sucked in, as the HVAC filters load up, the system starts sucking dirt from around the entire perimeter of the rear cover. This results in a fully clogged evaporator. Thicker closed cell foam helped a lot.
4: Before the first oil change, the power coupler hoses rubbed a hole into the engine oil filter. Relocated hose mounts.
5: I can't run OEM Kubota oil filters. On three separate occasions, the seal gasket has blown out, dumping all the oil. Running every filter but Kubota, and the issue appears solved.
6: The full length plate, that the muffler mounts on, sheared at both ends. Muffler inlet sheared, and the other end tried to melt a hole in an AC line. Reinforced it, rather that buying a new, updated bracket.
Machine now has 3000hours.
