        I called it that because it’s actually the 1,000 hour evolution, but the machine only has 720 hours on it. Here is what I did.

        Removed four steering compartment plugs to check for oil. Dry as a bone except for some expected brake dust. There are two cast zinc 1/2″ NPT plugs, and two 1/8″ NPT plugs in the bottom.

        Drained the common sump of the transmission and bevel gear case. There is a four bolt aluminum cover underneath that holds a powerful 3″ dia. magnet. Just in front of this cover is a cast zinc 1/2″ NPT drain plug (I replaced it with a steel one). Hint: Drain the oil (about 3-1/2 gallons of 80w/90 GL5 gear oil) if you remove the magnet/cover. The magnet had a 3/8″ thick glob of ferrous impregnated oil attached to it. Proof that the magnets do work.

        Removed the transmission cover and thoroughly kero washed it out through the bevel gear case drain. Replaced both shift lever boots. Thoroughly kero washed out the bevel gear case through the magnet cover opening. I blew it all out with compressed air  and let it evaporate out overnight.

        Drained the final drives (37 mm wrench/socket for the drain/fill plugs) and removed the bottom covers for inspection and kero washing. No surprise bits or pieces of anything anywhere except for some remnants of that asphalt that was shipped in it when new. Refilled each final drive with about 3-1/2 qts. of 85w/140 GL5 gear oil.

        Changed engine oil (1.6 gallons Delo 400 15w/40 SE) and B-2 Baldwin filter (425 hrs. on oil and still good according to analysis). Changed fuel injection pump and governor oil – about 1/2 pint of engine oil.

        Greased all track rollers, idlers, tensioner springs, and dozer blade points.

          I can’t edit the previous post. The pics didn’t load right as you can see, so here’s the rest.

          Well, it seems I can’t add pics in a reply to my own post. Hal must be one paranoid person.

          I guess it’s a sign of old age when you become intolerant of things that don’t function as they should.

          I already quit TBN. But that was a different story.

            Well don’t quit here, I’m paying attention. Just start a new thread to edit if that’s what it takes to bypass the limitations of the website.

                also I got the skid steer working so I got about 1500 in it , I guess it worked out picking it up with the only cost was fuel to go get it. when it warms up will pressure clean it so I can find the serial # so I can figure out what model it is.

                    bob did you figure anything on the ford truck problem?

                    Yes I did. What I thought was going to be a $25k engine replacement turned out to be a $20 alternator rear bearing. What I determined is that when alternators are mounted rigidly to the engine instead of on brackets, any alternator sounds will be manifested as engine sounds, and at a much greater magnitude. I had hand-spun the alternator and it seemed fine while I was replacing the coolant pump, both belt tensioners and idlers, and both serpentine belts.

                    So on another note, I was going to replace all my turn signal light bulbs with LED’s because the regular 3157 bulbs burn up the plastic sockets. Ok, so I purchase an electronic flasher that’s supposed to fit a ’99 to ’11 Ford Super Duty. HA! I tear the underside of the dash apart only to discover that ’08 to ’11 trucks don’t use flashers at all, they have what is called a Smart Junction Box (SJB). The hyper flashing or “bulb out” indicator can be turned off with a laptop computer connected to the CAN-bus at a dealer………….. for a fee <sigh>.

                      David, I told you what model you had, but now I forgot what it was. :scratch: I think it’s in another one of your posts.

                        yes you said it is a 610 series skid steer but when I looked them up they ran a 4 cylinder Wisconsin . I have a 2 cylinder Wisconsin with no references in the history at Bobcat about that engine. All the fuel and hydro. pump attachments look like factory , like it is a original engine. Maybe it will have the same model # even though the engine is not covered . We shall see when I get the serial #. Then find out what the real model # is.  Glad it was just a alt. bearing. Things that make you shake your head , I have a 2008 ford ranger with a 2.3 the daughter has a 2008  ford fusion with a 2.3 mine has spark plugs hers has permeant  electronic ignitors. oil filters are different too. remember when if you had a same year and displacement 99% of the time they were the same, things were simpler then. yeah dash out not fun.

                          Ok, didn’t know you had a two cylinder engine. That changes things. You likely have an early 1963 model M444 which came with a 15.5 HP two cylinder Onan engine, or a later ’63 model M500 or M540 which came with a 24 HP two cylinder air cooled Kohler engine. The Four cylinder 24 HP Wisconsin engines didn’t appear until ’67 in the model M600.

                            well it seems that I do have a model 500 skid steer . But instead of the 2 cylinder pancake 24 hp k662 kohler that it should have someone did I my opinion a very good job putting a Wisconsin tjd 2 cylinder in line 18 hp in it.(it looks original, even the old paint matches  ) some of the mystery solved.

                              Good to hear David, but I wouldn’t be surprised at all if the factory DID install the Wisconsin engine.
