The Bobcat M500 back together

A few weeks ago, I wrote about working on my Bobcat M500. I had to take it apart in order to pull the engine so I could get the starter off of it. The starter was in need of repair – the brushes were completely worn out. I also had Jack (the local guy who works on starters) check the generator, and it tested out fine, thankfully. That meant that something else was causing it not to keep the battery charged.

While I had the Bobcat taken apart, I cleaned it a bit. It had quite a bit of grease and grime on it. It probably could’ve used a good power washing, but since I didn’t have access to a power washer, I used soapy water, a brush, and a rag. I also purchased some cans of cheap spray paint and gave it a new coat of paint. It was nothing fancy, just something to cover up some of the scratches and places where the metal was bare.

While I had the engine out, I discovered it needed new head gaskets. Amazingly, new ones are still available – Kohler doesn’t support the engine (K662) anymore, but they apparently still have some engines that use the same head gaskets.

After getting the new gaskets installed and the repair starter on it, I completely rewired things. I welded a corner of the operator’s cage which had come apart (it’s home-made by a previous owner) and gave it a new coat of black paint. I also painted the wheels and rear weight red.

Putting it back together went well. I had to replace a few bolts that hold things together. Of course, when I had the engine back in and before I had all the other things put back, I checked to make sure it would start and run okay. It did.

After getting it all back together, I had to run it and check things out. It worked well, but I noticed the batter wasn’t charging. I suspected the voltage regulator, and, when I tested it, it was clear that it wasn’t working (it regulates the voltage from the generator for charging the battery – alternators have built-in voltage regulators). So, I ordered a new one, and when I arrived I put it on. it solved the problem.

The only other problem I had was that the air filter needs replaced. I still have to find one or figure out a way to put new filter material in/on the current one.

Since I got it back together a couple of weeks ago, I’ve used it around here some, and it is quite handy. I’ve moved compost and have loaded some manure and bedding into the truck to haul it to a compost pile. The only complaint I have about it besides that it’s almost underpowered (it is amazingly strong for its size and small engine) is that it drinks gas at an alarming rate. These old Kohler engines aren’t known for being fuel efficient.

Yesterday, I hauled the Bobcat to the stock yard in town. The company that owned the stock yard went bankrupt. So, it’s closed. Anyway, before it closed, the guy who ran the place had the power company tree trimmers dump several loads of wood chips for him to use in their back lots instead of rock (wood chips would keep the cows out of the mud). I liked this idea (it was my idea), because I intended to get the wood chips and manure later on.

However, since the place closed, the pile of wood chips has just sat there looking forlorn and lonely. When I asked, I was told that I might as well get the wood chips if I wanted them. So, I used the Bobcat to load them on my truck and bring them home. I used my smaller truck and trailer to haul the Bobcat, and then after bringing home a small truck load of manure/bedding (all that I hadn’t already gotten – I left it in case anyone else wanted it, but it was still there after four months), I drove my big truck back. I loaded and hauled six loads with the big truck, approximately 72 cubic yards of wood chips.

They’re all piled nice and neat here on the farm, now. It’s very satisfying to push things into a nine foot tall pile for some reason. We’ll use wood chips for garden walkways and to mulch around trees. When I get some more manure, it can be mixed with them. If they’re just left to break down, they’ll make some excellent compost on their own.
