Ok, I need to update.

I took the engine mount from the Perkins which was on the "back' end (actually by the fan) and modified it to fit the V2203.

The bottom part already fitted to the 825, so I just had to mount brackets to the side of the engine and adapt them to the existing upright side of the mount. I would set the bottom part where is had to mount to the 825 and modify the brackets to clear the engine components and still support the engine.

May not have needed the gussets, but better to do it now while I have room then to wish I did later.

Then I needed to fabricate engine mounts for the front of the V2203 that attached to the hyd. pump.

I started off with some plate I match drilled to bolt to the lower sides of the block, and was going to "somehow" get that steel to the holes where the mounts for the Perkins were.

After considerable CAD drawings (those are sketches on blank pages) I, with of the help of North Idaho Wolfman, came to the idea of a horseshoe plate with holes matched to the V2203 bellhousing. I put a piece of cardboard up to the bellhousing the best I could, because the bolts holding the support rods were in the way, and marked the outline of the bell housing. I decided 3/8" material is what I would use. That became a project in itself, but I stopped by the machine shop and asked Dave if he had any 3/8" plate that would match my cardboard pattern.

He had an odd shaped piece and I was glad to settle for that. He offered to use his plasma table to cut it out. That was interesting because he had to insert pieces of scrap material so the cutting head would make the radius. If there was no metal there the machine would stop! He also cut the inside radius.

I then matched the holes in the bellhousing to the flange, and bolted it up. However I did have to make a spacer to be sure the flywheel would clear the mounting plate. I took some 5/8" copper line, smashed it in the vise, cut notches out so I could bend a radius, and drilled holes to match the plate! Worked fine.

Then had to fabricate some steel to get over to the existing mounting hold. That's the last couple of pictures.

Oh another bit of information that was puzzling. I got a metric tap to clean out the threaded holes in the bellhousing because it's a Kubota, right? That was when I used a couple of metric bolts with the washer welded to them for the engine support.....

Those holes are NOT metric, they're SAE. Apparently Carrier special ordered those! But the tap I used cleaned out the muck and didn't cut any new threads. I think it was 10mm, and the bolts are 3/8". Another bit of confusion helped by North Idaho Wolfman.

Needed a new fan. The original was brittle. It's a pusher, not a puller.

Needed to get the air filter connected somehow. Used square tubing slid inside each other to telescope and mount on each side.

Been a while since I updated this.

A few pictures. One just to show it is running. Then the hydraulic reservoir which holds 26 gallons of oil. The picture at the foot peddles shows the plate underneath which has to be removed to get to a hyd. filter.

Dang Len, I never thought I'd call a Bobcat "gorgeous" but, that is close! Better not get near the dealer with that or they'll think you rolled it off their lot. Good on you for the effort. What is the plan for it now?

I've got a couple of pictures with the decals on it and it really looks different. Can't get them to post up. Keeps telling me "invalid post specified", so it must be a problem with my camera, computer, or ME!

Despite your picture problems:) ......looks like a damn fine machine! And an excellent job getting to the end.

How many hours you think you have in the total project?

A couple of picture with decals. I did not remove the ROPS (cab) so I have some touch up painting to get to. Other wise, I'm pretty much done.

Ray , you can also see where the paint couldn't reach when the ROPS was up. Got to get that also.

I'm seriously thinking about selling it. I'm 6'-4" and about 215# and claustrophobic. Those qualities make it difficult for me to get in, stay in, and get out!! I never had or ran a skid steer before and the new seat is comfortable, but I don't like being in a bucking box!

I don't blame you Len. I am not "quite" as claustrophobic but in watching guys run these machines, they always seem to be beating themselves, rocking and jerking, as they go about whatever they are doing. I like stable tractors that don't spank the operator.
