    This is what I was doing today. When we put it together last week we didn’t have the gaskets yet, so we just used silicone. It’s outdoors and rain was coming, so we needed to button it up. I also added the gear oil today.

    Started putting the oil back into the transmission, and noticed it was coming out the bottom faster than before. Doh! I don’t know what went wrong, I’ve done a lot of seals before without that problem.

    Also adjusted the front brakes. Followed the manual, it said to adjust until they drag, then build air pressure and step on the brakes a few times. Then adjust again, and back off three clicks after they drag. All seems good.

    I didn’t have time to do anything else. Next time I’ll put the wheels on, remove the transmission yoke, and try to figure out why it’s leaking.

    The transfer output is like this, it doesn't have a big nut on it. It’s leaking past the seal though, not the splines. My mechanic friend thinks the spring may have popped off the back of the seal, I didn’t think of that possibility. He wants to take off the retainer the seal is installed into, and look at it from the back side.

    I still can’t figure out where the block heater goes, I think what I got is for a later engine. The people selling these things are no help. Well almost no help, their product information says it replaces the water jacket plate on the side of the engine. They have two options, with and without water cooled compressor. Mine is water cooled. So I think if I follow the hose back from the compressor, it will go to where this thing installs at. It is just a pipe fitting though. I can’t find anything with two bolts like this.

    So I guess the question is, what/where is the water jacket plate?

    I don’t have engine manuals for this yet, the machine manuals only show a limited amount of engine stuff. It might show what I need to know, I will look.

    We just got a couple inches of snow, visible on a webcam thirteen twisting and turning miles away. I have no cover to work under, so I’m about to be shut down for a few months. Some years it warms back up (temporarily) after a snow, we’ll see.

    I drilled the hex plate, but only drilled where it was transfer punched. I’ll install with one bolt, and transfer the other hole location. That’ll insure it’ll fit.

    The image wouldn’t load, some are too large a file for this forum.

    This is what I found when I got there, plus there were three new trees down parallel to the loader just downhill. Three new ones across the main road, and two new ones across my lower road. And, I came in from the top in the snow. Neighbors came in from the bottom, and had to cut through twenty trees to do it. They were in a two wheel drive, going to drain the water in their cabin. I pulled them to their driveway, above ours, and got them turned around. It is raining trees, doh! I dropped another 9-10 in the area I want to move it to. Loader is ready to move, and another 3 day break in the weather is coming.

    Something to keep in mind.
    If you have any amount of snow be careful moving the loader. One would think they will go anywhere but those big tires can turn into skates pretty quickly. Don't want to see the machine or you getting any damage after such a fine job of repair.

    I thought the same, but I’m being told different. By someone I think has no experience with it, only his educated guess. He thinks the weight will take it down to rock quickly, and it won’t slide. There’s a good chance the snow will be melted by the time I get back up there. The snow line wasn’t much below our elevation as it was. Thanks for the tip.

    And “front brakes only” long enough to get it away from the hazard trees, what’s your thoughts on that? First thing in the spring we’ll do the rear brakes. First gear does hold it back pretty good on our hills too.

    The snow that is in your pictures isn't a problem. If you have a few good days coming you should be fine. It is not so much as holding it back as it is if it starts to go side ways. You always have the option to plant the bucket to hold it still.

    The tripod worked pretty good actually, got the job done. It took a few positions to walk it in there, that’s okay though.

    We made guide pins/bullets to help get the wheels back on, you can see one starting into a hole in the picture. The “grabber” had to come off shortly after this too, not enough room for it between the tire and loader arm.

    I made the grabber too wide, and the inner half kept coming out of the rim. The stick kept it centered. On the other wheel we kept out one of the two bolts holding the two halves of the grabber together, and it worked as a pincher. Worked good that way..

    We torqued all the lug bolts to 280 ft lbs lubed, as per the manual.

    Both front wheels back on, some snow is already gone where we were working.

    Temporary fix to the air cleaner cap, I’ll try and get a new metal one.

    I have a picture with brand name and part number of the garage door handles I used, I’ll get a replacement. Considering the potential for damage, I feel pretty fortunate.

    It was a torn seal, it’s good now. And oil put back in too.

    If you have a truck junkyard around you should be able to find a new (slightly used) bonnet for that air cleaner pretty reasonable.

    Hmmmm, we do. There’s a self service yard with a semi truck section, I wasn’t thinking about it until you brought it up.
