I needed a change

So I started another project, instead of working on the 50 other projects that I have going on already. I went to work on the model forty five road grader. It has 3 main issues to address, and I think it may be use-able, not perfect, but use-able. First, the gearbox for the circle rotation was not working. We were able to get the top cover off of that without too much effort, and found a set of tapered roller bearing on the worm gear shaft suffering from a lack of lubrication. Would of been an easy fix, except that some idiot in the past welded the U-joint yoke onto that shaft. That shaft will get a trip to the machine shop for either a new shaft being built, or a repair on the original. Secondly, the steering tires lean function wasn't operational. A drive chain broken may be the only culprit there, unless there is an underlying problem lurking that caused the chain to break. the chain cover was filled with water, so hopefully a rusty chain that didn't want to turn was the problem. We'll make sure that that gearbox is fully lubricated and such before just putting a new chain on and trying it. Shouldn't be the end of the world. Then the third problem, is the power steering doesn't work. Haven't had the chance yet to look at that problem. Hope it isn't too serious. The transmission does have issues, too, but it has at least one forward gear, and one reverse gear. That'll work for now. I hope this doesn't take a turn for the worse, and turn into another dead end project for me, like an HD5G that is killing me. I'll keep you all posted on what will hopefully be "progress". And the person who worked on this in the past; well let's just say that his (or her) Mama should never of let them play with a welder! Darrel

Does yours have the 516 with DETROIT supercharger on it???? good engines!---I think they said that was same engine as the HD-11 dozer. Did you get the manuals for yours?? I have mine around here some where, IF I could ever find them again! thanks; ac fleet

The supercharger might look loke a Detroit but ours has a Sweitzer plate on it.  The engine is basically the same as a HD 11 but has a longer front cam bearing with the blower drive.  So there are differences in the front timing cover area too.  No idea if they kept this when the fan drive was moved here on later 516's.  The HD 11 manual that I borrowed when putting the engine together covers this in cam bearing replacement.

Ours has been "farmerised" so wheel lean is hydraulic and it has hydraulic moulboard tilt.  Uses a second pump off the pto box for these.  I reckon the side shift would be handy for grading close to fence lines - from experience!

Darrel

With the original lean setup that means you'll have two drive lines to take apart if you have to split the frame - hope you're lucky or have small hands.

If you have to get into the steering box end of the power unit it looks (I haven't had to do this) like a lot of the seals ought to be standard o-rings.  Be aware that there is an adjusting screw - which you have to split the nose and get about a 6 inch gap to get to.

Thanks for the replies guys.
AC fleet, that's a bummer that your forty five got stolen. Was it ever recovered. ....? As far as the blower goes, yes it has a blower. To build on what Ian said, it is the same style blower as the 2 stroke Detroits used, but Detroit did not make the blower. Not trying to be nit picky or nothing just saying. I knew what you meant. I do not have the hydraulic side shift on the blade. I wish it did.
    Ian, with the wheel lean, I shouldn't have to do any frame splitting, I don't think. Should just have to put the chain on.
   Ghost, I think that the graders with power steering that is not working, steer harder than ones without power steering at all. The little bit that we have driven this forty-five, we do know that the power steering has to be fixed. Lol. I hope to get that AD3 running eventually, too, so no putting two of them together. Like I said in one other post a while ago, if I have a machine that needs parts, and buy a parts machine, then usually I end up having two machines that I need parts for, and no parts machine.
    I didn't get a chance to work on it today. Real work, in the form of fixing fence put a damper on it. Will see what that coming days bring. Getting dangerously close to having to prepare for spring seeding. Darrel

This is one of the BD-3's, never did get pic. of the parts unit!


thanks; ac fleet

Oh, I was also going to say, mine is set up to take a V plow, but I don't have one. It's set up for a snow wing as well. I do have that, but it's not on. Doubt I'll ever put it on, unless ole Shameless really gets carried away with his snow machine. I'd like to have a scarifier, but that probably won't happen. All my cab glass is gone, too thanks to vandals. And that, I can't take out of the AD3, because it doesn't have any either. Lol Darrel

Darrel

When you're working on the power steering take the weight off the front wheel with the blade lift.

If you get the steering to work that way (you'll be able to feel the pulses on the wheel) it will probably work WHEN YOU"RE MOVING but may not when you're still with the weight on the wheels.

Cat fixer son just woke me up to that as I thought I was in trouble again

Ian, I am not sure the whole story on the transmission, yet. If I remember right, it won't go into the gears. Darrel
