I picked this up a few weeks ago, the previous owner had it since new and had a local shop paint it and install new decals, (which were wrong, it's a B). He never noticed the mistake, but it cost less for me.
There has been some modifications to the ROPS as well, at least as far as I can tell. it appears to have been cut, 1x1 angle iron added and then bolted back together, why I'm not sure.
After finally getting the four Delivery Valve holders to stop leaking diesel fuel, making it a pain to start. previous owner stated to "hit the glow plugs for at least two full minutes before trying to start". so I figured I'd have to replace the glow plugs, as they'd be melted...turns out, they look brand new, and when I checked them with a ohm meter I got 1.5 ohms on each, between center terminal and ground, 15k between center terminal and working end of glow plug. so I hooked them up to an external battery, and they glow about 3/4ths up the plug, and do so in a hurry. still made me wonder about the reading I got, but, long as it's working properly, who am I to question it....lol
I found some other issues that need attention, unfortunately I have not found any info, as of yet, already posted.
First, I found a wire not connected by the starter, it is a White wire with a black tracer
Someone did a half hearted job at trying to insulate the bare wires, as you can see it's a "fail". I could not locate a terminal where it would appear to attach.
and of course, the machine does creep backwards, and I plan on tackling that issue either later today or tomorrow, using the information ya'll have posted already, I have to go get the bushings first, already have the new cams and can just flip over the bars.
When I raised the ROPS and was looking at what I had to replace to fix the creeping issue (and the very sloppy controls, a result of very loose bolts) I noticed about a half dozen or so different wires that are broken, some taped off, some not. they are located on the back left side of the machine as in the operating position, the harness that comes down from the ROPS, if I remember right, there is a connector there as well. with the amount of broken and unhooked wires I found I expected to find at least a few things that don't work, thus far, only the hour meter is non-functional,
I've been looked online for a detailed wiring diagram so I can repair the wiring, but have had no luck as of yet, the two service manuals I downloaded don't have the needed details, such as wire colors...etc.. anyone have any ideas?
I plan on documenting the repair and adjustment for the creeping issue (it'll remind me how to do it when it starts to creep again...lol) I didn't find anything already posted for the 743B, it's the one that everything is located on the side. and looks to be a pita to deal with...
Other than the above stated issues, it appears to be a pretty tight machine, even for it's age, low wear on pins and pivots, no play in axles, very little play in chains etc.
