Hello all,

I have recently purchased a Cat D7E 48A-1198 at an estate sale. To say that my dozer knowledge is somewhat deficient is an understatement. I can’t wait to get this beauty running, and I need help! I’ve called my local Cat dealer and can’t get manuals (however parts are still available). The Cat dealer informed me that my dozer is a 1963 based on the serial number.

The seller advertised the dozer as having a stuck engine because it hasn’t been run in approximately 10 years and he didn’t want to mess with it. Needless to say, I got a pretty good deal on it - and my optimism peaks at stories like this. Of course I thought I could flush the fuel system and she’d fire. Not quite. Currently, I am stuck on getting spark from my spark plugs - it had Champion J12YCs in it, but I had read on another forum that it needed 18s, so I took this info to Napa and have got a couple ACDelco C45Ls to try. I’ve taken the magneto apart and replaced the condenser, and I can get spark there, but no cigar once the spark plug is hooked up.

Any and all help and suggestions are appreciated - and any tips on what else to look over and check!

Thanks all,
Al in KS

We enjoy pictures. What are you using for plug wires? Those old mags need solid core wire for a hot spark. Ebay is a great source for manuals.

kracked1: I’ll attach some pics to this post if I can figure it out! Incidentally, I write the original post while sitting in Napa while they built me some solid core wires. I had purchased regular ones at O’Reilly’s yesterday and was informed about my error by an older gentleman who happened to see me working on her. I’m getting ready to try the solid core with the new ACDelco plugs now.

dpendzic: I hope neither one is - I know the pony motor isn’t stuck now, but I haven’t made it to the main one yet.

From what you're saying, it sounds like the pony motor is the issue and not the main engine?

The 1952 D4 I just bought has a pony motor that is free and has compression, but hasn't fired in 10+ years. I'm going to try to get it running. But in the meantime, I can get the tractor going by pulling it with my truck. Get it going in neutral and then engage the clutch. The tractor starts up quickly after a few revolutions and is just fine. When I was looking I was also considering an RD7 and it had the pony motor removed, the seller said that he pull started it with another tractor and it did just fine. The obvious problem with this is that it requires two people.

Still, it's a workaround until you get the pony motor working correctly.

FlyingD4: Don't give up on the pony motor! This one has also been sitting for 10+ years, and she just ran for the first time! After switching to the solid core wires she was happy to start. I recorded her first start and uploaded to YouTube - here is the link

As far as the dozer being advertised as having a stuck engine, there were several rumors running around during the estate sale, but it’s pretty difficult to sort fact from fiction when people have different reasons for running something up or running it down. There was a story about sugar in the fuel tank, and a story about the exhaust cap being left off for an indeterminate amount of time and being rained in. Couldn’t verify any of the stories (even after tearing into it) although the diesel was clean enough that I doubt the sugar story - but I’m also not sure what sugared diesel would look like. -shrug-

It's a Powershift machine. Maybe pull it above 30MPH then shift it into gear.

Also I'm not giving up on the pony motor at all, I just have a lot of other projects so I've just not gotten around to it yet. It'll happen.

Daron: thanks for addressing powershift, I totally spaced it in my excitement over the pony starting.

I run both the pony and main out of a bucket gas for the pony and deisel for the main of course. Till you have a chance to clean the fuel lines and fuel tanks.
Just in case the rack is stuck I would remove the air cleaner and have a board to shut off the air of first attempt at starting the main by the off chance some one has fiddled with the rack.
Nice machine,
