Help on d 4 cat

Post by Bobby H. » Wed Apr 20, 2016 6:28 am

I realize this may not be the proper place to ask these questions, but maybe someone can help or tell me politely where to go. I have a 1947 d4 cat with a d315 cat engine that I am getting fuel into the oil. where is the most likely place for that to happen? transferr pump ? injector pump seals?? Any help would be greatly appreciative.

It's been a long long time, but we had a D4 7U on the ranch that over the years had this issue a couple of times. One time it was the transfer pump....another time I had to pull the injection pump off and replace what I remember was a seal on the drive shaft. I don't have my books at this location or I would look in my parts book.
Hope this helps some.

Go over to ACMOC.com and register there. Them boys over there are the Cat experts.

I too have a 1947 D7, it's serial # is 18 indicating it's the 18th 7U off the line.

Thanks I found them just after posting and they have been a great help also. This what happens when you have toys from different mothers. I have the D4 and a 450c JD.

Hi,

Back in 1966, before he became the machinist in his brother's dealership, Dad was about to buy a D2. But, just before he did, the 420c was traded in. The rest is history, still sitting in my shed. Just used it day before yesterday. :)

I was looking for a 2 cylinder JD crawler when I bought the D4. For what they want for a JD in these parts as Lavoy can attest starts at 4G and goes up depending on condition. In fact crawlers in general are pretty spendy here. I gave 2380 for a running operating D4 with about 70% on the undercarriage and the ploy runs too. Couldn't walk away from that. Still would like to have one similar to the MC. That's the first crawler I ever got to run back in the spring of 72.

It is for sale now, we are just not going to get it done, and too many others to work on. There are 3 MC's sitting there now, 2 will be enough. Shoot me an e-mail, I think I have a pic somewhere.
