D7F vs D7E Undercarriage

There's another thread going on a D7F that I bought last month. Thanks to everyone for your feedback on that one.

Now for another question. I need an undercarriage, I knew that when I bought the tractor. I'm talking to a fellow member that has a D7E that he's parting out. My rail pitch is 8.50 and he said the 7E is also 8.50. I have 38 links but don't know the link count on the 7E rails as of yet.

I'm assuming if the sprockets/idlers are the same width and the link count is the same, then the 7E rails will fit the 7F.
So am I right or wrong? I wont' put many hours on the machine so I really want to find a used undercarriage to go for a while so I can assess the condition of the remainder of the tractor before I spend the money for an all new undercarriage.

I'm sure some of you guys know the rail interchange information off the top of your head.

Thanks,
Brent

The d7e and d7f use the same track 38 links

Hey Brent, I'm digging up an old thread here, but was curious as to how well the swap over went. I have a D7E and am also looking for some undercarriage for mine as well. Did everything interchange ok?
