2 different sprockets style on 420c?

E.Huffman · Post by **E.Huffman** » Thu Dec 03, 2020 2:00 pm

I just found out my 420 crawler has a different style of sprockets on the front.. other words they are mismatched. One is like a solid steel wheel the other has the normal sprocket with cutout holes. Is there a difference in years between sprockets or did they make both in the same era? Just curious thanks!

Okay, might need some clarification. Are you talking about rear sprockets, or front idlers?

I am sorry I mean the front idlers.

Parts books shows both styles.

OEM disc front idlers for the 420/430 I am not sure I have ever seen a factor one. I have a couple of aftermarket ones to go on a crawler someday just for the fun of it.

I see! Yes I was just wondering if there was one newer than the other. Or if the crawler loaders were different than the dozers.

Nope, just an option.
