Re: 420c 5 roller undercarriage specifications

Well I got her back together, new 350 rollers, regular link pin welded in for the master and 100 bucks in nuts and bolts all said and done. I got lucky doing some snooping at the local buva shops and found a fella that has been working with the undercarriages of these things since he was a boy. It’s...

Re: 420c 5 roller undercarriage specifications

Well I got the left steering adjusted like the book said best as I can tell. With the crawler running up on jack stands I was able to watch as the clutch disengaged the tracks as the brake was applied. Pretty neat stuff. I haven’t had any unintentional lock up yet on the jack stands but I’ll let y’a...

Re: 420c 5 roller undercarriage specifications

I pulled the finals bottom cover and found nothing besides a little bit of sediment but no metal glittering in the oil or metal bits at the bottom of the pan. Oil looked and smelled right. Gear teeth looked nice and crisp, the occasional minuscule chip but for being 60 years old I’d say it’s looking...

Re: 420c 5 roller undercarriage specifications

Pray about it! Haha, it did it twice when I started to make my way to the shop when I started to feel the steering acting up. It would whine some making a hard turn and I figured I’d better check it out before something goes bang. Both times I went back and forth in 2nd and R a few times then she wo...

Re: 420c 5 roller undercarriage specifications

Thanks fellas, I had been reading on here that 350 rollers can be substituted on the 40-440c models and found some options online $140- and up. I’ve still got Aprox 7/8” on my rails. I believe Lavoy had mentioned some where on here that at half inch it’s time to start thinking other options. Correct...

420c 5 roller undercarriage specifications

First off I should say that I’m new to the crawler world but excited to be part of the club. I recently purchased a 420c 5 roller and am now going over the undercarriage. The three center bottom rollers on the left track are wore through, the flanges are breaking off... yup shot. The two on each end...
