John Deere aftermarket Parts

[redneckracin]

All, I have been having pretty good luck finding replacement parts from John Deere while working on my FIL'S 550 dozer. The prices from John deere aren't very good except for the seals and smaller items. I also have ran into some odds and ends that aren't available. Is there a decent place that sells aftermarket undercarriage parts for these older machines?? Thanks for the help!

I believe all the parts for the 550 are the same as the 450 and will interchange all the way up to the H series, so it's all readily available.

The sprockets and rails have a couple choices due to different bushing sizes. H-E Parts, Tractor Zone, Tracksnteeth, even Ebay will have what you need, for WAY less than dealer prices. I've seen track rollers down around a hundred bucks and sprockets for $135 or so. Like that.

I agree JD prices are crazy high. Had an idler go bad on my mini ex, they wanted something around $700.00 for new parts. Ended up rebuilding the idler my self and it cost me just over $25.00, been running it for over a year now with no problems.

Thanks lan! I have been searching around for parts but I have only turned up parts machines and bone yards. This might not be a bad thing, but I really don't want to buy used parts over the net from several states away. I'll check those sits out and see what turns up.

Any ideas what a bottom roller with the markings "SIMMEL D45E 7E" MEANS? I have one JD roller and 9 of these others. Several of them need seals and I have been striking out with the sites listed and even google. Does anyone have any ideas??

D45E is a Komatsu dozer, which triggered a brain cell, I seem to remember that Deere copied CAT chains and rollers for their dozers.

The Komatsu part number for a single flange roller is: 131-30-00320 Kommie may have used slightly different seals, who know what Simmel used.

Simmel I believe was swallowed up by BERCO years ago.

I think this may be the duo-cone seal: https://tractorzone.com/140-30-00040-seal-group-duo-tz1-1/

I thought it was a dk45?

 

[lantraxco]

dk45?

 

[redneckracin]

dk45?

The Komatsu model number. I guess simmel got bought out by berco?

 

[lantraxco]

DK45 I think it a Kioti farm tractor? Yeah, I think Berco bought Simmel right. Hadn't heard that name since the early 90's! LOL.

 

[redneckracin]

OH maybe that's where I heard it at! I talked to a rep? from Berco today, so that is the way I understand it. Supposedly he couldn't even cross reference the part numbers for the rollers even with the engravings on them. Looks like Ebay it is! On a side note, I looked up the tubes that cover the cross bolts for the rockguards from JD. 35+ dollars a piece!! for a piece of pipe that I'm going to just make by hand!

 

[lantraxco]

Pop one of those leaky rollers apart if you want to reseal them and get some dimensions, we can help you find seals and they're pretty cheap usually.

I think those tubes were schedule 80 or maybe even Shelby tube, but yeah I remember they came in with the bandsaw marks still on the ends, LOL.

 

[redneckracin]

I forgot to mention the guy at berco who said about simmel being no more said that the seals need a special tool to put them back together? Does that sound right? Yeah, the tubes are going to be cut up pieces of heavy wall pipe. JD is nuts for asking those prices on those cross tubes.

 

[lantraxco]

There's a wealth of information on here somewhere about installing those seals, only the first one is a bear usually, learning curve. The smaller ones like for rollers are much easier than the final drive hub seals that can be from less than a foot in diameter out to maybe three foot rings. Willie59 is the expert If you have the time to reseal some of the rollers, and the bushings are still tight, don't be afraid of them.

Yeah, those tubes always have been overpriced as I recall, but they sell them by the boatload, probably because the Deere shops replace them when doing undercarriage work on customer machines.

 

[redneckracin]

I have all the time in the world except for the nagging feeling I have for not having a machine up and running, the machine has been down nearly 18 months now. I didn't figure it was too difficult to replace those seals but it has been very difficult to get some part numbers for them. When I get some time this weekend, I'll see if I can find the non burnt seal and post up some dimensions. The other problem is 2 of the Simmel rollers have the bushings/bearings starting to get loose. I can move them by hand up and down if that's any indication. I found brand new rollers for ~$100 a pop, I only need to repair three of them so it might just be simpler to swap rollers and reseal the one JD roller that's left.

 

[lantraxco]

Yeah, if you figure your time is worth anything, new rollers at a C-note each is the way to go, then mebbe reseal a couple in your spare time as backups.
