Cat Ten

[Member2103]

I started this thread on the buy/sell side. Thought I better move it over here. I got a set of pins and bushings to replace my old ones on my Ten from John Deere.
Pins M2559T Bushing M2259T. The origional links are Cat. The shop called me and said the bushings are .0019 too big. The said they are afraid to try and press them in fearing the links might break.Has anybody else had this problem? They said they might be able to bore the links, or turn down the bushings. Any ideas?? Comments?? Thanks, Mark

Cat TEN rails are made from forged steel, not cast. I have used that exact bushing in TEN rails. Press em and use em. Makes for a nice tight fit.

Mine worked good only thing is the JD pins are tad bit longer

Mark,
I never have done what you are talking about, but I have heard about it being done several numerous times with success. Assuming you have the right JD parts, and links It should work well. What are the JD part numbers for the pin's and bushings? I have a regular set of cat tracks which i have to have lengthened by one link for a high ten, so i need two pins and two bushings.

I just thought of this. Will the JD master pins work for the cat tens?

[MARCOTEN]

jep masterpins will do, maybe with some grinding of the last link, as the masterpin of jd has a plate on the end and no wholes.also the jd pins and bushings are ok.
ust had mine done , and with succes!!,

I machined my own master pins exactly like the original ones when doing my
7C15.

John Deere Pins M2559T
Bushings M2259T
Master Pin TE433yt
Snap ring 5787yt
The John Deere bushing measures 1.383
The old bushing measures 1.365
The difference is .018
If we break a link or two trying to press these bushings in, how plentyful are replacement links out there? Thanks Mark

Big difference between the 0.0019 oversize you first mentioned and 0.018.
At that kind of press fit you could break them all.
Are you sure those number are right?

[Catmatt]

I have lots of links if you need them- not sure how there height compares to yours, but I have some.

According to my drawings,
Bushing-1.369-1.367''OD .883-.885''ID X 3.25''long
Pin- .873-.877''OD X 5-3/8'' long
Master pin- .870-.871''OD X 6-1/16'' long
Track Link- 1.357-1.361''ID & .866-.870''ID 5.75''centers X 2-5/8'' high
I had a set of JD pins&bushings done before with no problem probably should press with white lead or some other high pressure lube.

[Old Magnet]

That gives you a 0.010 - 0.012 range of press fit which is still pretty tight but probably doable. Lube would be recommended.

[Member2103]

Thanks., No I'm not sure I got the numbers right. I was driving down the road while talking to the shop. I'll print this and take it to the shop Monday. I think we'll try it and see. Thanks again... Mark

So why are Cat Ten parts at John Deere?

[WyoCat]

carlsharp, its not that. It is actually coincidence that JD MC pins and bushings are close to the original Cat TEN parts. Why machine new ones when you can get something off the shelf?

[Member2103]

I picked up the tracks from the shop today. New pins and bushings, and all new bolts. The John Deere bushings fit the old Cat links just fine with no breakage of the links. ( much to the amazement of the shop guys!) They did break two of the new bushings pressing them in. I guess the steel in the old Cat links is better than the new steel in the bushings. Mark

The John Deere pins work great! Did mine over the summer

[catrjw]

I used the JD part numbers you have listed and they worked great. We did break one pin pressing it in so buy an extra. We did not break any of the links. The master pins work but you need to grind the ends of the link where the original master pins had small pins to hold them in on each side. Hope this calms your fear. Rick catrjw@aol.com
