Has anyone heard of Duratech ???

@Tcemaint; I'd say you should have no fear of posting here at all. There are a lot of very nice people on this forum willing to share their knowledge. Having activity on the forum is what makes it a place worth coming to. Plus, you sound like a highly experienced guy in your area of expertise anyway.

This is my long-winded way of saying don't be shy about posting here. It is all welcome. Thanks for contributing.

The engin is 122hp cat c4.4

Just so you're aware, it's branded CAT but it's technically a Kubota design and manufactured for CAT (or in this case, for Duratech) at the Kubota plant by Kubota. Guarantee somewhere on it is the Kubota nameplate (not at all saying there isn't a CAT nameplate too as I'm guessing that's what you found to ID it as a "122hp CAT c4.4")...

I'm an HD diesel / equipment mechanic by trade and literally just rebuilt one of these motors bottom up 10.2 hours ago (it FUSED a rod bearing to the crank!!)

They're great engines till you have to work on them, then they're a real bear and officially only CAT can sell you parts (if you ever need to work on it yourself call a shop called County Kubota in NE Ohio, they don't give two shits about proprietory rules lol). Learned that when I needed 0.4mm oversized rod bearings and while CAT could see them in their parts system they couldn't order them and the Kubota dealers system wouldn't let them order them but County had the parts in my mailbox literally the next day!

Good luck with her, I know embedded computer controls scare a lot of people but the engines really do run well and more efficiently and clearner than the old non-computer controlled stuff.
 
Yep, they don't make or even work on the small stuff at all anymore, that's why it came to my shop instead of CAT.

Customer took it to CAT first, they wouldn't even entertain a rebuild, just sell him an assembled [new] long block for $16k then charge (no joke) 52 hours of labor to do the R&R and change all the parts over to the new long block.

Edit: by the way, the Mitsubishi turbo also had to be replaced at the same time, atrocious shaft play!

Final bill OTD at my shop was around 11k, my (wholesale) parts & machine shop total was 6200 including the $1100 service manual I had to buy for it.

Is it possible that the first engine they used where actual cat engines and the newer ones are Kubota? The only reason is when I called Duratech and talked to the chipper mechanic he did mention something about this and said the newer machines were Kubota... or are they both Kubota and they just changed the branding? I’m curious to look for some Kubota branding on it now.. thanks for the heads up.
 
@Cereal_Killer; Welcome to the TreeBuzz forum! I think you are going to like it here. Really great first set of posts! I think a man with your background would be really useful to have around on a regular basis, as so much of the operations of the bigger players on this forum is dependent on having big machines running properly.

I don't know what led you here, but thanks for jumping in!

P.S. I really like your screen name. Wish I'd thought of it.

I'd put money on that one being it.

I believe when they went to c4.4 (emissions standards) is when they killed off their last in-house smaller stuff. Could of been worse they could of picked New Holland <shutters> or some other shit, I'll take Kubota any day lol.

@TimBr
Thanks for the welcome sir, a love of trees and [rec] climbing is how I found this place, just finally joined up now cause I'm thinking of pursuing a new career in 2018... Some of my ASE/ mfg. certs expire again this year and I'm getting pretty tired of that whole load of BS (I don't mind the constant tests, the costs for the HD side of ASE and for all the mfg. stuff is outrageous!)

Not that this field doesn't need constant training / certs too but my personal issue with mechanic stuff is how the moment you let any one ASE cert lapse, even just a minute, you can't claim master tech in any of your advertising / self-promoting / job-hunting till you retest. You have to hold every single sub-certification UTD at all times to be a master tech, they will come after you (technically you license the use of the ASE logo / name from them so they do have legal means to pursue if you use terms wrong. I've read / heard about some horror stories)

Anyway that's why I'm here. Love working on equipment, love it way more when it's for personal reasons and not a day job.
 
@Cereal_Killer; Having the ability to maintain your own heavy equipment along with an ability to climb seems like a killer combination for building a thriving arb business. It would allow you to scale the business up without going broke paying mechanics to keep everything running properly.

I hope it all works out well for you.
