    Where does old machinery go to die ?

    I've got exactly the same disease. I seem to have a hopeless need to fix up machinery. And the way you often have to pay for complete OEM parts, e.g. one of my excavator final drives went, so I stripped it down and found the central shafts in the planetary gear set had worn/bust male & female...

    Where does old machinery go to die ?

    Thanks for the replies lads. I'll have to dig a little bit to find out where stuff goes here (if not straight to the metal recyclers). Old Doug, what I'm looking at building will have forklift tynes, and a tracked base. The tracked base would be something like a tracked dumper would have. Even...

    Where does old machinery go to die ?

    Based in Melbourne, Australia. Just wondering, where does machinery that's ready to be retired, go to. Cars go to car wreckers, but I've never heard of any such thing for machinery. Machines like excavators, bobcats, tracked dumpers, forklifts, industrial machines, etc. I've got my own little...

    Cat 301.8 Radiator removal

    OK, so much for: there appears to be nothing difficult My re-cored radiator is now installed. I came across the exact same problem the op experienced and it's caused by a plain stupid design flaw by the manufacturer. On the 2 sides of the radiator are soldered 2 C-channels. These 2...

    Cat 301.8 Radiator removal

    I know this thread is nearly 3 months old, but I've just Googled about removing the radiator on the same machine. What the op said it true. The manual is a joke and hides the real truth of getting this damn thing out. Cmark & Nige, saying remove this, remove that is easy, but believe me...

    Technical Hydraulic Question on Main Pump

    Thanks guys. Each side (left/right) is a closed loop circuit. Wheel motors are in the chaincase, and swash plate drive pumps are under the seat (in the air). The aux gear pump creates a charge pressure in these 2 closed loop circuits. According to the hydraulic schematic the swash plate motor...

    Technical Hydraulic Question on Main Pump

    Got an old Clark/Bobcat 443. The auxiliary gear pump went and the only replacement was a "kit" for $2500. I found an off the shelf pump with the same mounting configuration and displacement for 1/10th of the price $250. Now, one thing I noticed about the old broken pump was that it had one...

    301.8 cat slew brake

    Took the pinion out of the motor today. Here's some pics. Hard to believe but that pinion was still driving on the ring gear. There's a section of the pinion teeth where they are worse and the excavator would "free wheel" at that point LOL. No luck finding a matching gear cutting tool, I'll...

    301.8 cat slew brake

    I got one made out of EN36A before. That's a high strength alloy steel designed for case hardening. I specified that when I went to the gearmakers. Seeing as I got 7 years of hard use out of it, it doesn't seem to be a bad choice. There's Bridgeport style milling machine in the shed too. I got...

    301.8 cat slew brake

    Ha ha, welcome to the club Chass. I've got the same machine and I've actually just been to the gear makers today to drop of my slew motor pinion so they can make me a new one. I'm also going to change out the ring gear (BIG job), and do the swivel seals while it's out. I did this repair 7...

    Volvo EC15B hydraulic thumb....home made.

    Thanks for that input Joispoi. I only just checked you machine specs and I see it's about the same size as mine. May be there is hope for me LOL. Well as far as attachments go I'm certainly in a good position for making my own now. The last 6 years have been like doing a long degree at...

    Volvo EC15B hydraulic thumb....home made.

    That sounds like the way to go. I bet you have a lot more control over your schedule too. Don't know how it works where you are but typical hourly hire is you get booked for a 7 or 7:30 am start on a certain day. Two or more other customers want you for that day and the day after is no good so...

    Volvo EC15B hydraulic thumb....home made.

    Happy for you Joispoi. I made a rigid thumb for my 1.8 tonner and it still makes me feel good when I use it, so I can relate to what you are saying. Hope you have more appreciation from customers than what I have had. Most don't even notice it and when I do use it they don't realise just...

    Videos of my home made line borer job.

    Thanks for the compliments lads. Sorry if my voice sends some of you to sleep LOL, I'm not the fastest of talkers, seems like it's in my brain but comes out slow from my mouth. I'm sure I've watched just about every line boring video on Youtube, so I could learn about this stuff. And yeah too...

    Videos of my home made line borer job.

    Had a thread going recently under the excavator section, about line boring my swing tower. Made some Youtube videos for anyone interested. It's more a beginners guide by a beginner so don't be too hard on me please :D http://www.youtube.com/watch?v=ZHSxLmJBD4Y I've certainly learnt my...

    Anyone seen a "clip-on" rake for a bucket ??

    I've just been asked to make a make-shift rake which will clip on to a seiving bucket. The customer only wants tynes which are about twice the length of bucket teeth. Bottom line is he thinks he'll be able to make do with this instead of a full blown independant rake, and he wants to save...

    Brush Rake for excavator?

    100 mm between tyne. Another guy I talked to on this forum has 2 rakes, one has 150 mm spacings for the "rough" sorting and the other one has 75 mm spacings. Making the toys look good has a lot to do with 3D cad. I can adjust the curves on the tynes, make the nice curvy ears (otherwise...

    Brush Rake for excavator?

    After over a decade of frustration I made a grab and a rake for my little 1.8 tonne excavator. All I can say is it's heaven when they are needed. Only problem for me is I generally do hourly hire for customers and none of them bat an eyelid when I load a bin with concrete in a quarter of the...
