    D6R shifting hard when changing direction.

    D6R - 5LN02305 The machine has had an intermittent issue of shifting hard when you change directions. I did the fill calibration and it solved it for about 20 hours. I knew that there was a newer style modulating valve to put in these older transmissions so we put the newer style in it and...

    D6R II LGP shifting hard

    I just put a new transmission in this machine. I calibrated the clutch engagement pressures with ET and it operated great. But after it ran for a couple hours it shifts too hard when you click into first gear forward, it shifts hard into reverse also but not as noticable as forward. I went...

    Deere 544H park brake unresponsive

    So I'm working on a parking brake issue on a 544H loader for a customer of mine. The park brake indicator light in the dash never illuminates. The machine just flashes "stop" when you move the shuttle shift lever to "forward" or "reverse" regardless of what position the park brake switch is in...

    Deere 850J with "slow to react" right hand drive

    Customer of mine recently purchased a Deere 850J dozer. If you hop in it and take right off the right side won't pull until the machine warms up. However, if you start it and let it sit for 30 minutes and let it warm up without moving it, it takes right off and has power to both sides. Upon...

    PC120-6 - oil in the bell housing?

    Just had a customer call asking how much oil should be in his bell housing. I kinda laughed and said none but he didn't laugh. He has a kid working for him that said it's supposed to be up to the check plug on the side. I'm not an excavator expert but I've never worked on one that's SUPPOSED to...

    Deere 655C - safety lever/machine travel malfunction

    I've got a customer with a Deere 655C track loader. I'm not real familiar with these machines, this is only the 2nd one I've worked on much. He was using it this afternoon and it came to a dead stop and the safety lever light lit up (like it does when the bar is down, in the parked position)...

    D7G keeps blowing torque converter output seal

    D7G 92V prefix. I had the torque out of this thing a few months back to replace the rear main seal that was letting engine oil transfer. Ever since then it has been blowing out the seal at the output yoke. I've replaced the seal 3 times and also replaced the yoke. I'm assuming I boogered...

    D6T running rough, now won't start. Thinking HEUI pump.

    Machine number KJL00898 Engine number THX14748 6700 hrs. For the past few months this dozer will throw a fit now and then and it would cough, blow white smoke, maybe die, maybe just almost die. But they'd shut it off, let it sit for a few minutes and it'd be fine. Might run for another 40 hours...

    Hyundai Robex 200 hydraulic question

    Hyundai Robex 200LC. Machine number E1043413613 From what I've been told this is a grey market machine and parts are unavailable for it through our dealer. I'll try to describe this issue accurately. No matter what hydraulic function you use, the hydraulics will run at full speed for about...

    End dump spewing oil

    Good customer of mine has an end dump trailer he pulls to haul material to his concrete plant. He uses it everyday but once the outside temperature gets below 40 degrees F it blows oil out of the vent cap on the tank when he lets the bed down. It's got a tank mounted right behind the cab and it...

    Source for running 3204DI replacement in a 926E??

    926E 94Z02469 3204DI 45V75771 ARR# 7C0934 As usual I'm working on a loader that just gets used now and then, so the owner obviously isn't real excited about going with a $10k long block from Cat. I googled "used 3204" but didn't come up with much. I use Vanderhaags for used truck stuff...

    Any Cat guys ever seen this happen?

    So one of my customers has put both his D6D's up for sale but wanted me to go over them before he started advertising them. I found chunks in the left hand final of this one so we tore it down. The inner side of the bull gear hub broke totally off.

    Proper operating temps of D7G?

    Got a head scratcher. Customers 7G (92V) is running hot. I'm talking it'll get clear into the red just tracking down a road. We've replaced the thermostat, and water pump. We've removed the radiator and had it professionally cleaned. I've disassembled the heat exchangers and cleaned them. I've...

    F1 Repair work and carnage pics.

    I don't take a whole lot of pics of my work but I always make sure and get pics of damage. Lol. So I figured I'd start a thread of stuff I've seen/fixed/MacGyver'd back together.

    Fiat 10b liner installation

    A customer up the road calls me up and wants me to come look at the engine in their 10b. It blew the head gasket and come to find out they had put one in it about 30 hrs prior to this one failing. So I immediately thought they didn't get something clean or didn't torque it. So I go up there...

    Final drive work on D7G, couple questions

    Tore this 7G down for a customer. Finally got to use the press and tooling I picked up! Customer says it's never leaked oil but he checked it the other day and it was low. 8 gallons later it was full and the book says it holds 9. Lol. And it leaked that out almost overnight. So he had me take it...

    Komatsu guys - PC300LC-3, coolant in oil.

    Wondering where to start on this old girl. It has antifreeze the oil now, about 2 gallons near as I can tell. Water pump? Liner? Head gasket? There's not alot of Kom stuff around here and most everything has Cummins power. This one is all Kom counterweight to bucket. Any pointers appreciated.

    Caterpillar diagnostic code book?

    Just curious if there's anywhere I can download a list of the fault codes for a D6T. I've got ET and all that fun stuff but it'd be super handy to have a hard copy cheat sheet in front of me when I'm on the phone with an operator reading me codes. Thanks in advance.

    In search of a 4bt block.

    Like the title says I'm in search of a good 4bt block for a 99 lull telehandler I'm working on. I really only need the block but I'd consider a short block or long block depending on price and if there's any history with it. PM me. Thanks, Sean. Sent from my SPH-L710 using Tapatalk 2

    Like the title says, anyone have a lead on a used straight blade for a D6T LGP? They seem to be sparse. Sent from my SPH-L710 using Tapatalk 2
