First Job Out With The Bobcat T770 And We Have A Major Issue!!

- I loaded the T770 up and moved it to my dirt pile to load my truck. All went well (other than me dumping dirt on the machine the first scoop) and it seemed to have lots of power and was really quick on it's feet. However, I noticed while watching the video back it was smoking terribly bad under load, I mean like Cat D9 bad!! Sooo, I now have to figure out whats going on with it before it washes a cylinder out (hopefully it hasn't yet).
I done some research on it creeping on an incline and found that to be nomal. Once I engaged the parking brake it stopped. The over fueling though has me puzzled and nervous! 😲🤦♂️
if nobody has told you yet, there should be an automatic bucket position switch at #3 on the left panel which will keep it level when you raise and lower the arms. looks like you have it in the off position for this video
Lol....I figured that out eventually. It works great now. Thanks!
Glad you got it Larry. Glad you are fixing it up and painting it. Have a great day.
Thanks, you too!
On my older Bobcats there are no brakes just a traction lock solenoid. Take power off of the solenoid and the plunger drops on a cog that stops the machine. The steering levers use a metal block and need to be adjusted and the rollers often wear flat spots.
Yeah, after some research I figured out that the creep is normal. When I raise the lap bar it stops. It’s just a different critter than what I’m used to. Lots of learning to do on this one.😁. Thanks bud!
You got this one Larry. Good luck !
Lol, thanks! Just need some seat time. I’ll get her figured out.
having the bobcat will open up a lot more oppertunities for you work wise
I hope so. Thanks buddy!
Lol, you look like I did early on in my skidsteer career. I couldn't grade a flat surface, I dumped dirt in my own lap, and that thing almost beat me to a pulp.
I watched a guy operate one and thought, that looks easy, I can do that. I didn't understand he'd been doing it for 10k hours and had a lot of skill. It took me a while to learn that a skidsteer didn't operate like anything i was used to running. In a few hours, you'll be smooth as butter.
Lol! Yeah, just gotta get some seat time and I think I’ll be ok. I got the owners manual out and read it front to back. There’s a bucket leveling switch I can flip and it’ll keep the bucket flat as I’m loading with it. Who knew….lol!🤷♂️
Gonna be a nice machine when you get all your bugs out great video buddy 👍
I hope so, thanks Willard!
YES - *ANYONE with a BOBCAT with answers for DIRT DADDY* please chime in. My main concern would be all that SMOKE (I know it might be old enough but man!) *DD* you did well with what you showed us and after all, your experience is in much bigger toys. Really hope you get all the wrinkles ironed out CHEAPLY! Thanks!
Hey Sonny!
Everyone has been really helpful with suggestions on these issues. It's just going to take some time in the seat. I'll get her down pat eventually. I hope I can get her fixed up where it's going to be dependable and not break the bank! Thanks buddy!
@@Dirtdaddy953 *TH-cam is GREAT* for gathering PEOPLE we'll never meet but I love how strangers can *REACH OUT* to help out the other guy! Thanks to *ALL THOSE WHO POURED OUT TO Y O U in a short few hours* ! Nice!
Nice t770. All bobcats creep back until you set the parking brake. Lifting the seat lap bar will set them also. On the left hand upper corner close to the green operate button you will see i switch that keeps the bucket flat whiles loading a truck. Be careful though because that is more suitable for keeping pallet forks level rather than a bucket heaped up with dirt lol. The hydr temps are a little concerning. Might just be a filter or the oil needs to be changed. The smoke might just be the air filters needs to change. Machine seems to be nice and it sounds good. Best of luck!
Yeah after some research I figured out the creep is normal. Lift the lap bar and it stops. I took the operators manual home and read it and found the section on that switch and what it does.🤦♂️ I flipped the switch and she goes up nice and level. Thanks bud!
On the oil temps. I already changed the oil and filters. I thought I had the radiator clean when I was doing the maintenance. But I later lifted up the condenser and took an air hose and blew through it again and got a lot of crap out of it. I’ve used it since spreading gravel and it was a lot better. But wasn’t working it all that hard. Time will tell I guess.👍
I'd run it at half throttle till you get used to the controls and a tip i was given with a hand control machine was to hold the joy sticks as close to the bottom as you can till you get used to the controls not as touchy when working the joysitcks from the bottom part I prefer a foot control machine my self but can make do with a hand control you should get a bucket with teeth for digging it makes it easier for digging
Exactly. I’m with you 100%. Hand foot controls is where it’s at. Way more controlling, good feedback, and zero hesitation. But yeah hold at the bottom of the sticks It makes it way less jerky and jumpy. I use the foot throttle on them to govern the speed to help control it. That’s one reason I hate electric controls on a skid steer. Way to much bouncing to keep a steady hand. Once it starts bouncing you gotta let go because it will keep doing it. Which hand placement helps a lot.
Yeah, i just need to get some seat time in the little sucker.😂 I’ve gotten much smoother with it since this video. But it’s going to take some time. It’s my first one so in the mean time I get to make comedy videos of me running it until I get more proficient.😂😂. Thanks buddy!
@@Dirtdaddy953 yeah it’s like anything, takes a little seat time for a true operator. Others make take way longer or never get it. But you’ll
Have it dialed in no time. 😉
Oh boy! I loaded my truck with a foot control Bobcat as I mentioned in the video and hated it. Kudos to you guys that can run those things smooth! I suppose with some seat time I could get used to it, but it was hilarious to watch. I made a video of it a couple years ago.😂😂
Yeah, that’s the plan to get a toothed bucket…especially in our area. The cutting edge on this bucket has to be cut off and replaced so I can put the bolt on edge that I bought in it. Thanks!
Yep! Just takes some time.
I think you have yourself a nice machine sir. Looks like you have plenty of power and appears to be pretty stable. On the hydraulic temp gage, it might be a sensor issue or even the gage itself, I have seen this type of issue before, have even seen cracked spool valves cause heating issues due oil bypassing thru to another chamber, a restriction in a line might do it to, just some thoughts young man. Thanks for the tag along video, enjoyed watching and I remember the first Bobcat loading monkey business, and here to tell you, you still did well compared to what I would have done!😊😂😂😂😂
Thanks terry! Yeah there’s no telling what it could be. I’m gonna keep an eye on it.
It seems to be a good machine but I have a lot of bugs to work out. It wasn’t taken care of and now I’m having to deal with it. Thanks buddy!
The smoke is probably dirty injectors not atomizing the fuel properly. Run some Power Service Diesel Kleen through the tank. You can get some at walmart. Also keep a fire extinguisher on hand at all times, preferably a Clean Agent type that wont cause much damage if you have to use it. All it takes is an old hose to rupture and spew oil everywhere and burn down the machine.
Yeah, with my luck it wont be that simple. Lol, I try to keep them around but I guess that's what insurance is for. Thanks bud!
Few things... You have a hydraulic motor screaming... Second, they creep on a steep hill. If you keep a tiny bit of pressure on the drive joystick, it will stay put. Third, there is a rocker switch inside with a yellow half that turns on the self leveling bucket.
Yeah, after some research I figured out they do creep some on a hill. When I lift the lap bar it’ll stay put. Lol, I got the operators manual out and read it. I flipped that switch and she stays nice and level when I raise the loader up.🤦♂️
As far as the hydraulic motor goes I’m not hearing anything abnormal or from one side of the machine or the other.🤷♂️ It seems to have plenty of power and isn’t doing anything weird (yet). I’m still trying to learn all the machine sounds so I’ll have to keep an eye (or ear) out and see what happens. I’m gonna put some hours on it with the new oil then I’ll pull an oil sample and see what it looks like. Thanks bud!
Hydraulics are fine that's how they sound
Thanks!
On my bobcat when it gets hot and close to the red you should be able to hear the fan like kick into high to help cool it better. That’s when I stop to let the temp come back down. But it shouldn’t do that just loading a truck. I’m in Texas 110 degrees and gotta work it hard to make it do that.
Hey Cody!
Not sure I've heard the fan speed up, never really paid attention I guess. The fan seems to be moving a lot of air as you can really feel the wind coming out of both side louvers. I pulled the condenser back out and blew about 175psi of air through the radiator and a bunch of crap came out even though I'd washed it out with a hose. We'll see I guess. Thanks for the input!
They all creep. Parking brake or lift the lap bar to make it stop. If your not making it drive then it’s technically in neutral. The parking brake is just a pin that pops out and locks the drive gear. So there isn’t any real brakes on them. This is with the bobcats. Others I’m not 100% sure about because I’m bias to bobcat and their hand/foot controls.
I was worried until I done some research, but like you said it’s normal. It’s a new critter to me so I’ll have some growing pains. Thanks Erik!
Did you have to replace and reprogram injectors because of the smoke?
Yes, I pulled the injectors and took them to a pump/injector shop to be tested. Two failed, and the other two were borderline. So I bought new ones, slapped them in and took it to Bobcat to be programmed. All is good now!
The smoke isn't normal. Seems down on power too. Should be spinning the tracks into the pile before bogging out the machine like that.
Yeah, it’s definitely not right. I’m putting a lot of down force with the loader while filling the bucket, so I’m not sure it would spin the tracks as that dirt was hard. I’ll get’er figured out eventually. Thanks!
Not sure if you changed your chain case filter bobcat doesn't mention in their service intervals log. But if you haven't im going to possibly save you thousands of dollars. Its under your cab on return line from final drives. Some have two filters one for each final that is the best set up so if one final goes it dosnt destroy the other! If not you can get aftermarket bypass to add another filter!
Would a rubber tracked loader have those filters beings that it doesn't have chains?
Yes sir. When you pop the cab up you should see return lines from finals they come together into a small silver canister with a internal filter.
Thanks, i'll have a look when I raise the cab next. I have a "hydraulic lock short to ground" code that'll come up every now and then. So I need to look on the control valve and see which solenoid I have so I can order a new one.
Right good luck! Keep the videos coming
Will do, thanks!
Video on TH-cam on how to adjust sensitivity sjc controls
Thanks!
They all creap back
Unless you put the parking brake on or lift the seat bar
He is spot on his answer
Yeah that’s what I’ve figured out through some research. My 953 doesn’t so I was a little worried. But two totally different animals. Thanks Lucas!
Yes, it stopped after I did that.
Yep!
Probably injector going bad
Yeah, you'd think they would last longer than 2500 hours though. I'll get it figured out im sure. Thanks!
