763 Creeping while starting

[IamNonStop]

763C the left side creeps forward or backward while trying to start, but only when it's cold. After it warms up, I can turn it off and back on without problem. Today I noticed the right side did it as well. It bogs the engine and makes it hard to start. I have to grab the controls and counter-act to keep the load off and let the engine run. Very annoying... thanks for any help.

You need to adjust your steering levers so they are centered. Its sounds like one or both are just a little bit out of center causing it to creep until it takes up the slack in the drive chain and hangs up on the brake. Sorry, I have no idea how to center the steering on a 763.

Would this be the case if sometimes it creeps forward and sometimes backwards? And why does it only do it on initial start up? After running a while, I can cut it off and then back on with no problem. And it doesn't creep while running at all.
My buddy said it is because the hydraulics are cold. I'm calling bs on that.
Any one with similar problems?

My 742 will absolutely creep a LOT more cold than after the hydraulics are warm. Find the neutral spot and hold it w/ your knee when starting. Another thing is the centering spring. The OE ones were near the same ID as the bolt and get gummed up w/ grease and dirt. A bigger ID replacement spring and cupped washer works much more freely in both directions. Abt $15 from Bobcat.

Thanks for the input. The reason I say my issue isn't because they hydraulics are cold, is because as soon as the machine fires up, the creeping stops. It doesn't have time to warm up at all before the problem stops.
I will look in to the parts you mentioned, but I can't hold the control in neutral with my knee because when it creeps forward I pull back but then within a second it starts creeping backward. I keep having to push/pull the lever while it's cranking so it doesn't strain the engine and it will fire.
Also, if it helps in diagnostics, the lever jumps and the pump makes the growling sound. I'm guessing this is because it is pressing against the brake.
Any more help would be great.

My machine self feeds the stick just like you describe if I don't hold it in place with my knee. Unless it is in really tight quarters I release the brake before attempting to start the motor. Takes lots of that pump load off of the starter that way. Dick

I usually hold the left lever with my right hand to correct the creeping as I turn the key with my left hand. I can't use my knee because sometimes it creeps forward and sometimes backward.
Anyone else know what I can look at?
I really don't want to take it to the dealer...

You will most likely need to replace the worn lever cams on the steering control valve, mine were way worst then what you mentioned, actually my bobcat was almost dangerous to use it was so bad, there are many posts here in the forum about creep, and how to fix it, I ended up taking mine to the bobcat mechanic/ dealer to fix, and it is very stable now, I believe they also replaced all the steering bushings too.

The steering bushings have been replaced about a year ago, so I will look into the steering control valve cam. I just ordered a manual (didn't have one) and hopefully can narrow down the part and fix myself.
Thanks!
