sorry guys got it all wrong it wont turn right you push the left lever foward and pull the right lever back and it struggles to turn to the right.it seems the wheels on the left dont want to turn,but if you only push the left lever foward by itself it will drive straight ahead.
its a hydro machine 343
Are you sure that is the correct model #? I can not find a 343. If it is a hydostatic machine it could be a motor or a pump. The easiest way I have found is remove the hose from the motor and cap off the hoses and the fittings on the motor. Start the machine and move that lever if it boggs the engine and tries to kill it the pump is good and it is probably the motor. If it does not bogg the engine down alot then it could be in the pump. Hope it helps. If your not sure of the model send me the serial # and I will see if I can figure it out.
What happens when you try to use that side? does it squeel, bog down, vibration in the stick, anything? I was thinking chain but you would need to snap 2 chains. The gear case should run 2 chains, one to the front one to the back for each side.

Sorry guys ,have trouble loading the full thread for some reason
I'm surprised the site allowed it to duplicate. I was going to delete the 2 additional posts but i don't want it to nuke the entire thread on you.... I'll leave that one for owensge, he knows what it will do.
Yeah Tazza ,swapped the motors over and still have the same problem on the left hand side.(Ive Jacked the Machine up and took the wheels off. the left hand side hardly moves at all).So it must be a pump problem on the left side of the pump. Any guesses what the problem may be inside as the right side of the pump is fine. The Pump is a Daikin PV1515-519 51-JD-17658.
There was no metal shaving seen in any oil. And drive chains are all good and intacted.
The only thing you can do is pull the pump and crack it open. I don't know anything about that brand of pump but it should be essentially the same as other variable displacement piston pumps. It could be a worn swash plate or the rotating group. I just wonder if it could be a simple as a stuck relief or poppet. These should be in the center of the pump where the hydro motor hoses connect up. Thats the last thing you could check before opening the pump up.
Ill check it out. its something that happened straight away it didnt come on gradually.maybe it might be that simple
I hope it is that simple, coming on so fast does seem like it could be something stuck than wear that would cause it to get weak then stop. It could get weak fast, as in a few hours work but i would doubt it would just stop from wear.
Hey tazza ,good news mate .started pulling out and found a broken roll pin in the main arm on the pump. ill put a new one in and keep you informed hopefully its just the one problem.
The shaft seems to turn freely as if all is well in side
