Message: <blockquote data-quote="M600-Des" data-source="post: 61303" data-attributes="member: 8274"><p>Hi All, I'm looking for some diagnostic help with my Bobcat M600P's drive system. Symptoms: Engine runs well with the variable drive lever pulled right back (Neutral?) but when the lever is moved very slowly forward the drive suddenly engages and the engine revs drop and the engine labours very hard. If left like that the engine finally stalls. Pulling the variable speed lever back allows the engine to recover. Moving the steering levers while the drive is engaged and the engine is labouring makes the machine move backward or forward as expected. Leaving them centralised the machine doesn't move. Background: The machine has been standing unused (engine dead) for about 2 years. The engine has recently been restored and is now working well. When the machine was first started (2 days ago) it could be driven forward and backwards with the variable speed lever pulled fully back. Any attempt to engage the variable speed drive would result in engine stall. Yesterday, over a period of about 15 mins of use the maximum speed forward or backwards slowly reduced until the machine would no longer go either backwards or forwards. Engaging the variable speed drive made the engine work a little harder but it no longer stalled. Last night the machine was working well and there were no obvious signs of distress. Today, with the variable speed lever pulled right back the machine will not move backward or forward but when the variable lever is moved forward the engine labours very hard and will eventually stall. Actions taken: I have taken the right-hand drive cover off and was amazed at the immaculate condition of the housing, chains, drives etc. The oil looked brand new. As the machine is jacked up and has no wheels on the right-hand side I used a lever to turn the front wheel. This was quite hard to do but was smooth. There was a sucking, squelching sound from the oil which sounded more like grease than oil. It's minus 10c here today so maybe the oil viscosity is too thick? Moving the right-hand steering lever forward slightly while turning the wheel instantly locked the wheel solid. So based on my experience so far what is the most likely cause of my problem? Is it that the oil is too thick or could the problem be in the unchecked left-hand side? As an aside, am I correct in thinking that the two chain housings are connected? I can only find reference to one oil filler "telltale" and that's on the left-hand side. If not how much oil should be in the right-hand casing? If I have left out some vital information please ask away! Thanks, Des</p></blockquote><p></p>
