[QUOTE="Philngruvy, post: 4694, member: 632"] Well-----------, You wont believe it!!!!!!!! I finally got my sorry rearend out back to work on the Bobcat. I took the two topmost covers off the timing belt for a looksee. Everything looked good, belt not broken, teeth all in good shape (both the pulley and the belt). So I marked the belt and adjacent tooth on the pulley and had my daughter bump the engine over slowly, so I could check the entire belt. We made about three complete revolutions of very short 1/2 sec. bursts. Son of a gun, on the next bump, the doggone thing started up and my jaw hit the deck. I do not have an explanation for it! I worked the machine moderately for about an hour with frequent stops and starts with NO problems! Now I am faced with the knowledge that the service on the belt is 1600 hrs. and I am at 1684 hrs. Do I tear it down and put a new belt in or keep running it? I am concerned about the information that the Bobcat service manager gave me about the engine being an interference engine. Is it really an interference engine or was he blowing smoke? If it really is an interference engine, how long do the timing belts really last before you have problems? Oh, and by the way, Thanks to all you guys who helped me troubleshooting this problem. It has helped me greatly in learning more about my Bobcat, and about the difference in $$$$ between Bobcat parts and the exact same part at an autoparts store. Ron [/QUOTE]
