My 743 5019 serial number unit front cylinder is leaking a little and I called the Bobcat dealer here in Middle Tennessee and ordered a rebuild kit. I also have the service manual and for that repair it says I need the component repair manual and does not detail the repair procedure. I have never rebuilt anything like this before and I am woindering if I would be better off taking the cylinder off driving it to the dealer and let them install the rebuild kit. Any advice would be appreciated. Also Kudos to Tazza he coached me through fixing an oil leak that was rooted in my throttle coonnector plate on the top of my 743 Kubota engine. Ir cost around 50 bucks in parts but it saved me the hassle of taking the machine to the dealer. Again kudos to Tazza I really appreciate it!!
