hello everyone. i thought i better introduce myself. i work for the caterpillar dealer in st louis but own a bobcat. go figgure. i bought a 743B last fall. it had a spun rod but i knew it up front. just got the engine back in and running today. i thought caterpillar yellow was high cost. i believe kubota grey has them beat. this is a very interesting forum with a load of good advise and ideas. if i can answer any caterpillar questions, let me know. i am a field tech and see a couple a week in the field. mikie.
