We have a 35 gas serial # 5C1663. I do not see much mentioned about them here. Can any one tell me how many were built? It has not run for some time but I did watch it do a lot of work when I was a kid.

Thanks so much for the info. I thought there must not have been too many made. We have been wanting to get it running again for some time. I have been working on my D4 7U here lately. Will be needing to make a decision what to do with the 35. I wanted to try and find out some info and history about it thinking it might help us decide which way to go.

The 35 gas was the same basic chassis as the 35 diesel. this was followed by the 40 gas and diesel which later became the RD6. The gas engines evolved from the two head thirty using the same crank and rods with increasing bore sizes. I had the privilege to look at some one of a kind CAT literature belonging the late Dave Smith. One was titled Selling the Caterpillar and was for the sales people only. Salesmen were instructed to sell farmers, contractors, and loggers diesel tractors and to market the cheaper gas models to municipalities. I believe this explains why several gas models were produced for several years after the technology was outdated in low numbers.

Thanks for the info Russell. My father and his mining partner used this cat on the mine from the early 1950's until the mid 1970's when a piston broke. It was parked at the mine until I had it hauled to town a couple of years ago. My father is no longer living and his mining partner is 86 and not in too good of health. I am hoping to find the time and parts to get it running again.
