Thirty Five Gas

blwatson

From the ACMOC Serial Number Reference Manual, 5C1 was built in 1932. The last gas THIRTY FIVE was 5C 1730 one of only 10 built in 1935. Yours would have been built in late 1934. I am not sure if the pictures you sent were recent, but hopefully, you have intentions to bring it back to working order. There are not many of these left since only 1730 were ever built. Best of luck with it.

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 I believe this explains why several gas models were produced for several years after the technology was outdated in low numbers.
