My first backhoe for helping me out with general clearing and cleanup of a cabin site in Michigan. I bought this old worker with no illusions and understanding a 40 year old TLB machine will need some attention. I have fooled around with old cars and trucks for 25 years so it appeals to me to have an older fairly straightforward machine. It sits next to an old Allis Chalmers 1960 D-14 loader tractor that really does some chores for me.
The good news.... It is clean, has been well maintained, starts right up and runs smooth with no load and works well. The bad news.... the old gas engine is tired and smokes, consuming about a quart every 3-4 full work sessions and when put under any load (even moving from a stop in gear) I really have to goose the rpm's to allow the engine to "catch up" and then sort of over throttle to compensate. This is both the movement of the machine and/or the use of the hoe. Any up hill drive and she is sure to bog and stall if I do not really get the revs up.
When I bought the machine I used it a bit and had soem of the power issue but not nearly as bad. I stored and parked it all winter. In the spring I found the governor pivot arm was almost froze solid in place and took me a while with the PB and some tapping to free it up to get throttle control back but the under load loss of power is worse. I nurse it and nudge the throttle up and ease into work to get it done and allow the engine to bog but not stall usually. I have no experience with a governor other than what I have done to free up the pivot a bit. Besides doing a compression check next weekend and sorting out the issue of worn rings/valves and some engine work in the future, is the governor operation suspect in some of this bogging down under load? I would like to work it through this season if I can.
Can anyone explain how that governor is designed to work. Does a load on the tractor relate to the governor responding with increase revs? One of the old timers in the cafe told me that the early Case engine governor set up is the most mickey mouse engineered deal he has seen and they were prone to problems with linkage and freezing up with lack of use. I guess if I knew what is supposed to happen then I could
help troubleshoot a bit. Appreciate your experience and input. Ralph
