eed parts for 1969 Dynahoe Backhoe model 140 This time U Joint the whole unit
I know this is a 2018 thread and hope by now you have sold your Ujoint problem. If not you might want to try Fleetpride in AZ. ~ Orangeman
OK my bad, so not a 2018 thread - sold above is solved.
U joints on nearly anything, but most especially a dynahoe, are a universal part that you usually can find by measuring it up.
The U joints are likely a truck driveline part that was available at the time the Dynahoe was built so am recommending looking at 69/70 truck axle and driveline parts listings. There are a number of good truck parts places throughout the country - Fleetpride is one and so is Cook Brothers. When Hough (read Hy-Dynamic) began building Dynahoe backhoes most of the parts were truck parts. Bucyrus Erie acquired HyDynamic Dynahoe Backhoes are were marketed as 140B, 160B and 190B machines. The 140 was very similar to the earlier letter machines - particularly the Dynahoe Model C Backhoe.
