RockingJFarms Posted July 5, 2023 Share Posted July 5, 2023 Hey everybody. I have a 68 r685 with a 237 and five speed. The truck currently has a pto on the transmission but no wet kit. I'm looking to add one to pull my dump trailer around. The problem is thought that the pto has a 1 1/2" keyed shaft, unlike modern ptos which have a female end for the shaft from the pump to slide into. My understanding from research is this is an old style using a jack shaft to run from the pto to the pump. Has anybody added a pump to this style of pto recently? I'd prefer to keep the current pto and retrofit something to it instead of replacing it.

1961H67 Posted July 5, 2023 Share Posted July 5, 2023 Yes , I put one on my H Model when I installed a Rollback bed, I just hung the pump from a cross member ( made a mounting bracket) ran a pto shaft with a slip joint from PTO to Pump , we also have a B Model dump with the same setup. I’m sure all the older trucks were the same setup. I don’t think the Pumps were mounted to the PTOs until the early 80s , I have 3 later 80s Superliners and the pumps are mounted directly to the PTO .

mrsmackpaul Posted July 5, 2023 Share Posted July 5, 2023 Yep, my R model has a set up like you describe The bracket for the pump is very substantial I'll see if I can find a photo Paul Quote Link to comment https://www.bigmacktrucks.com/topic/73008-68-r685-adding-a-wet-kit/#findComment-534207 Share on other sites More sharing options...
