Put on your thinking caps!

A Lovejoy coupling would run quieter and smoother. Do you have room for it? The old chain type couplers are still available too, most industrial power transmission suppliers should be able to find one.

A ton of threads/discussions on converting non-driven machines to driven machines. Discussion varied from belting a pump up to mounting it on the front with a specail adapter made up with a piece of 3-braid hydraulic hose for the power transmitter. I read them, studied it, determined the easiest would be to find a machine in someone's junk pile with what you want and buy it. Like I know a guy in Minnesota that has a BE-GE front mounted pump on his parts tractor which someday, I hope to buy. (someday as money is tight)
Mine is mounted on the back and truthfully if you think two steps ahead when operating it, then it is not a major handicap. I vary rarely need to shift to nuetral, then re-engage the clutch to get the blade up in the air. I would only change it to install a PTO shaft on the back for pulling farm related equipment.
👍

As far as couplings go, the major factor in how well they hold up is in how well they're aligned. If there's much more misalignment between the two shafts than a few thousands of an inch in any direction, the coupling chain is gonna wear out before long. Another factor is how dirty the area is that the coupling is going to function in. Open chain couplings are good but if you can find one the proper size that's sealed for dusty/dirty use it's going to last longer.

The original LC drive shafts were pretty elaborate. I've seen replacements as simple as a solid square drive shaft with square internal hubs on the ends.

There was a thread about this back in 2008- "Front Hyd Pump" here is a quote-

"If you need to replace the almost obsolete 'single-double' coupler chain the Link-Belt part number is ARC 5016. You will need to cut a link out.
Modern double roller chain will not fit between the pump and radiator."

Funny side note if you search the web for that part number you mostly get results from ACMOC threads 😊

When you say "cut a link out" you scare me a little. I asssume you have to shorten it by one link? How about connector links,half links etc.The old ones must have been installed by some supreme being, because there are no visible connectors. Do you know if they have the sprockets as well?

It was a long time ago 😊 I think the chain came with a master link. To shorten it I think I just ground off the head and drove the pin out. The reason there is no master link on the old one may be that the coupling came as an assembly, and was installed on the shafts, that is, the chain did not need to come apart.

Sorry I don't know about the sprockets

That makes sense. I think I will order one and see what I get. I have spent much more on a lot less. I think I can get weld on spokets at the local farm supply store if needed. Thanks for the advise.
