I just got done making a new pump drive setup on my 3414.

As to your's - it all depends on the serial number and which pump it has.

Early 3414 has a pump with a round shaft and single key.

Later 3414 has a 7/8" X 13 splined shaft just like many Deere, Fords, Cases, etc. use.

On mine - the pump had the 7/8" X 13 splined shaft. Then a 7/8" X 13 splined coupler that you can buy on this Website as a Ford part.

From that coupler - the shaft is 7/8" X 13 splined on one end - BUT tapers down and is only 3/4" splined on the other where it connnects to the drive plate on the crank-pulley.

If your coupler is bad, it's likely the shaft and drive-plate on the crank pulley is also bad. I adapted all new parts that I bought here. All for a Ford loader. New rubber-cushioned drive plate with a 7/8" X 13 hole instead of 3/4". New 7/8" splined shaft, new 7/8" splined coupler.

If ALL you want is a coupler - you can buy here under Ford. 7/8" X 13 internal splines.

No need to pull the radiator. Front pump MUST come out. In my situation - I had a brand new pump ready to go in anyway. I was just looking for an excuse. The original Cessna pump was completely worn out. I put a new Webster-Danfoss in (direct Cessna replacement).

My drive was still working but the backhoe would barely work once hot. Strangely - the front loader still seemed to work. I finally pulled out the front pump and it was completely worn out. NO way to fix. I also found the pump drive was just ready to stop turning. It was all hanging by a thread and all splines were hammered something awful. Note that this machine had been run for years with the hydraulic filter missing. That seems to be common with 3414s.

I had to pull off the front weights, grille, and then the front pump. Easy job. The hardest part of the whole deal was making an adapter plate to make a Ford pump-drive plate to the IH crank-pulley. I made a round plate from 5/16" steel and drilled holes to match the crank pulley and the new Ford hub. It's nice now that all the parts are standard and available here cheap.

When all done with the new drive, pump, hydraulic oil and new NAPA filter in the tank - it digs like a new machine. I'm amazed at the difference. I also put in a new PS/swing pump that I got from a place in England.
