hydraulic pump coupler

andyinct. · Nov 6, 2012

I have a 3400 with a loader. The coupler on the front mounted pump - for the splined shaft and it has 4 bolts in it. The piece is worn. Are these available anywhere? Thanks

New Holland has them. It is best to replace the shaft and the hub at the same time because if one shows signs of wear the other is as bad. BTDT many times over the years.

Is it a Morflex coupler? That's what my 840 used and I purchased a new coupler and shaft from this site.
Morflex for 3400

On a 3400 if it has the Ford 730 series loader on it (component #s 19-417 / 19-419 / 19-523 - could be any one of the three) the part numbers are: 291315 (4) bolt hub that bolts to crank > C5NNN879A (4) bolt hub that slides onto the shaft > 292222 shaft 10.38" long. You will find the compnent # of your loader on the steel id plate left front inside of loader frame. These parts should be available through New Holland, but are also available aftermarket. Truth be known, the aftermarket parts might possibly be from the same manufacturer as oem. Hope this helps.
