Just had a fun go around while replacing the trunnion bearings in the front axle of my long 610DT. Long story short the bearings and seals in the parts manual aren't the correct size for the axle housing and kingpins in the tractor. The long story with part numbers is below in case it helps anyone out. I still haven't sourced kingpins or kingpin shims that work, but my king pins were ok, and I ordered some 65mm ID x 80mm OD x .5mm thick round shims from McMaster Carr and I'll just notch them where the three bolts need to pass through. (McMaster - 3088A608 1008-1010 Carbon Steel Ring Shims, 0.5 mm Thick, 60 mm ID, Packs of 10)
Here's the rest of the info:
The kingpin bearing is TX52071 (#10 on the diagram). The parts manual lists it as a 30mm x 60mm x 21.25mm. As it turns out this is not correct. The actual bearing that fits the 610DT axle housing is 30.16 mm x 64.35mm x 21.43mm. I measured the housing and was able to source bearings for it. The tapered roller bearing part number that fits it is M86649 Cone and M86610 Race.
The original bearing that came out was actually a friction type, socket and cone with a plastic bushing in it. I traced that back to the following part numbers:
S.62487, TX51785, OSA206S, 05119699 Fiat, 64.29mm x 30mm x 21mm
The TX51785 number shows up in the index of my parts manual and shows it referencing page 259, but it's not actually listed there.
The Seal TX52072 (#9 on the diagram) comes back as a seal that is 58mm x 80mm x 10mm. This is unfortunately not the correct size either. The kingpin that it rides on has a 55mm shaft, not 58. So the proper size seal is a 55mm x 80mm x 10mm.
The original seal has been burned out by someone attempting to heat and remove the kingpins in the past so I wasn't able to retrieve numbers. But I was able to source a seal that worked:
SKF 562656, National 55x80x10-R2LS32-S, Garlock 25003-3429, S.50408 (Sparex), Grainger 53XN31 (MFR. 558010TC)
I know the kingpins are also hard to find for this tractor so I took some measurements on those as well. They are:
30mm small bore diameter, 55mm large diameter. 30mm dia is 20.5mm tall, the 55mm dia is 34.5mm tall (so overall height is 55mm). 13mm bolt holes.
