A little mission creep: I have to drain the hydraulic fluid, so replacing the lift arm bearings and seals. Other deferred maintenance as well (fairly simple 'while the tools are out' stuff). I'd replace the cab floor cover, but it's NLA (and the TN75SA is a one piece that is not listed as compatible; not idea why not, I thought they were all the same cab). The loader joystick is likely the first version; the new boot is an oh well, it should work good enough (NLA for the 1st version).
A tedious process to find all the little seals and gaskets, but not terrible. It helped me realize the scope of the project (oh, yeah, if that is the hydraulic oil supply pipe of course I will have to drain it all...). After 25 years, I have zero hope that anything will seal once removed. Working with a dealer staff to resolve the gasket for the power steering pump to auxiliary/accessory drive case. The one for the main lift arm could be the same, but what I need is not shown. I can wait a few days while this resolves itself. FWIW, the power steering pump is a common Bosch/Rexroth used in bunches of equipment, can be had for quite a bit less than through NH.
Found a video removing the hydraulic filter assembly. The guy could have cleaned the work area up, but it does show I may not have to remove the loader bracket (or I may -- mine is an early version loader bracket; TBD). Just posting this for the sake of posterity. Also including a video. Nice to have pictures, regardless of how one might do it themselves. Will also post links to posts here on that. Call it a memory bank.
These posts have a range of ideas -- the simplest is spending a few dollars more for the endless type C clips/snap rings/circlips. Next is bending them while in place, avoiding chasing the thing to get an end out. I found a new bar for cheap, but they were out of stock. This is a common bar for a number of Fiat/Ford/NH tractors. As are the spherical bearings. I was unable to find that exact bearing number (the last few letters), but I decided that the SKF GE25C was close enough. The NH spares picture (online parts tool) showed a slightly different number. These were 2 for $50 vs 1/$82. Hard to argue that. The video was helpful to me to picture that all the wear parts are in the retainer cover (not including the wear surfaces on the shaft). That means you can take it to a bench to do the work. Plus needing buckets under the shaft ends. Hope this is helpful to someone else down the road as well.
TN75 4wd has started to have a hydraulic leak coming from the pivot point of one of the 3pt arms (where it attaches to the tractor). tried to attach a pic showing the fluid coming out. what is the culprit here and how big of a chore is to fix (is there a gasket that has failed on the...

Hi Gang, Since my 2005 TN75DA has made a hobby out of spewing hydraulic fluid all over my shop floor, the latest leak isn't too much of a surprise. I've isolated a static leak at the shaft/bearing that supports the lower 3 point hitch attachment (left side). As I looked at the Messicks...

Ok, so I'm stuck on stupid. You know the part on /in the rear axel that hooks to the lift arms for the 3 point so they go up and down.... What is that part called? Are the seals relatively easy to replace? My left side is leaking Thanks Sorry for my ignorance
