Hey, I was just for the first-time this morning watching the Rick Stiver's videos and guess what ! _ _ _ he uses a sealed-bearing on the input shaft. The work never ends right ! Len |

I used Novak's T90 rebuild kit on the transmission I just finished. The kit came with a sealed bearing. It seems fine to me.

Oh, I'm all about the sealed bearing ... (at the obvious risk of jinxing everything ) The T90/D18 I rebuilt and am currently running have not leaked, seeped, weeped, dripped or discharged a drop. Both were rebuilt pre Stivers vids, and possibly metalshapers (though I so love his method of assembling the syncro hub, lol)...
The one thing I cannot figure out is why Rick reinstalled the oil slinger at the front with the sealed bearing. Seems like delivering oil to the back of the sealed bearing is daring it to leak between the inner race and main gear/shaft, or the outer race and the case, all without any benefit to the bearing...

So this got sidelined a little bit... lotta wood stove days lately . My work space is just a wee bit uncomfortable most days.
. . I'm guessing the paint is cured out Finally got a warm enough day to justify no stove, and my assembly lube wasn't a liquid ... but roadblocked again. My reverse idler gear bushing was just a little loose, I had a spare bushing, so I swapped it out. Now I sit waiting on a reamer . . ...and on to the next victim . . always, always, always open an inspect used parts to the fullest extent possible, lesson learned. This pto operated smoothly on the bench. Opening it revealed stuck roller bearings with the inner races acting as bushings as the shafts spun in them, the chain stretched to borderline (just starting to chew into the case) and the seals rock hard... . . . . spent a couple hours sourcing new bearings and seals, going to strip paint and finish cleaning it up today, then wait for parts ... Time to take the winch apart

Great progress.
I have the same PTO controller with a stretched chain that is eating into the case. I have been meaning to look into replacing the chain but got sidetracked with other things. Do you know what type of chain it is for replacement? No reason not to piggy back off of someone else's research.

I believe it's standard #50 roller chain... I know it's a #50 chain, some of the links say "50" on them and the dimensions fit, I just have to verify it's not heavy duty "50H" with the thicker side plates (and twice the capacity). I haven't found a dimension for the side plate thicknesses yet, and plan to swing by tractor supply to verify it. FWIW, TS is the cheapest plf I've found for #50... trouble is I have to buy a ten foot piece ... by the time I go through Mcmaster Carr or similar to buy 2-3 feet and pay shipping they're close enough that the convenience of TS is worth an extra couple bucks and 7-8 feet I don't need, lol. In short, if I go that route I'll send you a piece ;)
ETA: for folks that may come along after, The #50 Roller chain at TS is a match for what came out of my PT1-J (It does say "CHINA" on it, you'll make your own call on that )

I've always marveled at what these little machines could accomplish via a small hunk of chain.....
Very cool!

I wasn't expecting printed circuits inside, but the simplicity of this pto is only a step or two above a stick with a string wrapped around it ... K.I.S.S.

The reamer showed up for my reverse idler, the ORIGINAL T90 for my 69750 is "in the can" as they say. Seals, bearings and chain for the pto showed up,the large parts are cleaned, squared and threads chased. Tomorrow some small parts to clean up, the lever to paint, and we're on to the winch...or the heater...or the front axle, or the-

Looks great. Did you get a full face front gasket for the T90?

I'm a LOOOoooong way away from that gasket (the significance of this T90 is that it is the first piece of my 69750 parallel rebuild )

Oof... tough weekend
First i find the spring has popped off one of the seals for the pto... and fortunately it's in behind a pressed in bearing Best part? Access from either side only 5/8" dia... 45 minutes playing "Operation" with dental tools to get that fool spring back on the seal... but a success is a success... you can't always pick'em The seal corrected I turn back to assembling the pto. Once dry fit everything, then reassemble with gasket shellac, bearing mount, grease etc. I get maybe five minutes in and realize the main shaft is bent ...really bent. Didn't notice it before because I was pissed to find the bearings frozen, and the seals gone...the chain stretched. All in the past. Work the problem. Can't run it between centers, so I set a bearing and center the gear... the bearing surface at the gear is running good, the face of the gear is 90*... the shaft at the next bearing surface runs out 2 thousandths. I'll take that. The end of the shaft where the sprocket fits the spline runs out 70+... No way this works with a tight chain without rumbling itself. Two hours of setting it up in the press, estimating how far to go to get a little yield without going too far, take it back downstairs set it back up in the lathe, measure, mark high spots, back out in the garage, press, measure, press.... success is taken at it running 6-8 out... I'm adding new shaft to my want list, but this will run for now. . . . I spent most of the morning straightening my shaft, and finished up by polishing my knob Don't tell my wife
