oliver hydra power

hi, i have an oliver 1600 and i would like to know if there is a way to eliminate the hydra power unit. it sounds like its on the verge of coming apart. i never really have or had a need for it to work. any ideas?

Offhand, you need the bellhousing, cover, shaft and coupler. By the time you factor in parts & labor, coupled with the opportunity cost of time spent tracking that stuff down, you could just rebuild the two speed if it's not something simple to begin with.

Also, I've known more than a few farmers whose two speeds turned themselves into a single speed and they ran them just fine.

Andy, I don t know where you live, but I have a hydra power I took out of a 1650 that s good. Only reason it s out is I put a three speed in. Live by LaCrosse WI. $500.00

This is a thought and only a thought. You said it sounds like it is on the verge of coming apart. Is there a chance the noise could be coming from the coupler chain and thats what youre hearing ? Just asking. That would be a much cheaper fix if thats all it is.

We had over 100 of them in our service area and they were good dependable units. As has been suggest look in the chain coupler area for mis alignment of the 2 sprockets. I offered to send you a head gasket trouble shooting chart but you must have solved that problem.

The sound could also be coming from the pressure plate, I remember pulling the clutch out on one of our 50 series tractors and the springs were so loose on the pressure plate they almost fell out. The tractor sounded like it had a handful of bolts rolling around in a dryer.

hello all, new day new problem. thanks for the input about the hydra power. on my oliver 1600 the pto doesn't stop turning. had it apart once and it worked right for awhile. it seem like maybe there aren't enough shims to keep the discs apart. when i push on the pto throw out bearing by hand, it locks in the pto shaft. when i spin the discs the pto shaft turns. so what do you think?

scootergmc · Mar 10, 2023

Does the PTO lever have good snap when you move it over center? Do you mean the pto shaft won't stop spinning without a load? If so, what happens when you have a load? Assuming everything is adjusted correctly, it's fairly normal to have a bit of clutch drag and the shaft may still spin without a load.

Chris Losey has a couple (here's the second) videos about your PTO clutch here: https://www.youtube.com/watch?v=oB3HZl5PcR0

hi,
yes, the shaft keeps spinning when not engaged, but its just fine when it is.

There are little compression springs in the plate between the clutches that are supposed to push things apart. No doubt broken at this age.

i worked on the pto a few years ago and replaced those little springs but i'll check them out again. funny thing with this tractor. it is clearly marked with decals that it is a 1650. i ordered a used pto shaft and it was too long by a few inches. come to find out from the oliver museum, by serial number it is actually a 1600.

Does it power an implement with the PTO disengaged? If it doesn't power the implement, I'd say you're ok for the time being.

andydap · Mar 11, 2023

no it doesn't, but i have it all apart now so i'll see what i can do.

Are the splines worn on the shaft where the PTO clutch plates slide on then? Are they tipping so they're wedging up?

andydap · Mar 11, 2023

no, the splines aren't that worn but found that one of the discs came apart and the unit that the bearing slides on is really worn so that the bearing itself has no play but it wobbles all over the place.

The PTO shaft turning is a common problem. Usually if the shaft has a bit of a load on it the turning will stop. My haybine holds the PTO stopped until engaged but my baler rolls even with the PTO handle disengaged. Makes me keep my shoes laces tied up.
