Any one ever rebuild an instant reverse transmission?

Danielfire50 · Dec 17, 2017

I was comparing the new clutch plates with
the old ones. The old steel plates have a
definite dish but the new ones do not. Is
this going to be an issue or not?

Been a long time ago at the MF dealer I worked for. If I recall both drive and separator plates should be flat.

Dished, or warped steels are junk on just about any kind of "automatic" type transmissions.

I'd be interested in how you make out with it. My 205 wants to creep forward all the time and I have to bump the pedal to reverse to shift it. I think the plates are probably warped.

Danielfire50 · Dec 17, 2017

According to the service manual the originals are dished. It only mentions that the dish of the plates should all face the same direction.

Dieseltech · Dec 17, 2017

By golly sir, you are RIGHT! I just checked the revers-o-matic book I have, they show to check each disc on a flat surface with the dish UP. The INSIDE clearance should be more than .005 inch, if not replace. New disc is .015-.018, also says on assembly have them all the same direction. Told you it's been a long time! LOL

Interesting that the originals are dished, I wonder what the reason is behind that idea.

Dieseltech · Dec 18, 2017

I'm thinking they had a slight dish to help the clutch apply a bit smoother as the discs flattened out under pressure. Been years since I had one apart.

Danielfire50 · Dec 18, 2017

I'm guessing they may be dished to insure
they fully release when disengaged.

Danielfire50 · Dec 18, 2017

Ya I guess it would probably make for smoother engagement.

Danielfire50 · Dec 18, 2017

Well I guess i will find out how the new plates work when the rest of the parts come in and I can get it back together. Thanks for all your thoughts on this.

How much of a nightmare was getting the trans out? I think my forward seal is bad, leaks hydro fluid a lot.

Danielfire50 · Dec 18, 2017

Not real easy but not terrible. No worse
than splitting for a regular manual
clutch. Ideally your gonna want a nice
flat slab to do the split on. I didn't
have that so I made a track and trolley
contraption. Your also going to need to
make some guides out of some 6" bolts. Cut
the heads off and round the tip over.
Replace some of the bell housing bolts
with the guide bolts so everything stays
lined up during first four inches of the
spilt. Otherwise it will ruin the pump.

Seems like if the slightly dished plates made it apply a lot smoother, or whatever that they would be using them in cars, and trucks. Still interesting though.

sound like they are heat warped any clutch pack i have worked on the plates are all flat

Danielfire50 · Dec 29, 2017

Well I just finished putting the transmission back together and back on the engine. So far so good. It appears to work but I haven't load tested it yet. I still have to finish reassembling the FEL and body before further testing. It was a bit nerve racking getting the transmission lined up even with the guide rods but it eventually went together with minor adjustments and moving the flywheel.

ptfarmer · Dec 29, 2017

Sounds about normal putting it back together, so it works (so far) with the new flat plates instead of the old cupped ones?

Danielfire50 · Dec 30, 2017

So far but that is only spinning one of
the wheels in the air. I still more
assembly before I can drive it.

Danielfire50 · Dec 30, 2017

Yes I used the new flat plates.

ptfarmer · Dec 30, 2017

The one wheel spinning while its in the air is the differential is working, your tractor may have another pedal to lock the differential as needed.

Danielfire50 · Dec 30, 2017

I know. I jacked up one wheel to see if
the transmission was engaging at all. I
was worried about the small sealing rings
on the oil supply tube of the input shaft.
They didn't go together easy.

That's why I'm glad my 1965 MF2135 industrial is a manual shuttle with a clutch. I bought a 1971 Ford 4500 TLB with the instant reverse/torque converter deal, I swapped it out for a regular Ford 6x2 manual transmission with a clutch. For what I'm going to use it for on the farm I really don't need the instant reverse/torque converter setup. The Ford instant reverse also doesn't handle/like heat too much so I'd figure I'd kill a lot birds with one stone.

Danielfire50 · Dec 31, 2017

I understand that. After buying most of
parts for transmission I think I could
have converted it to manual cheaper or at
least about the same price.

Any one ever rebuild an instant reverse transmission?
