mf 50c instant reverse linkage

[Sinned133]

can anyone tell me how the linkage is connected inside trans on a mf 50c instant reverse?

 

[damn1981]

Pin on outside goes to a fork on inside which hooks into control pin and moves spool up and down only way to service it is to split it

when i push on reverse I hear a whining noise no reverse takes off forward my tach doesn't work for any kind of pressure check when I changed fluid and filters it was really nasty but i was able to see pump working at the filter so I figure split and hope I can do this I'm a 1 man show

 

[damn1981]

Did you service screen on bottom cover
Is elongated and where sump for trans pump is
But if it moves forward probably reverse pack is toast can also check forward reverse pressure plungers on side of trans make sure spools are not stuck

Get a manual for trans do not have to pull transmission out once you have it split everything comes out front and idler gears and shafts come out the bottom they have to come out to pull clutch assembly lots of times rings are broken need to check manifold for wear when rings break it grooves it

I have a service manual, the screen is rectangle and it was more than 100% plugged before I put on filter I cranked until I had fluid coming out so I think pump is ok I have a strange feeling its the valve and clutch pack

 

[damn1981]

Were there any metal pieces or like pieces of clutch material when you had it off
There is also a filter inline to cooler or by cooler
Most people used reverse for brakes and it would tear the splines off the fiber discs
Don't know if they still make them but dont use paper discs

 

[Sinned133]

I don't think filter or screen were ever changed brakes are bad so I'm sure you are correct, I can get the rings and a rebuild/gasket kit so I think I can rebuild clutch pack just a little worried about shims and needle bearings

 

[damn1981]

Well if you need help doing anything or need hard parts let me know still have some contacts

 

[Sinned133]

I'm going to reach out quite a bit I'm sure, I decided to support the bucket high enough to split like you said, Just waiting on weather I hope to have it done by july 4th

started dismantling my MF-50c. So far, I have about 15 hrs. into it and most time trying to get the 4 bolts out of loader arms working on unhooking hydraulics I can't find any stud guides anybody know where I can get a couple 7/16's got 3 days of off and on rain so I'll be put Zin around unhooking things

 

[damn1981]

Just cut heads off bolts round them on ends and I usually cut groove in them for screw driver
Hydraulics is just pressure and suction line
Pull left side cover under guages makes it easier to get to the bolts

 

[Sinned133]

I'm having a hard time finding bolts no problem finding all thread. I pulled fuel filter off and panel behind I have steering column exposed, its been raining ever since, I think I have most parts off and tractor ready to split. If things go right and alot of prayers I should be ale to split next week

If you have it split from engine and your forward reverse controls (linkage) are mechanical and go through bell housing, now would be the time to re and re them to eliminate any play in the linkage. On our 40B the needle bearing in the bell housing was toast and the pin connecting to the valve plunger was sloppy. Makes for jerky movement, if worn. Perhaps yours is solenoid operated?

transmission is apart everything so far looks pretty good needle bearings and washers went everywhere any suggestions what to use to clean parts besides brake cleaner

thanks for the input I'm going to take all the linkage apart and clean I know the bearings you're talking about

all apart found bad plate reverse clutch I'm kind of worried about all the needle bearings and putting them back together it seems there is a ring attached to the reverse set of gears to another ring does that seem right

There should be no play in that linkage anywhere, from pedal through to spool valve.
