257-H No Forward or Reverse

Recommended Posts

BBQVultureWings

So, today I finally got to where I could & very much need to get this !989 257-H ( Number Plate reads:  2217KE02     45561 ) under way. Hooked up a battery to it & starter was not cooperating. Tore the starter all apart. cleaned the Comutator, brushes & about 30 years worth of snot, dust & grime from the spiral splines.... got things moving freely again & well it took right off like it should. Starts & runs like a top. Bigest problem is no Forward or reverse.... started to take things apart to inverstigate & ran out of daylight....I Noticed the fan for the Transmission is jammed up against the right side of the frame ... I wonder if this got hit by something bigger than the tractor or it may have taken a fall off a trailer or truck tail gate or maybe even rolled over. I doubt the roll over because i woud expect more damages to be apparent.... who knows...? I have heard there is an easy fix fir the Hydrostatic Transmissions but I forget where I read it... The Keys for both axels are in their keyways & the left wheel is hangin' on for dear life so gonna rig up a pulling bracket in the morning to remove the wheel. the right came off no problem but thrre's always 1 that has to be a challenge aint there? I atatched a picture of the fan up against the frame it is not the best photograhpy  but I really thiMk it needs to move back about 3/8 of an inch to move freely.... more tomorrow

953 nut

The fan is attached to the transmission input shaft, if it won't turn the transmission isn't going to go forward or backward.

well..... nothing looks bent. 1 thing for sure is the U bolt for the left side axle tube is definitely Not the original. i loosened the nuts on both sides a bit & nudged the Transmission over to the left a bit ( about 1/4 inch to give the fan some clearance. Now the right axle will spin but not the left. I don't Know SHEE-IT about Hydrostatic Drives. I assume it is not getting fluid to that side or it is low or obstructed or all of the above.... Checked the big clear plastic resivior & it is full but its old dirty oil in there So i thiMk changing the fluid would be a good start. The Tractor came with a Spare transmission, a mower deck, a snowblower atatchment & all the brackets n belts to run it. So given the amount of stuck the left wheel has in it's little heart.... I am thiMking I will reove the transmission & Take it to my friends place where I have access to a larger Hydraulic press for such situations...While I have it out I might as well drain it, clean it, flush it out good & maybe even rebuild 1 of them for now so I have a place to start from.... when I have time I can rebuild the other....  I wonder now if  it got hit on the left side & broke the U bolt & probably damaged the transmission.... pure speculation but it would certainly explain some things.... Any help or suggestions would be appreciated.. 

Thank You All. Be back later

So, upon further inspection, The left rear side of the frame is pushed in a little (1/4"-3/8") so I do belive there has been some collision or other impact. I definitely need a new fan for the transmission, a new Drive belt wouldn't hurt either. I understrand that this is a 35 year old machine. That means lots of things need attention. Belts, maybe a few pulleys, some wiring as the headlights don't work. fluids, tires the basic old age woes of this sort of thing .... I decided to pull the transmission so I can take it to to my friend's place where he has a large press to get the left rerar wheel off as I will be purchasing new tires. I prefer to have things in workable order so when I need to take a wheel off for whatever reason, it is not a major, miserable, monumental event... 

So while I have it off, I will be rebuilding it. I have a very significantly steep driveway & I need a machine that is in good to peak condition ready to go, not 1 that just barley makes it.

more tomorrow I'm tired n my hair hurts

Looks like it is gonna be torch action to remove this wheel. The whole assembly will Not fit in the press so we tried fabricating a puller with 3/4" plate steel & even threaded the center hole same as any puller would operate. The bolts started to deform the rim. there's a ton of pressure loaded onto this thing so time for more drastic measures. After plenty of Cussin' n discussion, It is gonna be the cutting torch. may have to destroy this rim but it isn't like we can't get a new 1. Hopefully I will be under way with the next steps of this project Monday evening. I am looking for wheel weights if anyone knows where I might find some really cool inner & outer weights for the 12 inch rims....

So, After Several :angry-fire::ranting: Copious :angry-cussingblack: Profane :angry-argument: Rants :ranting: while wielding various Swing :angry-screaming: Wrenches, Fabricating a plate of 3/4 steel & tapping the center to force against the axle, installed it, loaded it with a large pneumatic impact & socket (probably 400+ ft lbs) a cutting torch,air hammer, an act of congress, an act of God & 3 baby elephants, grinder, More swing wreches, A splitting wedge out of desparation.... :angry-fire:, the wheel of doom has Finally been removed. That thAng has probabaly been on there since 1989 when it left the factory. It Certainly had more Heart & fight in it than some large industrial equipment I used to maintain & repair..... 

 I ordered a new wheel as We destroyed this 1 in the removal process.... :soapbox: I am a firm believer in Preventive Maintenance :soapbox: A little  antisieze compound & the few minutes it takes to do it are just worth it in my ( often not so ) humble opinion. All that having been Whined about & now out of my system, I looked up my part numbers & went to A-Z Tractor's website. They had my rim ( could Not find any 1 on here in the classifieds that had 1 :angry-fire:  :angry-screaming: ) the nearest possibility is a lawnmower junk yard about 180 miles from here & another yard 300 miles..... So I went to A-Z Tractor & Not only did they have the rim they also had the cooling fan for my 257-H Hydro Transmission pump. I was having some trouble with the processing so I called & they were Very Helpful. I would Recomend A-Z Tractor to everyone Because of the Great experience I had in dealing with them. 

 Anyway we are Finally moving forward with this project. I have attached some pictures to justify my whining....
