  1. i would think that the radiator from the 41 would be a non pressurized system and wouldn't stand up to the pressure from the super M.
  2. thank you for the many replies. with the help of my brother who got the cowling off for me i got this this picture of adjusting screw i was referring to. i believe this to be adjustment for the remote outlets that are beneath dash .that i want to call cultivator or loader auxiliary remotes,(theses are plugged off) one line returns to pump plate on side of tractor other goes back towards hydr remote valve . In a few weeks when i heal some more i will be investigating things further, i love all of the knowledge on here that one can stir up from the memory banks.. lol thanks first time a
  3. tractor is an early gear drive diesel serial #14261 think 1965 ? haven't been able to get to barn but i know it has the flow divider with petcock on it. the one on my 504 diesel 1966 model controls flow for the steering i know that from trying it . disc cylinder cant be bad it a john deere,, lol used it with the 966 after this and it works fine. when i get more strength back i will investigate this and check out oil cooler and take a few photos thanks for the help so far. and yes i replaced both hydraulic pumps
  4. OK just talked to my brother and he said he lifted partially to turn at each end of the field had no hyd issues til finished with field, disc is a 470 16 ft remote lifted to exit one field ok but seemed to not want to stay up while traveling down the lane to road ,then waiting on traffic disc bled down again but raised had hard steering to turn on to road and back into other field ,came across end of field went to lift to come to barn and no lift or steering . did not check three point to see if it worked . if i am thinking correctly it sounds like the oil cooler can be by passed
  5. the oil and filters have been clean and haven't noticed anything on the screen either time . will try to get my parts manual out today but i believe that there is flow divider with adjustment pet **** up in the dash similar to the one on the 504 .i also remember there being another valve of sorts up there when i replaced all of the return hoses .
  6. i would be interested in one for both a 504 and a 656.
  7. the flow divider ,if that is the one with the adjustment ,i was thinking of playing with and seeing if it would help the steering, the coming back to the barn incident , it just quit steering and couldn't raise disc at edge of the field . was fine 1/2 hr later at re start was full of oil . will have to remove the pto cover and re check that line in a few weeks.
  8. fast forward 6Weeks,,,went ahead and replaced both pumps with new , new oil and filter, test drive seems like problem solved ..? Now wanting to use it more, hooked to hay bine mow ten acres seems ok steering still wandering but 10 times better than before. next day at the fuel barrel ,major hydraulic leak! blew rubber return line behind batteries .. new oil hoses needed are now all replaced . still cavitates ,looses prime ? once it picks up oil seems to be decent . have been over filling by half gallon or so. using it to fill in for other chores ,manure hauling hay tedde
  9. I cleaned both surfaces and used new gasket and sealer when reinstalling cover. tube to pump was not loose. ,I have not seen any leaks near bolster or steering up in dash area, could it be the steering motor is just plain wore out ? tach shows 8750 hrs.. does seem like when i jacked up and moved wheels like it may have pushed air out of system .but it returned after sitting. am just baffled a bit and dont want to spend where i dont need to. I have replaced both pumps in a 504 diesel before but it had very weak hydraulics.
  10. Wandering very loose erratic steering and pump cavitation sound is my main problem, 3 point and remotes seem to work fine. Yes, first narrow front besides h's or m's i have driven . so i changed hydraulic filter and refilled oil ,jacked front off ground and turned wheels back and forth several times with engine off nothing that seemed really worn or loose started engine and turned wheels several times ,cavitation noise went away, drove it a few miles and steering seemed to improve a lot . shut tractor down and restarted several minutes later and pump cavitation noise returned
  11. tractor is a narrow front .. Manuals are on the way.. nothing wobbles or shakes like anything is loose just acts like no hydraulics to hold it in place, kinda hard to describe like nothing to guide it in a straight line. have to constantly steer. tires are both the same air pressure , will get new filter and oil for it tomorrow.
  12. yes am going to get a filter and check that in the next couple of days.
  13. new to me 656 diesel gear drive serial 14261 has had a engine overhaul around 50 hrs ago ,I have all of the receipts for that , has a cavitation sound when first started but smooths out ,steering is really erratic wanders bad when driving. remotes,pto and 3 point work fine.could it be a problem in the bolster? or steering wheel motor ?any thing to try to trouble shoot ? oil level is full. I have had the top link cover off the hose is intact and felt ok , oil was cascading over the rear end gears from above, although oil seemed to be churning from below near pto . oil looked
  14. are there replacement lenses available for tachometers? tachometer on 966 is very cloudy and hard to see. have tried to buff out with rubbing compound .
  15. finally had the time to get steering pump seal replaced , its a bear to get everything lined up to get lines back on .. power washed and degreased seems to work better . so we will see.. once again thanks guys for your helpful advice.
