- 1979 John Deere 301a, PTO, single stage clutch w/ reverser
tractor details
single stage clutch
PTO
REVERSER
3pt hitch
ok, I bought the tractor 3 weeks ago the guy told me the charge pump was bad, within an hour I concluded the clutch was bad. He said, the tractor had just stopped moving and the hydro's had died. he had already changed the front hydro pump and all of the filters. when I replaced the clutch and started the tractor back up, I regained the use of the Hydro's but not the trans (at all) the next night I was able to hook a pressure gauge to the bottom of the reverser valve, the gauge read 150lbs in reverse and neutral (the strange part is, now reverse started working) the gauge went to 24lbs or so in forward. I am looking to verify my suspisions. possibilty A) cracked supply/return line or failed seal to forwared clutch pack? I guess my real questions are because this seems to be a "pressure thing" my clutch pack should be ok? and since I removed the 2 inspection ports on top the reverser valve w/ the tractor running ((not recommended :laughing
(I had already returned the gauge I had borrowed)when shifting into forward or reverse there was plenty of pressure they both shot to the celling of my garage, lesson learned! lol. that being said, since there is obviosly pressure being sent to the forward clutch pack, the failure has to be between the valve and clutch pack or the return line, correct?








on a side note: I found it very frustrating that hardly anyone ever posted how they resolved there similar issues.
