756puller Posted October 29, 2022 Share Posted October 29, 2022 Got a 2394 that's been a pain. I got it all back together for the guy to take and use. It's was moving and shifting thru all the power shift gears so I figured all was good. Come to find out it only pulls good in 2nd power shift. If I hold the brakes in second power shift it will kill the engine. If I hold the brakes in reverse first and.third gears it will just come to a dead stop. I did check the c2 clutch pressure and it's around 190 psi. I can't figure out why I have decent pressure but it will fall flat on it's face. Anyone got any ideas?

snoshoe Posted October 30, 2022 Share Posted October 30, 2022 Have to admit my ignorance of the 94 series. Ones I have encountered were 4 speed and electronic controlled. If yours is three speed. There is no common clutch for the three gears you mention. I would test all clutches while monitoring regulated and lube pressure Quote Link to comment Share on other sites More sharing options...
756puller Posted October 30, 2022 Author Share Posted October 30, 2022 The c2 clutch is the comon link between reverse, first and third power shifts. I'm going to test lube with in the morning. Quote Link to comment Share on other sites More sharing options...

brahamfireman Posted October 30, 2022 Share Posted October 30, 2022 6 speed or 3 speed powershift? Mine had problems in the C5, C6. Only had odd or evens, don't recall. Would move in all but only pull on 1 side. Quote Link to comment Share on other sites More sharing options...
756puller Posted October 30, 2022 Author Share Posted October 30, 2022 It's a three speed forward power shift. Looking at the clutch chart I could have swore c2 clutch was used in first third and reverse. Quote Link to comment Share on other sites More sharing options...
snoshoe Posted October 30, 2022 Share Posted October 30, 2022 Again not real familiar with 94 series. Just checked chart posted by cihtech in 1270 thread. It confirms what I said. Possible model difference? Quote Link to comment Share on other sites More sharing options...
jd560 Posted October 30, 2022 Share Posted October 30, 2022 I have a 2394. Just had to have the power shift rebuilt. At first It would kill the engine when you moved the lever into reverse. Then it got to it would kill the engine when you pushed the pedal in to start or stop movement. Ended up some of the power shift clutches were shot. Got a guy local (southeastern southern Illinois) who knows these tractors inside and out. He totally went thru mine.   I'll send you a PM.

FARMALL FIXER Posted October 30, 2022 Share Posted October 30, 2022 If you have a 6 speed powershift : 1st gear - C1 C2 C6 2nd gear - C1 C2 C5 3rd gear - C1 C3 C6 4th gear - C1 C3 C5 5th gear - C2 C3 C6 6th gear - C2 C3 C6 Reverse - C2 C4 C6 Quote Link to comment Share on other sites More sharing options...
756puller Posted October 30, 2022 Author Share Posted October 30, 2022 Just doesn't make sense to me having c2 clutch pressure at 190 psi. In my mind and experience if a clutch pack was leaking you wouldn't have hardly any pressure at all Quote Link to comment Share on other sites More sharing options...
snoshoe Posted October 30, 2022 Share Posted October 30, 2022 Entirely possible to wear out c2 and not leak. However without knowing regulated pressure. We don't know if it is leaking. Normal for c2 and c4 to wear out first. C2 is modulating clutch and c4 is Transmission brake. Quote Link to comment Share on other sites More sharing options...
756puller Posted October 30, 2022 Author Share Posted October 30, 2022 I did have the power shift apart and all the discs like looked good so I basically just resealed it and hoped it would move after I got done with it. Quote Link to comment Share on other sites More sharing options...
756puller Posted October 30, 2022 Author Share Posted October 30, 2022 Did get the regulated pressure checked at the flow divider it the sensor port. I didn't cap off everything like the want you to in the service manual. I did have the tractor moving and also kicked on all the hyd functions and I had 190 psi.
