Ford 8N 6 V

[gpclarkjr13]

1948 Ford 8N 6 V tractor had been running beautifully all summer. Suddenly hydraulic engagement lever was loose and the and three point hitch didn't work. Called my trusted mechanic who replaced the hydraulic pump. Now PTO and 3-Point work but lever extremely hard to move to engage. Worse, tractor will not now move when in gear. Gears spin when engaged, no spinning in neutral. Clutch pedal and gear shift both feel normal as the were when I last drove and parked it for mechanic. What has happened?

To be clear, PTO also did not work along with 3-point hitch once the lever had become suddenly loose.

Gears spin when engaged, no spinning in neutral. Clutch pedal and gear shift both feel normal as the were when I last drove and parked it for mechanic.

Give us a little better description of this. As general terminology goes a mechanic will not refer to a “gear spinning” unless it is visible to the eye. Are you seeing gears spinning somehow maybe through the fill plug? Or are you referring to grinding or clashing of the gear teeth? Have you tried all of the gears and reverse? If you find some gears work and some do not I would guess the mechanic did not get one of the shift forks back in the gear groove properly when he put the top back on.

Through the fill plug at top of gear box gears can be seen spinning in the gearbox when you shift into that gear. Nothing is spinning when no gear is engaged. All of the gears will spin when engaged. PTO and three-point hitch work when the lever on left side of tractor is engaged, but it is VERY hard to engage it.

Does your tractor possibly have an auxiliary transmission that has slipped into neutral?

Hi gpclarkjr13,
Agree with wore out asking got an aux?

Your post wasnt making much sense for me as 8n 4 speed all gears turn in neutral ( constant mesh ), TILL I realized you must have a 3 speed from 9n or 2n --they are a selective sliding gear design like in the first pic.

2nd pic showes a howard rototilling handle in low, on an 8n with narrowed rear end. If lifted up about 2 inches it goes into neutral, so the rear tires are disengaged from the trans output shaft. ( but not pto or pump )
Your lift would not go up if a sherman in front of the trans was in neutral. The pto would spin slow, freewheeling from fluid tension between gears and shafts, and tires would not turn.

Not getting why a loose pto handle repair solution ended up as a pump replacement?
