What engine you have doesn't matter.. what transmission you have does.
Lining worn to to improper use? Rear engine seal leaking on clutch? Improper adjustment?
Your adjustment isn't on the pedal, it's an adjusting nut on the end of the cable on the transmission. If the adjustment on the "engine" (do you actually mean the cable on the transmission?) is out all the way, then it is time for a new clutch. Just read the listings on here for clutch removal. It should only take about 30 minutes unless you are a complete idiot, then it will be about 12 hours.
There is NO adjustment on that year. You either have a BAD Clutch slave cylinder are the clutch and pressure plate is worn out.
Sounds like your clutch is faulty or it may need adjustment.
When you engage the clutch and the engine sits there spinning: it get's no traction OR when there is no pressure on the clutch pedal: pressing it changes nothing.
On the 94, the clutch gable goes through the firewall at the top on the drivers side of the engine compartment. The adjustment is where the cable meets the firewall.
Does it go into gear with the engine off? If so, I'd be suspicious of the clutch adjustment.
rotate engine until adjuster is on the bottom through the hole on the bottom of the bell housing,wedge something between the seat and clutch pedal it has to be pushed down to turn the adjuster
To adjust the clutch on a John Deere GX75, first, ensure the mower is on a flat surface and the engine is off. Locate the clutch adjustment mechanism, typically found near the clutch pedal. Use the appropriate tool to loosen the lock nut and adjust the clutch cable tension until there is about 1/4 inch of free play at the pedal. After adjustment, retighten the lock nut and test the clutch operation before use.
The clutch cable which runs from the top of the firewall on the drivers side loops around in front and below the engine to a bracket on the passenger side of transmission. there is an adjustment nut there.
I'm not a mechanic / technician but a 1996 Ford Ranger has a hydraulic clutch ( the clutch fluid reservoir is in the engine compartment on the drivers side , by the power distribution box ) so as far as I know there is no adjustment like there is on a cable operated clutch
