Case 310 wont stay in Reverse help needed

Hi all,

New to the forum, looking for some help with my 1958? 310 case. I bought to use a blower on my lane way. Went over tractor when I bought it, installed a new seat, changed the oil, adjusted the valves, repaired the air filter, put new plugs in, put a new coil on, greased 1000 nipples, put a new set of tires on the back, getting her geared up for winter blowing.

Got some fresh snow yesterday and fired her up. Blower works great, hydraulics work good and clutch works good too. I am having an issue with it popping out of gear in reverse however. it will stay in gear if I hold my hand on the lever or my leg when I'm turned around looing at my travel path. I feel this will be a large PIA if I have to constantly keep pressure on the lever when blowing as that is what I mainly do with the tractor.

Is this a common issue?

easy/hard fix?

I took off the cover to the gear box. the cover comes off with the shift lever attached along with 3 shift selectors. everything seems to work smoothly, and I don't see anything bent (to my knowledge) Looking at the gears, as few look to be ground on one side. Is this my issue?

First tractor, so need help to identify the problem.

thanks for any suggestions in advance.

First port of call for me would be the detent springs (weak/broken) and pins (worn pointy end) and slots in the selector shaft (groove worn into it by the pin). Likely a combination of any or all three. Beyond that worn gears/bearings - much deeper into the innards.

I cannot speak to your issue, but one similar in a 1950 VAC Case. It would pop out of 3rd gear with any momentary decrease of power or load. I found it to be worn gears. Partially from previous owner not allowing the transmission gears to stop turning before shifting, grinding the gears and I'm sure just normal wear as this would have been the common gear to do several tasks. Reverse gave me problems also, there was a worn brass bushing the reverse idler gear would slide on, was worn out, more than likely from low/no gear oil in the transmission. I replaced the bushing and gear. Your looking in the right place. I think you will discover the gears are rounded off from abuse or wear. Tough to find this out right when you need it most, maybe for this winter you find a rear blade to get you thru til warmer weather and transmission tear down. gobble

More than likely your reverse fork is bent and not sliding reverse gear in far enough. Remove the 4spd cover and look at fork for abnormal ware. You may be able to apply some gentle persuasion to straighten the fork. they weren't very stout.. If it breaks, they aren't that hard to find.

If it turns out to be a bent fork, that would be a fairly easy fix. If gear replacement is in order, I would use a bungee strap to hold pressure on the shift stick in reverse to get me thru the winter. Then, would have time to fix it when weather lightens up.

Transmission is not synchromesh, wear on one end of the gears is from grinding in w/o stopping travel. Common, not usually a problem.

If not a bent fork, check wear in notches, balls, weak springs.
