I have had a 1983 JD 318 for a few years now as my primary mowing machine and I love it. Recently, I picked up a '87 and '92 very inexpensive(read that as neglected) 318's that I hope to get working again. I'm curious about the hydros. I'm confident that I can get 1 or both of them running, but what should I be concerned about with the transmissions when I get the engines going? I know the fluid and filters will need changed, and one of them definitely needs relief valves. What would you do?

Thanks,
Terry

Are the relief valves sticking? They can be taken apart & cleaned up if that's the case. Those hydro's are tough, so a good chance an oil & filter change & get the valves working, and you'd get years of great service.

There is also a source to get those relief valves new, but a good cleaning should get them back into working shape. It isn't from JD but it is a standard part available from another company, I just can't remember where right now. As others have said fluid and filter change and it should be alright for another couple decades.

Nothing like learning by getting your hands dirty. I agree with what all has been said, the hydros are tough units and a good oil and filter change and they should be good to go other then cleaning the relief valves or replacing them if need be.

Congrats on the new tractors. 3 318's -Wow, they are rare in these parts. I don't think I have seen more than 3 of them in the last 5 years total. There are lots of the newer JD's but the older ones are not common at all. I just picked up a 314 and I have only seen 1 318 for sale in the last 6 months.

The 318 Hydros are fairly tough, I’d say change out the fluids and filters and run them. Unless you know there is a problem like your relief value. Some units have creep where they will creep forward even in neutral, I’m not sure there is a fix for that.
