Okay, i remember reading this somewhere, but i can't remember where.

 

Is there brass bushings or pins somewhere in the hydro linkage that can wear out? If so where are the located? My hydro on the 318 is working ok, but kinda jumps when i change speed with the level.

 

Thoughts?

Have a look at JDParts.com and search for 318 in the model search. That will bring up the diagrams for the tractor. I know in the older 300 series there are some nylon bushings that tend to wear out in the linkage where the travel lever pivots. I'd have a look at the entire linkage and replace bushings that are worn and clean/lub it. The pin that attaches the linkage to the hydro on the older 300's can wear the hole in the swash plate lever, creating slack in the linkage. This will cause jerky operation. I bored the linkage end cleavis to take a larger pin (7/16) and this fit tight into the worn hole. Problem solved. I'm not sure how similar the 318 is to the 314/317 I have.

Mine was doing all sorts of funny things. Found the axle mount on the frame broke on the left side. I welded that and tightened all the bolts works great now.

Broken stuff around your transaxle can certainly cause issues.  I welded a cracked frame on my Massey Hydro and that fixed all my jerky problems.
