Found a snap ring at John Deere. Assembled spool valve with float. First attempt at fix is a total failure. Boom does not operate at all now. Must have screwed up o-ring sequence someplace.

Discovered one too many o-rings on spool and now she operates great. Even retained float. Way better to have spent $4.89 for John Deere rings than the $700 for a new control valve housing especially that a $1.00 wire snap ring less than the size of a 1/4" failed. So even though John Deere stated that this item was no longer supported and non serviceable anyway , I had a smart parts clerk cross reference the ring and he found the loader spool for a 318 John Deere garden tractor had a similar wire snap ring. With some coercion and a bit of filing it went on and held the return centering spring steadfast and now the loader operates better than it originally did. I don't know about anyone else but when my tractor is down, my world is just not right. Thanks all who contributed.
