Does anyone know the corect way to install this oil pressure relief valve. John Deere parts shows the spring goes in the block first then the valve. It just doesn't fit right and spring jams in the hole this way. Looks more like the spool should be in first, point into the spring, and the spring in last. I need to have this work the first time. Thanks, Doug

The valve will go in first then the spring with the threaded cap retaining the spring. There may be a washer or two in cap used to adjust oil pressure. The valve orientation should be determined on how it fits the spring and bore. The later valves are different than the older ones. The older ones had a pointed end on them that went in towards the engine first, newer ones are more of a spool type looking valve I think it will only fit one way. Good Luck, Dave W.

I should have called it the bypass valve rather than relief, goes into block before timing plate is put on. There is no access to this valve after engine is assembled. Part numbers are R111137 spring, and R111135 valve. Thanks Doug
