Oliver 1550 Hydraulic relief valve

theking5983 · Jul 8, 2023

I converted my 1550 over to take the 1650 hydraulic pump and the relief valve keeps blowing do I need a relief valve from a 1650-1950 or is there away to set the 1550's I am also looking for a bearing carrier Oliver part number 104 406-A and am having trouble finding it

Th?e relief valves are the same. You have a shop manual

1550 and 1650 are about the same except for the pump and its related parts. I think you have a restriction elsewhere in the system to cause the
relief to blow. Same system pressure, just more flow.

do u have to use the hydraulic res gaskets when you are putting the hydraulic system back together or can u use a good RVT that handles hydraulic fluid

I know, they're BIT PRICEY. I reused mine. Use the better one on top of the pan.
