Hey, I want to take off my oil pressure regulator, the one under the rearmost plate. What size socket is that? Do I take it out in one piece? SOrry, im pretty new at these rotaries and my crescent would not fit in there. THanks

 

im talking about hte rear oil pressure regulator, Thanks

 

I take and installed mine 2 weeks ago and I dont remember right know the size. But I think I used a Craftman 1 1/8 socket and 1/2wrench to take it out. If you have an ajustable wrench you can put the wrench over the regulator and measure his size and the buy the socket.

 

I was lookinga thte clearance I have, I might be able to use a socket, but there is little room back there. Thanks though, Anybody else?

 

i used a 26mm wrench and grinded the hell out of it to fit when the motor was still together. if it's in pieces just use the wrench unmodified or a 26mm socket.

 

Thanks, I finally got it off and the new one on. The weird thing is my s4 opr was a smaller size than the s5 opr. The part that threaded through was the same though. Thanks
