crazycars Posted August 31, 2019 Share Posted August 31, 2019 Need all parts for oil pump system for 1928-51 Buick 6 cylinder motor: pump drive, coupler, cam gear, oil pressure valve, anything else related. All I have is the base. I won't haggle, will pay your price. Thanks. Link to comment Share on other sites More sharing options...
Jim Bourque Posted August 31, 2019 Share Posted August 31, 2019 Are they the same as a 25 Master 6? Link to comment Share on other sites More sharing options...
crazycars Posted August 31, 2019 Author Share Posted August 31, 2019 I was told 25-28 would fit. Have you got parts? Link to comment Share on other sites More sharing options...
Jim Bourque Posted August 31, 2019 Share Posted August 31, 2019 I have some 25 Master parts. I will look in my spares when I get home on Tuesday. Link to comment Share on other sites More sharing options...

Jim Bourque Posted August 31, 2019 Share Posted August 31, 2019 You have the pressure relief as it shows in your picture from another thread. I am 99% sure I have all the shaft pieces, not going to be prefect but certainly serviceable with a little work or I could make you new ones. The parts I need to look at when I get home is the 165240 oil pump shaft bearing. If my old memory serves me correctly I have 2 ? of those but I think 1 is broken. As far as the gear is concerned, I have some used ones but I would recommend getting a new one from Bobs Automobilia in Califunny. With either a new gear or a used gear the shaft will need to be shimmed, drilled and reamed for a Morse taper pin. The top picture is your pressure relief valve. I would recommend that you take it apart to verify the spring is intact and the plunger and seat are OK. Inspect the tubing for cracks. The oil pump bottom plate should be looked at as well as typically it will have grooves worn in it. Resurface if needed. The pump drive gear to pump housing should be bushed to remove the wear as well. I also have info to upgrade the pump to modern gears if needed.

crazycars Posted September 1, 2019 Author Share Posted September 1, 2019 This information is REALLY helpful! You are a life saver. I've worked on dozens of 20's and 30's cars in my time, but this Buick is new to me. Thanks a million! Link to comment Share on other sites More sharing options...

Jim, I'm going to take the 3 hour drive Tuesday afternoon to the garage where my Buick was stored and look for the missing parts. The place is a real mess but there's a chance I might find the oil pump parts . Before you take any action, let me get back to you. I'll write you Tuesday late afternoon. Thanks for everything.
