Farmall B Engine ?

Postby Cub-Bud » Thu Jul 08, 2004 10:09 am

I have read in the Farmall A and B service manual and in Guy Fay's book Farmall Letter Series that the valve seats in the A and B should not be replaced with inserts. Why :?:

I would guess because of the inherent uneven cooling of the thermo-siphon cooling, that it would be posible for the inserts to drop out of the head and damage the piston. That happened to my father with a 434 IH many years ago. The mech said to lat it idle for a few minutes after hard work so the head could cool evenly. Course it had a water pump too. :idea:

I had the head on my '45 B farmall totally re-worked; new valves, valve guides, valve springs, valve seats, plained, magna-fluxed...the works. I hope I have no trouble. :roll:

I posted your question on the Red Power Magazine forum (no replies), and on the Farmall section of YTMAG. Got 3 replies on YTMAG from people that had installed vlave seats in A or B, and had not had any problems.
If you are not part of the solution,
you are part of the problem!!!

Thanks, John. It really makes no sense why they could not be replaced. Maybe modern technology has outrun the problem and everyone has forgotten why it would not work at first. :roll:

How is my step-cub doing :?:
