Straighten the old ones or weld them if they are broke to get engine going then worry about finding replacement 1 Quote
Lazy WP Posted October 31 Posted October 31 Case SC or DC have push rods like that. I don’t remember which one. Been 35 plus years since I had either of them apart 1 Quote

acem Posted Friday at 01:25 PM Author Posted Friday at 01:25 PM In having difficulty finding the pushrods this side of the pond. I'm going to Houston area this weekend and plan to hit some marine salvage yards while I'm there. A machinist friend said he could make some if needed. I spoke with the owner who had the boat for some time. When his health went bad a couple years ago he was unable to maintain it himself. Someone was trying to start it for him but was having difficulty. Fogged it with either and it started. But it was running too fast and wouldn't shut off. Killed it by unhooking the fuel line. That was the last time it ran and is probably related to the broken pushrods. So it's been overspeeded and has governor problems. Quote
Rawleigh99 Posted Friday at 03:26 PM Posted Friday at 03:26 PM Part the ends off in the lathe and weld them to new stems! Brazing would also work. 1 Quote

just Dave Posted Friday at 05:22 PM Posted Friday at 05:22 PM Volvo seems to have a wide variety of construction equipment, they might ave a cross-over part? 1 Quote
acem Posted Friday at 08:33 PM Author Posted Friday at 08:33 PM Anything is possible. I checked their online website and got part numbers. They only come up fitting a few small marine diesel engines. Not many industrial applications for a 3 cylinder 30hp diesel engine back in the 70s. Quote
