Engine swap or rebuild?

Posted by Farmer in the Dells (WI) on July 10, 2003 at 10:06:29 from (66.187.42.24):

Friday my ’47 Allis B goes in for some work. It has developed a “pop” when running that my local shop says sounds like a valve spring or sticking valve. It also needs a new front oil seal and thermostat while it is in. I have another motor on a skid which I am told was rebuilt. It came with the deal over ten years ago but I have not needed it until now. He is also suggesting since we are already there replacing the throwout bearing and clutch along with the pressure plate if need be. He also mentioned that the flywheel may need to be machined. The alternative is to simply replace motors which would take less time and then reduce my labor cost. I heard the tractor still needs to come apart because of its design anyway to get at the front seal if I try to rehab the old motor and find my source of the pop and loss of power. Here are my questions. Would someone with a reasonable amount of mechanical ability be able to handle the engine swap? I am confident with the shop since he worked on one of my larger tractors and it was a good repair of a major problem. This seems far less dangerous to split the B and remount a new engine. I do know how much mechanics do not like taking on projects that are half started though. Getting things in a box usually seems to add to the bill. What are your opinions? What might I want to look for? Would you replace the clutch pressure plate and/or the throwout bearing if it were you? Is there anything else I should be looking at? He says the engine swap should take 1 and ½ days plus machining and parts waiting. I won’t need the tractor for two weeks so time is not an issue. Just the ability. Thanks
