Default Strange Noise Coming from Oliver 77

Hi, Iíve been working on getting my oliver 77 started so i can get it on my trailer to take it to get repaired. I just replaced the plugs and cleaned the carb. This noise has developed around the front of the engine. The noise started then stopped. The engine then died from another issue. We started the engine again. And the noise continued. Attached is a video. The fan belt is loose but i dont think thats it.

While you are checking out the front for the noise, check the crank pulley. I don't think this one made noise, but it is something that could cause trouble in the future. We just put a spot of weld on the rivets and it was fine.

Why don't you take the fan belt off and run the engine and see if it sounds the same. That would eliminate the water pump and generator.

PFT, is your pulley working on the hub? If it is, you can drill one rivet out at a time, drill a larger hole that would clean the hole up like a 3/8" bolt, and rivet a 3/8" bolt in the holes. I would heat the bolt red hot then rivet it. I have done that with clutch disc and it worked. I don't use the threaded part.

The pulley just rotated back and forth on the rivets, was not wobbly loose, the rivets were tight in the hub. We gave it zap with the mig on each rivet filling in the slots mostly. Tractor only sees show and parade duty mostly. Picture of it with the original owners, stopped by on the way home from a parade.

That's OK, I left my camera in the car that day and didn't get pics of any of your stuff. I guess I will have to stop by and do that now that I am closer.

Beautiful Oliver. My Dad bought ours from a farmer across the street. My dad didn’t have the space for the drawbar equipment so he got rid of it. I’m having it picked up soon. Doing a full mechanical tune up on it. New belts, radiator, choke line, exhaust manifold. Don’t have the money for a new paint job tho. I like the original paint anyway. Hoping to convince my Dad to take it to the Rough and Tumble this year.

If the water pump and alternator bearings check out good I suspect you have a loose set of timing gears. Take the distributor cap off and rock the crankshaft back and forth. The amount of crankshaft rotation before the distributor rotor begins to move will give you some indication of the slack between the cam and crank gear.

If the timing gears are loose they will be noisier at lower engine RPM. This is caused by the valve spring pressure on the ramps of the cam lobes which tends to rock the cam gear back and forth. As the RPM increases the inertia on the gears also increases which tends to keep the teeth pulling on the load side of the gear which reduces the noise.
I replaced several sets of timing gears on these tractors for this reason back in the day when I did on farm repair work back in the 80's.

UPDATE: Tightened fan belt. Noise is gone. May be short lived. Still dying after running for about 3 minutes. Carb doesn't have full seal it appears due to one screw not threading right. Ordered rebuild kit. Just going to replace some parts. Still taking it in for service though.
