Troy Bilt Cultivator

[dangier_VA]

Have a question on a Troy Bilt Cultivator. It is a 4 cycle gas tiller that has been blowing the crankcase and valve cover seals. Found that the crankcase vent was plugged by the crank seal assembly. Of course it is out of warranty... Finally purchased a new crank assembly and am reassembling. Anyone know how the camshaft gear lines up with the crank? It has been apart numerous times and I don't recall the original line-up. One of the times I ran it, it was popping back through the carb at higher speeds, but ran. I have attached a picture showing the camshaft gear on top of the hole it drops into. The gear has a line (shown) that is lined up with the end of the crank tdc between two lines on the case.
Anyone had this engine apart?
Thanks in advance.

dangier_VA. At TDC exost stroke, the intake valve is just opening and the exost valve is just closing. Rock the camshaft, so both valves are opened the same amount. That will be TDC exost. After you mesh the gears, remember to rotate the crank one full turn to return to TDC compresion, to set the timing.

Thanks for the reply. Lined up the gear and crankshaft as shown, run through the cycle and confirmed the intake and exhaust valve operation at the right time. Put everything back together and it runs like a champ!
Many thanks.

Dangier VA, Glad to help. There are a lot of engines that don't have proper timing marks, so this is a good thing to know

What's the difference between a tiller and a cultivator?

I'm surprised that no one has ansured this one for you. I'm not sure but I think a tiller, has it's own engine. Rotavater is a tiller that hooks up to your tractor. A cultivator, is big hooks that you hook up to your tractor, that rips the ground. If the ground is well worked, then you only have to use a cultivator, usally it will have wege type cutters bolted to the tines on the cultivator. If you take the winged cutters of the cultivator, then you can rip the ground up before you till the ground.

Thanks for the description. If I understand correctly, a cultivator was/is towed behind the tractor to tear up the ground before tilling with a disc. My Troy Built Horse is listed as a rototiller/cultivator. I assume it is listed this way because it performs both actions as it goes.

I think that you got it. If you rototill, then you don't have to do any thing else

I have a disc which came with my tractor, but I haven't ever tried to use it.

The last time I used disks, I was 12 ish. We had a 1949 massy pony tractor. I would plough the feild, then disk perpendiculer to the ploughing. The more angle you put on the disk the mor they dig.
