Kolher courage engine trouble

Hi

I am working on a Kolher Courage engine. Spec XT173-0084. Replace the oil pan because I thought it was cracked. Turns out the gasket was done for. The gears in the replacement oil pan would not turn properly so trying to start the mower destroyed the gears. I used to get 120 PSI from the engine, but now I get 60 PSI, and it will not start. My neighbor informed me that since i messed with the gears I likely have the timing off which will result in poor compression. I am unable to located anything online for the timed position.

If I have not destroyed this engine, how do I align everything for the timed position?

Thanks in advance!

The camshafts have marks, one says IN for the intake, and the other says EX for exhaust. The crankshaft has 2 dots on the gear on it. Line up the 2 dots on the crank gear with the in and ex dots on the cams to time them.

Finally got to work on it today. Crankshaft has just one small dot on the gear. Camshaft has just one large dot on the gear. Did not see any IN or EX markings. A push rod and valve fell out while cleaning so I put it back in and aligned the two dots. Still just getting 60psi. Is it safe to try and start the engine?

Is your model number listed correctly?? Courage engine has two cams one for exhaust valve and one for the intake valve. As Cheese has said both cams will be marked! Take a look at this Kohler link. PBS Net-Compass

Did you get the push rod back onto the valve it fell off of?? That valve is more than likely a tappet or lifter. If you did not get that push rod back onto the rocker arm correctly this would leave you with a compression problem. Have you had the valve cover off to check this?? Also I beleive the Intake camshaft has a slot in the bottom of it and it should align and sit in that slot as it drives the oil pump. You also keep saying camshaft,,if it is a courage engine it has TWO camshafts like Cheese has mentioned. Double check your work,,make sure the exhaust make is for exhaust valve and Intake make is for intake valve.

OK Should I take the head gasket apart and make sure the push rod is correct?

Just take the valve cover off and make sure pushrods are on the rocker arms.

Agreed. I saw courage engine and immediately thought of the bigger riding mower engine with twin cams. Just line up your marks and the valve timing is set.

Top push rod is not on rocker arm. Not even in the valve. Why does it keep falling out?

Going to fish it out of the oil pan again.

If the valves are sticking open, the push rod will fall out. Also if they are not adjusted properly.
