Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
It is pressurize lubed. There is a passage that goes from the oil pan up along the side of the engine block and over to the top crank bearing, the crankshaft has a small passage from the top bearing surface down to the connecting rod bearing, the lower bearing surface is fed directly from the oil pump to it.
I will see if I can find a picture or diagram that actually shows the oil system for this engine. It may take me a little while to find one as I am not even certain that there is one available but I will see if I can find anything for you.
I have found a little information in the service manual for the engine however it does not show a really good picture of the oil system. I am including a link to the manual and you will find the information on page 120 that explains the oil system.
Thank you it has been a pleasure to assist you.
