I checked the valve gaps and discovered that both cylinder 3 valve gaps were too tight. I adjusted them to spec and the tractor performance is back to normal. Seems strange how both valves on cylinder 3 had some wear? The other valves never moved? Hmmm. Maybe engine lube doesn't get to these...

Hi, thank you. If the gaps look good, I will drain and clean out the tank and install a new filter. I always use fresh fuel and always use the recommended additives but you never know. Since I have owned the tractor (~10 years) I have never cleaned out the tank. So its definitely worth doing...

Hi guys, I have noticed that my tractor started losing power after it warms up. It recently has gotten pretty bad? I just changed out the fuel cap and fuel transfer pump. Glad I did it (since they were the original parts) but it didn't solve the issue. Also, fuel tank and fuel filter are...

Me too, thank you

Hello all, with help from rbargeron, I discovered why oil was not being fed to the cylinder head. The oil Port on the head needed to be aligned to a hole in the rocker arm shaft. If you don't turn the rocker arm shaft just right the oil is not fed into the assembly. After confirming that oil...

Re-looked at the oil flow diagram and now understand the added role of the idle gear. One thing that I could do that wouldn't be horrible is 2 check the port starting from the head then work my way down through the block toward the idle gear. Who knows I may find an old blockage that the machine...

I plowed the snow a few weeks ago just after I completed the rebuild and got the Hydraulic pump working before we all came to the realization of a dry head Will not be using it anymore until it gets fixed Thank you NIW!

Really? I'm in complete shock right now. :eek: I just may take you up on the offer. I feel like I'm so close. I just plowed 15 in of snow like it wasn't even there for god sakes.

I got it thank you everyone. Very disappointed at the thought of pulling everything apart again. I don't have the time nor experience

Thank you Dick. I don't recall seeing drill pictures in the WSM but that doesn't mean that there not there. Will look again. i can always pull a plug out of the block and turn the engine over. Maybe I'll catch a break and find a working oil Port on the Block that is near an oil port on the head

I tried searching around to see if I can get more information on the unused Block & head ports. Wondering if anyone else has any further information on this engine V1902DI? Thank you.

Not sure if I'm following you exactly but I noticed that there are unused ports on the block. If one of those ports is oil I could use it as my main oil feed to an external port on the head as you pointer out? Heck, I could reuse the oil sensor port as my main feed to the head if nothing else...

Jeff Really? Where are you finding this information. sounds like really good news if I can understand what you are saying and not make any mistakes

would like to do is come up with a way of using an external pump to feed oil from the pan back up to the head. Maybe tap right off the oil drain plug. I am thinking that I could modify the cylinder head cover in various places so that the pump sprays oil throughout but I'm not going to take the...

Not sure if I could do this but what I could try to do is is take the rocker assembly off and run a wire through the head to the block and make sure there's no port blockage if it's a straight shot that is

About 6 hours. Plenty of time to kill seals.

anything's possible but I did pay extra attention around the oil port and made absolutely sure the O-ring was in place When I removed the head a year ago during the rebuild I noticed that the previous owner did a good job with the gasket and o-ring as well. That's what leads me to believe that...

so I'll have to come up with a way of pumping oil from the oil pan back up into the head

Spent the day working on the tractor have 2 MPEG videos that I could post but MPEG is not on the list of acceptable file types Tried to perform a compression test using my Junkie compression tester that can not hold pressure and was only getting about 325 PSI per cylinder. adjusted valve lash...

I saw this method on youtube. Will try it and see if the gap is any looser than my normal approach
