yeah I though so too and I tried to lapp the valves myself but it didn't work compression increased but the fix was to have them re-cut the valve seats when I contacted the seller they didn't even know what it meant to lapp the valves. Good thing is I bought it from Amazon and they have whats...

Especially since Kubota is not offering this part anymore. My Kubota dealer said this part is discontinued. The only option is to buy an after market cylinder head and get a valve job done.

I got the correct cylinder head but they did not do a valve job on it they just installed the valve springs and collets and sent it to me. The machine shop fixed everything thing valve seats were redone valve stem seals were replaced and a valve job was performed tractor run terrific now...

Issue finally resolved. Took the made in china cylinder head to a machine shop. 313.00 dollars later cylinder head is installed and working. They did a valve job, new valve seats, and new valve stem seals. I purchased the cylinder head using amazon which is a good thing because they have...

I got a call from my Kubota Dealer and they said Kubota has discontinued the part and they are unable to source it from anywhere else. 19267-03040 D850 cylinder head. I took the made in China cylinder head and my old cylinder head to a machine shop in my town and they are going to re-cut the...

Quick update after going back and forth with the place I bought it from they determined after reviewing pictures they sent me the incorrect part. They are working on crediting my account in the meantime I tried ordering a new cylinder head from my local parts dealer and they are back ordered...

This worked and screw into my air hose. I tried putting air into the head and it seems like it is going in however I don't hear air escaping but I do not have the best hearing so tonight I will have my wife listen for air escaping she can hear an ant fart :)

Not fixed yet by lapping the valves I got them all at 150 PSI each. I think I need to do another valve lapping with different grits. I just ordered the loctite kit that has 120/280 grit compound The valves looked consistent all the way around I cleaned each valve head to remove the compound and...

I lapped the valves twice each and the compression increased from 80 to 150 PSI on the ones that were at 80 PSI and one valve was sticking. Now all three valves are giving 150 PSI which is still below 350 PSI minimum for the tractor. I need to get some fitting to inject air into the glow plug...

I just watched a bunch of videos on you tube it seems pretty easy to lap the valves with the compound and lap tool. Going to pull the head and try to lap the valves this week wish me luck it actually seems pretty easy to do. I will update once I am done and put the cylinder head back in with...

cylinder one front of engine 50 PSI cylinder two middle cylinder 80 PSI cylinder 3 I did not test since I would have to remove the air intake pipe in order to test it. Definitely a compression issue problem is how to I resolve it ? I ordered a brand new head gasket from Kubota and I will get...
