Hello to All ,
Recently, I have owned the Kubota B7000 tractor.
It smokes white profusely when loaded, also turns long to start and has engine blow-by.
Compression 1 cylinder 22 Bar; the second cylinder 25 Bar, while after the oil test 30 and 32 Bar respectively.
Suspicion is the rings and / or pistons and / or cylinder liners
I also checked the valve clearance, it was 0.15-0.25; I adjusted it to 0.2 for all.
I also did a filter-oil-strip service with engine rinsing (I have the impression that the belt is as old as the tractor, > 40 year)
So I'm looking for a service/parts books for the Z650 engine with a capacity of 653cc or any refernce for this one
There is a lot in the network for other engines, but for this one almost nothing, looks that is quite rare.
Below are some photos and a link to the movie showing engine blow-by.
