Can I get your opinion on why my Hatz z 790 is not turning over easily? Starter looks new and brushes are fine. Battery is new. Seems like the compression stroke stops the starter. With injectors removed it turns over fine.
Have you checked the valve clearance (valve lash) ? Is there liquid in your cylinder when you remove injector? Might have a leaking injector causing a hydrolic lock. When was the last time this engine ran ?
@@martinst-amand5117 Thanks for the quick reply Martin! I purchased the engine at an auction, so it I am unsure when it was last run. Ugh, a hydraulic lock. That could be it. Hope I did not damage anything, like a rod. I seriously wonder about the engine lying on it's side for an 15 minutes is the issue. Oil may have crept into areas that it shouldn't. I did not see liquid when I scoped it. I will do a snake camera of the cylinders and present it here on youtube. I will tear in to the top-end today. Again, thank you for your reply !!
@@urgentcareguy3 Before removing top I would remove injector and try to put them outside of the engine and crank engine, you should see if it leak or spray nice and at the same time if there is fuel/oil on top of piston it will be blowned out trough the injector hole..If it dors blow liquid out and injector are ok it might be because of what tou said ! Just clear it with starter and start it ! Might just smoke for a litlle and you are all set...but if it was at auction might be more major than that !
@@urgentcareguy3 seem pretty clean, but like I said, Check valves lash 0.1 mm (Metric), if Ok, remove injector and injection line outside engine and try to crank (watch so you don't get sprayed with the fuel 180 bar injection) you should see if your engine is injecting fuel properly and check if you see any liquid cumming out of the injector hole (put a rag over so if there is liquid it will not spray all over).. Also you might want to put your oil filter on and check oil pressure with a gauge if possible. Hydraulic lock will be if you have liquid between piston and cylinder head.
