I mean if the piece that broke off got into that cylinder, god only knows what it did in there. Could have messed up the piston rings...idn but unfortunately the only way to find out is pull it apartNothing I can etch my finger nail on. The cover plate is pretty etched up. Would this be the cause for low compression in my pto cylinder? Are you supposed to be able to turn the rotary shaft by hand? Because if so I cannot…
Sounding like I’ll have to…I mean if the piece that broke off got into that cylinder, god only knows what it did in there. Could have messed up the piston rings...idn but unfortunately the only way to find out is pull it apart
and the rotary valve shaft is conected to the crank by a gear so if you spin the crank the RV shaft should spin toSounding like I’ll have to…
When I spin the PTO the RV shaft does not move…and the rotary valve shaft is conected to the crank by a gear so if you spin the crank the RV shaft should spin to
not an expert, but that cant be good. the gear on the RV shaft is made of brass, so its for it to be stripped of its teeth.When I spin the PTO the RV shaft does not move…
You would think I wouldn’t even be able to turn the engine over if that’s so.not an expert, but that cant be good. the gear on the RV shaft is made of brass, so its for it to be stripped of its teeth.
nah, the crank will spin with that gear stripped, but the RV shaft wont. look at pictures or videos of the bottom end of the engine and you'll see what i meanYou would think I wouldn’t even be able to turn the engine over if that’s so.
Literally what I just did lol. Yeah you are very much correct… can’t wait to pull that shaft and see how chewed up it is. If this motor was rebuilt would they have used different sized cylinders? Or can I just order up some spec sized rings?nah, the crank will spin with that gear stripped, but the RV shaft wont. look at pictures or videos of the bottom end of the engine and you'll see what i mean
top of the pistons will say like .25 or .5 on them for .25mm over or .5mm over. i looked at your pictures and cant see anything on yours so you might have to get some of that build up off them to see.Literally what I just did lol.

Thank you for the help with everything it’s very appreciated. This forum has helped more than I can say.top of the pistons will say like .25 or .5 on them for .25mm over or .5mm over. i looked at your pictures and cant see anything on yours so you might have to get some of that build up off them to see.
Okay, I’ll replace rings, replace RV shaft, and RV degree wheel. Should I bother looking for that chipped piece that came off the degree wheel?with spark plugs in, the engine is compressing air and thats making it difficult to spin. with them out it should spin easily
your going to have to really inspect the pistons and cylinder walls to make sure there isn't any damage. you really should look inside the cases to maake sure its not in there and didnt cause any damage. plus all that brass from the RV shaft gear had to go somewhereOkay, I’ll replace rings, replace RV shaft, and RV degree wheel. Should I bother looking for that chipped piece that came off the degree wheel?
Will do. I’ll post back with my findings.You really should split the case to clean and inspect everything, especially with the brass gear being all chewed up there will be little pieces of brass shavings all in that RV.
