One is gt tractor with hydrostat with the lever other is a manual with 6 speed hi lo transmission. I never driven a hydrostat one.i have a hi lo one now and its great for pulling trailer Which one should i make whole? Seems a lever hydrostat is a pain in the rear over a foot pedal one?

Yeah it was filthy. I slapped it back together ot still has same 65 psi with used head gasket going to run it until it blows or makes it to fall. I got a kohler command cv20 in storage.

Why that happen and why its happens in cyl#2 only? Look like rings broke?

I put air in cylinder removed push rods. Air coming from dipstick and where push rods come from. I figured no way to distiguish which one.

This is cyliner on left. The intake valve lash is .003 the exhaust is .029. Leak down test wont distinguish between head gasket and rings will it? Both going to blow into crankcase ,no?

Els 40H777 . One cylinder has 160 psi clean plug other 65 and plug is oily. Could it be valve lash? If not im guessing head gasket or rings.???

I put an electric stater on it. the hydro filter was in the way.easiest way was to flip filter setup upside down. Now it loses hydro power . i can actually push the machine with no drag. sometimes it will be strong when i started then ill lose trans power. it was strong before i did the...

oh thanks never would have figured that out myself. brings up nothing.

anyone have one part number 706799 . its a tapered shaft with key

what puller do i need.

Well pull the crank and the flywheel side of case and it does have replaceable bearing insets but its in excellent condition no streaking or nothing.. I used acid on crank and the aluminum came off! The journal is smooth can catch my fingernail on anything it but has discoloration.(going...

it has 2 wires on each coil. it don't know which wires get power . not like the magneto engines. it has two terminals on each coil.

the gear presses on crankshaft to run the cam is missing a tooth . hope i dont have to buy a new crank.

no camshaft journals are good surprisingly perfect.. crankshaft has hot spots but no scratches i can catch fingernail. same for bearing cap discoloration but no scratches/ I ordered a puller from amazon so i can remove flywheel and crankshaft. Can i use the sump pan or is it no good???? i...

can i use the sump pan?? take a look at the crank thrust surface. I bought engine for $60. Dude said it still ran on one cylinder but no way because camshaft is broken in half So far im looking at rod and camshaft. Hopefully crank will clean up. There was oil in it but it definitely looks...

hey i got an engine with a broken rod. it had oil in it why did the connecting rod break??? The piston and cylinder look good. the rod is broken about 1.5" below piston the rest of rod is in pieces. the camshaft is broken in half but i dont see any damage to heads or tappets... crank...

Hey .I bought a really nice clean engine to repower my mower. it sat until now. Oil must have leaked out over winter . anway connecting rod must be broken because piston not moving. engine still runs really good on one cylinder. what kind of damage am i facing here. I never heard any bang...

I took off flywheel to do oil seal put it all back together now no spark. I disconnected the white wire off them also i believe that's to ground out coils and shut engine down. I noticed coils have arrow on them. I first put them on in wrong direction(upside down) could this have fried the...

Beautiful destruction. I wonder if the valve broke off and did it, or the rod broke and smashed the valve???LOts of crap in the cooling fins but i don't know if that would cause the engine to blow up?? Rocker arm pips were fine. The hole was from the piston and cam chunks that got caught between...

Hey i have a 691v-cs13-r in a hydro walk behind. Something happened that made a hole in the block just below connecting rod cap. cap still has two bolts in it so im thinking maybe the rod broke . The engine has oil in it. 2100 hours on the meter. anyway is it worth rebuilding this engine? I...
