    Beveled sides of the connecting rods at crank should be opposing. The flat sides go against each other and the bevel sides point away. You put one piston on the connecting rod 180 degress off. May not make a difference in the short run, but oil flow between connecting rods at crank will be diminished.

    Ok. Thanks. I caught it in the video. Both pistons are the same part number. What was confusing me was that the obvious DEI hire at Kawasaki told me that the pistons were different for each cylinder. They’re not different, they’re the same, in case anyone else runs into this issue. I couldn’t read the numbers on mine because it was blown out from a broken valve.

    I commend you for the effort to repair this engine as opposed to scrapping it; I think it was the correct move. My guess is the most difficult part was finding someone to bore and hone the block. However, I need to join the chorus in the comments about the use of WD-40 as assembly lube. What are you thinking?? You spent north of $700 in parts and a not an insignificant amount of labor but then cheeped out on assembly lube. If this engine doesn't fail prematurely it is just pure luck. Do yourself a favor, spend $12 on a tube of Lubriplate.

    They make assembly engine Greece just for what you are doing. Wd40 is a more stir repellent. But you can fill the engine with oil and shake it around before starting it up. I went to engine Machinist school for 2 years. I would take the plugs out a spin it several times before trying to starting it.
    Thanks for the information and video. God bless you.

    Just my opinion but, I think you should have followed the inside profile of the crank case cover so oil won't seep out of the bolt holes.
    I know you do this stuff WAY MORE than me. Just a thought. Looks REALLY good though! 👍Good luck, God bless.

    I always just buy a new engine at $2-$3k and install. I have never taken the time to rebuild a mower engine - Usually by the time i replace them they are junk with 3500-4000 hrs on them. Im not a mechanic-u guys know all about rebuilding them but for the average guy running a business they dont. My exmarks lazer Z Xseries machines new retail at 18k-$20k! So replacing the engines is nothing compared to that. I will be replacing a Kawi 921 with 2500 hrs on this off season for $3100. The big Parker pumps last for ever-I have never replaced a pump on any exmark machine ever. one machine is on its third engine and the pumps running strong. great video man

    I would apply the sealant onto the inside of the bolt holes so that no oil can leak past the threads of the bolts.
    I recently rebuilt a Honda GSV190 lawnmower engine for my fathers lawnmower because the engine was very smoky on startup,the lower compression ring was out of specification & the rings were just tired after 20 years of use.
    I had to order a new standard sized piston because the grooves were machined to accept thinner piston rings & the original rings were no longer available & expensive if buying new old stock rings.
    I staggered the rings 120° apart although I staggered the chrome faced scraper rings for the oil control rings apart by 10 millimetres as per Hondas instructions although the expander ring wasn't fitted so it would line up with the gap,so both compression rings & the oil control rings gaps were spaced 120° apart.
    The T mark on the compression rings had to face the top side of the piston.
    The arrow at the bottom of the piston was positioned to face the right hand side of the engine or the muffler side of the engine.
    Honda had no recommendation as far as letting the RTV silicone sealant skin over before finally torquing the bolts down to 12 Newton Metres & in sequence.
    I used Permatex red RTV silicone sealant because that was what I had on hand after I used it to replace one of the exhaust header gaskets in my car !

      That was my guess but I thought it was a machine you were using so I didn’t wanna hint that you forgot to check the oil lol. I have a Deere 930M with the 801v that burns oil and has since it’s first day. John Deere says in the book that they use half oz per cylinder per hr. Like they’re designed to do this to last longer maybe? But I hate it. It has 1800 hrs on it now and runs strong as ever but you gotta keep track of the oil closely on it.

    You can't forgo the crankcase gasket as it's used as a shim to get the proper spacing. Sorry my friend for the criticism but your viewers need to refer to the service manual, as different engines go together differently, piston ring orientation, connecting rod orientation etc. I've rebuilt dozens of engines and always refer to my cheat sheets with the information from the service manuals. The service manuals are free on-line.

    You put the rods on backwards! the bevel sides need to go against the side of the crank journal, this give the proper clearance between the rods. The way you have it the rods are binding against each other, this is why you have so much friction when turning it over by hand. WD40 is not a lubricant, don't use it as assembly lube.

    The only way they’re beyond repair is if the cylinder wall is damaged too badly or the block is cracked too badly. Even a cracked block is fixable with the correct welding or even a really good JB weld guy…. And even soldiering… drill small holes around the crack and in the crack. Get a soldering gun and melt you a good metal and fill the crack good then JB weld over it. It’ll hold. Crank case has very little to Zero pressure in it. May at the most has 3 or 4 psi from a little ring blow by but the wonderful thing about these motors is that they’re always rebuildable. Cylinder wall damage is really the only limit. It gets nasty in that bore wall

We have been working on this on down time (after work, and days where we are unable to work due to pouring rain, etc) all said and done from start to finish tear down, machined, reassembled we will have anywhere from 8-10 hrs into the rebuild. When we initially tore this down to diagnose what happened a new engine at that time was unavailable, that was a few weeks ago, not sure if that has changed. A new engine is going for roughly $3,000 so at 8-10 hrs we are paying ourselves anywhere from $281.25- $225 an hour to rebuild this.
