BLOWN KAWASAKI VTWIN ENGINE! Can it be FIXED?!

It's never a good sign when you can hear loose metal inside of your engine! We took the Kawasaki fx730v out of the scag today to see what was going on with it, and we knew immediately that something wasn't quite right! We could hear loose metal sitting at the bottom of the engine case! We tore the engine apart to find the the engine had literally imploded! Can this engine be saved? Tune in to find out!

I would have used clean engine oil for assembly lube, WD40 way to thin for that purpose

[@SavDog262]

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.

Eww. I am confident this set back won’t hinder y’all. Stay positive and keep striving. Lawns, that’s what for dinner

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.

Putting silicone on the cover is a definite no no. Always use a gasket. The last thing you want is silicone contaminated oil. That would be a bad thing.

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.

Cannot strongly recommend enough that you DO NOT use WD40 as an assembly lube. They make a specific assembly lube product for this purpose that is sticky and will not dry out or run.

[@takismantas1159]

Good video but do yourself a favor and use engine assembly lubricant or motor oil. Not WD40.

[@AndrewAMG_]

WD40 is not a lubricant :) Should use engine assembly lube.

[@sherrischneider2794]

Use assembly lube,dont cheap out. All that money for new parts.

Thanks for taking the time to film and post this - just got a FX730V that needs some TLC - good to see DIY maintenance is possible

[@tommieclayton743]

Thanks for that really appreciate your time to show this procedure love from Ireland

[@bobbennett7195]

Great job, Hope it all works out and runs smoothly.

One project after another. If y'all don't get much snow this year, you'll still have plenty to keep you busy

[@lawnboy4492]

Great job, and great video guys. This is so informative. I'm sure this will help so many people. I love the mix of mowing and wrenching lol. Have a great evening.

[@eddiane]

Nice work. Great save on that Kawi

[@martinrobert6525]

Great video impressive nice work! Scag in the fleet soon.

[@ajones5578]

Great video! Where did you get your rebuild kit? Thanks

[@philliphall5198]

I love the Honda engine with replacement rod inserts or rod brging

[@logansimpson5980]

Great video hopefully y’all can get it fixed
