Engine replacement

[Auto Doc's]

I am working on a Mad Dog mower, Kawasaki engine failed because the rod cap bolts were loose, that is one of many things with their engines that they hide and deny, so the fellow bought a used one, he was told it had a miss probably valve need setting, took the covers off the valve and found another Kawasaki hied and deny, the head was broke the guide that holds the push rod in place, broke off and it swallowed the valve and bent it, so he orders one from Wholesale warehouse, wrong engine, cranks shaft has to be a 1 1/8" X 4.250 length, he had to pay shipping back and got the right one but the muffler won't fit, now it's to find the muffler I have read that Hustler bought them and parts and mowers gone, but he is paying 50 per hour, while I unbox his useless motors and mufflers.

Hello Its Me,

If a rod journal has been worn down from lack of oil and frequent overheating, the rod bolts will loosen due to the excessive knocking that has been ignored by the operator. You found a result, not a cause.

Kawasaki is the last one I would blame for these engine failure problems. A large majority of engine failures occur from customer lack of proper maintenance or just plain abuse.

All brand engines do have their faults, but they show up more as hours of use increase, especially with a lack of maintenance.

I see all makes of engines in my business and a few of them that never make it past 100 hours because the customer never checked or changed the oil since purchased new. I offer oil change service, but no one want to pay for that when it cost more than it does to get the oil changed on their 4-cylinder vehicle. Service parts and oil are not cheap these days

Amazon cheap "white box" filters or Walmart budget oil do not work very well with small engines, and I will not use them.
