I wouldn't count on it. Doesn't have the correct oil pan mount for a JD garden tractor. Also, I don't think the flywheel blower housing would fit snugly in the frame of the tractor. Not to mention it needs the proper air cleaner assembly, dipstick, and relocated coil.

 

Thanks for the quick reply I didn't know if I could swap the parts from my engine

 

Flywheel is wrong, size of crankshaft ends sizes could be wrong too. Why no shots of where the PTO would normally go?

 

Here's another picture

you have an onan CCKB engine.
for your 318 it is,
to tall,
to wide,
to heavy
and no way to hook up your driveshaft.
only a few internal parts would interchange.
thank you. boomer ( the used onan engine parts guy,
also NOS and new )

 

Thanks for the information although it wasn't what I wanted to hear. I have a 318 with the P218 and a broken rod. I purchased a 318 with the B43G with a 200 hour rebuild. Apparently it wasn't done right because when I started running it hard it started smoking and blowing oil.

I'm in the same boat. "Fresh Rebuild" and it blows oil out the breather and won't hardly run past half throttle. In the middle of tearing it back apart now. It ran good when I got it then after running it some something must have gotten out of whack.

 

I think the guy who put the 200 hours on my engine did it very gently and then I got a hold of it and actually ran it and blew it up. Now I'm just out $1,300 for a few hundred more I could have bought a new engine for the one I had

 

You got taken by a fly-by-nighter, don't get to upset, but learn from it. There are a lot out there these days, they are a looking to fix just enough then flip it type operators, looking to make a quick buck. So when you look at buying, always test it if you can, by using it it, first to see (at least a half hour) this will bring the engine or tranny to ops temp then listen and feel for anomalies.

Know what you want, do the work, research. Like Mr.Beef does

Anyone who says it just needed rings/pistons in either a horizontal or v configuration and has high hours is not being truthful. Always check the paper trail, if not there don't pay, walk away. He will find another sucker willing to part with their money. Or make a list of what is wrong/broken, know what it will cost to fix, subtract from their asking price.

 

The P218 couldn't be rebuilt/repaired? $1300. could/should go a long way towards that.
So now you have two 318s that need engine work? Absolutely no disrespect intended - just curious.

 

No disrespect taken and I did ponder that question very heavily before I made the move. I drove the tractor around his yard and mowed little bit of grass but his yard was flat smooth and the grass was very short not much of a test. The tractor with a broken Rod still runs so I'm not completely out of a lawn mower yet

 

So in everyone's opinion here what is the best engine to repower the 318 with Briggs & Stratton Kohler or Honda

 

Spend the $1300+ to get it rebuilt correctly. It will last a lot longer than one of these light Honda or Briggs repowers will. People swear by them but in my opinion if you're gonna keep one of these old pieces of iron running, you have to keep it's original American-made powerhouse with it. I've never worked on an air cooled engine as stout as an Onan.

 

The rebuild kit alone is $1,300 now and I have no idea who in this area could rebuild it right

 

Hence a search for places (look for certification in small engine repairs), on engine machine shops, talk to any repair facility that actual repairs engines. Many will buy crate engine replacements, but others like restorers will use engine machine shops to do the analysis on weather to repair or replace (blocks, cranks, heads, valves, rods, etc). It takes some work, but you will learn a lot.

If that seems to be to much for you, then why did you buy a 20 plus year old LGT. You should gone and bought new (big box store for a 5-10 year throw away) or spent even more a JD dealer with a full line up of equipment for a proper machine with hopefully no problems.

 

Dealing with old machines is not really a problem I own vehicles or three times older than this lawn mower it's just the fact that most people around here don't know how to work on onan or are not interested in working on it but I'm going to make a few calls tomorrow

PM your email address

 

Well I did find a local shop that knows what they're doing and will rebuild it somewhere between $2000 and $2500

 

John Deere 318,

Between Boomer and all the knowledgeable folks on this forum, you should be able to get back up and running for a lot less than the $2000-$2500 you were quoted.

 

john deere 318
i,m going to send you a P.M.
re NOS onan short blocks.
thank you. boomer ( theused onan engine parts guy,
also NOS and new )

 

Thanks I have definitely decided on going with a rebuilt onan but my finances kinda fell through so it's going to take a little more time that I thought

 

john deere 318
the parts in the short blocks i have
are ALL NEW, and for LESS money
than the parts to rebuild yours.
thank you. boomer

 

Where is he located? I received the email with the information but there is no p.m. yet

 

boomer is in Hastings, Minnesota, Knows Onans very well, Got a lot of my parts from him.

 

I might take that route with the p218 on the other tractor but that price included the complete rebuild kit and all the machine work to make it better than new. This is the same shop that built the engine in my motor home and I am very pleased with it.
