some more pics. pic 1: Freshly honed cylinder 2: crank case reinstalled on deck pic 3: reassembled engine pic4: mower in the lawn was taken today after I cut the back yard with it.

 

Doug,

Nice looking machine. I agree your back yard has nice lines in it. Thanks for the project pics. :fing32:

 

So its good for another 30 or so years eh? :thThumbsU

Also I notice on your new 2 ring piston that both rings look identical...My 2 ring piston in my 'F' motor has one ring flat on both sides ( like both of yours ) and 1 were the ring is flat on oneside and concave on the opposite side. Any idea which one goes on top? I disassembled without noticing the differences and can't remember which ring goes where...

Also I see you have a Lawn Boy tool kit...have you found it to be a neccesity or could you attain the same results with everyday mechanics tools???

 

is that a bonnaville and a bmw in the garage

 

Thanks for the project pics, Doug. Thanks to you, here's another OMC L-B restored and given a new lease on life. :congrats:

Nice car collection, too. :fing32:

Bonneville is what I would guess on the silver car. Guessing around a 1967. The other car I think is a Chrysler. That is if it is one I have seen in his Picture trail collection. Guessing a 1968 on that one. Let us know Doug if we are close. mg:

 

Thanks guys,
The silver/blue car is a '65 grand prix and the tan car is a '65 chrysler newport.
Hopefully this lawnboy should last many more years! As for the F engine piston rings, The squared ring is on the bottom and the beveled ring goes on top, with the smaller side of the ring facing up. If you have the top ring on upside down, it wont compress in the ring compressor.

As for the Lawnboy tool kit. VERY handy to have. The tools make the job so much easier and faster. I survived working on these mowers without a single LB tool for quite a few years. Last year I bought this kit on ebay and was the best thing I ever bought next to a lawnboy mower. The most used tools in the kit are the crank seal installer and remover, armature plate needle bearing retainer (fits over the crank, as you slide the armature plate off the crank, the retainer slips into and retains the needle bearings.
The ring compressor is very handy too, expecially for the F engine. The kit I have is the best one to have as it contains every tool you need to service the C, D, F, and BBC mowers.
Having the seal remover is an absolute must as you do not need to take the engine apart. Thats what I used to do, tear the entire engine down just to change a crank seal as there was no other safe way of doing the job. That being said, I think every lawnboy owner who has a few of these machines and wants to keep them going get a crank seal remover and installer.

 

Is there a part # for the tool kit? I am interested on the basis that I want to get/rebuild engines for LB's...

Thanks for explaining the rings...So to clarify, the top ring is the concave ring and the concave portion faces down???

Doug,

Well, at least I was close on the cars.

Have you removed a BBC on a Lawn Boy? If so, can you describe your experience with that procedure? :thThumbsU

 

Excellent engine rebuild, Doug. Also, glad you got the starter motor going again. If you have time, do you think you could produce another video of your "pride and joy" like the one you did last fall? Would really be great to see and hear the 8228E gobbling up some spring growth!

 

i think i will get one of those tool kits off ebay soon.

 

Great Job Doug! Do you have a special break in procedure you use after a rebuild?

 

Although this is an old thread, please note there is a typo on the first post regarding the connecting rod part number.

The correct part number for the connecting rod with needle bearings on both wrist pin and crank journal end is 606609. This rod plus the 606607 two ring piston enable running the engine on a 32:1 mix.

 

Well, I guessed a Gran Sport Buick. The LF wheel looked like a Keystone from a Buick I used to ride to work in a '66 New Yorker. What a ride.
