I have an ABN that the PO says has an out of limits Crank & Connecting Rod.  Given the amount of metal filings in the sump, I believe him.  Cylinder & piston look good & can likely be salvaged with just honing & new rings.

 

Q1: What are the limits for the crank & connecting rod?

 

Q2: Is there a bushing kit I can buy or do I need a new undersized connecting rod?

 

I looked in the manual in Manuals section but don't see tolerances.

 

 

P.S. Can anyone tell me when the engine was made?  SN is 2089144.  I tried the Wisconsin homepage thingy, but it doesn't return a build date.

I used the site from the link you included and it said your engine was made in January 1953

 

Any good engine machine shop can grind your crank back to round and install a bearing insert in the rod to get everything back into tolerences.

Does it need to come out to be ground?  I've never worked on a Wisconsin, or had a crank ground for that matter.

When you are investing the time and money to rebuild an engine, completely disassemble it, clean and inspect everything. I'm working on a Kohler right now, it is surprising the problems that can hide. They will come back to bite you later. Good Luck, Rick

Yes, the crank will have to be removed to be machined.

I work at an engine/drive train remanufacture and some cranks get the rod journals welded and turned down to OEM sizing....Others get ground and over-sized bearings are installed in the rods

Kris, what are you doing that makes it work?  I gave up using the Wisconsin s/n tool a long time ago, it never brings up diddly squat for me.  Are you using a certain browser?

Try this link for a manual: the info you want is on (hardcopy) page 16.

 

http://gardentractor...ceparts-manual/

 

Thanks to Dr. Bolens for that.

 

I have one scanned also (50 megs) that you can have if you want it.

Ben,

I use Internet Explorer.

New Canadian's link takes you to the right page. I just put the serial # in the box and click the search button.

The info comes up in the larger "search results" box below.

I'm glad it works for you, Kris, because it sure doesn't for me.  There must be some plugin I need.  I've tried IE and Chrome, as well as my standard Firefox.

 

I'll send you some numbers to plug in.  :D

I retried it today.  I works only if you type the Sn & click the <search> button.  It won't work if you type the SN & hit <enter>.

You don't happen to work at Jasper Engine and Transmission do you?  I toured it back in '85 when I was in the Army.  I was very impressed with the company... no whiz bang technology other than a molten salt system that burned off the oil, grease and old gasket materials form engine blocks... probably stress relieved them, too, LOL. What they did have was a good corporate attitude that encouraged productivity and innovation, but also help a worker's feet to the fire if he screwed up an engine-basically had to rebuild it on his own time...

 

We were looking for a place to help overhaul the aluminum 6V53T Detroits in the M551 Sheridan reconnaissance vehicle. Nothing came of it but I still remember that trip.

I have an ABN that the PO says has an out of limits Crank & Connecting Rod.  Given the amount of metal filings in the sump, I believe him.  Cylinder & piston look good & can likely be salvaged with just honing & new rings.

 

Q1: What are the limits for the crank & connecting rod?

 

Q2: Is there a bushing kit I can buy or do I need a new undersized connecting rod?

 

I looked in the manual in Manuals section but don't see tolerances.

 

 

P.S. Can anyone tell me when the engine was made?  SN is 2089144.  I tried the Wisconsin homepage thingy, but it doesn't return a build date.

 

One thing you can do to extend the life of your crank is to have it turned only enough to clean it up instead of the next undersize bearing.  Then, buy an undersized connecting rod and have the machine shop fit it to the crank.  I did this on my Kohler K341--I had a clean crank that was .001" out of tolerance for standard... works great!
