Piston connecting rod / crankshaft journal has too much play. Best options for this 5hp honda?
Original Message   Dec 4, 2008 9:04 pm
I have here a piston connecting rod that has just a little too much play in the bearing/bushing that connects it to the shaft.  Is there a bearing/bushing that can be replaced or does the whole connecting rod/shaft assembly need to be replaced? This is off of a Honda 5hp horizontal shaft 4 stroke engine that belongs in a honda single stage snowblower (HS520).

I agree 100%. This isnt an aircraft engine that is used in a critical situation. I dont see any major issues and it will be a great learning experience.  Try your public library for a book on small engine repair a similar Honda engine may be discussed.  Make it a fun project and take your time.  Just make a point of getting as much of the grit out of it as possible especially around the rings and grooves.  I have used Simple Green as a soaking solution on my BMW pistons (81 bike with 152,000 miles and runs great!)

Thanks for all the input on this decision.  So I slept on it  last night and I think I have a plan:

I'll  start shopping around for a replacement engine.  See what's out there, what it would cost, and how well it would fit.

Meanwhile,  I'll  toss everything in a vat of "simple green" and hose it down. Then I'll  find a shop manual (I might even be able to resell the manual when I'm done with it) and spread all the parts out on the dining room table (a nice warm well lit room) .  After the baby goes to bed I'll spend a few minutes each night and see if  I can figure it out.
