I am looking for a Briggs & Stratton crankshaft for my tractor. The engine is a 16.5hp (310707) OHV I/C engine from a craftsman rider. The journal is pretty well scored and was told it was not worth repairing. The Part number for the crank is 690136. B&S web site said that it is discontined and I am debating weather I should just get a new engine. Thanks for any info, Jim
May be outta luck, I checked B&S parts list on my 2005 15.5 hp OHV motor and they don't offer undersized rods. Maybe this practice was so little used they didn't want to go to the expense of having them in inventory.
Next alternative is to look for a good used B&S engine, 15.5 hp or larger.
I'm assuming your Craftsman has a 42" deck.
Maybe 30YearTech or some other experts in this forum will have some ideas.
Your looking at something a bit over $100 for a repair, my local machine shop charged me $40 to grind down my journal, and then then the over sized rod was around $70.. If the rest of the engine is in good condition then I think its worth repairing.
Well Thanks for the info, I am going to pick up a new engine off of the net I founf a good deal on one. I am going to take my time and try and rebuild this one though because it is in good condition otherwise. Thanks Jim
