proteus Posted July 30, 2006 Posted July 30, 2006 Finally got the engine (Briggs #191700) on my tractor running perfectly today. After half the lawn was done the coil died. It was less than a year old so I was able to get a new one and was back to mowing when all of a sudden she died again. This time the pulley on the flywheel wouldn't turn. In my haste to do all the work on the tractor I failed to keep enough oil in the crankcase. What a dumb[img]/club2//attach/UCD/censored.gif[/img]. I removed the engine from the tractor, pulled the flywheel and carb, drained oil and split the engine in half. The gears all look fine and there's oil on everything. There was about a 1/4 C. of oil in the crankcase. So where did it seize? Did the cam fuse itself to the engine? How do I fix this. Do get a piece of wood and try to pound the cam back down and see if it will break free? Did I do permanent damage? Is this fixable or did I kill this engine?
wilm169 Posted July 30, 2006 Posted July 30, 2006 not enough oil ussally would say rods seized, but the cam might be also , try dropping the rod caps and looking at them.
proteus Posted July 31, 2006 Author Posted July 31, 2006 If the rod seized, how do you get it out? I'll be taking the valve cover off today to further inspect. Where do I begin? Is there something I should do first in order to know where it's binding? Or, should I just start loosening visible bolts and try to take parts out to find out what is sticking?
PatRarick Posted July 31, 2006 Posted July 31, 2006 The rod is the most likely probability. Get a manual to help you along. This is the one you'll need. It's available at any Briggs dealer. http://shop.briggsandstratton.com/BShopProductPage.asp?CatalogID=56B2B9B0-283C-11D4-8886-00B0D0203414&MECID=100&SessionID=385E483A-41E5-4A94-8E13-1381E09DC5C1&CategoryID=&lrid=1&ProductID=56B2BB53-283C-11D4-8886-00B0D0203414 Pat
proteus Posted July 31, 2006 Author Posted July 31, 2006 Thanks for the link. I have the newer Briggs manual that covers my model. Doesn't help much. Not like a Haynes manual. I guess I'll just have to poke around and see what I find. I hate going into this without a plan. Probably going to waste time on areas I shouldn't be focusing on.
proteus Posted July 31, 2006 Author Posted July 31, 2006 Boy am I lucky. Turns out there was just some carbon that flaked off the valves and got caught in the piston cylinder causing the piston to bind. It was jammed pretty good so I put some vice grips on the crank, drizzled some oil on the piston and used a breaker bar to get it moving. Cleaned up all the bits of junk I could find and then I could turn it by hand. I thought I really killed this engine and I got my wakeup call. I'm going to make sure I check the oil on this much more frequently.
