Last year a man brought in his pressure washer with a 11hp briggs engine. The push rods were bent. I could not find any problem that would cause the bent rods. Put new rods in and sent him on his way. Washer has worked great for a year now (with lots of hours use). Brought it in today with bent push rods. I cannot find anything that is causing the rods to bend. The engine is a 11hp Briggs Model 216412 Type 0124E1 Code 030306YD.

Has anyone had trouble with these engines? Or have any ideas what would cause it to keep bending push rods.

Thanks for your thoughts

I can't seem to locate a parts break down for the model number you posted, are you sure it's correct?

Are both push rods bent?

Thanks for the reply 30 year. Both times it has been the intake valve push rod. This time the exaust valve push rod had come off the rocker arm. I will double check those numbers, however I used the numbers to look up the parts to order.

Thanks for the help.

The valves are probably coming loose and allowing the push rod to fall off the rocker assembly. The the rod gets under the guide and hangs and gets bent. Make sure you torque the jam nut properly when you adjust the valves and that the rocker arm mtg bolt is properly torqued as well.

Still can't find an IPL for a Model 216412 Type 0124E1 engine.

Thanks for the replies. 30 Year, someday I will learn to read my own writing. Model 210412 Type 0124E1 Code 030306YD. Sorry for the screw up. How long After the initial valve adjustment should the valves be rechecked? Should they be checked after every so many hours?

Thanks for all the help.

usually when you get done putting the rods in, make sure the motor is full on oil, and start it and let it run until it gets warm than shut it off. Than recheck the lash

granted yes oil gets everywhere, but at least you know you did it right

I would check like pyro suggested, only I stick the valve cover back on with one screw to keep the mess to a minimum. After adjustment, I tend to check and adjust every 50 hours or so, I find that most of the time they are pretty loose by this time and in need of adjustment.

How do you torge the jam nut on the rocker arms? You have to have a allen wrench in the screw to keep it from turning. The only kind of torquing tool I have seen is a standard torque wrench. It soes not have a hole in it to put the allen wrench. Suggestions are greatly appreciated.

I use 3/8 drive hex bits, you can use your torque wrench with these.

You can get them just about anywhere they sell hand tools, Harbor Freight has them for quite a bit less then sears.

I'm missing somthing here. The jam nut is around the outside of the adjustment screw. I can set the adjustment screw with the torc bit set ( i have them). But how do I torque the jam nut while holding the adjusting screw so it does not turn when you turn the jam nut, to set the torque?

Thanks

Good question.

I always set the clearance and get it all good and tight, then torque the jam nut without holding the torx screw. Then I check the clearances again to make sure they are still within specs. If you set the gap and get it pretty tight with a wrench and torx bit, it usually does not change much with the final torque setting.

I misunderstood your question, I thought you wanted to know how to torque the adjustment screw, as I know they have a torque setting, but I only torque the jam nut.

Thanks 30 year. Did that and it worked great. Thanks again
