briggs starter gears

Recommended Posts

I had 19 hp twin v briggs motor that shear gears on that starter all the time.It got to the point where once it was stared it would run all day for fear of starting it again.Stupidly this went on for years.Changing gears all the time.The last I bought a new bendix complete assembly.Same result!!!!!Now I was determined to fix this once and for all.Make a long story short you can not see the drive when engaging because it's under the flywheel.I took the motor out,drained oil and turned it upside down.I discoverd the the drive was only one third of its posssible depth to the flywheel.I left one ear on the starter alone and elongated the other to act like an eccentric.I left about .010 depth from gear tooth to flywheel in the engaged position.Two and a half years later......PERFECT!!!!Not all my electric start briggs equipment had the same problem but two other did but not as chronicly.I did the same for them.I'm sure the starters are made in Japan and for their own use and consumption(honda or robin) the machining is more accurate but for briggs and tecumseh is less than could be desirable.

You also need to support the shaft on the roll pin style starter, otherwise a difficult removal can cause the shaft to bend and cause a similiar problem with gear engagement.
