Perhaps better photos clarify the situation. One shows the brake off (disengaged)/ The other shows that with the brake on. The arm cocks off to one side and doesn't contact one of the pucks at all. I cannot find any service manual. Could the spring/ linkage assembly that holds the left / top of...

Yes, the spacer is installed. I did use aftermarket pucks. They are full thickness (measured against the unworn edge of the used puck). The pins do extend. When the brake is fully engaged (and with parking brake on) The pin on one side is barely touched, the other one makes no contact with the arm.

Yes. I will do that later. Thanks.

John Deere D100 new to me. Brakes could not be further adjusted with center nut. I replaced very worn pucks. Still no breaks. The arm that should press on the little adjustments pin does not touch the pins regardless of adjustment. More adjustment just causes the pop clutch reaction. I am...

My JD L100 lawn tractor stalled on a flat the other day, just stalled but accompanied by a hard to describe noise sort of like something spinning down. After that I got only a solenoid click. I tested the battery at 12.2V, but under load only 10.2. On Sunday, it is easier to replace the battery...

That is exactly what I did, Star Tech! Did your repair hold up well?

Star Tech! That was it! You taught me something important! Now it's running great except for the smoking! Think it's time to adjust the carburetor.

Thank you for the responses. I am pretty new to small engine repair. Bertsmobile1 - Thanks for the tip on checking on the intake valve guide. TDC firing stroke, meaning both valves closed and piston at TDC, correct? Regarding the exhaust valve I just repaired, the valve guide broke free...

By the way, the push rods are intact, straight.

Hi, On the exhaust valve, I have repaired the valve seat, lapped the valve, replaced the valve seal and head gasket. Set the valve clearances. It started right up but It started but immediately blew out the valve seal because I did not understand how to seat it firmly. Lots of oily smoke. So I...
