Thought I broke my old one
I thought I had broken the one on my 30+ year old mower and bought a replacement. I discovered a video while changing out other older parts that needed replacing that showed I had only taken it apart to to point of cleaning, oiling and putting it back together after I had bought a replacement. It works great after a little break in period to loosen it up. Part wasn’t much, but the special removal/installation tool cost about 1 and 1/2 the price of the part if you don’t have one. I’ve restored my 1987 or 1989 MTD to look and run new after buying a new Honda push mower that made 3 trips to the shop in the first 3 months of ownership before I parked it in the shed and broke out my old original Briggs and Stratton motor on my MTD and started restoring it to new.
