My compactor ram is stuck in the down position.I took the side off and found that the white plastic gear(model #882699) was broken in half. I tried grabbing the chain to see if I could manually move it by hand but the chain is very tight and would not budge…is the chain supposed to be that tight or is something stuck? My question is if I put this new gear on and the ram is stuck, will it break the new gear? Im not sure how to manually get the ram back to the up position.
