Ride On Lawn Mower: Black and Decker 241125-00 Fan MM Series Electric Mowers Review

Average Reviews:

(More customer reviews)If you are reading this, you probably need to replace this part.The problem is not that the plastic is brittle (ok, it is), but the real problem is that the cooling fins were designed too tall.When the mower blade hits a root, branch, rock, etc, it will flex up a little - just enough to push these fan fins up and against the motor bolt heads.Did you notice the bolts sticking down, just above this fan?So you can guess what happens when the spinning fan fins bump up against the metal bolts. Snap, snap, snap.When I discovered this on my mower, I was missing 5 fins, with only 3 left.

Ok, here is the simple solution.If you know how to pull the blade off, then just take this part off and remember how the various washers go back on.Once you make this modification on the new replacement fan, you do not have to do this again!You will need to use a heavy-duty sheer/sissors and cut off the top outside 1/4" corner off the fins.Try to cut the same amount and shape off each fin to minimize throwing off the balance.I just cut off the corner in a long triangular shape to create more clearance between the fan and the bolts.Reinstall the fan and washers, and make sure there is at least 1/4" space between each fin and the bolts.

My mower still works great, and I have not had a single broken fin since I've done this.I hope this helps all. (except the parts seller of course, sorry!)By the way, the 4 stars are for Amazon.comThe fan designers get no stars for overlooking this simple design error.
