Hello and Welcome.
Some of you may remember the Giant Attraction restoration I finished back in August of 2011. As it turned-out the original crank that I planned to re-use was bent. At the time the only suitable replacement crank I had on-hand was this generic triple crankset. A crank I suspect was off of Department Store mountain bike. It seemed to work OK, but it just looks kind of trashy. So much so that I pulled it off the market and used it for my part-time rider.
mountain bike the same thought goes through my mind "you really need to replace that God-Awful looking crank-set". So I have decided this would be a good time to make the change. It is still really cold in the shop this time of year. So hopefully I will be able to do some of this work in the house.
Mothers Mag and Aluminum Polish to remove this. It really breaks this stuff down nicely and also leaves a nice finish as well.
pedalS. For this I am using a "Gear Wrench" 15mm open-end / box wrench. The Gear Wrench`s have a typical open-end wrench on one end and a ratcheting box wrench on the other. I have the straight ones with "no lever". Which means when I want to change rotation direction I have to pop the wrench off and flip it over. I really like this design, less moving parts / less chance of failure.
rear derailleur by the bottom of the jockey wheel frame and pull it forward. This takes the tension off the chain so I can now slip the chain off the chain-ring with my right hand and let it rest on the bracket housing.
crank removal tool into the crank. I always start threading this in by hand to ensure it is not cross threaded. You may need a wrench to screw it all the way in. Do not over tighten this, when you feel it is all the way in Stop. You should feel it bottom out when it is in far enough. It is normal to have some threads exposed when it is threaded in all the way.(see pic)
