Amorulove TOOGOO Bike Bicycle Cycle Crank Puller Bike Tool

Located on one end of this tool is a socket that fits the crank arm nut...The other end fits inside the crank arm and there is a wrench to turn it located in the package. See the small photo...This is not the ONLY crank puller I own and NONE of my others came with a crank arm nut remover...In fact with my other puller I had to buy a socket wrench just to remove the crank nut BEFORE that puller would work...Not buying another tool to make this one work means this one is much cheaper since you can simply use it as it comes to you and it does the job..The black end screws completely off.. You MUST remove that inorderto slip the other tool upon the flat parts of the socket..The red handle wrench that comes with this has a hole in one end..Put that on the flat spots of the shiny part and screw the black part back onto the tool..NOW leave it that way and simply move the red handle wrench back and forth to which end you are using at the time. This is simple. It's not an expensive tool but it works well and is low in cost..Screw the black part in first with the center pin far enough out it will NOT hit on the end of the inner part of the crank. When you have the big black part FULLY inserted into the crank arm slowly screw the shiny part inside the black part..Once it's tight stop, using a rubber hammer or a hammer with a block of wood between the tool and the hammer bang it straight on pretty hard. Screw the shiny part in some more and if the crank does nt start to come off bang it again. Warning DO NOT bang hard NOR directly on the tool with a hard faced hammer or you WILL damage the tool..The idea of banging is to break the arm loose..This tool WILL pull hard and as you screw the inside part into the black part that puts pressure on the arm to release it. You may need to soak that arm in oil over night if a light tap don't work.. You CAN break any tool if used improperly..if you use wisdom and this tool you should be able to pull cranks all day long without a coffee break..For more info contact me at chiefredelk at gmail dot com..Good Day, Chief.

I used this to remove the pedal crank arm on an exercise bike. It's one of those tools that you won't use often but if you have the need, this works well. My only caution is that I assumed the socket for attaching a lever to turn it was a square so you could use a breaker bar or ratchet. It's not. It's a hex so you need an Allen wrench. You can, however, get away with a wrench on the lower external hex. That's only practical if the crank is not too tightly set. But, you won't know that until you try to take it off.

Don't let the price fool you. This is a great product and is probably the most economical crank puller you can buy. The included wrench is paper thin and hurts your hand if you really have to reef on it. I would suggest a rubber mallet or using an adjustable wrench if your cranks are that tight. This tool will outlast me. Simple, effective, affordable. For a specialty tool that you rarely use, this is the way to go!

I am not sure what this strange picture is supposed to show, but the black nut has to be screwed into the crank first, and this chrome bolt is then screwed into the black nut to push the crank off the axle. Nevertheless, the thread of the black nut didn't match the one of both Suntour and Shimano cranks. It took me probably 15 attempts, lots of WD-40, and some force to get this black nut seated properly. It also took some force to screw it in completely (the metal nut looked undamaged, so I probably messed up the softer alu threads of the cranks slightly). Also, this little wrench that comes with puller is useless. It's about 2" long and is far too short for a good grip. I didn't even try using it since it looked very flimsy. I used an adjustable wrench instead. So, while this puller worked so-so for me, a slightly more mismatched thread would have rendered the tool useless for me. Since I didn't read about this problem before, and assume that these threads are normed for Shimano, Suntour, ..., there might be some 'tolerances' during the production of this crank puller. So, I would not buy it again or even recommend it to anyone how removes cranks on a regular basis.

Simple, gets the job done. Even with my whole toolbag, I still required this little guy to fix my bike. As soon as I screwed it in place, it was a cinch to use; got the crank set right off. Hopefully I'll never need to use it again, so I'm glad it was so cheap!

This was a good value, as for it's durability I think it should hold up under normal use. It also is fairly easy to use. Yet I am unsure of if this is a quality tool, as I feel like there are better versions of this product with higher levels of quality. But will work fine for most bike riders, who do not have to have the best tools.

This product was a lot higher quality than I had expected. I'd recommend this over other options. First things first, my crank ended up getting stripped out from this tool, but this tool was not at fault for it. This tool managed to strip out my crank without getting its own threads stripped out at all. I used it on an old Walmart bike I had laying around just to try it and it still worked fine! For my crank, I ended up hammering it, beating it, squeezing in light oils, and applying degreasers to it with no avail. I plan on just biking on it and hoping that the repeated stresses will cause it to pop off eventually. Just hoping it won't kill me when it does come flying off.

Please, read the reviews with photos showing how bad this tool is made. I wish I had. My weekend plans are shot because I got this tool in the mail and thought I'd be able to work on my bike, then ride. Nope. This tool removed one side perfectly, then bent itself all to heck on the second side, and stripped my crank in the process. It is seriously, a poorly made tool. This coming from a guy who usually buys Chinese made tools because I'm not a power user. Basically, this is the one and only crank I'll likely ever remove in my life, so why bother spending a lot on a crank tool? Yet, an extra 3 bucks would have given me my weekend back. I'm such a schmuck.
