My son has a Mongoose mode 180 and his bearings are bad. He said he needs a bottom bracket set, but I'm not too sure if this is what he needs or if it's something else. Is this the right one?Any help would be appreciated. My son has a Mongoose mode 180 and his bearings are bad.

Bottom bracket installation requires specialized tools. So even if you are able to find the propper size BB you would still need to buy the tooling. That's not very cost effective for something you're only going to do one time. I would weigh out the cost of taking it to a bike shop against the price of a new bike. Good luck

No. BMX bikes typically use a different style similar to this: http://www.amazon.com/gp/aw/d/B000IQBBKO/ref=mp_s_a_1_1?qid=1417644028&sr;=8-1π=AC_SY200_QL40

No way for me to know...It is best to take it to a bike shop. They can measure it and suggest a replacement. It should run no more than 25-30 dollars and about 15 or so to install it. It will be worth your money to do this because if you do it yourself you will also need a bottom bracket tool so you probably have to spend about the same or a little more than if a bike shop does it for you. Call around and get 2 or 3 quotes.

I first started with a bearings upgrade, which totally changed the feel of the board, then I threw on a set of Gullwing Sidewinder II Trucks, I don't recommend those trucks in particular due to having two kingpins, and the board has a big disadvantage with wheelbite with these trucks, and a bit of speed wobbles. I suggest a set of Paris' or something of the like. First, I'd start with bearings, and just work from there:)

I don't know and you don't need to know. All you need to know is bones bearings are the best bearings on the planet period. I'm sure if you go to their website you can find answers there.

Personally, I've had the same problem. I would suggest getting new bearings (I prefer Reds), and wheels (Sector 9 is the best in my opinion). Your trucks should be fine. Oh, and just to keep your bearings moving properly, invest in some speed cream.

My set of these came with adapters that enable you to put them on either of the two types of mounts. I put them on my Mongoose 29 from Walmart. They work a lot better than the standard Promax that came on the bike. One thing that might be a negative is that on my bike the wheels kind of warp to the side of the disc when the brake/brakes are applied.

the bottom bracket refers to the axle that the crank arms attach to... the crankset comes with everything to attach it to your frame except the wrench to tighten it

My first suggestion is to read all the previous answers on the UN55 before you attempt to replace your bottombracket assembly. If you can remove the spindle, look to see if the specifications of the spindle are embossed on the spindle itself. For example, my Shimano spindle has specifications of 68 - 122.5 embossed on it, the smaller number is the bottom bracket bearing tube width and the larger number is the actual spindle length. Then select the UN55 sealed bearing BB that is the closest to your measurements.

there should be a label on the bottombraccet itself with all the specs on it. if you cant find the info on the specialized web site the simplest is to remove the bottom bracket and take the info from there.

This is a front steering hub bearing assembly. The rear axle bearings are completely different. I will say this, I'd been using cheap NAPA bearings in my front hubs which my truck would eat up yearly and I was constantly changing. Since I put in the Timken bearing I haven't had to change a front bearing.

buy another one. :) I contacted the company for replacement bearings and they never responded at all. I think you're on your own with this one

You'd be better off purchasing just the turntable bearings, or lazy susan bearings!! They're much cheaper than buying this Lazy Susan (which works great, by the way) and taking it apart!! :)

No, you need MTD part # 984-04253-0637. This is for a left hand drive and the bearings won't line up. There is one listed from MTD for yours for $88 that comes with 2 bearings right now, that's a solid deal!

The bearings consist of two sealed cups that thread into the bottom bracket on each side. The crank is attached to a hollow shaft that slides through these cups. This design is called Hollowtech II by Shimano. I'm not sure about the width, as it may work for a range of widths. I used this to replace a 68 mm English threaded BB on my 2008 Specialized Hard Rock XC Disk and it worked out well. It comes with plastic spacers that allow you to adjust the chainline (distance between the seat tube center and middle chainring). I believe all of the spacers must be used, but you shift the cranks side to side by changing the number of spacers under each bearing cup.

I had difficulty with the entire set-up from beginning to end. As far as the posts, I originally had that problem because I had the posts in the wrong insert. Once I switched them around, the posts were fine. It was the backboard that was the worst - popped off and hit my son in the face, knocking off his glasses. I ended up returning the entire set. Good luck and be careful.

Those are the bearings and they shouldn't be falling out. You might want to contact Marcy. They are good at making things right. The down side is you will have to disassemble the uprights to replace the part.

@HankCostello: Your spindle is part of your bottom bracket. 133mm is quite long. So, continue use that BB, unless its worn out. The Shimano Alivio crank is JIS square taper. Your spindle will have to also be JIS if you want to use the Alivio crank.If you want to replace your BB with a Shimano: I used a Shimano sealed UN-55 Bottom bracket 68mm in mine with this crank. The ISO threadeing are either 68mm (standard) or 73mm (oversize) The UN-55 bottom bracket is available in 107, 110, 113, 115, 118, 122.5, 127.5 mm spindles when ordering.
