I have a 1990 Trek 1400 that needs to have its bottom bracket serviced; maybe even replaced. The bike has almost 30,000 miles on it, has never had anything done to the bottom bracket and there is some obvious play in the spindle. While it has been regulated to my back up bike for a while, I would like to see if I could repair it; primarily for the learning experience. Below are some pictures of what the bottom bracket looks like. I am hoping that someone can confirm what bottom bracket I have from the pictures as well as what tools I need and what I can replace it with.
The bike has all 105 components. The cranks are stamped FC-1055. I am assuming the BB is a Shimano BB-1055. Though the second picture may not show it well, there are two flat edges on the lock ring on the drive side. From Sheldon Brown’s website I think this is a standard British/I.S.O. 3-piece BB with a shell width of 68 mm and a spindle length of 113.
From my research I know I need to buy a crank puller and a lock ring wrench. For the crank puller would this one work?
For the lock ring wrench, it looks like I would need: http://www.parktool.com/product/cran...t-wrench-hcw-5
As far as servicing, I going to assume the Trek 1400 bottom bracket cups are probably pitted and rusted. I have looked but I can’t seem to find any places that even sell 3-piece bottom brackets anymore. I plan on trying to clean and grease the BB but if I need to replace the bottom bracket, what are my options? Can I even buy replacement parts for a BB this old? Or can I replace it with some newer technology like a cartridge BB? If so, from where and what would you recommend I purchase?
