| Post subject: | Replacing bearing on Bosch Colt |
Hi all, As anybody ever replaced bearings on a Bosch Colt? Mine is starting to vibrate more than normal and having them changed by a tool shop is pretty expensive. I know I can get the bearings themselfs for quite cheap though, so I'm wondering if it's something I can toy with, or if I should leave this to preofessionals. Thanks for your inputs! |

Google is my friend! Found this: http://www.contractortalk.com/f40/bosch ... ost1131523 Now I'm kind of thinking of just replacing the bottom bearing. Isn't it the one taking on the most load? |

well...for all of the trouble it takes to disassemble a tool I've always opted to change all bearings possible when one goes out...they don't cost all that much... best of luck to you...I've been finding lately that apparently most all of the bearings in tools (made in China) are total cr@p, which at best don't last all that long, and at worst have severe run out issues when brand new...for instance read the reviews on the LSxx16 makita saws...I have had direct experience with a total of 8 of this series, and all but one had blade wobble (bad spindle bearing) right out of the box...knowing this fact I decided to spend $280 to totally rebuild my 14 year old Makita LS1211 when it munched its second worm gear of its life...and as noted above I replaced every single bearing in the system along with the armature and its associated gears... |

I took a Colt apart once to address minor issue. Can't recall if the bearing was pressed on. But getting it back together was a bit challenging. I agree with above, if you are going to replace one bearing, replace all. Brushes too while you are at it. And if you are serious, replace the collet with one if these: http://www.precisebits.com/products/equ ... s_nuts.asp Mike |

There is a Canadian distributor for Precise bits - http://www.cutncarve.ca/ I don't have experience changing bearing in the colt, but I have a Bosch router on my CNC and usually have to replace the bottom bearing every 6-8 weeks. I find the I can usually change the bottom bearing 3-4 times before the top bearing starts to go. Josh |

Thanks with the feedback guys! The top bearing needs to be pried out, and I don't have the tool to do this. And it seems to me the top bearing must be less worned than the bottom one, and I'm not prone to fixing what is not broken. And Josh comment goes in that direction too... According to the forum thread I posted (Contractortalk), the bottom bearing is not pres fit, so I should be able to do it myself. So thanks again, and I'll keep you updated. |

Alain, I would still consider that precision collet. At the very least, read the info on that site. Mike |

I'll echo what Mike says about buying the precision collets. They are well worth the money. I have them on my CNC router as well as my router table, and I'm gradually purchasing them for my other routers. I've used and own routers from every major manufacturer and have seen some pretty bad factory collets. The precision collets help to extend bearing and cutter life while also giving improved performance. Josh |

Had not thought about that. But it would make sense that bearing life would be extended while using that collet. |
