The company I work for, that being Mining Technologies International, can rebuild your old buckets, or build you new replacement buckets for loaders and excavators of all kinds. We have several bucket lip styles and ground engagemnt tools to meet whatever needs you have. Price may not be the cheapest on the market, but you will get quality product. MTI has manufacturing and rebuild facilities in the US and Canada, but ship globally.
They can do simple lip replacements with striaght, spade, easy fill, and toothed lip systems, using hard plate or cast lip systems. Or they can make and replace the worn out plates in your bucket, add wear strips, shoes and buttons, teeth, replace and linebore the pin bosses and bushings, etc. so when you get your bucket back it is in excellent reliable condition.
If anyone is interested, either go to MTi's website below for contact info, or feel free to shoot me an email and I will get you in contact with the proper persons.
