Excellent replacement which fixed the issue I was having. Great videos illustrating how to implement the fix. Well done BCH! Great job with the video. Helped me get the printer disassembled, broken gear removed, and new gear installed. Heating the replacement to ease installation was a winner!

Thank you Kevin for this very detail video. The pump in my printer was completely clogged. Your video was very helpful. Luckily, I didn't have to completely disassemble the pump. One step before completely disassembling the pump I was able to flush out the clogs inside the tubes. This video is a valuable tool along with print head cleaning, tools and other maintenance tips. I would recommend this video to anyone that has a clogged pump. While the printer is apart inspect and clean other areas. Thanks again Kevin.

This is actually my 2nd CISS system. The first was from a vendor preassembled and filled for plug and play with a Canon 2720. After installing it, I realized that the 4x45ml capacity wasn't clearly stated and is much too small. I then swapped out the tiny Black 45ml tank with a BCH 500ml tank. Easy. 45ml colors are sufficient. I can run the Canon for 4 months. More importantly I learned how a CISS is assembled and it's operating characteristics. Today I ambitiously added a 500ml BK and 3x75ml Color tanks to my Brother MFC-5930DW refillable cartridges. I have to refill the cartridges every 2 weeks. Now I should have at least 4 months between refills. BCH had all the parts to build my CISS and explanations on how the CISS bottles work and their positioning.
