I need to replace the cartridge on my Delta Seville kitchen faucet. I purchased the part from Lowes (Delta is sending a replacement for free, but I am not sure I can wait). The instructions (see attached) say that a torque wrench with a 1 5/16 six point socket or adjustable wrench is recommended and to tighten at 70-100 in-lbs. If an indicator torque wrench and socket is not available, use an 8 inch adjustable and apply 9-12 lbs of force at a distance of 8 inches. I do not have a torque wrench, and have asked friends but they also do not have one. I do have an 8 in adjustable wrench. I would prefer to not have to buy a torque wrench for this one job. Will the simple adjustable wrench suffice? How do I know 9-12 lbs of force?
