how to convert degrees to ft.lbs.
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

how to convert degrees to ft.lbs.

I'm trying to figure out how to convert degrees to foot lbs of torque. I'm trying to torque something down and my wrench on ly goes down to 25ft. lbs. and the sped. calls for 20ft. lbs and an additional 60degress. I would appreciate any help possible thanks. :?

Torque the bolt to 20ftlbs and THEN turn the wrench EXACTLY 60 MORE degrees. That is a torque to yield seting and has nothing to do with ftlbs.
They sell little plastic degree wheels that go over your ratchet/breaker bar that are about 2" in diameter so you can watch as you pull and get it exactly on 60 degrees. Auto parts stores carry them because many of the new vehicles require you to change head bolts because they ARE torque to yield bolts and that is the ONLY way to torque them correctly.
Many of the newer engines have torque to yield rod and main bolts too.
Some heads would have torque specs like:
1. torque all bolts to 20lbs in sequence
2. turn all bolts in sequence an additional 45 degrees
3. turn all bolts in sequence an additional 35 degrees
NOT the same as
1. 20 lbs
2. 35 lbs
3. 50 lbs
go purchase the little degree adapter and (new bolts if it calls for them), do it correctly.
