I’m ready to install the rear axle collars on my 640. My ford manual states “Heat it to black red” and place a pipe over the axle and onto the collar to hold it till the collar cools and seats. Since I don’t have a torch I am going to take it to school to the ag shop. The ag teacher is a young pup and like me has not done this before. I did read that too hot will ruin the collar, and of course too cool and it won’t go on.
I watched a you tube video where the guy puts an axle collar on a Ferguson but he heated it till it looked very bright yellow-orange.
I found this chart, but it might not be much use vs real world applications.
C----- F---- Color
400 -- 752 -- Red heat, visible in the dark
474 -- 885 -- Red heat, visible in the twilight
525 -- 975 -- Red heat, visible in the daylight
581 -- 1077 - Red heat, visible in the sunlight
700 -- 1292 - Dark red
800 -- 1472 - Dull cherry-red
900 -- 1652 - Cherry-red
1000 - 1832 - Bright cherry-red
1100 - 2012 - Orange-red
Any suggestions from those experienced?
