Recently there was some discussion pertaining to the "springy, wavy washers" on the Yahoo "OldEconolines" Auto Group. Someone mentioned that they were called "spring tension washers." Someone else referred to them as "Belleville Washers" and that they were available at McMaster-Carr. Good leads both!
I visited the McMaster-Carr website and after much searching I found the perfect replacements for the "Curved Springs" used on the shifter tube.
I used digital calipers to check the original washer dimensions and a scale to determine the amount of weight needed to deflect the spring.
The original washer is on the left in the photos and the replacement is on the right side.
The replacements that I used are McMaster-Carr part number: 9715K91 and they are called "High Carbon Steel Curved Disk Springs."
The manufacturer is Gardner Spring and their part number is MU750-160. Gardner Spring calls them "Curved Springs." The cost is $10.64 for a package of 10 plus shipping from McMaster-Carr.
The next post to the blog will show the restoration of the steering column and shifter.
