After some tender loving care in the rebuild of the Tillotson HL240 carburetor, I was finally successful in getting a vintage Homelite Super Wiz 55 chainsaw purring along (with earmuffs of course because of the power level). It was highly rewarding seeing the machine again flexing its muscle and anxious to start with only one pull. The saw was manufactured (circa 1975) at a time in our country's history when American industry was world class. All the chainsaw components are original (OEM) allbleit there are some minor dings and red paint scuffing from use. However, a difficult to locate replacement chain remains the insurmountable problem, because of its specifications. Since that large size chain is no longer supported by industry, it's proving a problem not easily overcome using local resources.
The individual cutters are stamped with the manufacturer's name STIHL and individually marked 1/2. The drive cogs (shark fins) have the number 6 stamped on each unit. From what I can gather, this represents the .063" gauge of the chain track. This was verified with a caliper. There are currently 51 cogs and 25 cutters in the loop. With the loop stretched out and the links parallel, it measures 25-1/2" overall. Each of the 1" chain spacers has the number 14 stamped on it. The bar is OEM Homelite and measures 18" from the tip to the base of the 3/8" slot. The gear driven drive wheel has eight (8) tangs driving the cogs.
As a last resort, I'm hoping I can locate someone on this site who can point the way to locating a replacement chain. Any suggestions or guidance would be appreciated. Ron (Scranton, PA area) W2CQM@juno.com
