I just removed the camshaft out of a 1919 engine. All of the cam lobes are the same width. I want to replace it as it is badly worn with a reground camshaft. Is the thrust washer kit required. Mac's website says that the thrust surface is removed during the regrid. Does this mean they cut the first lobe narrower?
The regrind takes the back of the lobe lower than the diameter of the cam shaft, removing the thrust surface for the front bearing, still the same width...
Unless you're on a very tight budget, why not put in a new Stipe 250 or 280? Why lose power and economy for not spending $350 more?
There was somebody selling a rebuilt engine/transmission earlier this year for $6000 and the cam used was a regrind!
Stephen -- You can use a '26-7 reground cam with the matching front cam bearing without the need for the thrust washer kit.
