Image1.1.1

2.) If part number on camshaft is 260-1890, no further work is required.

3.) If part number on camshaft is 139-0538 then camshaft is incorrect and must be replaced with correct 260-1890 camshaft.

4.) If rear cam cover is not accessible then remove valve cover and look for a stamped "J" around the cast journal material that is between the exhaust lobe for cylinder #3 and the camshaft bearing journal. If a cast "J" is not visible in this location no further work needs to be done. Refer to Image 1.2.1.

If a "J" is cast in the material in this location then the camshaft is the incorrect camshaft and should be replaced with correct 260-1890 Camshaft.
