In looking at the various parts catalogs, I see there is a differentiation between engine parts for a 38 216 and a 39 through mid 40s 216. Aren't they the same engine? Why the split? Can someone please explain the difference to this newbie? Thanks! | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | 1937-40 engines have very little different about them. 1937-39 used a four bolt flywheel, 1940-41 had six 3/8" bolts(1942 and later used six 7/16" bolts). 1940 was the first year for the kidney bean shaped oil distributor, held on with three screws. 1940 was the first to use a rear main seal. 1937-40 had dome pistons. There were other subtle differences but that is a start. Here is a list I have compiled with some of the differences.

Was wondering why different distributors speced in May catalogs for 38 and 39/40. I understand it may have had to do with the placement of the generator? | | |
