… the NO-BS reply from JT Garwood > page 171 > 1951, at engine number1-0379470 and at ch. number 1-0313829, the engine crankcase was now made of a new aluminum magnesium alloy formula, known as electron - the crankcases were darker, beginning with 1951 models - they were not as shiny and bright as before - everything else, was left untouched for 1951...
… note on page 34 - 1945 engine - the magnesium aluminum alloy crankcase held the crankcase rigid in it's 4 insert-type main bearings - there were no separate cam bearings - the case was hardened, at this point - early engines, through 1950 were lighter in color then those used in 1951 and up - z _________________ 5/50, pastel green 11G - SOLD

Those numbers are the last VIN/Engine #s for 1951 so this sounds incorrect since it would be the beginning of the 1952 models.
The beginning of 1951 would basically be the numbers from Progressive Refinements above.

Thanks,
So, based on this information would the "new" cases have been Dow 7 coated? |

Googled, Dow7 - Much like DOW 19, the DOW 7 is also a chromate chemical conversion coating. Chemical conversion coatings, when applied to magnesium, have chemical reaction which results in a thin film being formed on the magnesium surface. DOW 7 also contains the toxic chemical hexavalent chromium (aka:Cr 6+) - give your Dow7 a try, then report-in your findings - z _________________ 5/50, pastel green 11G - SOLD

It's a PDF so you can print it out if you prefer a hard copy.
In this case I would argue a PDF vs. a hard copy is superior since you can search it with the Find command.
Search on "crankcase" and you can jump right to that entry.
I post this info mainly for others to be aware of as it can be useful. _________________ How to Post Photos

Everett. Thanks for all the hard work that you go through keeping this great site and all of its resources available to all. It's a pitty that some don't appreciate it. _________________ Chris

Ted2 I bet you wish you hadn't asked
It's good to have more than one point of reference. For me PR is great web based info for quick access anywhere and Garwood is a better read.
Not everyone has access to Garwood so credit to Zen for doing the digging when there's a query, as there's no search function in the book. |

… rechecking things to hand write a correction entry, I was looking in 2 places, at once (old age, setting in) - Garwood suggests the new Electron formula introduced at engine number 1-0266000 and chassis number 1-0220472 these numbers were at the very beginning of 1951 - my apologies to JTG and everyone else...
