 |
|
Can anyone tell me info on what the main differences are in the crash box transaxles from early splits? from like the war year kdf up to like 1950? I thought that the very early ones were aluminum and then at some point they switched to cast with maybe an aluminum nosecone; can anyone elaborate?? what changes were there and when?? I can't find any info in the forums...
Thank you. |

| The switch from alu to magnesium was in Feb 1951 - same time as the engine cases. |

| thanks for info; so all transaxles pre 1951 were aluminum case? do you know changes that occurred regarding alum nosecones vs cast steel? im looking at a transaxle with kdf logos on the side, with an "H" in a circle above, and a "17" stamped below cogwheel; and has a steel nosecone.... |

Im going to have to disagree with your info. I have verified that two other transaxles i know of that both clearly have verifed serial numbers from 1950 are magnesium cases, not aluminum. One was reported original to the car. one serial number is May 1950. I also have seen a restored 49 chassis with a magnesium trans. So it seems that info of a feb 51 switch over is not accurate. So I would like to know when the change occured.
Thanks for any info someone can provide. |

Thanks for the info Mika. So it appears that some were beginning to be made in new material starting in March 49, and final full transition by the end of April '49.
Thanks again!
PS. Any info as to the use of steel nosecones on the early aluminum transaxles? were they all like that? |

| I have an original May 47 gearbox, which has the yellow/brown painted steel nosecone, and so additionally they must also been produced after the war, or maybe using up old stock? |
