45 mb engine number question

Post by lowell » Fri Nov 25, 2022 10:02 am

I’ve got my dads 45 mb and was wondering if the engine is also late war. Mb542471 is the engine number

Engine looks like it should be a mid January 1945 casting. Look for a 1 - x or 1 - xx on the passenger side of the block towards the rear of the engine

Hi,

According to the skew graph in Nabholtz, that frame should have an engine around MB575xxx.

Hi,

The casting date from just below the starter motor would be more helpful.

It’s in MM-DD format.

Hi,

1-17 is the key!

Cast Jan 17th (1945) - so that ties in with sjalberts estimate from the engine number.

Based on the data I have the original engine would have been around MB585xxx. So based on the casting date the engine you have is WWII but not original to the Jeep. I don’t have any hood number info in the date range of your Jeep.
