Mi-24 Transmission Transition

In January, we reported that we had removed the transmission from Mi-24 Bord 120 in anticipation of receiving a replacement transmission.

Well, the replacement transmission arrived, but when we set about installing it, we found that even though it had the same part number, there were some differences.

The guys evaluated moving the "front end" from the old transmission to the new, making a hybrid of sorts, but then decided to see if they could restore the old unit to working order.


One of the good things about working with this equipment is, "there is no miniaturization involved". When we opened this baby up, we didn't have to worry about a bunch of little parts falling out. This is real "manly" stuff. Of course it must be strong to act as a transfer case for more than 4,000 horsepower. This picture shows the upper section being lifted from the lower section. At the front of the lower section is where the drive shafts from the two 2,250 horsepower turbo-shaft engines connect.

Unfortunately, when we got inside, we pretty much found what we had expected. Either the transmission was not properly conserved, or the conservation had failed and water had gotten in. In following posts we will detail the cleanup process.
