OK, vibrator advice, anyone? No, no, stop sniggering........

[chippie51]

We've been going through some of the spare bits we have kicking around the hangar and have come across a few of the following:

"Vibrator, Aircraft Engine Starting. AN4181-1, Type VJS 24A1, 27 Volt 1,7 Amps. American Bosch"

Anyone have any idea what aircraft this would have fitted? Would be nice to see them go back on an aeroplane.

Many thanks,

George

the AN in the part number means it is a standard part,so it could have been on many different planes.

Thanks Matt, would be nice to identify the application of this part as it would be great to see them go back on an aeroplane and be of use to someone.

Got one on the Bell 47, supposed to help start it. Doesn't seem to make a lot of difference...

The have them on Stearmans as well.

We have 4 on the Douglas, I'll check the p/n when I get home..

I think the BT-13 must have had several.

Ours are VJR24-B5 Vibrator, Induction.

Why would a BT-13 have several? We only have one per engine, connected to the left mag on each on the C-54.

The FG-1D Corsair uses the VJR24-B5X

Why would a BT-13 have several?

insert giggle here....

Wasn't the BT-13 called the Vultee Vibrator?


The canopy provided the nickname “Vibrator.” When the cadet throttled back on descent and at certain rpms the canopy would come alive and would shake, rattle and roar in its tracks, very loud, very distracting:Thus, the Vultee Vibrator.

'.....please excuse the jerky handwriting....' very old punch line to a very old joke
