FRONT AXLE CONTROL - BENTLEY.

We have had trouble with the nuts securing the axle control to the axle coming loose.

On 4-B-IV during the 10,000 mile run in England, the strengthened axle, N.Scheme 3749, was fitted, in which the bolt size is increased from .375 to .4375. These have not come loose.

At the moment we do not want to standardise this axle, as it has a different transverse pivot lean.

We recommend however that the larger bolts should be put on production as soon as possible.
