MGB
bonnet safety catch concerns

There have been a couple of reports of the MGB bonnet
safety catch failing with the bonnet lifting in the airstream and
blowing back over the windscreen. Needless to say that is a very dangerous
situation as the driver can no longer see the road and controlling
the car and bringing it safely to rest is very difficult. Here we
have gathered together links to several useful notes available on
the V8 Website to alert fellow members to the risk of a failure and
highlight two protective modifications devised by fellow V8 members.

Background
to the concerns over the bonnet safety catch
Malcolm
Venables reported a dangerous experience he had suffered with his
bonnet catch failing which allowed the bonnet to blow up onto his
screen. He describes how it happened and the frightening difficulties
he experienced, then recommended the bonnet catch should be checked
carefully as a regular service item. Two additional protection modifications
have been devised by fellow members but they
both strongly recommend that the original bonnet locking mechanism
and safety catch are regularly serviced as a primary protection measure.
Essential bonnet lock and safety catch servicing for an MGB
Regular cleaning and servicing the MGB bonnet release and safety
catch on an MGB and its derivatives are essential as reports of a
few failures of the lock and safety catch leaving the bonnet free
to lift in the airstream and blow up over the windscreen are a real
concern. Here Ralph Coulson describes his regular inspection and maintenance
routine. 050512 V8NOTE447

Modification to avoid a failed MGB bonnet catch
Ralph Coulson describes an interesting modification he has fitted
to his V8 Roadster conversion (Flame Red 4398) to provide additional
protection should the original bonnet safety catch fail.

How do you open the bonnet when the release cable has snapped?
Alan McLean (Damask 1516) in Dublin posted a message on the V8BB seeking
advice on how overcome this problem and Geoff Allen, who worked in
the Rectifications Department at the MG Factory for 27 years, came
up with his routine for getting the bonnet undone again.
