Hi listers
I've searched the archives but cannot find anything relating to this.
Could I ask for your help, please?
We were out enjoying the BN4 last week until there was a brief shrieking
noise from under the bonnet (hood) when changing up a gear, followed by
a distinct rubber burning smell. Slowing to 50mph cured the smell and I
kept the revs down for the rest of the drive. Coolant temperature did
not waver from 190 degrees so I suspected a generator bearing failure.
Back in the garage I checked things out. The water pump turns freely and
so does the generator, with no evidence of bearing failure in either. I
also put the battery on charge - the charger switched from 'charge'
after only 30 minutes, so the generator appears to be OK.
Cleaning the fan belt (a simple wipe with a rag - no evidence of oil or
carbon contamination but the front end of a Healey isn't the cleanest of
environments) and re-adjusting it has stopped the noise for now.
However, as the belt was tight before - about 0.75 inch sideways
movement on the belt between crank and water pump, plus you could turn
the radiator fan but not the generator by hand - I therefore concluded
that a new fan belt was required.
Now for my queries:
1. Anyone disagree with my conclusion?
2. How do you get the fan belt between the starter dog and the chassis
cross member? (Jack up under the sump?)
3. Any preferences for fan belts sourced in the UK? The existing one is
toothed and sold under the 'Unipart' label, which means it could have
been made by any manufacturer!
Any help will be greatfully received!
Regards
Paul
