Hi,
Happy New Year folks.
Cold here so I thought I'd turn the blower on to raise the temperature in my MkII BT7 from frigid to cold. So far as I can see, there is nothing coming out of said blower. No air, lukewarm or whatever. Now, the motor was running....a) I could hear it and b) I could see the volt meter increase/decrease for a second when I switched it on/off.
So, the question is:- Can the blades become detached from the spindle? ie seemingly, we have the motor spinning but the blades remaining stationary. Make sense? Anyone encountered this one?
Thanks,
Simon

As I recall Simon the blower squirrel cage is just a press fit on the motor shaft. Although I have never come across it I can imagine that it could come loose, particularly if the plastic squirrel cage hub is cracked.
Be VERY careful when trying to remove the motor from the Bakelite blower casing as the "studs" are actually only hex head screws the heads of which are located in hexagonal holes and if forced the case will crack to allow the head to turn. If the nuts are tight I recommend cutting the nut with a Dremel to save the case.

No fan blades. On my BT7, it's a squirrel cage held in place be a nut. I recently rebuilt the blower motor because it was running slow, intermittently, or not at all. Yes, all three symptoms. I sanded the commutator  and sraped down the mica insulation between the copper segments. It works well now. BTW, the motor will blow in reverse despite what other internet resources you find. Google Information about rebuilding the motor.

Also, it is possible the nut for the pull wire for damper at the heater core is loose and the damper is remaining closed.

Thanks for the prompt replies. I think I've solved it. Issue is not at the blower end but under the dash in that b**ger's muddle of cables and wires. I think I'll leave it until I've got time and the energy....
Thanks again,
Simon

Hello,

I am considering updating the carburetor setup on my MkI BT7 to match the
configuration used on the factory rally cars. I have seen photos of the
Rudd Speed triple HD6 arrangement and was wondering if this is the setup
the rally cars utilized.

Any information or photos you could provide would be greatly appreciated.
My goal is to ensure the setup remains period-correct.

Thanks,
Harold

Ken Rudd made go fast parts and sold them under the name Rudd Speed.  They were not used on factory (works) cars.  Rudd speed manifolds were for SU carbs.  Works rally cars used Webers.

In Reading the book "Works Rally Cars by Graham Robson , it is noted "
Triple-SU engines producing about 170bhp were fitted from 1960, then
aluminium cylinder heads and triple Weber carburettors ( with a peak output
of about 210bhp) followed in 1962

Thanks David. I am interested in the triple SU engines. Does Robson book
say if the carbs HD6 or HD8? Does anyone have a picture of the 1960 triple
SU engine?

Hello,

 

I am considering updating the carburetor setup on my MkI BT7 to match the configuration used on the factory rally cars. I have seen photos of the Rudd Speed triple HD6 arrangement and was wondering if this is the setup the rally cars utilized.

 

Any information or photos you could provide would be greatly appreciated. My goal is to ensure the setup remains period-correct.

 

Thanks,

Harold

Harold,

it depends how accurate you want to be. According to Peter Browning's 
"The Works Big Healeys", talking about the rally cars he says:

" The 1960 cars ran with triple 2-in (51mm) SU carburetters on 
individual inlet manifolds...[producing].. 180bhp at 5200 rpm.

The use of triple 45 DCOE Weber carburetters in 1962 improved power 
output to around 200bhp at 5750rpm with a 10:1 compression ratio and a 
high-lift cam"

I would get hold of a copy of Browning's book and go to the back and 
think about how far you want to go!!

Hope that this helps.

Peter

I?m pretty sure they were triple HD8s based on Thelma Seigel?s red early 3000 race car. It was a step up from the Ken Rudd triple HD6 setup and a notch below triple webers. Question is, how much tuning is too much for street use? And how long will even a built Healey six last at 6000 revs, remembering that this is a four main bearing engine and?much of its robustness was based on relatively low (5250) revs? High revs and a wild cam?make their power at those higher revs, of course. Kind of think the BJ8 tune plus a tad extra for perhaps 165 hp at no more than 5500 might be tops for reliable street use, but it all depends?on preferred use (and budget!).?Just a thought ?

All,

the rally cars had different set ups from the race cars as the latter 
ran full speed for most of a long race. The former had less need for max 
speed and more for tractability and flexibility.

As Marcus Chambers told me, you specified a *model* (eg BN7) when 
homologating, but there weren't the same tight criteria that came into 
force much later. Beyond that you could use pretty much what parts you 
had available.

As far as I can work out, a lot of the set up was to meet the driver and 
co-driver's particular preferences (again see Browning's book) and 
varied from rally to rally, even for the same pairing.

Similarly cam profiles could vary between setups. As far as I have been 
able to understand the setup for most rally cars would have been 
somewhat closer to BJ8-style profiles, but I haven't been able to find 
an exact spec and it is widely believed that the works cars build lists 
were all destroyed/lost long ago.

In other words, you've got a lot of flexibility: build what suits you 
and bear in mind modern motoring conditions.

Kind of hard to beat the BJ8 cam for the street,?which was works-inspired and still maintained the low end torque that is the Healey?six?s calling card. Yet even the BJ8 feels a bit soft below 1500 rpm or so?thanks partly to the big HD8 carbs?before pulling you back in your seat. Contemporary road tests also?noted more peakiness with this setup. I imagine triple HD6s would also work well?(and per Hank Leach would have been better than the HS4s?for the Mark II tri-carb 3000s). The rally cars prized back some?low end torque by using the earlier 4.1 rear and even the 4.3 and beyond, depending on the race or rally. Lots of options!

All,

the rally cars had different set ups from the race cars as the latter 
ran full speed for most of a long race. The former had less need for max 
speed and more for tractability and flexibility.

As Marcus Chambers told me, you specified a *model* (eg BN7) when 
homologating, but there weren't the same tight criteria that came into 
force much later. Beyond that you could use pretty much what parts you 
had available.

As far as I can work out, a lot of the set up was to meet the driver and 
co-driver's particular preferences (again see Browning's book) and 
varied from rally to rally, even for the same pairing.

Similarly cam profiles could vary between setups. As far as I have been 
able to understand the setup for most rally cars would have been 
somewhat closer to BJ8-style profiles, but I haven't been able to find 
an exact spec and it is widely believed that the works cars build lists 
were all destroyed/lost long ago.

In other words, you've got a lot of flexibility: build what suits you 
and bear in mind modern motoring conditions.
