[Healeys] Healeys Digest, Vol 17, Issue 98

[JSARCH]

Bob,

I installed a Denis Welch lightened flywheel in my 1962 BT7 back in 2013. Overall, I like it but there is one small issue. If you stop on a steep incline, you may not be able to continue up the hill without backing down and getting a running start. That happened to me early on when I was driving around on some back roads in the Santa Cruz mountains. I never experienced that problem with the factory flywheel.

Thanks for the input Craig. I'm still debating the flywheel; hopefully, my path will be apparent when I get the box out.

I'll be checking the bell housing bolts, and the input shaft for wear. I already have the OD operating shaft 'quad rings,' I got them as soon as I saw Roger Moment's article (long story about the seller).

Re:  Lightened Flywheels

 

Hi Bob:  I absolutely love the extra power (perceived or actual) in my Healeys with light flywheels.  My BN1 has one from DW that weighs about 12 pounds and I'm using DW's damper on the front.  The car has an upgraded crankshaft and BN7 gearbox, so maybe that's kept it from flying apart.  My BN7 w/BJ8 cam has an alloy flywheel I got on eBay that I think weighs about 20 pounds.  It runs smooth as silk with no ill effects.  I still can get occasional run-on though, with lower octane fuel. 

 

On the gearbox oil leaks, check the lower bell housing bolts which, at least on the side shifts, extend into the gearbox and can leak.  Also, "Quad Ring" OD operating shaft seals are available from AH Spares, part 0VD185MS.  I haven't tried them yet, but it seems like they would be an improvement over the single O rings generally used.
