Bell Housing Strengthening Bracket

For now, I lumped all the pre-war cars together, I would LOVE for there to be enough demand to split it into groups (hint...hint, post here about your pre-war Singer)

Bell Housing Strengthening Bracket

Not all Singer unobtainium is exotic…take this unobtrusive yet vital part that is often missing.

It’s the gearbox bell housing strengthening bracket. The counterpoint to the casting on the other side created to cover the starter motor shaft and pinion. The two give strength to the bell housing that has to support the gearbox and take the torque of the drive to the rear wheels. The Singer design has no rear gearbox mount and the gearbox literally hangs off the alloy bell housing.

The result of a missing bracket is usually a cracked bell housing and sometimes a sticking clutch!

It’s been many many years since I’ve seen one of these and it was with great luck that the Canadian Singer Skunkworks team found an original amongst the piles of parts that came with NASOC President Paul Bouchard’s 1935 Le Mans Special Speed Model. We've used that to create a batch of new ones to fit to our cars, so if any of you need one, now is the time to let us know!

Here's the first being test fitted to CSSW Alumni Barry Phillip's '35 Le Mans Special Speed when I was last over working on the car with Barry.

Barry needed to notch his bracket to clear where bolts have replaced rivets, otherwise it was a perfect fit!

Another update on the bracket project...

My bellhousing arrived back from the welder and some time was spent dressing the repairs. He said besides the arched crack right where the missing bracket should have been, there were a host of stress spider cracks around the casting which needed attention. We bolted the bellhousing to a thick plate to avoid distortion during welding.

The shiny area of the housing on the side between the two lugs is the main crack repair. Once dulled down, it will be almost invisible.

Next job was to pull a rear engine crossmember from stock and check that the bellhousing was a flat, true fit and that the new extra-strength 'skunkworks' bracket fit properly.

After a bit of fettling, all looks well!

The next step is a new clutch cross shaft and proper bushings in the bellhousing. The wear is surprising here as the steel usually gets grooved badly rather than the alloy! The lubrication in this area is marginal and the clutch cross shaft should really have been drilled and tapped at each end for a grease nipple and then cross-drilled.

Gee, Phillip,

This looks fantastic!

Can't wait until these are available 'commercially'. Count me in, please. I would love to mount this as part of the drive train to make sure as much power gets to the rear wheels as possible, and away from the more fragile aluminium bits.

Thanks for your and Barry's work on this bracket.

Cheers,

David
