SUNBEAM 1000HP GEARBOX RESTORATION AT THE NATIONAL MOTOR MUSEUM

[@humphrey4976]

Lots of wise men rebuilding this. Good work.

[@MartsGarage]

Great stuff guys, thanks for showing all the little details. Good luck with the whole 1000hp project. All the best, Mart in Solihull.

Quite a gearbox very robust looking. It must whine quite a bit with those straight cut gears.. This is a very interesting series. I thank you for your desire to share with the world.

Looks like a giant M/C trans. In great shape throught. I would have oiled the parts on reassembly tho,,,Keep goin',

[@robgeotim]

Strange that the reassembly is being done dry? We always used assembly lube to ensure all went smoothly on first startup.

[@kukipett]

Yes that's not a good practice, but those two gentlemen are doing quite a sloppy job, installing bearing with a hammer like some redneck crazy mecanic!

I am not a mechanic, but I have some machining experience and have bee through abespoke gearmaining shop in Sheffield to see some of the processes involved in making large gears like these. I did notice some edge damage to two of the gears in this box, Not that nasty but did some of the teeth need dressing to smooth them - or would that be counterproductive?

[@Wreckitralph54]

When the car was making its record passes back in the day they had issues with 2nd gear engaging. That’s the result of it. I doubt this car will go into 2nd gear again since 1st gear takes you to 70mph.

Nothing like an old socket to drift a bearing in.

Sliding pinion gearboxes always show chipping and rounding of the tooth leading edges - even the most skilled driver is going to crunch the gears in a crash gearbox occasionally, especially when getting used to the particular vehicle - and this, of course, was a one-off, and a pretty fearsome one at that. In fact, I was struck by how pristine the gears in this were, reflecting the relatively few miles it actually travelled - you should see the state of the teeth in a bus or lorry gearbox which has done hundreds of thousands of miles!

[@lancewhite1477]

The gear at 8:17 is a bit chewed.

[@keith0alan]

Cheers me up to see someone at that level using an old socket to drive a bearing in.

It's not an F1 box is it!!! More agricultural

[@GrahamSimons]

Use of adjustable spanners?..... tsk tsk!!!
