Title: Engine/box/clutch weight
Post by: MikPowl on 03.05. 2025 11:35
Does anyone know the approximate (or accurate!) weight of an A10 lump complete with gearbox and primary drive?  I'll be shipping one soon and expect I'll need to know the weight. Don't have any suitable weighing scales myself.

I can tell you from personal experience it's kin'eavy..
I hate to think of the costs of shipping that.
Could you not do the old "weighing yourself with and then without you holding the lump on your bathroom scales", trick?

My wife's kitchen scales are now (very thin) toast - expecting some trouble on that front.

The BSA data books give some of the weights

For 1961 for example

Gearbox with sprocket = 22lbs or 10 kg

Iron head A10 engine with mag and dynamo = 106lbs or 48.2 kg.

Ally Head A10 engine with mag and dynamo = 97 lbs or 44.2 kg

Where are you shipping to/from?

Thanks, Julian, Exactly what I was looking for.  Shipping within the UK as a box of tired bits to be reborn as a glorious example of British engineering.  Have given up the long-held delusion that I'll ever get around to doing this myself.

I can tell you they make a spectacular crash when they fall off the bench onto the floor  *eek*
