I'll be watching progress with interest Yabert. Bolt is a great donor, such a shame we don't have any over here in the UK.
Actually, by law, some places it's more aggressive than that.Vehicles are declared a total loss when repair costs exceed the value
Perhaps, but a $3000 car which has $2000 of damage is a total loss anyway, because there is salvage value in the damaged car, and administering the repair (including a rental car in many cases), so the net cost to the insurance company would likely exceed the replacement value of the vehicle.Actually, by law, some places it's more aggressive than that.
For example, "2/3" is often the rule. $3000 car has $2000 of damage or more, it's done.
Hmmm. So I went hunting for a regulation. Can't find any. Was told (few years ago) by my insurance company it was a provincial regulation, industry standard just about everywhere, and that all insurance companies have to follow it.A 2/3rds value rule sounds like just an insurance guideline (rather than a law)
No. Sadly, control and programmation stuff isn't my strength.were you able to pull CAN-logs? for example to re-use a complete battery?
I can see that the Bolt's power steering might not be needed to keep the Bolt drivetrain bits working, but what's the plan for steering boost?Not needed - the power steering...

Is there some mechanical engineers who can help me / confirm me that a shrink fit coupling assembly will work for my situation.
The situation is I have to fix a 26mm Chevy Bolt cardan shaft to the 28mm Westy cardan shaft. Both shaft are steel (unknow type)
I plan to rework an A513 1-1/2'' x 1/4'' wall DOM tube to link both cardan shaft together by press fit and add a Tig weld at each end after (hope picture help to understand).
Based on tribology online calculator, in my situation, the interference fit itself can pass over 3000 Nm of torque. The Bolt have a torque of 266 lbs-ft at motor shaft and a gear ratio of 7:1 for 1862 lbs-ft at cardan shaft or 2527 Nm.
Ok, thanks.Hi Yabert
Looks good to me
If I understand correctly, you are talking about a loose fit (0.001'') and all the torque will be transmit by the weld.That is essentially what I am doing.
If I recall correctly, cold drawn seamless mechanical tubing would be more likely to be true than drawn over mandrel... and it is actually seamless. This presumably won't be inexpensive, but you don't need much.The only things I would add: DOM doesnt have a tight callout for straightness, so inspect your piece.
On your collar: if you drill at least two holes through coupling and weld down to the inner tube the joint becomes as strong as the inner tube. Required procedure on aircraft tube structures
