question Fv 432 / Abbot external run up of power pack

[robin craig]

So, one can run up an FV430 family power pack external to the vehicle.

 

A few questions on doing this.

 

If you wanted to test a spare 432 pack could you do it without removing the one that is in the vehicle?

 

If you can not, why?

 

Can you run a 432 pack external to an Abbot?

 

Can you run an Abbot pack external to a 432?

 

How can you test the function of the gearbox when doing this with any confidence?

 

I know that is a load of questions.

 

 

Regards

Yes you can run-up a 43 series power pack externally from the vehicle without removing the vehicles own power pack. Stand the pack facing the vehicle, inspection hatch open disconnect the various leads and fuel line from the vehicles own pack and attach to external unit. Check everything is connected properly and when satisfied you are ready go for a start using the vehicles on-board starting panel. Not sure about Abbott cross 432 going to be dependent on the service connection and there location on the pack. Gearbox, with the short prop shaft removed there is no reason why you couldn't drive the box but what are you looking to achieve. Baz

Yes to all the above, the electrical connections are identical but you may have to make some adaptors for the fuel lines as I'm not sure about the union sizes.

 

You can make sure the gearbox output shaft goes round in each gear but that's about it. Remember to disconnect the prop shaft unless you want a mangled oil tank and cables.
