Hi Paul,

I have been  reading dozens of emails about the PSRU gearbox and
looked at the your attachments.

Unfortunately I having been reading these emails, I am getting
slightly confused so I would like to start a short thread to clear
the confusion.

Would I be correct in assuming the PSRU being built by some guys on
this mailing list is derived from  ORG_ROSS_DWG2.jpg drawing ?

There are altogether 16  components in that  drawing. Would I be
correct in assuming that some of the parts are available and one can
get them if they know the manufacturers part numbers ? If my
assumption is correct what are the manufacturer part numbers
corresponding to the 16 components ?

Are they also modifications to the original drawing there fore new
components are involved ?

Thank you Zahid

Yes the entire planetary gear set is available from transmission
repair part wholesalers in the US. One is in southern California
called Slauson Transmissions Parts. Cost about $200 US.

http://www.slauson.com/  One must own a company to buy from them.

Slauson has their own parts numbers. Here is a  catalogue sheet.

Yes there are quite a few suggested modifications.

Here are some.

It is cheaper and quicker to make the housing out of thick wall
aluminium tube.

Hi,

I can't find any information on the Torque meter piston  and Torque
meter cylinder shown on the Input-Shaft5.dims.JPG Where do these
parts come from and what do they look like. Best Regards Zahid

You have to make them.

Paul Lamar back in the USA

Do you have any information on how to make them ?

Zahid Rahman

You use a lathe :-)

It is a simple annular hyd cyl.  Found in all manual transmission
cars in the world. A simple pressure  gage reads out the torque.

Thanks Paul,
I can say now that reduction gearbox  is simple with just some roller
bearings keeping it in position and input/output shafts
and very grateful for that.
but I will need a couple of days on appreciating  the simplicity of this
new device.
Otherwise I just found a company outskirts  of my town who make torque
sensors.

Once again very grateful.
