Re: TA Rear Axle Hubs

The 110 to 130 Ft-lb torque is that recommended by FTFU. It is based on the thread diameter for the desired preload. The outer race should also be preloaded by the installation of the hub. This can require additional shims to set the load path from the hub through the outer race to the bearing carri...

Re: TA Rear Axle Hubs

It looks like the lip seal conversion has been performed on the axle. Although the seal in the nut looks to be missing. From The Frame Up has a kit including replacement Nuts with seals, bearings and shims to perform the conversion from stock (oil Slinger insert) . FTFU Part number is CH201 or CH202...

Re: I think it's TA

Steve, Rob, The TC which was purchased in 1948 (build date October 1947). It was converted to the V8 60 in 1950. At the time there was nothing like torque. The engine is setup in the tune as that was run in Midget race cars of the 40's and 50's. The block is cir. 1938. It has the Clay Smith M3 cam a...

Re: Lucas RF 95 voltage regulator modification.

Ray, Given you are not using the regulator, the condition of the voltage regulating relay is a mute point since the Field terminal should not be connected to anything. If the system was intended to be functional, this condition would leave the series resistor in line with the voltage supplied to the...

Re: Lucas RF 95 voltage regulator modification.

A correction to my last post. I got my relay functions reversed. The normally closed relay on the right shorts out the resistor in the unenergized state (opens to reduce charging at high voltage) and the relay on the right is the Dynamo cutout relay. Open when not charging (engine off) and when the ...

Re: Lucas RF 95 voltage regulator modification.

Ray, The relay on the left (unenergized) should make the connection between A (A1) terminals and the frame through the relay windings. The Relay on the right (unenergized) between the Field and the frame will be the resistor. That relay when energized shorts out the resistor. A good description of t...

Re: Lucas RF 95 voltage regulator modification.

In the configuration stated, the current through the coil winding is the same as the stock configuration supplying current to A terminal. By removing the connection to the E (earth) ground terminal, the voltage buss bar (the regulator frame) is no longer tied to the ground reference through the shun...

Re: Lucas RF 95 voltage regulator modification.

The RF95 regulator can be used for power distribution without any internal modification. The ground (earth E terminal) wires need to be removed. This leaves the buss floating at the supply side voltage. The Field (F terminal) wire also needs to be removed. The Alternator does not use the Field line....
