Zenith H2447R 19" Porthole TV

[Crist Rigott]

On to the turret. This turret is massive and very well built. First a photo 'walk around".

Here it is just removed from the chassis with the outboard cover removed.



The aft (motor driven end), if so equipped.



Looking at the side that faces to picture tube.



This is the side that faces forward. It also has the oscillator adjustment tool and drive gear.



Close up of the front end.



A close up of the detent mechanism. Another indication of the quality of this TV.



The aft end ball race adjuster. The turret is suspended by 2 ball bearings. The front end uses a race and 9 "free range" ball bearings, while the aft end uses a thrust bearing. The aft end race can be adjusted in or out to get all the "play" out yet still spin freely.



The front end race.



The aft thrust bearing and the 9 balls for the front race.



A close up of the front shaft where the balls ride.



A close up of the aft section where the thrust bearing rides.



I took this picture to "locate" the actual strip according to the number stamped into the turret.
