Ant-post inclination

Steering circle surface position is important because the driving position, especially anterior-posterior inclination is decided affecting on the stress applied the adjacent portion of thoracic and lumbar. Also the surface has something to do with the winker lever function.

Additionally in relation with the seat back inclination, the operability of switches on cluster surface. So the change of steering surface position involves many relations.

Setting frontal total toe value at in-1mm on VW 1302 Super Beetle is the priority task today before going out for a driving in nice breeze to Northern part of Hyogo Pref.

The reporting on the result after upper two treatments would appear in the evening:

Moving the steering circular surface only 1cm backward brought me a great improvement of driving upper body position on VW 1302 Super Beetle today. I have no pain nor fatigue feeling on my back they have been suffering me for long time. I have recognized the importance of 3 dimensionally adequately suitable steering wheel position.

Though BC7's steering position had been corrected as 10mm backward following the SUBARU improvement reports for a newer model, 10mm more backward might be better, experimental trials must be performed on this point.

Frontal camber value was corrected on the left side, minus 24minutes to 34min.and 30seconds that's the same value as the right side one.

Remember here the camber value must be adjusted under the condition of same toe direction, in another word, camber value must be adjusted in combinations with the decided tore direction, so both of them should be performed at the same time together.
This complicated procedure makes the alignment setting difficult for the engineers.

And the total toe was set at 0,8mm finally, because the negative camber setting automatically produces camber thrust to inside considerably. Less value may be possible, decision of the total toe would be later after the actual running test.

Continuous running over 6 hours caused strange noise that had not been discerned before, the origin of the high frequency noise was from the DC generator's rear bearing!
Pooley side bearing was possible to access for lubrication, if the pooley assembly was removed from the centric drive shaft.

After applying chrome molybdenum splay grease without replacing bearing, successfully the noise disappeared finding out no mechanical backlash on cooling fan mounted drive shaft. Finally I was released from the anxiety to be suffering from the lack of lubrication leading to bearing seizure.
