I just remembered the effect of Microron, this material has special affections onto the metal touching surface to reduce the friction. According to my own experience, the Teflon coating material was effective if used with motor oil.
I just determined to apply this material into the ball recirculating steering gear box on VW 1302 Super Beetle, no replacement parts is available only on right handled model, in addition to relatively weak basic mechanical design of steering linkage. So the wear of ball nut gear box means some critical physiologic phenomena to finish it's life only for right handle designed Super Beetle, the critical weakest point. Then this is why I chose 1302 with only 30,000km running.
I thik it a promising treatment on important gear box to apply Microron, though I do not prefer to apply 3rd party materials on the automobiles, this is one of the exception.
The devices to be obtained are followings:
Timing light to ascertain the ignition timing on VW Beetle, also the BTDC of EP82 TOYOTA Starlet would be checked. Here remember the word, Before Top Dead Center, BTDC. For point-less and computer controled Starlet, futher use of the device is the most unlikely, only for the use on oldest 40 years Beetle. To tell the truth, I threw the timing light exhibiting on YaHoo auction few years ago, I never imagined the day would come like with old VW Beetle now.
The battery on Beetle was checked yesterday, exactly the same as Opel Vectra's one, D terminals and relatively big sized, additional charging would be performed today.
Big sized airconditioner compressor prevents me from accessing into deeper part of the engine room of Beetle, in very near future all the system would be removed throughly, hoping some improvement on downed tail, unacceptable sagittal view, nose up and tail subducting style.
The possibilities of two steering centric position on BC7 SUBARU Legacy are the followings:
The straight running position and the most stable steering position are different, so some right side adjusting is required in order to keep straight running, on flat road surface my BC7 Legacy would start to left side running gradually if I release hands from the steering. In this situation, let's think about the reasons of the phenomena on physical property.
On the frontal axle, the degree of negative camber of right side exceeds to the left, the right inclination is more than the left one. The negative camber values are already firmly fixed at minus 15 minutes on both sides.
Setback conditions are already measured and ascertained exactly the same length.
On the other hand, the wheel base difference apparently exits, left side 1mm shorter than the right, this means the swung rear end phenomena causing left side tendency, I think the most suspicious error point. After the corrective adjustment of this swung rear end error, residual measurements would be performed at any rate, rear negative cambers, standard value 40 minutes, and toe-in value, 1mm in total and thrust angle 0 degree as near as possible.
Just writing like this is relatively easy but actual work requires truely desperate efforts on earth, the fighting with the physical properties of rubber and lubricant materials, movability, deformability, viscoelasticity and their hysteresis.
The checking all the time while measurements are carefully necessary, opening and releasing all the compressed and packed internal factors and forces.
