Sumo Gambling

Recently baseball gambling by Sumo players has been repeatedly casted, then how about Sumo Game gambling itself by baseball players ?
Now is the time to cut off giving them national tax because of the reason that Sumo is Japanese National Game, better oblige them to be an independent group financially.
Their internal condition, the Sumo field head players are almost occupied by foreigners, this is the point to be put an emphasis on, difficulties to keep it as a National Game in Japan now.
Though we Japanese was completely defeated by US in WW2, we've won US National baseball game twice, those were sweet feats on earth.

Frontal set back error

Recent research has proved that the frontal set back adjustemet must performed at first in wheel alignment adjustment and any other trial with set back error would not efective nor in vain because of uneven frontal self centering effects on both sides that has much to do with caster trails.
The adjustments are so accurate as to micrometer level and seconds angle value.
The caster trail error is observed on hill climbing up and down because the caster angle(included angle) changes according to the road inclination.
Experimental situations exist here and there if self concentrations are scattered for researching result.

Work on Compacts

Inquiry to the factory proved that many troubles occured in drive shaft joint on NCP10 Vitz historically, also re-called.
The reactions on the problems by the dealer are just replacing the parts, no way to disassembling the shaft joint. I'll open the boot on the joint to know the cause of the small but occaisional knocking noise right outer joint. Probablly new grease application to the ball joints will solve the problem.
Replacement of fuel pump will be the following task before noon today on EP82 Starlet.

Suffer

The suffer caused by some good intentions to improve some situations is to be seen in any case. For example, Exhaust Gas Recirculation(EGR) emission control system on the vehicle is so designed to cause incomplete combustions by inletting some amount of exhaust gas leading to burning at lower temperature. The purpose is reduction of poluting emission gas.Then, what'll happen if this dirty exhaust gas circulation is stopped by some method ? Naturally the burning temperature rises up and cooling liquid temp also up, leading to high utilization rete of electric cooling fan, following the lack of charging in lead battery is the result.

Rubber & Lubricant

In order to keep the performance of any machinery at ultimate condition, keen capability to know the actual symptoms utilizing 5 senses sometimes 6th one is required. The lack of lubrication on moving parts means metal connecting wear leading to backlashes. Many rubber parts are applied to keep grease oil as boots shaped parts, gaskets for prevention of leakage and insulators for noise and vibrations.
Especially vehicles have many of them, so continuous checking is required by the users as is enshrined in the Road Vehicles Act.

Future tasks remained:

*BC7 SUBARU Legacy
Wheel hubs greas up and rear drive shafts boots inner and outer replacement.
Brake master cylinder inner cup replacement.
Frontal brake calipers replacement into 4 pods.
Frontal lower arms replacement into alminum construction.
Wheel alignment and geometry re-construction.

*EP82 TOYOTA Starlet
Fuel pump replacement.

*NCP10 TOYOTA Vitz
Frontal right side drive shaft replacement.
Weel alignment and geometry re-construction.

*SXE10 TOYOTA Alteza
Frontal cambers re-checking and thrust angle reconstruction.

*XH200W OPEL B-Vectra
Frontal suspension spring rubber upper seats and upper supports replacement after shock absorber replacements.
Rear shock absorbers replacement including rubber parts.
Geometry and wheel alignments reconstruction.
Rectifier and voltage regulator in the alternator replacement from original one to Astra's.
Radio antenna booster re-checking.

Modify autos

To modify a tall passenger car into sporty condition is no meaning. Tall shape itself has disadvantage for physical stability, no way to escape from this truth and fact.
So the vehicles in normal condition as factory finally decided design is the vest balanced one.
Because professionals did it depending on their responsiblities by their own risks. Ordinal vehicle users neve exceed even a piece of their capabilities.
For example, compliances on axle construction, the designers and engneers pay ultimate attentions to the balance between them.
Only a small rubber bush replacement affects the total ballance.
The same is said onto the designing of a drivers chair. The raplacement into 3rd parties sport type means the realization of the lack of axle stability and motor mount deformations. Concequently any replacement into defferent one means destruction of total compliance balance.

Knocking noise

XH200W B-Vectra driven by my friend proved the cause of knocking noise is just from shock absorver on rear left side, sitting myself on rear seat the fact was so clear.
Disassembling the construction would show more precisely, the climinal may be the piston guide wear or dumping rubber deformation, this is today's task.
Lateral arm joints were replaced previously, but another reasons exit.
