T34


Opened circuitry of reverse gear tail lamps must be connected today, because feel I some inconvenience parking at night everyday.
This is caused by the repositioning of ignition coil and the wiring was connected on plus terminal of the coil, now about 50cm length must be compensated?
New wire from fuse case to coil that positioned on the left side would be prepared.

The price down, from 1250,000yen to 700,000yen of Karmann T34 is interesting for me now, negotiation with some VW shop was done yesterday. My price is 500,000 yen. How it would become of?

Disassembling carb.





Careful inspection proved that there are some critical deformation on automatic choke modular coupling connection. Too tight fitting prevent the module rotate so smooth as to adjust adequately.
This deformed distortions on the coupling surface must have brought ill tightening torque, misunderstandings of construction.
Former engineer or just a laymen must have given too strong muscle actions? Though the screw are the same as another metal to metal constructive portions, these 3 screws play a part of not tightening but exerting some adequate pressure on the round spring choke module holder. So the torque here is at the rate not to be loosening by vibrations and by the thermal cycles in the engine room.
Distorted round shape inside here made it difficult for the module to rotate in actual adjusting situation, this inconvenience obliged me to adjust by grinding convex portions manually, as for myself, being relatively good at this kind of fine adjustments.
The errors on this Bocar 34PICT3 carburetor would be corrected with careful checking and adjusting from now.
The fundamental problem on this device reported in every Web site, backlashes in throttle butterfly supporting center shaft formed with the case on both sides is checked.
Some lateral displacement of butterfly was observed when coming to most closest position, being relatively easily solving problem by inserting some adjusting sim there.
The history and biography of this second handed 34PICT3 is not so wrong except the deformations on the choke module coupling.
The vertically lined splay holes 4 in total that is the same as Solex 34PICT3 as widely reported.

The replacement of ignition coil from Lucas Gold 7 ohm into Bosch original one with 3 ohm resister value awakened the performance of VW 1302 Super Beetle this afternoon.
I realized the importance fo coil first stage resister value matching if the different parts may serve admirably.
Nervous and sensitive difficulty in the motor performance disappeared throughly and now feel I very comfortable in 1600cc AD motor's performance.
Next, the spark plugs must be checked to know the combustion stare.

Resister value


Tracing the memory when I replaced genuine ignition coil into Lucas gold coil, I felt some change of condition and the discerned the difference of exhaust note.
The difference of 1st stage resister value 3 ohm to 7 ohm must have brought the sensitive and nervous situations and have made it difficult to continue the ignition timing in stable condition.

Knowing that the ignition coil used in the Transistorized system has lower resister value below 1 ohm, this is not favorable for point signal system distributor and the additional resistor to sum up to 3 ohm must be applied in series connection.

But in case of excessive resistor value, no information was found in the Web site. How about connecting parallel connection of additional resistor to sum up 3 ohm?
In case of new parts, Bosch Blue Coil with 3 ohm resister value from the beginning is favorable, so written in the Web information.

Roughness?


Consideration on the problem that I must adjust point gap so often on VW 1302 Super Beetle led me some possible conclusion, the roughness of the cam surface touching with the cam lifter plastic material. The touching surface here must be shinny finished like a mirror with minimum slipping resister, otherwise cam lifter of contact point mechanism construction easily worn in short period of time?
No lubrication has something to do with the wear if the cam surface is rough like a file.
Polishing with some micro grain polisher would be performed after careful checking, though the distributor set on the AD motor now is new genuine Bosch with vacuum advancing mechanical actuator?

Even Google has been attacked by some Chinese hacker, CNN so told this morning with Mrs. Clinton's comments.

Wire harness

The length of wire harness in the engine room of VW 1302 Super Beetle would be adjusted adequately, the reason was caused by repositioning of ignition coil in original place following the air conditioner compressor removal.
Additionally the wiring of backup lamp is not connected for lack of length.
Today's task would be concentrated in electric wiring in engine room and lead battery portion covering plus terminal.
Description later:

Written in the evening:
Over 250km distance on highway was covered today as high speed running test driving in '71 VW 1302 Super Beetle. I came across to the heavy rain fall as to being drenched to the skin if I was out side of automobile, no water invasion into the cabin nor strange function on generator were observed while driving in the shower.

Very comfortable exhaust sound was heard all the time, because contact point was precisely adjusted and also ignition timing.
Point surfaces were not parallel each other, so filing adjustment method there was necessary.
The maintenance inside of distributor is just like a periodical ceremony for fully mechanical controlled machinery.

Wear progresses relatively quickly on the tip of plastic in the contact breaker construction, so I have some idea to replace the plastic material into Polyacetal Resin? Easily deformed by continuous hitting so quickly? Or deformation occurs because of the heat from the crank case?
Changing physical property on the point may be somewhat interesting on earth?

Remembering that the ball joint on tie rod end was not changed and the replacement parts are kept with NIB condition?
Let's do that, replacement of tie rod end parts on both sides.

Wheel alignment would be checked again at that time and following adjustment, rear cambers, total toe and thrust angle would be adjusted so firmly as to go straight if fingers untouched on the steering handle.

Cooler or Steering action?

Single fan belt is used to operate not alternator but generator and cooling fan designed fitting on the extension of anterior potion of generator centric shaft.
So only a belt is to be observed in the air cooled VW Beetle if additional equipment such as an air conditioner is not burdened.

In case of air conditioner fitted air cooled Beetle, tail height down is inevitable because of the over 30 kg weight of the equipment.
Suspension springs and shock absorbers are not designed under such as extra burdening with the air conditioner.
In the engine room on the other hand, the occupation of 3 dimensional spaces by the huge compressor, supporting bracket and connecting hoses,
it's very inconvenient for servicing, especially #3 spark plug tightening is a half impossible task. Anyway all the handling and servicing in engine room are hindered considerably.

The weight of the heat exchanging devices are not ignorable and the important steering reaction is much spoiled on earth.
According to my experience on the point, the attitude changed completely immediately after the removing of the cooling devices removal from my VW 1302 Super Beetle. It was exactly like this, the dull Beetle became to run about freely as same as young Ayu released in clean and clear water.

Reaching the end

The generator in VW 1302 Super Beetle has come to be free from care for rain fall after the setting the brush service hole cover in position. But for this small plastic parts, heavy rain fall attacked on the commutator and triggered charging disorders. Oxide thin film to cut off fluent current flow was relatively easily removed by applying finger pressure on the brush holding spring.

Almost of restoring of this Super Beetle has over except rear hub bearing replacements, body painting procedure.
AD motor 1600cc and trans-axle are healthy in the best condition at 30,000km, both of them were Microflon processed for the purpose of reduction of friction loss, resulting comfortable success.

Also seat covers for driver's seat must be prepared because of stitch breaking in some parts. Already finding out the parts in the Web site, at 1,8000yen, expensive?

Watched I "Rongo" by a famous ancient Chinese genius in NHK educational channel this morning. Useful knowledge were introduced to replace the hardships into the subject to overcome with pleasures.
Refreshing my brain may be necessary to read up through the famous article, "Rongo".
