Maintenance today

Visiting Osaka SUBARU Tezukayama this afternoon for checking my BC7 complaining linger recently. The special engineer having served as WRC SUBARU mechanic found out several failures after driving and lift up inspection, thermostat activates so often may be caused by narrower space of the valve, frontal differential side seal oil piling especially left side and frontal differential gear drain plug oil piling causing oil burnt smell after driving. About the side cover oil seal replacement, I will try when drive shaft DOJ or DIJ boots would be replaced at the same time in future, not so urgent business.

The the essential problem on rear transfer clutch was not so critical, but very initial stage of wearing sign, sooner or later operation would be necessary, but not so difficult available for me, he said.
Also he said the inconvenience of the clutch did not be carried out by pouring Dexiron 2 TOYOTA genuine ATF about 5L in 8L. Only the replacement of internal multi plate clutch 4 ot 5 pieces would recover the original good operation.
About the choice one of them, BE-BLE 3L model and BC7 initial generation US model, he could not determine, because they are located in the extremes polar.

Point surfaces smoothing holding 0,40mm gap adjustment, ignition timing at BTDC 10 degree and adequate air volume control screw on Solex 34PICT3 carburetor had recovered smooth operation of VW air -cooled AD motor in 1302 Super Beetle this after noon. These kind of adjustments on mechanically dynamic parts should be periodically performed every 5,000km use. Trans-axle gear change becomes easy to do after smoother combustion has attained.
