KE70 Vacuum Advance Pump

[Tham]

Hi,

Does anyone have any spare parts source for a good
vacuum advance pump used in the standard contact
points distributor in the Corolla KE70'S 4K engine ?

My original gave out a couple years ago, so I had to
replace it with the "Century" brand OEM unit from Japan.
This is the only brand available in Malaysia. They are
poorly made and not durable. Firstly, the plastic fine timing
adjuster at the end of the spring is not heat resistant - it
becomes brittle and disintegrates after a few months, throwing
the timing way off. Luckily, my brother-in-law managed to
fabricate a copper one as a substitute, and it has been holding
out well so far.

The rubber diaphragm in the "Century" pump is also not
durable. Mine lasted just about a year. Once the diaphragm
gives out, the pump does not function anymore.

If it gives way again, I'll probably change to a reluctor-type
electronic distributor from the salvage yard. I'm currently using
contact points with Silicon Chip magazine's high energy
ignition unit (Dick Smith kit).

probably better off trying in the wanted parts section in the classified
