4k 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).
