C4 1987 Corvette Interior - POWER SEATs
« on: January 02, 2021, 05:09:39 PM »
The 87 has 12way electric Sport Seats.

But many years ago the  "Lumber Pump" section on the drivers seat gave up the ghost, dont get me wrong, you could hear it running, but allas it pumped nill (lately I seem to be having sequential pump issues). I removed it and was told by club afficinado's it was "Kaput".

So it went into the "to hard basket" where its dwelled for far too long. Now I seem to remember a member said it was the rubber membrain within the pump, sure enough it turned to confetti when touched, but it could be replaced - however there are no kits available from the States.

It was also stated that a piece of tyre inner tube could be used. OMG  - when was the last time you saw an inner tube, I dont even see them down the beach any more.

Has anyone repaired one of these little pumps, if so, I would really appreciate any feedback, on how, material used etc etc

And yes, I know someone will point out that its usually the "Plastic Bladders" that puncture, these however are still available.

Tubes are available for push bikes, the store might even have a junk one available.

Yes push bike's, never thought of that, now who do I know in the club with bikes of the pedal variety......

Also "MY081" rang to explain the many uses of rubber gloves, some of this information can never be unheard.

Also research shows that US suppliers were from memory expensive, but looking closely they were supplying not just the rubber diaphragm but a whole sub-assembly - total overkill - no wonder the excessive prices.

Anyway with nill available from the US, time to experiment. From googling it appears the C5 has similar issues, but with a totally different design of air pump. Which either fails electrically, shears the vane rotor, or if lucky cloggs up with easy to clean out gunk.

The Pump was supplied by JASCO PROD, INC. SUN VALLEY CA.

The company now appears to be in Oklahoma.

Found the attachment whilst googgling....ummmm would not accept that file ..... try again

The bottom missing half is the precedure - but its simple and straight forward. Looks like "MY081" was on the ball or hand or..
Now "Who" do I know with a 1" hole punch ......ummm...?

 :hi: Good morning Vettech
I have a metric set which will give you a 25mm.

Let me know if you want me to bring it to work at Wetherill Park for you to collect, How's those Bonnet struts going after we welded them?

Cheers :thumb:

How are you O.B one Kenobe.

Yes they are installed and working fine, its funny but the 90 has provision for same, but never fitted, but the main support arm is a gas strut which appears to give better lift and a different method to secure the hood once up.

I just measured it again and 25mm would be great. Old tymers is kicking in - when available for pick up you will need to remind me of the address.

Thanks muchly.

Ok... now I remember  next door to Mighty Mowers.

Depending on the "Doctor" and when he deems me an appointment, hopefully early morning, maybe there 11ish.

Mind you its only for scripts, but it tells you how old your getting when my Chemist rings to tell me he needs to pay his Green Fee's and would I come in early this month to get my ship load of meds.

Thank you.
Vettech.
