[Healeys] JB8 Stuck Heater Valve

[Peter & Veronica]

...you probably need something a bit more abrasive to lap the 2 together – I used Solvol chrome polish. Coat the taper with Solvol & lap into body of tap.

Cheers

G’day

 

Which reminds me!

 

In the process of getting the Healey Duncan going I disassembled, cleaned and polished the brass ‘tapered plug’ drain tap and it looked very pretty against the gloss black of the engine. One problem is that it didn’t seal!

 

So out it came and with much physical action with a cloth and Brasso the tapered joins were polished. Then when assembling it received the gentle hammer treatment in the hope that it would seal. It didn’t!

 

In the end I removed the tap from the BN3’s engine and used that which worked perfectly.

 

The tap fitted to the Healey engine is more ornate that fitted to the Austin-Healey but apart from more work with Brasso I’m at a loss at what to do.

 

Thanks

Hi Mike,

Th valve that you are working with is actually a "taper plug" valve. 

I just freed up 2 of them this morning for the 100 engine that I'm building.

I have found that a gentle tap on the small shaft that extends below the spring is usually enough to loosen the taper and free up the valve.

Don't hit it too hard or you will damage the brass shaft. 

If that doesn't work you have to remove the split (cotter) pin, then the washer then the spring. That will expose the end of the taper which when tapped with a hollow punch will drop out.

I have read in the archives about all the handles broken off the heater valve (controls coolant flow to the cockpit heater).  

My handle is not yet broken off.  I can't get the valve closed with reasonable force.  Any hints or suggestions?

Thanks, Mike
