[Tigers] Bolt size for heater valve <-> pipe flange?

[Ron Fraser]

I see a #10 UNF x ½” listed with the valve but not sure if that is correct.

Sunbeam Parts Lists are available online.

Check the OD of the threads – a table I have indicates #10 UNF 24 TPI  OD = .190”

 

For British cars you need UNF tap and dies – SAE tap and dies will cut metal because they are slightly different.

 

If you have extra bolts – I like to cut grooves down the threads to make a thread chaser to clean out the threads.

 

For any stuck bolts use penetrating oil or ATF, let them soak overnight if needed.

Hope that helps

Does anyone happen to know the bolt size for the 2 bolts that are used between the valve itself and the pipe flange (with the mounting bracket sandwiched in between, photo below)?

 

The look like maybe 12-24, but I don’t have a tap or die to confirm that ...

 

It appears as though the leak in mine is caused because the seal between these two has perished, but so has one of the bolts!  Going try replacing it with a small donut ring to see if that cures the issue.

 

Cheers in advance,

 

Rick
