Hi,

 

I have taken a reading between the FICD valve terminals on the IAA valve and got a reading of 25ohms - I think I read somewhere that it should be 75ohms - is that correct?

 

BTW getting the IAA unit off is a complete b****

and as for the Air Reg - the bottom bolt is blind and I am having extreem problems getting to it - any ideas anyone?

 

Next Q! Anyone have an IAA unit for sale - 4 A 1990 JAP TT?

 

Cheers guys and best regards.

FICD should be approx 22-25 Ohms

AAC should be approx 10-11 Ohms

Air Reg should be approx 75 Ohms

 

As for removing, try a short extension bar on a socket, a flexi/UV joint is also nice here.

 

When you refit it, junk the hard water pipe and replace with a 6mm silicone hose, makes the job a ton easier!!

 

And finally, yes i have a spare one somewhere, ill get back to you.

Thanx Ollie - sounds like mine are ok - FANTASTIC.

 

I will give them a good WD40'n whilst they are out - and then proceed to remove the remaining skin from my knuckles as I go back in for the Air Reg - lol

:dance:

 

Cheers again.

... I will check the reading on the Air Reg (75ohms tomorrow as well).

 

Cheers Ollie

Air Reg is easy once you have mastered the IAA unit ;) just remember to bin that annoying metal pipe bracket! You can completely dismantle and clean both the Air Reg and AAC for a good clean with wd40 - like so:

 

When i did this i found my Air Reg spring to be broken, so worth a check.

Hi,

 

Just to close this thread -

 

With many thanks for the advice provided - I managed to get the Air Reg off in about two minutes - FANTASTIC! All cleaned and ready to go back on... ;)

 

My AAC measured @ 15ohms (11ohms stated)

My FICD @ 25ohms

and my IAA (Air Reg) @ 80ohms (75ohms stated)

so I assume these are all within reasonable thresholds of variance for their purpose.

 

Please let me know if you think otherwise as I intend to put it all back together tomorrow (weather permitting)! :rofl: ;) ;)

 

Thanks again.
