Hi there,
Does anyone have any spare metering heads that I could borrow a pressure shim out of? I want to get some made up as you can't buy them anywhere now. I need some for my car and I'm sure others do, so a few to bring along to eurotec would be handy I'd think.
I just need to borrow one shim to get the internal and external diameter, and then make some up with different thicknesses. What thicknesses would be it be worth making Nick?

Cant Ken Mills sell them to you in packs of 10 ??? Thought that was his minimum order now ?

I think Alastair spoke to them and they can't supply them anymore.

Im wondering ....cant ... or wont .....?
whichever it is, I have a couple of volvo metering heads and I think I have 1 spare shim.
I would say 1mm shims would be just fine and could be made from standard metric washers, but the centre hole would have to be drilled out.
I will get the dimensions for you Dan if you think you could get some made up.
I haven't bothered getting anymore as my fuel pressure is now set at 5.5 bar and Alistair had my last 2 0.5mm thick ones.
Book setting is primary pressure to 5.1 to 5.3 bar (checking range is 5.0 to 5.5
All cars have been around 4.7bar.

Hi Mike
It was definitely cant, and also I tried a direct Bosch stockist they all say no longer available.
I wonder if making them is a go-er?

I think mine was 4.7 when you checked it last year Nick. I would like to get it up to 5.5ish with the new exhaust on now. Roughly what is the pressure increase per mm shim?
If you could measure a shim for me Nick that would be great. I can make them on the lathe with a piece of stainless bar, turn it to the required diameter, drill it out then slice them off.

Hi Nick, did you get change to measure the ID and OD of the shims?

Cheers for that Nick. I'll try and get some made up for eurtoec. Also can I book your services with the pressure tester? Beer will be available :wink:

Of course they will be stainless :wink: Nothing else will do.

If you can get the washers made, JRG wants to do the same check with his fuel pressure as well, if we enough washers then we could set our pressures right before Eurotec, provided someone will let us borrow their tester!
I know how many washers I need to get mine roughly right
