OEM 7mm Lash Caps

[stevesingo]

Does anyone know if there is an OEM that uses 7mm stem diameter valve lash cap where they can be ordered by size, something like 0.05mm increments?

Getting my own ground to size is a little tedious and it would be easier to have a stock available.

Thanks for the help.

What size range do you have?

[stevesingo]

FWIW I'm looking at in the region of 3.95-4.05mm on the inlets and 3.55-3.65 on the exhaust.

Do you know what skirt length you need? I carry a few for my own use if you're ever desperate, but I tend to have them with shorter skirts for my use.
There is a supplier in East Mids somewhere, they carry blanks or will grind to whatever you need, if you want their number I can dig it out over the next few days.

I forget the skirt length, I'll have to measure. I was hoping there was an OEM that produces them in 0.05 increments.

What sort of depth can you grind off blanks without losing hardness?

Correct, under bucket shim. PITA for doing valve clearances.

I think my problem is that the Arrow lash caps I have been using are 5mm thick, unground. In order to get to my desired 4mm and 3.8mm region I am grinding off too much material and therefore losing the hardness. This is why I believe I get increased gaps after only a short period.

The reason I was looking for EOM in 0.05mm increments is that the OEM lash caps will be hardened at the specified size.

The Arrow lash caps have 2.4mm depth.

0.05mm increments up to 3.50mm and then 4.00 and 4.50mm. No 0.05mm increments in the size range I'm looking for.

I'll speak to Arrow tomorrow and ask their advice.

Spoken to Arrow and they say the lash caps are through hardened and can be ground down to 1.50mm from their unground 5.20mm as supplied thickness.
