Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.

Expert:  Jerry replied 11 months ago.

I don't see that the lifters themselves have any numbers or sequence. Please see attached diagram, thanks.

Customer: replied 11 months ago.
those lifters have numbers inside and they all different diameters. I would like to know in which order they go
Expert:  Jerry replied 11 months ago.

I see thanks, ***** ***** the thickness of them. Yes they have to go in the correct positions. You have to see what the valve clearances are and then measure the thickness, (with a micrometer) to see where each one needs to go.

Lifters are available in 35 sizes in increments of 0.020 mm (0.0008 inch), from 5.060 to 5.740 mm (0.1992 to 0.2260 inch).

Let me see if I have any instructions for that, thanks

Wold you happen to know the correct positions. That's what im looking for
Expert:  Jerry replied 11 months ago.

They are always in different spots according to the valve adjustment that is needed. There are no "set" places for each thickness, I wish there were, thanks

Expert:  Jerry replied 11 months ago.

So actually the valve clearance adjustment needs to be done. Do you still need help with it?
