Sorry if this is a stupid question, but the manual talks about rounding off the installed shim figure before looking up the measured clearance in the table but says shims are only available in .05 mm increments.
So having found 179, 182 and 198 shims in mine (also 200 and 205) does that mean three are 'special' or the OEM from the first build?
A good job I have the jeweller's loupe my old mum used to use for fly-tying or I would never have been able to read them. My digital vernier gauge isn't super accurate but it confirms what they are within the rounding off limits at least.
I'm pretty sure I only need to change one inlet that was significantly on the wide side but was confused by finding shimming more precise than now seemingly available.
The good news is that there is still enough adjustment left on the manual tensioner to get the timing chain tension back to spec.
This is my first ever shimming job on any engine, so could someone double check my work?:
Inlet 1 : 0.23mm 198 shim - so needs a 210
Inlet 2: 0.15 so OK (205 shim in place)
Inlet 3: 0.15 so OK (200 shim in place
Exhaust 1: 0.20 so OK (179 shim in place)
Exhaust 2: 0.20 so OK (182 shim in place)
