Main shaft (A) maximum permited clearance 0.10 mm - subtract from the reading taken previously using the feeler gauge.
Lay shaft (B) add the maximum pre-loading of 0.20 mm to the reading taken previously by the feeler gauge.
Second lay shaft (C) add the maximum pre-loading of 0.30 mm to the reading taken previously using the feeler gauge.
Remember also to calculate the thickness of the new circlip on the shaft by measuring the difference in size between old and new components, then adding or substracting the difference from the thickness of the old circlip.
I have uploaded some pages from the manual. This should add some smooth Alfa Romeo precision to your gearbox 😃
