Task Description
20080/1 E 98-12
Calculating setting dimension "B":
Setting dimension "B" is basic bore "a" in cylinder head
(see Tolerance and Wear Limits List 05-3832 or
05-3832a) and pilot diameter "A" divided by 2.
Example
"a" = 60 mm
"A" = 14.55 mm (pilot diameter)
"B"= a + A
2
"B" = 60 mm + 14.55 mm = 37.28 mm
2
Release locknut (2) and set micrometer to dimension
"B". Slightly raise rotating tool, place micrometer on pilot
and using rapid adjusting screw (1) set cutting tool to
dimension "B" and tighten locknut (2).
Note
It is advisable to set cutting tool diameter 0.1 mm
smaller for the initial material cut.
Insert horizontal stop screw (8) until it contacts housing
and tighten clamping screw (9) to prevent horizontal
stop screw (8) from turning.
