Upon removal of valve spring and valve stem seal, the wear on valve guide can be determined in installed condition by moving valve stem predominantly cross\u00adwise in relation to engine.<\/div>\n
As a reference value, a max. wear of approx. 1.2 for 1000 km (0.12 mm for 100 000 km) should be assumed.<\/div>\n<\/div>\n<\/td>\n

However, this value does not apply to upper and lower range of valve guide, since experience has shown that the wear at these points is higher.<\/div>\n
Check valve guides with inspection mandrel and cylinder head disassembled.<\/div>\n
Valve guides, which are worn outside on seat of valve stem seal, should be replaced, since the valve stem seal is no longer tightly seated.<\/div>\n<\/div>\n<\/td>\n

Valve guides which are loosely seated in cylinder head must be inserted in newly made basic bores.   Checking valve guide Upon removal of valve spring and valve stem seal, the wear on valve guide can be determined in installed condition by moving valve stem predominantly cross\u00adwise in relation to engine. As a reference value, a max. wear of approx. 1.2 for 1000 km (0.12 mm for 100 000 km) should be assumed.   05.2-285\/2 F3       However, this value does not apply to upper and lower range of valve guide, since experience has shown that the wear at these points is higher. Check valve guides with inspection mandrel and cylinder head disassembled. Valve guides, which are worn outside on seat of valve stem seal, should be replaced, since the valve stem seal is no longer tightly seated.   Assigning and inserting valve guides 1\u00a0 \u00a0 Knock-out valve guide with knock-out mandrel from direction of combustion chamber or press out. 2\u00a0 \u00a0 Visually check basic bore in cylinder head for score marks and deposits. Equalize deposits (if any) by means of a small file.   Attention! A basic bore with punched-in code number, e.g. 2 (arrow) should be associated with the respective valve guide with regard to the applied color code or the measured OD.   On exchange engines the basic bore in cylinder head is larger than normal. This means, that the punched-in code numbers in cylinder head are no longer in accordance with basic bores according to table. In such a case, measure basic bore or OD of knocked-out valve guide prior to pertinent association.   05.2-285\/3 F3       Association of a valve guide with a not-refinished basic bore in cylinder head   Punched-in code\u00a0 \u00a0 \u00a0 \u00a0 Color code number adjacent\u00a0 \u00a0 \u00a0 \u00a0of valve to basic bore in\u00a0 \u00a0 \u00a0 \u00a0 \u00a0guide2) cylinder head1) Overlap in cylinder head Machining note   without 0.015-0.028 Knock-in valve guide with knock-in mandrel.   0 brown 0.020-0.027 Undercool valve guide, knock-in with knock-in mandrel or heat cylinder head, knock-in with knock-in mandrel.   gray-green 3)\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 0.028-0.040 Undercool valve guide, knock-in with knock-in mandrel, ream ID or heat cylinder head, knock-in, ream ID with reamer.   brown 0.019-0.026 Knock-in valve guide with knock-in mandrel.   1 gray-green 0.022-0.033 Undercool valve guide, knock-in with knock-in mandrel or heat cylinder head, knock-in with knock-in mandrel.   gray3) 0.027-0.039 Undercool valve guide, knock-in with knock-in mandrel, ream ID or heat cylinder head, knock-in, ream ID with reamer.   gray-green 0.016-0.027 Knock-in valve guide with knock-in mandrel.   2 gray 0.021-0.033 Undercool valve guide, knock-in with knock-in mandrel or heat cylinder head, knock-in with knock-in mandrel.   gray-brown3)4) 0.027-0.038 Undercool valve guide, knock-in with knock-in mandrel, ream ID or heat cylinder head, knock-in, ream with reamer.   M After knocking-out valve guide, the basic bore is not essentially larger than the series basic bore.
