Measuring Valve Spring Compression
IMPORTANT: Replacement valve springs (R133891)
have higher working loads than older
springs (R116585). Newer valve springs
(R133891) have two green paint stripes
for identification. Valve springs must be
replaced in sets of two with new
rotators. DO NOT intermix springs
across valve bridges.
1. Inspect valve springs for alignment, wear, and damage.
2. Using D01168AA Spring Compression Tester, check
valve spring tension. Compressed height must be
within specification given below.
