Valve Spring



Intake and exhaust valve springs are of the same length. The installed spring length is changed or adjusted through the addition or removal of spacers located under the springs.


The valve springs must always rest on the steel washer and never on the spacers since the spring could damage the spacers.

  1. Install- special tool P 10 with the respective spring retainer and both valve keepers.
  2. Determine the indicated value and correct it, if necessary. by adding or removing spacers.
  3. Install valve springs so that the closely wound coils rest on the 1,5 mm thick washer (see note, above).


Valve springs made by various manufacturers are supplied under the same spare part number. However, all springs (progressive or linear coils) may be paired in one engine.

a = Installed length
b = Steel washer
c = Spacers

Installed length of valve springs is:
Intake = 41,0 mm (1.61in)
Exhaust = 40,5 mm (1.59in)
