LASH ADJUSTER LEAK DOWN TEST
Caution
DThe lash adjuster is a precision part. Keep it free from dust and other foreign matters.
DDo not disassemble lash adjuster.
When cleaning lash adjuster, use clean diesel fuel only.
(1)Immerse the lash adjuster in clean diesel fuel.
(2)While lightly pushing down inner steel ball using the Special Tool (Air bleed wire MD998442), move the plunger up and down four or five times to bleed air.
Use of the Special Tool (Retainer MD998441) helps facilitate the air bleeding of the rocker arm mounted type lash adjuster.
(3)Remove the Special Tool (Air bleed wire MD998442) and press the plunger. If the plunger is hard to be pushed in, the lash adjuster is normal. If the plunger can be pushed in all the way readily, bleed the lash adjuster again and test again if the plunger is still loose, replace the lash adjuster.
Caution
D Upon completion of air bleeding, hold lash adjuster upright to prevent inside diesel fuel from spilling.
(4)After air bleeding, set lash adjuster on the Special Tool (Leak down tester MD998440).
(5)After plunger has gone down between 0.20 to 0.50 mm, measure time taken for it to go down a further 1 mm. Replace if measured time is out of specification.
