14. Lubricating oil flow into theshuttlehasbeenreducedwith
a restriction (diam. 5 mm, K41105 ---). This modification bal-
ances lubr. oil flow into the F --- and R--- clutches. In connection
with this modification the DPS and shuttle lubr. oil flow has
been improved.
15. A non---return valve From ser. no. K50440 inc l . has been
fitted to prevent oil pressure escape from pressure accumu-
lato r into the hydraulic pump and the brake valve.
This ensures that the parking brake is not engaged too fast af-
ter engine stop. Note! This happens only in case that the engi-
ne stops itself (e.g. fuel runs out) when the driving speed is
over 5 km/h. Does not affect the normal function of the par-
king brake.
