24H - Valtra 6000 Workshop Manual

37. Autocontrol 5
E. Manual setting of indexes for DPS and shuttle in AC 5 and 5.2
NOTE! When needed, manual setting can be done in the AC5.2, if automatic calibrating cannot give a correct value.
1. Drive the tractor warm, transmission temperature +30˚C...+65˚C.
2. Shuttle in P ---position, gear H1, with accelerator lever 1200 ---1500 r/min.
Note! It is unnecessary to stop the engine after the index setting. Enough is that the tractor current is switched off and then immedi-
ately on, so that the tractor can be driven. In the same way not to stop the engine it can be moved to the setting mode FIII. In this
case must simultanious be pressed switches, which activate the test mode.
3. Shuttle pre ---filling time indexes
Set the F ---clutch initial pressure index to: ---6
Setting mode FIII g Set the R ---clutch initial pressure index to: ---6
H1 H1
Set the F ---clutch pre ---filling time index to: ---3
1200 ---1500 r/min
Set the R ---clutch pre ---filling time index to: ---3
Make starting drivings forwards with the shuttle lever. Increase pre ---fil-
ling index one step by turns (---3, ---2, ---1, 0, +1, +2, +3, +4...) until
the jerk is disturbing. Diminish the index 1 ---2 steps. Check that in the
starting driving there is a clear but small jerk.
Set the R ---clutch pre ---filling index in the same way
4. Shuttle initial pressure indexes
Increase F ---direction initial pressure index one step by turns (---4, ---3,
Setting mode FIII ---2, ---1, 0, +1, +2, +3, +4...) and make starting drivings with the shut-
H1 tle lever. Index is suitable, when the tractor accelerates evenly and there
1200 ---1500 r/min is not delay or break in the traction.
Set the R ---direction initial pressure index in the same way Set the R ---direction initial pressure index in the same way S t th R di
Test mode FII Start the engine and activate the test mode FII and find point A4.
H1 Depress the clutch pedal and switch on the forward driving (F). Raise
1200 ---1500 1/min the pedal slowly and watch the display and observe in which pedal
position the tractor starts to move (% ---value).
Switch on the R ---direction. When starting driving rearwards the % ---va-
lue must be about 10 % ---units greater that when starting driving for-
wards. E.g. in forward driving 20/rearward driving 30. If the forward
driving value is the same or greater that the rearward driving value, re-
check the initial pressure indexes. NOTE! In the AC 5.2 can the pedal
engaging point be adjusted with a separate index (see page 371/10).

ti i iti l
Check the function of the DPS in different situations: different driving speeds, in traction, witho-
ut traction, in engine braking.
--- If the traction breaks when engaging the speed, increase the index.
--- If the engagement is too sharp, decrease the index
switching the
quick ---shift gear (during shifting).
