Fault Phenomenon: Bomag BF800C paver transmission cannot engage a specific gear.
Troubleshooting Process:
– Checked solenoid valve: coil resistance for that specific gear is infinite.
– Checked wiring: line supply normal.
– Checked spool: spool stuck.
– Checked fuse: fuse intact.
Root Cause: The transmission shift solenoid valve coil burnt due to overheating or insulation aging, preventing the spool from actuating.
Required Parts: Replace transmission shift solenoid valve coil.
