3.3 - Trouble Shooting, continued

Problem

Cause

Solution

Carriage does not move when power is applied.

Engine is under strain.

Carriage Shifting Mechanism cam arm follower is

not in “pave” position.

Check cam arm follower tension and verify that

cam arm movement is not obstructed.

Carriage decelerates, stops and then will not

accelerate.

Carriage Shifting Mechanism cam arm follower is

not adjusted properly.

Adjust upper rail or adjust cam arm.

See Maintenance - Shifting Mechanism.

Carriage Shifting Mechanism reversing valve

spool does not shift.

Check for cause and correct.

See Maintenance - Shifting Mechanism.

If valve mount bolts have recently been tight-

ened, the reversing valve body may be distorted

causing the spool to “bind”.

Loosen valve body mount bolts and tighten bolts

evenly a little at a time.

Automatic machine travel is more when carriage

is near drive end.

Upper rail on shifting mechanism requires adjust-

ment.

Adjust upper rail down.

See Maintenance - Shifting Mechanism.

Carriage travel does not slow down enough

before automatic reversing. The result is exces

sive jerking.

Cam arm requires adjustment.

Adjust cam arm.

See Maintenance - Shifting Mechanism.

Automatic machine advance is not functioning.

Manual bogie advance is functioning.

Check valve is stuck.

Lightly tap check valve. Replace valve if malfunc-

tion recurs. Valve is located beneath Power Unit.

See Parts Book

Speed and power loss for carriage travel drive

motor when carriage return direction is normal.

Clevis end or rear spool stop is unscrewing from

reversing valve spool.

Clean oil from clevis end threads. Assemble and

loctite.

Carriage travel reversing valve is worn or faulty.

Replace valve.

Hydraulic motor worn or damaged.

Replace motor.

Paving roller stops under load while augers oper-

ate normally.

On reversing valve, relief valve pressure setting

is too low or foreign material is unseating relief

valve

Adjust relief pressure setting * or disassemble

relief valve and remove material or replace with a

valve with correct relief setting. * 1200 PSI relief

valve pressure should be verified for replacement

valves before installation.

Paving roller does not operate or stops under

load. Relief valve is okay. Augers operate nor-

mally.

Roller motor is damaged or worn. Reversing

valve may have developed internal damage.

Replace motor.

Replace reversing valve.

Paving roller slows or stops under load.

Excessive bearing noise when roller spins or

bearing excessively hot.

Paving roller shaft bearings damaged.

Replace bearings.

Paving roller operates when carriage travels

in one direction but does not operate properly

and/or reverse when carriage travel direction is

reversed.

Hydraulic hose quick disconnect is malfunction-

ing.

Replace quick disconnect.
