Ten chapters over 240 pages make this Vibromax 1105 service manual PDF (publication SM95005) a single factory reference for four single drum roller models in the 1105 family, from engine removal through drum exciter bearings. Starter and charging circuits are drawn separately for the Cummins 6B5.9C and 6BT5.9C engines, and wire charts list the leads of each harness, covering the vibration, high speed, lighting and cab circuits. On the hydraulic side, a full machine schematic maps suction, drain, charge and propulsion lines, while diagnostics cover internal leakage, pump servo control and the vibratory system. Set your test gauges for 20 bar (285 PSI) charge and 140 bar (2000 PSI) steering. Ordering a replacement wire harness 7241/80315 (0)? Its matching wire chart lets you confirm each circuit first. Bookmarks take you straight to the chapter you want, and the text layer finds any harness number in seconds, so download your copy and keep it with the roller.

Vibromax 1105, 1106, 1405, 1805 Common Problems This Manual Covers
Vibromax 1105, 1106, 1405, 1805 roller starter solenoid clicks but engine will not crank
Fasten the manual shut off lever on the injection pump in the OFF position before testing, per the caution on page 69. A clicking solenoid points to a poorly charged battery, corroded cables, a bad connection, poor ground or a bad solenoid. Measure starter case to negative battery terminal while cranking (page 70); over 0.5 volts means poor ground. Check the starter motor supply terminal for 8.5 to 10.0 volts on page 71.
Manual Section: Starter System Diagnostics p. 70Charging system alternator warning lamp stays on with key on and engine running
Check the lamp chart on page 66. Lamp on with key on and engine running indicates a regulator problem. With the engine off, verify 12 volts between the B+ terminal and a good engine ground (page 67). Then run at half throttle with lights on; V1 must not exceed 0.5 volts and V2 must not exceed 0.25 volts, or you have resistance in cables or connectors.
Manual Section: Charging System Diagnostics p. 66Hydrostatic drive moves weakly or loses drive under load at full engine RPM
Test charge pressure at port #1 on the test station on the right side, expecting about 290 PSI per page 126. Run maximum engine RPM at normal operating temperature and compare no load and maximum load readings. More than 10% difference means excessive internal leakage; cap the motor pressure lines to isolate the pump or charge relief valve.
Manual Section: Propulsion System Diagnostics p. 126Roller creeps forward or backward with the operator control lever in neutral
Check the adjustment of the control cable running from the operator's platform to the pump servo control first, following page 127. If the cable is adjusted properly, move on to the parking brake: inspect for mechanical hang-up and worn brake discs, and test the pressure switch as covered under Parking Brake Diagnostics on page 140.
Manual Section: Propulsion System Diagnostics p. 127Machine will not move in forward or reverse when the control lever is moved
Check the solenoid valve at the top rear of the pump assembly for a fault, possibly electrical, following page 127. As a quick test, verify brake release pressure, which the same solenoid valve controls, reads 290 PSI. If release pressure is missing, chase the solenoid valve and its wiring first.
Manual Section: Propulsion System Diagnostics p. 127Vibratory system output weak, with vibration frequency or pressure reading low during operation
Measure vibration frequency and test vibratory pressure following the diagnostics on page 134. Check start up pressure against 420 bar (6090 PSI) and operating pressure against 100 to 150 bar (1400 to 2200 PSI). Record both readings and compare them to these values before replacing any vibration components.
Manual Section: Vibratory System Diagnostics p. 134Frequently Asked Questions
Why is a Vibromax 1405 not vibrating or moving?
If the machine does not move or moves slowly, check if the charge pressure is at its normal level of 290 PSI. If the pressure is low, leakage in the servo control cylinder may be excessive, or there may be a problem with the solenoid valve. For vibration issues, ensure the engine is at maximum RPM and test hydraulic pressures at taps #3 and #4 of the hydraulic test station. p. 126
What are the replacement specifications for the engine fuel filters on the Vibromax 1105, 1106, 1405, 1805?
The engine uses dual replaceable elements and a spin-on cartridge for the fuel filter system. The fuel capacity for all models is 105 gallons (397 liters). p. 17
What is the correct engine oil viscosity for a Vibromax roller at 20 degrees Fahrenheit?
According to the Engine Oil Viscosity Chart, at 20 degrees Fahrenheit (-7 degrees Centigrade), you should use 10w40, 15w30, or 10w30 viscosity engine oil. Always use oil with an API service classification of CD. p. 27
What is the torque specification for the wheel lug nuts on a Vibromax 1105/1106/1405/1805?
The wheel lug nuts must be tightened and torqued to 288 ft lbs (390 Nm). It is critical to re-tighten these nuts every 8 hours until the torque stabilizes. p. 156
What is the procedure for bleeding the hydraulic brake system on a machine with a drum drive motor brake?
On machines equipped with a brake in the drum drive motor, it may be necessary to bleed the brake system at the motor brake port after installation or maintenance. Ensure all motor ports are filled with clean hydraulic oil prior to hose installation. p. 179
Is this Vibromax 1105 manual a PDF I download?
A single searchable PDF file of 240 pages, downloadable right after payment. Nothing ships, nothing waits in the mail.
Is printing allowed for this Vibromax 1105 Service Manual?
Yes. Many buyers print one chapter at a time for their own shop and keep the rest on a tablet.
