What This ASV RT-135 Service Manual Gives You

Every procedure in this manual is written against the specific RT-135 Max Series machine, not a generic track loader. Torque values, pressure settings, and cycle times are all given for this model: transmission mounting bolts at 85 ft-lb with blue Loctite, drive sprocket lug bolts at 202 ft-lb dry, 10-inch idler wheel retaining bolt at 180 ft-lb with red Loctite, and 15-inch idler retaining nut at 350 ft-lb dry. Hydraulic pressures are stated explicitly throughout the pressure test chapter, including the 5801 psi (400 bar) drive relief, 3300 psi low-flow auxiliary relief, 4060 psi high-flow auxiliary relief, and 392 +/- 30 psi charge pressure.

The circuit diagram chapter alone is worth the price of the manual – charge circuit, auxiliary circuit, control circuit, and drive circuit are laid out with color keys (charge pressure, high pressure, return, inlet) so you can trace oil flow from the charge pump through the fan control block, oil cooler, check valves, and filter back to the tank. The lift arm control valve diagram shows every relief valve setting on the block face, so you know which relief to adjust when a function is weak.

For engine work, the RT-135 runs the Cummins QSF3.8 – 3.8 liter, 132 hp, 360 lb-ft of torque. The manual covers the complete engine removal sequence, including the driveshaft coupler, exhaust/SCR removal, DEF tank, air cleaner, accessory belt, A/C compressor set-aside, fuel line quick disconnects, starter and alternator cable removal, engine ECU harness, and the four engine mount bolts. Every step is illustrated with in-chassis photos so you can see exactly where the fastener is before you start.

The undercarriage chapter is especially detailed for anyone doing track work. Track tension is checked with a 90 lb down-force at midpoint between drive sprocket and front idler – deflection should read between 3/4″ and 1″. Adjustment is done at the turnbuckle. Sprocket rollers are inspected every 50 hours and replaced at 35% of original thickness (.088″). The bogie wheel service procedure walks through metal face seal disassembly, hub cleaning, bearing inspection, face seal reassembly with isopropyl alcohol wipe-down and 10W-30 oil film, and final torque of the wheel retaining bolts to 180 ft-lb (244 Nm).

Which Jobs This Manual Supports

The RT-135 Max Series Service Manual 0405-203 covers jobs across the whole machine, including:

• Routine maintenance – oil and filter changes, hydraulic fluid and filter service, air cleaner service, water separator draining, coolant change, radiator/oil cooler cleaning, grease points
• Undercarriage repair – track removal and installation, track tension adjustment, idler wheel replacement, bogie wheel and hub rebuild, front and rear axle removal
• Hydraulic service – charge pressure adjustment, auxiliary pressure and flow checks, lift arm pressure troubleshooting, drive pressure testing, cylinder reseal, lift arm control valve disassembly, drive pump relief and solenoid service, auxiliary pump disassembly
• Engine service – battery, exhaust, air cleaner, DEF tank, full engine removal and installation
• Electrical – fuse panel identification, control system fault codes, service tool connection, display programming and software update
• Diagnostics – troubleshooting flow charts for every control system fault code (propel, boom, bucket, high flow, low flow, quick attach, fan control)

Every one of these procedures tells you the tool you need, the bolts to remove, the values to hit on reassembly, and the steps to verify the fix. That is what separates a proper service manual from a parts diagram or an owner’s booklet.

Why the Correct Procedures and Specs Matter on the RT-135

The RT-135 is a high-flow, high-pressure compact track loader – drive pressure runs at 5801 psi (400 bar) and high-flow auxiliary at 4060 psi. Guessing at torque values or relief settings on a machine like this is expensive. A relief valve set too low and the machine stalls under load. Set too high and you blow seals or crack a pump housing. The manual gives you the exact figure and the exact adjustment method, whether that is adding or removing shims on the charge relief, turning an allen screw on the high-flow relief, or swapping a suspect relief to confirm the fault.

The troubleshooting chapter works by symptom – machine will not crank, cranks but will not start, starts but no hydraulics, tracks move but lift arms don’t, high hydraulic oil temperature, engine overheat. Each symptom has a list of possible causes and a link to the control system troubleshooting guide if the cause is electrical. The control system tables go fault code by fault code: display message, what it disables on the machine, what causes it, and the fix. That level of detail is what turns a two-day diagnosis into an hour-long repair.
