SANY Hydraulic Oil Specs & Filter Replacement Guide

Before ordering replacement elements from our SANY filters category hub or selecting hydraulic fluid for a scheduled service, verify the oil grade table, tank capacity, and filter part numbers against the machine's operation and maintenance manual and serial plate.

• In our SANY filters category hub, SANY filters covers engine, hydraulic, fuel, and air filters, plus kits when we can confirm the model and serial range, and a filter kit without a model is not a quote because the pack contents change.

• In our filter, controller, and seal kit identification guide, similar housings or dimensions can conceal a different service specification, so a service kit containing several filters should list the individual references and quantities, and operators should photograph the label, both ends, seal seat, threads, and any attached fittings or sensors.

Use our SANY excavator nameplate guide to record the machine model and serial number, check known part numbers in the part-number lookup tool, or browse more maintenance and identification articles in news and guides.

SANY hydraulic oil specifications by ambient temperature and fluid classification

Review the international hydraulic fluid classification and viscosity rules below when comparing mineral anti-wear hydraulic oil grades for a SANY excavator.

• ISO 11158:2023 (valid from 13.10.2023; standard history lists prior edition ISO 11158:2009) specifies the minimum requirements for new mineral oil hydraulic fluids in categories HH, HL, HM, HV, and HG, and is intended to be used in conjunction with ISO 6743-4.

• ISO 6743-4:2015 (valid from 20.07.2015) establishes the detailed classification of fluids of Family H (Hydraulic systems) which belong to class L, is intended to be read in conjunction with ISO 6743-99, and does not include automotive brake fluids or aircraft hydraulic fluids.

• ISO 3448:1992 (valid from 09.09.1992) establishes a system of viscosity classification for industrial liquid lubricants and related fluids including mineral oils used as hydraulic fluids, with the usual method for kinematic-viscosity determination specified in ISO 3104.

• Under the ISO 11158 hydraulic oil classification, both HM and HV are anti-wear hydraulic oils whose key difference is viscosity index: HM oils have a standard viscosity index for narrow to moderate temperature ranges, while HV hydraulic oils contain viscosity index improvers to remain fluid during cold start and operate across wider temperature ranges.

Documented per-model SANY hydraulic oil grade tables

Compare the hydraulic oil grade and ambient temperature tables published in specific SANY operation manuals before selecting a drum for refill or top-up:

• For the SANY SY26U crawler hydraulic excavator, Operation Manual-11-2019 specifies L-HM46 A wear-resistant hydraulic oil for ambient temperatures of -10 – 50 °C.

• For the SANY SY26U excavator, Operation Manual-11-2019 specifies L-HM68 wear-resistant hydraulic oil for ambient temperatures of 10 – 50 °C.

• For the SANY SY26U excavator, Operation Manual-11-2019 specifies L-HV32 low-temp, wear-resistant hydraulic oil for ambient temperatures of -30 – 10 °C.

• For the SANY SY26U excavator, Operation Manual-11-2019 also lists hydraulic oil SAE 30 for ambient temperatures of -20 – 40 °C.

• In the SANY SY215C LC/SY225C LC Operation and Maintenance Manual, the hydraulic oil temperature guidance instructs operators to use ISO VG 46 anti-wear hydraulic oil in general temperate climates.

• In the SANY SY215C LC/SY225C LC Operation and Maintenance Manual, the hydraulic oil temperature guidance instructs operators to use ISO VG 32 low-temperature anti-wear hydraulic oil (pour point is -43.6°F [-42°C]) in generally arctic areas where ambient temperatures can reach -22°F (-30°C) during operation.

Hydraulic fluid integrity and contamination rules

Follow the fluid handling rules documented in the SANY operation manual when topping up or changing hydraulic oil:

• The SANY SY215C LC/SY225C LC Operation and Maintenance Manual states never to mix lubricants of different types or viscosities (weights), and never to overfill the system that is being serviced.

• On the SANY SY215C LC/SY225C LC, the hydraulic system maintenance guidelines state not to use any additives in the hydraulic oil and to replace hydraulic oil that has been subjected to overheating or damaged components.

• On the SANY SY215C LC/SY225C LC, the hydraulic system maintenance guidelines instruct operators to change the hydraulic oil filter as recommended and to cap and plug all openings after removing components for service or repair.

Comparing published SANY hydraulic tank capacities across excavator series

Verify the hydraulic tank volume in the manual matching the machine's model suffix and engine configuration before ordering bulk hydraulic oil:

• In the SANY SY26U Operation Manual-11-2019, the hydraulic tank fluid capacity is 30 l.

• When checking the hydraulic oil level indicator in Section 5.6.4 of the SANY SY26U Operation Manual-11-2019, the fill level must be positioned between the MIN and MAX marks.

• In the SANY Europe SY35U specification brochure, the hydraulic oil tank service refill capacity is 40 L, and the load-sensing hydraulic system uses variable-capacity piston pumps with 88 L/min maximum flow and a 27 MPa implement circuit relief setting.

• In the SANY SY155U Quick Start Guide, the hydraulic oil tank service refill capacity is 140 l, and at the first 500hrs service all oils and filters are changed except hydraulic oil.

• SANY's official SY135C (Tier 4F & Stage V) small excavator specification lists an Isuzu 4JJ1X engine with 78.5 kW engine power, 14.87 t operating weight, and a 175 L hydraulic tank.

• SANY's official SY215C medium excavator specification lists a 4M50 engine with 118 kW engine power, 21.9 t operating weight, a 340 L fuel tank, and a 239 L hydraulic tank.

• By contrast, SANY's official SY215C LC medium excavator specification lists a CUMMINS QSB6.7 engine with 129 kW engine power, 23.55 t operating weight, a 370 L fuel tank, and a 200 L hydraulic tank.

• In the SANY SY215C LC/SY225C LC Operation and Maintenance Manual technical specifications table, the hydraulic tank capacity is listed as 60.5 gal. (230.0 L).

• SANY's official SY365C (T4f) large excavator specification lists 36.7 t operating weight, 1.5 m³ bucket capacity, a 540 L fuel tank, and a 340 L hydraulic tank.

Synchronized hydraulic return, suction, pilot, and breather filter intervals

Coordinate return filter, pilot filter, suction strainer, and tank breather service with hydraulic oil sampling and drain intervals.

• ISO 16889:2022 (valid from 25.01.2022) describes a multi-pass filtration performance test with continuous contaminant injection for hydraulic fluid power filter elements that exhibit an average filtration ratio greater than or equal to 75 for particle sizes ≥ 25 µm(c) and a final reservoir gravimetric level of less than 200 mg/L, across three test conditions with base upstream gravimetric levels of 3 mg/L, 10 mg/L, and 15 mg/L.

• ISO 4406:2021 (valid from 07.01.2021; standard history lists prior edition ISO 4406:2017) specifies the code to be used in defining the quantity of solid particles in the fluid used in a given hydraulic fluid power system.

Scheduled hydraulic maintenance intervals by manual

Compare the break-in and recurring hydraulic filtration schedules across published SANY manuals:

• On the SANY SY215C LC/SY225C LC maintenance schedule, the Daily or 10 Hours checks include checking the hydraulic pump mounting fasteners, checking the hydraulic tank oil level, and checking the hydraulic line connections.

• On the SANY SY215C LC/SY225C LC maintenance schedule, checking the hydraulic hoses and lines is required under the Weekly or 50 Hours interval.

• On the SANY SY215C LC/SY225C LC maintenance schedule, the Monthly or 250 Hours tasks require initial replacement of the hydraulic pilot oil filter element and initial replacement of the hydraulic oil tank return filter.

• On the SANY SY215C LC/SY225C LC maintenance schedule, the 500 Hours tasks require collecting a hydraulic oil sample, checking the hydraulic oil pump, checking the hydraulic hoses and lines, and replacing the hydraulic system breather filter.

• In the SANY SY155U Quick Start Guide service intervals chart, the Hydraulic Oil Suction Filter is scheduled for inspect and clean (I C) Every 1000hrs and replacement (R) Every 4000hrs alongside Hydraulic Oil replacement, while hydraulic oil must be changed at 2000hrs if used with attachments.

Hydraulic breaker duty interval reductions

Shorten hydraulic oil and filter replacement intervals when the excavator operates with a hydraulic breaker attachment:

• Under the Hydraulic Breaker Maintenance Interval in the SANY SY215C LC/SY225C LC manual, hydraulic oil breaks down faster on machines equipped with a hydraulic breaker than on machines equipped with a bucket, and the manual instructs operators to change the hydraulic oil and filters every 400 hours on breaker-equipped machines.

• In the SANY SY215C LC/SY225C LC manual, the Hydraulic Breaker Maintenance Interval notice states that the hydraulic oil filter must be replaced after 250 hours with a breaker operating rate above 50%.

• In the Change the Hydraulic Oil section of the SANY SY215C LC/SY225C LC manual, a notice states that if a breaker attachment is used, change hydraulic oil and filters every 500 hours to avoid damage to the machine.

Workshop procedure for tank depressurization, filter housing cleaning, and torque checks

Follow the complete circuit depressurization, tank venting, housing inspection, and seal replacement sequence when servicing the hydraulic reservoir and filter assemblies.

• In the Change the Hydraulic Oil procedure for the SANY SY215C LC/SY225C LC, after parking on a flat, level surface and positioning the work equipment as shown on the hydraulic tank decal, the operator must start and idle the engine for 1 minute, shut down the engine, turn the key switch to ON, place the hydraulic lockout lever in the open (unlocked) position, and cycle the joysticks controls and travel control levers and pedals to relieve pressure in the hydraulic circuits.

• On the SANY SY215C LC/SY225C LC, after turning the key switch to OFF, locking the hydraulic lockout lever, and cleaning the top of the hydraulic tank, the operator removes the wing nut from the breather valve and presses the hydraulic tank vent button to relieve pressure in the hydraulic tank.

• During the hydraulic oil change on the SANY SY215C LC/SY225C LC, after draining the tank and replacing the O-ring on the drain plug, the operator removes the hydraulic return filter cover, removes the spring and withdraws the filter, checks the bottom of the return filter housing and removes any debris, inserts a new filter in the return filter housing, and replaces the O-ring.

• During the same SANY SY215C LC/SY225C LC procedure, the operator removes the hydraulic suction strainer cover, uses a pull rod to remove the strainer, cleans the strainer of all debris (replacing the strainer if damaged), replaces the O-ring, installs the strainer, and replaces the hydraulic system breather filter.

• To complete the SANY SY215C LC/SY225C LC oil change, the operator adds hydraulic oil to the tank through the suction strainer opening until the hydraulic oil level displays full in the sight glass on the hydraulic tank, installs the suction strainer cover, starts the engine and runs the engine for 10 minutes to circulate the oil in the hydraulic system, and then checks the oil level in the tank and checks for leaks.

• When replacing the hydraulic pilot filter element on the SANY SY215C LC/SY225C LC, after relieving circuit and tank pressure, the operator opens the right rear door and locates the hydraulic pilot filter housing behind the hydraulic oil filter, places a container under the pilot filter housing to catch leaking oil, removes the pilot filter housing and filter element, cleans the inside of the filter housing with clean fuel, and installs a new gasket, O-ring, and pilot filter element.

Published tightening torques on the SANY SY26U

Check the screw connection torque table in the matching machine manual before tightening hydraulic filter housings and drain plugs:

• In the SANY SY26U Operation Manual-11-2019, the tightening torque for the hydraulic oil suction filter is 135 ±20 Nm.

• In the SANY SY26U Operation Manual-11-2019, the tightening torque for the hydraulic oil return filter is 60-80 Nm.

• In the SANY SY26U Operation Manual-11-2019, the tightening torque for the hydraulic oil drain plug is 162 ±14 Nm.
