Caterpillar SR118
Maintenance schedule, common problems & OEM parts breakdown
The Cat SR118 is a two-stage, hydraulically driven snow blower work tool designed to mount on compact track loaders, skid steer loaders, and compact wheel loaders. It carries no onboard engine, fuel system, or coolant circuit; all power comes from the carrier's auxiliary hydraulic circuit, which drives an internal chain-and-gear train turning a reversible auger and impeller. Operating weight sits around 433 kg (954 lb), placing it in the mid-size class of Cat's compact snow blower lineup that spans the SR115, SR117, SR118, SR121, SR318, and SR321. The SR-1xx series in that lineup is sized for skid steer, compact track loader, and compact wheel loader carriers, while the SR3xx series steps up to larger flow and wider intake for bigger wheel loaders.
Within that family, the SR118 is distinguished by its hydraulic sizing and carrier fit: it is built to run on Cat's 226D3-299D3 skid steer/CTL range and the 906-908 compact wheel loaders, sitting between the narrower SR115/SR117 and the larger SR121 in intake capacity. In the used and parts market, that flow-and-pressure window matters more than raw dimensions. A buyer has to match the SR118's roughly 76-87 L/min flow and 200-230 bar pressure requirement to the host carrier's auxiliary circuit, or the auger/impeller runs underpowered in heavy snow or gets over-stressed at the drive train. Because Cat documents the SR115, SR117, SR118, SR121, SR318, and SR321 in a shared operation and parts manual set, buyers sourcing wear parts such as cutting edges, chain, or bearings need to confirm SR118-specific fitment rather than assume interchange across the whole family.

SR118 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Auger and impeller bearings (grease fittings, 3 points: auger bearing, left impeller bearing, right impeller bearing) | No listed fill capacity - grease fitting is purged by hand-pumping until fresh grease appears; not a sealed reservoir | Cat Multipurpose Grease (MPGM) containing 3-5% molybdenum disulphide, meeting MIL-M-7866; apply every 30 service hours |
| Discharge chute chain and coupler chain | No listed fill capacity - oil is brushed/applied directly to chain links after guard removal, not held in a case | Clean engine oil (Cat DEO-class or equivalent), applied every 30 service hours |
| Hydraulic drive circuit (auger/impeller motor) | No onboard reservoir - the SR118 has no hydraulic tank of its own; it draws oil from and returns oil to the host carrier's auxiliary hydraulic system | Per the OMM: use only the oil specified for the host machine's hydraulic system, per that machine's own Operation and Maintenance Manual |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the SR118 beyond the schedule
Predictive Maintenance & Fluid Analysis
The SR118 has no internal oil sump, so predictive care centers on the carrier's hydraulic fluid and the attachment's grease points. Sample the carrier's hydraulic oil on its own interval; contaminated or degraded fluid feeding the SR118's drive motor wears the chain and bearings without obvious symptoms. Track grease consumption at the auger and impeller bearings between 50-hour services; a sudden drop signals a failed seal. Watch chute rotation response through its 270-degree travel: sluggish or hesitant movement warns of internal motor wear or hydraulic contamination before it becomes a hard failure.
Corrective & Common Repairs
Most SR118 field repairs trace to three points: sheared auger drive pins from ingested debris or frozen snow packs, a stretched or thrown drive chain from missed lubrication, and worn or cracked bolt-on cutting edges from curb strikes. Reversible auger and impeller flighting extends service life before parts need replacing. Hydraulic hose chafing at the chute rotation cylinder and quick-coupler fittings is the next most common failure, especially on carriers that mount and dismount the attachment daily. Replace sheared drive hardware only with matched-grade pins; harder substitutes push shock load into the gearbox.
Overhaul & Rebuild Points
A full SR118 rebuild centers on the auger/impeller shaft and bearing bores, the chain-and-sprocket drive train, and the chute rotation motor. Check shaft straightness and bore condition before repacking bearings; an out-of-round bore lets grease escape and invites ice intrusion. Replace chain and sprockets as a matched set rather than mixing worn and new components, which accelerates re-wear. Inspect the quick-coupler mounting plate pins and bushings for play, since a loose mount transmits vibration into the drivetrain. Repair housing welds around mounting brackets before returning the unit to service.
Seasonal & Environment Servicing
Before first snowfall, grease every auger, impeller, and chain point, confirm hydraulic flow and pressure match the carrier's rating, and cycle the chute through full rotation to work grease into the pivot. Road salt and slush accelerate corrosion on the housing, chain, and mounting hardware; rinse and dry the unit after each shift and coat exposed metal to slow rust. At season's end, clear residual snowmelt from the housing, grease all points before storage, and store the attachment off the ground to keep moisture out of the mounting plate and chain guard.
SR118 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| None (no onboard ECM) | The SR118 is a passive, hydraulically driven attachment (auger plus impeller, with hydraulic chute rotate/tilt actuators). It has no engine, controller, or diagnostic module, so it cannot generate or display a fault code of its own. | Not applicable — this is a design characteristic, not a malfunction. | Treat any code that appears while the SR118 is mounted and running as a host-carrier code, not a tool-specific code. |
| 41-4 (CID 0041, FMI 04) | Carrier-side code for 8-volt DC sensor supply voltage below normal. This shared reference circuit also feeds the auxiliary hydraulic thumbroller/control circuit that runs the SR118's auger and chute functions. | A short to ground on a sensor or switch signal wire that shares the carrier's 8V reference circuit, sometimes traced to attachment-side wiring or connector damage. | Isolate by disconnecting the attachment's electrical connection and any aux sensors one at a time; inspect the carrier harness and connectors before suspecting the controller. |
| 1228 (CID, Attachment Lockout Switch) | Carrier code for the attachment lockout/coupler-lock switch circuit that confirms a work tool such as the SR118 is securely pinned to the quick coupler before auxiliary hydraulic flow is enabled. | Attachment not fully latched, a misadjusted or failed lockout switch, or damaged wiring at the coupler. | Confirm the SR118 is fully pinned and latched to the coupler, then inspect the lockout switch and its connector on the carrier per the carrier service manual. |
| Auxiliary hydraulic solenoid circuit fault (open or short — carrier FMI 3/5/6 pattern) | General carrier diagnostic pattern for the auxiliary control valve solenoids that drive the SR118's chute rotate and chute tilt functions through the 14-pin attachment connector. | Corroded or bent pins in the 14-pin connector, chafed harness near the attachment coupler, or a failed solenoid coil in the carrier's auxiliary valve stack. | Inspect the 14-pin electrical connector and harness for damage, test solenoid coil resistance, and repair wiring before replacing the valve. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
SR118 attachments & work tools
Host carrier size class / coupler system
The SR118 mounts to skid steer loaders, compact track loaders, and compact wheel loaders via Cat's standard skid steer quick-attach coupler. The coupler is height-adjustable across three positions so the same unit can be matched to different carrier configurations.
Hydraulic flow/pressure requirement
Rated for standard-flow hydraulic circuits. Cat's factory spec sheet lists an optimal flow of 80 L/min (21.1 gpm) at 230 bar (3336 psi); dealer listings give a broader working range of roughly 76-87 L/min (20-23 gpm) at about 193-228 bar (2800-3300 psi). Treat the exact figure as varying by carrier configuration and hydraulic package.
Rated carrier models
Documented compatible carriers include the 236D, 246D, 257D, 259D, 262D, 272D, 272D XHP, 277D, 279D, 287D, 289D, and 299D/299D XHP skid steer and compact track loaders, plus the 906H2, 907H2, and 908H2 compact wheel loaders. Newer-generation coverage extends to the 226D3 through 299D3 skid steer/CTL range and the 906-908 compact wheel loader series.
Conversion kit requirement
A conversion kit is required to fit the SR118 to D Series and H Series 2 carrier models, indicating the base coupler configuration is not directly interchangeable across all listed carrier generations without it.
Factory configuration options
Standard equipment includes a bolt-on reversible cutting edge and adjustable skid shoes that let the operator set cutting-edge height for the job surface. The auger and impeller are reversible from the cab to clear obstructions without dismounting.
Chute and control options
The discharge chute rotates 270 degrees, directing snow to the front or either side to reduce blow-back toward the operator. Chute and deflector are run through the carrier's own joysticks with no separate wiring or hardware needed, and a chute-mounted grab handle plus grated steps aid entry and exit.

SR118 serial number reference
The PIN plate on the SR118 is mounted on the attachment frame near the SSQA mounting plate/hitch end, the same area used on other Cat SSQA-mount work tools. Read the first 3 characters as the serial prefix (identifies model/family and plant) and the following digits as the sequential unit number; the format follows Cat's standard PIN layout rather than a model-year code.
| Prefix | Identifies | Notes |
|---|---|---|
| SNB | SR118 (shared family prefix) | SNB00001-UP is documented in the Cat electrical system manual as covering the SR117, SR118, SR121, SR318 and SR321 snow blowers together, with no model-specific sub-range broken out. A separate Cat parts manual groups SR115, SR118, SR121, SR318 and SR321 under the same document without listing distinct per-model prefixes either. Treat SNB as the entire attachment family's prefix, not an SR118-exclusive range; confirm the specific unit's build/engine fitment with a dealer using the full PIN. |
Frequently asked questions
What hydraulic flow and pressure does the Cat SR118 need?
The SR118 is rated for roughly 76-87 L/min (20-23 gpm) of auxiliary hydraulic flow, with an optimal point near 80 L/min. Pressure runs in the 200-230 bar (2800-3300 psi) range depending on carrier and circuit configuration. Running below this window underpowers the auger and impeller in heavy snow; running above it stresses the chain drive and hydraulic motor.
What is the SR118's operating weight?
The SR118 weighs approximately 433 kg (954 lb) in standard configuration. Exact weight varies slightly with mounting plate and any factory-fitted options.
What carriers is the SR118 rated for, and has it been replaced?
The SR118 is built for Cat's 226D3-299D3 skid steer and compact track loader range and the 906-908 compact wheel loaders. Older D-Series and H-Series 2 carriers need a separate conversion kit to run it. It remains part of Cat's current snow blower lineup alongside the SR115, SR117, SR121, SR318, and SR321; no confirmed successor model has replaced it.
