Finding the correct Hyundai excavator swing gearbox replacement<\/strong> is more complicated than it should be \u2014 because Hyundai’s own Robex naming convention does not map one-to-one to a single swing gearbox part number. The R130 designation covers at least three different swing gearbox variants depending on production year and market. The R210 sits in a weight class shared with units from other manufacturers that are dimensionally compatible but use different internal configurations. This guide cuts through that complexity: it explains the Hyundai Robex model numbering system, identifies the key differences between the R130, R210, and R290 swing gearbox classes, and explains exactly what information you need before ordering any replacement.<\/p>\n<\/div>\n

Understanding the Hyundai Robex Model Designation<\/h2>\n

Hyundai’s Robex excavator model numbers use a format of R followed by a number indicating approximate operating weight in tonnes \u2014 but this is a rounded approximation, not an exact specification. The R130 is a 13-tonne class machine; the R210 is a 21-tonne class; the R290 is approximately 29 tonnes. Within each class, Hyundai uses a generation letter suffix that changes significantly between production years.<\/p>\n

For swing gearbox replacement purposes, the key factors are the specific model generation and the serial number prefix. Hyundai changed the swing gearbox supplier and design between the LC7 and LCR7 generations of the R210, for example \u2014 two machines that look identical from the outside but use incompatible swing gearboxes internally. Ordering on model name alone, without the serial prefix, is the most common cause of incorrect replacements in the Hyundai aftermarket.<\/p>\n

The generation suffix appears as a number after the model designator. R130LC-9A, R130LC-9S, and R210LC-9 are three different production generations with potentially different swing gearbox part numbers. Always include the complete suffix when requesting a replacement quotation.<\/p>\n

Swing Gearbox Variants by Hyundai Model Class<\/h2>\n

Each Hyundai weight class shares certain physical characteristics that narrow the replacement search before the serial number is confirmed:<\/p>\n

Model Class<\/th>\nApprox. Swing Torque<\/th>\nKey Generations<\/th>\nReplacement Notes<\/th>\n<\/tr>\n<\/thead>\n
R130 \/ R140<\/td>\n7,000\u20139,500 Nm<\/td>\nLC7, LC9, LC9A<\/td>\nTwo flange bolt patterns used across generations. Confirm serial prefix to identify correct output interface. LC7 and LC9 variants are not directly interchangeable.<\/td>\n<\/tr>\n
R210 \/ R220<\/td>\n14,000\u201319,000 Nm<\/td>\nLC7, LCR7, LC9<\/td>\nSwing gearbox supplier changed between LCR7 and LC9 generation. Internal ring gear and planet carrier are not interchangeable between generations even though external dimensions appear similar.<\/td>\n<\/tr>\n
R290 \/ R300<\/td>\n21,000\u201328,000 Nm<\/td>\nLC7, LC9, NLC9<\/td>\nLarger planetary stages with 3-stage reduction. NLC9 (narrow gauge configuration) uses a different output shaft specification from standard LC9. Confirm with serial prefix before ordering.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

The 4 Data Points That Guarantee a Correct Match<\/h2>\n

Regardless of which Hyundai Robex model class you are working on, these four data points allow a supplier to confirm the correct swing gearbox replacement without ambiguity:<\/p>\n

    \n
  1. Complete machine model including generation suffix:<\/strong> For example, “R210LC-9” not simply “R210.” The suffix identifies the production generation and determines which swing gearbox variant was fitted at the factory.<\/li>\n
  2. Machine serial number prefix:<\/strong> The first 5\u20137 characters of the machine serial number identify the production run. Hyundai changed swing gearbox suppliers within the same model generation on several occasions \u2014 the serial prefix is the only reliable way to identify which variant is fitted.<\/li>\n
  3. Existing unit’s part number if accessible:<\/strong> The swing gearbox housing typically carries a stamped or labelled part number. If accessible without full disassembly, this is the most direct confirmation method.<\/li>\n
  4. Output flange bolt circle diameter and pilot hole diameter:<\/strong> Measure these directly on the existing unit if the part number is not accessible. Two digits \u2014 bolt circle PCD and pilot diameter \u2014 combined with the model suffix are sufficient for dimensional confirmation in most cases.<\/li>\n<\/ol>\n

    Common Cross-Model Compatibility Questions<\/h2>\n

    Can I use an R210 swing gearbox in an R220?<\/strong> In many cases, yes \u2014 the R210 and R220 share the same chassis platform in certain generations, and the swing gearbox is dimensionally identical. This must be confirmed by comparing serial prefix ranges, not assumed from model number similarity alone.<\/p>\n

    Are Hyundai and Samsung excavator swing gearboxes interchangeable?<\/strong> Samsung Heavy Industries supplied certain Hyundai models under OEM arrangements in the LC7 generation period. Some Samsung SE210 and Hyundai R210LC7 swing gearboxes share the same external mounting dimensions. Confirm part number before ordering.<\/p>\n

    Can I source the swing motor and gearbox together as a combined unit?<\/strong> Yes \u2014 combined swing motor and gearbox assemblies are available for most Hyundai Robex models. If your swing motor shows contamination from gearbox debris, requesting a combined assembly from one supplier eliminates the risk of seal interface mismatch and simplifies the repair documentation.<\/p>\n

    What to Check Before the Replacement Unit Arrives<\/h2>\n

    While waiting for the replacement to ship, two checks on the machine save installation time:<\/p>\n
