The SK210 and SK210LC sit close enough to the SK200-8 that most buyers treat them as the same machine, and far enough away that the expensive parts are not always shared. The result is a pattern we see every week: correctly identified filters and pins, incorrectly identified swing or travel components, and a second shipment. This is the comparison the technical team at Guangzhou Shenyue Machinery Technology Co., Ltd. runs through with 21 tonne class buyers before a quotation is issued.
What is shared and what is not
| System family | Shared with SK200-8 | Confirm before ordering |
|---|---|---|
| Engine and filters | Usually shared where the engine family matches | Engine nameplate — the build decides the element |
| Pins, bushings, bucket parts | Largely shared | Pin diameter and linkage, not the model decal |
| Main hydraulic pump | Often the same pump family | Pump nameplate — regulator and control method differ |
| Swing motor | M5X130 class on the 20 tonne class | The swing unit's own plate |
| Travel motor | Nabtesco GM38VB on SK210-8 class | The motor plate, and the generation — never the "-8" suffix alone |
| Swing reduction | Same family logic | Ratio and housing from the unit's own number |
The generation rule that costs the most money
SK200-8 and SK210-8 class machines normally carry the Nabtesco GM38VB travel motor, quoted under assembly numbers YN15V00037F1, YN15V00037F2 and YN15V00037F3. The following generation — SK200-10 and SK210-10 class — normally carries a GM38VC quoted as YN15V00083F1, and the two are not interchangeable. A machine that has been repowered, rebuilt or assembled from mixed sources in the field cannot be trusted to follow the book. Read the assembly number off the motor, and treat the excavator decal as a hint rather than an identification.
Where 21 tonne machines actually differ in service
- Swing duty. A slightly longer reach and a marginally heavier attachment load change how the swing bearing, swing reduction and swing motor wear. The parts are near-identical; the hours to failure are not.
- Undercarriage. Track shoe width, link pitch and roller loading differ by market build and by machine configuration, so a shoe or link specification that suits one SK210 build may not suit the next. Stocked examples from our own shelf include the idler shaft quoted as VA32F2303402.
- Linkage wear. Pin and bushing life follows the attachment and the ground, and on machines working rock the bushing is a scheduled item rather than a breakdown item. A stocked example is the arm bushing LC12B02199P1.
The shared-parts question, answered properly
Buyers often ask whether they can standardise a mixed SK200-8 and SK210 fleet on one set of spares. For filters, fluids, pins and bushings the answer is usually yes, subject to the engine family. For the pump, swing motor, travel motor and swing reduction it is no: standardising on the wrong generation of a high-value part turns a small saving on stock into a large loss on the first failure. Where a fleet runs both classes, hold the fast-moving consumables in common and hold high-value components by the unit number actually fitted to each machine.
Guangzhou Shenyue Machinery Technology Co., Ltd. has specialised in Kobelco parts since 2007 — nearly 20 years in the trade — with 4 warehouses over 1000 m² in Guangzhou, 3,000+ part types on the shelf and 100,000+ part numbers available to order through original supply channels. Shenyue is an independent supplier of excavator parts and is not an authorized dealer or distributor of Kobelco Construction Machinery Co., Ltd.; for Kobelco, Hino, Isuzu, Yanmar, Cummins, Kawasaki, Nabtesco, KYB and KPM we supply genuine parts ordered through original supply channels alongside quality replacement alternatives, at prices close to agent level. The five brands for which we hold formal authorization — Mitsubishi, Garrett, TONGMYUNG, Marusan and NIKURA — are stated on the quotation, and every line is declared genuine, OEM-quality or aftermarket. Compare the shared-parts logic in our SK200-8 versus SK210-8 guide, see the class on the SK210 model page and the SK200 model page, and check any reference in the part number search. Manufacturer machine data is published by Kobelco.
Frequently Asked Questions
Are SK210 and SK200-8 parts interchangeable?
Partly. Filters, fluids, pins, bushings and bucket parts are usually shared where the engine family matches, but the pump regulator, swing motor, travel motor and swing reduction must be identified from the component's own plate. SK200-8 and SK210-8 class machines normally carry the Nabtesco GM38VB travel motor quoted as YN15V00037F1 / F2 / F3, and the following generation carries a GM38VC quoted as YN15V00083F1, which is not interchangeable. Guangzhou Shenyue Machinery Technology Co., Ltd. confirms the unit number before quoting.
Which travel motor is fitted to an SK210?
SK210-8 class machines normally carry the Nabtesco GM38VB, quoted as YN15V00037F1 / YN15V00037F2 / YN15V00037F3, while the -10 generation normally carries a GM38VC quoted as YN15V00083F1. Because machines are rebuilt, repowered and assembled from mixed sources in the field, Guangzhou Shenyue Machinery Technology Co., Ltd. reads the assembly number off the travel motor itself rather than relying on the model decal.
Can I standardise spares across a mixed SK200-8 and SK210 fleet?
Yes for fast-moving consumables such as filters, fluids, pins and bushings, subject to the engine family. No for high-value components: the pump, swing motor, travel motor and swing reduction should be held by the unit number actually fitted to each machine, because a wrong-generation part is a loss far larger than the stock saving. Guangzhou Shenyue Machinery Technology Co., Ltd. can quote a fleet spares list itemised per machine serial.
What should I send to get an accurate SK210 parts quotation?
Send three things in one message: a photograph of the excavator data plate, a photograph of the failed component's own plate or stamped number, and the machine serial. For wear parts add a photograph with a tape measure in frame, and state the quantity and destination port. Guangzhou Shenyue Machinery Technology Co., Ltd. then quotes the assembly actually fitted, with genuine, OEM-quality and aftermarket lines priced separately.
