How do I request a quotation for service kits, and how quickly do you reply?

Send the machine model and serial number, the hour meter reading, the engine and hydraulic brands if they differ from the machine brand, the number of machines of each type, the quantity of kits, and the destination port through the contact page of Guangzhou Shenyue Machinery Technology Co., Ltd. Quotations normally come back within 24 hours, with filters, oils, seals and wear items priced on separate lines and the filter grade stated for each line.

Is it cheaper to buy filters in a kit than one at a time?

Yes, for two reasons. The unit price drops because the order is larger and the lines are consolidated, and the freight drops because one shipment replaces several. A mixed-brand fleet that consolidates three months of service parts into one container typically sees the largest saving of any single change to its purchasing.

Should service kits use genuine filters or aftermarket ones?

Both are supplied, and the choice is stated per line. Genuine filters keep a machine inside a dealer warranty and are the safe default for common-rail fuel systems. A reputable aftermarket line is normal practice for engine oil, hydraulic return and pilot filters once the machine is out of warranty. Guangzhou Shenyue Machinery Technology Co., Ltd. labels every line genuine, OEM-quality or aftermarket so the buyer decides with the price in front of them.

Excavator Scheduled Service Kits: What Belongs in a 500, 1,000 and 2,000 Hour Kit, and How to Buy Them

Most excavator fleets buy service parts the way they buy fuel - one fill at a time. The cost is not the price of the filter; it is the number of separate shipments, the number of people handling each one, and the fraction of a service that gets deferred because one element was not on the shelf. Interval kits fix that, and they are the easiest purchase a fleet can consolidate. This guide sets out what belongs in a 500, 1,000 and 2,000 hour service kit, how kits differ between machine classes and engine brands, and what to send to have a mixed-brand fleet quoted in one shipment. Guangzhou Shenyue Machinery Technology Co., Ltd. builds these bundles from its Guangzhou warehouse.

Corbay is the international export brand of Guangzhou Shenyue Machinery Technology Co., Ltd., Guangzhou, China. The company has supplied excavator parts since 2007, keeps 3,000+ part types on the shelf and 100,000+ part numbers available to order, and serves customers in more than 30 countries.

What Belongs in a 500 Hour Kit

Engine oil filter and engine oil.The core of the interval. Specify the oil grade by the manual, not by habit.

Water separator and primary fuel filter.Water in diesel is the single most common cause of injector damage on common-rail engines.

Inspections that need parts on hand.Belts, hoses, battery terminals and hose clamps - small items that stop a service from finishing.

Grease and bucket pin inspection.Cheap consumables that determine how long the expensive parts last.

What Belongs in a 1,000 Hour Kit

At 1,000 hours the kit grows to include the hydraulic return filter or the suction strainer, the pilot line filter, the air filter elements in pairs, the breather on the hydraulic tank, and a hydraulic oil sample. This is the interval where deferred maintenance shows up: a machine that skipped the 500 hour fuel filters arrives with a contaminated rail, and the repair costs more than five years of filters. For machines working in dust, quarry or demolition conditions, the air filter element must be added earlier than the book suggests and the kit should carry a spare.

What Belongs in a 2,000 Hour Kit

The 2,000 hour service mixes filters with wear parts: hydraulic oil and full hydraulic filter set, a complete coolant change with the conditioner the engine maker specifies, differential and swing gear oil, final drive oil, and inspection of the undercarriage, pins and bushings. It is also the point at which most operators plan the items that are cheaper now than later - the fan belt, the thermostat, the water pump if the hours are close, and engine mounts. Bundling the 2,000 hour parts into one quotation is what allows a fleet to compare genuine and OEM-quality options on the whole service rather than arguing about one filter.

Why Interval Kits Cost Less

One shipment instead of six.Freight is often the largest line in a small parts order.

Better unit prices.Consolidated lines move the order into a different price bracket.

No deferred items.A kit that arrives complete means the service finishes, and skipped intervals are what create breakdowns.

Predictable budgeting.A cost per hour figure per machine class is easier to defend than a month of ad-hoc invoices.

Kits for a Mixed-Brand Fleet

Real fleets are rarely uniform. A yard may run a Kobelco SK200-8 with a Hino J05E, a Komatsu, a Hitachi, a Doosan and two Chinese machines, each with its own filter set and its own oil specification. The efficient approach is to build a kit per machine type, group them by interval, and quote the whole fleet in one list - which is what Shenyue Machinery does routinely, because a single warehouse holding engine, hydraulic, filter, seal, undercarriage, electrical and cab parts can serve every brand on the yard in one consignment. Hino publishes its engine service documentation through hino-global.com, which is useful when a fleet standardises on J05 or J08 powered machines.

How to Buy It

Send the machine list.Model, serial number and hour meter reading for each machine, plus the engine brand if it differs.

Say which interval you are planning.500, 1,000 or 2,000 hours, and how many machines of each type.

State the grade you want.Genuine, OEM-quality or aftermarket, or ask for all three on the same list.

Give the destination port.Air for breakdowns, sea for planned kits, and the quotation will show both.

Service Kits - FAQ

Can you write a kit for a machine you have not supplied before?Yes. Send the model, serial number, hour reading and photographs of the filters currently fitted, and the kit will be assembled from those.

How often should hydraulic oil be sampled?At every service from 1,000 hours is a sound working rule, and always after a pump or cylinder repair. Sampling costs less than the oil it protects.

How do I request a quotation and how fast is the reply?Send the machine list, intervals, quantities and destination port through the contact page - Guangzhou Shenyue Machinery Technology Co., Ltd. normally replies within 24 hours with the bundle priced line by line.

Buy the Interval, Not the Single Part

A service kit is the cheapest way to convert maintenance from a series of emergencies into a plan. Build one kit per machine type, quote the whole fleet at once, and send the machine list to the team at Guangzhou Shenyue Machinery Technology Co., Ltd. The kits will be assembled, priced by grade, and photographed before they leave Guangzhou.
