What parts and equipment does Jumanje support?
We specialize in aftermarket diesel engine parts for Cummins-related engines and provide broad cross-brand support for Komatsu, Case, JCB, FAW, TATA, and Perkins equipment. Our inventory includes turbochargers, belts, filters, engine rebuild components, and generator parts. We serve agriculture, construction, mining, earthmoving, industrial, marine, and power generation sectors across South Africa.
How do I determine if a part is compatible with my equipment?
Compatibility depends on your specific engine model, year, and application. We recommend contacting our team with your equipment details—engine serial number, brand, and model are most helpful. Our technical team will confirm compatibility and help you source the correct part. If you're unsure, call 060 525 9943 and we'll guide you through the process.
What is your sourcing and procurement process?
When you submit a parts inquiry, our team reviews your requirements and leverages our distributor relationships to locate the part. We confirm availability, compatibility, and pricing, then coordinate delivery. Our 25+ years of industry relationships mean we can often source components faster than you might expect—even hard-to-find parts. The timeline depends on part availability and your location within South Africa.
How long does it typically take to source a part?
Timeframes vary based on part availability and complexity. Common parts in stock can often be arranged within 24–48 hours. Specialized or hard-to-find components may take longer, but our distributor network and technical expertise help us locate parts faster than traditional supply chains. We'll provide a realistic timeline when you submit your inquiry.
Do you support cross-brand equipment and mixed fleets?
Yes. Many operators run mixed fleets with equipment from different manufacturers. We understand this reality and provide cross-brand aftermarket parts support for Cummins, Komatsu, Case, JCB, FAW, TATA, and Perkins equipment. Our expertise spans multiple brands, so you can source parts for your entire fleet from one trusted supplier.
What if I need a hard-to-find or obsolete part?
Hard-to-find parts are where our procurement expertise shines. Our distributor relationships and industry knowledge give us access to specialized sourcing channels. Even if a part is no longer in regular production, we can often locate it or identify a compatible alternative. Submit your inquiry with as much detail as possible—engine serial number, part number, and your application—and we'll explore every option.
How do I submit a parts inquiry or procurement request?
You can reach us in three ways: call 060 525 9943, email sales@jumanje.co.za, or visit our contact page to submit an online inquiry form. When you reach out, include your equipment details, the specific parts you need, and your timeline. The more information you provide, the faster we can respond.
Do you offer technical support or installation guidance?
We provide technical guidance to help you understand parts compatibility and specifications. For installation support, we recommend consulting your equipment manual or a qualified mechanic. However, our team can answer technical questions about the parts themselves—compatibility, specifications, and application. Contact us with your questions, and we'll help where we can.
What are your service areas and delivery options?
We're based in Kempton Park, Gauteng, and serve customers across South Africa. Delivery options depend on your location and the urgency of your parts need. We can arrange local pickup, courier delivery, or regional transport. When you submit an inquiry, discuss delivery options with our team—we'll find a solution that works for your operation.
How do I get a quote or pricing information?
Contact us with your parts specifications and quantity needs. Our team will provide a quote based on current availability and pricing. Call 060 525 9943, email us, or submit an inquiry form on our contact page. We aim to respond quickly with accurate pricing and lead times.

Technical Resources & Compatibility Guides
Understanding parts compatibility and sourcing options is critical when managing mixed equipment fleets. Below you'll find practical technical guidance, compatibility references, and resources to help you identify the right parts for your Cummins, Komatsu, Case, FAW, Perkins, TATA, and JCB equipment.
Cummins Engine Families & Compatibility
Cummins engines span multiple families, each with distinct specifications and compatible aftermarket parts. Understanding which family your engine belongs to is the first step in sourcing the right components.
B Series (Small Displacement): B3.9, B5.9, B6.7 engines commonly found in light to medium-duty trucks, generators, and agricultural equipment. Parts availability is broad; most aftermarket suppliers stock turbochargers, filters, and gasket sets for this family.
C Series (Mid-Range): C8.3, C10, C12 engines used in construction equipment, marine applications, and industrial power generation. Cross-brand compatibility with Case and JCB equipment is common in this range.
ISX Series (Heavy-Duty): ISX11.9, ISX15 engines found in heavy-haul trucks, mining equipment, and large industrial generators. These engines support extensive aftermarket parts networks across turbochargers, fuel systems, and engine rebuild components.
QSK Series (Large Industrial): QSK19, QSK23, QSK60 engines for mining, marine, and power generation. Sourcing parts for QSK engines often requires specialized procurement support due to larger component sizes and longer lead times.
Not sure which family your engine belongs to? Contact our team with your engine serial number or model, and we'll help you identify the correct family and compatible parts.
Cross-Brand Parts Compatibility
Many aftermarket parts work across multiple OEM brands due to shared engine platforms and standardized component interfaces. This is especially true for Cummins-powered equipment from other manufacturers.
Cummins-Powered Equipment: Case, JCB, Komatsu, and other manufacturers often use Cummins engines as their primary power source. Aftermarket Cummins parts (turbochargers, filters, belts) are typically compatible with these branded machines.
Turbochargers: Many turbocharger models are cross-compatible across Cummins B, C, and ISX families. We stock common models used in both original and aftermarket applications. Verify your engine displacement and turbo type before ordering.
Filters (Air, Fuel, Oil): Filter compatibility is largely standardized. Aftermarket filter specifications often match OEM dimensions and threading. We maintain cross-reference charts for common filter sizes across Cummins and other diesel engine brands.
Belts & Drive Components: Serpentine belts and fan belts follow industry standards. Most aftermarket belts are compatible across multiple Cummins engine families. Width, length, and ribbing pattern are the key compatibility factors.
Cross-brand compatibility depends on specific engine model and application. Always verify part numbers and specifications before installation. Our team can confirm compatibility for your mixed fleet.

Specification: Always verify belt width, length, and rib count. Aftermarket belts must match OEM dimensions.
Filter and belt part numbers vary by engine year and configuration. Contact our team with your engine model and serial number for exact specifications and availability.
Generator & Power Generation Component Specifications
Diesel generator sets are critical infrastructure for backup power, mining operations, and remote industrial sites. Component reliability directly impacts uptime and operational cost.
Alternator Components: Voltage regulators, brushes, bearing assemblies, and stator windings. We source OEM-equivalent alternator parts for common Cummins-powered generator sets (10 kW to 500+ kW ranges).
Fuel System Components: Fuel transfer pumps, injectors, fuel manifolds, and supply lines. Generator fuel systems operate under high pressure and require precision components to maintain combustion efficiency and emissions compliance.
Cooling System Parts: Radiators, water pumps, thermostats, and coolant hoses. Generators often run continuously or under sustained load; cooling system reliability is non-negotiable.
Exhaust & Emissions: Mufflers, exhaust manifolds, turbocharger components, and emissions control hardware. Many industrial sites require emissions-compliant equipment; we source parts that maintain OEM specifications.
Control & Monitoring Systems: Engine control modules (ECMs), sensors, wiring harnesses, and digital governors. Modern generators rely on sophisticated electronic control; sourcing compatible electronic components is critical.
Generator downtime is expensive. We prioritize fast sourcing for power generation parts and maintain relationships with suppliers who understand the urgency of backup power restoration.
