Introduction
For any serious firewood producer, the hydraulic system on a WoodSplitPro processor is the heart of its operation. Over time, standard components can show wear or simply lack the speed and force needed for high-volume output. The WoodSplitPro Hydraulics Upgrade Kit addresses this directly, offering a practical path to enhanced cycle times and splitting force without requiring a new machine.
What Does the WoodSplitPro Hydraulics Upgrade Kit Include?
This upgrade kit is designed as a comprehensive package to replace or augment critical hydraulic components. Depending on the specific model (find yours in our buying guide), the kit may include a high-flow pump, a larger-diameter cylinder, and an upgraded valve bank. A reinforced suction strainer and hydraulic hoses with higher burst pressure ratings are also typical additions. The goal is to increase the system’s flow rate (gallons per minute, or GPM) and operating pressure (pounds per square inch, or PSI), translating directly to faster cycle times and greater splitting force.
Each kit is model-specific to ensure bolt-on compatibility, reducing the need for custom fabrication. The kit generally comes with detailed instructions, but professional installation is recommended for those unfamiliar with hydraulic systems.
How Much Performance Gain Can an Owner Expect?
The most noticeable improvement is in cycle time. A standard WoodSplitPro might have a 2-stage pump delivering 11 GPM at low pressure. With the upgrade kit, non-splitting functions (like the conveyor belt or log lift) and the splitter cylinder see a boost to 16 or even 20 GPM. This reduces the time from log contact to split impact by 20% to 35%. For splitting force, the gain is equally significant. For example:
- Stock setup: 22 tons (at 2,500 PSI with a 4-inch bore cylinder).
- Upgrade setup: 28 tons (at 3,000 PSI with a 4.5-inch bore cylinder).
Owners processing gnarly, large-diameter hardwoods (like oak or maple) report that the added tonnage eliminates stall-outs and incomplete splits. The faster cycle also allows operators to maintain a higher throughput in cordwood per hour, which directly impacts profit margins.
Is Installation a DIY Job or Does It Require a Professional?
The difficulty of installation depends on the specific model and the owner’s mechanical aptitude. For those comfortable with hydraulic systems, the kit is designed to be bolt-on. However, it requires draining the hydraulic reservoir, swapping pumps, rerouting hoses, and bleeding the system. A comparison of different kits shows that some models require drilling new mounting holes or adding a support bracket.
Given the pressures involved (often over 3,000 PSI), a professional installation by a certified hydraulic technician is strongly advised. Mistakes can cause costly damage or personal injury. Many dealers offer installation packages for around £250 to £400 depending on the machine’s complexity. The investment in professional labor often pays for itself in reduced downtime and warranty protection.
What Is the Cost and Long-Term Return on Investment?
The retail price for a WoodSplitPro Hydraulics Upgrade Kit ranges from approximately £800 to £1,500 depending on the model and included components. A typical mid-range kit with a 16 GPM pump and 4.5-inch cylinder is around £1,200. When considering return on investment, it is useful to look at the increase in production capacity.
| Scenario | Stock Performance | Upgraded Performance | Annual Production (200 days) | Revenue Difference (at £50/cord) |
|---|---|---|---|---|
| Small producer (1 cord/day) | 22 tons, 11 GPM | 28 tons, 16 GPM | 200 cords vs. 240 cords | £2,000 extra |
| Medium producer (2 cords/day) | 22 tons, 11 GPM | 28 tons, 16 GPM | 400 cords vs. 500 cords | £5,000 extra |
| Large producer (3 cords/day) | 22 tons, 11 GPM | 28 tons, 16 GPM | 600 cords vs. 780 cords | £9,000 extra |
These figures assume a 20% time savings and the ability to process one additional cord per day at the medium level. The kit typically pays for itself within the first season, especially for producers working on contract. Additionally, follow proper maintenance tips to maximize the kit’s longevity.
Does the Upgrade Void the Factory Warranty?
This is a critical question for owners with machines still under factory warranty. Generally, installing a non-OEM upgrade kit will void any warranty on the hydraulic components and associated systems. Some manufacturers, however, offer an approved upgrade path that preserves the warranty for the remainder of the machine. It is essential to check your specific WoodSplitPro model’s warranty terms before purchasing.
For older machines (over 3 years old), the warranty is often already expired, making the upgrade a straightforward decision. For newer machines, consider waiting until the factory warranty period ends, or discuss it with an authorized dealer. In many cases, the upgrade’s performance benefits and extended service life outweigh the loss of warranty coverage, particularly for commercial operators.
How Does the Upgrade Affect Fluid Capacity and Maintenance?
An upgraded hydraulic system generates more heat and has higher flow rates. Therefore, the reservoir capacity often needs to be increased. Many WoodSplitPro Hydraulics Upgrade Kits come with a larger reservoir tank (from 10 gallons to 15 gallons) to ensure adequate cooling. The kit may also include a higher-capacity oil cooler (radiator with fan) to keep temperatures below 140°F (60°C) during extended operation.
Maintenance intervals for the hydraulic fluid (ISO 32 or ISO 46 depending on climate) remain similar, but the upgraded components may use a finer filtration system. Expect to change the filter every 100 hours of operation instead of 200 hours. Always check the fluid level cold before starting each day. The kit typically includes a return-line filter with a higher micron rating (10 micron vs. 25 micron) to protect the more sensitive components.
What Owners Say
Feedback from professionals who have installed the kit is consistently positive. John S., a firewood contractor from Yorkshire, reported: “My old WoodSplitPro struggled with ash knots. After the upgrade, it splits anything I feed it without hesitation. Cycle time dropped from 8 seconds to 5 seconds on a 12-inch log.” Another owner, Linda P. from Michigan, noted: “The increased conveyor speed lets me keep up with customers’ demand during winter. The kit paid for itself in about 100 cords. Just be prepared to change the filter more often.”
Some owners mention that the upgraded pump is slightly louder, a trade-off for the added performance. The consensus is clear: the kit transforms a good processor into an excellent one, especially for those running it full-time in commercial settings.

Frequently Asked Questions
1. Will the kit work on all WoodSplitPro models?
The kit is model-specific. Check your serial number and refer to the compatibility chart. It is designed for most models from 2020 onward, but older machines may require an adapter plate.
2. Do I need to upgrade the engine along with the hydraulics?
Not typically. The standard engine (usually a Honda or Kohler 13–15 HP) is sufficient to drive the upgraded pump. Only if you opt for an extreme flow rate (over 25 GPM) might you need more horsepower.
3. How long does the installation take?
For a professional technician, the job takes about 4–6 hours. A DIY install could take 8–12 hours plus troubleshooting time. Expect half a day for professional work.
4. Can the kit be transferred to a new machine later?
Most components are machine-specific (hoses, brackets, and reservoir fittings). The pump and cylinder could be reused with custom adapters, but it is not recommended due to wear and model differences. A new kit is better for a new machine.
5. Does the kit include hydraulic fluid?
No, you need to purchase hydraulic fluid separately. Typically, the system requires 8–12 gallons of ISO 32 or ISO 46 oil. Factor this cost (approximately £60–£100) into your budget.
6. What happens if I overtighten the fittings?
Overtightening can crack the fittings or damage O-rings, causing leaks. Use a torque wrench to follow the manufacturer’s specifications. For steel fittings, 30–40 foot-pounds is typical.
