8.Install thrust bearing (12) onto the end of coupling shaft (11).

9.Apply a small amount of clean grease to a new seal ring (5) and insert it into the housing (3) seal ring groove.

Note: One or two alignment studs screwed finger tight into housing (18) bolt holes, approximately 180 degrees apart, will facilitate the assembly and alignment of com- ponents as required in the following procedures. The studs can be made by cutting off the heads of 3/8±24 UNF 2A bolts so they are 0.5 inch (12.7 mm) or longer than cap screw (14).

Note: Use any alignment marks put on the coupling shaft (11) and drive link (13) before disassembly to as- semble the drive link splines in their original position in the mating coupling shaft splines.

10.Install drive link (13) with the long splined end down into the coupling shaft (11). Engage the drive link splines so they mesh with the coupling shaft splines (Fig. 47).

11.Assemble wear plate (18) over the drive link (13) and alignment studs onto the housing (3).

12.Apply a small amount of clean grease to a new seal ring (5) and assemble it into the seal ring groove on the wear plate side of the stator (21).

Note: The rotor set consists of the rotor (19), vanes (20), and stator (21). Rotor set components may be- come disassembled during service procedures.

Note: It may be necessary to turn one alignment stud out of the housing (3) temporarily to assemble rotor set over the drive link (13).

Note: The rotor set rotor counterbore side must be down against wear plate for drive link clearance and to maintain the original rotor±drive link spline contact. A ro- tor set without a counterbore and that was not etched before disassembly can be reinstalled using the drive link spline pattern on the rotor splines if apparent, to de- termine which side was down. The rotor set seal ring groove faces toward the wear plate (18).

13.Install assembled rotor set onto wear plate (18) with rotor (19) counterbore and seal ring side down. The splines should mesh with the drive link (13) splines.

14.If disassembled rotor (19), stator (21), and vanes (20) cannot be readily assembled by hand, assemble with the following procedures:

A.Place stator (21) onto wear plate (18) with seal ring (5) side down. Be sure the seal ring is in place.

B.If assembly alignment studs are not being uti- lized, align stator (21) bolt holes with wear plate (18) and housing (3) bolt holes. Screw two cap screws (14) finger tight into bolt holes approximately180 de- grees apart to retain stator and wear plate station- ary.

Note: If the manifold (22) side of the rotor (19) was etched during wheel motor disassembly, this side should be up. If the rotor is not etched and does not have a counterbore, use the drive link spline contact pattern apparent on the rotor splines to determine the rotor side that must be against the wear plate.

C.Place rotor (19) with counterbore down, if appli- cable, into stator (21), and then onto wearplate (18) so rotor splines mesh with drive link (13) splines.

IMPORTANT: Do not force rotor vanes into place, the coating applied to stator vane pockets could shear off.

D.Assemble six vanes (20), or as many vanes that will readily assemble into the stator vane pockets.

2600D, 2300-D specifications

The Toro 2300-D and 2600-D are industry-leading reel mowers specifically designed for the professional turf care market. Known for their durability, efficiency, and advanced technology, these models provide exceptional cutting performance for golf courses, sports fields, and other high-quality turf applications.

One of the standout features of the Toro 2300-D and 2600-D is their powerful engines. Powered by efficient diesel engines, these mowers deliver robust performance while being fuel-efficient. This capability ensures extended operation periods, allowing grounds crews to maintain pristine conditions across large areas without frequent refuelling stops.

Both models are equipped with Toro’s exclusive DPA (Dual Precision Adjust) cutting system, providing precise cutting heights for optimal turf health. This system allows for adjustments from 1/8 inch to 1 inch, enabling operators to achieve the correct level for various grass types and turf conditions. This level of precision ensures a clean cut and promotes the overall health of the grass.

Another notable characteristic is the ergonomic design, which includes a comfortable operator station to reduce fatigue during extended use. The controls are intuitively located, enabling easy access and operation, and the mower's compact design allows for nimble maneuverability around obstacles, ensuring that every inch of turf can be accurately maintained.

In terms of technology, the Toro 2300-D and 2600-D feature advanced traction control systems that provide excellent grip and stability on slopes and uneven terrain. The lightweight alloy construction of the frame contributes to this stability, giving operators confidence whether they are working on flat surfaces or more challenging landscapes.

Furthermore, these mowers are designed with sustainability in mind. The diesel engines not only offer efficiency but also are compliant with strict emissions standards, making them an environmentally responsible choice for turf maintenance.

The Toro 2300-D and 2600-D also feature a robust maintenance management system that alerts operators of necessary maintenance tasks, promoting longer lifespans for components and enhancing overall performance.

In summary, the Toro 2300-D and 2600-D deliver cutting-edge technologies and features, including powerful engines, versatile cutting systems, ergonomic design, advanced traction control, and sustainability focus. These models represent the pinnacle of reel mower engineering, making them ideal choices for professionals dedicated to maintaining the finest playing surfaces.
