Section 5: Maintenance/Repairs

WARNING Before inspecting, cleaning or servicing the unit, shut off engine, wait for all parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key on electric start models. Failure to follow these instructions can result in serious personal injury or property damage.

INSPECTING / REPLACING THE DRIVE BELT

The drive belt can be inspected or re- placed from beneath the machine deck.

The belt should not require inspection for many hours of operation. If re- placement becomes necessary, follow the instructions given here.

Belt Inspection

Stop the engine and let all moving parts stop. Disconnect the spark plug wire and move it away from the spark plug. Remove the ignition key on elec- tric start models.

A.For your convenience, we recom- mend that you place the trimmer/ mower on a raised platform to make access to the underside of the deck as easy as possible.

B.Remove the rubber debris flap (A, Figure 5-4) by using pliers to remove either one of the small E-rings (B) at the ends of the retainer rod and then sliding the retainer rod out.

C.Remove the rear belt cover by using a 1/2" wrench to remove the sin- gle screw (C, Figure 5-4) in the rear belt cover. Examine the belt carefully. Feed it around the rear pulley so the entire belt can be examined. If cracks or other damage are noted, a new belt is needed. Otherwise, clean and re- place the belt cover and debris flap.

Belt Replacement

E.With a 1/2" wrench, remove the screw (D, Fig. 5-4) securing the front belt cover/spindle mounting plate. Then remove the other four screws holding the belt cover/spindle mount- ing plate on (E, F, G and H, Fig. 5-4). Lower the drive housing and the belt cover/spindle mounting plate carefully. Note precisely how the belt is routed along the pulleys. (See Figure 5-7.) Work the belt off the rear pulley (H, Figure 5-7), then off the other pulleys. NOTE: The nut on the idler arm V-pul- ley must be removed in order to take off the belt. The screw may need to be held with an allen wrench. Install the new belt along the very same path.

F.Clean parts of all debris. Replace the lower driveshaft housing and front belt cover/spindle mounting plate, the spindle head, the wear cup, the rear belt cover and the debris flap.

G.Check for correct belt tension. See “Adjusting Trimmer Head Engagement” in this Section.

Be sure to align one of four holes in the pulley with the deck hole first.)

52051, 52052 specifications

Troy-Bilt has long been recognized for its commitment to quality and innovation in outdoor power equipment, and the Troy-Bilt 52052 and 52051 models are no exception. These garden tillers are designed to tackle a variety of tilling tasks, making them suitable for both novice gardeners and seasoned horticulturists.

The Troy-Bilt 52052 features a robust 4-cycle engine, which provides ample power to tackle tough soil conditions. With a displacement of 196 cc, this model is equipped to till soil up to 10 inches deep, ensuring that nutrients can be effectively mixed into your garden bed. The 52051 shares similar characteristics but is tailored for slightly different gardening needs. Both models feature an adjustable tilling width, allowing users to customize their tilling experience, with widths ranging from 16 to 21 inches. This versatility enables gardeners to efficiently navigate tight spaces or cover larger plots in fewer passes.

One of the standout technologies integrated into these models is the "Rear-Tine" design, which allows for smoother operation and superior maneuverability. This design feature not only enhances ease of use but also reduces strain on the user, making gardening tasks less daunting. The counter-rotating tines of the tillers are specifically designed to break up hard soil, allowing for effective aeration and preparation of planting beds.

Both models excel in terms of convenience, featuring a user-friendly starting system. The push-button electric start on the 52052 is particularly beneficial for those who may have difficulty with traditional pull-start mechanisms. Additionally, the tillers are designed with ergonomic controls, ensuring that users can operate them comfortably for extended periods.

Durability is another hallmark of the Troy-Bilt brand, and these tillers are constructed with high-quality materials to withstand the rigors of regular use. The heavy-duty steel tines are built to last, and the sturdy frame ensures stability while in operation.

In summary, the Troy-Bilt 52052 and 52051 garden tillers combine power, versatility, and user-friendly features, making them excellent choices for anyone looking to enhance their gardening experience. With their advanced technologies and robust construction, these tillers promise to deliver outstanding performance for all your gardening needs.
