OEM Ryobi Trimmer Parts & Accessories

GUARD ASSEMBLY

$12.70

Fix Number: FIX18784941
Manufacturer Part Number: 351122001

A damaged grass guard may fail to block debris or cut extra trimmer line. First check the guard, line blade, guide wheel, screws, and mounting area. Replace the guard if it is cracked, bent, or missing pieces. Make sure the new guard matches the complete tool model. Turn off the trimmer and remove its battery before starting. The line blade is included, but the guide wheel and mounting hardware are not. Install those saved pieces on the new guard, then make sure everything is tight before use.

COMPRESSION SPRING

$6.51

Fix Number: FIX18788656
Manufacturer Part Number: 679034001

This is a compression spring for trimmers and edgers. The purpose of the compression spring is to provide tension to the trimmer head feed assembly. It is common for this spring to weaken to the point that it is no longer supplying tension. This may become obvious when the trimmer head is feeding line even when it has not been bumped to the ground. For this repair, you will need to remove the head knob, spool, and plastic slider. This should be a fairly quick and simple process that can be done with a screwdriver.

Gear Head

$28.55

Fix Number: FIX12643974
Manufacturer Part Number: 308210009

This Gear gear head assembly is designed to transfer power from the drive shaft to the cutting head, allowing the string trimmer or brush cutter to operate smoothly and efficiently. Housed in a durable gearcase, it supports reliable rotation and helps maintain consistent cutting performance during use. Replacing a worn or damaged gear head can resolve issues such as loss of power to the cutting head, excessive noise, or erratic operation, restoring dependable performance. A properly functioning gear head also helps reduce strain on the drive system, contributing to longer service life and more efficient trimming results.

Plastic Slider w/Metal Insert

$6.51

Fix Number: FIX9939457
Manufacturer Part Number: 310920001

This is the plastic slider for your trimmer. It is made of plastic and metal and is white and color. It measures approximately 2 ½ inches long and 1 inch wide. The slide works with the spool and uses centrifugal force to automatically release the cutting line from the spool. The main reason to replace the slider is if it is damaged or missing, or if the cutting line is not being automatically released. This part is sold individually and is an OEM part sourced directly from the manufacturer.

BUMP FEED TRIMMER HEAD ASSEMBL

$35.15

Fix Number: FIX18784505
Manufacturer Part Number: 314608005

Fix Number: FIX9306452
Manufacturer Part Number: 791-153066B

This bump knob assembly fits lawn and gardening tools, usually trimmers. This part bumps on the ground to advance the cutting line from the spool. With time and use, this part can wear out easily. It is recommended to order an extra knob assembly to always have on hand. Refer to the manual provided by the manufacturer for installation instructions and safety practices.

SLIDER ASSEMBLY

$10.81

★★★★★

1 Review

Fix Number: FIX18784277
Manufacturer Part Number: 310918001

If a trimmer head feels loose or the cutting line stays inside, the slider assembly may be worn. This small piece sits near the spool and helps the line-feed system work. Similar trouble can come from tangled line, a damaged spool, a weak spring, or a cracked cover. Check these items before ordering a new slider. Use the complete tool model number to confirm the correct fit. Remove the battery and wait for the head to stop moving before opening it. Follow the tool diagram because some models require screws or pliers for access. Clean the area, install each piece in the correct order, and test the line feed before trimming.

Installation Instructions

Eleanor from RENO, NV

One diamond on top of auto feeder slide broken off

Packed my patience. Could not find video on how to install new slider kit for an automatic feeder. Blindly removed 14 screws starting with shield and every screw on up the shaft encasing the motor and trimmer line. Then I couldn't pull it apart. Found two labeled areas tgat needed labels cut to split it open. Needed man power. After disassembling, cleaning dread grass away, putting in new unit after removing old unit, reversed my taking apart steps to put together. Ended up with a two inch long compression spring I can not find where it goes. The slider springs are there with the old and new units. Trimmer works okay. My suggestion is have area clean of everything so if an extra part shows up, you know it belongs to what you just took apart. Wish there was a video for auto feed line, not bumper nor gas trimmer, nor making auto feed into a manual feed. Read more...

Line, Fuel Return

$10.25

Fix Number: FIX9137685
Manufacturer Part Number: 791-181086

This is a fuel return line, and it is used with various outdoor lawn equipment. Fuel travels through the return line into the carburetor, and from the primer bulb/pump into the fuel system. The line returns the extra fuel back into the tank. This part will crack and become brittle over time. If your fuel line is leaking, you will need to replace it. Before you begin repair work on your equipment make sure you drain the fuel from the tank, and remove the spark plug.
