Question: Trimmer Haed Removal

Henry

How do I remove trimmer head to replace string? The retainer nut seems to have been seized since I purchased it 5 years ago, I gave up on it until I found this web site. Help?

Question: Brushes

Kurt

Love this thing! Now going on five years. I keep it going using this site and buy what it needs to survive. I don't see motor brushes listed. I can't see replacing the entire motor just for brushes. Can I get replacements?

Question: Shuts Off

jay

When I hit the power switch it only turns about 1/4 turn then shuts off. Would that be the switch or the motor?

Question: Dead Trimmer

jim t

Cutting down long grass and trimmer went dead. Would this be a switch assembly or a total motor burn out. Is there an overload fuse. Thanks Jim T

Hi Jim,

It could be the cord, the switch or the motor. You can test the cord and switch with a multimeter set to test impedance. (ohms) If the cord and switch test out OK then the problem is likely with the motor. You will need to take the motor to a repair shop to be tested.

The cord is part #UT41002A-31, the switch is part #UT41002A-38, and the motor assembly is part #099015003006. All of these parts are available from http://ereplacementparts.com.

Good luck with your repair!

This a reply to my own question. I took trimmer apart carefully. A bunch of small screws and one large one. I then took several digital photos of wiring and locations of items. You can zoom in later if needed. Pay attention to wiring. I then bypassed switch with power wires. The motor ran. Its the switch assembly ! Ordered 2 just in case. Switch assembly is 10.5 Amp. The motor is only 6 AMP. Do not know why it went out. Would not increase amps, if motor burns out $55 , Its cheaper to buy reconditioned unit. Thanks for responding ! Thanks !

Question: Checking The Motor

linda

how do i check if the motor on the RY41002 trimmer has gone bad or if it is just the switch?

Reply: Checking The Motor

Mark

Hi Linda,

You won't be able to test the motor without specialized equipment but you can definitely test the cord and switch. If the cord and switch are OK you can pretty safely assume that the motor is bad. You can test the switch and cord with a multimeter set to measure impedance. (ohms) Check continuity through the cord then through the switch. If both test OK the problem is most likely with the motor.

The cord is part #UT41002A-31, the switch is part #UT41002A-36 and the motor is part #099015003006. All of these parts are available from http://ereplacementparts.com.

I hope this helps with your repair!

Question: RYOBI STRING TRIMMER REPAIR

CHARLES

After reading some questions on the forum I see the need to rephrase my question. I have a RYOBI R41002 electric string trimmer that had several switch assembly failures while under warranty and has now failed again (out of warranty). I want to replace the switch/spring/trigger myself and wonder what will happen when I separate the halves of the housing. Is anything likely to go flying off or should everything stay in place provided I am careful? I've had experience over the years repairing various things so I'm not a beginner.

Any thoughts/comments/advice will certainly be appreciated.

Thank you.

Very easy - I just did this. Lots of screws but the halves separate easily. Just make sure you see the wire routing path. The switch itself has a spring but it doesn't pop out when you take the side off.

Bob

Nothing will fall out. Take it apart with all of the screw holes on top just like you unscrew it. I think what makes the switches go out so often is using a cord that is to long or the wire gauge is to small. But that is just a guess.
Good Luck

Question: SWITCH REPLACEMENT

CHARLES

Can the switch and trigger assembly on a RYOBI RY41002 be replaced without removing the motor assembly?

Hi CHARLES88,

I don't think you will have much trouble at all. There is a spring that goes between the switch lever and the switch you will need to be a bit careful with but other than that I think it will be a pretty straight forward repair. Here is a link to the parts diagram...

Link to Ryobi RY41002 trimmer.

The spring you need to be aware of is item #8 on the parts diagram.

Good luck with your repair!

Charles, Please let me know how you did. I have the same trimmer and same history. Too bad they didn't do a recall with a better switch unit to replace it with.
John :)

Also, please let me know what parts you ordered to fix yours with. I am unsure exactly what parts fail. :rolleyes:

I finally ordered replacement parts for my trimmer and received them a couple of days ago. On Tuesday night I sat down, disassembled the unit and replaced the switch. It turned out to be about a 30 minute job (Went slow and "measured twice and cut once" as the saying goes). I did not consider it difficult. Although I ordered the switch, trigger and spring (Part numbers 6, 7 and 8 on the parts explosion diagram) I decided to replace only the switch. I took it outdoors next day, started it up and trimmed enough grass and weeds to allow me to declare the repair a success.

Based on my past failure rate I ordered three of each part, so I should be covered for the next three years. From a practical point of view the switch appears to be the weak point but the other two parts were inexpensive and I'll have them just in case. The new switches had a different manufacturer's part number stamped on them, hopefully denoting a 'new and improved' version. I have no idea how long these switches will be available through Ryobi channels but hopefully they are an off-the-shelf electronic item.

I would like to thank Jim and UtahAV for words of encouragement on this repair and apologize to joeblough for not doing this sooner so I could answer his questions. I'm not rude, just slow.

Review: Ryobi - RY41002 2 Time Owner

Bryan

This is the 2nd RY41002 that I have owned. I have a huge yard that I have to use my trimmer on about every 6 days 10 months out of the year. This is by far the best trimmer I have ever used, and I have been using trimmers of varying styles since the gas Sears Weedeaters of the 80's. This has the power of a gas w/o the vibration and noise. It just lays to waste anything I throw at it. My only complaint is that when I wore the last one out, I could not find a new one, I had to buy refurbished. I don't understand why they were discontinued. Love it!
