Trimmer Repair - Replacing the Piston & Rod Assembly (Ryobi Part # 753-04367)

[@feldmanjared]

The perfect video to complete this task. My trimmer started on the first pull after this part replacement. Thank you!

[@rosschalker6884]

A very clear and easy to understand presentation. Well done!!

[@1234tric]

I would have liked to see a more modern up to date gas weedwacker piston replacement. It presents a different set of problems. Like my screwdrivers were to big to get in the shaft hole to remove the clutch assembly screw. So I used a different method to get to the screws to remove the head. Great videos as always.

[@davidgreenwood4165]

That was excellent. Nothing missed out. Thanks

Great video. Thanks for showing how it’s done. 👍😁

Wonderful video Mark keep it up.

[@AquaCarb]

So helpful I'm just going to buy a new trimmer. My Ryobi has been worked on twice. Each time at a cost of $96 I kept hoping that that next time was thee time. And I had $150 in attachments - Edger and blower - that I didn't want to give up. Now it pulls easy and I'm pretty sure the rings are shot. There are some nice electrics where I dont need to buy gas Im gonna look at.

Great for an old Ryobi but has very little to offer on a newer 252CS trimmer.

[@dntlss]

Man i am restoring one of these right now (troy bilt,but same model) and you have no idea how much this has helped,when i got a hold of this thing the fuel lines had basically disappeared so this gives me a idea how they go,strange thing is as you move the trimmer and the video progresses the lines go from used and old to new and back to old then back to new, did you guys film this at different times?

[@AngelPerez-sx1tm]

Perfect instructions...you are the best bro.

[@kimchee94112]

Didn't he say replace the cylinder at the same time? Warranty was refused on my 2 month old Husqvarna trimmer stating that it had a scorched cylinder and was my fault. No idea what went wrong think it had 5 hours on it, I did put in fresh gas and proper oil mix. That new Husqvarna was going to replace my 30 year old Ryobi I've maintained which still runs pretty good but needed a few pulls before it fires up. Like to get parts and fix it on a rainy day. Anyways got couple of those electric 80V trimmers and couldn't be happier. Only issue was one of the batteries went bad and replaced under warranty.

[@stevennirk5503]

Can you ude your brushcutter immediately after replacing a piston?

[@dalriada842]

I'm trying to get an old Ryobi PBC 3046YE working again. The cylinder has one long side, and a shorter side at the back, opposite the intake and exhaust ports. The piston slipped out before I had the chance to check the correct orientation. Do you know which way round it should go?

[@josefeliciano2938]

Gracias por explicar tan claro.Puerto Rico)

[@hoonyfan2924]

That was a nice tutorial. I was surprised you didn’t mic the cylinder wall and do a lite hone before installing the new piston. Is there a reason for not taking that measure?

[@chancewindham1718]

Because it's a weed eater and not a space shuttle.

[@WV591]

Why you don't sell those rings separate?

[@xx3868]

Question- I have a Stihl that i exactly the same crankcase you are showing here with 2 bearings facing each other in housing so you cant get behind them to knock them out. book says heat to 140C and tap on hard surface and they will fall out either end. I have done this and hit a bit harder than instructions and they are not budging due to old age stickyness likely. DONT want to risk cracking case with to much force so any way i can get those bearing out without damage as need to get at least one out to replace oil seal as having on and off idle lean issue when its hot and pressure test at 9 lbs didnt show leak. I figure its when crankshaft is turning or seals are getting hot then leaking slightly? so replacing the 2 gaskets and one oil seal too to be sure CC is air tight at any temp. Thanks

[@chadlasher1793]

What is the purpose of taking the muffler off? I have a Cub cadet cc2020, a very similar model, and able to take the Piston area apart with removing the muffler. But i will say that either that or something has caused the motor to refuse to start and feel stiff

[@kelvinbridglal4879]

Nice detailed removal and reassembly. Hope i can perform this one day. Great video. I would like to see this done on a Shindiawa C350 Trimmer. Thanks, watching from Trinidad.

[@georgeharris3436]

You have awesome videos! I have a question you may be able to help me with. I have a Ryobi SS30 that I can not get started. I have watched several of your videos cleaned the carb because I thought that was my problem because when I shot some started fluid in the carb I thought it was trying to start but it never did. I have checked the exhaust and the spark arrestor screen and they are fine. I have also checked for spark and I have good spark at the plug. The only thing I can think of is maybe the piston and cylinder head may need replacing? What are your thoughts on this issue. Also, do you know the factory settings for the high and low carb adjustments because a guy at work said that they needed adjusting when I first began having a problem with the machine so he adjusted them and now it will not even start....even with starter fluid in the carb. Any help would be greatly appreciated. Thank You

[@doctorboy5892]

Replace the piston and rings as in this video. If you have a 4 stroke no need to adjust carburetor.

[@wacio]

What is the reason you're removing the clutch and flywheel - it almost looks like unnecessary. Would it be possible to just remove carb, exhaust and than cylinder. Didnt see anything preventing to do repair without disassembly of the front side of the engine.

[@FIXTechGuides]

Thanks for the question. In some cases you may not need to remove the clutch and flywheel, but I think in this case we just found it easier to access the piston. Thanks for watching!

[@RANGUIDRY]

You can save the trouble of stuffing a rope into the cylinder by blocking the crank with a screw driver after removing the fuel line and tank assembly.

[@alexandersaucedosr7124]

Mark my weedearters won't start keeps spitfireing what do i do

[@jonathanjanek7101]

Why did you remove the flywheel?

[@jace_Henderson]

You can get the piston out without having to do anything with the clutch or flywheel. Unless my TroyBilt TB70SS is different from that ryobi.

[@jace_Henderson]

Juan horn I would but it’s working perfectly now and I don’t think my parents would enjoy me taking it apart yet again. But take the back cover and gas tank, carburetor and carburetor housing off and you should have a view of the crankcase where the piston rod can be slid out, just unscrew the cylinder head and do a little wiggling ti slide the piston rod out.

[@Unknown-kd3ri]

When you install the crankcase cove do you need to put some sort of oil

[@FIXTechGuides]

Hi, as long as you lube the new piston and rings before you install them into the cylinder, there will be no more lube needed. Once the engine starts the oil in the fuel will start lubing the new parts.

[@amilakr4075]

Thanks bro

[@johnwyman6331]

Are the replacement parts OEM Ryobi? If not what brand are they? I also noticed that rod looks stronger also.

I need help! When I attach the edger to my echo trimmer, the enter shaft starts to turn. I constantly have to stop and straighten it back. How do I fix this problem?

[@frankg6245]

Wouldn't that new ring just burn up cause the cylinder wasn't honed?

[@FIXTechGuides]

Depending on the condition of the cylinder. If you hone the cylinder too deeply you'll need to use oversize rings to keep your compression. Most of these manufacturers don't offer an oversize replacement.

[@frankg6245]

Honing a cylinder is to score the cylinder so the new rings can be broken in properly. Honing to much can cause out of round cylinder. So honing isn't ment to remove much metal. You won't lose much compression by honing. If you're removing metal to clean the cylinder you should really use a boring bar so you can keep the cylinder round. Measuring the cylinder will tell you if you can bore the cylinder without having to step up to the next available ring size. You can go up to .010 with a standard size ring. If you're over that then you will need to goto the next available size of .020 over. Most of time you can use a different manufacturer to get the right size of rings you are looking for as long as you have the right ring dimensions and measurements. Like if your compression ring is a Barrel Face ring and the second ring is a Wiper ring and the 3rd type of ring is the oil ring such as Steel-Vent ring Type 710 Spacer Type 716 Rail Type 825 OilInnerSpring. There is charts online that has the shapes of rings so you can figure out what combination fits your product.

[@doctorboy5892]

@@frankg6245You gave a good explanation of the difference between honing a cylinder and a cylinder rebore. Honing is just smoothing the walls so the piston rings don't rub and burn up like you said.

[@sanddollar9322]

hi,, what is the bore size of piston on a echo rsm 225???????

[@FIXTechGuides]

Hi, the diameter of the Echo SRM225 piston is 1.25.

ok thanks

[@FIXTechGuides]

Your very welcome.

[@johnwyman6331]

I find it interesting that the new piston had two rings and the original piston only had one. I wonder why?

[@FIXTechGuides]

Hi John, manufactures do have a tendency to upgrade or change parts of their tools. I would think that this is one of them.

It sounds like you have done it all on your engine. We do have a video on How to Diagnose a Two Cycle Engine. I hope it will get you going again. Here is the link: kzbin.info/www/bejne/nnmqhIuor76NkLM How to Diagnose Two-Cycle/Two-Stroke Engines www.youtube.com Mark is here to walk you through the steps needed when diagnosing your two-cycle engine issues. These steps will be the same for all the two-cycle tools in your lawn ...

My trimmer engine has good compression , measured 90 psi, I have the spark tester and look good, my carburator is brand new. The engine doesn't start , The flywheel is in the position with the wooddrof key, I can't see what other reason for don't start , the fuel is clean. That is get it me crazy.

Pointless to change piston without new bore or honing it out.repair will be short lived

This Ryobi engine has a hard chromed bore. you need a diamond hone to do this, The cast iron rings have a specific finish on the face that facilitates ring break in to the chromed bore.

[@doctorboy5892]
