Honda Harmony 215 Transmission Fix

The Honda Harmony 215 Transmission Tutorial

I have the solution to your Honda Harmony 215 transmission problem. If the transmission is slipping, skipping or it feels like it's popping out of gear, I can help you fix that. If your wheels spin while you suspend the rear wheel off the ground, but stop spinning once they hit the ground, I can show you how to fix that too. I believe this is the best information you can find on these problems, I have spent weeks trying to figure this out, and now that I have found the culprit, I have laid it out for you in a simple and easy an to understand format with video, pictures and captions.

Remo 4 years ago

Hello, thank you for such an incredibly good, detailed and informative video.

I have the same problem with my Honda (it's called HRB536 here in Europe), so I will try this out tomorrow.

Just want to ask, do you recommend opening the transmission to replace the grease even if the problem seems to be the lever? Is it worth the extra work, or is it risky, considering I have to put all the parts inside together again?


eddiecarrara profile image

eddiecarrara 4 years ago from New Hampshire Author

Hi Remo,

I don't think you need to if you have grease, if you have a hydro-static tranny, I recommend replacing the fluid.

There are more videos and articles about this problem that I have written, I even made a video on how to remove the transmission. The links to these articles and videos are right above the comment box on this page. I had another guy ( Paul ) who had a problem with his transmission, and with my help he was able to remove it and make a video about it, so I put that in my article as well, his problem was slightly different, so I wanted to share his problem and get as much info out there as possible because there are so many different models. If you attempt to fix your Honda mower, video your repair and I can use it in my article as well (If you want).

If you need any help, let me know, and don't forget to check out the other videos and articles, take care for now Remo, thanks

Hi Eddie, been following your repair info on the Honda mower for a while...its been a great help but I have a question. I am currently restoring a HRB215K3 SXA and have a problem with a seized input/pinion shaft bearing and the bearing and pinion shaft. I checked on Honda's website a it looks like there are no internal parts available for the 2 speed trany. I have the necessary tools to press out the bearing but again the pinion shaft, having some excessive wear , on the bearing surface is not available as a part. The rest of the transmission is mint so I am hoping to repair rather than replace the entire transmission. Any advice would be helpful, thanks again! -Frank

Hi Frank,

Thanks for the feedback, it's much appreciated :) Is there any way for you to take a few snap shots and put them on Picasa, or even better, make a short video and put it on YouTube so I can see exactly what you are referring too?? I understand the shaft is worn where the bearing rides, but I would like a visual. Let me know if that's possible, if not maybe we can figure something out, thanks Frank.

JustinGasal 3 years ago

Nice information, Eddie. Doesn't quite solve my problem, though. I have a HRB215SXA Honda Harmony II with self-propel drive, looks identical to yours. My problem is that the belt keeps slipping off the pulley on the transmission, as soon as I engage the clutch. The belt tensioning spring fell off, and I replaced it with one from the hardware store. That's most likely the problem, but I didn't want to pay $30 for the Honda spring. I don't get why the tensioner pulls the pulley out of alignment anyway...seems like a stupid design. Any ideas on what else might be the problem? Thanks.

Justin


eddiecarrara profile image

eddiecarrara 3 years ago from New Hampshire Author

Hey Justin,

I'm not absolutely certain what's causing the problem, but if the self propel worked before the spring let go, I would say most likely that's your problem. I know that spring is super heavy duty, so if you do replace it with one from the hardware store, make sure it's comparable. Let me know what happens, it will benefit all the readers who have similar problems, and I would rally appreciate it, thanks Justin.

Have a Honda Harmony 215K2SXA two speed lawnmower. "Clunk" sound and I no longer have self-propelled. Bought a "new" transmission off of eBay and had it installed. They installed it incorrectly and I had only one speed. Took it back and then they said that it would not self-propel at all. They gave me my money back, but I now have a lawnmower without self-propel. Would like to fix it by either fixing one or both of the transmissions or put the two together to get one good transmission.

Any suggestions?

Thanks.


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

Hi Bob, do you know what the clunk noise was? Does the mower do anything at all?


BobAZ 2 years ago

After the "clunk", it was hard to push the mower – like it was stuck in gear. But that transmission was the original and is now in the box that the other one came in.

The "new" transmission will "sometimes", but not very often, will go into gear but not for long. I don't know what happened to it as it worked in one gear only when I took it back to the dealer. Then they informed me that it would not work at all. Honda would not honor my 6 month warranty as I did not purchase it from an authorized dealer – the box had a card on it that Honda said was from South Tulsa Mowers but they went out of business in 2011 – the guy on eBay was sell their stock for someone else.


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

Hey Bob, the only way to figure out what is wrong with it is to take it apart yourself or bring it to a reputable small engine repair shop. I don't know of anything common that would cause that condition except a broken or disconnected cable. Let me know what you find Bob, and sorry I can't help you out any more that I have.


BobAZ 2 years ago

Eddie,

I opened up my original transmission and found that the gear that attaches to the vertical rod (which the pulley goes on) has broken into three pieces. I am hoping that when I go back to my McLane front throwing mower – after the rye dies – I can remove the transmission that is currently in the Honda and take the top part of that transmission and put it with the bottom of my original transmission.

The transmission that is in there now worked when it was first installed, but they installed the cables incorrectly and it had only one speed – didn't matter whether it was in 1 or 2, it was the same.

When they went back in to "fix" now it only works intermittently, so I am using it as a push mower.

When I go to clean the grease off, is there a solvent better than gasoline that I can use? If so, what?

What is the grease I should use when "re-packing" the transmission and how much?

Thanks.


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

Hi Bob,

I recommend wiping out as much grease as possible with regular paper towels and clean the rest with brake clean (you can buy it at most auto parts stores) Then I would use a medium weight wheel bearing grease, and only use about a 1/2 cup or so, try to measure what you take out because I don't believe any has leaked out. Let me know if this helps Bob, thanks.


Phil 2 years ago

I had the same problem. I noticed that there was an adjustment of the cable at the lever on the handle. By adjusting it I was able to tighten the cable and get the wheels engaging properly. At some time in the future I will most likely need to do the shim repair


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

Hi Phil,

Yes, I had made a few adjustments over the years, but after a while, adjusting the cable was no longer working, that's when I figured out what was happening. Thanks for the feed Phil.


Jay 2 years ago

Great article. You state after removing the belt the spring is easy to remove. Really? I've removed the belt but still can't get the spring removed. Any ideas?


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

Hi Jay,

I'm not sure what your spring looks like, but on my model, once the drive belt was removed, removing the spring was easy. Try using a pair of cutting pliers to grab the spring, don't worry, the spring is harden steel and will not break. Let me know if his helps, thanks.


BobAZ 2 years ago

After putting in a new transmission, I get both speed while holding the back wheels off the ground. But when I let the wheels down onto the ground, it will not move forward. The wheels are not driven with enough force to move the mower. I have adjusted the drive cable from one end to the other and it makes no differecnce. What could be going on?


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

Hi Bob. Are there one way drive gears at the axle where you bolt the wheel on?Check those gears, they could be on backwards. Let me know if this helps, thanks.


BobAZ 2 years ago

They are correct. If I hold the rear wheels off the ground, they move in the correct direction – to drive the mower forward. But when I lower the rear wheels to the ground, the mower does not move forward. The wheels are not being driven with enough force to overcome the weight of the mower. If I pull the mower backwards, the wheels "click" as they should. And if I push the mower forward, there is more resistance as I am turning the drive shaft. I cannot figure out why the drive shaft is not driven with more force.


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

Hi Bob,

That was the problem with mine. My shift levers were not allowing the transmission to shift into gear completely, causing a ratcheting sound. If I were to push the shift lever all the way forward and hold it, the mower would move. If I held the back wheels off the ground the wheels would spin, but as soon as they touched the ground, they would stop. How do your shift levers look ?


BobAZ 2 years ago

I am thinking that it could be the drive belt. I purchased the lawnmower in 1998, and it is the original belt. Have you replaced the belt? If so, what do I need to do at the other end from the transmission? I'm guessing that I need to take the blade off, but what else?


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

Hi Bob,

You will need to release the spring pressure from the transmission. Check out the link to my other video on "how to remove the transmission" above the comment box on this page.


BobAZ 2 years ago

Eddie,

I have seen that video. I know how to remove the transmission –I've done that several times.

My question is regarding replacing the belt. I know how to get it off of the pulley at the transmission.

My question is what do I have to do to remove it from the OTHER end – the motor end of the belt?

Do I have to remove anything besides the blade or maybe not ever the blade?


eddiecarrara profile image

eddiecarrara 2 years ago from New Hampshire Author

It would be easier to get it off by removing the blade, but it's not necessary. You can sneak it around the blade, but the blade is only two bolts, plus you can sharpen the blade while you have it off, killing 2 birds with one stone :)


BobAZ 2 years ago

Have you ever removed the belt on a Harmony 215HRB?

Removing the blade does NOT let you take the belt off. Something else has to come off and that is what I asked.


Stan 17 months ago

Need help in HRT216 transmission pulley assembly. My honda mower does

not have the power to drive the wheels. The pulley seems to slip so the wheel do not drive forward.and sure it has a drift key and a bushing in the assembly. Please help---Replay needed. Thank you Stan

eddiecarrara 17 months ago from New Hampshire Author

Hi Stan,

Have you checked the cable adjustments, and the shift levers on the transmission for wear?


plg 13 months ago

My honda HRT215 began smoking from the belt. I took the belt off and looked around all all looked fine. One thing I did notice is that the transmission pulley in the rear of the mower does not turn when I try to rotate it. Is it supposed to rotate? What could be causing the belt to smoke? Did my transmission freeze up? Mower never had any transmission issues like slipping or grinding until last weekend when the belt began smoking even for only a few seconds when I stopped the mower immediately.


eddiecarrara profile image

eddiecarrara 13 months ago from New Hampshire Author

Hi Plg,

When you turn the pulley on the transmission the wheels should move, if the wheels are not moving and there is a lot of drag, maybe something is wrapped around the axle or maybe a wheel bearing is freezing up? I doubt it's inside the transmission, so it's most likely an external problem.


plg 13 months ago

The Pulley is frozen. I Cant move the pulley it backwards or forwards. The wheels move freely forwards and backwards and nothing seems to be impeding their movement. when one wheel moves forward the other goes backwards as expected and vice versa. The axle is clear of debris and clean. I will try and move the axle itself with a vice grip to see if that will make it move but I am stumped?


plg 13 months ago

Ok, I was mistaken, the axle moves freely when the wheels move. Now when I set the lever to engage the transmission the pylley is frozen and wheels dont move. I have been able to work the pullet and more it around but it is still extremely tight and diffilut to move. As I have worked it it now moves alittle more but feels tight still. Is there a way to free it up to move more freely or is it supposed to feel tight? Or Is it supposed to move loosely?

The pulley should move freely when the belt is disengaged.

honda harmony 2 months ago

My problem is when I lift back wheels they turn but when lowered to ground they stop. I pulled trans and looked inside and as you indicated looks fine. replaced belt and created shim for clutch. Only thing left would be drive pulley but can not budge bolt on engine and afraid if I torque to much it will twist off. Any ideas there? I am not thinking it is pulley because before I pulled trans I viewed mower running and saw that when mower was lowered to ground wheels stopped transmission pulley was spinning but wheels not turning and axel not turning??? Thoughts

eddiecarrara 2 months ago from New Hampshire Author

Thanks Mechanicsguy, sorry I didn't see your post earlier.

Hey Honda Harmony guy,

I don't think it's the pulley either. Have you already checked the drift key on the axles?


honda harmony 2 months ago

Yes, I just watched some additional repair clinic videos to verify and will check again, I watch your video numerous times. Left side should click turning clockwise and it does. I am not sure what to check next.


eddiecarrara profile image

eddiecarrara 2 months ago from New Hampshire Author

All your cable adjustments for the shift lever and clutch.


honda harmony 2 months ago

I reviewed the adjustments and will try soon. If this doesn't work I am at a loss. The last thing to replace would be the drive pulley assembly. I don't mind replacing but I tried to remove bolt and it will not move. I sprayed with two different kinds of lubricants. Still no go... I am afraid if I apply to much leverage it will twist off. Any Ideas?

eddiecarrara 2 months ago from New Hampshire Author

Try a small pipe fitting torch using map gas, heat will usually do the trick, just clean the oil first, and be careful of spilling fuel.


honda harmony 8 weeks ago

I did try this but maybe didn't get hot enough I am assuming right to tighten left to loosen.

Yes, that is correct, if the bolt or nut was a reverse thread, usually it is marked with an arrow.
