Hi,

The drive belt on my Honda 2013 SA shredded at some point then broke. I have removed the remains of the old belt and I have a copy of the service guide instructions for replacing the belt but (and this is the big but) the transmission pulley seem to have been split into two halfs along the perimeter in the root where the belt seats. (To clarify, I'm talking about the pulley becoming two disks, both on the transmission shaft, one spins freely, the other is locked in place by the woodruff key). My question is, how does the pulley come off? Do I have to drop the transmission? A copy of the relevant pages of the shop manual would be much appreciated!

Best,

David

Hello and welcome, David:

The shop manual isn't very clear what might be required to just remove the input pulley on the transmission. Not sure if there is enough clearance to lift it off the input shaft and slide out. You may need to unbolt and slightly lower the transmission itself to get enough space for this job. There is an access panel on the topside for belt removal/replacement that might help with getting the pulley out.

I can tell you the input pulley is a one-piece part, so sounds for sure that yours is damaged. Honda still offers a new pulley, Honda Part Number 76215-771-010 but it is a bit spendy at $133.88 list. Google the part number to find a Honda Dealer selling it online, or use this link to find a Honda Dealer in your area:

A new genuine Honda drive belt is part number 22431-771-003 / $44.88.

Hope this helps.

Thank you Robert! Before I splash out for a new pulley and belt, can you (or anyone else) confirm that the transmission can be checked by simply putting the shift in gear (out of neutral) and spinning one of the wheels (lifting the body so the wheels clear the ground) and checking that the transmission power shaft turns? I assume it should be smooth and noise free? Thanks again!

That sounds reasonable. I'd try 1st gear as it should be the easier one manipulate.

Was the tractor driving/shifting okay before the pulley broke?

The seller told me that all it needed was the belt and that it ran fine until the belt broke. So I bought the tractor thinking it wouldn't be too hard to fix (I don't think he knew the pulley was broken). The motor runs nicely and the deck blades spin (I have already removed the deck in anticipation of replacing the belt). The belt both shredded and wrapped a wide piece of itself around the shaft with a long piece of kevlar or whatever) garroting the pulley! My worry is that the transmission is unavailable and was messed up during the failure of the belt. If that happens, I'll have to find a donor tractor or hitch a horse to it

Thanks again for your help!

Before you lash out putting good money after bad, it might be worth trying to bolt the 2 halves together. If for no other reason than to check the tranny is in fact working.
Mind you Hondas are worth spending money on.
The input pulley is spot welded together so if not damaged too bad you should be able to get a small clamp, or lock jaw pliers in there to hold the halves together while you drill a few bolt holes
I do not recommend mowing like this but it should hold together well enough to do some test drives

Thanks everyone for the comments.

The transmission seems to work based on the test described above (at least it did after I remembered to release the parking brake). Thanks for the bolt-together-the-two-halves of the pulley idea. I thought of that too but I will still need to access the pulley (and at this point the cost of the new part, if everything else works, is not a barrier). It looks to me like dropping the transmission is the best approach to pulling the pulley off since I may need to put a gear puller on it. Also, I guess there is a circlip ring on the top of the pulley but that's hard to access so, again, dropping the transmission seems inevitable. As far as I can see this will require removing the axle bolts (two on each side) plus the separating the shifter linkage somewhere. I might be able to do that without removing the wheels but maybe I should just to see what else is back there.
Thanks for the opportunity to think this through, any comments or alternative approaches, would be welcome!

Might want to invest in a factory shop manual; it can save you countless time and avoid much frustration when doing repair work. Honda sells them direct via eBay and Amazon, free shipping:

Most times you remove the body rather than dropping the tranny.
That way you do not alter any of the settings of the levers & controls.
Heed Roberts advice.
Honda manuals are well written and worth the few $$ they ask for them.

Update!

I ordered a new pulley and, after inspecting it, it turns out, that the transmission drive pulley is split, the two halves (top and bottom) of the sheave (or pulley) turn independently. Strange!

I did order the manual and it is nicely laid out but it does not refer anywhere to the transaxle pulley. The transaxle, yes but but not the pulley.

Removing the body sounds like a sensible approach -- thanks Bertsmobile1 for the idea.

It's weeks later but I just wanted to follow up on this (and share a lesson or two!) in case it helps someone in the future ...

I realized something was messed-up with the pulley on the transaxle and the pulley (an expensive part) could not be replaced without dropping the transaxle. So I proceeded to release the six bolts that hold the transaxle in place and, while jacking up the back of the tractor, I realized that something was amiss! The bracket that connects the frame to the transaxle had fatigued at the flange. One side was broken off and the other was cracked half way through! Clearly the "it just needs the broken drive belt replaced" line that the seller claimed should have been followed with the question "what could cause the belt to break?" Anyway, I managed to find a used bracket (it's the black sheet metal piece that wraps around the back of the frame) on ebay for a 2113 and fabricated an adaptor to make it fit my 2013. Clearly the failing bracket put unexpected loads on the transaxle pulley -- the woodruff key was mashed and the slot in the old pulley was mangled. After a good cleaning and replacement of all the messed-up parts including the brake pads, I reassembled the back side. Then I realized that the front wheel bushings were badly worn so I replaced those. Finally after everything was adjusted and working, I fired the engine up and proudly drove around the yard for a bit before returning to the garage to put the mower deck back on. That was when I realized that one of the mover spindle bearings was messed up. So I replaced the mower deck bearings (one of which was spinning in the housing) and we are ready (in four months or so) to mow the lawn.

Moral of the story: buyer beware. The thing runs great now so on to the next project ... does anyone know where I can find the Honda snowblower attachment for the Harmony 2013 tractor?

Cheers,

Foe.

I believe the RAD company in Canada made the SB2040 for Honda. Get the owner's manual here:

Enjoy your mower, for the next 20 years or more.
The only part I regularly replace on Honda ride ons are the steering pin bushes.
Not that they are a weak point as we are tallking 5 years or so.
It just sticks out in the mind because nothing else ever seems to go wrong with them
I have 1/2 dozen or so of the 4000 series in my service area that seem to have been sold off when the local Honda lawncare franchise changed hands.
They are all 20 years old and basically good as new,
Which proves that some mower customers actually have enough brains to work out the real value of a mower and not just react to the purchase price.
