All engines are decent until they get damaged.
It happens a lot more than people think.

Not that hard to rebuild my guys do it a lot as stumps and items seem to hit the underside of mowers.

I got an old European diesel Honda not for US markets that I pulled out of an old Belarus tractor from the 80’s and put it in a riding mower frame. I had to make a muffler to keep the diesel exhaust away from the operator. It was just a fun project for the guys in the shop and we use it to cut grass around the shop.

Honda’s are typically a better air cooled engine as it is an OHC versus OHV. OHC usually Tighter tolerances.

Frames rust due to grass is very acidic.
Old days they were primed and painted.
Now they are dipped and power coated.
Slows down but does not stop the rusting process.

Some mfg make a coating similar to pam cooking spray. The coating keeps the grass from sticking which is similar to a good deck spray.

Do me a favor and post updates here on the job. I did the same thing to mine, and want to fix it.
Where did you get the parts from?

Funny thing here is that the industrial-rated version of this engine, GXV160, is OHV and not OHC like the two lighter duty GC and GS versions.

I plan on doing a few updates once the part comes in, ordered the part online from Jacks Small Engines. This HRR216 model lawnmower has the N3 type PTO shaft, yours might need another version but the cranks all cost the same it seems.

Cleaning so frequently is probably why the deck is rusting out, giving the abrasion of use a shot at bare steel every time you mow.


I only use one of those little straight stream power nozzles to blow off the grass with my water hose. I have never used anything to scrape or brush off the clippings.

I may have to look into one of those Honda's to check out that Nexite deck. Never heard of it until your post. Appreciate the heads up.

ETA: I checked out that mower and it's over $600 for a bare bones 21" cut. Out of my price range for that mower.

We had close to the same one, it took as long to get it running as it did to mow (every time).

I went and bought and old Briggs and Stratton at a pawn shop for $50.00, that sucker has cranked on the 2 or 3 pull every time for 11 years.

The holes in the deck are now covered in sheetmetal and pop riveted to the deck to keep grass from flying up in my face when cutting grass.

Anybody reading your thread title would think you implied the Honda engine somehow failed early in its lifespan, that's the only reason I clicked on the thread,



I thought the dense ones hung out in the OT and PB.





Just give up and admit the title is misleading. Good luck with the repair, though. Not really sure how involved that is, it's been quite a while since I've even owned a lawn mower.

It's not that much, other than the puller it's a job needing only basic hand tools. These are very simple little engines.

Apparently the sudden stop bent the crank PTO area AND caused the flywheel to bind on the woodruff key on the mag side. Found that out the hard way though:





Little work with a grinder and cutoff wheel:


Rest went as it should. Can basically have these engines apart in 30 minutes or so.



Yup, pretty good bend in that. They must make the PTO area pretty soft because there was nothing to suggest that the aluminum of the case areas that support the crank are damaged.



Little scuffing on the journal but nothing that wouldn't be out of the ordinary, same with the big end of the rod and the cylinder bore was spotless.



Interesting how these things can live with only splash lubrication and steel-on-machined-aluminum surfaces, there's only one thrust washer on the PTO side.

Parts came in Wednesday and finally got around to putting everything back together, took less than an hour and the mower fired up on the first pull and ran just fine. My yard had about a good month of growth too, zero issues just like a good Honda lawnmower should... You can basically rebuild this engine without taking off the carburetor or muffler, just need to loosen the carb enough to free the governor linkage. Mostly nothing but 10mm bolts and a 9mm wrench for one of the studs holding the coil.
