So, for those in the power equipment repair trade. How many of these cams have you replaced? Think I’ve done a dozen or so but I’ve honestly lost count at this point.
Honda HRX217K6 camshaft failure

Nobody else fixing these?
170 is having the same problem although it doesn’t seem to be as bad as the 200. Decompression mechanism is sticking causing hard starting. Honda is replacing the cam under warranty.
That’s correct, Honda is getting out of the lawnmower game. They really dropped the ball with this new GC engine. Went from OHC to pushrod design which makes no sense to me. Don’t know the number of affected units yet but I’d bet it’s in the thousands.
Yep. Stop sale was implemented about two weeks ago. We’ve been fixing them under warranty for some time now. Don’t have any further info beyond that.
I have the same mower as pictured. It's about 4 years old and have had zero issues. My son even uses it to mow 6-10 lawns a week besides ours.
Is just the newer ones failing?
It's a sad day when Honda has reliability issues with their small engines as for years they where bullet proof.

Started seeing camshaft failures this year. If I had to take a guess I’d say these mowers were manufactured in the last 12 to 18 months.
its not really hondas fault, the vender who made this part did not make it according to procedure honda said it should it be, as the first versions of hrx with 200cc engine seem to be fine-
every manufacture seems to have problems with plastic injection mode suppliers- they seem to never let the parts cool correctly is biggest issue from past plastic part problems from toro husky etc

Your good, this only applies to the K6 manufactured in the last year or so.
Briggs eng on Brute mowers are blowing through plastic cam shafts also. why in the xyz world wood a mfg use a plastic cam shaft ( besides the obvious part cost factor) use for a season or 2 and then it becomes a $300 throw away item. not right in my book. somewhere along the line with car engs i heard/read of carbon fiber reinfoced connecting rods ( ya that not working to well either)
So, I may have been incorrect earlier when I said your mower isn’t affected. If you can give me the serial number off your unit I can look up date of manufacture.

For those of us who are curious, could you share a few photos of the failed cam?
It’s a manufacturing defect not really a failure. They’re not breaking so visually they look the same as the replacement part. I’ll get a few pictures tomorrow.
Plastic cams have never seemed like a great idea to me.
This is a defective cam I replaced recently. From what I’ve heard the parts were ejected from the mold too soon which caused them to become distorted. This results in the decompression mechanism sticking and thus, hard starting.

Wow, it is actually plastic with plastic lobes! That is something I haven't seen before.
Does it say what type of plastic? POM, PEI, Peek, nylon?
The text on the sheet metal part looks like textbook China.
I work with a lot of injection molding. I am surprised the parts passed dimensional inspection if there is a binding issue with the decompression shaft.
Apparently Briggs has been doing this for a while.
