I got a gx 35 surprise today

[Old Bob]

Push the pin (its labeled as axle in the exploded drawing from Honda) out the front.

The cam should drop down, then pull the belt to the front of the engine and pull the sprocket assembly upwards working the belt off as you go.

In the picture is looks like there is some damage to the front part of the hole, try to push the pin back and open the hole with a reamer.

thats nasty.

a honda shouldnt do that. methinks a careful double check on engine numbers etc might uncover a chinese clone.


a common saying regards honda...easy to say, hard to fix.

oh, they make great engines and they are relatively easy to work on, but parts are expensive, and in my experience...once a honda develops troubles, they wont ever go away.

you may find, with a full strip down, that something un-foreseen is bent, damaged, broken and the dollars quickly start adding up.

mind you, i only have a gx25 and im not about to tear it apart.

im with GG. buy a new one. keep what you have, fiddle with it, pull it down, try and fix it, keep it for spares, etc... use it as a learning aid now.

Not a bad idea, the only thing that could get damaged is the oil dipper, that is the only part in the sump.The oil system in the Honda is separated from the crankcase so the damage would be minimal.
look at the cases on the carb side, it should say Honda GX35 if its genuine Honda.
In all the years since the OHC was introduced I've never heard of a cam breaking.

i was at a concreting supply place and they had a sign up showing the larger gx200 etc, and a few of the "cloned" examples. warranty purposes and all that.

not just the fact that they say the engine number, but the whole way the numbers are written, and casting quality all combined together.

i havent had a good look at a 35, but something about the amount of flash on the cambeltcase seam there, doesnt ring honda to me.

i could be entirely wrong


i havent heard of cloned gx35s yet! the robin is cloned by huasheng

 

[Old Bob]

The M4 range only have Honda and GX35 cast in, no stamping like on larger engines.

More than one copier of the Honda M4 engines out there.
A company using the trade name Superior did clone several Honda M4 engines including the GX35.

The give away is the red shroud is not red red like Honda
but an orangish red.

Thanks Old Bob and HeadSmess

Never thought about a cloned engine

As you are more edumacated than I am about what and what isn't a genuine Honda.

Heads ? I will be taking another look at that flashing, Of course it could be my camera mount shakin around too ya know

The Cam looks good as far as I can tell, It's the gear that took a chit on me and busted out the rocker arm ( rocker arm being the one in front of the gear in the pic along with a big chunk of gear )

 

[Old Bob]

The cam and sprocket are molded together as a unit. you replace the whole thing, what you see in the front of
the sprocket is actually the compression release arm. The rocker arm looks to be intact.There is also a smal spring as
part of the compression release, it could be in the sump, I would definatly run a magnet through the sump if not
splitting the case to clean the entire sump.

Thank you for pulling my head out of the rafters and making me look at how to salvage what I have

bottom end was what I had in mind and taking care of business is what I am up too.

Magnets and all. Unfortunately, the gear is NOT made of metal, so a " case cracking " I do believe is inevitable

Thanks again for your insight

Any Update?

Thanks Sub but I like the motor the way it was out of the box. Except now LOL I think I will do a little tinkering. BTW the end results from the blow up a couple of weeks ago

I've had a very similar issue with my GX35 - see pic

How did you get on, did you manage to get yours repaired?

BTW mine is a genuine Honda unit fitted to a brush cutter bought from an authorised Honda dealer.

Pics are too small to see anything.
