Honda HS621 restoration
Original Message   Oct 27, 2013 8:57 pm
Well here is my most recent find.  Actually I bought it at an auction back in August.
But didn't get around to restoring it until earlier this month.
It was pretty rough but started on the second pull. So figured it
was worth the 40.00 I paid for it.


   

The upper handle was pretty messed up.  So I replaced it with one that I kept around from and old Toro CCR2000.
It bolted right up and was also a little longer than the stock Honda handle.  Which is nice.





Stripped and repainted the muffler cover.  As well as the lower handles.


 

The blower housing sides needed quite a bit of straighting.  Also welded on a small piece of steel onto the bottom of the left  side
where it had been worn off.  Not adding the piece would have allowed snow and water to get inside what is the belt and pulley
compartment.  That would not be good.  Installed a new set of paddles and a new scraper that I bought on ebay for $53.00

 


Cleaned up everything inside.  Have to say that these blower are really well built.  The steel used for the bucket and the
undercarriage is heavy gauge.  Actually the undercarriage is plate steel.  The bracket between the engine and the bucket
is like something you would find in a automobile.

 

Sandblasted the bucket and sealed some of the joints with auto Spot putty.  Gave it two coats of Rustoleum Red oxide primer.
Then two top coats of Krylon Tough Rust semi gloss.  I did end up giving the center interior section of the housing another
coat of black Rustoleum Hammer finish.  That gave it a smoother, slicker finish and that paint if extremely durable.
That is also what I painted the auger with.

 



 

Didn't do much else other than check the carb bowl for dirt or signs of water. 
Replaced the plug, oil was good and clean.  Belt was good.  So it's ready to go.

In case some of you noticed there is a modification that I made.  I designed a chute rotator system for it.
Which I will show in another thread.

jrtrebor, very nice find! especially at that price. How do you do it? Are you known as the snow blower guy in your area so everyone tells you about the deals. I'm jealous.
A great refurb also. I have the same questions as aa335 about how you treated the plastic cowl and added the rotator.

Thanks very much.
I watch a lot of online auctions the the area.  Every once in a while I get lucky.
Seems that people sometimes tend to shy away from blowers that look really beat.
I think in this case the price of Honda parts may have also played an part.
But as aa335 said, the engine alone was worth more that what I had to pay.
So I was thrilled to win the bid.

That plastic or vinyl is strange stuff to work with.  I'd really like to know what type of material it is.


I would guess it's polypropylene or a variant of Delrin.  Most likely polypropylene, essentially the same material as on milk jugs.  Pretty tough material for plastic housings.

Talent is only used 1% of the time, the rest is sweat, banging, and swearing.

@jrtrebor, Have you had a chance to try out the Honda HS621? What did you think? Did it meet you expectation? The OEM rubber parts for HS520 are fairly cheap (1/2 price of OEM rubber peddles for HS621). Did you go with the OEM rubber peddles? Please tell us about your new toy.

Swearing is what I did when my HS621 did not blow snow. It is clogged constantly. The paddles, scraper are all new. Bought a new belt last year too. I have had to shovel instead since then. The new belt was not Honda OEM, so this week I got Honda belt. My question: How to install the belt so as not to cause constant clogging? Do I need to put it inside out?

Your belt tensioner may be out of adjustments. Not all power from the engine is being transferred. You will have to adjust the tensioner to maximize the power transfer. Try some youtube search. AA335 is an expert at this.
