  • My new-to-me Hustler project

    Greetings fellow forum-goers!

    I'm Travis, I'm 16 and live south of San Antonio, Texas. I've been following AATVs with interest for the last few years, ever since Nick O. introduced me to them through a game called Rigs of Rods. I even ended up modelling an Attex and putting it in the game. There's a thread for it somewhere on this forum.

    Fast forward to last week, Nick messaged me on Skype with a link to a craigslist ad, it was listed as an Argo, and his asking price was $500. But Nick and I quickly determined that it was in fact a Hustler. The seller said it ran when he bought it and that he disassembled it and began a restoration of sorts and finished the entire lower half, he believed it was complete, and from what I could tell in the pictures, that seemed to be the case. All it really seemed to need was tires, and of course whatever work the engine may need to get running again. The seller said it would need new tires, but Nick said if there weren't any holes all the way through the tires, tubes should make them usable. So I contacted the seller and after a few messages asking various questions, I offered $300 and he came back with $330, which I had no problem accepting. So I made the 3.5 hour drive with my parents to take a look at it.

    As usual pictures can only tell you so much, as it turns out it's not entirely there. But I ended up buying it. The biggest thing that's missing is the engine cover/rear seat. But the rest of what's missing seems to be small bits and pieces. It did come with a box of wiring, the fuel pump, headlight seals, one headlight bulb, an extra axle flange, and a few other small things. Mechanically everything seems to be in working order, the chains have very little rust, good tension and when you turn the axle there's little to no resistance. The passenger side drive chain is missing, but the seller gave me a small roll of chain to cut down and use. I also shifted the tranny a few times and moved the sticks around, everything was smooth as butter. Though the right stick moves farther forward than the left, I've traced that to the bolt that acts as its pivot point, the welds seem to have broken free. It also has what looks to be a nearly brand new drive belt. Also, as far as I can tell, someone replaced the axle pins with nuts and bolts, so I see that as a big plus. The condition of the body is fair, there's only three minor cracks on the lower tub, but the upper is where the problems exist. It has cracks all around it, though only four or five that I would consider major issues.

    The tires are also a point of interest, they're in worse condition than I hoped, but they don't appear to have any holes going all the way through. So I'm on the fence on whether to attempt to use them or not. My fear is that something like a stick or sharp rock could punch through the week-points on the tires and puncture my tubes.

    Now on to identifying what exactly I have, from the data plate on the engine I found that it's a Kohler 440 (exact model K4402AX). And the carb appears to be a Walbro WF17-043655, but the F and 0 are partially worn off. As far as condition of the engine, it has a broken spark plug boot, the fan belt and recoil are missing, and the exhaust manifold has a small crack where it looks like it broke completely and someone tried to repair it. Other than that it looks to be in pretty decent shape, and it still has compression. It also has the flex pipe for the exhaust, but the muffler is rusted out and filled with dirt and various critter nests, so I doubt it will be much use to me.

    As far as the machine itself goes, it doesn't have the plate that would usually be to the left of the driver, and I can't find any kind of identification on the chassis. But with the help of a couple threads here, Nick and I are pretty sure it's a 1976 900HK model.

    Here's a list of what I think I need, so far, along with some things I'd like to get done for cosmetics/future proofing:
    - Tires (maybe)
    - New wiring (maybe)
    - Headlight bulb/lexan light shields (maybe)
    - Various hardware/mounting equipment
    - Throttle/choke cables/choke lever
    - Fan belt
    - Recoil starter
    - Carb rebuilt kit
    - Fuel line
    - Spark plug boot
    - Air filter
    - Muffler
    - Rubber bushing for motor mount
    - Lots and lots of epoxy. Possibly sheet metal for bracing
    - Paint to go over epoxy, maybe bedliner for the tub. Debating spray bombing the rims
    - New handle grips
    - Floor boards

    If anyone has pointers on repairing cracks, getting anything else done, places to find deals on parts, or even things to add to my list of things to buy, that would be greatly appreciated. After all, my reason for posting here wasn't only to share my excitement with the community, but also to get any advice I can. Because as a first time owner I need all I can get!

    Congratulations on picking up your Hustler. I wouldn't worry about the tires until you get everything running like you want. If they hold air at all, just use them while you test things out. If they don't hold air, tubes are just a temporary fix. With tubes, you would have to run higher pressure to keep the tires from spinning on the wheel which would shear a valve stem. You will want to avoid the tubes long term. Good luck with your rebuild.

      Thanks, Mike! I'll be sure to keep that in mind.

      Right now I'm trying to track down a rebuild kit for my carb. I've found a few different gasket sets, but only one true rebuild kit, and that's at Richard's Relics. I've been having trouble getting in touch with him though. I've also found my fan belt and spark plug boots, so it's looking like the only thing I need to find is the rebuild kit, then I can get everything ordered and see if I can't get this engine running.

        I'm sure Richard's Relics would have what you are looking for. Some people feel like he is overpriced so you may want to check eBay or even somewhere like Jacks Small Engine to compare prices. You could also go to your local small engine repair shop. They may also be able to help you out. Good luck with the engine.

          Change of plans, I'm ditching the 440 in favor of a 4 stroke. Both for better trail performance and to save the money I'd spend on parts to get the 440 running. But after looking at the price of a comet 780 clutch, I just can't spend that much.

          So what I'm wondering is, can I take my current clutch, and replace the springs with a 780 spring kit? It's either that, or I'd have to find an alternative CVT to use.

            Hey Travis, congratulations on the buy. You'll enjoy it when you get it going. For a trail machine a 4 stroke is the way to go, more low end torque a lot less noise. When it comes time to buy tires you can go as big as a 25 with minimal spacing on the rear axles. Good luck bringing it back to life.

              Thanks, yeah, I figured since I don't have anywhere/anyone to race down here a trail machine would be the most useful to me. Thanks for the info on the tires too, I was under the impression that only bigfoots could run 25s.

                Sorry to double post, but I really need to know about the clutch. If there's no way for me to avoid buying the 780 my project will definitely have to go on hold until I get a job of my own, which could be anywhere from next summer to a couple years depending on how things play out.

                So if someone who's done a 4-stroke swap could give some insight, it would be greatly appreciated.

                  I'm not a CVT guy but I think you can use a lighter spring in your 2 stroke clutch. You may also have a tapered shaft on your clutch but you can purchase an adapter to allow you to run it on a 4 stroke. If someone else doesn't chime in, give Roy at Quality Drive a call. He will know what you need to do.

                    the cvt is a different animal, you can take it apart and re-clock it, their are different holes where you can move the spring to get differnt tensions, i never could
                    get one to work for me on GOLIATH but you might. i could get it to haul a$$ but would not down shift properly so i ditched the cvt for a 780.

                    good luck

                      Thanks a lot for the info. Now that I have a starting point I can do some more research and hopefully make some progress on this.

                        I may be wrong but I think both Mike and WFO are talking about 2 different clutches in the last 2 posts.

                        The driven or transmission clutch (Convertor) could be out fitted with a green or red spring for 4 stroke use and although the ramping is slightly different it shouldn't matter for now. The drive clutch on the engine has a 30mm tapered bore and would be set at a different rpm engagement point than a 4stroke clutch, springs may be needed to change that ( though I am no clutch guy) and need the bore adapter Mike mentioned. I believe he meant CVT in general and not the brand.

                        The CVT brand WFO mentioned is a later piece than you would have and is seen on some larger Max and most Argo machines and is a less peppy (casual engagement) clutch set up.

                          No, you are right. Your post definitely helped to clarify things.

                            Wow, thanks Jim! That really makes this process straight-forward from here. Now I just have to see if my engine sells on CL.

                              Progress!

                              The past couple weeks have been great in many ways, including some relevant to this site.

                              With the help of money from my birthday and a small loan from my generous older brother, I was able to order all of the basic necessities to get my machine going. I bought a clutch from blink115 on this forum, and ordered a throttle cable, then picked up my fluids, nuts and bolts to get the upper on (which I somehow got too few of ), along with other odds and ends. Oh yeah... and a 440cc Honda Clone lol.

                              So yesterday my dad and I started prepping for heart surgery, we threw my 4 good tires on, got the machine off the trailer it was sitting on and drug it to the slab we park on. I have to say, I've never been so satisfied to see something getting towed. To think of how long this machine had been without its own tires to stand on, let alone roll, is really something.

                              Fast forward to today, I goofed up by cutting my right side drive chain too short, but was able to salvage it with an extra master link, then we cut off the old bolts for the engine mount, and the redneck cooler-rack that occupied the rear seat brace, then threw the clutch on the engine and did a dry fit, everything lined up really well, and will be perfect when we get a permanent engine mount. Now all that's left should be throwing my left side drive chain on, getting a mounting plate for the engine fabbed up, changing my tranny fluid and filling the engine with oil, then getting lugs on the center tires. After that it's shakedown time!
