Planning continues.

Looks like I can use two 6006-2rs bearings for the outboard CV hub/carrier. That will save $$ over a Honda specific bearing.

thinking about ditching the Argo bearings in the hull as well. Since the suspension is going to take the deflection (will be bracing up the Argo "go kart" frame), no need for anything other than a simple tapered roller bearing. Just need to find the proper size, then a seal and make a housing if needed. Easy stuff as long as I can find a bearing.

I'm also thinking of using the 2002 Bombardier quest front end components on the very most rear axle set.  I'm thinking of installing the axles, rotors, hubs and knuckles. This would allow me to mount the Quest brakes to the rear most axle and use it as my park brake. My 86 doesn't currently have one, except for a wood block I use to stuff down behind the levers. 

It also would allow me to use the steering tie rod as a fixed link and allow some toe adjustments. Now that I think of it that might also be an option for the other 6 positions too if I use the Honda knuckles there too. It sure would cut down a lot on the fabricating if I use the Honda 4x4 knuckles and just make A-Arms to mount them to the Argo....Hmmmm...more thought needed on that one, but seems to be an intriguing idea.

A simple master cylinder hooked up to a park brake lever and some hard line would do the rest for the rear axle brakes. I've got several automotive ratcheting style handles in my parts piles and that are easily re-purposed. 

I plan to use a high positive offset rim to minimize the overall added width to the whole rig, so the brake components will be inside the rim to help minimize snagging and hang up issues. I can bury lots of the suspension and other parts inside the offset rims as I don't have the traditional turning clearance concern with a skid steer. It just has to clear the vertical movement component.

I'm currently tossing around options for 12" rims. I want something aluminum (to reduce weight) and bead locks would be preferable. I can probably go without beadlocks I have too as air pressure doesn't need to be so low if the Argo is on a suspension. Opens up my tire choices as well since I don't have to worry about too hard a tire carcass. Since I'm making most of everything, I'm not limited to bolt pattern, so I've been looking outside the ATV world for 12" rims and tires. I don't really want to go any larger than 12" rims for weight concerns.

Looked at trailer wheels in 12". Prices are nice an affordable, but the widths available seem to be far to narrow for off road tires. a typical 12" trailer wheel seems to top out at about 4-4.5" width. Too bad really, i quite like the look of these:



Looked at golf cart rims, but they are priced nearly as crazily as ATV aluminum rims. They seem to have a high negative offset as well. Probably for that "deep dish" look old men and kids seem to like on their carts.

Tire options also reduce sharply for off road use above the typical ATV 12" size until you get into the truck sizes, typically 15" and above. That's just way too big and heavy for my little 8x8 Argo.

If I was a betting man, I'd say I'll probably end up with some version of a Honda 4x110 rim option...

Well, all sorted for axles and shocks. All honda TRX bits except for two bombardier quest axles/hubs, etc. they actually look like the same untis as the honda stuff. Same length, dimensions, etc.

Looks like I may be able to just use them all in stock form (ie: length).

I will have to machine off the inner stub on the inner tripod joint so i can weld on a flange to mount to a new/shortened  "argo" axle on the tub side.

That means I will need to fabricate the suspension body mounts, A arms and wheel bearing holders/spindles.

Well, the shortened axles for the argo side as well.....;)

Bah!

Went to pick up the grizzly parts (free stuff) and when i got there the guy said he changed his mind and wanted 200 bucks!

So I gave him some free advice about what he could do with those axles and left.

So i was sitting here mulling over the changes to my Argo in my head.


I was thinking about seating arrangements and then it hit me: why not move the fuel tank to the very rear of the compartment and do seating something like these:





I was also thinking of moving hte battery to the rear and using a bigger batt.

It's not a hunting rig, nor will it haul 1000lb of crap, so I don't need the cargo space. It's going to be a people/dog hauler at best.

Having the fuel and battery back there would help balance out the weight in the rig a bit better.

So, I've gotten a lot of parts super cheap lately.

Honda TRX500 stuff, Bombardier Quest complete front end (guy wrecked one and just sawsall's the front frame off) and some yamaha grizzy 660 front end stuff.

It's all in under 150 bucks (some if it was free, a "just get it out of the yard" type deal).

So I'm looking at pulling out all the CV axles and hubs. This will be my driveshafts and wheel mounts. The a arms I'll build, as I will the spindle/bearing carriers.

It will be a little bit of a "junkyard dog" with several different types of axles, but I'm ok with that for the price I'm getting them for.

And if it doesn't work out, I'm not out a lot of money.

Side bonus is they should be all parts that can be replaced with off the shelf stuff with fairly minimal modifications.

I'm considering leaving the axle shafts the stock lengths, although I will no doubt have to adjust some of them so they are all at least the same length as the others. It will make the whole rig pretty wide, but I'm not so upset at that thought. It's a lot of logging and fire roads around here. A wider rig is a more stable rig and that can't hurt if using it for SAR and hauling people and casualties around and it's still going to be much smaller than a 4x4 truck so it will be able to squirrel into a lot of small places. Maybe not the places a single quad can go, but again, I'm not too concerned abou that.

I'm going to go with 12" rims and 25" tires. Easy to find them in stores and I'm not concerned with the argo having to be higher to fit them. Making 4 of them fit on each side won't be  big problem, but I will have to kick out the wheelbase a bit. Not enough room between axle centers to fit 25's when it was built for 20/22's. Not a bit deal, I'll just offset the suspensions a bit from the axle centers. Probably shift the front wheel forward, the second set will stay centered, the third will be set back same amount as the front and the rear set back the most. Front and third will only have to shift (looks like) an inch or two, rear 2-4 inches maybe. Not a big deal since I'm going to be running CV shafts and no steering.

More ground clearance and I was already planning a retractable "boarding step" arrangement. Hard enough for me to drag my broken old arse into the argo as it is, needed a better way to get in anyways. Thinking the "steps" will be built into a rear cargo tray and walk from back to the front seats.

Front seats will have fold down rear backs to make stepping forward easier. The whole front seat arrangement is going to be fairly customized anyways. Idea in my head almost looks like the new "huntmaster" seats. Easy to plan for it from the beginning.

Tracks will require a little more thought. Getting the length is as simple as adding links. But now I'm thinking of building manual locking hubs for the middle set of wheels. Same idea as "track tuners", just built to fit my particular custom rig. That might be a bigger mountain to climb than I want and it's a long term plan at best.

Have "sort of" idea for roll over/racks. Found it on a gents web site. Aluminum and light enough not to add a lot of weight up high, has a built in ladder to climb it for better sighting and looks to be able to provide decent roll over protection for all the occupants. Mine will not be built exactly the same, but lots of good ideas there.

And every time I go out to the storage shed, I see my old VF750F interceptor that I haven't ridden in about 8 years (I have a couple other bikes) and can't stop myself from thinking about what it would take to get that "big old" V4 in to my old Argo!

sure; I'd loose the centrifugal clutch arrangement, but I would gain a regular handlebar clutch and multiple gear choices for use in both the Argo high and low.

And from waht I can find, the old Magnum 18 HP isn't a whole lot lighter than the VF750 lump. Around 50 lbs or so.

Hmmm.......100 mph Argo anyone?

Yipe!

;) 

Weight is going to be my biggest enemy here, especially if I want it to still be able to float....

Scored a couple trx500 front drive axles for super cheap. Even if they dont work, its something to start prototyping with for the suspension.

I put E,Track down both side's of my trailer. With those straps and tie down points it works with anything I want to put on it .

So i was thinking how it was going to look with the stantions for the rail on the outside of the farme.

Sucky, and possible snagging points.

Then it came to me: I'll put a piece of flatstock down the length of the trailer on each side.

That will give me a rub strip and tie down points the lentgh of the trailer.

Well, the heck with it.

I'm just going to get it over with. Chop the rail off and reweld it to the outside of the frame rails.

That will give me and additional 3" of useable deck width.

If that ends up not being enough for a springer, then so be it...
