Fuel System

The fuel tank for the Muscateer mounts under the front of the body.  Two carriage bolts held the fuel tank centrally located between the headlights.The filler cap sits front left.


A 4 gallon "BoaTank" with a float style gauge/cap assembly was used.  We looked on the web for information on the Manufacturer, Bettcher Manufacturing of Cleveland Ohio, but found little on this type of fuel tank and gauge.


Our gauge is a bit worse for wear, unfortunately the glass cover is broken.


A rubber pad held the tank tight against the fiberglass shell to avoid rattling.  And the float unit is very corroded and in marginal condition.  Hopefully some Evaporust can clean it up well enough to reuse.


The tank mounted to the body with two carriage bolts and a piece of plumbing pipe strap.  Industrial, but effective.




The fuel line ran down the right side of the hull, pop-riveted into place with small plastic clips to retain the fuel hose in place.  Oddly, some pop-rivets were steel, some aluminum.  Possibly past owner repairs.



Ramming Speed....!!!!

A quick look at the propeller and rudder and their associated components.

Drive Levers

The drive levers, one for engaging the pulleys to power the prop, and once for rudder control, were one of the few items that were fairly corroded.

Failed to get a good shot of the controls, pre-disassembly. 





Cable Controls; Drive and Direction

The propeller belt drive free wheels when not in use.  The long cable at the top of the photo below cams the drive pulleys to engage the drive. 

The shorter cable to the right provides rudder control.  As noted we are unsure how much steering a playing card sized rudder will really provide!


Propeller Mount, Shaft and Assembly


The propeller shaft mounts in a plate secured to the rear fiberglass.  All component were (surprisingly) easily disassembled. 

Propeller component, left to right; input pulley, driveshaft, shaft bore/seal plate, propeller bushing, propeller.


A closer look at the input end of the assembly.



And the place where the power meets the puddle!


With only one small O-ring in the assembly and no soft seals it appears that the grease nipple and filling the shaft tube with grease provides most of the watertight seals along the shaft.




Rudder Assembly

The rudder mounts to a plate and shaft with two nylon bushings. 

The rudder shaft presses through the two bushes, and was extremely tight.  So tight that the rudder could not be operated by hand.  It took putting the assembly in a vise and some significant force to rotate the rudder and shaft.  Some PB Blaster and gentle "persuasion" got the assembly apart.





In the reassembly this will have to be looked at and possibly modified to allow easier rotation of the rudder int he shaft housing.

The "Black Box"

As removed, the unit has no visible markings or numbers.  It is quite "industrial" in its manufacture, as the plate steel obviously made fabrication and assembly easier and lower cost than a cast housing.  Lotsa bolts holding it together!

A post on a forum noted that the Muscat Corporation used this type of transmission on "early" Muscateers.  Not sure how to define early vs. late, or even when this unit was built.  As #2146 one could assume it is actually the 2,146th one built.  Or maybe they started at #1,000 in year one, or 2,000 in year two, and the sequence of builds did not match the actual serial number.

Right hand front, control input shafts

Left hand front, control input shafts
The two joysticks lever the "input shafts" and when hand turning the clutch with the levers forward or back the drive outputs engage.  So the transmission spins freely, a good sign, but until we get a bit more time to test no telling if it is fully functional or not.

Left hand rear, secondary clutch (frozen)

The clutch retaining bolt came out quite easily, as have most of the bolted connections.  However the clutch will not come off the shaft, and there is are no taps or a central hub to get a puller on to remove the item.  It has been sprayed with PB Blaster and we'll let it sit for a while and see if the magic juice can help free the clutch from the shaft.

 The throttle cable is free and the control lever easily moves the cable in the sheath.

The disassembly continues...

In order to refurbish our Muscat Corporation Muscateer, dubbed "Britney", we decided to strip the hull/shell completely.  We fabricated a cart to roll it around on during the restoration.


The Black Box in-situ

This allowed the Black Box transmission to be hoisted out (it is heavy) and the shell rolled out from under the transmission.

Hoisting the "Black Box"

Once the transmission was hoisted, we rolled the shell out of the way, and lowered the Black Box onto two pieces of 1" pipe.  This allowed us to easily roll the box out of the way, and move the shell back into the small work shed we are using.

Now all that is left in the shell are the axle sprockets, two rear tensioners, the limited wiring, and the control cables for the propeller engage and rudder control.

Next step, finally stripping of wiring and other miscellaneous items to get down to the bare hull. 

Then its determining the plans for providing a new engine and tires....

A bit of historical data

In researching the Muscateer not much information could be found on the web. 

It appers these wer made in 1969 or 1970, no form prodcution numbers, options ro deatails could be found.

In the prior post the brochure from the 6x6 World website was noted.  The complete scanned brochure can be found here.

http://www.6x6world.com/forums/content/section/149-muscat-muscateer-amphibious-atv.html

If anyone has original service manuals or any other documentation on the Muscateer 6x6 ATV, or information on the Muscat Corporation of Forest Lake, MN copies or originals of these documents would be of interest.

As #2146 has the keyed ignition, it appears the unit was originally powered by the optional 10Hp Tecumseh HH100 engine.  It is, as noted, missing.  Mount area shown below.


As with the Muscateer, if anyone has information on the Tecumseh HH100 engine, it would be of interest.

As previously noted, #2146 also was provided the propeller option.  A lever drive cams a belt to power the massive 5 1/2" diameter prop!   Hope we don't lose too many hats!

Massive power!

Cam pulley for belt drive to propeller.

Rudder and cam control cables.

Upon initial inspection of the existing drive system...

All the Muscateer's drive chains and sprockets are in place and in reasonable condition.  Some light rust but most were still flexible.


 



We are hoping some Evaporust will clean up the drive chains well enough to reuse the existing ones.

A quick look inside the Muscat Corporation "Black Box" transmission left a good feeling, as it all appeared to be pretty clean, and hand turning the driveshafts led to rotary motion.  While not conclusive, a good sign the box may be in running condition.





All the lever inputs move smoothly, and the internal clutch plates seem to move side-to-side to provide friction for drive.  Unsure of the specifics to do an true testing/adjustment, that will come late, but for now it looks to be in pretty good shape for a 40+ year old abandoned item!

Initial clean up...

A bit of pressure washing to remove dirt, leaves, spiders, and other associated items collected in who knows how long while it sat in the woods.



And then a first look at the overall condition.  The wiring, transmission (affectionately named "the Black Box" by Muscat Corporation for obvious reasons), controls and axles all seemed in decent shape.




Note keyed start, "top-of-the-line" electronic ignition option!  Not bad for 1969/70!

(OK, the tires ain't so good....)


And a big bonus, the optional propeller drive for amphibious assaults!  As Ned noted, "The playing card sized rudder will allow serious maneuverability"! ;-)




More research to follow.....
