George,

Is your caliper mounted sold to the chassis? I thought a caliper was supposed to have a little bit of “float” to it.

yes mechanicals are generally mountred with float or the rotor one. with these both pads are pushed out then pulled back by spring pressure to ensure zero drag. So you simply mount it solid and center the rotor in the middle.

Ok here is my clutch pedal. I drilled 5/8 holes thru the side of the running board and ran the pedal thru the running board thru the frame. I used a 5/8 i.d Bushing and with it slid on the pedal welded it to the bottom of the running board. This will support it and keep alot of the rattle previous mowers have had due to the sides of the running boards wallering out allowing the pedal to bounce.



Here is the brake pedal, I used an arm from an extra steering kit I had for the limkage mount. I slotted the running board so it sticks up thru it on the top side. Notice I don't have the center mount on this pedal. It doesnt recieve all the vibration the clutch pedal gets from the belt. So it isn't needed.



Here is both pedals mounted as you can see I got ahead of myself in work again instead of picture taking. I will get to everything you see here in up coming pictures.

Here is my rod mount for my clutch pedal. I make the arm then weld it to the 5/8 lock collar. I them slip it over the end of the pedal and uuse a bolt instead of the set screw to lock it down. I drill into the pedal and tap it so that I am screwing not only thru the collar but into the pedal also. Makes for a sure tight fit.


 Ok to mock up clutch linkage I use a sump pan and crank bolt the pan in place as though its the motor put the crank thru it then slip the motor pulley on. This allows me to put a belt on so that I can't get my clutch pedal in the right palce and make the linkage rod here you see everything in place I marked the rod where to cut. I then cut it and tap both ends for 3/8 right and left hand threads and screw the rods ends into it. All my rods are hollow 1/2 o.d. aluminum stock cut to size. I simply tap it for the 3/8 rods ends.


Here is the cluch assy completed rod in place. Next I will show you how I do the guides for the motor pulley.

There coming I am on dail up remember.....



Ok here is the placement of my front pulley guides. I hold it right up against the pulley without touching it. Tack the flanged nut in place. I do this to all three then remove the bolts and pulley and weld them on solid. This makes for a fast guide removale to change belts quickly if needed.



Here you see all three in place. Also you see a idler on the return side. This is more a guide to stop back lash when getting off the throttle at the end of the straights. it isn't tight against the belt you will see what i mean in up coming pics.




Here the belt is passing thru the idler. no pressure on it notice the depth of the belt. Now when the next three pics are up look at the depth with pressure on the belt.

Now notice with my finger slightly pushing on belt it sits deeper. So as you can see it is simply there to keep belt form whipping back and forth. The guide on this pulley is not as the others. I drilled a hole and tapped it for standard thread  and run a flanged nut on a 1/4 inch bolt screw it into the frame and the flange nut is the jam nut to keep it from backing out.



Here is the complete belt system done and everything in plce.



Here you see how I have added the clutch spring. This spring is the deck belt tension spring. I have a spacer under the cod on the clutch the spring hook on it rod keeps it from slipping off. I then drilled and taped a two 3/8 holes between the rear chain tensioner and side frame rail this allows me two seperate places to adjust clutch srping tension.



here is another view of everything from the other end. Now that the drive system is complete I have one more thing to do before going top side and thats assemble the EC front axle. That will be the next picture.

Your clutch setup makes me jealous... I need to build one like that, I have enough spare pulleys and other crap laying around so I should...

George....It the pivot point of your clutch setup mounted directly to the chassis or is there a backing type plate used?

It is mounted directly to the chassis the front sub frame to be exact. The center pivot bolt is a 1/2 shoulder bolt. There is a 1/4 inch spacer under the clutch plate to raise it to the right height. I drill a 3/8 hole and on the top side of chassis I use a flanged nut to tighten it up. I do not use a back plate It is right next to the end of the plate and it has a rolled lip on the end Its very sturdy and have never had any problems with any of my clutches mounted this way.

Ok here is the front end with all the parts assembled. At this point slip 4 wheels on and I have a rolling chassis. With everything on the bottom done time to flip it over and finish up top side



Ok I have slipped the fenders on to bolt them in place to check rear wheel clearance. and fit. In the up coming pictures you will see a mower can be dropped to 4 inches and clear tires without one cut on the fenders or body work. You see in the above pic the fenders mount on the running boards in the original location.



here is a picture of the fender and seat mount looking from the rear and under the fennder. Useing the original mounts I added a 1 inch square tube on top of it to raise the fender 1 inch.

Here you can see the fender mounted and bolted down I used 5/16 button head allen bolts to bolt it down. I had to redrill and tap the holes into the squre tube the fender now sits on. These bolts allow the seat to sit dang near flush on the fender. Also allows the seat to slide back and forth easily on the bolts. As you can see the factory seat mount allows this. Its legal to do. And is a great fine tuning asset in handling.



With my tallest tire on the mower (turf Masters) you see they fit and still have right at a 1/4 inch clearance. And the chassis is 4-1/8 inch off the ground on the rear. And nothing has been cut.




Well here is an over viiew of the fenders with tires on and dash slipped in place with seat on top. With this done I can now slip the steering column in set the steering wheel height and finish the steering link to front axle. Dang almost ready to slip a motor on and test it out. Thats all for tonight. Will do more work tomorrow and get more pics. Hope everyone is enjoying this build. A teaser for ya. When this one is done I and my son is going to build another just like it only using a 820 transaxle and jackshaft for the super Stock/imow class. Anyways I am done for now.

Oh Man, Just looked into this lmr deal. I'm hooked.
 
   George , your build is great for me as one of my mowers I want to build is a MTD, looks just like yours. I'll be referring back to this often.

   My other mower is a Murray. How similar are they to the MTD?
