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



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.

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.

Here you see the steering column in place inside the dash area.



Here is the pitman arm on the end of the shaft The next photo will show you the depth from where it comes thru the frame to the bottom of the frame.



With a striaght edge across the bottom of the frame this give you an idea as to the exact location I have it in. Just for you to know I make my pivot points on the spindle from center of king pin to rod bolt hole 4.5" then on the steering column from center of column to rod bolt hole anywhere from 2 to 2.5" I went 2.5 initially on this one but moved it in a 1/4". Just a bit more detail for you all to digest.




Here you can see how I gauge where to cut the sfaht off at. I leave it long enough it serves as a stop at full right turn. I don't have a stop for left turn I have never went over and The tire hits the grill before it does so it serves as a stop. I don't use that much left turn. Now the right in counter steering yea I sometimes hit full lock.



here is an overall view of my steering set up with the E.C. Axle. I have been using this setup for going on 5 years now. I love it 1/4 maybe a tad more is all you will ever turn the wheel in a race.



here is a better overall view of the steering and front end with tires on it.

Now I am mounting the front grill mounts. I clamp a straight edge to the frame to be sure I am straight with the top of the axle and frame and then use a straight edge to make sure I am not at and off left or right.



See here I am checking to make sure its square to the axle. The hood mount holes are 11.5 inches center to center Frame is 13 wide so I went 3/4 of an inch from the side of frame and drew a line on the axle beam to know where to place the mounts.



Here you see both mount welded on and notice How I have drilled a hole stuck a bolt in and welded the head to the tube. Makes it easyier to remove the hood and grill simply spin the nut off top side don't need two wrenches to do it.



here you can see how it sit right over the bolts To secure it a couple fender washers and flannge nuts and done.



Here is the first view of the rolling chassis with the body work mounted. Using the hood and grill from the 04 chassis was my back up this year.



Here is another view of it. Tomorrow it will come out of the shop for the first time for a better photo and I need to clean up a bit before continuing on with it. Still have to fix the battery mount location  and some tabs welded in dash area for upper grill support location, brakes motor and wiring then body work to paint it.

First trip out of the shop, thought I would snap a couple pice with the present BP beside it.



heres another shot of them. Now to finish up a couple things (deck) grill support mounts, battery location.



Ok I put my battery behind the steering column under the dash. Here you can see I use 1/4 tubing to keep it located and I will run a aluminum bar across the top it won't move at all when top bar is on.




Here you see the back of the battery is up against the lip on the sub frame. Just to the right you can see the flangenut that holds the clutch assy.



Here you go the battery with dash on will be pretty concealed when fuel tank is in place.



On MTD's without side panels to hold the grill they have two rods that attach to the dash. I weld a 1/4" thick flat bar to the dash support cage So it has something to bolt to besides the plastic dash

here are the grill support rods bolted to the dash and bar I weld in I drill and tap for 1/4 threads then simply run a bolt in no nut and makes for quick removal.


Here I weld a a bolt to the front of the side panel to hold the hood latch.


here is the bungies I use to latch the hood cheap a whole bag full at walmart for 3.99 like 20 mix sizes.



Ok one last thing to do and it will be done except the body work and prep for paint. and thats the deck. Above is all I use of the original deck. Rules state you must use original steel deck Well I do but just a little bit of it.


I hold it up to the running board and mark my line on each end so I know how much to cut off the bottom. I want it the same thickness of my running boards.


This is a handy tool an aluminum yard stick. Very flexable makes a good straight edge even on rounded surface. I clamp it on one end then hold it on the other and mark it with a sharpie. Then cut the bottom off.

Well between working on customer mowers and racers, and having a bit of the flu I got out to the shop today and installed the brakes. First picture is the rear brakes with lines attached.


Below is a close up of the Hegar front brakes. The axle is keyed with a 3/16 key and has 2 set screws to keep it tight. Never had any trouble with these brakes.


Below you see both front brakes on. Next I will post the running of the front brake lines. I did something a little different there.



Ok many of the MTD fenders have cut outs on the left side that allow the lines to go between the fenders and frame. Very nice fit and makes less work.


Ok here is where I stepped outside the box.. I bought some brake tubing from napa and ran the nylon brake tubing inside it. Keeps it from vibrating and gives it a cleaner look. Also some extra protection. I run this one down because the headers will be right there and this keeps it off the headers.


It also runs up and inside the frame around to the right side behind the steering column infront of the battery. Again extra protection of the lines.


Here it is a simple run right down the right side right on top of the chassis. No headers here to dodge or get around.


Ok here you can see an aluminum plate. I used this as a back plate for the master cylinders to give them support so it doesnt flex the side panel. Also where the front brak lines go thru the side panel I used a rubber grommet to keep them safe.


Here are the master cylinders mounted and the all lines attached.



Here is my mechaincal brake bias. Very simple setup and I am going to make it adjustable on the fly from the dash. That will come later. It adjust from front to back.

Ok a couple things in this picture you should notice. the first notice the corner how I have taken a 4"grinder with a flap disk and rounded the corner. And also the shims between the actual wheel hub and the brake caliper assy. This is some times required because the caliper will just run the back of some rims. Note you cannot use a rim with more than 2.5 back spacing. True Roll rims do not hit. The ones I have are Circle/Van-k and I believe they have been bought out again by another company.



Here you see the rotor and the pins/dowels it floats on. When shimming between hub and caliper be sure you do not shim so much the rotor will float off the pins. This could result in a nasty ride at the end of the straight.



Here is an up close look at the mounting I make for the mph sensor which connects to my Digatron Tach. It is a magnetic type switch and trips everytime one of the dowles the rotor floats on passes by them.




Above you can see the new battery in place. I have some scrap aluminum angle pieces that I used to make the hold down. it goes over the rear top corner of the battery and as tighten it pulls down and forward locking battery in place. Also notice the rubber cover over the postive terminal. A serious must do.
