Well this one has been a challenge trying to get everything in tight yet 4" off the ground and use 8" rear wheels per US rules. I have cut it upo and started over several times but making progress. Phillip sorry for the time this is taking but I think when done you will be very pleased.


Here is the transmission in. I have slid it forward a bit Phillip wants the walk thru but it will not fit completely under. I have several things to do to make it look like it belongs. I think this is gonna work well.


Dash is mounted this being a twin it will need all the room it can get under the hood. The tank is notched in back to fit around the column, so I notched the factory mount slid it back and up a bit and got a bit more room.


Just a generic side view nothing special here.


Here you can see the original tank mount how I notched it for column clearance and the column in place this is the original column used to mock up mounts.


Bottom view of front axle beam mounted.


Bottom view of transmission mounted and clutch and idler. Things are so tight the idler sprocket I generally use will not fit. But the flat idler will do the job.


Close up of inside frame work for rear axle mount.


Clsoe up of top of steering column mount


Clsoer view of bottom column mount and tank mount


Closer look at sprocket and idler for chain showing how tight things are.


These next two pictures are a closer look at clutch.



More later. Back to work for me.

George, Your BP looks good in the build section. The only thing I do know is the flat idler won't last long. I had the same situation as you do space wise so I tried the flat idler and it was almost grooved through after a very short time of test runs. I am running a skate board wheel now with a slot lathed into it for the chain to ride in. My only issue is I wish that I had more space as some sprocket combos make half links necessary which I hate because I don't trust the little cotter pins to hold in the half link pins. I can send you a pic of my flat idler. I don't know even an micron as much as you on racing mowers but I wouldn't run another metal flat idler.

Well its not my BP, I am building it for a customer. I will keep the idler in mind. I work in a machine shop so I can machine a skateboard wheel. I have never had a half link fail. I generally put a dab of silicone on the cotter pin and also on the side of the master link and never had any issues.

using one of the donor chassis I raised the rear box since this will be using 8" rear wheels and 4" off the ground.


Looking at it from the top it looks oem thats the purpose as this machine must pass US tech.


Here you can see the fenders have been extended again using a donor. Trying to get the trans in a location that works yet still maintain the walk thru of the chassis has been tough. Messed up a few times in the process. BUT I got it figured out now.


A look under the fender the chain will be covered nicely


here is the front of it once done the trans will be covered and when removing the fenders it will all be one piece.

WOW!! That is a total different animal then what is normally cruising around here. Walk thru design is tough. Mine was a walk thru style but i had ample frame to work with. This thing is definately a tight fit george. But my only question is on the trans and covering it up. In US you can not have any of it showing correct? And you mentioned a cover for it, kinda like a "molded" in bubble in the fender so it looks factory? that would be awesome. or will it just be a bolt on cover? Anyhow, looks great

Larry's been using a flat idler like that on his for a chain tensioner, that mower has probably at least 30-40 races on it and no problems. Maybe you just had a bad bearing rc, I dunno? He managed to get his tranny under the fender...barely, man those things got no room in there!

Ok back on it. NO MORE racing nothing till this thing is done. Want to Give Phil a CHIRSTmas present.  Here is a view of the left rear from the front with wheels on.


here is a look at the trans and fenders in place. rear end is done. Clearances are good.


Here is the rear view. Will get started on Chain guard tomorrow night.


here is a side view. Pulled spindles off makeing a change or two there. But its 4" off the ground, fenders and tires fit nicely and look natural. Motor fits in under the hood quite well. Took a bit to get it right for air filter. Once finished with battery compartment I will show it. Think yall will like that.  But we are back  to work hard at Herrin Mower Sports Chassis and Engines now that the season is over. This is what I enjoy the most

With the Tank in low I had to do the same for the Battery. Down low and left. As you can see its set down in the chassis


See its a tight fit but is in the chassis safely tucked away


A bit closer for you to get a better view


Looking under the chassis you can see how I boxed it in for the battery to sit down in and yet be protected.


Just a general view of the front of the chassis

Chassis is reinfirced for the motor. I used 1/8th thick flat bar this also levels the mounting area


Here is another view of it. Ready to sit motor on and add the pulley and get a belt size. Will post those tomorrow.

Ok with motor on and all pulleys and clutch mounted I run a long belt thru all the pulleys except I go around the edge of the rear. Pull tight and mark the belt. Measure it and this gives me the length I need.


Here is an overall view of the belt and pulley system


Here you can see where I pulled the belt tight clamped with some vicegrips and i then mark it take it off and measure from the end to the mark.


Here is how I do the bolt for the clutch rod. I put it in a drill and whilespinning it I turn it down using a flap wheel on grinder I turn it so it is beveled. Once done I use an impact and spacer and nut tightening it so it pulls the beveled head into the bolt hole wedging it in flush. Now it only required a socket to take nut off and head of bolt does not drag on anything.


Had to turn it around on the lift so I rolled it out and decided to get some quyick shots of what its gonna look like. First couple are with hood off.


Here is another view with hood off.


This is with the hood on.


This is gonna be a sharp looking hotrod.


We are using the 10" brake disk on the rear and still have to box in the slot for the sprocket which will be the chain cover.


Back to work....

Great, thanks. The 1710L is now on my build list smile

In my brief motorsport career I've seen endless people always wanting MORE POWER, but very few understand how good, larger brakes can make you faster.
