HD MTD (Honda Driven)

i will be editing this for the most up to date build progress

Parts that i started with:
Honda GX160,
20" and 15" TIRES
mtd FNR axle,
Peerless 700 (Modified),
lightly modified MTD frame.
some MISC peerless MST parts (Not in first pic)

To Do:
Drive train
new crank for Honda (has been cut short)
modify peerless 700
clutch
drive shafts
lock FNR
mount FNR
make couplers
exhaust
batter intake
Car alternator
Extensive electrical
Low oil Alert
Improve front steering
improve front suspension
12V outlet
on-board air compressor
rear skid plate
12V to 120V converter?

Done:

 i just realized i am an apprentice now... YAY!!

This is certainly going to be a build worth watching... Welcome to the competition!

here is the concept drawing. in-case any thing was unclear.

Parts: Honda GX160, 20" and 15" TIRES, mtd FNR axle, Peerless 700 (Modified), lightly modified MTD frame. some MISC peerless MST parts (Not in first pic)
other things to do if i finish the drive train:
car alternator, a extensive eltrical system (Especualy fo a pull started engine )
low- oil ALERT.
upgrade and improve front steering
better front suspension
12V outlet
on-board air compressor
12V converter?
the whole idea is to have an auto motive style drive train. with a custom IN-line tranny (Meaning not changing the orientation of the shafts.) then a rear diff, i wont do rear suspension, because of how it will need to be set up.


engine will sit about here, with belt and clutch behind it.

then this will be mounted like a rear diff, will probly lock it.

peeress sits about here

the pearless, i bought for 10 bucks, because the input was blown out. ive pluged the hole with an old brake disk, some steel skix, by JB Weld, and some blue RTV, i will convert it to oil, but i need to get a shift fork.



it is a five speed, in good shape, i plan to use this old axle 3/4', for my drive shaft, at least one,


so, the idea is to extend the input of gear shaft to make it an input, and use an old input from the MST for the splines and to use the gear as a coupler. first i will grind out one side of the case to open it up, then weld on the shaft that will be shorter than whats shown


again, i will use the splines to make couplers that will be on the end of the shafts. i will try to draw up some concepts to make it clearer.
\
wow, it took about 25 minets to do this...................

SOME TIME LATER

ok, went out and cut open the bearing.


now about extending the shaft, does anyone know if there is an avalible extended shaft?
if there isent here is my plan/ideas.
1, since its hardened steel, no drilling unless i can find capable bits, so the idea is to do a coupler/sleeve. in this pic, that is represented by the old bearing

then mount an over sized bearing that runs on the coupler. thoughts, ideas, need some help because this is the hardest part. the coupler cold be spline on both ends so it splines up with the old reverse gear splines, then shrinks down to the out put spline sand takes up about half of them. so then its a no weld.

as of now, (3:50 PM 2/1/15) I Have the most pics

Pretty interesting transmission mods.

Use the peerless 700 that way will still allow you to have gears? That is awsome, want to see this finished up

ok, went out to heaven yesterday, (TSC) and got:
1x 5/8' ID 7/8' OD 1.5' hardened steel sleeve.
1x 7/8' bearing and housing
1x 3/16' (i think) cobalt drill bit
1x tube of RTV (Saw it, thought, Mine is almost out....)
need to get gear oil.
so, ith bit is to drill a deeper hole in the new input shaft (the one in the tranny). i had an idea and i will test this tomorrow, im in my schools engineering academy. so i have access to some slightly better equipment. my idea is to lathe out a 3/16 rod (or whatever the size is) part way from the shaft peace i am using to extend it, so then the rod gets hammered in to the old input, then welded, then smooth it out, then weld the sleeve over top of it. to mount the big A** bearing, i will grind out more of the side of the case, use one of the old brake holes, and drill another and make a spacer. then up top. to seal it, the idea is the bearing housing will be very close to the case, so i could maybe seal it up with RTV. i will prob make a vent (if i can get the neutral safety switch out)the reason im going to lathe out the rod from the extension, is so it can be precisely 90 degrees and is perfectly center. (all this depends if the lathe can cut this hard steel.) then, its to mount the engine if this works, then tranny, then rear diff, (after i lock it) ill post pics later tonight
going to drive my jeep up to tarpon FL from Hudson to hopefully sell it.


Also How do i measure bold holes on a 4 hole rim?

Sweet transmission mods! Will be interesting to see how this pans out.

Center to center I guess for 4 bolt wheels.

thanks alot

Had an idea if the CNC can cut the steel, (the one at my school) , I could re-use the old reverse gear and make a super low gear for crawling in the old spot. Put a supper small gear on the input and the biggest gear I can find . use the CNC to carve out the middle of the old sprocket and the middle of the new gear and weld them together. Make it a 6 speed no reverse (I'm going to use the mtd fnr for a revers)

ok, so here are some pics!


here is a bolt i cut short and put a washer on, this will mount 1 of 3 of the bearing housing



here is where i will need to cut it flush...

so, i looked at  my old 5th gear pair from my old MST, 205, the old 5th gear was a 1:1.5, the mst set is 1:1.6666666, so i upgraded and notice that the new gear set (in tranny) has weight reduction holes, the old one does not.and the "new" set is much heavyer duty because the teeth are much bigger.

any one have a spare 700 shift fork? i need a new one

Factory lightening holes in the transmission gears... I would drill a bunch of holes through my gears if I wasn't already planning on drilling holes through everything else. Gonna take long enough as it is. Probably hard steel to drill through anyway.

it is, i need some cobalt bits just to be able to scratch it.

so, didn't get to work on the tranny,  because of a rod failing in one of our cutting
snappers. would have gotten it fixed this weekend if the piston didn't warp for some reason. but i did get two more parts that i needed. i went to the pawn shop and bought this 1995 i think Honda gx120 4hp for 100 bucks. it had a mount plate with it, and it will fit on the gx160 im using 4 HD MTD; so i don't have to make one. and, it had a small pulley on it that is 3/4' so it will fit on my soon to be drive shaft., the OD is the same as the pulley i wn=anted to use, but the ID is bigger, so i need to get a pulley with the same ID as the one i got on it. any one want to buy a Honda gx120? got it running great!. also, how to clean a rusty crank shaft, start it up and run a wire brush on it for about 3-4 minets. and how do you spell the measurement of time with 60 seconds in it? lol spell check cant find it.

Any updates on this?

U haven't made or done any thug because our welder needs a new cable. Idk how long it will take, I hope soon

I ment I not u

OOOOOOOOKKKKKKKKKAAAAAAAAYYYYYYYY. FINALLY got to work a bit. im out of school for 2 months, so something should get done. i got the new input shaft welded at the ford dealer, so that's not going to break, lol. i have a new idea for the rear drive, my friend has an old toro with a pearless 700 and a differential axle. i coudl buy it, use the 700 as a high-low transfer case. not a 4x4, thats another project im working on. mount it with the original input facing towards the front of the tractor, and then run a chain fron the output to the diffed axle.and im thinking that i could engineer something to make it a selectable locking diff. i would make the transference a 2 speed forward and 1 reverse. i would use the original 1st gear for low and the original 5th gear for high range. so low would be ABOUT 7:1 , and high would be 2:1. These are guesses, i don't have my hands on this pearless yet. that idea would give me 10 selectable speeds, more than i need, i could have 25 if i use all 5 speeds in the soon to be transfer case. we were able to get the old hub off of the engines crank, so i don't have to get a new crank. i will upload some picks later.
