I have a 1976 C-120, 8 speed, that has had a bad rear axle key way for about 35 years.The plastic steel we put in to keep things together finally gave up the ghost last year. I tried some welding but that hasn't held up either. My question is will the rear axles from a C-81 8 speed fit in my transmission? According to the parts lists I found on this site, both trans have 1 1/8" axles and 8 pinion diffs, but the axle part numbers are different. Any help is greatly appreciated. I'm brand new to the site and think its great!

Hi! I have a 1968 Electro 12 with a Sunstrand hydro transmission. I acquired the tractor over a year ago, not running. I topped off the the tranny fluid w/ what I thought was ATF. Unknown what PO used (this tractor was so bastardized with repairs/maintenance's.). The hydro had no hoses or lift cylinder; the PO put large hex bolts into the tranny ports. I am going to purchase hoses from Lowell @wheelhorseman. What do I do?? Next? Original manual calls for 10w-30 oil for transmission. The Service Manual was updated in BOLD TYPE to use ATF type "A". Confusing???

hi guys and gals
im new to this forum and a new owner to a used 1970 wheelhorse electro 12 model # 1-7255
i paid 20$ for it off some guy knew nothing about it nor did i try and see if it ran. what caught my attention was the hydraulic deck lift and i wanted it!!! so i brought it home cleaned everything up to find out mickey mouse had a nest behind the gas tank and a few wires were chewed. i also noticed a few switches and a flasher relay in there. I think someone hacked it all up. and i dont think this tractor had any of them but i want to get rid of the useless garbage and re wire this whole thing the way its suppose to be. ive searched everywhere and cant find a wiring diagram anywhere!!! also maybe someone can tell me what these controls do? i know the big white switch is head lights and obviously the key is ignition and start and the big knob to the left is the choke but thats all i know. the little metal switch is an on/off switch to what i dont know and the one next to it is a 3 position switch in to i dont know. and the white in the top right has a flasher relay connected to it. If someone can tel me what belongs there and what doesnt i think it will make more sence. Like if there doesnt need to be a fuse in the circuit like the 69 charger diagram ive been seeing then ill re wire it accordingly. But then i see brake lights in a diagram its all a mess! I dont know what belongs and what doesnt
im also missing misc. parts like the mule drive which i know, boogey wheels and im missing a cover that goes ontop of where the shifter would go if it was a 3-4 speed. can anyone tell me what the plate is called so i can try and find it on ebay?
thanks for your help i will answer any questions oupload any pictures you want to help better your response
by the way!!!! this has a foot throttle conversion before anyone says anything about the trottle missing. it does have the electric pto. and i know the fuse holder is broken.

Ok , been asked a lot of questions about how I rebuild front axles - unless they are physically broken no axle is really past the wear point of being rebuildable .
I'm starting with an early D series front axle and upgrading to a later model D series 1" spindle type with the heavier casting . Since I could never find any pics of a comparison - here we go....
If you look closely - there is an obvious difference in the castings at the spindle end - the later model axles were thicker and larger diameter to accept the heavy duty 1" spindles. Later model (post '75 , I believe).
This photo really shows the obvious difference in diameter - early models were much smaller and a thinner casting for the early 3/4" only spindles . Need to find someone with a tape measure and one of the oddball early D-200 1" spindle equipped tractors to find out if those were a thin casting or the thicker type .
The machined relief is for the roller thrust bearings that were originally used - if you ever buy a D or I believe the 520's , this is the first thing to check as many were never properly greased and destroyed that bearing . This can really wreck an expensive spindle and make it more difficult to rebuild the axle casting itself . I will be re-machining these reliefs to mimic the factory design to keep dirt out and retain the grease inside the bearing .
Early castings , at least on this 18 Auto or D-180 that I have (missing the stupid id tag completely) measures roughly 1-1/2" outside ...
Later model upgraded casting is a whole different animal - there are major differences in how they were cast and not just at the spindle ends . Later models were 1-3/4" on the outside .
Since I've never seen a new old stock replacement I'm not certain as to the original finish quality of the machining on these things - it is obvious that over time dirt has entered and a lack of proper grease results in the bores being worn badly - some are literally egg-shaped , especially tractors from the late 60's with high hours and heavy use . Snowblowers and other heavy front implements of course accelerate this wear issue - I'm out to cure that and make the unit more serviceable .
The biggest , #1 problem with these is how they are greased . I've bought and sold tractors for years and had some that had huge grease balls around the spindles , inside the wheels and all over the front end . At least they were trying but the wear is almost no different than one that was seriously neglected . With the weight on the spindle , the grease is forced upward and exits at the E-clip at the top , never lubricating the bottom where it rides on the spindle base for the steering arm .
The correct way to grease these things is to lift the tractor BY THE FRAME , NOT THE AXLE ITSELF . Also , do not lift it by the front mule quick attach - you will bend the cross rod for the latch and destroy it . Best way is to use a block on the frame itself or make a spreader to fit the jack , maybe I can take the time to get pics to show better ways to pick these things up since they aren't exactly lightweight ...lol .
No make or brand was exempt from this issue , they all did it . The problem becomes parts availability - there are only so many parts left and finding good spindles and axles is becoming a serious problem . Some brands aren't too bad (such as the green ones) since they still support most of their older models . Unfortunately for us - Toro has chosen to drop these parts and stock is quite limited . I got really lucky and a parts dealer friend had a pair of NOS 1" D series spindles , one of the last pair to exist to my knowledge . Those are getting blueprinted and angles mapped for later - I may tackle making new ones in both the 3/4" and 1" versions . I believe with a little engineering the earlier models made in the 60's could use a sort of generic spindle since there little difference in the many models - it was mostly down to the axle's angles and width .
My D will be upgraded to heim joints for the steering . Many of the tie rod and drag link ends are NLA and finding steering arms that don't have the tapered holes wallowed out is getting pretty tough . The low angle taper on those automotive style ends allows them to work loose despite having fine thread castle nuts and cotters - the force required to turn the wheels due to the above mentioned lubrication issues , combined with a gear reduction Ross type steering box makes the holes in the arms wear - I've seen 4 of these spindles on different D's all worn the same way with the tapered factory holes oval in shape and the shanks on the rod ends could be easily turned with a wrench, which should not be possible .Converting to heims is not too hard and less expensive in the long run - the only issue being the left hand threaded rod ends at the steering bell crank (or idler arm) . Since it sits so close to the underside of the frame and being tight quarters we may have to resort to using a reduced size heim joint which are easily obtained if you know the part number systems . I have a NOS pair of factory rod ends (ball joints in the parts manual) so this one won't be getting this upgrade for now .
The factory bell crank is subject to wear like everything else . It's buried up under the engine and I suspect most were neglected being so hidden . Inside is a steel bushing riding on the cast iron bore of the bell crank . The retaining bolt , bushing and iron casting all get worn - which results in sloppy steering . On a D that's a real problem since their turning radius is huge to begin with . I've modified mine slightly by moving the turning arc point of the drag link inward by 3/8" - when it's done I'll test and measure the turning radius to see how much it helped and if there is any interference or other issues . Models with working turning brakes in either the stock D-200 or kit-equipped smaller models of course helped when in dirt or grass - just never use those on pavement or hard surfaces since it can really bind things up and possibly cause rear axle damage . It's all mentioned in the manual and instructions for the kits to add turning brakes .
Not sure yet if I'll just make a separate thread on the steering parts or include them here - plenty of info to make a long thread on the cast iron axle alone . Depending upon how well it works out I may offer this as another service to the long list of other parts I build or rebuild currently . Guy with a lathe , far too many tools and a TIG welder must stay busy during the long winters....lol .
So far, it hasn't been a cheap venture - tooling bits and parts totals are well over $400 and climbing - haven't really started any machine work on the axle as of yet since I'm still waiting on one tooling bit . I will try to document what is used in the rebuild and a parts list as well as sources . All bushings and bearings used will be off the shelf parts so it's nothing that isn't easily available . Lathe work my be required to avoid using custom ordered parts and their associated extra costs .
Anyhow , more to follow....

Going forward

I recently acquired a nice Electro 12 with no attachments. I don't plan on using it as my main mowing machine, but I would like to have a deck anyway. I have a newer 36" SD attach-a-matic deck. Would it be easier to sell/trade this deck and find a correct deck for the Electro, or convert the Electro to accept the attach-a-matic implements? I've heard the conversion is not that difficult.
