I miss these kinds of videos from Fearless Front.

[@markrobison5251]

Hi Todd! I know your video has been on here for a good long while now! But I wanted to drop a line here and say that your video helped me to take apart and replace, A snapped axle that i had in my sears craftsman GT 6000 garden tractor. Like you it was a first for me to tare one down..Your video was very helpful and your tips helped me out! Mark

[@garryludwick2990]

Love this vid. HINT...On the shifter lever, use a CV joint boot to keep water out of the trans. I restore and find water, milk, in almost every trans. Water runs down the shifter and slowly leaks into the eng. CV joint looks good too

[@Ghis1964s]

Well Fearless, as we say around here in french-quebec "C'est faite par du monde" (It's done by people). Some people do this often, some as a job, some only dream of doing it, and some, such as you, actually dare doing it. The only wrong way of doing anything is to not do them at all. Keep up your good and keep having fun doing it. Peace;)

[@MrCountrycuz]

I like the work you do with suburbans. I miss my old girl.

[@moneybags9414]

laughed my ass off bout the "give er the ol motion" part

[@Fearlessfront]

Thanks man, that should be almost the same, besides the 6 gears, which I would think is better than 4. I haven't gotten the motor on it yet, but I will be getting it VERY soon, and then we will know how well it holds up.

[@Fearlessfront]

I think it will too! cant wait to try it out

[@moparfanatic63]

This is exactly what I've been looking for once again I can take care of my 1972 allis-Chalmers rear end to finally get full traction thank you!

[@Fearlessfront]

Only time will tell! I will definitely be putting through a test

[@Fearlessfront]

Thanks man, I like the steering on this one as well, it nice and low geared so it has really smooth motion.

[@JunkStarBuilds]

As always, awesome vid! That thing looks durable as heck!

[@MYNICEEV]

A very good tutorial. Not a mechanic but could follow everything you were pointing out. The best how to is the first. Looking forward to see what this one produces.

[@itchegodisturbed85]

That thing is going to be a beast I can't wait to see it in action

[@kerrydills3240]

Very informative video. I've got a Sears just like yours. Thanks for the info.

[@157bradley1]

Another great video by the way. I really enjoy your helpful how to's. I have a 1967 Suburban that I use for general gardening and food plot (for deer) work. They are incredibly tough tractors and steer much easier than most of this era. I repowered mine with a Kohler Command OHV 12.5 hp side shaft (my models was originally a Tecumseh and parts were scarce). Keep up the fantastic videos man.

[@Fearlessfront]

I actually do landscape construction. But this has been a hobby of mine for a very long time

[@marshallgregory7869]

great stuff, you do , in Tx and retired, speak lawnmower good. learn n a lot from ur videos. Keep it up. Sid..

[@mrmatt5555]

Thanks for the vid. I've made a dual transaxle craftsman with two of these gear boxes and whenever I go over a curb or small log at an angle, 2 diagonal wheels of the rear 4 just spin. This will fix my problem. Thanks again!

[@KIDZKARTBLDER]

Hay the last one I locked like that ....I welded in bolts exactly where you welded I just turned it to where the bolts Jammed and then welded them solid kinde like you did ... But I think I saw enough weld to make up for the bolts ... Lol nice video ... Perfect

[@parkerlegamer6168]

sears suburbans are the toughest most reliable mowers ever built, ive got 2 and both are absolute tanks!

[@Fearlessfront]

lol! thanks man, it'll be a fun ride for sure!

[@Otsman2222]

Very good video. The only thing I might add to it is to replace the little pressure relief valve. on the right side of the trans, with a vent hose routed up behind the dash or somewhere dirt and water can't get in. That valve only lets pressure out, not air in, which could cause it to draw in water through the seals when the trans is ran through deep water which would cause it to cool fairly quickly. I've pulled a few of these transmissions apart and they always have water in them. Just a thought. Love your tractor by the way. That thing is awesome!!!

[@MegaMobass]

The motion hahaha fearless you crack me up man, keep up the great work, i look forward to seeing this tractor move!!!!

[@Fearlessfront]

Thanks man, me too!

[@zachsgarage4714]

hey fearless, you didn't actually have to weld your gears, all you had to do is flip one of the gears on each side, so there would be 2 gears on each axle shaft on each side.

[@shiddy.]

very cool to see the inside of this

[@ShawnCFarm]

Looks like you cleaned up abit in there. Looks good. I need to get moving this week and get some videos made lol

[@Fearlessfront]

Yes, I am still planning on trying the diesel

[@808TheDuck]

That is a solid transmission for a garden tractor!

[@jordanbarakat7288]

That is the 6 speed h/l it called a lot of different thangs

[@Fearlessfront]

It's a Lincoln Electric weld pac 100

[@Fearlessfront]

I use the standard high temp red gasket sealant. you can get it most anywhere

[@slimjim119]

looks great and strong

[@bigmikesshenanigans5504]

good video nice clean welds

[@MattsMadnessOfficial]

thats the same rear axle I have in my 1961 suburban and I got a spare so I might just do this great video

[@offroadredneck101]

I have a similar transaxle in a old murray that i use for offroading and i wanted to lock it but i thought it would be hard, but your vid really helped. (:

[@zacharythole3077]

I am very surprised that locker has held up for you so long. I did the same as you, learning by the video, and my locker died quickly. I still have the stock rear tires on but im pretty heavy 250ish. Drove her around for a bit and snapped the teeth i welded to clean off those little gears. Luckily nothing else was destroyed so I was able to dissasemble and reweld. Only difference was i welded the living shit out of the little gears and then procededed to weld them directly to the bullgear or whatever to prevent them from breaking again. That has worked well. I would definately suggest pulling that apart and doing some more extensive welding to prevent breakage. Just my two cents, trying to help ya out

[@Fearlessfront]

I think so, if you look at the end of the music video i did of the antique tractor festival, there were two pulling tractors that had the same trans as this, they had 26" ag tires AND competed in pulling competitions.... Un-locked of course. So it should be pretty rugged. everything has bearings, not bushings.

[@tylertimmons1540]

Very informative! Tempted to do.

[@youngguns1057]

Hey fearless, where did you buy those seals and case gasket? I’m about to pull my transaxle apart and do the same thing as you but I can’t find the gasket! My plan is to make one but buying one would be much better! Thanks

[@sandranewton1648]

you are awesome! you really know your shit.thanks for all your vids!

[@horificone]

When you put a seal in, don't use a socket..you can still dent the seal with it, and cause it to fail. The best thing to use is a piece of wood the same diameter. I use an old wood hammer handle that is sanded smooth and square on the end.

[@Fearlessfront]

yeah, this one is 1" vs the murray 3/4" thick. it also has bearings everywhere, the murray? bushings...

[@KTMcrazy247]

I recently picked up a 1966 suburban 10, not sure if it is this same model trans or not yet. I am considering locking it but I was wondering about how well they steer afterwards. I have had some carts in the past with posi that pushed the front and made turning difficult on road. Does your Sears push the front on road?

[@projektoffroad]

Can't wait to see it finished :D Are you planning to use the 10hp diesel?

[@chimaira3134]

great video Fearlessfront do you have part numbers for all of those seals and a website where you bought them? i have to Sears SS16s that im going to be working on.

[@bobhunt3197]

"THE MOTION" you are one funny fuck, good vids always learn something here. Thanks man.

[@Fearlessfront]

yes, I am

[@Fearlessfront]

well, the hardest part is getting it in, and out of the chassis.. this thing is HEAVY!

[@Fearlessfront]

What mud digger said, the fuel tank is above the carb so gravity does the work

[@wvresident7004]

Using a socket on the new seals is a good way to do it but I find a better way to keep the tool centered with each hit of the hammer is use two pieces of steel pipe nipples that fit into the seal (1/2-3/8") and a coupling. The pipe goes into the seal and the coupling is what presses the seal. This also works good for other seals or bearings

[@gwolf1942]

cool it looks good.

[@Fearlessfront]

I know what you're saying, thats not a bad idea though. I just heated the crap out of it with the welder. I think it'l hold up.

[@redneckbryon]

I have a Craftsman GT6000 with the same transmission, I'm thinking about locking it but I think I'll wait to see how yours goes first, lol

[@NicksGarageDoorService]

Those planetary gear differentials are awesome, a lot of R/C cars use those, but they are usually in their own plastic case. So what I'll do is scrape out all the grease and use red loc-tite on those diffs, then re-install them after 24 hrs... Obviously it wouldn't last here, but what you've done is essentially the same, but with welding. I've never had a problem, so I don't see why you would. :-)

[@THEMOWERMEDIC1]

JUST LIKE THE DIFF IN A SNAPPER RIDER

[@SkidmoreRacing]

amateur? you look like you know what your doing to me and that thing is gonna love the mud

[@Fearlessfront]

yes, but I was torquing the last little bit, so i didnt. I usually torque in 2 or 3 stages...

[@Fearlessfront]

searspartsdirectdotcom punch in your model # and select transmission and you'll have to pick and choose what you want.

[@Dillon1791]

I like that trans axle.

[@Fearlessfront]

Wreck it? it's gonna be FAMOUS!

[@justanothertractorguy5794]

Do you remember where you got those seals? I need a input pulley seal but I might as well do them all

[@Fearlessfront]

there is no link, you have to punch in the model # into sears parts direct, select the transmission group, and choose the seals you need out of the list, and the diagram. the parts i bought cost about $70 shipped

[@Fearlessfront]

you gotta go to sears parts direct

[@Beerpiglet]

I love all your videos what do you do for a job ? you are clearly a very skilled person are you a mechanic. Greetings from Australia.

[@connorpayeur2786]

a good tip is to put bar and chain oil in the transaxle,especially if your going fast on your mower.

[@bigbud7356]

I put new seals in a Bolens g12 transaxle and used carb and choke to clean mine and it destroyed the rubber seals so I use starting fluid instead it does not eat the rubber

[@moaski]

Have you ever considered swapping out your pulleys and belts for sprockets and chains?

[@919055]

he wears sun glasses all the time cause his future is so bright

[@aronrussell4521]

I have a 1980 wheelhorse that has been sitting for about 15 years do you think the rear end is still anygood?

[@MZEng100]

@Fearlessfront Hey man i just bought a 1987 MTD mower with an MTD single speed transaxle on it. I noticed the brake shaft moves in and out every couple of rotations of the wheels. Any ideas what would cause it? keep the videos coming!

[@mikegraybill5340]

is this the same as a old mtd tranaxel i have a 4 speed and want to do this but i cant find where to buy the gasket for the case

[@Bhilderbrand]

where did you find the gasket kit I'm having trouble finding them

[@carshowkid51]

Is that the only version of that axle? Or is their a 6 speed high/low? or a 5 speed high/low?

[@anthonyelevatorguy]

You're the best

[@hardcummy5862]

Where did you get your transaxle seals and gaskets from?

[@racingreece35]

Do u think jb weld or quick steel would work

[@285yamaha]

Hey Fearless, what are your plans for a motor on that beast? Still the 10 horse diesel?

[@Fearlessfront]

that is the sprocket that came equipped on that gear box

[@bvisel4558]

Thanks for that link. I guess I should order my seals and gaskets. Did you leave your band type brake on or did you replace it with a disk?

[@Fearlessfront]

I kept it. It works pretty good. I would like to replace it at some point though.

[@cameronjohnson5833]

FearlessFront (Todd Christopher) how much oil does it hold

[@floydbarbour5098]

Hey could you give me the link that you got for those seals for the axle thanks

[@ChevyAndrew1]

fearless, where did you get the 8 tooth sprocket for your 700 series in the toro? i cant find a 5/8 splined 8 tooth anywhere for mine

[@Fearlessfront]

I know, im not drinking it, and I don't use it everyday... so it's not like i'm surrounded in the stuff. thanks

[@victoryfirst2878]

Do you know how many years these trans were used fella ??? How heavy is the unit ??? Thanks

[@corneliusvonhimmler8355]

Hey man i know this video is like 10 years old but where do you find these oil seals and a new gasket? Im strugging to gind em

[@jamesbeck9326]

Do you have the part number for the gasket, seals and needle bearing? I am rebuild mine thx

[@tatewiirre5578]

whats happening with the lifted mudding mower

[@jimmyelks6670]

What kind of oil did you put in the transaxle for the Sears

[@DanTheAngryModder]

I think by modding a classic into something else is what the viewer was referring to. I have one now, 3 years older than yours. Sure, I plan on adding a few things, but... mainly leaving the drivetrain stock. and only giving it better tires, new paint in some scheme or another, and more lights. MAY regear. *shrugs*

[@Fearlessfront]

No, actually it doesn't. I assumed it was based on what I read online.

[@AllenFravor-nx7nf]

What are the seal part numbers where did you get the gasket for the split

[@bradfordcustommudders9139]

Hey fearlessfront can you send me the link where you got the gasket and seals for this transaxle

[@johnchadwicktilton]

Which mower build did this trans-axle go in ??

[@Fearlessfront]

maine, and not as much as the shipping would be both ways... might as well buy a welder at that point

[@markluce1659]

I'm trying to find out what is going on with my trans axle. It seems like reverse is jammed. It will move forward but in reverse it won't and the belt will squeak. It's a older Craftsman tractor with high and low range. Please help

[@Fearlessfront]

no, I got it about 2 months ago

[@UnitCrane514]

At least you made it (Undoable)!

[@157bradley1]

Hey Fearless......is this transaxle actually marked "Peerless"? Does it have a high and low range? If so, I was under the impression that they were made by Roper, not Peerless. I am no expert though.

[@codymacdonald9544]

Hey Fearless, what size tires would recommend for a craftsman ( aprox. 1994)?

[@sg1dude]

Brother have you ever thought about installing left and right brakes and 2 pedals like on tractors instead of welding your differential. With your skill level and design ability's it would be easier than all the disassembly and everything would be external.
