Tractor pulling transmission building Part 1

Lots of machine work, parts making, figuring, redesigning and a discussion about factory tolerances. This video was getting too big for anybody to bore their way thru so I have decided to make it a multi part since I am making multiple parts. Feel free to ask questions as this has really been a rushed deal and my go pro battery must be on the fritz as it keeps dying on me after maybe 30min of filming so I didn't get a bunch of stuff on video. Sorry!

Nothing in the world like a get-er-done, hands-on mechanical engineer. There's no way you could design this and explain it to an everyday machinist. It's one of those, "Get out of my way and let me do it," kind of things. :-))

[@terrycannon570]

Brian I absolutely understand your explanation of manufacturing. I was the Manufacturing Director at our plant for years . My policy was "We make parts to the blueprint.. We do not make perfect parts" if it does not meet the blueprint then it is defective but there are always tolerances built into the blue print to allow for manufacturing at quantities that are profitable to the manufacturer . Thanks for pointing that out. I love expert craftsmanship but sometimes I just have to cringe when some people are trying to hit the Bulls eye on a hole that has a mile of clearance engineered into it.. Thanks again for keeping it real.

[@bcbloc02]

It is like center drilling for a clearance hole, it isn't needed.

[@MyShopNotes]

Thanks for sharing Brian, I never get to see this big stuff in real life. I really like your explanations of what needs to get done.

[@bigcountry1165]

Brian you explain things that a lot of people don't get and in a way that most people can get... you are right about all the different factors... good job.

[@bcbloc02]

Thanks!! I try. :-)

[@bigcountry1165]

Watch out fer them coyotes...

[@bcbloc02]

I have ways to handle them. :-)

[@bigcountry1165]

Me too... lol

[@smileydekock7708]

You are sure handy neighbor to have around,nice job,thanks for the talk on clearances

[@briankirsch5859]

Brians rhe definition of a true workin' American!

[@rickbrandt9559]

another knowledgeable presentation. Thanks The grandson likes how you can pronounce "Brian" with one syllable Bailey approval

[@JBOBCAT59]

Looks to me like you do very good work.Keep up the videos!

[@bcbloc02]

gerald boucher Thanks! Sometimes it seems a shame the work I do ends up hidden inside a machine, but if I don t ever have to see it again at least I can know I did a good job! :-)

[@Dudleymiddleton]

That is one serious gear box man

[@geneintn9320]

Excellent video, as always

[@thedge7]

Thanks for sharing. I would find it interesting to know the reason for the mods you do for these pull'n rigs. More explanation would suit me fine. P.S. don't skip videoing any work you manage to do on the new shop!

[@bcbloc02]

thedge7 When I finish this project attacking the new shop is next!

[@turbocobra]

Good update Brian. Love seeing those big engines. Can you share what a trans build like that costs? ball park? Thanks for the video...

[@bcbloc02]

turbocobra Parts and machine work added to the customers original trans about 10K which includes the 8 disk clutch.

[@Dan.Whiteford]

Quite fascinating to watch and listen to your explanations of what you are doing. what is the bigger input shaft from and is the hydraulic pump for a specific lubrication purpose in this transmission? What are those last components you were working with? - Clutch packs or something totally different?

[@bcbloc02]

Dan Whiteford The input shaft is from a big 4wd tractor, which needs more capacity because it drives 8 big tires instead of 4. The hydraulic pump is the pressure lube for the trans but also provides steering and brakes. The last piece was the clutch pack for the planetary gear set that allows shifting up and down on the fly. I machine and add clutches to them to get them to hold the extra power. Any more questions feel free to ask!

[@numac12]

Brian, thanks for the video..I worked for a Deere dealer years ago and had the opportunity to work on a couple of those transmissions. I was wondering if you have needled any differentials for the pulling guys. I would enjoy watching that process..thanks again.

[@bcbloc02]

+numac12 That was one of my 1st videos, looks like I have at least improved them since then! lol kzbin.info/www/bejne/ZmK0Zn-cg9KjnNU I need to film another one of these in the future that is better quality.

[@phuzzz1]

Hi Brian, throughout the video, I kept thinking about the spacer plate, I know you said it was a burn out, but is it actually flame cut, or plasma or waterjet ? I ask because it looks as though it still has the mill scale on it and I was wondering if you had to true the flatness up on both sides from warping, I would have thought with the mass of a piece that size with the thin walls, the stress from the burning would warp it some. I'm guessing you put the hole pattern in it, I'd have to think that was no easy task either. Great job, great work, looking forward to the next part, and if it's OK with Bailey, it's OK with me! LOL Mike

[@bcbloc02]

Michael Reggie I think they use a big plasma, it definitely wasn't water jet cut, it could have been power torched but if it was it was a damn good one. It is still good and flat and yep drilling all those dowl and bolt holes in their proper locations is no small feat, especially when you have to decide where those locations are since I have no blueprints. Thanks for the compliments Mike. Brian

[@dougankrum3328]

..hard to tell what they cut it with....I've done a lot of OX-ACET and Plasma....this might be plasma....it can be done underwater to control heat, and the new high-def stuff gives very clean cut edge, but a slight angle is usually left....this piece appears to have some finishing done later.....Waterjet maybe, but slow and not used too much on carbon steel plate.....both have about the same resolution....maybe .005" or so....12-15 thou kerf....

[@RyanWeishalla]

Not enough noise when you were boring it...had to look to make sure I hadn't hit pause. :-) Nice job.

[@THEIRONWORKER]

Its nice to have lots of parts to make things better with some machine work and thinking time. Is this for a Pro Stock or other. We have are first pull in about 2 weeks Good Luck

[@bcbloc02]

THE IRONWORKER This is for a limited Pro (4.1)

[@THEIRONWORKER]

bcbloc02 OK so a true Pro Stock would be a component style rear end and a limit Pro will have the stock rear and the 4.1 turbo

[@frednewman2162]

How did you make spacer plate? Did you make a template or did you actually measure and layout all the holes? Was it cut on a plasma table or cut free hand? Great video and nice work!!

[@bcbloc02]

Fred Newman I gave ALRO the gasket and they burned it out so all I had to do was align it and put the holes in it in the right spot, which I laid out.

[@fredmanning6021]

How do you connect five blown Hemi’s to one transmission

[@liamjoseph3853]

I have been looking all over KZbin for that answer. I've been asking this question for decades. If you find out, please let me know, thanks

[@johnsvess7959]

I can't find an answer either.

[@19672701]

do you paint the inside with Glyptol or similar for oil run back or just to seal the cast iron?

[@bcbloc02]

Just to keep it from rusting or leaking.

[@pierresgarage2687]

This is BIGGER stuff that I machine here.... There is boatload of horsepower going by this transmission... must make one of those mess when it blows up... If Bailey approves, it must be OK!!!

[@bcbloc02]

pierre beaudry The idea is to follow Tom Lipton rule of thumb and make it too strong to ever break. :-)

[@pierresgarage2687]

Actually watching Tom do some little bit of talking and mostly work.... That became rare in the last few months... lol

[@IBWatchinUrVids]

Brian, I know this is an old video, but I've seen them in other videos, and can't help but wonder what's up with the fireplace frames in the background?

[@bcbloc02]

They are out of my house. They used to be in the barn but I moved them to safer storage. They came from the upstairs fireplaces that were closed off back in the 60's when they put in central heat and air.

[@erickieffer8440]

Me too.

[@quevicular]

how much power are these transmissions good to.

[@bcbloc02]

Been trouble free to 3000ft-lbs untested beyond that.

[@quevicular]

bcbloc02 do you run multiple motors through it? and is there a reduction box that is hooked up before that and how do you couple multiple motors. I am just curious. I dont want to waste your time. Maybe send me a website if you can on how these tractors work and what is involved, thanks for your previous response.

[@bcbloc02]

ChiefJustice Middleton It is a single diesel engine in what is a highly modified farm tractor. There is a class of multi engine vehicles in pulling called modifieds but I have not personally ever fooled with any of them. SCS and Profab both make a lot of gearboxes for hooking multiple motors together.

[@gizzo123us]

What you said makes a lot of sense !! did you design the tranny mods and what is the name of the tractor that this is going in to !!

[@bcbloc02]

gizzo123us Yes this is totally my contraption. I specialize in building things others wont. There are lots of cookie cutter parts available but if you want something new most shops shy away from it because it is a lot of work and many shops have guys that can make parts but they can't design them, as a mechanical engineer I can do both. I enjoy making the impossible possible so it suits me fine to build outside the box.

[@ianmacpherson2409]

I am interested to know why you work off the floor and not a bench? Definatly not critisizing just interested.

[@bcbloc02]

Because I lack space for a bench and the only flat surface that doesn't seem to be a magnet for everything to lay on is the floor. Someday I hope to have a nicer workspace to include a welding table and an assembly bench.

[@ianmacpherson2409]

Hi Brian That is a very good reason, every square inch of my benches are full. Love your videos!

[@treeguyable]

Friggin go pro batteries, more are bad than good

[@jimpollock4061]

I ran across this video of you building a transmission for a john deere pulling tractor. I also transmissions for these but I build them differently. I make new shafts and all new gears. All the ones I have done for syncros. I never did one for a quad range but they are similar. Heres a few pictures of one of mine. s912.photobucket.com/user/cuttergrinder/media/Small%20block%20john%20deere%20three%20speed/johndeere40103speed.jpg.html?sort=3&o=0 s912.photobucket.com/user/cuttergrinder/media/Small%20block%20john%20deere%20three%20speed/johndeere4010threespeedpinionshaft.jpg.html?sort=3&o=1

[@bcbloc02]

Yep that is the usual way they are done. I have repaired some Urmsons built like that.
