Hands down the best instructional video anywhere on the internet or youtube.You covered every entire step to rebuild a short block for the kubota engine..Great job Brady and crew

[@tetradgroup]

Wow, thanks!

[@creativecreative9582]

@@tetradgroup Amazing instruction ,thanks ,subscribed and liked.

[@hddoug72]

If and when the time comes on my 743... this series will be very beneficial. Thank you Sir for the time and effort to provide us with a quality how to guide!

[@wademizelle3433]

Great, great video, I plan on watching all of these videos. Be sure and film installing the engine back into the Bobcat. Thanks

[@keithculhane5463]

Thank you for filming this!

[@tetradgroup]

You are so welcome!

Another trick, when fitting bigger oil seals. Fill the gap where the spring is with petroleum jelly, and it will stop spring from jumping out.

[@viixxi1983]

Thank you for not gatekeeping info

[@user-bw3pk5dw9c]

Thank you so very much for this video! I'm in the process of rebuilding a D18-3 and this is too helpful!!

[@Z-Bart]

I had a 3 cylinder Volvo diesel in my boat. I would have loved a marine Kubota about this size 40 Hp. Very interesting watching you build this.

[@tetradgroup]

Very cool!

[@KarasCyborg]

These videos are solid gold! Even the candid video parts will save someone a lot of headaches because it shows the how the thinking process needs to be. Like the table part layout. So glad there isn't Charles Manson Music blaring in the background so I can hear what you guys are saying. This shows the level of skills, experience, tools one would need to be able to do this properly. I know I have asked before, but approximate hours on machine or motor when things like this need to happen would be immensely helpful. Would also be helpful to know what like of business the machine was primarily in: Forestry Mulcher / Snow Pusher / Site Prep / Landscape. It's nice to know if it was a premature failure based on your experience as well. Fair cost on the rebuild would be nice to know as well.

[@tetradgroup]

Thanks for the questions, this machine has about 3000 hours on it. Landscaping was the primary business for the owner. This engine spun a bearing and broke a connecting rod on one cylinder and melted a piston on another cylinder. I had to replace one liner and bore other cylinders over .5 mm. I also had to replace the crankshaft. The total for all parts, fluids, and machine work will probably be around $3000 not including labor. Failure was probable due to a bad injector which melted one piston then it started consuming lots of oil then probably ran out of oil which spun bearing and broke connection rod.

[@Superdavellc]

When I rebuilt mine, forgot to check the ring gaps, and I did none of the other checks 😂. 30hrs on it and so far so good 🤞

[@martincassidy4839]

When measuring piston ring gap, it is better to put a piston ring on the piston. So when you put the piston in the bore, the piston will sit on the ring, making sure your ring is straight in the piston bore, giving you a perfect measuring

[@YooooouKnowwwww]

Love love love it! Please keep making these!! They are awesome

[@tetradgroup]

Thank you so much

[@markm0000]

Wow thats a lot of good info I never learned. If I ever get thrown into a bad situation now I have a general idea what I’m doing. Thanks

[@kenbutera3530]

Good video, with a great mechanic. Wish you were still in Gwinnett. 😊

[@tetradgroup]

Thank you. I do miss the south!

[@en8581]

Thanks a million- this is an awesome video! I have owned a diesel for 10 years and do my own maintenance and had a general idea of how a diesel works with camshafts/timing but this made it so much clearer to me. I am getting a boat soon with two Beta 50 engines (this same Kubota V2203 block I believe) so this is helpful. This may be a dumb question but (anyone) if I want to slowly manually turn the engine, eg to make sure not seized, with the engine installed in a tractor or boat in my case, how do I grab onto that spline on the front of the crankshaft to turn it? I see some other engines have a nut you can put a socket on but I don’t know how to do it with this Kubota V2203.

[@lucmarchand617]

This is reason many bobcat end up in auction because cost rebuild engine.i know people here calgary alberta pick up lots bobcat repair with oem parts rent it or sold later.most is due lack maintenance very sad part yes sad but true.this video top line period.thanks😊

[@lukemorley7481]

A wealth of knowledge

[@user-bw3pk5dw9c]

I torqued a connecting rod bolt to 30 (not 35 as recommended) and snapped a bolt! had to get a new connecting rod

Fantastic video! Thank you! I am rebuilding my D902. What piston to cylinder wall clearance do you run? I have not found this in any manual or on forums.

[@jesselassiter14]

kubota v2403-M-DI vs kubota v2403-M-DI-T. Are there internal differences with the engines or is it the same engine with different intake/exhaust manifolds and a turbo?

[@purwantoanto1440]

how,many lbft, tigtened bolt stang piston?thank , very nice

[@wd2699]

Just to make things clear. If you buy the kit with the Liners, you need to bore the cylinders to install the liners?

[@tetradgroup]

Yes

[@juana.damiantarazona7507]

Podrían mostrar como se puede extraer el tanque de combustible de Bobcat, lo agradecería muchísimo, gracias.

[@thepubliceye]

If one of those mains gets damaged I would think you would have to buy a full replacement set and not just one?

[@josuemorales1387]

Hey so I have a engine that what I was told broke a rode and made hole on the block and telling me the material the block is made of something you can’t weld on and had to replace the whole engine I wanted to know if it was true and if I should rebuild it or buy new it’s from a older skid steer

[@josuemorales1387]

Excellent video by the way 10/10 best one out there I looked into these videos like 3 months ago gave up because I couldn’t find a good one then I had nothing to watch so gave a try and found this video excellent and very well explained

[@markm0000]

Anything metal can be welded with a skilled welder, but it’s not a good idea to fix a broken block. It’s expensive to rebuild and the shop can’t guarantee their weld since the block could have internal stress cracks in it that you can’t see. That’s a lot of money down the drain if it cracks again and you’ll blame the shop for it. That’s why they didn’t do it.

[@markm0000]

These engines are everywhere just get a used one.

[@oiu7890]

Are the torque values for wet bolts or dry?🧐🧐

[@tommyk1073]

So those blocks do not use liners? It looked clean, no liners. Great video..👍

[@tetradgroup]

This block had one liner replaced and all cylinders are bored .5mm over.

[@scotyarnell1157]

Love the videos. But the part with the guy with the lightning strike tattoo on the video needs edited out. That’s a white supremacy tattoo whether it was intended or not. Like I say, love the videos just trying to avoid fallout.

[@oiu7890]

All the rebuild kits I have seen have sleeves included.🤓🧐

[@tetradgroup]

The kits with sleeves come with standard standard pistons. I ordered a kit with .5 mm over pistons. I had to sleeve one bore and then bored all cylinders to .5 mm over. This option was more cost effective for me due to the cost of installing the sleeves.

[@straycat9754]

Nice careful assembly! Eliminates second guessing later on. What would you do if you had too much piston protrusion? Thanks for getting the younger guys involved.

[@mcl237]

Do you sell rebuilt D1005 motors? I have a core

[@timstanford3443]

Where is part 2?

[@tetradgroup]

Still working on it, had to wait on some parts to arrive.

[@MisterWhippy4win]

So are there no cam bearings in the block that need measurement?

[@Katchi_]

Very few diesels have cam bearings. This your first day on the job?

[@MisterWhippy4win]

@@Katchi_ only rebuilt gas engines but I have a Bobcat T595. Just trying to learn the equipment. Thanks for the input, bro

[@derrickcook8593]

I would like to talk about newer style 510 560 590. I'm not to impressed with the hand controls. The old style with hands and feet seemed more responsive,even with all the speeds turned up. You don't get full forward drive speed right away...it takes a few seconds. We load bales of cardboard not dirt or stone. Sometimes you need full forward drive for a split,older machines you could that. New machines not so much. Am I missing some setting or is that the way the new machine are now?

36:05 Aahh, the ol' superduty front axle vacuum seal install tool to the rescue! Absolutely need that to put your 2 piece vacuum activated hub seals on the axle shaft & then into the knuckle. Nice use for a tool you rarely use but need to have if you own a 2000's superduty w\ ESOF vacuum activated hubs 4x4.👍🏻👌🏻🛠️🔧🔩🦺😎⚠️🤔🚧

[@tetradgroup]

😆 Not many people would know what that tool is, good eye. Working on a Ford at the same time and tool just happen to be on the work bench.
