Bobcat T86 First Look From A Mechanics Point of View

@@tetradgroup What do you think of the Bobcat brand compared to other top brands out there?

[@joehilty59]

So initially I was under the impression Bobcat was going to integrate an auxillary oil cooler into this particular machine for hydraulic oil temperature control. My gripe with all the major compact track machine manufacturers is they say you can run attachments such as a Diamond forestry head or FAE mulcher and the machines will keep the hydraulic oil cool enough to run in summertime. That is not the case in any of the three machines I've tried; Tak, Bobcat or John Deere. Was hoping this machine would solve that problem. Doesn't appear they did that.

[@TheOMEGANOX]

They did solve it, and now it’s proven by scores of T86 running forestry heads in Texas and all over the Deep South last summer, I’m talking triple digit heat 8 hour days with fluid temps hovering around 150 degrees. It’s quite remarkable, and why I bought one last week, T86 is now one of only two machines that can claim this with just the factory cooling system, the other is the ASV RT135 but that’s more of a dedicated mulching tractor and riddled with issues. I’ve personally kept in touch with around 15 guys running T86’s for the last 12 months and ALL of them have been bulletproof. Phenomenal machine.

The review is well done and informative. Similar to competition the serviceability in the engine compartment looks absolutely brutal. Also, I am not a fan of the rear visibility on these Bobcats either. You can’t see behind you for love nor money same as prior Bobcat models….and this is very important if you’ve spent any amount of time operating these machines in the real world.

[@tommyk1073]

I’ve been more impressed with the past Kubota engines than the newer Doosan engines. Our S570 air box cleaner is such a pain, and the fuel rail shows so much rust, yet we don’t use it in winter. But our older T590, powered by Kubota, is night and day better..just seems like maintenance overall is easier. BTW, your videos are great learning tools.

[@KALI1080]

Hey that is a pretty nice flow testing setup! Could you do a video on other tools/shop equipment like that flow meter that you use to test equipment?

[@user-yy4ju1en5y]

Seeing a T86 I would have major concerns on its design. The T86 has exposed driveline motor lines on the underside of the machine. When mulching they will get broken. The T86 has a grate on top for air intake instead of a precleaner assembly. The air cleaner will clog with dirt quickly in dusty environments or while mulching. What looks like a serious concern to me also is the location of a good portion of wiring harness and the Ecu being located on the bottom of the compartment. Any of us who have owned track loaders know that mud and water finds it way into the bottom of the compartment. Its ridiculous to place it there. What do you think will happen to the Ecu and connectors when you get stuck in deep mud or a creek? How could Bobcat finally design a well built machine capable of mulching with the right pump and good flow only to completely F up and make critical design mistakes like the ones I mentioned. When a company is completely disconnected from the end use this is what happens. They got it right in so many ways but then totally screwed up on critical machine killing details. Thanks for taking the time to make the video to show us the machine though. Very informative.

[@andyjones6361]

Looking to possibly replace my 2018 T770 with one of these, current Hrs 2600. I've been told to bump up my case drain to a 5/8 line straight to tank. and run 1" lines to my couplers. also have a couple guys telling me to crank up the main relief valve. I mainly forestry mulch and stump grind. But if I'm beating a dead horse and its time to replace the machine I'm curious of the case drain line size on the t86 also concerned with debris getting into the belly pan. Not uncommon to find mud holes in my line of work. Not sure if its best to fix up what I have now or try one of the R series out.

[@dylansadventures4696]

There is definetly some weird stuff going on. Calculated hydraulic hp on superflow is greater than the engine output which is just not possible. Intersting

[@tetradgroup]

If the machine were running at max flow over relief pressure, I'm calculating 99.5 hydraulic horse power. That would kill the engine but the engine is rated at 105hp.

[@dylansadventures4696]

@@tetradgroup I wonder at what point does the superflow even matter? My tl12r2 high flow is 40gpm and produces 84 hydraulic hp with 115 hp but can still stall the motor with the mulching head. So is super flow even worth it because the power is unusable?

[@MrAllmotorB]

Super flow what attachments can even handle that all I can think of is a Mulcher head

[@GrandpasCrew]

Any more thought on the usage of def on these machines?

[@tetradgroup]

Well, it will use 1 tank of DEF to every two tanks of fuel. This is more frequent than the M Series due to smaller tank and the fact it does not have an ERG which requires more DEF to remain emissions compliant.

[@tetradgroup]

Excellent question, thanks for asking.

Have you looked at the D3? I believe your concern has been addressed w a new hose routing block.

[@JamesCofield-d1m]

Just curious how did you test super flow without plugging into the 1 inch fittings? Did I miss something? Or just not understand how it works?

[@tetradgroup]

One set of hoses feeds both fittings, they are the same circuit

[@GrandpasCrew]

Will this engine go thru more def? I go thru several tanks of fuel on my s-770 before I need def.

[@tetradgroup]

Not sure but that is an interesting question. I will look into it and let you know if I find anything. I would think it would last longer being the same size but more efficient engine that runs cooler due to the new design.

So If they built the machine bigger Then the room to work on would make it easier With a release to take the cab out of the way Modern battery to tuck it away nicer Sure all improvements = more $'s Theres a bit of competition now with other brands But in time Improvements will get better Like travel with super flow on Its probably like closing a value on the travel speed to maintain pump flow They haven't figured that one out yet That cab lift didnt look smooth Perhaps a cab lift that can tilt all the way over to where the roof sits on the ground An engineers dream job Thank you

Hey HowIDidIt i have a T86 throwing code C10A5-16 Pump Case Drain Hydraulic oil temp out of range Low. I was running my stump grinder when it did it. hydraulic fluid is full and hydraulic temp is right at 125 degrees when it happened, is that to cold and maybe whats causing the issue? The dealer checked the OHMs on both temp sensors and it was 745 (supposed to be normal) I guess. They cleaned out the hydraulic fan solenoid as it seemed stuck and to cold for running temp and seems fine now after being pulled and cleaned. What is your opinion is it pops up again? thanks!

[@tetradgroup]

Out of range low is possible loose plug at sensor or wiring issue. The case drain manifold under the cab has a filter on it, there you will find a couple temp sensors. Check connections or swap plugs and see if code changes.

If it happens again I will swap plugs! what should I expect when swapping plugs and it happens again?@@tetradgroup

@dillon40R depends on the source of the issue. If it's a bad sensor then the code would change to motor case drain temp code. If it's wiring then the code would not change.

The def injector is a pain to get to. V2 engine analyzer isn’t the greatest tool to help trouble shoot those engines. As far as leak back test on those injectors good luck unless you make your own fittings to plug into the injectors that will cost you about $100 for just the fittings. The oil filter locations make catching the excess oil a pain. More than likely there will be a mess to clean up. The push lock hydraulic hoses are a pain in the ass to have made at a local hose shop.
