Not sure where else you can get these, but I got one of these from skinning the large shredder trash between the final two bosses of Motherlode on Mythic difficulty. I've tried farming it off shredders in the open world, but have yet to find any other than the first one.
I was at 127 engineering and didn't yet have the recipe, so you can definitely get at least some of the parts for the mount before the schematic.

Just had 1 drop off Шеф Разданк

I've had one drop from the final boss of MOTHERLODE and I got one from skingineering one of the big shredder mobs inside the instance.

I guess the optimal way to farm these is for sure to let all those shredders get activated and cross your fingers.

Engineered off an Azerite Extractor just past the first boss, 126+45 engineering (Mythic difficulty)

Update, I engineered a mech between the third and last boss and got another one, same run. This is my second run this week so no loot from bosses, but still able to engineer the mobs and loot these.

Update 2: I now have 6 of these and it seems like a 33.33% chance to drop from engineering the Mechs and Azreite extractors

Any information on whether or not Mythic difficulty is required? Was curious if Heroic would give it also.

Finally finished building a Mecha-Mogul-MK2 today.

Total number of runs : 24

Reagent	Number salvaged	Percentage salvaged
Закаленная в азерите броневая пластина	95	50.8%
Прочный стабилизатор	72	38.5%
Сгоревший электрический сервопривод	20	10.6%

Each run included 4 Механомиротворец, 1 Экстрактор азерита & 6 Боевая машина Торговой компании - when possible looting 4 War Machines with the potion buff but from my experience this did not increase the drop percentage of the Servomotors.
The Peacekeepers do drop Blast-Fired Electric Servomotors but at a really low rate.

Here is my comprehensive guide on how to farm this as of November, 2018:

You will need to farm the following items:
------------------------------------------------------------
- Platinum Ore x 50 (Mining or the AH)
- Storm Silver Ore x 100 (Mining or the AH)
- Expulsom x 20 (Scrapper)
- Azerite Forged Protection Plating x 20 (MOTHERLODE-Mythic, not M+, harvest defeated mechs)
- Crush Resistant Stabilizer x 20 (MOTHERLODE-Mythic, not M+, harvest defeated mechs)
- Blast-Fired Electric Servomotor (MOTHERLODE-Mythic, not M+, harvest defeated mechs, RARE)
- Barely Stable Azerite Reactor (Have high BFA engineering, purchase for 30,000g from Doctor Boom inside MOTHERLODE)
- Mecha-Mogul Mk1 Remote Activation Device (MOTHERLODE-Mythic, not M+, drops from Mogul Razdunk, must have max BFA engineering + wearing fully unlocked engineering goggles + using Azerite Inspir-A-Geneering Elixir at time of kill)
- Mecha-Mogul Mk2 Recipe (MOTHERLODE-Mythic, including M+, drops from Mogul Razdunk, must have BFA engineering any level)

Bonus Items Needed:
-------------------------------
- BFA Engineering Goggles, all traits unlocked (will boost your BFA engineering level)
- Azerite Inspir-A-Geneering Elixir, Unique, drops from Megaminds in MOTHERLODE at high engineering levels

Basic Instructions:
--------------------------
- Train BFA engineering and level to max ASAP
- Build your Goggles and unlock all traits (boosts your BFA Eng level more when equipped)
- Run THE MOTHERLODE on Mythic (normal mythic, not +) while wearing goggles
- Pull, kill, loot and harvest the mechs to collect Plating, Stabilizers and Servomotors. It seems higher BFA Eng level yields higher drop rates.
- (High Eng Required) Buy the Barely Stable Azerite Reactor from Dr. Boom for 30,000g
- (High Eng Required) Kill Megaminds to loot Azerite Inispir-A-Geneering Elixir
- (High Eng Required) Use the elixir before Mogul Razdunk dies (can be during fight) and loot the Mk1 Activation Device.
- After you get the Mk1 Activation device, elixirs should be used on the hill before Mogul Razdunk to boost harvest rates on those mechs
- Kill Mogul Razdunk on any Mythic difficulty (Mythic, M+) and loot the recipe (any BFA Eng Level)
- Craft the mount
- Go outside and get some sun (optional)

Notes:
---------
- Farming the Servomotors will take the longest, as they seem to drop at about 25% the rate of the other two blue items.
- The recipe itself does NOT require high engineering level to obtain, and unlike most items may be obtained on any Mythic or Mythic+ difficulty.
- Always let the Mech Jockeys mount up, and request early on that your fellow dungeoneers do the same. If they are stunned or prevented from their first attempt to mount up, they may not try again, wasting a precious mech kill that run.
- Pull as many mechs as you can in a run, even if you have to pull an extra pack or two (Azerite Extractors come to mind). However, work with your group to make sure you're not pissing them off.
- I advise you create your own M0 runs and only invite non engineers to minimize competition. Some runs may only yield 1 or 2 blue mats even if you harvest all the mechs, so this is key.
- After you have obtained the Activation Remote using the Elixirs, they are best used on the hill before the final boss. If you are smart, you can harvest all 6 mechs on that hill with one elixir if you wait to harvest them till they're all dead.

For all you engineers out there wanting to farm the mats for the mount. I managed to loot 2 of each of the Прочный стабилизатор, Сгоревший электрический сервопривод, and Закаленная в азерите броневая пластина from Шеф Разданк on Heroic difficulty ЗОЛОТАЯ ЖИЛА!!! through the dungeon finder. I also managed to loot a Устройство управления "Шефовозкой-1" off of him in the same run. Granted its not the quickest way to farm the parts, but its probably the easiest. I have not confirmed if this is farmable or just lootable once per day like other heroics. I also do not have the schematic for the mount so I can confirm it is not needed to loot these items off of Шеф Разданк.

i just ran through this in normal mode to see how the dungeon is. this also drops in normal.

As of 9.1 mech jockeys are not getting in the mechs. Submit your bug reports, people!
