[MOC] GAZ-66 Drilling Machine

[[MOC] GAZ-66 Drilling Machine]

After a number of months after construction, I share my first full-fledged MOC

Scale - 1:11
Weight: 3300 g
Length: 57 cm, witdh: 22 cm, height: 23 cm

Functions:
All-wheel drive with interaxle and cross-axle differentials, fake engine V8 (copy of ZMZ-66-06)

Steering by HOG (in back) or sttering wheel in the cabin

Retractable outriggers by PF L-motor (1), transfer case and 2 mini actuators. Turn on/off by switch on operator's wokstation

Arm raising by PF L-motor (1), transfer case and L actuator. Turn on/off by switch on operator's wokstation

Drill raising by pneumo (compressor by PF L-motor (2)). Turn on/off by switch on operator's wokstation

Drill rotation by PF L-motor (2), transfer case and sliding worm gear. Turn on/off by switch on operator's wokstation

Opening doors, hood (in the cabin)

Cab tipping

4-speed gearbox with H-scheme (shifter in the cabin)

Suspension for all wheels

quietly moving on...

I hope the black axles above gearbox will provide H gearshift scheme (more precisely, they will not be allowed to turn on two gears at once)

Как насчет того, чтобы положить резинку лего на нижнюю дистанцию, чтобы она действовала как прокладка / шайба?

Brilliant! In the evening I will try

So

I did not know, but technic ball can fit well between two liftarms and It will have 2 degrees of freedom (more precisely even 3)

 

And everything would be great if not for the need for gaps (red lines on pic)

Действительно. И если вы настаиваете на сохранении 4-ступенчатой коробки передач, вы всегда можете просто установить переключающую защелку на оси для различных положений, это несложно сделать. Это может быть сложнее сделать, как оригинал, у которого ручка вращалась с помощью шарового шарнира ...

I think I have an idea how to make a shifter with ball-joint. But no morr 4 speeds

Now we're talking :) I built all my childhood models mostly out of 8880 parts, as that was my only big set at the time..

Yeah, Defender tires are almost the same, only 2mm wider. A studless version of the manual 4-speed gearbox is pretty easy to replicate, I just did that in my Willys Jeep alternate of the Defender, exactly inspired by 8880. However, I agree that it could be a good idea to modernize it, but I would suggest instead of adding more speeds, adding maybe a DNR selector and changing the manual shifting to sequential shifting, but not as in the Defender, and not with paddles, but with the gearstick as in Nico's Ford F150. That would be more interesting for me, I have never seen that in other cars.

That's also quite easy to do with the hubs used in the Defender by connecting a 2L liftarm to the hub.

Good luck!

Thanks!

I want the gear lever to swing, not slide

Such a shame the more recent suspension parts don't have an Ackermann angle or a decent CV joint.

Good luck, keep sharing :)

Thank you!)

Ackermann - a question to be solved. But angles of rotation will be very sad.

And unique gearbox shifter in original 8880 hrad enough to repeat

I have long wanted to make a replica 8880, but here is such a case...

I doubt that will do very close to the original. But at least it is possible to withstand the scale (tires from Defender are great, the width and length will probably be 1 stud more).
