Features are slewing superstructure, raising and grabbing arm and moving threads. Interesting pieces include a large turntable, 4 Technic thread hubsa mini Technic digger bucket, 2 Treads. The boom lifting mechanism is driven by a worm gear. And 8T gear is placed underneath it. It is then locked by thin liftarms. It’s excactly the same as thebut it does it in a different way. It is the only excavator that uses actual rubber threads rather than plastic ones that doesn’t work.
The low gearing for the boom and bucket makes this excavator able to lift something. The only con is that the 8T and worm screw combination has a lot of play. This has to be my favourite excavator.
Pictorial review: Excavator – LEGO Technic and Model Team – Eurobricks Forums
I really like the smooth bucket and arm movement, and the rubber threads are a nice bonus. Feel free to ask. I never 819 get that set,It never appealed to me very much. I have two of the excavator’s wich I thought were quite good.
If you want a good excavator you should try to build jurgen’s Zorex excavator. I remember this one, it’s the last Technic set I got before my mini dark-age As it turns out several parts were of different colours as I remembered rebuilding it from the B-model without all the spares left over from the A.
I have all four of these excavators and though I prefer due to the rather brilliant gearbox is still a very good model too, doing the same things at a smaller scale. Not a bad one to legoo in your collection by any means. You need to be a member in order to leave a comment. Sign up for a new account in our community.

The turntable is placed on top. And then the threads. This rack is mounted at the rear of the turntable, to support the gears.
It meshes with 841 20T bevel gear at the end of a 3 axle with an UJ.
Placed on the base. The digging arm is then attached to the grey liftarms.

A 24T gear is attached to the axle driving the boom lifting. An 16T gear is connected to the axle which powers the bucket tilting. A worm screw is combined with the 24T gear to slow down the boom movement. Lastly, a 20T DB gear is added to further reduce the bucket movement.
