Week TechVideo, 2008 #40 - 8860 Auto Chassis

This week some nostalgia... A video from 8860 Auto Chassis, released in 1980.
My first TECHNIC set and still one of my favorites.

Easily can imagine the satisfaction of someone who get this set nowadays, like vonsmallhausenPL.

80 or maybe it was 81? Best Christmas ever.

8860 was really released in 1980.

See for instance this, but there are several other sources confirming it.

Maybe you got it in 1981 as I did.
This set was sold for several years, which is not the case nowadays anymore, where the sets are sold for only one or two years.

I finally got this kit last year, after seeing it for the first time nearly 25 years ago! :) an older neighbor had it, and I thought it was the most amazing thing at the time..

However, now that I have it, although I can see how incredible it is, by those early standards, it wasn't quite as good as I'd hoped.

The steering for example, tends to stick a bit, with the old-style 'squarish' bushes. replacing them with modern rounded-edge ones makes it work better.

The gearbox only has 2 gears, and isn't the easiest to change gears.

I recently got the 856 Bulldozer, and the lift/tipping mechanism is much more amazing to operate, although it's very small sitting next to the car chassis!

So, Rohan, you're saying this thing has a working gearbox! If so i will get the instructions for this and build the gearbox! *drool-drool-slobber-slobber*

This set has indeed a not synchronized 3 speed gearbox.

I presents a linear and very early design, which has some small problems.
Namely the handle tends to move out of place in the main axle where it connects and gear teeth touch each other when changing gear speed.

The 8865 Test Car has a gearbox based on the same technique: you may see it there too.

You can also find excellent pictures of the 8860's workings (gearbox included) at Technicopedia.

TechnicBRICKs said...

This made me remember that 8860 instructions lead to build a 2 speed gearbox, but the 3 gear version can be easily achieved, by not assembling a 2x3 plate.

Its purpose, s for a motorized version of the car.

You may find the correspondent instructions here.

Also note the change in suspension!

check out the image you linked to - note that on the front cover, it has 'homestyle' springs on axles, compared with the self-contained ones that we are used to.

look at this page of the instructions too,
and note that it's different from the preceding, and following steps, in that it also doesn't have the self-contained suspension part!

When I was younger, and only had a few technic kits, and none with suspension, I used to make my own with a rubber band, 2 axle connector, and a grey peg... worked great!


TechnicBRICKs said...

In fact there seem to have been some variations to 8860 suspension, despite I've never seen another version than those with self-contained suspension parts.

Maybe it was just a preliminary design not so much efficient.

Read some comments I made about this, earlier at EuroBricks (post here).

I got one second hand, maybe 85-6, I must be a few years younger! It was still one of my favourite sets! or was that 8851?

Yes the third gear was for motorisation only..
I never could see the point of the grey box though! any ideas??

TechnicBRICKs said...

Always thought the front gray box, was there only for aesthetically purposes.

Somehow it also resembles a frontal car trunk.

Parax said...

yes I came to that conclusion, but if there is no shell on the car why just a box that doesn't open?
perhaps originally there were intentions for a second motor for steering that could be enclosed, or maybe a different design of battery box? (like the earlier boxes?)

Parax said...

oops, ignor that comment there was a steering motor mod wasn't there.. its on the instructions lol... bad memory..

TechnicBRICKs said...

Exactly that!
There was instructions included, to modify the main model and add a motor to drive the car and another for steering.
See it here.

Never though an old model, would generate this amount of comments.
It might have been a really good one!
In fact I believe it was big sell success for LEGO at those times.

TechnicBRICKs said...

Oops... we should have been writing at the same time...

Alex Campos said...

Wow, I never imagined LEGO would dare attempt making instructions to "RC-ise" such a big model using only two 4.5 V motors!

As for the grey box, I always imagined it to be something like a radiator, to get hot water from the rear engine, cool it with incoming air, and send it back to the engine (even if the cylinders have fins).
