Paul B Technic

For those who have built this set up I have a question, when pushing it along the floor so that the wheels turn and the engine pistons move has anybody had the rod and gear behind the engine come off and stop the pistons moving? I had this over the weekend and it took me quite a while to find the problem, please see the photos below. What I found with mine: What it should look like: Parts removed to fix it:

I purchased 8069 on the weekend, built it in an afternoon. Seems like a good model but some of the functions don't seem to work as well as I was expecting. Paul

I really like these types of trucks and I have had some basic plans for quite a while but I have never really had the time to develop one to a stage I am happy with, this thread now has me more interested so I will be doing some more work on this. Paul

Very nice work with this, looks really good. Paul

Does anybody know of any good suppliers for older Technic sets? Paul

I have now found a local forum and Facebook group which have a few local members :)

Excellent topic, I had never done with with U-joints until 8070 so now I am learning all about them. I can see some of my MOC's where this information will be handy. Paul

Thank you for the replies, I might build it up over the weekend to test. I will post my results. Paul

Excellent review, I love the photos. This was one of my all time favourite sets for quite a long time. Paul

I don't have that model myself so I can't give any "first hand" advice but I would be checking the gearing as it sounds like it is jamming for some reason, any chance you could upload a photo or video so we can see what I happening? Paul

Very well done, I love the opening / lifting top feature. Paul

Amazing level of detail in this, very well done. Paul

Some very cool trucks in that clip. Paul

Sounds like a good challenge, I quite like cranes and think they work well in Technic. I can't wait to see what ideas people come up with. Paul

I was thinking last night about how strong Lego is and what sort of loads (physical and rotational) something like a Lego Technic engine could handle. For something like the standard engine below what sort of RPM's do you think it could handle and what parts would break first? I might build up one and run something like an electric drill just to see, has anybody done this before? Paul

Really good work with this, looking really good. Paul

Thank you, I am glad you like it. Paul

I can report all fixed now, one of the gears was not aligned right, all ok now. Paul

Tonight I have made some changes to 8070, now as the hood open it also runs the engine. Look at the video and photos below to see how I did it. I can still easily change it to just open the hood and I can also get it to turn turn the rear wheels. http://www.youtube.com/watch?v=EdgcfjMJWzk Paul

Does anybody have a Ldraw file for this set? Paul

I am telling more and more people about it as I go on, I post some of my photos on FACEBOOK so anybody I know on that can see and knows. Paul

While building this did anybody find they were short one blue slotted pin? I was but lucky I had some spares in my parts bin I could use. Paul

This looks really good, very much like the original :) Paul

That looks very cool, thanks for sharing. Paul

These are all really amazing, very well done. Paul
