davidmull Posted March 10, 2011 Posted March 10, 2011 Has anyone added power functions set to this,I have my 8049 back in it's box but I'm thinking of rebuilding and adding my pf set from my 8265,I'd like to do it as iv never seen a compressor in use in technic as I never got the ultimate 8868 all them years back,it might also give an insight to how the new unimog will work,my question is does both pf and 8049 work well together and because were starting to see pneumatics return is this new simple compressor set up efficient?also we have never seen the blue air tank used in many old sets how come?I hope 8110 will have air tanks too!

DLuders Posted March 10, 2011 Posted March 10, 2011 I suppose that it's possible to motorize the 8049 Tractor with Log Loader set. However, there's not a lot of room for the Power Functions components. Do you have something in mind like SzokoliBence's "Lego Technic 8049 Tractor with Compressor"? http://www.youtube.com/watch?v=JibSCxihuMM Quote

Anio Posted March 10, 2011 Posted March 10, 2011 The model shown in the video may have some problems : the video is speeded up (x2 or x3) and the moves are still very slow. O_o Quote
davidmull Posted March 10, 2011 Author Posted March 10, 2011 (edited) 8049 includes instructions and some extra parts for a motorized compressor. Yes ur right it does come with instructions to ad power functions,And it comes with the small pump too,did u not know this luder? Edited March 10, 2011 by davidmull Quote
davidmull Posted March 10, 2011 Author Posted March 10, 2011 This is it with pf and it looks quiet slow but cool too,I wonder is the 8110 going to be like this because I hope not , this is a clear example why pneumatics are just not accurate, http://m.youtube.com/index?desktop_uri=%2F&gl=IE#/watch?client=mv-google&v=mYStKR4z1-U Quote
rjk1977 Posted March 10, 2011 Posted March 10, 2011 I just bought one a week ago (for sale 50 euro) , i am going to install the PF this weekend. I hope its good with the PF Quote
DLuders Posted March 10, 2011 Posted March 10, 2011 @ davidmull: No, I did not know that the 8049's Building Instructions showed how to add Power Functions, but I do now! Brickset confirms that one can "Add compressor function by purchasing 8293 LEGO Power Functions Motor Set! 2 models in 1: rebuilds into a log handler!" Here is another about the motorized 8049. Jcbarros71 wrote that it shows a "LEGO Technic 8049 Tractor with Log Loader, with one M motor added to pump the air for pneumatics (as proposed on the 8049 booklet), and a few minor MODs, like rear lights on Tractor and Trailer, rubber axle connector added to grabber ans trailer support, and the Black Bar 9 x 13 Grill was attached to the battery box with no extra parts added (I really don't understand why LEGO took off the Black Bar Grill when they added the battery box on the motorized version. See LEGO8049 instructions book)." In the shown below, ssugawara1955 shows his DRIVEABLE 8049 set: Quote
davidmull Posted March 10, 2011 Author Posted March 10, 2011 I'll rebuild it with pf and see how it goes,can Lego not bring out some sort of valve to limit airflow to make pneumatics smoother,also let's hope the 8110 works better and has some new pneumatic parts to cure this! Quote
Aqualize Posted March 10, 2011 Posted March 10, 2011 As I remembered it (but lets see when folks here builds the PF-added version) the pneumatic pump didn't do its full stroke length. I think the 8868 Airtech clawrig utilized the full length. I CAN be wrong about that. But if it is true it can explain why the 8049 doesn't have so much airflow. Btw I think the forest trailer is so wrong so I built my own (have I posted about this earlier on this forum?) It didn't turn out to be a nice and polished MOC, I only modified the tractor and the crane and built a better trailer (proportion-wise) (shows the drive of the trailer pushing the tractor). Read the description for info about all changes.http://aqualize.se/lego/forest%20trailer/ <-- a few pictures. For precision control I think (air) pneumatic are inferior to LAs. But when raw power is required the pneumatics are called for. Quote
Anio Posted March 10, 2011 Posted March 10, 2011 Hey, my 8049 with compressor worked perfectly (fast and smooth). And I din't change anything compared to the building instruction. Quote
davidmull Posted March 15, 2011 Author Posted March 15, 2011 Iv just added the PF set to 8049 and it works great,the little compressor is a great idea and fairly smooth too,makes me look forward to 8110 unimog even more now :) Quote
Out of Sight Posted March 16, 2011 Posted March 16, 2011 Just wondering if the Technic compressor comes with pressure valve? I mean how will you know how much pressure is in the tank, and to not overpressure it sorry guys I'm a total noob when it comes to pneumatics...which is why I need the upcoming Mog, just to get some know-how on pneumatics. However I agree that some people manage to operate their pneumatics pretty smoothly due more to the fact that they have a good 'feel', I guess it takes practice huh? Quote
DLuders Posted March 16, 2011 Posted March 16, 2011 @ Out of Sight: Maybe you should build a Pneumatic Limit Switch to regulate the pressure, like the one by Larry Pieniazek: Quote
DarkShadow73 Posted March 20, 2011 Posted March 20, 2011 Its not bad, but you have to remove some of the trailer for the battery box. A bit off topic but too bad they couldn't motorize the 8069 Backhoe Loader, I know its been done with pics here, but IMO all those motors detract from the aesthetically awesome looks of the stand-alone 8069, too bad it couldn't be done compactly underneath the model, but like its bigger cousin the 8455 Pneumatic Backhoe there's just no room for any extra components not too mess with the looks. The 8069 really is a much better value than the 8049 was last year. I just bought one a week ago (for sale 50 euro) , i am going to install the PF this weekend. I hope its good with the PF Quote

AndroTech Posted March 20, 2011 Posted March 20, 2011 (edited) Actually, 8069 came with four new mini LAs. Edited March 20, 2011 by Povratnik Quote

AndroTech Posted March 20, 2011 Posted March 20, 2011 True it did but I hate them nobs u have to turn by hand tho. Those nobs, are indeed the real essence of the Lego Technic. Quote
DarkShadow73 Posted March 20, 2011 Posted March 20, 2011 @davidmull - true on that, pneumatics are a lot of fun, but 8049 was such a ho-hum model and even when motorized you had to move the valves really slowly otherwise or the boom raised up or the jaws opened way too fast. I personally think the 8069 is a lot of fun to play with and was surprised at it being a 1st half model since it has so much going for it and is big. True it has only gear knobs and too bad there isn't pneumatics, but really the pneumatics in the 8049 were pretty simplified and it was a really bland, boring model. I modified the B model of the 8049 which I thought was a lot more fun into a telehandler and my 2nd one into a lift truck, basically a telehandler w/ the forks that I installed a platform that raised up. I keep wanting to get my fiancee to take pics of both of them, but keep forgetting to do so. Also, I replaced the gray wheels with the same size black wheels from the 8053 set since the B model doesn't use them as I modified the harbour crane's 'feet' without the wheels. I dont agree, 8069 came with nothing , 8049 has pneumatics Quote
davidmull Posted March 23, 2011 Author Posted March 23, 2011 Seeing this set come with the extra parts to make a compressor was a huge bonus to me and others ,even tho on this forum people don't seem as excited as me,this is the only other set rather than 8868 air tech claw to come with the small compressor cylinder so I think it deserves a big welcome because of all the love for the 1992 air tech claw 8868. Here is the review as I think this set is a must buy for that small pump alone and is a very underrated set :) http://technicbricks.blogspot.com/2009/12/tbs-techreview-08-8049-tractor-with-log_03.html Quote
DarkShadow73 Posted March 24, 2011 Posted March 24, 2011 Would love to get my hands on an 8868 Air Tech Claw Rig for a decent price MISB...not possible anymore though...

Mortymore Posted March 24, 2011 Posted March 24, 2011 davidmull, don't be sad because you're not alone. I love the 8049. It was my first and only set with pneumatics, and it started pumping my heart as soon as I saw it. I am tempted now and then, to by another 8049 set for the pneumatics, but the shipping costs always kept me to do so. I was so excited with my new pneumatics system that I also motorized the 8049 B-model. I motorized also the Hauler 8264, but replaced the linear actuator by a motorized pneumatic piston. Now, I hardly can´t wait for the Unimog 8110... mostly to grab those pneumatics. Cumps Quote

DarkShadow73 Posted March 27, 2011 Posted March 27, 2011 @Mortymore - I really didn't mean to totally bash the 8049, but I think I like the B Model better in terms of looks, and it made for an awesome convert to a mid-sized telehandler/man lift. Love your vid on the motorization of the pneumatics on it, I'm not great at MOC's, but would like to motorize my telehandler/man lift version I modded, but I haven't figured a way to do it. I have an always will be a fan of pneumatics over linear actuators, the 8455 Pneumatic Loader is unbelievable, imagine if somebody could motorize all 10 of those cylinders, it would be a the best Technic set ever. davidmull, don't be sad because you're not alone.
