I finally found this set at a reasonable price and purchased it, and have now completed building.

The biggest flaw to me was the rear wheels, so  I modified it with two differentials and dual wheels on the rear. I also replaced the pins with stop bushes at the base of the crane and moved the clutch gear.

I find it tries to turn the crane when operating the crane booms, but havent yet checked any further as to wether something is binding.

Currently working on the alternate model pickup, but with 4wd and powered with PF remote control.

Thansk! I havent built mine yet, but it's nice to see there are ways to improve the set.

Hello everyone,

just finished my 8258 Truck with all MOD's from designer-han's site.

I had the problem that the crane always rotated.
After two days checking and rechecking I found out I placed the lower 16 tooth gear with clutch upside down.

While checking the building instructions I found out that the two black Technic Axle Joiner Perpendicular are not leftovers.
Check building instructions book three, picture 115 or 116 and you'll know where they belong.

Happy building!
Ralph

so does it really matter if the clutch gear is upside down? quite hard to believe. i thought it should work either way.

Hi Enilder,

I guess you have the white 24 gear clutch in mind Posted Image.

I'm talking about the 16 tooth gear with clutch Posted Image.

If this is upside down the transmission driving ring Posted Image can't go in the
16 tooth gear with clutch and you don't have an idle.

That's the reason why my crane didn't stop rotating.

The only issue I have with this set is having some functions opperated via a knob right by or connected directly to the function they was operating (outriggers, boom extention and winch) and the crane arm being a bit weak. Apart from that I didn't have any unwanted turning of the crane or steering misalignment or walking axles or any gears breaking or anything. The clutches in the white gears and LAs would always slip before any damage could be done.

Was thinking of modding my 8258 to motorise everything and include pneumatics. I have it all designed, mechanicle concepts test built and the whole thing ready to build but after recently seeing a real one doing it's thing at work I got bored of modding the 8258. I'm now more interested in designing my own, better version without using more than 1800 pieces rather than modify somebody elses design.

i am an idiot. sorry. you are right, i was thinking of that white gear. i never knew that the dark grey one is also called clutch. thank you for clarification. that 16 tooth gear has different sides so you are right on that as well.

even if you have it correctly, the crane still rotates (about 5 degrees) due to play in gears but i guess yours was rotating fully. i've asked on this forum about that "slight" rotation whenever gears were engaged for the crane. it appears to be that it's inevitable.

After 15 min in the 0-position really NO visible rotation. I'm surprised myself.

... :sceptic:

good for you...sucks for me...

i even took it apart to see where this "gear play" is coming from but i couldn't find any. it occurs when you lift or lower crane arm(s). everything is tight so that's what i figured and blakbird noticed the same thing.

Exactly.

There is a little play, because there is only 4 dog-clutchs in the dark gray clutch.

I don't think that is where the play is coming from as the drive to the turntable uses a worm gear after its respective dark grey clutch (or sychromesh gear as I like to call it  :grin: ) meaning any rotation of the turntable and its drive mechanism will be stopped by that before it can turn the synchromesh gear. The play comes from the gears between the worm gear and the turntable and the frictionless pin used to hold the 24t gear to the turntable. This play is evident in almost any drive train and pretty negligable if you ask me.

May be. Dunno.
Actually, we see some play when we use the 2 LA's.

hi all

i am almost at the end of the build for this truck and have encountered some missing pieces in my set.

wondering if this kind of thing has happened before and if anyone else has had the same problem?

very likely, you used wrong parts.

i thought i was missing pieces but i found it on the truck. if you backtrack it, you should be able to find it.

Missing some parts, however unlikely, is still possible.
I rember a story about a someone missing over 70pieces.....

Backtracking for the part is a good idea. And i do hope you'll find it.
If you still miss them, just write a complaint to Lego: they will sent you the missing part.

I have over 100 technic sets and only one of them had some missing parts so it is rare but it does happen. Thankfully Lego has excellent customer services. Contact them and they will send you your missing parts right away.

I bought 14 sets last year and there was one small part missing in one of them. CanĀ“t remember what part it was. Bush or pin I think. No biggie.

Yea I had a missing piece on my 8420 StreetBike set which is like 4yrs old and they sent me the replacement set after going through the customer service site.

Part arrived from Germany about a week and half later for free!

Thanks  :classic:

Still, if anyone has the exact weight of just the truck, I would be grateful.
