I've got a mountain board with rusted and siezed skate trucks, I can't turn toe-side at all which led to a couple of wipeouts! It's a MBS Core 90 from
a few years ago with what look like original MTB ATB skate trucks (not the pro ones available now). The nut is so corroded that a spanner was
stripping it, even after I used penetrating oil.
So... if I cut off the nut and remove the kingpin, are they standard parts I can order from a hardware store or do I need to replace the trucks?
I'm new to this forum and also to power kiting and landboarding. I've got myself a Libre Bora 4.5 sq.m and a Firebee 3.0 sq.m, plus a channel truck
ATB and a skate truck ATB. I've been out about 5 times with them, got a few short runs but need more practice. I've been ATBing my commute to improve
my feel for the board.
Loving it so far!!

welcome?
soooo...is this for real?
i never know anymore...jeffnyc - 21-4-2018 at 12:50 PM
This one's real I think. At least no duplicates on the boards here.
Sorry Canoepoloist, been having a bit of a spam problem - if you don't mind, just reply to let us know you're a human.
I would imagine the kingpin is replaceable. Maybe try contacting MBS and see if they'll send you just that part. A new skate truck is 30 bucks on the
MBS site. https://www.mbs.com/parts/
I'm sure others here know more inexpensive ways to do it.indigo_wolf - 21-4-2018 at 07:22 PM
Could be that MBS parts are not readily available in his particular part of the UK.
Or doesn't want to take the shipping burn for such a small item.
Check https://www.powerkiteshop.com they might have the part, but it might be too small to list on their website and they claim Free 24 hour shipping
on many of their products. Their phone number is 0121 544 9514 and their email is: info@powerkiteshop.com
According the MBS specs the king pin is 3/8" x 50 mm (Cromoly), they don't specify thread pitch but most kingpin threads
are fine (rather than coarse) so look for something with a thread pitch of about 24. If you aren't getting a direct MBS replacement, get a bolt that
has been hardened to Grade 8 or whatever the British equivalent is so that is doesn't shear on you while you are under power. Make sure that when you
reassemble things to either use a NyLock nut or a thread locker like Loctite Blue 242.
While you have the trucks apart, check the shoulders around the mounting holes for cracks or other damage. Also make sure there hasn't been any
gouging of the pivot cup which could also be causing turning problems.
Also make sure no damage has occurred to any of the bushings or other parts so that you can decide whether you are better off ordering multiple parts
or a replacement truck.
ATB,
Sam

Thanks Sam for the diagram, any idea what the bolt specs are?
I've already contacted MBS, they offered to throw in the bolts and nuts with an order of pivot cups and bushings. I've just had those delivered, but
no harm in having spares for 8 quid plus postage.
If the specs are well known I might head down to the hardware shop instead. But mine are too rusted to measure. indigo_wolf - 22-4-2018 at 04:43 PM
