XX4 steering bellcrank

[matthewjtovey]

Hi,

Was running my xx4 at the weekend and the bellcrank arm slipped on an impact. Its started to flatten a few of the splines. Is it a complete write off or can it be salvaged? I've seen how people use longer bolts and washers to stop it happening but saw them too late!

If I need a new one where can I get one from? Any other tips to stop it happening?

Thanks for your help.

LOSA1550 I think is still available.
I was lucky enough a few years back to get a full alloy bellcrank setup, but prior to that had ran the drive pin mod. Essentially you drill from the top down and insert a steel pin (similar to the ones used on the rear axles which drive the wheels), this plus a smidge of superglue helps stop the arm slipping on the splines

Thanks for the info. Will have a good look for the parts and at that mod.

Incidentally, where did you get the alloy setup from?

Thanks

If you really can't find a replacement, might it be an option to 3D print the parts and use a hex mounting instead of a spline system? There are surprisingly strong materials that might be strong enough (though it would be practical to add a little flesh just to be safe), and looking at the size of the part it wouldn't cost a fortune either.

PS: Also, could it be worth looking into the 22-4's steering bellcranks despite the fact there might be fit issues with metric parts on non-metric car...

That's interesting about 3D printing, that would never have crossed my mind to do that!

I did wonder about the 22-4 or other losi belcranks, has anyone tried it? And got it to work more specifically!

The alloy ones I have came from the USA, advertised as a street weapon item. I bought the last 2 available and fitted one with just a very minor modification.

Sorry but the spare one isn't for sale even if you chuck in your Grandma, 10% of the Brinx Matt bootie and a gallon of Ardmore single malt
