620 disk brake conversion

Post by bromigo »

Hi all

im looking into changing my 620 ute from drum brake to disk brake.
Unfortunatly it is kingpin at the moment and i havnt had much success finding balljoints for it from another 620.
Im currently looking at modifiying some 5stud disks to fit as a last resort.

Does anyone have any further ideas or possibilities??
(Wheel size and stud pattern doesnt matter)

If it helps someone did a disc conversion on my 74' 620 at some point, its still the kingpin setup and factory arms,

as far as I can the the brake setup looks like factory bolt in parts, from what I have no idea thou. Ill take some pics in the next day or two of the setup and post them you might be
able to work out the what its from
vr6 idea still siting there, much research in the plumbing before I commit.

Easiest way is to find late 620 ball jointed arms. Then d21 navara hubs and stubs can be made to work.
They don't call me the man with the rubber arm for nothing you know.............

Thanks for all the replys guys

i was looking at bearing sizes last night on the skf website, when it dawned on me that the inside diameter on r31/z31 bearings are quite close.
It looks like the outer hub bearing inside diameter is 1mm smaller than a 620 outer bearing. (19mm vs 20mm)
wishing i didnt get rid of my old r31 hubs now

can anyone give me the stub size/length for a r31 or equivalent??
or hook me up with a hub to try out?
