C303 disc brake conversion

[ravio]

Ciao everyone, i have seen in several threads some nice pics of disc brake conversion for the Volvo portal axles...
I am working on these great axles since i got a pair of them.
i don' t like so much drums and mine were in such bad condition that while changing them, the disc option became a must.

I would like to understand something more about it as my ideas are quite confused.

Looking on internet i have found quite immediately http://www.omt-offroad.com/ in germany, for sure a beautifull kit but what a price !!!!!

Arska-tehtaalta suggested me these 2 finnish places:

http://www.offroadtarvike.fi/etusivu/

http://www.offivaruste.com/catalog/index.php

both seems to do disc conversion.

A friend of mine here just machined the wheel hub, made the 6 holes and runs on this way...someone here used 2 extra flanges on the inner and outer side of the reduced hub to have a flat surface where to insert the new scews...i think it' s smart

Another guy i met on another forum machined the hub even smaller and welded a brand new biult 6 holes flange to it.... don' t know if it can become weaker in this way...

This is my first 4x4 and my first serious job! i am pretty sure i couldn' t find anything more complicated to do with my poor knowledge!
I' d just like to adopt the less invasive solution and do it in the best possible way...

I really like to have you opinion!

Ciao have a nice week end!!!

Hello Ravio,

that way to do it, like offroadtarvike or offivaruste is most common and simple + cheap way to get fe. toyota discs suite for C30X axles

those two extra pieces are "hightech" in my eyes, but it doesnt mean that they are bad or useless

I think there is no need to weld any extras, main point is get those surfaces straight against discs, and if you make holes and "worms" for 6 x 139,7 circle, you have many variations for rims

there is some picture from my project, i used toyo discs, wilwood and rover brakecalibers

Here's one topic from our ex-garage -> http://www.fjdc.org/bbs/viewtopic.php?t=373 . The Jeep is using Offivaruste disc brake kit.

so basically i can have the hubs machined here to the diameter of 173 mm , 6 new holes at a 139.7 mm and place new columns in those ones...do you have a straight hole or with a thread to screw columns in?
by looking at the link in ex garage forum in these 2 pictures it' s clear the process...

...it seems that there is a flange bolt on with the 2 extra screws...

i looked everywhere on offivarusta web site but i could not find any email !!!!!!!!!
do you know if they have one to email them for pricing?

Ciao enjoy your sunday!

6 holes with thread, and hexagon bolts from inside

those 2 smaller holes with threads are for "centering" the disc - and in picture ther is spacer bolted... (not needed there)

[ravio]

thank you!
i ve just received an email back fro offivaruste they say they have a new bolt on kit for a disc conversion on going that will be available in 2 - 3 weeks...i' ll wait to see it before doing anything!
Does anyone of you know anything about it?
