Sat in the shop contemplating...

I’ve got a rock lobster transfer box as a side project, just in case the standard-ish (diffs changed) gearing doesn’t work out for me in the buggy project...

I’ve just ordered a JimnyBits conversion spacer -



So that - in theory - I can fit a standard Jimny rear propshaft...

And I’m in the process of buying a Jimny standard transfer box to put on the bench and attach standard mounting brackets so that I can have a reference / pattern...

So, my question... has anyone ever fitted an SJ / rocklobster transfer box in this way and used readily available standard Jimny propshafts, rather than having to rely on old / obsolete SJ parts...?

Hence wanting the standard transfer box to experiment in getting the SJ transfer box to sit in the same place as the Jimny transfer box...

Is that buggy finished yet?...

Based on recent experience, using a prop shaft company to adjust and then balance props was quite competitive to buying and refurbishing SJ props, and they are then the correct length rather than "close"

Thanks Martin...

What props did you have adjusted? The standard Jimny ones?

SJ ones.

Although the mounts were "designed" for SJ props, they still needed quite a bit of adjustment for a proper fit.

The mounts on mine are probably not representative of the current designs. They were a very early prototype from ORA in probably 2007 so I expect there was more "tuning" work to be done in terms of positioning.

I got a despatch email this morning from JimnyBits to say the above conversion spacer had been despatched...

Re-reading the item description, I noticed it said "A machined adapter that allows the use of a jimny rear propshaft with our SJ / Samurai transfer box conversion kit"... So I opened a support ticket asking what props their kit (which is currently listed on their store) used as front propshafts...

I quickly got an email back saying that their kit uses standard props front and rear... so I'm heading in the right direction! :woohoo:

Hopefully they'll bring their kit back to market soon, as fitting an SJ box using old / obolete parts is a pain, and probably puts a lot of people off...

I know it could be argued that the standard Jimny prop may not be quite as strong as an SJ one, but they are plentiful supply! ;)

Interesting installation video of a spined transfer box mount (found on an item on the JimnyBits store) -



I've got a spine an order too.. from "redacted" ;)

Looks an alright design
But the spine needs a step in it :ohmy:
When he slides the longer mount behind,it pulls the spine away from a flush fit
You can see at 10:28 possible oil leakage

Well spotted, I thought that was a little strange too?...

Useful inspiration though :)

That’s the sort of thing I want (to make)...

But it’s 400 Euros with the conversion / prop spacer(s) - www.hm4x4.com/en/suzuki-jimny-installation-kit-t-case

Plus shipping....
