Hi Guys:
Now I know some of you are going to say "why didn't you get a repair shop to do it", however I have tried to rebuild my 605 box and run into some problems.
Firstly, there is a circlip deep in the bowels of the unit, much too deep for my circlip pliers. I need to get it out to get at a seal. Has anyone had any luck getting this little bugger out?
Secondly, the rebuild kit I purchased is not exactly the same as my 605 unit (but its close). The kit came with an exploded drawing of the box but it is slightly different to what I have. Can anyone direct me to a site, or have rebuild instructions including diagrams?
Thanks,

There were two different 605 boxes. Can't remember the years but one has ferrel fittings the other has o-rings. I don't know if there is any difference in the two as far as rebuild kits but this may be your problem. I know I didn't answer your question but it may have some affect on your situation.

Howdy!
I don't recall any clips down in the unit.
Are you talkin' about the round top piece?
If so, there is a little hole on the outside of the ring area. Use it to push the snap ring out and remove the top.

I'm guessin' you have already removed the screw in cover on the back of the unit and the sector shaft.???

You have to completely disassemble the box to rebuild it.
Most kits will have an extra "o-ring".

Maybe the boxes are different over there

You can get a rebuilt from auto zone and such for around $130.

Do they have autozones in Queensland, Australia?

Sorry about that, again I have said something dumb, because of not reading everything in front of me.

I think you are refering to the snap ring that goes in to hold the pitman shaft seal from blowing out under pressure. Most PS boxes have this snap ring and a pair of snap ring pliers with a long nose will work well on them.
Do your instructions show cutting off the two outside teeth on the 5/6/7 pitman shaft? Grinding the head thinner on the upper pitman adjusting screw?
Classic Chevy has a good article on modifying these boxes and I have used it to convert many boxes.

Any man that thinks he is too old to learn new things, probably always was....

Thanks Everyone for the replies.
John, the circlip is located in roughly the centre of the unit when it is vertical. I think Coley described it correctly (it holds the pitman shaft seal from blowing out under pressure).
Although I am located in Australia, the box came from the US so I know it originated from an American manufactured automobile.
One more bit of information is that the box has already been converted for my 57, it is just tired and in need of a rebuild.
If I can get my hand on some proper instructions and the correct tools (ie a long handled pair of circlip pliers) I will be in business.
Thanks again everyone.

Do you have any other specific questions? I have instructions that came with a seal kit, and out of a service manual. Frankly they are not all that detailed. The box is pretty simple to work on once you get those snap rings out.

Can you detail the differences between your box and the instruction sheet? Maybe these are related to the conversion.

The only differences between stock boxes that I'm aware of are the seats for the hose connections, early are inverted flare and later are o-ring.

I'm not able to scan or otherwise transmit the info I have for a couple of days, so if we can answer your questions maybe you could get going sooner.

Does anyone know the size of the allen wrench needed to take the end cap off? Also is there a seal in there that can be changed easily mine leaks from there. Is the end just a cover or does it hold other pieces in the box?

The allen wrench needed for the end cover is 3/16".
However it is an adjuster, it doesn't fasten the end cover.

The end cover is fastened to the housing with a round snap ring. There is a hole in the housing where you can insert a round rod and disengage the snap ring to where it will spiral out. The end cover holds the sector gear in place.

There is an o-ring on the end cover and it is the usual source of leaks.
