Question for the 605 gang!

[jrhodus]

I just came in from my shop where I noticed a liquid puddling under my baby. :mad: I put it on my lift to get a closer look and this "oil" seems to be coming from the bottom of my 605 box. :eek: My question is: How hard will it be for me to change out the lower seal? Can someone offer instructions for a job such as this? This is a converted 605 box that was done by a friend of a friend.....whom I would rather not bother at this time as he has gotten on in years. ;) Any help will be greatly appreciated. My 55' is my main mode of transportation and I really need to make her well again. :)

Do you have the type of 605 conversion that uses the lower section from a stock box and the 605 over it?

It's not a terribly hard job but I think you'll have to pull the box from the car. This means you'll have to:
- pull the pitman arm
- disconnect the rag joint
- disconnect the hydraulic hoses
- pull the box from the car
- remove all the bolts holding the 605 and the stock lower housing

Then you'll have to take apart the box to the point where you get the sector gear out of the main housing. Once that's done you can pull the seal and replace it.

You should be able to get the seal at the auto supply. It's probably best to buy a seal kit for the box and replace them all.

If you can locate an online article on a home made 605 conversion, it will have photos on how to put it together. And of course taking it apart is just the opposite. 57Viper may have a scanned 605 article.

Rick, it does use the lower section from the original box. Thank you for your reply. I will see if I can locate the article you mentioned. If memory serves, it seems this conversion was done following the advise from just such an article. I figured I would replace everything that is replaceable when I open this thing up. Thanks for the suggestions. :tu
