Sunstrand shaft repair

[608KEB 824]

I need some help disassembling Sunstrand Hydro and reattach clip that holds each shaft together in center of transmission. Also what would a suggestion be as how to place transmission, so it's easy to work on

I'm not a expert on this... I hopefully can handle it with some advice. Thanks!

Need a service manual?

You can mount the transmission on an engine stand

If you can tell a closed-end wrench from a chainsaw you should be able to ratchet your way through this. 

 

When we did the full restoration project on my 1975 C160 Automatic I had to split the case. 

THESE PARTS ARE HEAVY.  

Please use appropriate cautions, tools, and PPE.  

 

I had the pump off for cleaning. Set it aside on the bench. 

The lower case is similar to the Wheelhorse Unidrive manual transmissions. Just less gears in there.  

All parts are readily available from one of us or our vendors. 

 

I like @squonk's engine stand idea.  

 

Be prepared for thorough cleaning outside and inside of everything anything those things and all things. 

After that clean it more.  

 

Here's the thread from that.  

 

 

 

 

 

Let me know what gaskets you need. I may have them here. 

 

@pfrederi @daveoman1966 and @953 nut were very helpful on that.

There is a HEAVY DUTY snap ring on each axle that retains them in the differential. You should mount the snap rings with the sharp edge toward the opposite axle when installing them. You would be well advised to replace Flex Top lock nuts on the differential bolts, McMaster-Carr is a good source if you don't have a good local source.

Engine stand mounting would be good for cleaning but once you are beyond that point it is a table top project because the housing needs to be split.

You can mount the trans in the engine stand and remove the hydro part. Then take out the 2 bolts holding the right side of the trans axle. it will hang there with no issues as it's not real heavy without the hydro parts. 

 

Or build a wooden box with a hole in the top so you can drop the left side axle through like a work stand.

I recently replace the axle bearings & seals on one. I use a table that the top two pieces separate on, this allows the tranny to be placed with the right hand side up.

With a hydro cleanliness is paramount. Clean the outside to a sparkle before you split it open.

 

@squonk @Achto  Does he have to take the pump off? don't I recall talk of being able to remove the right side if you just need to remove the differential.

 

@608KEB While you have it open check and clean the screen suction filter
