Turbo 400 disassembly

[Kain]

The valves are sticking in valve body , the ones im pointing at

 

[Kain]

would the snap ring pooping out cause low pressure?

 

[Kain]

Bent up a little piece of strap I had
And got drums apart and seals at rock hard and the forward drum that had the snap ring off had a few small nicks in it

The CK5 trans guru…. @Greg Ducato
Heath has messed with them quite a bit as well… @folkenheath

 

[76zimmer]

Do you have a piston seal installation tool?
I've used a 2l bottle cut in a half circle shape before, works well

 

[Kain]

going to order this one

Pardon Our Interruption...

 

[Kain]

the book does not have torque specs at least i have not found them
what do you torque cener support bolt to?
I know the valve body is only 25 ft lbs
what do you torque the pump bolts to?

 

[Kain]

pump bolts 18 to 20 ft lbs

 

[nvrenuf]

Here you go, torque specs from an ATSG manual.

 

[Kain]

THANK YOU SO MUCH
when i pulled the center support bolt it was beyond tight

 

[folkenheath]

There is a trick where you slide the pump gears together, then lay them on a smooth surface. If you can drag the outer gear with the inner gear, supposedly they are not too worn. You also check the side clearance with feeler gauges.

You are supposed to preload the center support one direction when you torque the bolt, I forgot which direction, I'd have to look it up.

 

[Kain]

i have seen the pic with a screw driver and wratchet tightening it but looked weird

 

[Kain]

Parts are on order, was told by the mechanic here that i was on the right track for getting it going
and that was a relief

 

[Kain]

for those that have done this is there supposed to be a snap ring on the big band in the botum of the case?
just above it?

 

[Kain]

This one

 

[folkenheath]

Some trans have a center support to case "fretting" ring, but there should not be a snap ring against the rear band if that is where it was.

 

[Kain]

this one was on the rear band holding it into place

 

[Kain]

Don’t know the name of it but this one

 

[folkenheath]

I believe that was installed wrong, but it's been many years.

 

[Kain]

ok thanks man
