555 torque converter follow up

Made a little rig to check torque converter endplay the best I could. Im confident in saying its .045 but couldnt find a spec in the manual. Thanks for your previous response Bern .025 - .050 max endplay put me just under the limit !

The potential crack in the drive plate looks good after further inspection

The TC is welded and the manual says the only maintenance other then a stall test is cleaning with a commercial torque converter cleaner or a paraffin base solvent so thats one of my next steps

My 555 unit number is 9D09B (9th day in April 1979 day shift)
Manual says an improved durability torque converter was incorporated into production @ Unit # 9E09. (Exactly 1 month after mine was built) they are interchangeable.

With everything on my plate and my machine work almost complete I feel this TC is good to go back in after cleaning

If i did have future problems would I be removing the trans from below to access the TC or splitting the tractor again ?

Can anyone recommend a rebuild kit for a Lucas CAV DPA ? Other then what comes in the kits and replacing the Veins is there anything else I should be looking at ?

I wouldn't bother trying to flush that converter unless the oil in the transmission was dirty or contaminated somehow. As for the end-play specs, that .025-.050" range was what I was able to glean from other manufacturers. You're right, Ford does not specify a number in their manual. .045" is getting up there though - you might wish to call a place that rebuilds them and ask their opinion.

OR, ask yourself a question: While it was running, was the transmission sluggish, or pretty responsive when you gave it fuel? If it was sluggish, you likely have either excessive clearance internally, or else a bad one-way clutch in the stator.

Think of a torque converter as two fans facing each other. The powered one, the engine, drives the non-powered one, the transmission. The farther apart they are (i.e. more internal end-play) the less efficient the power transfer is.

Thanks again Bern

I found a local 1 man shop that could take a look today. He felt it and said right away it was close to needing a rebuild

he showed me his shop and equipment to open it with a lathe, another machine that holds the torque converter on an angle and rotates it while an attached welder re seals it and another one for balancing.

I could have spent all day in there !

That's cool... I started my career in a transmission shop they drilled a hole in the side and stuck a steam jenny in the drive hub and let it run for quite awhile. Then they would weld up the hole, I spec they did thousands that way. I am not advocating that just saying that's the way they done it...

Either lock up converters stopped that practice are they became more available overnight at a good price. I use to stock a few, other than lock ups they were inexpensive insurance...
