727 Help Please

71 Demon 528:
The valve body is back at Turbo action for inspection. The pump has been swapped out with a set that has a tighter thrust clearance. .0026~ and the clutch assemblies and stator support are at the local builder to verify clearance and function. (they are air checking okay for me) but, I'm on my first build.

The geartrain clearance seems on the loose side .028~ so I have ordered the Sonnax thrust washer shim kit @.010. My question to the builders is the geartrain clearance. The Tom Hand manual has the geartrain clearance listed from .010-.020 and down to .009. Any recommendations appreciated along with the input shaft end play that is preferred.

Thanks.

I’d follow the Tom Hand book on geartrain clearance. With thrust washers I’d try to stay on the .015-.020 side, but you can’t always get it 100% where you want it, hence why there’s a range.

Front pump to front drum end play id shoot for .015.
