BriGuy, your picture of the agitators on your V2 appears to show them out of time with one another. The bristles of one agitator should never touch those on an adjacent one. Enmeshed as yours appear to be causes excessive resistance in the apparatus.
The V2/Dual V design has two versions. Call them an early and a late, there is the version used prior to 06/03 and those made on or after 06/03. Your V2 is likely an early version. Check your serial number for date of manufacture to be sure.
The agitators for the V2/Dual V come in rights and lefts. The machine has two of each. The right and left position isn't definitive as to where they go in the machine; evidently just for identification. Color coding would've been better.
On the early machine, the agitators work in diagonally opposed pairs. Viewing the floor nozzle from the operator's position behind the handle, the agitator at the left front should be marked R; the one in the right front corner should be marked L. The agitator in the left rear (row closest to operator) should be marked L; the one at the right rear should be marked R. They should be positioned in such a way as to allow for now interference of bristles.
Just for information's sake, the 06/03 and later machines have both L's in the back row (as viewed from the operator's position behind the handle of the machine) and both R's in the front row. The agitators marked R are the same part for both early and late versions. The agitators marked L are different; early and late versions each take a different L agitator. There are many other parts differences in the floor nozzle between the early and late versions.
When diagnosing an out-of-time issue with the agitators on these machines, it could be a problem beyond incorrectly installed parts. To wit, it could result from a problem in the gear train that drives the agitators. The steel shafts that turn the agitators are set into plastic gears. Sometimes the bonding between the shaft and the gear fails. In this case, the shaft will be loose on the gear resulting in incorrect timing of the agitators, or failure to rotate at all, the "off pair" just kind of free-wheeling driven by interference with the other set of agitators.
The gear train and motor come as an assembly, but clever people can take the gear parts off and repair them. I've done it several times with success. Basically, the repair is to clean everything, then epoxy the loose shaft back in the bad gear. This must be done carefully to maintain concentricity of the shaft in the gear. Also be prepared to do some wizardry on the plastic gear housing; the screw holes can shear off and you have to re-engineer the fasteners.
Here's a picture of a Dual V early design that I believe shows correct agitator positions. Note how the bristles are aligned to rotate without touching.
