Randy, You may need to replace the Pulley For Flat Shaft (3884076), make sure the tracks isn't worn or make sure the cover is on properly.

(3 out of 5 stars) The Jury's still out
Reviewed By: Mike G. from Bedford, TX ()
Pros: Shipped Fast
Cons: Question if this part is correct
If they're certain that this IS the track for all Dolphin Diagnostics then I may have gotten defective tracks. I managed to install them but they seem Extremely tight, so much so that they walk off the brush rollers. I haven't put the unit back into the pool yet, just manually rolling the tracks though it doesn't look promising. The track seems a little too wide to fit in the brush roller's groove. The track creeps up onto the side of the roller and then works it's way off the roller. The knobs on the back of the stock track were completely different than this replacement track, I think that's part of the issue. I didn't see anything in the how-to involving using a pry bar to pry the rollers out to stretch the track far enough so I could get the side covers back on. I managed to do it but this makes me think all the bearings will be short lived on this unit now.

(5 out of 5 stars) Dolphin Diagnostic Drive Tracks
Reviewed By: Randy S. from Cincinnati, OH ()
Pros: Fit perfectly - fast shipping. Exactly as advertised.
Cons: Care needed to space track evenly around wheels for proper operation.
Replacement of the drive tracks brought our Dolphin Diagnostic back to operation. Old ones were worn smooth on the inside of the track
