Large Dome Cover w/Gasket X9034-C
$61.95
The Large Dome Cover w/Gasket (part# X9034-C) is a genuine Tacony OEM replacement part from the recovery and solution tank assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the large recovery dome cover supplied complete with its sealing gasket.
What the Large Dome Cover w/Gasket does
The Large Dome Cover closes the main recovery tank opening and, with its bonded gasket, forms the primary vacuum seal on the dirty-water side. All the lift the vacuum motor generates is held by this joint. It is also the access point crews use to empty and rinse the tank, so it is opened and closed several times a day.
When to replace the Large Dome Cover w/Gasket (X9034-C)
Replace it when the gasket has taken a permanent set, gone hard, or torn, or when the cover itself is cracked or distorted. The tell is weak recovery that is unaffected by clearing the wand and hose: if the dome hisses when the machine is running, the seal has gone.
Large Dome Cover X9034-C — fitment and installation notes
Supplied as cover and gasket together, which is the sensible way to buy it — replacing a hardened gasket on a distorted cover rarely restores full vacuum. Seat it square and clamp evenly so the gasket compresses uniformly all the way round. Tacony builds the Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared Tacony component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
