Drive Systems

Dry Sump oil pumps, whether scavenge only pumps, or 3-5 stage pumps with pressure stage, are generally driven off the crankshaft, either by special ATI Dampers built for ARE with pump drives incorporated or with drive mandrel/Pulley assemblies bolted to front of c/s Damper/Pulley.
NOTE: From index on www.DrySump.com Home Page- Go to "Drives" and "Drive Gallery" for photos and information, located in index on left.

Scavenge Only Systems

Our Scavenge only systems as used on Chevrolet LS series Engines- ARE Stage 1 systems, are typically driven with serpentine belt drives, using our 8005 or 8007 (Y or F) body dampers, and 3020YM or 3020FM pump mount/tensioner assemblies.
NOTE: These systems use the stock internal pump to supply pressure

Stage II & III Pumps w/pressure stage

On our Stage II, III or IV systems we always use a HTD (High Torque Drive) Round tooth metric, or Gilmer (Square tooth) drive assembly.

Generally we design the drive system to run the pump at between 50-65% of crankshaft speed.

ARE LS Series Dry Sump Systems

The ARE "Direct to Block" mounting system is specially designed to allow both Y body corvette and F body systems to be driven with out HTD/ATI drive assembly. the belt tension is pre-determined and only needs to be adjusted slightly as block variations dictate, by using 2 precision flat washers between pump mount bracket, and black/ARE triangular plate. The belt should be "Taught" but never tight. Conversely- belt should not have too much slack. the slack side of belt should be able to twist approx. 45 DEG from flat.

This same type belt tensioning system is used to "fine tune" belt tension on our side mount pumps only with 4 washers or equal thickness under each pump mount "Leg."

Checking Oil Level in Tank

On ARE Dry Sump Tanks- oil level in operation should be at or just below slotted or screened baffle at upper portion of tank. after running remove cap and look at oil level through cap/filler hole. (See instructions on LS7 Install Instructions #7-8 Click Here)
NOTE: Make sure engine is run prior to checking as oil can find it's way back to pan via gravity, giving a wrong tank level reading. (within minutes)
