Preventive Maintenance Kit, Kinney KT150C

This kit has 21 different parts. Here is what you get :

Gaskets (5 total):

• Water Jacket Gasket (807645)

• Cylinder/Separator Gasket (807646)

• Valve Deck Cover Gasket (808476)

• Separator Cover Gasket (807644)

• Sight Glass Gasket (804193)

These gaskets seal the main parts of your pump. Without good gaskets, you get leaks. Leaks mean loss of vacuum.

Valves:

• 4 complete Discharge Valve Assemblies (066161)

The discharge valves are very important. They let gas leave the pump cylinder and stop it from flowing back in. Under normal use, the factory says you should replace these valves every year . When your pump is running properly, you should hear a sharp clicking sound. That clicking means the valves are working. No click? Time to check the valves.

Also, note that discharge valves are only sold as complete assemblies. You cannot buy just the spring or just the disc.

Bearings:

• 1 Ball Bearing – 30 mm (054104)

• 2 Sleeve Bearings (Races) – 1 ¼ (054111)

• 1 Bearing Locknut (054097)

• 2 External Retaining Rings (064036)

• 1 Bearing Backup Ring (801262)

These are the parts that let the shafts and pistons move smoothly. Worn bearings cause noise, vibration, and heat.

Seals and O-rings:

• 2 Buna O-rings, 69.4 x 3.53 mm (050232)

• 1 Buna O-ring, 53.57 x 3.53 mm (050227)

• 1 Stainless Steel Backup Ring (801237)

• 1 Shaft Seal Seat (065112)

• 1 Shaft Seal Seat, Cast Iron (065100)

Buna-N rubber is the right material for vacuum pumps. It resists oil and handles heat well. The stainless steel backup ring supports the seal and stops it from moving under pressure.

Other Parts:

• 1 V-Belt (051123)

• 1 Oil Sight Glass, Plexiglas (804192)

• 12 Hex Head Cap Screws (052469)

• 3 Centre Wall Locking Pins (802506)

• 3 Set Screws (802505)

The V-belt drives the pump. The sight glass lets you check the oil level. The screws and pins are the exact hardware you need. No running to the hardware store.
