Product Details

The Genuine BMW 54-34-7-193-448 Convertible Top Hydraulic Pump is a factory replacement hydraulic motor assembly designed to raise and lower the power folding convertible top on BMW E85 Z4 roadster models. This OEM component transforms mechanical power into hydraulic energy, generating fluid pressure ranging from 300 to 450 PSI to operate the convertible top lift cylinders.

Key Features:

  • Genuine BMW factory replacement part for reliable convertible top operation
  • Complete hydraulic pump and motor assembly
  • Generates 300-450 PSI hydraulic pressure for smooth top operation
  • Direct replacement for failed or noisy hydraulic pumps
  • Mounted in trunk area with connections to fluid reservoir and lift cylinders
  • Supersedes part number 54347119633

Common Failure Symptoms:

  • Loud whining noise from worn pump vanes indicating impending failure
  • Slow or incomplete convertible top movement
  • Hydraulic fluid leaks from pump assembly
  • Complete failure to raise or lower convertible top

Professional installation is recommended as this repair requires bleeding air from the hydraulic pump and lines. For vehicles produced before January 2003, BMW also recommends inspecting and potentially replacing the left hinge (54347193449), right hinge (54347193450), and fastening set (54347186140) during pump replacement.

Easy site to order

Excellent Ordering Process, Thank You

ok so far

Very easy

Exactly what I expected

The product shipped right away and I received it about a week later. The part bolted up without any issues, I wished I had replaced the actuator at the same time. Very pleased with the product and delivery time. "I'll Be Back" - Arnold

The two machined metal parts were rolling around in a big box. Banging against each others machined metal spines. the part should have packing that would not collapse. foam peanuts, not plastic air puffs that collapse during shipping. Was surprised box packing tap did not fail. That would have resulted in missing parts at point of delivery.

East to find and purchase.

just ordered the part that was easy and quick

So far so good. I assume because the system allowed me to use the po box for shipping address that you can ship via USPS. Other carriers can not us po box but they are far more expensive. If there is a problem with that and you need physical address it is

Good supply and reasonable

Great items, good prices, fast shipping!

Thank you

quick easy checkout and the cheapest shipping by far

Good service

Good

First time customer and I'll be back! Great prices, and rediculously fast shipping. Ordered Sunday night, delivered Wednesday morning. Couldn't ask for better service.
