Thank you for the order. I will ship today, ASAP.
hi juri got a few questions:
I'm curious how would one replace the pump head? would the hydraulic lines need to be drained prior to removal?
what is the real world results of higher pump head output? any potential damage to existing components due to higher pressure/more fluid?
when you say its a new model, is the electric motor itself new and different than the previous ones you were selling? or its the same motor?
To replace the stock pump head (Magneti Marelli) with these new pump heads (designed by Marzocchi) you need to add a 2 mm thick aluminum gasket between the mounting plate and the new pump head, because the centering lip and the shaft are 2 mm longer in Marzocchi models than the stock model (from Magneti Marelli). I am in the process of mass-producing those aluminum gaskets and will start offering those soon. Q1: what is the real world results of higher pump head output?
The "real world results" of a pump head with higher output volume is that the duration of pumping cycle needed to reach a certain pressure is shorter by a factor F
that equals the ratio of pump outputs (F
= 0.38 ml/rev : 0.24 ml/rev = 1.58). In other words, the pump head with larger output volume/revolution will achieve the required pressure 1.58 times faster. Q2: any potential damage to existing components due to higher pressure/more fluid?
The pump head does not generate higher pressure, it simply allows to reach the set point operational pressure faster and there is no potential damage to other components of F1 hydraulic system. This is because hydraulic fluid pressure inside pressure accumulator is measured continuously by a dedicated pressure sensor connected to TCU. When hydraulic fluid pressure reaches the set point operational pressure, TCU shuts off the F1 pump motor. Q3: when you say its a new model, is the electric motor itself new and different than the previous ones you were selling? or its the same motor?
The electric motor is the same, but the mounting plate for the new hydraulic gear pump heads is different. These new pump heads are originally designed by Marzocchi and their centering lip and shaft are 2 mm longer than those in stock pump heads from Magneti Marelli. Therefore, the mounting plate is 2 mm thicker and the centering cavity depth is 2 mm deeper to enable proper coupling of the pump head and electric motor shafts. So, if you want to upgrade the pump head for the motor and mounting plate you purchased from me before, you will need an additional 2 mm aluminum gasket, which I will be offering soon.
If you have additional questions, let me know.
