[Mg-mmm] Lube for Marshall 75

[Hiro Nishio]

Dear Chris,

Thank you for your advice. Yes, I will put some small diameter copper pipe 
from cylinder head with metering pin inside to control the oil supply to 
6 drops per min.

I add some castor oil to the fuel to enjoy the smell! But it will not lube 
the gear driving Roots blower rotors

Thanks and best regards,
Hiro

Hiro,

Lube for blower is definitely needed.  We are running MK22 spitfire blower
on our P-Type (Marhsall style).  We have run about 6 drops per minute with
no problem for many years.  This is just fed from the sump and I run a
15W-50 generally.

Just increase the amount of drops when you are racing.  You will know when
you have too much as you will start to foul plugs at high speed.

Alternative is to put oil in fuel.  On R-Type we use a fully synthetic oil
in the fuel as it dissolves easily.

Let me know if you need anymore.

Chris

Dear MMM friends,

Recently I purchased and installed a Marshall Z 75 to my J2 racer.
It is driven from crankshaft at engine speed and gives around
10psi - enough for the road use.

Now I have a question - oil (I use 20W-50 mineral) to lubricate 
gears is going out to the inside of the blower through the 
shaft very quickly, and I wonder if some continuous lubrication 
is necessary.
Some book says "6 drops per minutes" supply from cylinder head 
using metering pin is appropriate...

Awaiting your experience and advice. Thanks.
