The image below shows a typical McCulloch Installation kit, with this one being for a 1956 Plymouth. Sorry about the large size and subsequent large download time, but I felt it would be useful to show this, and didn’t want to compress it too much as a lot of detail would be lost.
The constituent parts of this kit are:-
1) Supercharger
2) Mounting bracket
3) Idler Arm assembly
4) Retaining Rings and Washers
5) Crank Pulley
6) Belt
7) Hose – Supercharger to Carburetor
8) Hose – Supercharger to Air Cleaner
9) Air Cleaner
10) Bracket to support Hose
11) Bracket to support Air Cleaner
12) Carburetor Modification Kit (Carter in this example)
13) Resistor Assembly
14) Electric fuel pump kit
15) Manifold Vacuum Switch
16) Carburetor bonnet
17) Hose – Supercharger to fuel pump
18) Hose – Vacuum switch to manifold
19) Nipple – Manifold
20) Nipple – Fuel pump
21) Hose Clamps for Supercharger to Carburetor Hose
22) Hose Clamps for Supercharger to Air Cleaner Hose
23) Spacer for engine cooling fan
24) Shims for the engine mounts
25) Wire for electrically connecting the Vacuum switch to ignition and Supercharger.
26) Grommet strip for interface between Air Cleaner and bracket, to reduce resonance.
27) Screen for air cleaner inlet
28) Stud for bolting bonnet to carburetor inlet.
29) Spacer used for extending the bonnet height, as required on some installations.
30) Hose for connecting bonnet to carburetor float chamber/secondaries
31) Baffle for float chamber of carburetor
32) Gasket for mounting of carburetor on intake manifold.
33) Accelerator pump seal assembly
34) Gasket for mounting bonnet onto carburetor
As you can see the kit was pretty comprehensive, and contained everything required in order for a dealer to install the kit on the required application. Obviously nowadays we are not going to find the majority of these parts for the system, more specifically the gaskets, hoses, nipples, spacers, electric fuel pump, etc., however we are fortunate in that modern, more reliable, replacements can be found for some of these parts, and with minimal rework can be adapted to allow us to set up a McCulloch system.
