Also note:
If at the end of this process I accept the winning bid, the winning bidder will then have the opportunity to make further offers on any or all of the following information packages:
1. Complete set of detailed engine accessory drawings and specifications, for Lister CS 8/1 build 01 engine. Accessories are: air filters, silencer, fuel tank, flat belt pulleys, starting handle, cooling
water tank arrangements, suggested foundation arrangements and holding down bolts, drawings of engine transfers, and tool list.
2. Build 01 GA drawings for 8/1 and 16/2 engines, showing key maximum external dimensions.
3. A feasibility study conducted by Lister concerning the possible supply of Indian cloned Lister CS engines using the Lister name and distribution network. Which consisted of the following
activities:
• Obtaining an Indian manufactured engine from one of the more reputable manufacturers. Produce a visual inspection and strip report (which also detailed damage caused by poor quality
control during initial assembly of the engine). Crankcase and other castings cleaned internally to remove any residual casting contaminants, and reassemble the engine using only Indian
sourced consumable items (gaskets, piston rings, big end bearings, and oil seals, which came with the engine, as part of the spares package).
• Run the Indian engine; on a 200hr WOT dynamometer test. Note! The Indian engine required constant nursing and numerous failed parts replacing with further Indian sourced parts to
get it through the test.
• Remove engine from dynometer, and produce another strip report, and reassemble and extensively blue print the engine. Replace any worn or defective components using only Indian
‘export quality’ sourced spare parts as required.
• Repeat 200hr WOT dynamometer test. Note! The Indian engine still required nursing and also items replacing with further Indian sourced parts to get through the test (though less than
the previous dynometer test).
• Remove engine from dynometer, and produce another strip report, and reassemble and blue print the engine again. Replace any worn or defective components. This time using only
genuine Lister spare parts as required.
• Repeat 200hr WOT dynamometer test. Note! The Indian engine now required only minimal nursing and also some items replacing with further Lister sourced parts to get through the test
(though now much less parts replacement than the two previous occasions).
• Obtain a Lister CS 8/1 engine from the on-site training school at Dursley, strip, and reassemble(under assembly line conditions and time constraints).
• Run the Lister 8/1 engine; on a 200hr WOT dynamometer test. Note! The engine required some items replacing to get through the test (attributed to damage to oil pipes inflicted by many
strip and rebuilds in the training school, which only became apparent once the engine had been run under load in the test cell).
• Remove engine from dynometer, and produce another strip report, reassemble and blue print the engine. Replace any worn or defective components, using only genuine Lister spare parts
as required.
• Run the Lister 8/1engine; on a 200hr WOT dynamometer test. Note! This time the engine required no attention (with the exception of minor oil leaks), neither did it require any items
replacing to get through the test.
During the above tests, the following parameters were constantly logged: ability of engine governor to maintain set speed, coolant flow and return temperature, exhaust gas temperature,
exhaust gas emissions, humidity and temperature of inlet air, oil temperature, crankcase vacuum. Throughout the above test regimes regular oil samples were also taken for later analysis and
comparison.
The strip reports (for the Indian engine) also details: Oil analysis results, measurement of surface finish roughness on critical bearing surfaces, dimensional and geometric inspection of all critical
components, and then goes onto compare the recorded dimensions to the respective Lister CS drawings
The result of the above tests allowed Lister to identify the many deficiencies that existed on the Indian sourced engine that required addressing. Which would be required in order to improve
the quality and longevity of the engine to an acceptable level, prior to bringing it to market under the Lister name.
4. A material composition and physical properties report generated from samples cut out of key components of the Indian engine. Tests include: tensile testing, impact testing, and fatigue testing
(only on big end bolts and for both Indian and genuine components).
Report also contains:
Measurement of Brinell hardness, of all heat treated components, and comparing results to Lister specifications. Preparation of metallographic specimens clearly showing: contaminants present
in the metallographic samples at the grain crystal boundaries, slag intrusions on forged components
Results of mass spectrography, which details the exact material composition by percentage, including contaminants
5. Rationalisation study of the Lister 8-1 engine, investigating how alternative production techniques / materials could reduce production costs. For example proposals for alternative methods of
camshaft manufacture.
Also details of further components that could be eliminated from the engine (i.e. use of a single valve spring from another engine range, in place of the double valve spring arrangement)
Weight saving measures that could be implemented, such as lighter weight flywheels, and substitution of sheet metal and or Aluminium alloy castings for previously cast iron components.
6. Build sequence for 8/1 engines.
7. Minimum list of tooling required for production line assembly of the 8/1 engine.
8. Results obtained from a WOT 200 hour dynometer test of ‘export quality’ fast moving Indian spares (pistons, bearings, valves, fuel injection parts) in a genuine Lister CS 8/1 engine, and
reporting on the engine performance and wear results obtained, using same methodology as item 3 above.
9. Drawings of most (though not all) of jigs and fixtures required to manufacture the 8/1 Lister CS engine finished components.
NOTE! These drawings range from extremely sophisticated multiple operation machining fixtures to very simple sketches of crude pipe bending fixtures. These fixtures date from the pre CNC era,
when mass produced components were machined on Capstan/Turret Lathes and holes were drilled and tapped using multi-station drill bank type machines.
10. Option studies of various improvement schemes to the 8/1 engine, such as conversion to direct injection, electric start, internal balance weights, etc.
11. Calculations for out of balance forces, compression ratio adjustments, calculations to quantify the effects of assembly/production tolerance errors on valve timing events, calculations to quantify
the effects of more aggressive inlet exhaust cam lobe profiles on valve timing events, and effects upon cam lobe and follower contact area, calculations of moments of inertia for rotating masses
to derive cyclic irregularities for different weights of flywheels.
12. A significant quantity of memos and sketches detailing blue sky thinking. Which detail all sorts of ideas for possible implementation to further improve the engine and maintain market share.
i.e. production of a VA2 engine, and a natural gas version of the 8/1 engine. Obviously as we now know, none of these schemes were actioned.
Finally I will try and answer any question you may have, as I am sure there will be many
