This page contains information on the Standard Listeroids, as I have mentioned elsewhere, there are now a number of variants that are lighter and in some cases need to turn higher RPMs. Make sure your engine is a 'STANDARD' clone modeled after the famous Lister CS 5/1_6/1 before you make use of these specs. Use at your own risk, please report any concerns or errors.

 

Valve Adjustment when cold:  Intake .017" Exhaust .032"

Cylinder Head    -    160 to 170 lb-ft(23 to 24kg-m)

Fuel Injector      -     38 to 40 lb-ft(5 to 5.5Kg-m)

Connecting Rod -    50 to 60 lb-ft(7 to 8 Kg-m)

Housing for Main-Bearing    68 to 72 lb-ft(9.5 to 10kg-m)

Clearances

Crank pin to Rod, (Big End) there seems to be some confusion regarding this figure, one of the better Indian references specifies a maximum of .003 for this clearance, and states no minimum.

Other's state the ideal clearance is .003", Max clearance is .005  A number of folks were consulted in the old time engine community. A figure as large as .007 was found in some Lister material, but modern day folks think these figures are where they need to be.

With all this said... I'm going with the .003 and less figure, and I have no clue how tight this gap can be and splash oil properly. 

Here's some figures for clearance between piston top, an head, is is often measured with a peace of lead squished after head is fully torqued, remove and mic the thickness.

For Lister 6/1, 8/1 & 16/2 .....  0.060" - 0.065"
10/1 & 20/2............................ 0.080" - 0.085"
25/2 ....................... ................0.095" - 0.105"
 

Your engine may be different, but these are typical

Following is general Indian descriptions of the CS clones, and some parts info.

Following is there descriptions not mine!

Listeroid  vertical slow speed diesel engines are rated for maximum load for continuous running. This power is obtained at any level of elevation up to  700 ft. above sea level, with fuel oil of not less than 18,000 B.T.H.U.per Ib. The engine will give satisfactory service from any grade of fuel oil but preferably the usage's of clean light diesel oil is recommended. The engines are of compression ignition type with direct fuel injection, four stroke, vertical water cooled.

Construction Details
The cylinder head is made of high grade quality Cast Iron and is ensured in its design for effective running and minimum fuel consumption. The cylinder head cover is easily removable to give complete access to valve gear and atomiser. The cylinder is made of close grained Cast Iron and finally finished for exceptionally long life. Engines with replaceable cylinder liner can also be supplied if required. Piston is made of high quality Cast Iron and is ground to ensure good fit with the block with adequate clearance for satisfactory running.

 

It is fitted with four compressor rings and one oil ring. The valves are made of heat resistant high quality silicon steel and finished to ensure safe life. The crankshaft is made up of special EN steel ground to close tolerance. The main bearing are of bush type. The small end and the crankshaft bearings are of good quality white metal. Engines with crankshaft and taper roller bearings can also be supplied on demand.

The engine speed is controlled by spring loaded governor. The speed can also be adjusted while the engine is running. The governor controls the fuel pump with variable delivery and ensures that the required quality of fuel for any given condition of running is accurately maintained. The fuel injection pump delivery valve and the nozzle are the well renowned MICO (BOSCH) type. A large capacity fuel filter is fitted and is made of special fabric which is easily cleaned or replaced. The use of filter ensures long usage and trouble free functioning of the fuel injection system.

The engine is cooled by water circulation through the cylinder block and cylinder head with suitable inlet of outlet flanges provided in the sides. The engine is fitted with two well balanced cast iron fly wheels which keep the speed variation to the minimum under fluctuating load condition.

On every selected Listeroid diesel engine the best selected components are fitted for long life which are freely interchangeable with each other. Every engine is selected for fuel and load characteristics for varying load applications. They are specially painted and finished to have the best appearance and are supplied with the best packing fully lined inside the case. Each engine is supplied with fuel tank, starting handle, spanner set, oil can, screw driver, kept in a special tool box inside the case.

How to spill time the engine

The Indians didn't make it obvious where the timing mark was on these engines, It's a good idea to make your own now and 'spill time' the engine, this way you'll know where you are, and you'll have the proper marks for timing in the future. Take the head off, use a dial gauge, locate TDC, I choose to use a logical spot near the injector body to file my timing mark, after locating TDC, I then filed a mark in the fly wheel to align with the fixed mark. Now, it's just simple math to locate the mark where the injector pump stroke begins, my reference material says 18-20 degree BTDC 'before top dead center is the spot. Simply do the math and realize that a single degree is going to be quite a distance on this big ole flywheel, this is vastly easier than almost anything most of us have seen before.
While you have the head off, clean up the head gasket, liberally paint acrylic floor wax on the inside of all water passages and all the way around the outside of the gasket, then wipe down the sealing surfaces. Use cheap Aluminum paint and mist on a thin coat on both clean sides and allow to dry. Before you put the head back on, run your fingers over all surfaces checking for any little bits. Make sure all is clean dry and free of dirt, also put in back in the same orientation you found it. Clean the top of the piston and combustion chamber while you're here, there may be some carbon due to the overload test at the factory.
Simply measure the distance around the flywheel with a good tape measure. Example: measure from the 12 inch mark and subtract 12 inches, this removes the error often found in the end of the tape. One you have this measurement, divide it by 360 to get the distance per degree, and then multiply that by 20 to get the 20 degrees before TDC mark. Make sure you LEAD the TDC mark in the proper rotation, on the injection pump side of the engine! Simple for those of us who have been around engines, but this is a dandy beginners engine, so we'll be verbose. My example, I used the metric scale.... 1887MM circumference, divided by 360, then multiply that by 20 gave me about 10.5CM prior to TDC for my spill timing mark.
Once you've found your 20 degree mark, file it in, you might even rub some white paint into the file marks and label them.
Now for the timing, ...... run the engine, get all the air out, stop the engine, loosen the high pressure fuel line from the injector, place a tight fitting piece of clear plastic over the fuel line holding it straight up in the air, Note that some folks then fit a smaller plastic tube inside the first one to get a finer reading. now turn the engine over, compression release on, throttle rack open, and get fuel into the plastic, so you can see the fuel. Now slowly turn the engine and note the spot where the fuel just begins to pump. See the adjustment under the injector pump, raise or lower it depending on how far it's out. A warning to the wise, stick your finger under the injector, and there's a good chance you'll loose part of one when the flywheel is turned! keep your mitts out of the moving parts!

the crank shaft is approximately 3 feet long, fly wheels are clear of the ground on the model I am familiar with. Twelve two's on the other hand, have wheels that often hang lower that the base of the engine itself.

Shipping crates for six ones are 43" tall, 38" wide, 24" long. the crate itself will heat your shop for a full day if you have a wood stove. some of the wood is very dense and has a nice grain to it, you might save some of it for a wood working project.

Fuel efficiency:  Actual tests using the  Listeroid 6/1, ST3 head, and the efficient Allmand drive system produced .125 gallons of biodiesel per KWH.   We are working on a few simple MODS that could boost this REAL number even higher. Following is a formula from Jeff Maier that will predict 6/1 fuel usage for this setup.

Fuel Usage Per Hour          (Gallons/Hour) = (Load in KW) * (0.0918) + .101
