German bulldog tractors by Don

[08/19/19]

  Hi this page will give you some idea of the differences between the German Bulldog tractors that ran on what back then was called diesel fuel a sort of heavy diesel as we no today, whereas the British field Marshall tractors ran on distillate which is the diesel we no these days, both manuals are available from tractor manuals downunder …
Field Marshall
STARTING AND STOPPING
GENERAL AND HAND STARTING
Before starting each day, check the lubricating oil level and fill fuel tank. Add water to the radiator if necessary. Also pay attention to the necessary greasing (see Figs. 53 and 54). Some users prefer to fill the fuel tank after the day’s run. This tends to reduce the amount of condensation. Declutch the engine by pushing forward the hand clutch control lever (Fig. 12). Immediately the engine starts re-engage the clutch.
Having checked that the gear change lever is in neutral and that everything else is in order, remove ignition paper holder (Fig. i) and turn the engine slowly round two or three times with the fuel lever (Fig. 2) in a position two-thirds open, i.e. towards the driver.
It should be possible to hear the slight’ purr’ of injection taking place as engine is turned over by hand. If starting by hand, see that valve on cylinder head is in the hand start position (Fig. 7.).
Set the decompression gear by taking hold of the lever (Fig. 3) so that the valve in cylinder head is open and at the same time pull outwards so that the roller is engaged on the thread on the flywheel rim nearest the operator. Having set the decompression gear, roll a piece of ignition paper (a quantity of which is supplied with the tools) into a tight, neat roll and insert in holder. Light and blow on it to make it glow, and carefully replace holder with burning ignition paper in the cylinder head, seeing that it is screwed tightly home. Give holder handle a slight tap with spanner to ensure seating, otherwise leakage of gas past the holder will carbon up the stem, make it difficult to remove and cause loss of power.
The tractor should now be turned over smartly by means of the starting handle in an anticlockwise
direction. When the decompression roller leaves the flywheel thread after about four revolutions, the decompression valve in the cylinder head will close, and the engine should fire.
If starting is not successful at the first attempt, the decompression gear should be re-set, a fresh ignition paper inserted, and the operation repeated. Remove starting handle immediately the engine fires by withdrawing outwards. Sometimes when starting, the engine accelerates to full speed, then stops firing and slows up. It can be usually prevented from stopping by pulling the compression release cable and holding the valve open for a few revolutions of the engine. On releasing the cable, the engine will start firing again.
After the tractor has started, allow engine to run up to speed, and then close down the fuel control lever to half-speed.
Allow the engine to run for a minute or so at half-speed in order to warm up, and the tractor is then ready for work. If possible avoid heavy pulls until the tractor is thoroughly warm. Should the engine be stiff when starting after a period of idleness, or during cold weather, starting will be assisted by decompressing the engine and turning round several times with the’ fuel control lever fully open, but without ignition paper holder inserted.

Lanz Bulldog
TO WHAT POINTS MUST SPECIAL ATTENTION BE PAID WHEN OPERATING THE BULLDOG?
During first 100 hours of operation do not permit engine to run at full load (only —j or 3/4 load).
After first 100 hours of operation drain oil from crank case {Mq. 12) and from lubricating oil tank (No. 11), and also clean oil filter (No. 58). Once a week clean perforated cylinder jn exhaust upper pari (No. 70). After every 300 hours of operation drain oil from lubricating /oil tank (No. 11),
clean oil filter (No. 58), as well as the strainer in the crankcase base plate
(No. 61), and the exhaust (No. 70). After every 1000 hours of operation clean inside of
engine (No. 72—75). After every 1500 hours of operation clean the gears (No. ;8Q)
and the Bosch
lubricator (No. 60).
** Before Beginning To Work;
1 Fill up lubricating and fuel tanks(No. 17)/and check water.
2. if tractor has been idle for several days, prime lubricating oil (No. 10).
3. Check to see that air cleaner is clean, and if necessary, clean it; if it is dry, moisten it with oil (No. 23).
4. Lubricate the parts of the Bulldog listed under No. 15. P 5; Adjust atomizer correctly (No. 19).
Starting Engine
with electric starting with ignition (for starting with blow lamp see No. .-31); Open petrol stop valve of petrol tank (No. 18).
2. Open petrol stop valve on dashboard (No. 18). (Gas-oil stop valve remains closed.)
3. Set fuel lever for medium load (No. 34).
4. Remove right-hand cover guard,
5. Turn on ignition (No. 25).
A barriosbooksales reprint
6. Prime petrol (3—5 strokes) (No. 20).
7. start engine with starting wheel (No. 30 g).
8. Open gas-oil stop valve (No. 18).
9. After 3—5 minutes running time: turn off ignition, close petrol stop valve on dashboard (no. 33).
While Working:
1. From time to time check oil supply in lubricating oil tank (No. 8).
2. Adjust fuel lever properly (No. 34).
3. Never overload engine for any length of time.
Shutting Down:
1. Open petrol stop valve on dashboard (No. 18).
2. Close gas-oil stop valve (No. 18).
3. Turnon ignition,
let engine run for one minute,
4. Set fuel lever all the way back (No. 34).
5. Close petrol stop valves (No. 18).
6. Turn off ignition.
After Shutting Down:
1. Pour a few drops of petroleum into cylinder through filler petcock (No. 35).
2. Clean air cleaner (No. 23).
3. If frost is forecast, drain radiator completely (No. 3).
4. Subject exhaust to an early and thorough cleaning (No. 70).
5. From time to time inspect the cylinder head for scale in the cooling water compartments (No. 54).

Bedford Diesel engine wsm: A Snippet

!n many cases, a mechanic is justified in replacing
parts with new materiai rather than attempting repair.
However, there are times where a slight amount of
reworking or reconditioning may save a customer
considerable added expense. Crankshafts, valves and
other parts are in this category. For example, if a
cylinder is only slightly worn and within usable limits, a
honing operation to remove the glaze may make it
suitable for reuse with a standard size piston and new
piston rings, thereby saving the expense of new parts.
Various factors such as type of operation of the
unit, hours in service and next overhaul period must be
considered when determining whether new parts are
installed or used parts are reconditioned to provide
trouble-free operation.
For convenience and logical order in disassembly,
the various subassemblies and other related parts
mounted on the cylinder block will be treated as
separate items in the various sections of the manual.

DISASSEMBLY
Before any major disassembly, the engine must be
drained of lubricating oil. Water and fuel, On engines
cooled by a heat exchanger the fresh water system and
raw water system must both be drained. Lubricating oil
should be drained from any power transmission
attached to the engine.
To perform a major overhaul or other extensive
repairs, the complete engine assembly, after removal
from the engine base and driven mechanism, should be
mounted on an engine overhaul stand; then the various
subassemblies should be removed from the unit. When
only a few items need replacement, it is not always
necessary to mount the engine on an overhaul stand.
Parts removed from an individual engine should
be kept together so they will be available for inspection
and assembly. Those items having machined faces,
which might be easily damaged by steel or concrete,
should be stored on suitable wooden racks or blocks or
a parts dolly.

The cleaning procedure used for all ordinary cast
iron parts is outlined under “Clean Cylinder Block” in
Section 1.1, while any special cleaning procedure will
be mentioned in the text wherever required.

Steam C leaning
A Steam cleaner is a necessary item in a large
shop and is most useful for removing heavy
accumulations of grease and dirt from the exterior of
the engine and its subassemblies.

Solvent Tank Cleaning
A tank of sufficient size to contain the largest part
which will require cleaning (usually the cylinder block)
must be provided and provisions made for heating the
cleaning solution to 180 degs. F.
This tank is filled with a commercial heavy-duty
solvent which is heated to the above temperature.
Large parts are lowered directly into the tank with a
hoist; smalt parts are placed in a wire mesh basket and
lowered into the lank. The parts are immersed in the
cleaning tank long enough to loosen all grease and dirt.
When lowering components into the tank mantlla
rope slings should not be used as the chemicals used in
degreasing tank will rot the rope enuring a possibility
that units could be dropped, it is advised that wire rope
slings are used.
WARNING: Caustic based solvents should not be
used for parts containing Aluminium. Check before
using.

Rinsing Bath
Another tank of similar size containing hot water
should be provided for rinsing the parts.

CLEANING
Before removal of subassemblies from the engine
(but after removal of the electrical equipment) the
exterior of the engine should be thoroughly cleaned,
ensure that exhaust and air intake are suitably sealed, if
steam cleaning is used. Then after each subassembly is
removed and disassembled, the individual parts should
be cleaned.
Thorough cleaning of each part is absolutely
necessary before a part can be satisfactorily inspected.
Below are listed various items of equipment needed for
general cleaning.

Drying
Parts may be dried with compressed air. The heat
from the hot tanks will quite frequently complete the
drying of parts without the use of air.

Rust Inhibiting
If parts are not to be used immediately after
cleaning, they should be dipped in suitable inhibiting
compound. Remove the rust proofing compound
before instaiing the part in an engine.

Fordson by Don

[08/30/19]

After the well known Fordson kero tractor,with its sibling powered by the P6 Perkins engine came the NEW Fordson powered by its own Ford engine …engine titted in the New Fordson Major Tractor has a bore diameter of 100 mm, and a stroke of 115 mm.
Overhead valves are employed operated by push rods from a gear driven camshaft located in the right-hand side of the cylinder block. The compression ratio is 16 to 1.
The valves are fitted vertically in the cylinder head, the inlet valve head being larger than the exhaust. The valve guides are replaceable.
Aluminium alloy pistons are employed with a combustion chamber machined in the crowns and have three compression rings and one oil ring above the piston pm and one oil control ring below the piston pm. The piston pins are fully floating and are retained in position by two circlips.
Detachable wet cylinder liners are fitted, flange-mounted in the top face of the cylinder block and retained in position by the cylinder head.
The crankshaft is supported in five large diameter mam bearings. These bearings and the connecting rod big end bearings are of the detachable steel-backed lead-bronze type. Crankshaft end-float is controlled by detachable thrust washers fitted at each side of the centre main bearing.
An enclosed camshaft type fuel injection pump is driven from the rear end of the auxiliary drive shaft and feeds multi-holed type injectors located at an angle in the top of the cylinder head.
The engine speed is controlled by a pneumatic governor mounted on the fuel injection pump. An excess fuel device is fitted to assist cold starting.
On current engines rotator type exhaust valves are fitted. A cap located over the end of the valve stem transmits pressure from the rocker lever to the spring retainer and valve spring. This anion allows the valve to remain free throughout its operating cycle.
A decompressor, operating on all valves, was fitted to early type engines. On current engines this is optional equipment.

Allis-chalmers Hd-7w yr 1942 service manual: A Snippet

DESCRIPTION (figs. 1 to 10).
a. General. This tractor is of the crawler or track-laying type and
may be used for either highway or cross country travel even under the
difficult operating conditions presented by mountains, swamps, sand, or
unbridged ditches. Because of its relatively low center of gravity, the
tractor can easily climb slopes as steep as 30 degrees depending on the
kind of footing available and the load being pulled.

b. Engine. Power is supplied by a water-cooled, 3-cylinder, valve-
in-head, 2-cycle Diesel engine. A multiple speed transmission is used,

offering 4 forward speeds ranging from 2.64 miles per hour to 8.35 miles
per hour and a reverse speed of 3.14 miles per hour at full throttle

engine speed. The fuel tank has a capacity of 120 gallons which per-
mits about 20 hours of operation without refueling.

c. Steering. Steering is accomplished by means of steering clutches
operated by 2 levers mounted in the center of the tractor within easy


reach of the operator. Each lever controls a multiple disk steering
clutch through which power is delivered from the transmission to the
drive sprockets.
d. Seat. The seat has removable cushions and safety straps and will
accommodate the operator and one other man.
e. Winch. The winch is mounted on the front of the tractor and is
driven by a reversible power take-off from the tractor transmission.
A control lever for the power take-off is just ahead of the seat and in
easy reach of the operator.

f. Equipment. Equipment on the tractor includes batteries, elec-
tric starter, generator, lights, mile meter (odometer), engine air heater

and engine preheater for cold weather starting, fire extinguisher, snatch
block, tow chain, and loose tools.
g. Tractor and Engine Numbers. The serial number of the tractor
is stamped on the master clutch inspection cover, and also on the rear
