hello welcome to our series of videos

from which we're going to take an

in-depth look at various tanks we're at

the military vehicle technology

foundation in Portola Valley California

and this episode we're going to have a

look at the rim 26 known as the Pershing

young corny six is defined in the manual

as a heavily armored fully tracked

laying combat vehicle of low silhouette

with torsion bar suspension and

individually sprung load wheels that was

this may seem pretty self-evident to us

now it is important to remember how much

of a change this was from this

predecessor the m4 medium known as the

Sherman now we're going to be having a

look at this vehicle in two segments

firstly the exterior and powertrain and

then the crew compartment so let's get

crackin the whole consists of cast

sections front and rear which are welded

to the hull sides there is another cast

segment which goes across the engine

deck that's for strengthening at the

front you'll see your horn black out

markers service drive lights to lifting

eyes to towing eyes 30 Cal and

underneath we're going to have a drain

valve which drains water off the bottom

of the tank

the suspension consists of six pairs of

road wheels each pair being mounted to a

road wheel arm on its own torsion bar

the number one road wheel arm is

physically connected by way of an

eccentric spindle to the adjusting idler

what this will do is as the road wheel

arm comes up it will push the idler

wheel forward and thus maintain track

tension jarm is also equipped with a

bump stop and what this does is it

limits the range of motion of the arm

number is one two five and six arms are

also equipped with shock absorbers and

what these will do is reduce the rocking

effect of the torsion bar suspension the

idler is also have the track tension is

adjusted to do this where you do is you

get a very large wrench and you loosen

the lock nut you then take an even

larger net wrench and with the aid of a

cheater pipe and usually two or three

burly lads

you will then physically lever the idler

forwards or backwards to change tension

once you've done that you then lock up

your locking nut again and away you go

now the track ten

is checked by placing one inch blocks on

the numbers 2 & 4 road wheels and then

you check to make sure you have a one

quarter inch gap above the third three

to track were available steel rubber or

these rubber backed steel Chevron's

there are 82 links per side

the tracks are connected in a manner

familiar to modern tankers you have end

connectors with wedge bolts and

two-piece Center guides the thank you

for a telephone is rather securely

mounted to the right rear of the vehicle

everyone will come up bring the

telephone up push the talk and then when

he started replace it back into its

mounting

so after having traverse the turret so

that we could open up the engine

compartment we can now see the four GAF

this v8 engine developed from the Ford

GAA of the m43 cranks out 500 horsepower

with the maximum rpm of 2,800 uses a wet

sump lubrication system the dipstick for

which is located right there all right

now the auxilary engine is a 13 point 6

horsepower 4-cylinder engine which runs

at a constant 1,800 rpm has an automatic

choke used to drive the generator when

the batteries have to be charged or

auxilary electrical equipment is needed

and the engine is not running can be

started either electrically or shady

failed to notice the battery drain by

use of a manual handle there are two

fuel tanks on the vehicle the one on the

left side is 116 gallons the one on the

right side however is a little bit

shorter 75 and a half gallons because

has to leave room for the axillary

engine and the generator so as you move

more towards the rear of the vehicle

what we have here is a radiator filler

cap the gun travel lock and down

underneath here is the transmission this

I have three speeds forward one reverse

transmission oil level differential oil

level this is the controlled type

differential so called because it

actually controls a steering one this is

is one of these steering linkages as you

pull back on the brake handle this will

move and apply brake pressure to three

drum brakes per side on the differential

final transmission of the power is

conducted through the universal joint

out through the final drives and then

the sprocket wheels

alright so that's it for the engine

compartment next time we're going to

move into the drivers hole
