ive been working on a civillian coach.missing a compressor for the A/C.
list this info up as most here will never see one.

on top of the engine is a california emision standards label.
from nissan diesel.
its nissan family name is listed as TD422.
horse power -128 @ 4000 US horsepower.

powersteering pump is on the far right with long a section belt well clear of the engine.
alt is 100amp 24V on left.twin a section fan belts.
ac comressor[big zexell] is under the alt and uses a B section belt with heavy duty idler bearing.
4 pulley on crank

heater hoses both come out of the thermostat housing and a silly short 1/4 rubber hose is used as a bleeder pipe from under the thermostat to the water pump inlet that loops up to the top.the bus in most markets uses a second radiator on the passenger side in parrallel with the radiator.it uses a 12volt fan with a droping resister.only comes on when hot.

fuel filer in next to the VE injector pump where its hard to work on.no aneriod but it has a fast idle.
lots of insulted tin pannels around gearboxand flywheel for noise reduction.

front axle was a beam type.i think an independant is optional like the toyota coaster.under the bus they are very similar.it had alloy wheels that i havnt seen on older models.

these buses are built with lots of silly brackets.
2 examples.
fuel filter is mounted on a pressed steel bracket about a foot high.its bolted on to the chasis with reinfocement plate and welited bolts.at the top is a weilded plate at a 45 deg angle to possition the fuel filter and hand pump between the bracket and the body work away from the entry hatch.to remove the filter the assembley must be removed from the bus.
brake pipes.the front hoses that go to the disc calipers are fixed to a bracket on the body held on with 6mm bolts.a short steel pipe conects this to a manifold that is held in place by a complicated bracket with lots of big bolts and reinforcment plates as it uses a sandwich idea as there is no hose to use.another steel pipe returns to the body to continue back to the master cyl.
this is all very toyota.

hand brake lever is in the drivers door way.you sit on it as you slide out.if it hasnt hurt you,you forgot to apply it.

these buses in aust have a massive clock in the center top of the windscreen.

New in 1999. The Civilian Bus

same body style to that photo the older model was squared off.
engine interlock? im guessing it is the electric lock on the floor that stops the throttle pedal if the door is open,it has an noisey alarm,older model has no rear doors.

australian model-
exhauste is at ground level at the rear.there is different standards for a roof outlet.air intake for a/c is above windsceen.
engine-no EGR,no TPS and return to tank cut solinoid on top of IP- its a very basic pump,
air intake goes to the right with low bend to clear body and allow tappet adjustments,this makes it hard to change filters.i think the dip stick was in a better possition.

it has a throttle plate used for cold warm up. and no manifold glow plug.

the twin oil filers are used on all TD42.there is a oil/water heat exchanger inside the alloy casting it uses the water cooling the rear cylinders.there are take of points for remote coolers and fiters.from new there have been several oil filters are used oil pressure problems are common with early engines-this was fixed by removing the oil gauge

powersteer pump lower poviot bolts to the 4 bolt flange near the IP and the adjuster is bolted to the flange near the water pump.the pump sits outside of the engine line the injector pump is easy to work on.the patrol pump is much closer in to clear battery box.

i found that when the alternator was in at min adjustment the fan hit the water hose clamp.

you can see the silly hose at the front on the top photo.this is not used on patrols etc.the pipe is steel so it will rust,the clamps a sharp and catch you fitting the belts.whats the chance of getting a hose or plugs over a weekend.
