Do I have to remove the cyl head and samp to remove the fly wheel housing on Hino 500 truck

I got this free Pdf manual from reliable-store for free and I don't think Ive visited a me chanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 yearsmust try this bitman and reliable-store. Both are good

I need all the specs of Isuzu npr 4hg1 engine.Cylinder head bolts torque, crankshaft bolts torque, connecting rod caps bolts torque
.

You will need to remove the cyl head and check for corrosion and/or cyl head gasket. Best is to take the cyl head to a reputable machine shop for testing and service.

hino heave truck;
flat bed (=fb)

4 cyl gas or diesel , say real isuzu name of engine true name.

sounds to me 1992 any thing
bad power to cluster, (alternator bad or fooled)
do the head lights flare, surge?> that be first test, running.

use a voltmeter at battery
13.3 to 15vdc and steady?
must be. if is work the harness to cluster,
even a loose fuse can do this on very veh.

It's not a simple job. I recommend saving your time and paying a mechanic to do it for you.

I'd spray spray down with a good penetrating oil, let set for 24 hours or so, then using a hammer hit the bolt on the head (carefull of the fly wheel) then you may want to actually try to ever-so slightly tighten the bolts then go back and try to remove.

I hope this may have assisted,

if you havn' t done it before best to get an experienced technician to do it. [critical part, can cause major damage if incorrectly fitted]. before removing belt line up timing mark on crankshaft pulley with arrow on timing belt cover. remove inspection plug on top of gearbox bell housing. v cut away on fly wheel should be lined up with notch on g/box housing. timing mark on inside of camshaft pulley must line up with top of cylinder head surface at front of head. if distributor fitted, remove cap . rotor should be pointing to mark on distributor housing. remove old belt, fit new keeping timing marks in same positions. tension cambelt. should be able to turn belt 90 degrees side ways between cam pulley and intermediate pulley if tension is correct. reset ignition timing on completion.

check to make sure the starter is seated correctly to the bell housing also check for a cracked! nose cone on the starter as well and make sure the front nose casting bushing isn;t worn out and make sure they sold you the correct tooth count flywheel

there is a cover at the bell housing of the gearbox! remove its bolt then access the thin fly wheel! there are bolts that attach it to the torque converter! remove all as you rotate the fly wheel! pretty simple!
