Why a SAMFAQ? [Mike Graham] As of May 1997, I will be a proud Sammy
(“pet” name for Samurai) owner. Prior to that event, I wanted to get info on
possible upgrades etc. that I can perform. Although the Sammy will primarily be
a daily driver for use while I'm doing a frame-off resto on my Land Cruiser,
it deserves far better than to suffer the ridicule of being road-bound. My
'cruiser buddies are giving me some good natured ribbing for buying a Sammy
('cuz it's so small, eh? With twig-like drive-shafts that bend in the
breeze, etc. etc. etc.), so it is a moral imperative that I build it up to the
point where it will blow their 'cruisers out of the water. Fair is fair. 8-) So I went looking for info. “Where's the
FAQ?”, I asked. There wasn't one. This is a situation that cannot go on! A
FAQ is needed, so here it is. You might be worried about the fact that I know
virtually nothing about the Samurai, and don't, in point of fact, even own one
(yet), and yet here I am providing an authoritative information source. Welcome
to the internet. 8-) The information within this tome is provided by people who
have real experience and knowledge. I'm just the compiler of this FAQ. Think
of me as a news anchorman. When was the last time one of them was
actually covering a cocaine war somewhere? As a final note, I should point out that this
document is off-road oriented; some of the maintenance info will be pertinent to
the pavement dweller, but the document is directed at the seeker of the trail

1. | | | | 1.1 | What is a Samurai? The Samurai (as it is known
in the USA) is a short wheel-base 4x4 sport utility vehicle
(SUV). It was available in both hard-top and convertible
models. Standard was a 1300cc single-overhead cam engine and
leaf springs. | | 1.2 | What years were they
imported to the United States? 400,000 Samurais were
imported from 1986 through 1995. | | 1.3 | What other names refer
to the Samurai?| Australia | | | Sierra | | Parts
of Asia | | | Caribbean,
Caribian | | Japan | | | Jimny | | Various
Countries | | | SJ413 |
| | 1.4 | What are the biggest
tires I can run? [Noel Van Hook] Height: Pure stock with
biggest you can fit is 27". Mickey Thompson and Interco
both make nice 27x9.5 tires that will fit stock no problem.
A 215x75R15 will fit also. People will say you can go
bigger, but any larger will rub under full
suspension compression! Lots of people don't care about
that, and so put 28" tires on anyway. With a 1" shackle lift
(2" longer shackles) and minor trimming on the front
bumper you can fit 29" tires. This includes 235/75R15
tires. Trimming is easy. It can be done with a hacksaw, and
is done on the inside of the bumper, so it doesn't show.
The shackle lift is easy too, and 1" is small enough
that the stock shocks will work. Width: Pure stock the widest
you can go is 9.5". Any wider and you rub the bumper
when turning the wheel. With minor bumper trimming (see
above) you can go to 10.5". You can use standard
3.5" backspacing and you’ll still clear the springs
at full turn. What I have: I run 29x10.5
swampers on 15x7 wheels, standard backspacing. To get them
to fit I added a 1" shackle lift, and trimmed the front
bumper. No fender trimming was required. They do not rub,
ever. The truck has a nice wide, aggressive stance. The
wheels hang out about an inch from the fender flares, so
they do tend to throw the mud around. But they also do a
good job of protecting my fenders from damage, too. [Larry
Harris] | Tire

make to improve general trail-worthiness if I only have
$1000 to spend? [Mike
Graham] When I asked this question, I
got several different answers to this one. Here they are: Jonathan Hall says: “Lock
right, s/o, diff gears.” Noel VanHook says: “Rock
Lobster and tires.” James Hiers says:
“Rocklobster transfer case and lockrite.” I'm going to amalgamate
these answers and come up with a different one. I'm going
to say that for general trail running the best $1000 spent
to keep you moving is going to be spent on a lockrite and
tires. A rocklobster is a great thing to have if you're
playing on steep rocks, but a locker and tires is the best
$1000 you're going to spend for general trail use. If
you're building a rock-crawler, then the rocklobster and
s/o just might be your best route, but never underestimate the value of good tires. Oh yeah, I'd put
that locker on the front. Now, if you're planning on
putting big tires on it (like 30s; see the section
on tire sizes) then you may well be better off going with
Noel VanHook's suggestion of tires and a rocklobster,
because the increased tire size is going to reduce your
torque, which the rocklobster will compensate for, both on
and off road. |

2. | | | | 2.1 | How tough
are Sammies? Although many of the
drive-train components are tiny to the point of being
“cute”, they are more than strong enough for the stock
engine. When you start swapping in bigger engines, or
increasing the power of the stock engine, and then start
hurling your Sammy down boulder-strewn passages that a
mountain goat would think twice about attempting, that's
when you start breaking things. Of the stock drive-train
components, the only consistent breakage (and again, this is
only in extreme situations) is u-joints, and even then only certain people, like Glenn Wakefield, break them regularly. I think
it's a Karmic imbalance thing. 8-) There have been reports
of aftermarket diff gears breaking if they're not set up
just right. | | 2.2 | How do I
get more power out of my 1300cc engine? [Mike
Graham] Whether the engine is fuel
injected or not, it can benefit from: - K&N air filter ($50)
- MSD Ignition system
- Tri-Y exhaust header
- 2" Free-flowing
exhaust
- Performance camshaft
The favorite seems to be the
header and 2" exhaust. Almost everybody asked put that
in their top 3 mods to make to a 1300. If the engine in question is
carbureted, then look into replacing the stock carb with a
Weber. | | 2.3 | How do
you get the @#$& valve cover off? [Mike
Graham] When the crank is turned by
way of the crank pulley center bolt (using a 17mm socket) to
the TDC point (the white notch on the crank pulley is lined
up with the “0” on the ignition timing marks), then the
intake valve rocker on cylinder #4 will be enough out of the
way that you can raise the front of the cover (after
removing the bolts, of course) and roll the cover to the
right to sneak the back left corner out from under the
vacuum advance on the distributor. Getting it back on is
just a real drag in the dirt. This is going to sound
excessive, but I honestly find it easier to pull the
distributor. Really. Firstly, use a scriber to make a mark
on the dist body and the mount, so that you can easily
realign it. Once you have the crank at TDC you just remove
the distributor hold-down bolt, and the whole unit slides up
and out. Even if you don't want to actually pull the dist,
you can just turn it clockwise a few degrees to move the
vacuum advance out of the way, and you will find that life
is much, much easier. This is far easier
than screwing around trying to get the cover off with the
distributor in place. When the cover has been replaced and
bolted down, just turn the distributor body back so that the
marks line up again, and tighten the hold-down bolt. I
usually check my ignition timing afterwards, but you can get
away with not doing it if you line your marks up correctly.
If you later decide to permanently change your ignition
timing, just sand off the old marks, set the new timing, and
make new marks. | | 2.4 | How do I
relocate my breathers? [Mike
Graham, with info from Thom Batty] Get yourself 15' or so of
plastic tubing with an inner diameter of ?". Using a
pair of vise-grips, remove the cap from each breather,
attach the end of the hose and fasten with a hose clamp.
Using zip-ties, run the hoses to the engine compartment
(leaving enough slack near the axle for axle travel) and cut
off the extra hose. You can end the hose in one of two ways;
either spend the money on some inline filters (fuel filters
or whatever) and top the hoses with that, or just end the
hoses in an arch like the top of a candy cane; if the open
end of the “candy cane” runs down about 8" or so,
you won't need to worry about water getting in. Higher is
better. If you run a snorkel, then just plumb the hose into
the snorkel so that it uses the same air supply. | | 2.5 | How do I
get the slop out of my steering? [Larry
Harris] There is a lock nut and
adjusting screw on top of the steering box. The proper way
to adjust it is with the preload method. You will need a
spring scale to measure the starting torque of the worm
shaft (the one with the rubber piece that goes to the
steering shaft) it should be between 1.58 - 2.63 kg when
adjusted properly. There have been many that
just turn in on the screw a little to remove the free play.
Be careful with this method, but it does work. Do
not over-tighten the screw. Make a small
adjustment and cycle the wheel from stop to stop and make
sure it still has free travel with no hard spots. | | 2.6 | How do I
re-center my steering wheel? [Larry
Harris] The steering wheel can not be
re-centered unless you remove the wheel itself or the
u-joint on the steering shaft. The only adjustment we have
is for toe. To remove the wheel, pull off
the horn button and loosen the nut holding the wheel in
place. Don't remove the nut completely, so's not to bop
yourself in the nose with the wheel. Pull the wheel free (a
puller is not required). Remove the nut, reposition the
steering wheel and fasten it back down. |

4. | | | | 4.1 | Why does
my Samurai hesitate when I accelerate? [Gary
Munck] The secondary throttle plate
is operated by vacuum, there is a little hole that is the
port for this vacuum. The flat spot you are feeling
is caused when the secondary either does not open or opens
and then closes partially as the vacuum drops in the
manifold. I hope this clears up the mystery. On most carbs it is necessary
to move the opening of this port out into the air flow.
There is a small tube available that can fix the problem in
the majority of Samurais. For more information see: http://www.off-road.com/suzuki/tech/tb4-06.htm | | 4.2 | Whydoes my shift lever wobble around? [Off-Road.com] Because the locating pin
that's supposed to hold it in the proper position has
broken off. You need to replace it with a new one, both an
easy and a cheap fix. See: http://www.off-road.com/suzuki/samurai/shiftlever.htm for full details. | | 4.3 | Why is my
shift lever stuck? [Mike
Graham] Because the locating pin
that's supposed to hold it in the proper position has
broken off and things got way out of whack. See 4.2 immediately above. What is actually happening is
the toe of the shifter is caught somewhere it isn't
supposed to be, and can't get back. The solution is to
remove the entire shifter assembly. Now look into the gearbox.
There are metal bars running front to back. There are
notches in the bars that should line up to form a channel
from side to side. If they don't, then get a big
screwdriver and poke them around until they do. The channel
will line up with the notch in the reverse gear spring. Once the channel is lined up,
just reinstall the shifter. | | 4.4 | Why is my
t-case selector popping out of position (or stuck)? [Off-Road.com] Because the "sheet"
(as Suzuki names it, a piece that guides the transfer case
shifter) in the transfer case has worn out. Order a new one
and replace it. The part number is 29541-80051. | | 4.5 | Why is my
fuel pump leaking oil? [Off-Road.com]
[How
to replace it yourself] It's shot. And it'll leak a lot of oil, so keep a close eye on the engine oil level until
you get it replaced. | | 4.6 | Why
should I put a locker in the rear axle before the front? [Don
Schultz] There are a couple of
compelling reasons for installing your first locking type
differential in the rear axle first: 1) Much of a vehicle's weight
transfers to the rear wheels when driving up steep hills.
This places most of the burden for climbing traction on the
rear wheels. The shorter the wheel base, the more pronounced
the effect. Under extreme conditions you can't afford to
lose any traction on a back tire, even in 4wd. A good
driver, with a suitably equipped 2wd and locking rear axle,
can go places thought only accessible by 4wd. 2) If you are like most
recreational 4x4 drivers, you spend more time in 2wd on the
street than in 4wd off-road. With a locker in the rear your
vehicle benefits from the added traction in both on and
off-road service. Note: Please don't
misunderstand. I like and own front wheel drive vehicles
but... there's a myth floating around that front wheel drive
vehicles climb better than rear wheel drive vehicles. This
is only because the rear wheel drive vehicles that were
tested lacked positive traction (a locker) to both wheels.
The same laws of physics apply to towing. That's one reason
why rear wheel drive vehicles in general are used to pull
heavier loads than front wheel drives. Bottom line for 4x4'ers...
two lockers are better than one, but if you must choose,
stick it in your rear! |
