ENGINE

.

Q. How do I set the valve lash for the mechanical rockers?
A.
Take off the valve cover.
Disconnect the coil wire just to be safe.

Method 1

Using a 21mm socket wrench, rotate the engine clockwise looking at each cam lobe.
Point a the cam lobe straight down, and adjust a tappet, do this for each one until you are done.
Set to .008 warm/hot
or
Set to .010 cold


Method 2

Using same socket wrench, turn motor clockwise and set to top dead center with piston 1 on compression stroke. you can check if it is by taking the distributor cap off and seeing if its on number 1

Rotate until cam sprocket is on NO 1.
Now check
INTAKE 1 and 2
EXHAUST 1 and 3
Set to .008 warm/hot
or
Set to .010 cold

Rotate the crankshaft 360 degrees so piston 4 (or your cam timing gear is on NO 3), is on the compression, you can check same as the first time with the distributor.


Rotate until cam sprocket is on NO 3.
Now check
INTAKE 3 and 4
EXHAUST 2 and 4
Set to .008 warm/hot
or
Set to .010 cold
put valve cover on.


Check it again at 15,000 miles

Q. How do I set the ignition timing?
A. Here are some helpful readings.

    Timing Belt Change
   Video on understanding how to time an engine

.

Q. What is the spark Plug gap supposed to be?
A. The gap should be .028 - .033

.

Q. What type Spark Plug should I use?
A. Any standard copper plug will do just fine. Dont buy into the hype that platinum or iridium is better.
     They last longer, but copper is the ultimate winner when it comes to conducting electricity.
     NGK BPR5ES
     AutoLite 64

.

.

Q. What degree should the timing be set at?
A. 6 degrees BTDC is what they come from factory set at. 
     If you want more power, increase it to 10-12.
     If you run a weber carb, increase it to 10-14.
     I would not go any higher than 14. 
    This is best done with an inductive timing light.

.

Q. What all can I shave or get rid of on the intake when I install a Weber Carb?

A. See Image
 

If you can't weld aluminum, do this.

.

Q. Can I use a 2.0 Head on a 2.2 Block and vice versa?
A. Yes. The heads are actually the same.
     What you want to pay attention to is the block, and use the headgasket that matches the block.
     This is due to the difference in oil restriction differences in the block.

.

.

Q. Can I reuse the head bolts?
A. Yes you can re use your stock header bolts.
     They are not torque to yield bolts and will not stretch.
     Many have re used these bolts without issue.

Q. Where can I get a genuine weber 32/36 from?
A. You can visit www.redlineweber.com and/or call their sales line at 1-877-405-4345 and place an order. This is the only way to ensure a genuine product and not a clone.
     For the 86-93 Mazda B2000-2200 you will need the K-675 that has an electric choke.
     For the 87-93 2.6 that is not fuel injected, you will need the K-610

.

Q. How do I tune my weber carb?
A. Look here http://www.redlineweber.com/html/Tech/carburetor_set_up_and_lean_best_.htm
    Also here http://mazdaminitruckin.com/files/weber/

Q. What oil should I use?
A. You really can not go wrong with any 10w30 or 10w40 oil.
     Many use either a high mileage conventional oil, some use Rotella 15w40 where its really hot,  or a synthetic like Rotella T6 5w40.
.

.

.

Q. My engine is ticking and making noise, is it the lifters?
A. If your engine is a 2200 it has hydraulic lifters and over time they wear out and will not stay primed with oil.
     If your engine is the 2000 it has adjustable lifters we call mechanical rockers.
     Most owners replace these after a while or they remove the rockers and replace the rockers with the mechanical adjustable tappets / lifters from a 2.0.
     When doing the swap, always use the 2.0 cam with the mechanical lifters and use the 2.2 cam with the hydraulic lifters. If you don't you will never get the noise out.
     It is a common misconception that a thicker oil will help with this noise, but thicker oils resist flow. Flow is what you want.

.

.

Q. What oil should I use after a rebuild my engine for break-in?
A. Its common to use conventional oil for break in like 10w30 castrol and then later switch to an oil with higher zinc content like Rotella T6 5w40 Synthetic.

.

.

Q. What is the break in procedure after I rebuild?

.

A. Warning: Have a fire extinguisher handy when starting the engine for the first time.
01 - Once the engine has been installed in the vehicle, double-check the engine oil and coolant levels.
02 - With the spark plugs out of the engine and the ignition system disabled, crank the engine until oil pressure registers and the gauge or the light goes out.
03 - Install the spark plugs, hook up the plug wires and restore the ignition system functions.
04 - Start the engine. It may take a few moments for the fuel to reach the carburetor, but the engine should start without a great deal of effort.
       Note: If backfiring occurs through the carburetor, recheck the valve timing and ignition timing.
05 - After the engine starts, it should be allowed to warm up to normal operating temperature.
      While the engine is warming up, make a thorough check for fuel, oil and coolant leaks.
06 - Shut the engine off and recheck the engine oil and coolant levels.
       This is a good time to change the oil as all the assembly lube has washed off everything and is not in the oil.
07 - Drive the vehicle to an area with minimum traffic, accelerate at full throttle from 30 to 50mph, this would be in third, then allow the vehicle to slow to 30 mph with the throttle closed.
       Repeat the procedure 10 or 12 times.
      This will load the piston rings and cause them to seat properly against the cylinder walls.
      Check again for oil and coolant leaks.
08 - Drive the vehicle gently for the first 500 miles (no sustained high speeds) and keep a constant check on the oil level.
       It is not unusual for an engine to use oil during the break in period.
09 - At approximately 500 to 600 miles, change the oil and filter and re torque the cylinder head bolts (if the gasket manufacturer recommends it edit: or you are reusing old bolts)
10 - For the next few hundred miles, drive the vehicle normally. Do not pamper or abuse it.
11 - After 2000 miles, change the oil and filter again and consider the engine broken in.
       At this point you can switch to a synthetic oil of your choice.

.

Q. Do I need a gasket on the oil pan?
A. No it is a machined surface and only requires Grey RTV or any oil resistant RTV sealant on both sides of the windage tray and then again on the oil pan lip.

SUSPENSION and DRIVELINE

.

Q. How do re-index the torsion bars?
A. Read here http://mazdaminitruckin.com/files/mods/Torsion_Bar_Re-Indexing.pdf

Q. What kind of lowering leafs springs so they make for our trucks?

A. None, absolutely none. Think of something else. Get lowering blocks, and remove some leafs. Tried and true. always works.

.

Q. What oil do I use in my Manual Transmission?

A. GL4 80w90 Gear Oil. Has to be GL4 approved to protect the brass synchronizers in the transmission so it shifts properly.
Many drain the old out and refill with Redline MT90 and it shifts like butter. It take 2.3 Quarts.

Q. Will the doors and glass from a short wheelbase fix an cab-plus model?
A. Yes the rear window and side glass, and the doors are the same on all styles of the 86-93 trucks.

.

Q. Can I remove the ABS (anti-lock braking system) and if so how?
A. Yes, it's pretty worthless anyways. There is a brain module under the driver seat, remove that.
     There is a pulsator on the passenger side frame above the axel.
     You can remove that and reconnect or add a new line to reconnect your main line to the rear brakes, re bleed the brakes and you are good to go.

Q. How do I add power windows to my truck?
A. Read here in the mod section. Power Window Mod.

Q. How do I remove the DASH?
A. See here http://mazdaminitruckin.com/files/mods/Dash_Removal.pdf

.

Q. I have a non-tach cluster and want to switch to a tach cluster...is it plug and play, or do I have to modify anything?
A. Almost always plug and play. Sometimes you have to add a wire for the clock. MAKE SURE you take the speedo cable out of the center hole in the dash and route it to the left of that bracket, or it will break.

.

Q. Do I need to paint my headers?
A. Yes is a good idea to sandblast or use aircraft stripper to take the temporary paint off the headers and repaint them using something like VHT ceramic header paint.
     Follow the directions on the can. 
     Some have used their own home oven to cycle cure the header paint.
     If dont correctly it will last many years.
