Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 There are LEFT and RIGHT squirters.........if installed WRONG.....they will miss the piston BOTTOM with the squirts of oil. The head of the bolt is a RETAINER that retains a SPRING the LOADS a SMALL PISTON inside the bolt. These parts are MAGNETS for small particles of metal and will cause the piston to STICK OPEN allowing oil to pump FULL TIME. Link to comment Share on other sites More sharing options...

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 You can see the piston thru the "window". Again....it is spring loaded. When oil pressure reaches a certain point (don't ask me) the piston raises and oil is pumped to the "INJECTOR". Here's something to think about........They don't squirt oil until you reach a certain pressure........however if they stick open you are bleeding oil pressure at low RPMs. : Link to comment Share on other sites More sharing options...

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 Blow air thru them, poke the piston in, let it pop back. Blow the spring hole out as well. Play with them. The piston should open about 30-35 psi. Test the spring tension in all of them. Compair the tensions, they should all be the same. You want the squirters SUPER CLEAN! NEVER REUSE THE ALI. GASKETS! The Squirters MAY be a reason for LOW OIL PRESSURE! Link to comment Share on other sites More sharing options...

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 Run a paper clip down the injector to MAKE SURE you have ANY METAL that might be stuck in the squirter removed. I have seen these COMPLETELY PLUGGED UP! Link to comment Share on other sites More sharing options...

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 The large "masses of metal" on both ends and 2 in the center are called "COUNTER WEIGHTS" Note the HOLES drilled in the counter weights. They "BALANCE" the crank and a PORTION of the rods. Link to comment Share on other sites More sharing options...

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 A close-up of the "BALANCING ACT". DO NOT STAND YOUR CRANK ON END. That is one tuff CRANK. But if you stand it up..........you'll KNOCK IT OVER and YOU CAN BEND IT. 88-89s have a dowel pin sticking out of the back. Treat your crank like it is made of GLASS.

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 Not many cranks are "CROSS DRILLED" from the factory. This is an old "RACERS TRICK". Thanks Mr. Mitsu, but when used with GROOVED MAIN BEARINGS, you are pumping alot of oil OUT the mains, which STARVES the rods UNLESS you have a DAMN GOOD OIL PUMP!

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 Notice the oil hole is "CHAMFERD" from the factory. This provides a WIDER displacement of oil across the bearing. The rods do not have as much CHAMFER. Link to comment Share on other sites More sharing options...

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 Oil provided to the main JOURNAL (via the hole in the main "saddle" thru the main bearings) which is drilled to the "ROD PINS" (only one hole). Link to comment Share on other sites More sharing options...

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 That BRASS RING and SMUDGE on the left is not part of the crank.........it's from the BEARING. Famous 88 Mitsu screw-up. Link to comment Share on other sites More sharing options...

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 The area between the "PIN" and the "THRUST SURFACE" is called the "FILLET". It MATS with the CHAMFER on the SIDE of the rod. (see rod pic) Those TWO surfaces along with ROD CLEARANCE deside HOW FAST oil is ALLOWED to escape from the bearing. If oil is allowed to escape to FAST, you throw out TOO MUCH OIL. This reduces oil pressure and spins oil right at the pistons, which can cause the engine to BURN OIL.

Professor Quest Posted November 23, 2004 Author Report Share Posted November 23, 2004 This FILLET will need welded and REGROUND if it was a ROD PIN, however it's a MAIN JOURNAL so that surface does not contact anything. So it's good to go. Link to comment Share on other sites More sharing options...
