3JH2 Series Maring Diesel Engine  Inspection of fuel injection pump

Yanmar Engine Diagnostic Service Tool Software

(1) Inspection of plunger
1) Thoroughly wash the plungers, and replace plungersthat have scratches on the plunger lead or are dis.
colored.
2) The plunger is in good condition if it slides down smoothly when it is tiited about 60. Repeat this several times while turning the plunger. Repair or replace if it slides down too quickly or if it stops part way.

(2)Inspection of delivery valve

Yanmar Heavy Equipment EPC 11.2009

1) Replace as a set if the delivery valve suck-back collar or seat are scratched, scored, scuffed, worn, etc.
2) The valve is in good condition if it returns when released after being pushed it down with your finger(while the holes in the bottom of the delivery guide seat are covered). Replace if necessary.
3) Likewise, the valve should completely close by its own weight when you take your finger off the holes in the bottom of the delivery guide sheet.
NOTE: When fitting new parts, wash with diesel oil and perform the above inspection.

(3) Inspection of pump
1) Inspect for extreme wear of roller guide sliding surface. Scratches on the roller pin sliding surface are not a problem.
2) Inspect the plunger barrel seat.
If there are burrs or discoloration, repair or replace as this will lead to dilution of the iubricant.

(4) Inspection of fuel camshaft and bearings
1) Fuel camshaft Inspect for scratches or wear of camshaft, deformation
of key grooves and deformation of screws on both ends, and replace if necessary.
2) Bearings Replace if the taper rollers or outer race surface is flak-
ed or worn.
NOTE: Replace fuel camshafts and bearings together.

(5) Inspection of roller guide assembly
1) Roller

NOTE: Replace fuel camshafts and bearings together.
(5) Inspection of roller guide assembly
1) Roller

For Yanmar Diesel Engine Agriculture Excavator Tractor Marine Generator Diagnostic tool
Replace if the surface is worn or flaked.
2) Rolter Guide Replace if the outer roller pin hole is extensively worn or there are many scratches.
3) Replace if the play of the roller guide assembly pin/roller is 0.2mm(0.0078in.) or more.

4) Injection timing adjustment boft Replace if the surface in contact with the plunger side is unevenly or excessively worn.

(6) Inspection of rack and pinion

1) Rack
Inspect for bending of rack and wear or deformation of fit with pinion.
2) Pinion Inspect for wear or deformation of fit with rack.
NOTE: If the tooth surface or sliding surlace is not in good working order, rack resistance increases, affecting the condition of the engine (rough rom, over running, etc.).
(7) inspection of plunger spring and delivery spring Inspect springs for scratches, cracks, breakage, uneven wear and rust.

(8) Inspection of oil seais Inspect oit seals to see if they are burred or scratched.

(9) inspection of roller guide stop Inspect the side of the tip, replace if excessively worn.

(10) Inspection of O-rings Inspect and replace if they are burred or cracked.

Yanmar Maring Diesel Engine Disassembly of Fuel Injection Pump Guide

  Yanmar 3JH2 Series  Maring Diesel Engine Disassembly of fuel injection pump guide  

 

Yanmar Engine Diagnostic Service Tool Software

 When disassembling the fuel pump, separate the parts for each cylinder and be careful not to get them mixed up.
Be especially careful to keep the plunger/plunger barrel, delivery valve/delivery valve seat and other assemblies separate for each cylinder (the parts of each assembly must be kept with that assembly and put back in the same cylinder).
Preparation
1. Wash off the dirt and grease on the outside of thepump with cleaning oil(kerosene or diesel oil) before disassembly.
2. Perform work in a clean area.
3. Take off the fuel pump bottom cover and remove lubri.
   cant oil.
4. Turn the fuel pump upside down to drain fuel oil.

(1)Loosen the nut with a box spanner and take it off, holding it with the hole in the fuel coupling ring or holding the coupling with a vise and take out the governor weight assembly.

(2) Remove the fuel feed pump.
NOTE: Do not disassemble the fuel feed pump. See in-
structions for fuel feed pump for details.

(3) Remove the fuel pump side cover.

(4) Turn the camshaft until the roller guide is at themaximurm head, and insert the plunger spring support plate in between the plunger spring washer B lower side) and fuel pump unit.

NOTE: If the camshaft does not turn, put double nuts on the end of the cam shaft or remove the coupling.
(5) Remove the camshaft wood ruff key.
(6) Put a screwdriver in the two grooves on the camshaft bearing holder mounting surface, and pull out the cam-
shaft bearing hotder.

Yanmar Heavy Equipment EPC 11.2009

NOTE:
1.Be sure not to damage the oil seal with the threaded part of the camshaft.
2.Be careful not to loosen the shims in between the pump and bearing holder.

(7) Turn the fuel pump upside down, move all the roller guides to the plunger side, and then put the pump on its side. Turn the camshaft to a position so that none of the cylinder cams hit the tappets.
(8) Put a plate against the governor end side of the cam-
shaft and lightly tap it, and pull out the camshaft and drive side bearing.

(9) Remove the roller guide stop.

(10) Use a hammer handle or the like to push up the roller guide from the bottom of the pump, and remove the plunger spring support plate.

NOTE: The plunger spring may make the roller guide and plunger, etc. fly out when the plunger support plate is removed.


(11) Remove the roller guide.

https://isuzumachinerepair.blogspot.com

NOTE: When you stand the fuel pump up, all of the roller guides drop out at one time. Therefore, first remove the stop bolt for one cylinder at a time, and then the roller guide for each cylinder-continue this process.

(12) Remove the plunger, plunger spring and lower washer from the lower part of the pump.

NOTE:Keep the parts separate for each cylinder.

(13) Loosen the small screw on control pinion.

NOTE:1. Check to make sure the match marks on the pinionlsleeve are correct before loosening the small screw on the control pinion, as the pinion and sleeve come apart when the screw is loosened. If the mark is hard to read or off center, lightly inscribe a new mark. This will serve as a guide when adjusting injection volume later.

(14) Remove the control pinion, sleeve and upper rest.


NOTE:
Keep parts separate for each cylinder.


(15) Remove the con: rol rack stop boit and remove the rack.

NOTE:Be careful not to lose the spring or rest on the control rack.

(16) Loosen the delivery valve retainer stop bolt, and remove the dellvery valve hoider stop.

(17) Remove the delivery valve holder.

(18) Remove the delivery valve assembly.

NOTE:1. Be careful not to lose the delivery valve pack-
ing. delivery valve spring, delivery valve stopper or other small parts.
2. Keep the delivery vave assemblies for each cylinder clearly separated.
(19) Take the plunger barel out from the top of pump.
