Chapter 38 Helping and Guiding
After Jiang Haiping returned home, life at the service station continued as usual.
The leaves of the loquat trees in the yard are a bright green. Every morning when Ah Guang waters the trees, he squats under them and watches them for a while, saying that the fruit is sweeter this year than last year, and it will definitely be even sweeter next year.
Old Fang squatted at the workshop entrance smoking and said, "You're always talking about loquats, more than you care about old parts."
Ah-Guang said that old items won't get infested with bugs, and he can't leave the loquat tree unattended.
The training course has been going on for almost a month, with students changing batch after batch.
Old Chen's brother-in-law has already learned to change the filter himself. After returning home, a fisherman surnamed Zheng from Zhoushan called several times to inquire about the quality of diesel fuel. Every time Captain Hong comes to the service station, he stands for a while at the entrance of the training classroom, watching Hong Xiaobing sitting in the back row taking notes.
Jiang Haiping called Ahai to the workshop entrance and said that this batch of trainees would soon graduate, and he would preside over the graduation exam. The exam would include both troubleshooting and practical disassembly and assembly, and after the exam, they would sign the training file.
Ahai nodded and said that the diesel engine for the test was ready, with three faults set in advance: clogged fuel injectors, clogged return oil filter, and stuck thermostat.
These three malfunctions are the most common problems fishermen encounter at sea, and they are topics that have been repeatedly covered in training courses.
After he finished speaking, he squatted down in front of the 6135 teaching machine and checked each of the three fault points one by one.
The old fuel injectors that Old Chen's brother-in-law had replaced on his boat came in handy. They were completely clogged with carbon deposits, so we installed them on the first cylinder and had the trainee remove and clean them.
The return oil pipe filter screen was half-stuffed with cotton yarn to simulate sludge blockage.
I removed the thermostat and used a wire to wedge a small piece of wood onto the valve, but the valve wouldn't close properly and the water temperature wouldn't rise.
He set up the faults, wrote down the location and standard troubleshooting procedures for each fault in a notebook, and handed it to Jiang Haiping for verification.
Jiang Haiping took it and read it from beginning to end, then said, "Okay, let's take the test according to this."
Then he asked Hong Xiaobing how his troubleshooting practice was going.
Ah Hai said that Hong Xiaobing can now independently check the high-pressure oil pipe and return oil pipe, and has practiced the thermostat fault several times. He can tell where it is stuck just by touching it.
The only downside is that the disassembly and assembly speed is a bit slow, and the bolt tightening sequence is sometimes messed up.
Jiang Haiping said that slow disassembly and assembly were not a problem, but messing up the order was a big problem. He told him to practice tightening the cylinder head bolts diagonally several times in the next few days.
Ahai said okay, turned around and went into the workshop.
On the evening before the practical exam, Hong Xiaobing squatted alone in the workshop, practicing disassembly and assembly of the 6135 diesel engine.
Loosen the cylinder head bolts diagonally, remove them one by one and place them on a tray, labeling each one with its position.
After disassembling and reassembling, tightening diagonally, the torque wrench clicked four times.
He put down the wrench, wiped his sweat with cotton yarn, and looked up to see Jiang Haiping standing at the workshop door.
"Brother Ping." Hong Xiaobing stood up, still clutching the torque wrench in his hand.
Jiang Haiping went over to look at the cylinder head bolts he had installed, ran his fingers around them, and said that the third bolt was tightened in the wrong order. It should be tightened diagonally first and then sequentially, and the diagonal direction was not right.
Hong Xiaobing looked down at the bolt and said that he was distracted when he was tightening it, thinking about the return oil pipe.
Jiang Haiping said that you can't be distracted when repairing a ship. Every bolt has its own order, and if you miss one step, the whole machine will be wrong.
Hong Xiaobing put the torque wrench back on the tool wall and said he would practice it ten more times before the exam tomorrow.
On the day of the final exam, the training room was packed with people.
The trainees took turns going up on stage, first to be tested on troubleshooting, and then on practical disassembly and assembly.
Old Chen's brother-in-law was the first in line. He squatted in front of the diesel engine, first listening to the sound, then feeling the pulsation of the high-pressure fuel line. When he found that the fuel injector was clogged, he used a wrench to remove it, clean it, put it back, and tested the engine. The smoke from the exhaust pipe was lighter.
The practical disassembly and assembly test involved removing the cylinder head and replacing the cylinder head gasket. He loosened the cylinder head bolts diagonally, removed the old gasket, placed the new one on top, and tightened the bolts diagonally. The torque wrench clicked four times.
Ah Hai watched from the side, checking off each item on the assessment form.
The third fisherman from Zhoushan, surnamed Zheng, was old and slow, but he did every step steadily.
When removing the fuel injector, wipe the sealing surface clean with cotton yarn, and tighten the wrench only after the threads are aligned when reinstalling it.
After reading it, Ahai wrote four words in the remarks column of the assessment form: "Solid feel".
Hong Xiaobing was last in line.
Jiang Haiping stood at the back of the classroom, watching Hong Xiaobing walk to the diesel engine.
He first walked around the machine, then tested the cylinder head temperature with the back of his hand, and then felt the pulsation of each high-pressure oil pipe.
When I touched the third cylinder, it stopped. The pulse was uneven. I shone a flashlight on the fuel injector connector and found a slight oil leak.
He removed the fuel injector and found that the sealing gasket was deformed. He took a spare gasket from his tool bag, replaced it, and tightened it diagonally again.
When the diesel engine was restarted, the exhaust smoke from the exhaust pipe stabilized.
Next, he checked the cooling system. The inlet pipe was hot, but the outlet pipe was cold. He removed the thermostat and put it in a basin of hot water to heat it, but the valve did not move at all.
After replacing the thermostat with a spare one, the water temperature stabilized.
The third problem was a clogged oil return line filter. He removed the filter, cleaned it, and put it back in. When he started the diesel engine again, the idle speed was as steady as a heartbeat.
Ahai checked off each item on the assessment form and wrote a line in the remarks column: "The cylinder head bolts were tightened diagonally in the correct order, and the torque value was recorded in the maintenance sheet."
This was the result of Hong Xiaobing practicing dozens of times. The night before last, he squatted alone in the workshop and tightened it countless times. After tightening it, he disassembled it, and after disassembling it, he tightened it again. The clicking sound of the torque wrench rang for a long time.
The exam ended, and all twelve students passed.
Jiang Haiping put the assessment forms into the training file and wrote the names of this batch of trainees and the graduation date on the cover of the file.
These are the first batch of trainees to graduate from the Moon Island Service Station training center. There will be a second and third batch in the future.
Wang Cunzhi rode his motorcycle over and took a copy of the training records to the county for filing.
He squatted at the workshop entrance and said that the province was very satisfied with the experience of the Moon Island training site, and the subsidy for the next training course was already in the process of being processed.
Old Fang took the cigarette out of his mouth and said that the training course should be continued by the younger teachers.
After finishing work in the evening, Jiang Haiping sat on the rocks at the entrance of the courtyard wall and flipped through the training files from beginning to end.
Old Chen's brother-in-law, a fisherman surnamed Zheng from Zhoushan, two young men from Hongjia Island brought by the boatman Hong, and several fishermen from the town on the other side of the river—each name had their assessment scores and practical evaluations recorded behind it.
Once these fishermen return to their boats, they can fix minor machine malfunctions themselves, and they won't have to drift at sea all night over a loose bolt anymore.
The service station repairs ships, but the training courses teach people. Every person trained contributes to the safety of the seas.
Lin Xiu'e brought over two bowls of fish ball soup and sat down next to him.
She placed one of the bowls on the rocks and said that Ah Hai wrote on the performance evaluation form today that Hong Xiaobing's work was solid and much better than when she first came to the service station.
Jiang Haiping picked up his bowl and took a sip, saying that he would let A-Guang give a lecture in the next training class. He had practiced welding basics for so long that he could train students, and Ding Haisheng couldn't always be the one to carry the load.
Lin Xiu'e said that A-Guang had a good memory and had filled several notebooks with records. Every time he taught new students to recognize old parts, he would squat down next to them and explain the model number one by one. The students understood better when they listened to him than when they looked at the blackboard.
The waves gently lapped against the stone trough, and the lights were still on in the kitchen. Ah Hai was practicing the bolt tightening sequence with Hong Xiaobing in the workshop, and the torque wrench made a soft click on the cylinder head.
Several water pumps and heat exchangers need to be disassembled and inspected tomorrow.
Jiang Haiping finished the last sip of soup in his bowl, closed his training file, stood up, handed the enamel bowl back to Lin Xiu'e, and then walked towards the workshop.
