Maintenance Instructions of SC27G Diesel Engine




In the part one of Shangchai SC27G diesel engine maintenance, we have already known how to st the detailed maintenance plan and task and methods of engine maintenance, such as checking engine periphery, checking fuel tank, checking air filter service indicator, checking oil level and so on. In this post, we are going to learn more instructions about engine maintenance like checking drive belt, cooling system, adding grease, belt tension and changing engine oil and oil filter.



5.3.8 Checking drive belt

Perform visual check on the drive belt everyday for any intersecting cracks. Transverse cracks along the width direction of the belt are acceptable, while longitudinal cracks (along the length direction) that intersect with transverse cracks are not allowed. If any wear or abrasion occurs, replace it.

5.3.9 Checking cooling fan

Perform visual check on the cooling fan for crack, loose rivet or blade bent or any other defect. The fan should be installed reliably. Tighten the fastening bolts or replace the damaged fan if necessary.

Warning: Damaged fan blade can cause serious personal injury. Do not pull or pry the fan, and do not rotate the engine with the fan.
5.3.10 Checking intake system

Check the intake hoses for any crack, as well as perforation, and clamps for looseness. Replace the hose(s) if any fault is found, and tighten clamp screw(s) if looseness is found to ensure the intake system free from leakage.
5.3.11 Adding grease

Add proper amount of sodium based lubricating grease in the small hole.
5.3.12 Checking belt tension

Check

Apply a force of about 98 N on the middle point of the belt span between the two pulleys with finger by pressing and pulling, and check the position change of that point. The change should be within 8-12 mm. If it is out of the range, make adjustment.
Adjustment

(1) Unscrew the tensioner nut and screw or unscrew the adjusting bolt to adjust belt tension.
(2) Tighten the tensioner nut t0 122-152 N*m.
5.3.13 Changing engine oil and oil filter

Warning: Be careful when changing lubricating oil and oil filter because skin contact with the hot oil or hot engine surface can cause scald.

(1) Don't stop the engine until the temperature of the coolant reaches 60, then remove the oil drain plug on the oil pan, scrap the washer and drain the lubricating oil.

Caution: Do not drain lube oil when the engine is in cold state at which foreign particles has deposited and attached to the bottom of the oil pan, and will not drain with the oil. When the lube oil is warm, foreign particles suspend in it and can easily drain with it.

(2) Clean the installation surface of the oil drain plug on the oil pan. Install the drain plug with sealant Tonsan 1567F and tighten it t0 60 -70 N*m.

(3) Clean the outside surface of the oil filter. Remove the oil filter with tool and scrap it. There are two oil filters (over the oil cooler on each engine side) and both two should be replaced at the same time.
(4) Clean the seal surface of the filter head, and there should be no old O-ring left.

(5) Do not fill the new filters with clean oil. Only apply a light film of Vaseline or clean lubricating oil to the O-rings on the new filters to form a lubricating film before installation.

(6) Turn the filter by hand until the O-ring contacts the sealed surface of the filter head, and further tighten it t0 45 t 5 N*m or 3/4 to one of a turn with tool.

(7) Open the filler cap (near the lower part of the cylinder block), and fill the engine with clean lubricating oil until the oil level is near the high level mark in the oil dipstick. The lubricating system capacity is about 65 L and oil pan capacity about 42 L.

(8) Start the engine and keep it running at idle, and then check the oil filter and drain plug for oil leak.

(9) Check the oil level at idle or low speed. If required, add engine oil until it is near the dynamic high level mark (the mark 2) in the oil dipstick.

(10) Install the filler cap and tighten it until you feel suitable.

5.3.14 Changing fuel filter (second stage)


(1) Clean the outside surfaces of the fuel filters (two filters). Remove the filters with tool and scrap them.

(2) Clean the filter heads and its seal surfaces. There should be no old O-ring left.
Note: There is two fuel filter, change them at the same time.

(2) Before installing a new fuel filter, fill it with clean fuel from the 8 peripheral holes. The fuel level should be 3-15 mm below the threaded hole. Apply a light film of Vaseline or clean lubricating oil on the O-ring on the new filter to form a lubricating film.

Caution: Do not add fuel from the central hole of the filter.

{4) Screw the filter by hand until the O-ring contacts the seal surface of the filter head, and further tighten it to 45± 5 N?*m or 3/4 to one of a tum with tool.

5.3.15 Replacing fuel filter (first stage)

The first stage fuel filter is also spin-on type. Refer to "Changing fuel filter (second stage)" for replacement procedure
Refer to the instruction on the filter for the removal directions of the filter and water container.

We supply multiple brands of generator set, such as: Cummins generator, Volvo, Deutz, Doosan Daewoo, MTU, Ricardo, Perkins, Shangchai, Weichai, Yuchai etc. The style of genset is varied, such as: container genset, trailer genset, portable trailer genset, soundproof genset, low noise genset, and silent genset, etc. Besides, we also supply design and construction of the noise reduction project up to the customer's requirements.

Guides to Clean VOLVO Diesel Generator Cooling System

VOLVO Engine Cooling System Volvo engine's internal cooling system makes sure the engine works at the right temperature. It is a closed system that must always be filled with a mixture of concentrated coolant and water in order to protect the engine against internal corrosion, cavitation and bursting due to freezing. Coolant of a suitable chemical composition must be used all year round. This also applies in areas where there is never any risk of freezing, to provide the engine of  diesel generator set   with full corrosion protection. The use of anti-corrosion agents alone is not permitted in Volvo Penta engines. Never use water alone as a substitute for coolant. The corrosion protection additives become less effective over time, which means that the coolant must be changed at regular intervals; refer to Maintenance Schedule. The cooling system must be flushed whenever the coolant is changed; Volvo Penta coolants have been prepared to work best ...
