Clean the crankshaft, especially flush the oil passages with pressure oil, blow dry with high-pressure air (or air pump), and do not leave yarn hair when wiping. Clean the main Bare Engine, and clean and blow dry all the oil passages of the cylinder block like the crankshaft. Install the bearing on the Bare Engine, apply engine oi

(1) Before installation, check whether the gap between the Bare Engine end and the edge meets the technical requirements. When installing the old ring, install the ring groove according to the original cylinder number and original order. When installing the Isuzu Engine, special tools should be used. (2) When install

The reliability and durability of the work of Isuzu Engine should not be too large due to the gap between the cranks. If the gap is too large, the lubricating oil will flow out of the gap and the connecting rod mechanism will cause a large amount of oil leakage at the rear end of the crankshaft. ① During assembly, the t

Do not increase the high speed of Bare Engine without authorization. Especially in the absence of a tachometer, it is very dangerous to increase the speed of Bare Engine at will. If the Isuzu Engine is found to be overspeeding (measure the tachometer or hear a scream), the Isuzu Engine should be turned off immediately,

The force of the connecting rod is directly related to the speed of the Isuzu Engine. Generally, the design safety speed of small four-stroke general-purpose Bare Engine does not exceed 4000 rpm. Below 4000 rpm, the loads borne by Isuzu Engine parts are within the acceptable range. When the Isuzu Engine is overspeedi

Poor lubrication is the culprit for the breakage of the big end of Bare Engine. Due to poor lubrication, we can usually find traces of wear in other places of Bare Engine such as the inner wall of the cylinder. Common causes of poor lubrication include: lack of oil in Bare Engine, use of inferior engine oil, excessive tilt angle o

Faced with a small Isuzu Engine with a broken connecting rod, we must be full of doubts: What is the reason for the connecting rod break? How to avoid this from happening again? The damaged Isuzu Engine function "tells" us a lot of information. Just by observing the clues on the Isuzu Engine components, we can find the culprit for the c

① Apply a thin layer of engine oil to the piston pin. You should be able to push the piston pin into the bushing with your palm without a sense of gap, in order to meet the requirements of tightness. ② Apply some engine oil to the piston pin, put it into the Isuzu Engine, and clamp the piston pin on a b

When the plane under the Isuzu Engine is aligned with the direction under the blade, the ammonium cutting should be stopped. At this time, press down the small end of the connecting rod to make the Isuzu Engine take off the ammonium knife to avoid corners and flares. When the diameter of the reamer remains unchanged, re-hingin

The correct fit of Bare Engine can be achieved through processing methods such as reaming or boring of Bare Engine. Select reamer: Select reamer according to the standard size of piston pin, and clamp the reamer vertically on the bench vise. Usually, the blade is adjusted with one knife to expose 3~5mm of the plane on the Isu

When overhauling Bare Engine, the Isuzu Engine must be replaced at the same time as the piston pin to restore its normal fit. The fit between the outer diameter of the Isuzu Engine and the small end hole of the connecting rod should have an interference of 0.10~0.20mm to ensure that the bushing does not rotate during

1. Bare Engine have high processing accuracy: especially some small and medium-sized through holes, the cylindricality can reach 0.001 mm. 2. Bare Engine have good surface quality: the surface is cross-netted, which is conducive to the storage of lubricating oil and the maintenance of oil film. 3. Isuzu Engine have

Bare Engine is a precision hole processing process guided by the machining surface, under a certain feed pressure. The machining allowance is removed by the relative movement of the tool and the part, and its cutting trajectory is a precision hole processing process with a cross grid. Honing refe

In recent years, with the continuous development of the automobile manufacturing industry, the automobile and parts manufacturing industries have become the largest and most important customers of the tool industry. As the "heart" of the car, Bare Engine also play an important role in the processing of the whole vehicle, a

① Apply a thin layer of motor oil to the Bare Engine, and you should be able to push the Bare Engine into the bushing with your palm, without a sense of gap, in order to meet the requirements of tightness. ② Apply some motor oil to the Bare Engine, put it into the connecting rod bushing, and clamp the Bare

(1) Select reamer: Bare Engine select reamer according to the standard size of piston pins and clamp the reamer vertically on the bench vise. (2) Adjust the reamer: Usually, one cut is enough to adjust the blade to expose 3~5mm on the flat surface of the Isuzu Engine Yes, the future cuts will depend on the size

To better prevent the bushing from loosening, after pressing the bushing into the small hole of the connecting rod, the bushing can be squeezed outward with an awl to make the bushing fit tightly with the small hole. If the piston pin with increased repair size is replaced or the bushing needs to be repaired for other reasons, the bushi

When overhauling Bare Engine, the connecting rod bushing must be replaced at the same time as the piston pin to restore its normal fit.

Below 4000 rpm, the loads borne by Isuzu Engine parts are within an acceptable range. When the Isuzu Engine is overspeeding, these loads

1. Before starting the Isuzu Engine every time, develop a habit of checking the oil level. When the oil is insufficient, add the right amount of oil in time to prevent the Isuzu Engine from running out of oil. 2. Regularly change the oil of Bare Engine. Generally, Bare Engine need to change the oil every 50 hours. Because the oil used

If the piston pin with increased maintenance size is replaced or the Isuzu Engine needs to be repaired for other reasons, the Isuzu Engine should be machined. Make the piston pin and the Isuzu Engine achieve proper fit, and ensure that the fit clearance between the piston pin and the Isuzu Engine at room temperature is 0.003~0.008mm.
