在摩托车修理中,经常遇到火花塞螺纹孔滑扣的问题,对二冲程车来说,换一个缸头即可解决,因缸头价格低。但对四冲程车来讲,因此问题更换一个新缸头就不太合算。 为解决以上问题,我将滑扣的JH70车的火花塞孔改制成CY80车的火花塞孔,使用CY80车的火花塞,效果很好。 首先,在台钻上将缸头夹正,从缸头的内面,用直径13.75毫米的钻头扩孔,然后用M14×1.25的丝 In the motorcycle repair, often encountered spark plug thread hole slider problem, two-stroke car, for a cylinder head can be solved, because the cylinder head low prices. But for four-stroke vehicles, so the problem of replacing a new cylinder head is not too cost-effective. In order to solve the above problem, I will glide the JH70 car spark plug hole into CY80 car spark plug hole, the use of CY80 car spark plug, the effect is very good. First, clamp the cylinder head on the bench drill, ream the hole from the inside of the cylinder head with a 13.75 mm diameter drill bit, and then use M14 × 1.25 wire
