编辑同志:1983年,我们部队农场购进的一台新东方红—75拖拉机工作不佳,特别是自1985年以来,竟连续发生气缸盖裂纹的故障,而且裂纹处大都在固定的位置。对此故障,我们曾多次进行过分析、检查,试图找到并排除此故障,但都没有达到目的。望编辑同志在百忙中给予答复。此致敬礼 Editor’s Comrade: In 1983, a New Oriental Red-75 tractor purchased at our unit farm was not working well, especially since the failure of cylinder head cracks occurred in succession since 1985, with most of the cracks being in a fixed position. To this fault, we have carried out analysis, inspection many times, trying to find and eliminate this failure, but did not achieve the purpose. Hope editors comrades in his busy schedule to reply. Sincerely
