The housing performed as expected after installation, and Harold mentioned that fact to two neighbors while they stood at the grain elevator. One of those men had laughed at Jonah in Earl's salvage yard the previous winter. He did not remember the joke until someone reminded him, and by then it seemed less funny than he had expected. A few days later he drove to the Kessler farm with a cracked pump component and asked if Jonah would be willing to inspect it.
Word spread the way it always had in a rural county, slowly enough that everyone knew who had told whom and quickly enough that a reputation could change before its owner realized. Farmers discussed Jonah's work at fuel pumps, at church suppers, and while waiting for parts at the equipment counter. Some were skeptical because he was only fifteen, and some remained skeptical after seeing a successful repair because they had lost expensive machinery to bad fixes before. Jonah did not resent them for that caution; he understood it better than they knew.
He continued working on discarded castings even after paying jobs began arriving. Every time he repaired a useful part, Silas made him return to the scrap wall and study a similar failure that had gone wrong. Jonah sometimes protested that the old pieces were familiar now, but his grandfather would point to an overlooked feature or a previous note that deserved reconsideration. The wall was becoming an unusual kind of classroom, one where nothing was cleaned up merely because the lesson had become uncomfortable.
There were failures, too, although not always the dramatic kind people remembered. A damaged housing arrived with too much distortion around a critical surface, and Jonah declined it after inspection. A cracked mounting piece had already been repaired badly more than once, and the remaining structure could not reasonably be trusted under its intended load. He lost the income from both jobs, but he gained something more useful: the ability to tell a farmer that a part was unsafe without feeling that he had failed as a mechanic.
Dale noticed the change in the visitors to the shop. At first people had stopped out of curiosity, wanting to see whether the boy who collected scrap had truly repaired the International. By early summer, some arrived with written descriptions of failures and waited patiently while Jonah examined the damaged components. A man who had once smirked at the pile of broken iron now asked Dale how soon his son might be free to look at a transmission housing. Dale found himself answering with an unfamiliar mixture of pride and caution.
