посадочные диаметры

В последнем предложении ссылки, приведенной Олегом, речь идет, как я понял, о горячей посадке дистанционного кольца 3-4 на этот самый кольцевой выступ - "snap". А диаметры этих выступов суть посадочные диаметры, которые, конечно же, подлежат обязательной проверке при ремонте.

Кстати, дистанционное кольцо 3-4 лучше было бы назвать проставкой 3-4. По крайней мере, так это было принято в ЗМКБ "Прогресс" им. А.Г. Ивченко. Я просто это подзабыл и не сразу вспомнил.

диаметры соедининений и монтажных отверстий

предпологаю, от английского использования snap as in "snap in place" - т.е., вставить на место.

Удачи!

диаметры упорных колец

This disc has a snap, which is a circumferential protrusion about one third of the distance between the bore and the rim of the disc. It provides a surface which mates with the spacer-3-4 which connects the 4th Stage LPC disc and the 3rd Stage Fan disc. An inwards radial load is exerted on the snap by the spacer-3-4, which has a slightly smaller diameter, and it is assembled using differential heating before being bolted together.
