Just got all the parts to put the pto back together on my White 2-105. Six new clutches, seven spacers. The concern lies with having a pto unit out of a 2255 sitting on the workbench. Both the hired man and I realized there was more room on the clutch pack for the 2-105 that for the 2255. About 1/8 additional spracing. We tried to put in another set of clutch and spacer but it was snug. I have an IT manual for the 2-105 but it does not state how many clutch and spacers should be used. There were 6 clutch and 7 spacers when it came apart. This is what the Oliver book says. Did White add a set or is the additional space normal? The depth difference was visible to the naked eye but now that I think about it, I have not rebuilt the Oliver pto yet. Maybe that's the issue.
