The Spirit of Granny VI: Coming back together

Well I finally found some scraps of time over the last few weeks to put this bottom end back together. I didn’t document the process that well but as you can make out from the presence of pistons above I’m a ways along.

This feels good

so fresh

Setting the main bearings in felt good. I test-fited and plastigauged everything and it was nearly identical to how I found it- well within spec. If I hadn’t needed cam bearings (and the necessary trip to the machine shop) I could have gotten away with the old ones. All for the best I suppose. The mains are so overbuilt in these. Half of a truck V8 I’m told.

One of the good things about putting it back together is getting rid of all the parts lying around the workspace. Maybe I’m the only one that feels that way.

I used Permatex assembly lube for the bearings and cam and regular motor oil for the bores. Deves Rings cautions against synthetics and who am I to doubt them so they got 10w40. The Permatex sure is sticky.

Speaking of pistons they were in great shape in terms of land wear so all they needed was a groove-cleaning with a special tool that I happen to own and touch up to be down to nice carbonless alloy.

There. That wasn't so bad, was it?

Now on to rod bearings and rings. In short, I put them in. Sorry- not much for pics.

The worst part of this is fussing over ring end gap. Even though Deves indicates a tighter spec than Volvo, the bores were so un-worn that I had to take a little off to achieve a happy minimum. Tedious. Then more fussing about ring clock position but I think I wound optimal angles. You my fair reader will never know.

Alright then. Don’t forget the spacer ring! In went the Woodruff key and that was that. More to come soon.
