Three goals for today: Template for oil cooler mount; Plastigauge the new bearings; and check the primary chains.
First, a template for the oil cooler mount. To be bolted to the stock horn mount and hanging down essentially where i was going to mount the cooler anyway. This is how the Phaedrus I cooler was mounted, and a tail hung down below the radiator to mount the horn. I think I saw a close up of Terry's that's how he did it as well. Might have been some one else. I'm switching from a frame welded mount, to maintain flexibility should I decide to upgrade the radiator later.
Next, we plastogauged the new bearings received last week. 2 greens and 3 browns. They were all 5 very consistent and slightly past mid-range for "standard" tolerance. Well below the max tolerance allowed. So they are a go.
Finally, I bought a new primary chain tensioner. Definitely needed, compare old with new:
Old:
New:
Besides the obvious lack of spring tension in the old one, you can see bits of the rubber wheel missing. Shot.
But I have this mental block on buying new chains if unneeded. There is a procedure in the manual for checking chains. If this distance measures less than 70mm then OK to use:
Both the original chains and the parts bike chains measure 66.5+/-. So safe to use. But what's unknown is what do new chains measure? If new chains are 65mm, I'll use the used chains. But if new chains measure 60mm, I'll buy new. Does anyone know? If I don't get an answer soon, I'll buy new, measure and add to the communal data bank.
Now I have a tank full of parts to clean. Then I can fit my cases in the parts cleaner for paint prep.
Good day!
