emanistan Posted March 23, 2020 Report Share Posted March 23, 2020 (edited) So coronavirus gave me a week off just as the weather starts to warm up here in Redding, to start putting my engine back together, then today this happened: IMG_0778 by emanistan, on Flickr And that put an end to my engine rebuild for the week. Thing is, that damned camshaft has been the bane of my existence. First I put it in too far and had to tap it back out once I realized what I'd done, then it wouldn't turn as well as it was supposed to, and then once I got it turning, I over-torqued one of the bolts on the locating plate and snapped it off. Luckily I was able to extract it and there was a 210 at my local Pick-N-Pull, so I spent 3 hours the next day stripping down it's engine for those bolts, went back home, and used the salvage bolts to put the plate on again before moving on to the pistons and the timing. This afternoon I was about to put the timing cover back on, but was worried the timing sprockets might not be all the way on the shafts, so I tapped down on the top sprocket with a hammer, and off snapped both bolt-heads again. Again; at least I was able to extract them. So where am I going to find another pair now? I think the main problem is my unfamiliarity with the torque wrench. I tried to go religiously by the specs in the shop manual, setting my cheap wrench at whatever numbers they gave. At first I blamed my wrench and went online to investigate better ones, and here I think I see where I went wrong: it looks as if most consumer-grade wrenches are not designed to go below 5 foot pounds. Maybe the expensive ones at the Nissan factory can go into the tiny fractions of a foot-pound, but I'm wondering if, for the average home mechanic, any number below five should just translate to :"until it feels tight enough".
