After a few weeks of futzing around, I finally fixed the broken air cleaner bracket in my 83 CD. It was truly a miserable job. In all seriousness, I had less trouble putting in new axles then changing out this piece. The engine vibrates terribly at idle so next stop is a valve adjustment and an engine shock. I think the mounts were done a few years back but they'll be checked too.
Now fo the lesson learned, you do need a swivel joint on the 13 MM socket to get the bottom bolt out. Even with that it was a bit tough. I ended up using an impact wrench swivel and impact 13 MM socket, not the impact wrench itself though. The impact swivel is just a lot more even in how it tramsmits torque. I used the 3/8 drive size. I WD40'd the swivel and worked it around some and it with the socket went on the hard to get at bottom bolt and with that I was able to remove this bolt and get on with the job. Use a lot of patience doing this as rounding off the bolt would be pretty sickening. It went back together OK but all-in-all it was not a satisfying job since it took all day and I'm sure with the shaking motor it just going to break again soon.
Does ANYBODY know the real part number for the gasket that is used on the oil feed tube to the turbo, the one you have to take apart to get the bracket in and out? I ordered a pair by part number but the pair, labeled TURBO DRAIN something GASKET were too big, right shape but not the right part. I'll have to call the folks here.
Thanks for listening.
