good evening all, a former member of this board and i have a mutual friend who has recentlly dismantled a redstone for inspection and corrective work. at first glance, it looked like a turn of the century hit and miss that was unearthed in a sub-way dig. after extensive mecanical scrubing,touch up grinding and trip to the after hours soak tank, things looked quite promising. problems so far was cam cover missing the outboard bushing and no provision for controling cam end thrust. after turning and pressing new bushing into cover,we discovered .030 thou runout at end of camshaft. as it turns out a spacer bushing between the cam gear and the injection cam was not sized and broached to fit over the shaft and 8mm key, but a piece of cored stock that measured 1 .183 was used to go right over the shaft and key and was over tightened . the new spacer was made 1 .023 id 1.500 od and .640 wide (.040) less than oem to allow the inj. pump cam follower to track c/l of cam. also the key that was fit was at least .080 to long and was bottoming out between end of key broaching on cam and washer under retaining nut. i thought it of some import to mic up all parts for width at 120 degrees that make up the cam stack before assy. the inj cam had a nasty burr that had to be corrected on the surface grinder. the washer under the retaining nut was disgarded because of the loss of .040 in stack height exposed the unthreaded portion of the shaft so a stepped washer was made up w/ .100 step to make sure of no false tightening. will have to adjust some bolt holes in cover after final location and fit 2 3/16 dowel pins to keep it from creeping around. last thing check the gov fork on the shaft. we will re drill and oversize. will have to make new pin because the orig pin is ruined by poor pinning of the fork and lots and lots giggle. all else looks pretty good. too bad you could not get the bare castings so you could let them season then finish them stateside . if you get one of these engs cleaned up and detailed, it WILL go the distance, everything is big,thick and heavy. he should have it together soon . all in all, was much better than earlier anticapated. blink
