Re: CD-11’s compression issue

[skanders01]

So, time for an update for all of this issue’s followers.

1. Using my corded drill (850 RPM) I was able to get the last of my three rebuilt 5.5’s started and running. Like the others, it did not want to idle down below the "shift" point on the tiller position band, but I will worry about that common issue among all of them when my garage thaws out.
2. Borrowed a loan-a-tool compression tester from AutoZone. According to that gauges readings (if we are to believe that gage; I know it is a loaner probably rode hard and put up wet) my gage (hoses, fittings, and all) is reading around 10PSI low. 30-35 came up to 40-45 for the CD’s, the 6R79E that I am sprucing up to sell this spring read in the mid 50’s, and my 40 HP came up to 90/90. All readings in a 30 degree environment and no additional lubrication in the cylinders beyond the residual oil from their last run.

So, from here, when it warms up, I will borrow another compression tester from a neighbor who is currently out of town for a third opinion. Will also fix whatever the heck is wrong cheap but new compression tester in the warmth of my basement!! Also need to finish working on my fantasy of a control scheme to operate the three I choose to tripe up on my FD-6 (that is also awaiting warmer weather to get spruced up.)

Not a resounding definitive closure here, but progress is acceptable. If I we ( 😀 ) had completely resolved/repaired the issue I would have to go out to find more trouble to shoot!

My thanks again to all of the effort on my behalf. Promise to send an update and pictures in a few months.
