Timing Question about 5682s

Posted by patgreen On 2013/8/19 14:26:23

If you spend too much time on this site, you may recall that I have been having what appeared to be cooling issues on my 5682.

It now appears that the cooling issues are in the past, but some adjustment is needed for dwell and timing.

In the manual under specifications, timing is listed at 10 degrees BTDC, but in a service adviser engines before D-1834 should remain at 5 degrees.

Can anyone explain the why? If the distributor was improved/changed how do I tell which I know have? Or can the mechanic divine timing on his own?

According to SC 29-5, "the engine plant stamps a number on a milled boss at the right rear corner of the right cylinder bank. these numbers can be seen by looking upward at the boss, which is in back of the exhaust manifold." Would it be easier to pull the engine, or can this wretched number actually be read in situ?

Puzzled here.....
