Starter's spinning a plenty, but I've never had to "spin/grind" it in such a
manner before; 'shouldn't hafta spin/grind it in such a manner, and I DON'T
grind on it. After it warms a bit with additional glowing or by Mother
Nature, it starts with the usual short touch of the start switch.
You're right, it should start like it always did before. BTW, new glow
plugs would not have impeded starter.
'Haven't noticed any compression "puffing" around the plugs; yes, I've
looked and listened; 'don't see/hear anything unusual.

Get the starter draw tested. Sounds much more like a slow starter to me,
unless you have serious compression leakage around those new glow plugs
it should start like it did before.
Don't wait until it locks up....

Several months ago, I installed 6 new glow plugs in the SDL. Since
then, when its cool, below 50F or so, I have to glow it for 3 or 4
30-second cycles to start it without "grinding" starter. Glow light
gives normal indications, fuse is good/new (yes, it really is - good
power (12v) on both sides of fuse), relay clicks at 30 seconds,
continuity check of all plugs is good. 'Does same way with another good
relay. Plugs are obviously heating some -' just takes longer/several
times when engine is cold. When it starts, all cyls fire evenly with
nice, smooth idle. 'Seems that when it gets warm enough to start, all
cyls have warmed evenly. 'Just realized something I haven't done yet -
check voltage at each of the 6 relay pins during the 30-second cycle.
Always before, 'cept when plugs are bad, it started with just a touch of
the starter switch to START.
When I replaced the glow plugs, I did not ream the holes; suppose carbon
build-up is keeping the plugs from heating as rapidly or as well as it
normally has? 'Spose my need for additional glowing is due to carbon
build-up?
