First let me say thanks to everyone for there help with my other issues. Now I have one more... I just recently took alot of my parts off, cleaned and painted my block, manifold, adjusted valves, etc.
After I got it put back together I went to start it and I had trouble, I think my timing was out of wack.,,, got my timing pretty much set, and at times it will start fine other time, the starter will drag. While I had it running I took off my neg. cable off the battery and it cut off.. I pulled my generator off and had it tested ( it was rebuilt in Jan ) it tested fine.. put it back on, changed my belt,,, started fine... I let it run for a while and then cut it off and tried to restart,,, it would just drag.. i traced my grounds and need to replace my starter ground... If that doesn't do it I'm think about having the starter rebuilt.
By starter drag I assume you mean it acts like the battery is low? If so, here are some things that can cause that, aside, of course, from a low battery.
1. Worn motor brushes.
2. Worn motor bearings.
3. Loose contact on the solenoid or on the starter.
4. Loose starter.
5. Starter mis-positioned; shims: missing, or too many.
6. Bad solenoid (worn internal contacts.)
7. Worn bendix or armature shaft.
8. Bendix housing shaft bushing bad or missing.
9. Poor engine-body-frame ground.
10. Poor battery or alternator ground.
A cheap trouble shoot would be to take the starter to an auto parts store just to make sure it is ok before trying other fixes. Many around here will test a starter free of charge. If this is a replacement starter, make sure it is correct for the trans being used. Example: a starter for a 300-6 & 3 spd and a 300-6 & C4 are not the same, even though they both look alike and will bolt on the same location...
Thanks, I'm took it off last night to have it tested. I'm not sure what trans. is in this truck... It used to have a 3 on the tree.....now its automatic.
