Oil pump bolt
I searched for info on this, and now I have more questions!!
1. do I need to pack the pump with Vaseline, and if so do I just pack it in the small hole (out let)? 2. I torque it to 65ft lb with locktite, dry, or oil on the threds. I did put a little oil in the pump to lube it up some. Thanks for your help. s/t

Re: Oil pump bolt
I take the 4 bolts out to take the pump apart. Soak it in new oil overnite. Put it together and on the motor. Just before i am ready to fire the fresh motor I use an oil pump primer to prime the motor till i have oil preasure and see oil coming out of the rocker arms.
I dont use vasoline at all. I put some locktite on the threads and torque it.

Re: Oil pump bolt

Re: Oil pump bolt
I didn't use loctite or soak it in oil, although now that I think about it I guess it wouldn't have hurt. Did it a year ago and haven't had any problems.

Lots of folks have different opinons on Loctite on the main bolts/studs and rod bolts - but it's not generally recommended. People do use Vaseline or ARP lubricant (with ARP studs/bolts only). |

Re: Oil pump bolt
I didn't prime it, but it wasn't a rebuilt motor. Are you supposed to prime it no matter what?

So just squeeze some in the out let hole and I should be good. So should I torque the bolt with dry or oiled threads? s/t

Yep, just squeeze it in the hole to be sure it's never dry. If it's an ARP bolt, then you should use ARP lube - anything else should be oil or Vasaline. You won't get proper torque with a dry bolt. Last edited by Billla; 06-03-2007 at 09:17 PM. |

s/t One other thing, there is no lock washer or anything on the bolt I took off. Should there be?

No lock washers on torqued fastners - the torque prevents loosening. Seems kinda scary...but it works. |

Re: Oil pump bolt
I respectuflly disagree. Any engine that's sat for any period of time should be primed before starting. It only takes a few minutes, and there's NO downside to doing it.
Most of what causes problems in crate engines, rebuilts, etc. is stuff that's dry on startup - dry cams, dry seals, dry bores, dry valves, etc. Make sure stuff is wet! Last edited by Billla; 06-04-2007 at 08:40 AM. |
