Oil Pump

Share this page

The issue is whether the brand new ones are Chinese junk like so many replacement parts that I've had to toss in the trash. Original parts, if not worn out, are generally far superior.
With some parts its an annoyance. With an oil pump you may not know you've got a junk part until catastrophe occurs.
Thus my concern.

Yea that's a concern. Finding a trusted supplier is an answer maybe...and the old saying when purchasing.. pay enough but not to much..
 
With the Burman rotary-vane type pumps, the vane face condition, the body condition and free movement are most likely the main determining factors. Trash picked up from the sump can damage the faces of the vanes and the wall of the pump. There are no real clearances to measure because of the movable vane simply rides on the inside surface. As long as there is minimal or no scoring on these faces, the pump should keep working just fine. Make sure to pack the oil pump with a low temperatur type grease (vaseline, white-lithium, a very smooth, buttery type wheel bearing grease. Use just enough to get a good seal on the vanes so the spinning of the engine to get oil pressure prior to initial startup is minimized.

The Hobourn-Eaton or concentric types have been covered and the measurements are provided to give an indication of pump wear. While the measurements will confirm the condition of the pump, most pump wear is self evident by the scoring and scratching on the pump internals and the body. Obviously worn oil pumps reveal the wear easily. Those that have seen long service in a clean environment and have experience chronic wear (normal) need to be measured.

Thanks for confirming my suspicions about the Burman type pump, Mike. I knew if I waited long enough, someone would know the answer.
 
I'm up here in the hills of South Carolina where the internet needs directions to get to my house. Our broadband is kind of iffy. Some days better than others and I'm at the shop most of the nights after the day job and on weekends, so I use the nice fast connection in my cubicle during the day when I can sneak a minute or 30. The power company I work for hasn't made too big a fuss yet, so I'll keep posting while I can. Take care and I'll check in when I can and see what's of interest on the BCF.
