The pickup is not on a tube - it's on the oil pump. Not separable. The B230 oil pump is designed to be used on a slant. I have no idea how the B20 oil pump fits. One of those things that we need to look at. We should grab Paul's if he's willing to part with it, though. I'm sure there's lots of hopup pieces for the B20 pump, right?

Coburn, didn't you use a b21 oil pump on your engine?

Found this on the web...

Quote:
WHAT IS NEEDED: If you want to install a B21 in an 1800, like I did, you need one very important
piece for the engine. It is Volvo p / n 1266945-3 the pipe that delivers the off from the oil pump to the
engine. It was used in the early B21's as these oil pumps are basically a B20 oil pump with a different
pickup screen. The availability of these pipes may get scarce, so if you want to do this kind of conversion,
scrounge up a pipe now! This pipe allows you to use a B20 oil pump on the B21 and then you can use a
B20 oil pan on the engine. I have a jig for making up more engine mounts, get in touch with me if you're
interested in purchasing a set


What do you know about this Craig?

Is it not that freshly rebuilt one that I had picked up? Or did that go somewhere else? I just seem to remember a lot of stuff painted red on it and the blue silicone. Looks good though

If I'm not mistaken, that's the b21a I bought off of you Andy. Its on loan to Dale for the mockup.

If I'm not mistaken, you're both not mistaken... :lol:

Paging Coburn... Did Dierdre tie him up in the basement again? Or maybe that stack of Jaguar parts collapsed on him... :shock:

Coburn Performance to the rescue. Despite all popular prattlings about me being tied up in the basement or lodged under a mountain of car parts, all untrue (or at least that's what I'm forced to say). I am, in fact, paying a certain amount of attention, but am spending most of my evenings working on my cars and my days are so busy that I haven't been able to check the board.

On with the answer. I did use parts of a B21 oil pump with the B20 bottom section on my engine. That's what I was able to scrounge from Greg's parts pile and my collection of pumps. They are physically the same, only the pick-up is different.

Now for the bad news, almost any B20 pump you get (or B21) will have a ball bearing check valve and the spring that controls the release pressure will be warn on one side due to it rubbing on the housing. It is a faulty design and the cause of most pump failure. Good luck finding the spring (Olof maybe? Valentine?).

You can get the high pressure spring from IPD, but that is only for the later B20 pumps with the plunger style valve (and if you find this style of pump, I've got the high pressure spring). Volvo then went back to the ball style valve with the B21 (early is the same as B20- not sure about later). It's just a hair longer (about 0.050) and has the same diameter and same wire gauge.

Anyway - If I was doing this over again, I'd just get a new pump. Why screw around with a used oil pump on a new engine? I spec'ed my pump and relapped the face of the pump (I've done it a thousand times with hydraulic pumps when I was younger) to get the groves out of the pump that I used and the gears were checked and were right on spec. That's why I didn't go with the new pump (that and sometimes I pinch the odd penny).

Coburn out.
