Default What is the best way to install an oil pickup ?

Itīs a zz502 engine with this oil pan kit: http://www.summitracing.com/parts/NAL-12495360/

I canīt seem to get the pickup to enter right in the oil pump. Iīve tried the fastener and a hammer trick, and think that would work if I can just get it to enter right..
Should i feeze the pickup or what ?
The oil pump is still on the engine btw, should I remove it ?

Yes take it off the engine. Disassemble the pump and work on just the cover. I would try disassembling the check valve, and putting the cover in the oven at about 350 degrees, put the pickup in the freezer and then try tapping the pickup in. The other alternative, is taking a pipe nipple of sufficient size, and make a notch in the end, so that it fits over the bend, and seats on the ridge of the tube and tap it in that way. Maybe someone has a picture of the "tool".

You don't need to disassemble the oil pump to install the tube! C'mon!! Use a wrench and tap it lightly into place. The oil pump is not made of plastic. Then weld it to the pump Quickly and not too much heat!

Remove the pump from the engine and make a support for it so that it sits level on the workbench. I use 1 piece of 2" X 4" and other lumber scraps to make the support. Either buy or make a tool so that you can tap the pickup in place by putting pressure on the ridge, as stated in a previous post. Warm up the pump with a heat lamp or shop light for several hours and put the pickup in the freezer. Also look closely at the pump inlet and the pickup for any dings or gouges in the mating surfaces and fix them first. Parts should go right together if these steps are followed.

You think I've never done that cub bear with boxing gloves routine hammering on an end wrench because I posted a pump and screen manufacturers recommendation? C'mon!

That's how I've always done them but I'm not going to any more! If that's how you do them, great. But not me, not any more anyway.

I thought he made pretty slick work of it myself.

Have you ever seen a main cap with the o/p mounting thread boss broken off? I have never broken one but evidently some guys have because I recollect a thread from a few years ago where somebody was asking how to repair one. And those pumps are softer than all getout as I ran a 3/8 npt tap into one for a contraption I was building a few months ago and I could not believe how soft it was.

Makes me wonder if the "new-style light pump housing breaking" internet rumor might not have a root cause of somebody hammering a pos pressfit screen into an installed pump. I'm tellin you the stuff is like butter it cuts so easy. Whether or not the softness relates any at all to the pump breaking whotahell knows, but I consider them dainty and don't intend to harm any more of them if I know of a better way.

And the reason I know the tool is backorder at summit is because I have a 5/8 on backorder, and I have a little tinkertoy engine that will sit there and wait on the damn 20 dollar tool because I intend to do my jokey-ass pos press fit pump screens the right way if I'm doing an engine that doesn't merit a bolt on screen. And they don't all "tap in lightly" either. Yeah I've had some go fairly easy but most of the ones I've done have been pitiful tight. 6 thou interference according to the mfgr video. 6 thou interference is insane tight and the only reason they go together is the tube is thinwall. If that suction screen was made of thicker wall tubing that 6 thou interference would not go together.

Got it in tonight

Left the pickup out in the snow for half an hour, screwed off my oil pump and put it in front of my propane heater.

I still had to hammer it pretty hard with a wrench and hammer,
but h... yeah I got it in there and tachwelded two small spots, one on each side. I was such a tight fit so I can`t believe the welding will do any good, but at least now it`s there for safety. I didn`t remove the spring inside the oil pump, can`t imagine those two spots will ever create noticable more heat than racing hot oil will do.
This has really been bothering me, and I couldn`t been more happy with the help from you guys !
