Oil Pump DS Bearing Replacement?

[Clip]

hey guys, in the middle of disassembly and i take out my oil pump driveshaft to find this:

i can feel the ridges with my finger so it looks to be pretty deep. is there any way i can smooth this with emory cloth or fine sandpaper and keep it, or is there a way to replace it?

thanks!

A machinst's scraper would remove that if you're careful.
(I've seen more botched AUX shaft bearing installs than anything else come out of so called "pro shops" so I'm hesitant to have them replaced)

or if you real handy with a razor blade... then some emery cloth to clean up...
bearing looks fine... so i would just fix not replace....

or you could buy two new ones from napaonline, for $8.... and then install them yourself so you know there tight.

Not dissing Clip but if Pro's botch it what makes you think someone at home can do better? (not to mention the correct driver so you don't botch the job isn't cheap)

Most shops dont have a driver to fit the back one.. its to small....
I installed mine ... :}

are these just tapped into place? i think i'll try to use the machinist's scraper.

how'd you install yours hommer?

i had a "pro" shop install mine (only because they were suppose to set the clearance) on the last block we did, my dad did them. we used a axle nut socket, fits like a glove and never had any issues.

^ socket and extention...

When I had my shop replace them, when I installed the shaft it was too tight, the shaft wouldn't even turn. They were Toyota replacements. The shop had to open them up with a scraper. It sent chills down my spine when I watched him do it.

Are the replacements always tight?

AJ: As you found there's more to fitting them then just hammering them in but I guess I'm just being an old fart again :: IJ. ::

Is scraping them a normal way to fit them. I would think to prevent damage to the bearing that maybe taking a little off the shaft might be a better option?

 

[Rennat]

the ones i received were already 'fitted' according to my machine shop, or semi-finished he said... i test fitted them on the shaft before i brought them down to him and they slid right on. but i dont know about once they got pressed in. i didnt remember seeing any honing marks.


if you were to remove any material, it would be from the bearings as those are the replaceable items in this process.

Personally I'd Linish the shaft to suit the bearing after it's pressed into place.

Toyota have a "range" of finishing sizes so if you got a set of thick bearings and a block that was on the tight side of the spec you get the non turning shaft scenario, or worse a loose fit which becomes quite a large Oil Pressure bleed.
