According to Nissan, that part is out of manufacture. However, they did a search for me and found 8 at a dealer in Tennessee. I was gonna get a few, but he said if I got all 8 I could have them at half price each so I got em all. So if anyone needs one I've got extras.

•SKF Oil Seal #550219 Partsamerica.com $22.99
Partsamerica no longer around... When's the last time you bought any part for a 1200 at Pep Boys or O'riellys? Haven't had much luck lately..RockAuto lists the wrong seal (for H190 and R180)I actually have 3 new crush spacers for the 145 diff, but was hoping to just replace the seal and retorque. Bad Idea?
Quote:
If you are replacing the pinion oil seal in an iron housing H145 then be prepared for a little bit of work.

Here's the proper procedure.

Jack up car & remove both rear axles.
Uncouple driveshaft & remove differential.
Mount differential in suitable stand & remove hemisphere & crownwheel assembly
Remove drive flange & extract pinion.
After cleaning housing, replace seal.
Fit new colapsable pinion pre load spacer & refit pinion.
Refit all other parts.
Check & adjust as necessary pinion depth of mesh & preload as well as pinion to crownwheel free play.
Correct as necessary.
Using new gasket, refit differential to rear axle housing.
Re-install axles & refit drive shaft.
refill diff with oil
Run car in gear on jackstands to check that all is well.

Lower car to ground & return it to service.

For alloy housing H145

1. Place car on jacks or hoist.
2. Remove drive shaft & drive flange.
3. replace seal.
4. reverse steps 2 & 1

Why don't you need to replace the crush sleeve on an alloy diff housing?

Thanks, but I'm in Los Angeles... Don't think I'll be walking into Bursons..

Does anyone know the differential pinion oil seal number for the h-145? I've got numbers of the seal but it doesn't translate into a part # that I can find. Plus a source if you've got one.

This is what that style air dam looks like on a coupe. They call it a 'spook'.........

I'm running 35 psi and only -1 degree camber for the street, but my suspension is all spherical jointed, so it doesn't distort much under cornering.

The flares are made for the 1200. The rears may fit on other cars because the shape is fairly symmetrical, but the fronts will only fit the 1200. I got them from Classic Datsun Motorsport In Oceanside California (near San Diego). You can see the wear on the R888's in the lower picture. That's after a year of hard street driving with a lot of really fast canyon driving and one trackday. Toyo seems to have developed an amazing rubber compound, they wear really well. The RA1 Proxes is longer wearing than the R888 (I had a set of RA1's on my 510 for three years plus 4 trackdays and then put them on my 620 pickup for a year and there's still a 'tatoo' of the tread pattern showing! After sitting in the backyard for another year, they're still not getting hard.), but the R888 is gummier. Both tires however don't seem to heat cycle at all, they never get hard and stay sticky all the way down to the cords. The R888 is also available in more sizes. The 225/45 R13 size seems to be made for the 1200. At just over 20" in diameter, I don't know what else you'd put a tire that size on except for a small '70s Japanese car. I really can't say anything bad about either tire. Just keep in mind if you try the R888, that Toyo recommends a higher starting pressure, and slightly less negative camber due to the sidewall construction.

They are excellent in the wet! I've yet to get the car loose. Better than the RA1's in the rain.

Been running it daily this way for about a year now with no wear issues. Just be sure to use Japanese wheel bearings, and not Chinese or India made ones. I had 185/60 13's on the front and 205/60 13's on the back previously. The 205's were too tall for the front and would foul on the drivers compartment. The 225/45's are an inch smaller in diameter and I get to run the same size all around which is good for rotating as the tires wear. Plus there's that phenomenal grip and the cool looking wide stance!
