I found the census very intrusive. Their lackeys that come to the door are worse than Jehovah's witless. I will never speak french. Ever. Refused to learn it when forced down my throat in school. Every time I pick up something to read the ingredients I get the french side. Shove your french up your bi-lingual.




#1505753 520 rear brake woes.

Posted by datzenmike on Yesterday, 06:40 PM

I can try and take a pic later.... datzenmike has me questioning how I installed my shoes on my 521.. the whole leading/ trailing thing. .. I also have a 520 rear axle assembly in my basement should be easy to pop the drum off and have a look and snap a pic....

 

Unless one or both were also replaced wrong. A 520 is old and has probably had several sets of brakes put on. And as they get older and older the owner starts to do the changing.




#1505650 timing specs (help)

Posted by datzenmike on Yesterday, 05:24 AM

All engines like more timing at idle, however, adding static timing will add to the mechanical when revved up. If the total timing is 34 degrees you are now at 38. These engines are dual plug they don't need that much advance because the fuel burns in less time. In addition, they are almost hemispherical combustion chambers that are very detonation resistant to begin with. It may be pinging and you may not notice it.

#1505582 Need help identifying Datsun diff.

Posted by datzenmike on 24 July 2017 - 07:44 PM

Axle length doesn't come into it. Do they have 6 or 4 lugs. 29 or 23 spline. Is the housing aluminum or steel. Scratch it with a screwdriver.

Confirmed.




#1505511 Need help identifying Datsun diff.

Posted by datzenmike on 24 July 2017 - 03:20 PM

Sure looks like an H-190 differential. That's a 190mm diameter ring gear.

 

 

 

Truck will have 6 bolt studs for the wheels, cars are 4.

 

Truck 29 spline, cars are 23. Some early Datsuns were 13 spline.

 

Roadster, 510 wagon and 520/521 trucks were usually aluminum case, maybe early '73 620. Steel after that.

 

 

The gear ratio is stamped on the outer edge of the ring gear. Example 37:9 is 37/9 or 4.11

Wheel bearings on the H-190 are not lubricated by the differential oil and are sealed for life and completely separate. If the differential is destroyed this does not automatically mean the wheel bearings are also suspect.

This is a lot of work. You will need to change the entire axle. Only use for this is a camper or carrying heavy loads. Either way, I don't think your box will clear the extra wheels and the brake shoes/bearings are different than the stock H-190 I believe.

 

 

Just saw you are in Montana. Land of the dual wheel Dodge/Chev/Ford diesels.

I used to have a '78. 

 

You sure it isn't a '79??? The '79 had the chrome trim inside the rubber of the opera windows and the drip rails. I can't make it out but the '79 had the radio antenna on the left side A pillar. A '79 model year, would be any truck with a build date after June '78. The build date is located on the driver's door jam sticker. The '79 also had front fender emblems that said DATSUNBY NISSAN . I don't think the '78s had this, mine didn't.




#1505384 timing specs (help)

Posted by datzenmike on 24 July 2017 - 05:28 AM

Z24 with idle at 700 is 3 degrees BTDC +- 2 degrees. Don't forget this is a dual spark plug head and the timing is very much less because of the shortened burn time.

 

This is a ported vacuum advance so at idle there should be none as the port is well above the throttle plate and reading atmospheric pressure. None of the factory service manuals mention disconnecting the vacuum line to set timing. Although there's no reason to (at proper idle) there is no harm in doing so either. Disconnecting the vacuum advance hose is a hold over from the 50/60s when intake vacuum was used. No, you don't need to plug the disconnected hose either.

There there... take your time and use big boy punctuation with your words so it makes more sense.

 

 

 

Did any oil come out with the 'spaghetti' ???  Low or lack of oil is the usual cause of noise and wear.




#1505248 Half Pint - Z22 swapped 510 goon

Posted by datzenmike on 23 July 2017 - 09:35 AM

Saw one where the crack was drilled out and threaded and a bolt threaded in, then another overlapping, and another until the crack was stitched up.




#1505234 81 datsun 720 4x4 fix up!

Posted by datzenmike on 23 July 2017 - 08:44 AM

Truck E or DE KA engine. Home made 1/2" aluminum adapter plate and Z24 carb and an L20B distributor and you don't even need to worry about needing a high pressure fuel pump, EFI wiring and sensors.
