L28 full rebuild assembly

P-series are Tri-metal bearings. They have a steel backing, copper middle and aluminum surface. They are capable of handling a higher RPM than the A-series and are better on performance engines I’ve read. The A series are all aluminum.

I think top layer in tri metal is lead or a lead alloy, not aluminium.

Did you ever get the crankshaft end play worked out?

Not yet, but I will before I move forward. I’ve been gone a lot for work lately. Dial Indicator on it way thanks to one of our favorite members CO who offered me one of his extras.

He gave me one too.  Great friend!  So obvious isn't it?

Haha!! Just trying to pay it forward.    :beer:

What's the prospect of all three of us having our new shiny motors powering our cars at ZCON 2020?

Maybe I’ll sneak in there too with a fresh motor - if I ever get the beast to stay together - lol

Yep! I’m in debt at ZCON for an undisclosed amount of beer though. I’m hoping he’s a lightweight

You guys will be humming down the road and with my luck my engine will blow up 1/2 way there.

Okay, I finally got around to measuring the endplay of my crankshaft. Work has been crazy busy but I got sometime today in the garage. This is the first time doing this so I hope I did it correctly. I’m measuring .003” of endplay on this crank. After that I pushed the crank as forward as possible and then torqued the main caps down to 35 ft/lbs. I made a video measuring the endplay. If you see something wrong let me know.
I’m hoping to get the pistons installed next week. Goal is to have the motor finished before Santa arrives.

Yeah, I would agree with that .003". What is the spec?

Books says .002” to .007”. I don’t understand the second part where is says limit is .012”. I guess normal is .002-.007. After .012 you have a problem?

Mine is .003”, on the tighter side but in the limit.

Amazon Prime = frequent flier points. LOL
Looks good!

We dumped Amazon but our planes are still packed to the seams. Once they started their own airline they became a competitor.

Thirded. (or fourthded?) On the low end of the spec range. What number was it your machinist recommended? I know you told me, but I don't remember what he said.

Glad the indicator survived the trip. Always a little apprehensive shipping measuring equipment.

And don't forget that you'll likely have to grind the ring gaps. Make sure you're ready for that!

So the machinist said he likes to see .005”.
The indicator worked great. I caught my 12 yr old son treating it like a pogo stick and gave him an earful. He was the cameraman on the video. He has zero interest in cars. I’m tying to get him to be interested in something other that anything attached to a screen.
He thinks the Datsun is really cool but he has no interest in helping me fix it up. I told him when I’m pushing up daisies it will be your car. When I first showed him the car It time he asked where the infotainment system was. Oh....geez!

right of passage used to be wheels, motorcycle at 15 then car at 16. I was outta there at 15 come home to sleep.

I guess the new right of passage is the latest x box or whatever, maybe I phones. Funny how that is. maybe each generation just needs something different unless they happen to be a throw back.
