Grandpa’s Blazer gettin fixed up…

Papa is fixing up grandpa’s ole Blazer
Also is it safe to pop off this cap clean it up and shoot into black paint? Was gonna paint the transfer case black and then clear coat the aluminum cases

Yeah, the area you pointed out could totally be drilled and tapped for a plug (and you could do that), but the designers must have settled on the fact there were already holes drilled in that lower region and didn't do that.

I think painting cast iron is a good idea.
 
Ok what is the correct part number for front seal for the th350 turbo 350K

What they gave me from the “book” is wrong…. Part # 9845. Not even the flange lip around it.

And the npo3 output to rear axle seal also anyone know???

9845 is the front crankcase seal for a SBC.
you need a 6712NA


try this for the transfer case; 9449

 
Thank you. So no one thinks I am totally lame; brought one set home that didn’t work went back to parts store they couldn’t figure it out

Called my mechanic to talk with the because I don’t know proper terminology I called it a front trans seal they had it listed as front trans pump seal IDK don’t look right in the pic

This gives me a place to continue on with getting the right parts…

These bolts (red circle) should be head on bottom and have a 1" spacer on frame side. The spacer help keep the bolts from breaking when you get frame flex.

Yeah I am not a fan of unknown used roller lifters, esp at $400. New couldn't cost that much more. Now if the lifter where in an engine I knew, with no failure and normal wear, I might reuse those.
I like that you have a K case th350 with the bell housing brace. There should two more braces that go to plates under the engine mount buckets, to flexplate cover. Don't foreget these when the engine get installed.

X2 . And do NOT put spacer tubes between frame and crossmember for anyone finding this later .

Haha and for the record, I put them back the way they were when I removed them. So?????

And looking at other sites many delete the spacers and just put grade 8 bolts w lock washers and washers????

I am confused now.

I am pretty sure up or down is the same, as long as you keep the spacers and the bolts don't stick out to low and get caught on anything you are fine
 
For reference
I believe this is in correct because it came out this way but looking online I see other variations on where the sleeve is located. Also there were no lock washers????

Bottom of 2nd pic is pass side.

From the factory, the bolt and spacer goes on top of the frame flange. Nut and washer on the bottom. This would be less likely to hang up on something off-road. functionally, it doesn't matter. The purpose of the spacer is so the bolt is long enough to act like a small spring when the frame flexes so you don't pop the heads off. I have had a lot of these without lock washers, but the split lock washer really doesn't work the way you would think. If you want a locking feature, new distorted thread lock nuts would be the way to go.

I am fairly confident they came from the factory the way he has them currently.

really ? I mean maybe, but it's kinda dumb to have them protruding down to get scraped on a rock. Yeah I know the crossmember is lower, but in the middle, so the bolts and spacer under the frame are low hanging fruit.
