crank bearing brace

[dzrtrataz]

If I decide to use the main bearing brace. What should be the clearance between the piston rods and the brace.

Thanks

Based upon what I've read and images shown on various STROKER threads /sites, that is to be two flat washers stacked to provide proper clearance.

0.100" to 0.200" should be plenty to allow for material stretch - two flat washers is about right for absolute minimum clearance.

Are you retrofitting one, or fabricating one?

The motor I'm using is from a 98 and already had it. So figured I use it since I have it. So I guess I will get some washers in the morning.

Thanks

sorry to steal the thread but im new here. i have a 92 block and is the main bearing brace a swap besides changing the main bolts and stacking the washers? thanks!

Correct btownxj.
QUESTION...
Not sure about this guys but are the later 4.0 oil pans a bit deeper to allow for the brace or are the pans the same? I DO know that if you use a 258 deep sump pan (and the corresponding pickup for the pump) the brace hits the pan you have to relief it with a BFH a bit.

[SilverXJ]

They aren't. And the fit varies between pan. I had to massage my pan a bit to get it to fit with the spaced out girdle, particularly at the front.

[SIXPAK]

On the front of a 4.0 pan SilverXJ?

[SilverXJ]

Yes, where it starts to curve up. That is where most of the bending was. IIRC someone on here has an image of where he heated it up bent the pan that way.

[SIXPAK]

Wow, would have not guessed that one. But then again I have never compared the two pans side by side either.

Bumping this as well vs creating new. Picked up a running 98 motor for 100 bucks ill be using the head on it and was curious about grabbing main girdle and using it in my 88 block? Outside of making sure there's clearence its bolt on and go right?

Also Chris? Silverxj..can you host those pics of your windage screen you did off the girdle?

[SilverXJ]

Using the girdle should be fine on your 88. Just check to see if where the main cap bolts hit the main cap are in line with each other. Yes, space the girdle up with some washers.

The images are in the build thread. http://www.jeepstrokers.com/forum/viewt ... 40&p=23474 But I'll put them here too.

Look like some 1/8"x1" wide strap? And some expanded metal? Would you do anything differently if you could do it a 2nd time?

[SilverXJ]

Yes, its 1/8" x 1", might be 3/4" can't recall. It is a form of expanded steel, but they are more like small directional louvers. I want to say its a Morso screen.

Alrighty. Looks like the stuff that's on my satellite in the back yard...the fiancé would kill me

How did you connect it all? I know you formed and welded the strap. I think I see a few tacks but it almost looks rolled at the edges? Am I seeing rivets?
Would you do it another way if you could?
