Spacer

Would a head spacer be needed for a 115mm longer Hotrod crank and 795M06600 Wiseco,s

As long as it's a stock stroke crank, no. 795 series is made specifically for the 5mm longer rod by moving the wrist pin location 5mm closer to the deck of the piston.

Why would the local stealer install this spacer with a stock stroke crank. The squish is more than 2mm as it makes

no marks on 2mm solder wire.

sounds like they are idiots. if they put in the right pistons there is no need for a spacer plate. id take it back to them.... or on second thought maybe not sense they dont seem to know what they are doing

[dajogejr]

I'm thinking I'd find a different shop.

The 2 mil spacer plate is for a 4 mil stroker crank, NOT a long rod setup.

 

Remove the spacer plate...and squish it back out. Good for you to try and measure squish. :beer:

Spacer plate removed. Pistons are knocking the head.

[dajogejr]

Take the whole thing apart....you'll have to look everything over. If you had more than 2mil of squish, removed the plate...and now they're hitting the head, something is wrong.

 

What kind of head is it?

 

Measure the thickness of the spacer plate, make sure it's a 2mil plate.

Stock head. 2mm spacer plate.

Something is not right. Read the numbers off the tops of the pistons.

Do they start with 513, 573 or 795?

 

If they won't touch 2mm thick solder, but you take a 2mm spacer plate out and they hit the head...something isn't right.

795M06600 on the piston and the crank Hotrod 4011 5mm Long Rod.

Get me a picture of the side of the crank..please.

[Sheesbest]

Do you want me too remove the flywheel and then take a pic of the crank.

[dajogejr]

No...after I posted that...I forgot it was all assembled...

If I could see the side of the web, I can normally tell by a good pic if it's a stock stroke or 4 mil crank.

 

That...of course would mean splitting the cases.

 

Which..I think at this point, you're gonna have to do any who. You have the correct pistons for a long rod crank.

From trying a 2mm piece of solder and not having it squish/smash at all with a 2mm spacer plate...that tells me it's not a stroker crank.

But you should be able to run a bone stock head (not shaved, decked, milled) with NO spacer and 795 pistons.

 

Are these cylinders ported? Is there any way someone decked the top or bottom of the cylinders?

And what thickness of base gasket are you using?

 

I would put the cylinders on, torque down and check the deck height.

(At the edge of the cylinder, how far the piston is down in the cylinder at TDC.)

Stock base gasket. The cylinders are ported, and I dont know who ported them.

Pics of TDC and BDC .
