Standard rebuild with ARP head bolts

[Neal]

Question(s)....My crank wouldnt spin smoothly after torqueing the rods....its has new bearings...new rings...but it spins smoothly without the rods being torqued...aaaaarrrrrrrrrrrrrrgggggggggghhhhhhhhh..

any suggestions would be great

cheers

 

[IJ.]

Did you plastigauge it Neal?

 

[Neal]

no i didnt...but i got my machine shop to order the bearings
cheers

 

[IJ.]

Were the rods resized after the bolts were replaced?

 

[Neal]

i had a rod knock on rod 1...but its the standard bolt...my thread heading supposed to read ARP head bolts apologies.... i had the rod with rod knock machined...n asked the machine shp guy to order the bearings...

 

[IJ.]

Which shop did you use?
(I trust my guys 99% but still Plastigauge to confirm their work)

 

[Neal]

its in burwood conmakee somthig likr that

 

[IJ.]

It would be worth Plastigauging them but I'm guessing it's going to be too tight to try and run.

 

[Neal]

yeah it is too tight. i wouldn run it. how to i resize the bearings...

 

[Neal]

i think he gave me all the bearings the same size...

 

[IJ.]

What brand bearings did they supply?

 

[Neal]

ACL bearings

 

[IJ.]

In the past I've resized bearings by hand but you'd be stripping the top breakin coating off that ACL use so I can't recommend doing it.

I'd plastigauge it then take the crank, rods and block back and have them recheck the tolerences and correct it. (it's a fairly simple Linish job for them)

The Plastigauge is so they can't say it's ok without touching it.

 

[Neal]

i took it to the machine shop today it turns out my rod one is out of wack...this is after they rounded it for me the first time i went there and said its fine..so in search of another rod at the moment....

 

[IJ.]

Neal: Bugger I chucked out like 3 full sets not long ago....

 

[Neal]

Mate...no way...i cant believe you chucked it..Do you know of anyone who might have one

cheers

 

[IJ.]

A mate is dropping in shortly I'll ask if he has any spares.

I sold him my Prepped stockers out of my old dyno mule so he might have some.

Can't they resize the dud?

 

[IJ.]

Neal: He has a full set out of a 29,000 KM 7M how does $150 for the full set sound?

 

[Neal]

how do i kno its only done 29K...anyways how does hundred buks sound like

 

[IJ.]

I can take a pic of the speedo

I assembled his new motor and yes the car only has 29K on it!!

Just asked and he's cool with $100 if you pick em up
