I would have to see the rods to determine what is wrong, but I'm suspecting this bolt problem with the rods was caused by the same thing that got every other threaded fastnener in this thing..... stuck stripped and rounded off.
Dirty and dry and that's what your gonna get.
Clean and with the right sauce then there are no problems.
My left thumb is swelled up now because people don't know how to use bolts.
Bolt broke off inside dana 40 front axle housing. Flipped a coin on weather to set it up in the mill or carve it out freehand. Tails. Carved it out just fine with a carbide burr.
But the threads were about 35% damaged...because it had SAND jammed in there. So drilling it out for the helicoil I went for a ride a few times and my thumb bent the wrong way.
Maybe should have used a negative rake drill bit.
What I'm saying is the stupider the last guy was then the smarter you will need to be to salvage the situation. It's proportional.
HOPEFULLY someday you will build engines powerful enough and long lasting enough to need a steel pulley. |

The largest problem that I see is that if you have it on an engine that can go from idle to 7 grand in a split second the pulleys do not last long unless they have a steel hub. |
you can put a CR/SKF speedi sleeve on the pulley hub for the seal to run on. _________________ http://www.thesamba.com/vw/archives/manuals/jim_martin_engine_build.php

exactly. I did this on the crank journal for a crank gear on a TDI. Many miles later, and not a drop of oil has left the BSM cover.
Warning: Those speedi repair pieces, have a lip, which you may have to remove. they are also like $70 dollars. If you didnt balance the ENTIRE rotating assembly (with pulley), you may as well just buy a new one. _________________ -'85 c10 5.3 LS, 222 cam, long tubes, x pipe, 3 inch spin tech's

For example,
This
Fixed this
I had to remove the lip, and trim the length on the lathe. If you have to do this, put the sleeve over a socket of the appropriate size. make one if you have to. I trimmed a socket to size, slipped the sleeve over, and parted to length.

Way to get at solving the problem.
What cylinders and who's pistons?
I've been trying to find a set of 94 cylinders to fit my case and heads, formerly 2180. 92 TW cylinders.
The pistons are with DPR currently. _________________ I have learned over the years.

Your pistons must be an older set of CSP. The newest have the CSP logo printed on the tops.
Mine are JE b height. Grant rings.
So, you're using the AA 94 thin wall?
I see you bought a Stage II PP. Are you gonna run it? Or try the Stage I first and see if it slips?
I have been following this train wreck, Er forensic adventure, since you bought that thing. _________________ I have learned over the years.

Ah, yeah.. Take and feel the cool metal against my cheek..
Cylinders are just regular ‘ol 94s.
A Stage 1 and good dual-friction disc might have made more sense,
But,
This motor should theoretically drive through that setup.
So,
Since it all has to be balanced as a unit,
It makes sense to have a Stage 2 balanced up.
If it slips using the organic disc,
I can add a dual-friction without having to take the entire lower end in for a re-balance.
Plus,
The fancy disc costs more than a plate.
And my cable tube is already well reinforced in the tunnel.
Those pistons are indeed the ones.
They didn’t get logo’ed for whatever reason. _________________ Bus Motor Build

Mark, love ya man, but i disagree. I would use hastings every day of the week before using the grant, and if we are all being honest Hastings supplies almost every one of the ring companies. Obviously total seal does a good amount in house but I can tell you they are not making all of their rings. I have never had a problem with Hastings performance wise... although i have had issue with the wrong parts being in the box years ago. _________________ Schnell, SCHNELL!

So, i been chipping away at the 'ol Bomb here...
Ordered an AA VW-journal 82-stroke 4340 crank, but accidentally pulled-down the number for a 74...
We'll see how long they take to switch me out.
Shoulda just ordered an 82 and kept the 74 to sell.
Like many places, if there's not some money in it for them, they're not going to be in any kind of hurry..
My main man Jim kissed off the deck for me.
I just clearanced the sides of the inserts with a disc.
This after running them all the way home with a bunch of red LocTite..
Noticed he took just a minimum;
Says it cleaned up in about .003".
Measuring how far off-center the main bore is from the parting line,
There's between .0025 and .004" depending upon which end of the case.
When measuring how far from the deck to the parting line,
There isn't enough difference for me to be able to measure.
And it does follow the main bore crookedness to within a thou or two.
Jim says he won't set a stop and use it for both sides of a case when decking.
At least not with these Brazil cases - because of the main bore being crooked.
He says he'll measure how much it takes to clean up one side, then do the other the same amount after touching off.
If the factory case was done right he'll follow it,
But if it was wrong then the wrong will stay.
He's done enough of them that were right that he'll do it that way.
Interesting, eh?
Far as i can measure here with the bare case I'm good.
Once the cylinders and all go on we'll know for sure.
Just waiting on a crank...
Bunch of time to be spent filing high spots at the parting line.
Beat-ass old .060 case!
Had to Heli-Coil the 'first one you tighten' stud.
Got the cam bearings and all in, cam gear, etc.
We'll run it straight up for degreeing in for now.
Maybe an FK 45 should be advanced or retarded for turbo use?
Nice straight cam bores and perfect .001 cam bearings.
Turns like melted butter.
Nice to have one part right at least.

The three long 8mm case half studs, I torque them 3 pounds less than the rest. The extra magnesium under the stud expands when hot more than the 8mm stud stretches. Dan |
