Where to buy??

[TonyTSi]

I was wondering if any of you DSMers out there could give me an idea where I could pick up one of the Concept Racing Crank alignment dowel kits? I can't seem to get ahold of Concept Racing themselves, and MachV is out of them right now. I have been searching performance shop websites and can't seem to find it, anyone got a clue?


Thanx in advance
Tony

6 or 7 bolt?

My understanding from the concept racing website was that it was the same kit for all 4G63 motors, but if there is a difference its for the 6 bolt sir.

What exactly is the purpose of this crank alignment dowel?
Thanks

nevermind...

The bearing cap on Mitsubishi 4G63 motors is held on by studs or bolts that penetrate through holes in the bearing cap. Those holes are machined larger than the bolt/stud diameter, and that can allow the bearing cap to shift under pressure. This shifting is a POSSIBLE explanation for the premature thrust bearing failure (or "crank walk") seen on some late-model 4G63 motors.

The Main Bearing Cap Alignment Dowel kit from Concept Racing tightens up those holes with precision-machined steel inserts. The kit is designed to be used with ARP studs when you are re-assembling the engine. The inserts are inserted into the bearing cap, then the studs then fit through the inserts, into the block. The result is a nice tight fit, with the bearing cap aligned and centered correctly, with no chance of it shifting around under lateral loads.

We're not saying this is a cure for crank walk, but if it were OUR motor, we'd use these inserts. It's cheap insurance against a problem that can cost thousands of dollars.

Kit includes ten specially-machined cylindrical inserts, and complete instructions. Fits all 89-99 4G63 blocks.

Do a lot of people use these?
Thanks

I might have a set laying around that I ordered a long time ago and never used.

If you still have them would you be interested in parting with them? Hit me up PM if you are. Thanks
