Flywheel to pressure plate alignment dowel info needed.

[mrgoodwrench]

I bought a luk flywheel and luk clutch kit for my upcoming auto to manual swap. The flywheel has holes but no alignment dowels for the pressure plate. I contacted a few places and no one seems to have any. Contacted 1 luk retailer and he said they dont use them anymore. This seems odd every clutch i have ever done has had pressure plate alignment dowels and the the flywheel and pressure plate both have holes for them. Im having a difficutlt time finding them locally and cant find a listing online. I stopped by my local engine and machine shop (they also resurface flywheels) and they had nothing that would fit. Best i can see they are very close to 5/16 (5/16 fits with no wiggle but not press fit like it should be) My flywheel is luk part number LFW376 and my clutch kit is luk 04-170 anyone know where i can get dowels or a part number or exact demensions ao i can track some down online? Thanks mike

Flywheel for a 2 piece seal crank?

fwiw, the dowel should be in the crank

Flywheel for 1 piece rear main. The flywheel to crank dowel is in the crank like it should be what im looking for is the flywheel to pressure plate dowels.

Sorry I read that wrong. I’d have to go look at the flywheel I have under the bench to see if it has dowels in it

Thanks for the reply

I had to pull the dowels out of my flywheel when mating up my sm465 to an ls2, I just used ARP bolts that had a shoulder. No issues.

That might have to be my last resort if i cant find dowels

 

[Bent77]

Might be the best option. No dowels here

You do not need the alignment dowels. Most of the gm flywheels I have used never came with them. The ones that did come with them I had to remove them. For example, putting a early style sm465 clutch on an LS flywheel. The bolts will provide enough alignment.

Hmm interesting to hear people arent using them. I did already buy arb bolts.

I will say that some of the later engine OEM pressure plate bolts I have come across have been shouldered. But all of the older gen 1 stuff I have messed with have just been regular 3/8" bolts with split ring lock washers. I have always just used regular grade 8 bolts except for the LS I did, that got ARP because they are metric and I didn't have any metric bolts laying around.

As long as you have an alignment tool for the disc, just match up the bolt holes and be done.

I think i will just shove 3 pieces of 5/16 rod (fits very well) in the alignment holes during assembly so i know its all straight then remove the rods once i have the bolts torqued down thanks all for the responses
