ARP Part Number For L28 Flywheel?

I just looked in my ARP catalog. No listing for Datsun Nissan flywheel bolts. Sorry.

 

I did find in the ARP catalog that the Toyota 3SGTE engines utilize 8 flywheel bolts, M12x1.25x1” long. That is the same dimension as the Datsun L-series Flywheel bolts. This ARP 8 bolt kit part number is 203-2801. On paper it looks like they might work, though I can not condone the use of another flywheel bolt not intended for this application due to possible safety risks.

 

 

Here is a complete list of all Datsun/Nissan ARP hardware as my catalog shows. (shameless plug). These can be ordered through Rusch Motorsports as well.

 

 

 

 

Here are all the ARP listings for the L-6 engines;

L24, L-26, L-28

 

Main studs 202-5406

:iagree:

 

Yasin,

 

I am running the Toyota ARP flywheel bolts as Paul mentioned on my OS Giken setup. Same thread as Datsun works great.

Hi Paul,

Do you know if ARP now makes 10mm studs and 12pt nuts that would fit the FI intake. I also tapped the head on the outside exhaust flange for 10mm so I would need six if you could get them.

 

Thanks Jeff

Jeff,

I couldn’t find any 10x1.25 mm studs, or “any” 10mm studs for that matter in the catalog. ARP does offer various metric bolts. 6x1, 8x1.25, 10x1.25 and 10x1.50. The 6 and 8 MM bolts come in the following lengths…

12, 16, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 90, and 100mm lengths.

 

The 10mm bolts come in 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 80, 90, and 100 mm lengths.

 

All bolts are offered in either hex head or 12 point, Black oxide or stainless. Wrench sizes for the 6mm bolts is an 8mm wrench, for the 8mm bolts is a 10mm wrench, and for the 10mm bolts, a 12mm wrench.

 

Hope that helps,

Paul

Thanks Paul,

I got the 8mm stainless studs a long time ago when ARP started doing the import stuff. Somewhere ARP found me stainless 10mm 12 point nuts, but they had no matching Stainless studs.

I have to use 10mm studs for the top of the intake flange, as I have angled the runners up relative to the head and bolts will not fit in the holes without hitting the runners (does that make any sense?) Oh well I have ugly black oxide studs I will be stuck with for now. Thanks again for looking.

 

Best Regards

 

Jeff

FYI to update the post, ARP now offers a "KA24" Flywheel Bolt Kit with the same under-head grip length as the 3SGTE kit listed above. The kit only has the six bolts for the Nissan Application, instead of 8 for the Toyota.

 

P/N 102-2802

 

They also have a listing for RB26 FW Bolts with under-head grip length of 1.180", handy if you have bottom tapped your flywheel flange bolt holes and want an extra 0.180" thread engagement, or have some desire to use a hardened clamping washer so your nice soft aluminum flywheel doesn't stand such a chance of embedment and loosening of the bolts due to shock and vibration (HINT HINT!)

 

Here's the 2014 Linkey:

The matching washer to go with the ARP RB26 flywheel bolt (arp #102-2801) that Tony D mentioned is 

 

ARP part # 200-8710, you must order 6 of the washers.

 

Note: The inner diameter chamfer on the washer goes against the head of the bolt.  If you do not do this, the washer may cut the head of the bolt off.

 

I have not tried this yet, so I do not know if the clutch will clear bolts with washers under them but I think it will work...Ill try to post more when I get it together.

 

Thanks Tony.
