I haven't posted any progress in over a week because I ran into a couple of issues (not problems) with the ATI Super Damper (Part# 918039) that I was not aware of until now. Let me explain. The ATI Super Damper claims to use the OEM length retaining bolt. This may be true with the OEM crankshaft but not with the Kellogg stroker crankshaft I'm using. When using the ATI Super Damper with a Kellogg crankshaft a longer bolt must be used. I spoke to JDM who supplied me with the rotating group about this issue and they were already aware of this and had a solution. Matt (JDM's engine builder) recommended using an ARP 206-1001 bolt which is slightly longer than the OEM bolt or the ARP OEM replacement bolt. The F5RZ-6A340-B OEM bolt is on the left, The ARP 156-2501 OEM replacement bolt is in the center and the ARP 206-1001 bolt is on the right. You'll notice the ARP 206-1001, besides having a longer under head length, also has a 19mm 12 pt head. The head of the bolt is also slightly longer which is great because it gives you slightly more material for the socket to contact when turning over then engine. The 206-1001 measures M12 x 1.5 x 53mm
Now that I have resolved that issue, I proceeded with the installation of the ATI Super Damper. This damper requires a .031" washer (part# 954078 which is included with the damper) to be installed prior to installing the damper hub.
The hub is now pressed (not driven) onto the snout of the crankshaft. Note: ATI recommends using anti-seize on the snout of the crankshaft and ID of the bore of the hub to prevent galling. I used
Motorcraft XL-2 Nickel Anti-seize and Permatex 82180 Ultra Black sealant in the key way.
ARP 206-1001 bolt with the OEM washer was torqued to 105 ft. lbs. as per JDM's recommendation. If you look closely you'll see I sparingly used Permatex 82180 Ultra Black sealant under the head of the bolt and washer to prevent any oil seepage.
Prior to installing the damper on the hub be prepared to purchase a T40 Torx Plus socket (shown on the right). A T40 Torx socket (shown on the left) is NOT the correct size and will damage the countersunk fasteners. Here's the difference between the 2 sockets
PS: you do not have to purchase a $30 socket from Snap On (Part#
FTX40TPE) as I did. After doing a bit of research I discovered there is a much more economical and smarter way to purchase this tool. ATI sells just the T40 Torx Plus bit, (part# 918997) which fits in a 6 point socket, for less than $5 and it can be purchased through
Jegs,
Summit Racing, etc. or directly from
ATI.
With the correct socket or bit the damper can be installed on the hub using Locktite 242 (Blue - medium strength) as per ATI's recommendation.
The larger 12 pt. bolts are torqued to 30 ft. lbs. while the countersunk bolts are torqued to 16 ft. lbs.
None of these issues are difficult to overcome but if you need this longer 206-1001 bolt, be prepared to wait as only ARP had this bolt in stock. This is most likely due to the intended application of this bolt: 1.6L BMW Mini Cooper camshaft sprocket bolt
