How interchangeable are 318 harmonic balancers?
Ok, so,........I'm baaaaaack! (And given my day at the office today, I wish like he** I wasn't.)
I ordered a new balancer from Summit Racing a couple/three days ago, and it showed-up today. Before I even installed it all the way I did a TDC test and checked the timing marks. Everything looked great, so I bolted 'er in, and did it again. Twice. Both times I got very similar results (albeit different marks on my tapes, obviously), and here's a shot of the second test (pay no attention to the "x" line):
That TDC mark is da** near perfectly centered when I measured it out: 7/8" both ways, right on the nuts!
So everything was great, right?
Nope.
Turns out the bolt holes for the pulleys in this new damper are equidistant from each other, but....well....
Here. See for yourself:
The damper I bought is supposed to fit a '68 to '72 318 engine (I used a Dart as the Model on Summits site), and this one is a '71, so what did I do wrong?
(Reminder, this is a 1971 VG Valiant from Australia, RH drive, water pump dumps on the right, and the TC marks are on the left side, on the cover).
Here's what I bought (and I'm sorry it's sideways):
I doubt I can return it, as it's been installed, but now I don't know what to buy.
Can anyone direct me to the right part this time?
(Also, I may have a VERY lightly used 318 damper for sale soon, if anyone needs one.)
Thanks in advance, people. I'm going to slink-off and lick my wounds for the evening.
Signed,
Frustrated Jim
P.S. The original damper still looks good, and I don't see any cracks in the rubber ring, but here's proof positive that they can slip and still look good.
