502 harmonic balancer
Hi There,
i discovered an oil leak on my last run from the front left side of my engine, much more of a splash only whilst i was WOT. since it was the other side of the oil cooler and seems to be splashing onto my fuel filter i figure it might have been from the crank oil seal. after removing the damper to change the oil seal, i noticed that the part of the damper which fits into the oil seal seems a bit rough, so i guessed i should get a new one installed "since i believe was the reason of the oil seal to leak oil on high rpm" now! my local dealer does not have a damper available, however i managed to get hold of a damper 3963532 number embossed on the back of it, seems to be the right one however has a different number to my previous one # 10216339. has anyone used same damper ( 3963532 ) on a 502 mercruiser before? should it be OK? please help! |
3963532 is for a mark 4 454.10216339 is for a gen 5&gen6 454/502,they are different due to the difference in the back of the crankshaft.i would not interchange them.
|
They seem really the same, weight distribution and diameter.
Should I not fit it? |
If I remember correctly the gen 6 and mark 4 have a slightly different external balance to them. If your balancing your crank either will work, If your just bolting it on use the correct one.
|
I purchased new aftermarket harmonic balancers, to replace my GM/Merc external balanced units. I brought them to a shop that specializes in balancing, and had them weight matched.
|
The only available harmonic balancer I found is the 3963532.
Can I use it? What if I do? Any damage? |
