Aligning Dampner Plate To Fly Wheel

Getting ready to reinstall fresh rebuild in boat. My question is what is the best way to realign the dampener plate back to the flywheel so the transmission will slide into bell housing easy.

Thanks George

Eric, I feel that 49 is asking about the alingnment of the damper to the flywheel and not the trans to the damper.

49, The damper plate is bolted to the flywheel with shouldered bolts. IE: the threads don't go all the way to the head. The shoulder matches a close tolerance hole in the damper and the counterbore in the flywheel. To get the splines to line up, a little twisting of the trans may be required.

I just put a new damper in mine. Put the damper on with the bolts finger tight. Put the trans on and tightened two of the bolts as much as I could.. Pulled the trans off and then tightened all of the bolts. Tightening all of the damper bolts through the starter hole would be tough. I thought about doing it that way but did not have the time to make the correct tool to do it.

I received my new damper plate from Skidim today when I did a fit check and the damper plate didn’t fit the flywheel like the old dampener plate did. I have a PCM 1.23 transmission; the rib it heads doesn’t fit in the counter bore of the flywheel. Also the OD of the damper plate is larger than the DIA. the starter ring is pressed on. Skidim recommend bolting the plate to the flywheel and allow the sheet metal to flex approximately ¼ of an inch. Would his cause any problems for the damper plate or transmission?

Thanks George

The springs of the damper are not touching the flywheel they sit in side the counter bore of the fllwheel. It will slide on the spline of the transmission ok. I am reinstalling a rebult 351w in the boat. The file size of my camera is to large to up load to th

Only two of the files you sent me will open??

do you have the correct face facing the correct direction? Looks a little big and might have issues with the starter.

well you could mount the flywheel to the crank with the dampner plate mounted to it and mount the starter and check out any clearance issue you might have even turn it over if you want just leave the coil wire off so it doesn't start and have someone else run the ign switch while you what the starter engage.

Check for the proper splines on the trans.
This is a Sachs brand damper. I feel, and Eric has confirmed, that it is better built and heavier duty that other brands. The one shown has 7 different mounting hole patterns so they claim it will fit almost anything. Some trimming of the OD may be required on smaller flywheels. The link I provided is cheaper than Skidim.

Eric, you were the one who mentioned the triangular damper! I did know they have different splines for different tran's. I didn't know that you had to go through PCM for the 7 spline though.
