Hey guys
Im in the process of rebuilding a 202 and am putting the rear main rope seal in.
Now im having issues with the crank being very hard to spin once i torque up the cap. It works fine with all other bearings being torqued if the rear isnt in so it seems to be the rope seal binding.
Ive tried a few seals and they all seem to do the same...almost like they're all too thick and dont compress down enough.
Anyway has anyone got any tricks to get these bastards in and able to spin the crank without needing to swing off it?
Cheers.
Rope seal installation tricks?

Binding is normal, but by the sounds of it I would try tapping the rope a little harder into the groove with something like a round bar & hammer, working your way from one end to the other. There's plenty of tips hiding here on the forum & everybody does something differently, but it has to bind otherwise it won't seal.

Have you compressed the new seal into the groove using the special tool?. Not just a simple matter of drop the seal in the groove put the crank in, caps on and torque it all up. And yes the seal should offer some resistance to rotating the crank.

Yeah ive tapped it in and rolled it in. I understand there will be some binding but this seems a bit much...seriously need to put nearly all body weight on it to spin it.
I tried tapping it in more but the seal started to come apart...the rope threads started coming apart into strands.
Can excessive binding cause issues with the crank or will it wear the rope down enough that it loosens a bit?

Used another seal after the one disintegrated and it was tight as too. Still couldn't get it squashed enough.

Watch the video above a couple of times. That's the way it's done, the right way.

Make sure you don't leave the seal too high when you cut it, if the tails are too long it will make it very tight to turn.

I tried 3 rope seals until I gave up and put the neoprene version in. No leaks and no hassles. This was on my 308. I have done sixes before but the v8 had me stumped.

I rebuilt a 3.3 a couple months ago, and did the conversion, easy as no leaks, no excess crank drag, available on eBay

Done many as I'm sure most guys on the forum have, the vid posted is very good, follow it to the tee and she'll be fine, but do not underestimate the importance of soaking the seal in oil, personally I soak em up to a week, even tho they are graphite covered you still need to soak em
