Hi all
Just wanted to see what sort of feeling others get when you install the rope seal , crank spins fine with out it and big ends have 2 tho clearense and little ends have 1 tho ,
My procedure as follows to install
Lossened the seal up by hand
Soaked in engine oil for like 2 weeks
Used a round bar and hammer to knock into block and cap
Trimmed block end flush to block
I left a very small amount hanging out of cap on both sides
Tensioned down cap and kept removing and trimming away excess
I've done this twice now and the crank has a fair bit of drag from the rope seal when it is all tensioned down , to the point I'm concerned about cracking speed when first started
Is there a spec on how tight it should be or is this something that runs in a little once first started , I would hate for it to burn it out and have to pull the donk out again , I also have the neo upgrade which I have not installed yet but would this be a better option and if so could someone point me in the right direction to install as there looks like you got to cut it to size as well due to to much over hang
It's a hn040

Rope is for boat anchors IMHO

Hi Nathan, I wouldn't worry, in fact I think it is a good sign. Other's have noted this also. Don't worry about Rodomo, he just hates rope seals. Not that I am a fan of them either....

is there some conversion available to a neoprene seal for an original rope seal block?

[dron]

As I renber GMH went from rope to a neoprene seal and then back to rope as they gave less trouble, At least on the V8.

 

Rope works well it just takes a little more work tio set up. By the way I have never soaked a rope seal in oil, they are normaly made with a graphite lube and do not need anything othar than a good ammount of oil on the crank when installing it.

 

Your install sounds about right if you have rolled it into the cap and trimed it a little high on the cap before installing. The crank is normaly a bit tight to turn but if you can not move it reasonably easiley with the flywheel (may need to bolt it on) I would be a little concerned.

I’m not 100 percent on this others might be able to confirm but it looks like it slots in the groove and you cut it flush on the block and cap end and add a little sealant at the cuts , it was funny tho when I stripped this donk it had a rear main out of a vn v6 , that’s what i traced it down too, there was no maching to the crank and it still hand the knerling a rope crank has , it still leaked tho lol, I’ve only ever Seen this type a seal in the 186 block , never a 202! Any ways there are mixed reviews on the neo seals as well , hopeful someone will post on how to do the neo seals as well here

I will give this a go , I’ve only got a couple bolts in the flywheel atm and I’m using a bar a touch long then say a standard 1/2 inch breaker bar . I was considering on putting the flywheel and starter on and zapping it quickly to see how it turned .!

Rope seals are usually a bit until you start them the 1st time.
