Guys,

I am going to replace the rear main seal in my 54 / 235 this week and I am fairly confident that that year still used the rope seal. I am not sure what year the neoprene seal is used on, but today I went to the local Oreilly Auto Parts store and gave them the fel-pro # BS5048 which is for the rope seal.

They had to order the seal in and when I went to pick it up, we opened the box and it was the neoprene seal. The instruction sheet inside the box talked about rolling the seal into the bearing cap and cutting off the excess which has to be rope.

I told the guy it was the wrong seal and he agreed. Another Oreilly employee said maybe Fel-Pro upgraded the seal. Well, unless I am missing something, I don't think the neoprene seal will work. I had him order another seal. Hopefully the right one comes in tomorrow.

Am I missing something here? I know it's been several years since I replaced a rear main seal, but has Fel-Pro really done away with the rope seal?

Thanks!

Kevin

I don't think most AP stores can get the rope anymore. Do a search on here about rope rear main seals and you should find a source. They are getting harder and harder to find.🛠

Don't waste any time on the Felpro seal, it will not work the way you want it to. Go online and purchase the Best seal. Summit Racing and Amazon carry them, along with direct from Best.

I believe 6100 is the Best part number.

That is correct, kthomas

Try to find it on Amazon or Summit (that is what/why I was asking Joe H).

It is available on eBay, and maybe elsewhere (like, Marx Parts LLC).

As Paul Harvey used to say, here's the rest of the story. Turns out someone at Oreilly's main warehouse in Springfield, MO. sent the wrong rear main seal (the neoprene one), which I suspected the minute it was taken out of the box. Anyway, they got in a Fel-Pro rope seal and I am returning it because I ordered the Best Gasket rear main seal # 6100.

With everything I have seen here and read, I think it is the best choice. Fix it one, fix it right!

Thanks all!

Kevin

I put a Fel-Pro neoprene seal in my 235 about 10 years ago. Touch wood, so far so good. A good trick I learned when installing the seal instead of having the joint at the 9 o'clock/3 o'clock position I positioned it at the 8 o'clock/2 o'clock position. Makes for a better seal. The main cap is 9/3 so by going 8/2 it eliminates a chance of leaking.

If any one is still interested I got one at NAPA last year, I think they had it in stock, if not it was the next day.
