Hi, I have the new modern seal and there is an inner ring that appears to be directional, does the beveled side inner seal fin point toward the radiator or toward the crank case?

Just a tidbit of food for thought.
When installing a modern sprung seal, the spring ALWAYS goes toward the liquid you want to keep in!You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!Comment

Question, is the new modern seal the best way to go ? PatModel A's and of course the famous AA'sComment

Not for me. I like the rope seals just fine, and have never had one leak.Originally posted by pAAt View PostComment

My rope leaked the install before the current one which is the modern seal. Rope leaked like a seive, modern seal is dry as a bone. If you install the modern you need to put some rtv around the outer part of the seal.Comment

Tom: what rope seals do you use, the white teflon ones? Ours are leaking on a new motor with good pulley. Maybe break- in needed? Are the modern seals neoprene, nitrile, etc? We removed from a motor an older neoprene that was not very effective.Comment

Yes, I think the last one I used was pretty white with a black rubber in the center. The older ones I used were more grey colored without any center rubber, and they also worked fine.Comment

Hi all, Just a follow up on the problems with the 2 pc. broken crank pulley I was dealing with in late October.
I finally got the new (screw together pulley) installed after checking all the main bearing clearances while I had the pan off and reinstalled the new "modern front seal" as per DaWizards instructioins and followed the "leakless oil pan" instructions to the T and I'm delighted to report no leaks at, so far, after about a 100 mile of test runs and a few hard pulls, on some very long steep hills in the area, over a few weeks period.
Weather has taken a turn for the worse so I am grounded for a while right now.
Thanx so much to all who replied with their valued input. I'll keep the forum updated if anything changes on the front seal results. Many thanks again!!Comment

I purchased the McBee A-8926902 rear seal for the Detroit with Teflon. It comes with a plastic sleeve and am not sure of its purpose.
Is the sleeve used in a new installations or is it for shafts that have a grove warn into it? If you do use the sleeve, how is it installed?01-13-2022, 02:11 PM -
Found this photo on the net of a modern type seal. Just found out it is a modern seal with an alum. outer jacket sold by Specialty Motor Cam ( replacement shocks, etc.)....11-18-2017, 02:00 PM -
I'm installing rear wheel hub seals right now and I have a question. I searched the Chassis and Powertrain tech areas, but no luck. Maybe I'm too stupid to do an efficient search??
How deep do the seals sit?
Seams simple enough... most cars have a ridge to seat the seal against, but not in this case. This makes for no hard stop for the seal and I'm concerned that I'll install the...05-23-2018, 05:49 PM -
Which is better...The Front Crankshaft "teflon coated rubber rope" packing...OR this new Front Crankshaft "one piece nitrile seal"?
I have always used the rope in the past.
Thanks.

I am having constant problems with leaking front seals. Are the currently-available non-asbestos half-seals undersized? Am considering using the "modern" seal. I assume that I do NOT have to remove the oil pan, although of course the timing cover and pulley have to come out. Am I correct? Ed10-15-2020, 10:35 AM -
We used the new teflon type rope seals on a new motor with about 100 miles on it. Nice drip which runs down the oil pan front and no leaks elsewhere. It was put in according to all posted info. and greased very slightly. The leak is blackish oil. Is this normal with this type of seal. We ran out of the old style rope and the 2 piece pulley looks ok. Any suggestions ?...10-23-2017, 10:23 AM

I figured out the seal but which way does the bushing go in? Dimple towards the front or rear?02-16-2019, 01:15 PM -

How close should I trim a front rope seal? I usually use one piece seals.
