cat TEN motor Question- Crankshaft Pulley

Catmatt, there should be a felt seal on the crankshaft pulley, it fits behind
the round plate that is fitted to the front timing cover with 4 cap screws,
it is shown in the parts book, on the pages showing the engine block,
seal part # T267, retainer plate part # T268,

the 1/8" gap from the end of the crank to the front of the pulley should not
be a problem as the pulley should always overhang the crank a bit in order
for the retaining bolt/dog to hold it tight, if you are getting oil seepage
along the crank, I would make a cork gasket to go between the end of the
crank and the securing bolt/dog, (so it fits inside the pulley),select a cork that is slightly thicker than the 1/8" gap and this will compress and fill the gap just right,

it always pays to test run engines before painting, I like to test run the hole
skid unit up on stands before I get too carried away with the spray gun!

good luck,

shovel man.

Shovel Man,

Yes I always test everything before getting carried away with a nice paint job. I do see the seal- I was looking at the crankshaft page and it does not refrence it there. Now I have to figure out if I put the seal in there😕

Thanks for your help

I was able to use a puller and partially pull the pulley off the shaft without having to remove the timing cover or the govenor shaft. With the pully pulled forward i was able to remove the nuts to the plate behind the pulley and confirm I had installed the felt seal. Closer inspection reavealed a slight leak from the oil pan. The bolts were a little loose so I tightened them. Hopefully that will solve the problem! Thanks for your quick reply!

Pull the pulley clean off the oil with some brake cleaner and put some Permatex #2 Form-a-gasket around the crank especially on the key and push the pulley back on. This is probably where the oil is coming from.

Steve,

Are you saying the oil is coming "thru" the pulley along the shafy and key way? That does make sense. I probably can just seal it from the outside, behind the jaw?

That's what I said in the above thread, put a cork gasket behind the jaw
bolt that secures the pulley.

Thanks shovel man- I had missed that the first time i read it!

Matt,
Everyone seems to have this covered and like always everyone has given great advice. Sounds like you will have this one sealed up in no time. The one last thing that I do is put a little silicon between the round plate and the front cover. The felt seal will soak up a certain amount of oil. Their is a drain back hole at the bottom going back into the engine. The small amount of silicon that I make reference to will help seal the bottom of the plate to prevent leakage there. Good luck. Post pictures when you are finished!
