Hi,

Does anyone know if this tool:
Volvo Special Tools 999-5283 Crankshaft Front Seal Drift
Is the one for installing the front crank seal?

Thanks,

Ron

Yes it is, and I have one. But I'm embarrassed to say I can't figure out how to use it. It doesn't work like the B21/23 5024, which uses the threaded bolt hole to push the seal into place.

Instead, the 5283 has a projecting, rather sharp-edged front "snout", whose inside diameter just fits over the crank bearing surface. With a new seal in place on this "snout", I guess you just tap the seal into the bore, then pull the tool out. The tool's bore tolerance keeps it aligned during seal installation.

The problem for me has been in getting a new seal mounted on the tool without damaging the seal lip on the snout's sharp leading edge.

The tool comes with an aluminum cap to protect that edge, but that's all it does as far as I can tell. It doesn't seem to have anything to do with using the tool.

Excuse me if I'm a little "rusty" in tech-english.. but,

According to the manual, you grease the seal and mount it "on" the tool, then tap it in.
The manual doesn't actually say more..

If you damage the seal, maybe you're using un-original seal?
I just don't understand if the procedure should have "warning" on that problem, now that it doesn't??

The manual says, "..if the axel is a little worn, the seal kan be pressed further 3 mm." - I haven't been there, but maybe it will mean something for you?

Thank you for the reply. I will respond to each part.

"According to the manual, you grease the seal and mount it "on" the tool, then tap it in. The manual doesn't actually say more.."

Correct -- but "mounting" the seal on the sharp edged tool is the problem. The edge is sharp enough to require a protective storage cap, and the outside diameter, where you mount the seal, is about 1.6mm bigger than the end of the crankshaft. So the seal is that much more difficult to place on the tool.

"If you damage the seal, maybe you're using un-original seal?
I just don't understand if the procedure should have "warning" on that problem, now that it doesn't??"

I use Volvo and Elring seals, but as an "amateur" mechanic, I don't replace them as often as a professional like yourself. A "warning" probably would not be needed for someone who has been shown how to use the tool. I believe it may just be a matter of practice. (And maybe more grease?)

"The manual says, "..if the axel is a little worn, the seal kan be pressed further 3 mm." - I haven't been there, but maybe it will mean something for you?"

Yes, the tool will only press the seal in even (or "flush") with the face of the seal carrier. So the manual is saying that putting the seal in as much as 3mm deeper is allowable, to avoid grooves from previous seal wear. That is "standard practice" with any seal, I believe.

BUT, that would require a different tool, and would expose the risk of positioning the seal crookedly, which is a different issue and not related to using the tool for seal installation.

I will be much more careful (and use more grease) the next time.

Bruce,

Thanks a lot for your "easier for a dane"-explaination!

I just get a little affraid if I "stepped on your toes"? -if so, that was really not intended!

As I write, I haven't "been there" and I'm not professional, I just contributed by having the Volvo servicebook for the B204/B234's engines, and tried to help out as much as I could.

Sometimes language can course misunderstandings, and I'm really not even sure if it is wrong of me to be affraid..

Anyway, I hope that Ron can use your help!

:-)

According to my Volvo servicebook, it is! (if I translate right!)

For the B204/B234 engine:
