94 850 front cam seal tool

Post by kahl »

Hi guys,
Following up on some other posts about front cam seal and tools I made a tool that works great. If anyone wishes to borrow it PM me. The tool will bottom out against the camshaft end when the seal is fully seated.

Are you seating it flush with the outer surface of the head or all the way in? Either seems to work well, just curious.

Terrific tool design!

That's how the Volvo tool works. It seats the face of the seal just inside the well, even with the edge of the bevel.

Great info, thanks. I seat them flush, a while back I made a variant of kahl's tool, also uses wood and PVC but is not nearly so pretty, and it is a slightly oversize diameter that won't let the seal go in beyond flush. But makes it perfectly straight, I like that part.

As mentioned in the DIY link (TB, SB, cam seals DIY) posted above, I used 1-1/2 inch PVC Plumbing Coupler.

If I were to do it again, this is what I'd do:
- Get the 1-1/2 inch PVC Coupler ($0.90 at Home Depot etc.)
- Cut it down to H = 1cm or so. This way I can use the factory cam sprocket bolts.
Otherwise, leave the PVC Coupler alone (don't cut it) but use longer bolts.
- Once the PVC Coupler is cut down, all you have to do is to file the outer edges a bit to bevel it.
Test it on the new seal, the outer edge of the PVC Coupler should be a tiny bit smaller than the very edge of the new seal.
- Then use the cam sprocket + "new tool" and slowly tighten the bolts down to seat the new cam seal.

- Apply apply grease/oil to the new seal during installation.

See photo, I took this photo from my other DIY and modify it to update the concept, see the caption in the RED box on the right side of the photo...
