    Comment on Motion-Pro Valve tool...

    Today, I re-shimmed the one exhaust valve noted in my 'sealing' thread, so I figured this would be a good time to actually use my M-P tool.

    After dinking with it and getting it to fit, I'm still not impressed.. Problem? Yes, it gave me enough room to get at the shim, but the shim would not come out!! Magnets, picked at the edge, tried everything I could think of for twenty minutes with no success. Finally went ahead and pulled the cam again, and I had to use a knife point into the 'adjustor notch' and pry the shim out. Very tight fit....

    YMMV, but it's back into the 'unused tool' drawer for mine...

    Yeah, they can be difficult sometimes but you can turn the shim bucket to where the notch is and I used a pocket screwdriver to break the oil film vacuum and they lifted right out.

      I messed around with mine for about 10 minutes then took it to the bench grinder.... works like a charm now!

        Yep, before installing the tool, rotate the shim bucket so the notch is accessible.

          Greg, even after I pulled the cam, it still took considerable effort to pry the shim out. Mine seem to be a very tight fit into the bucket...

            I used dental picks to break the oil vacuum and then lift the shim out.

              Naw, it's just a vacuum from the oil film. I just used the corner of a pocket screwdriver like I said. A dental pick like Nate says would probably be better though. Just gotta get a little air under them and they'll come right out. I also kept a small magnet on them so when they did break suction I wouldn't drop them again. Learned that from experience.

                You can also use a shot of compressed air to aid along with the pick tool.

                  cam lobe pointed away from bucket...i rolled the bucket around to expose the slot in it with my finger, rolled motor to depress bucket all the way, slid the now well clearanced tool into place, bolted it down. rolled motor away from tool untill lobe was facing opposite of bucket, popped the shim loose with my box knife, and picked it out with a flex magnet rated to 4lbs. worked great ymmv

                    You'd think MO-PRO could design and build those valve tools so they wouldn't have to be screwed with in order to work. When I buy a tool for a specific job, I expect it to work without having to correct an engineering problem. When I got mine, I must have worked with it for the better part of a day, then I ground it down and tried again. Still couldn't get it to work. I finally removed both cams, and re-shimmed all valves (with new shims) and had it back together. I'm still convinced it would have taken me longer just to get the tool to work with a single valve bucket. If the tool was designed correctly, it wouldn't be so hard for so many to make it work.

                      I must just be lucky because mine worked good right out of the box. The hardest part was getting the "feel" for the edge of the bucket.

                        I threw mine in the trash YEARS ago.

                        It was designed as a piece of ****, it was built as a piece of **** how could it be anything BUT a piece of ****?

                            a question

                            As long as we're talking about this, where do you guys get your shims? And what's the most cost effective way to go about it? Are assortment sets available? Or should open it up, measure what I need, and then go try to find them?
                            Hill? What hill? I didn't see any hill! Why wasn't there a sign? And where are my keys?
