madkaw Posted March 3, 2012 Share Posted March 3, 2012 Anyone used a Speedi sleeve on their crank? I plan on having a Speedi sleeve on hand when I pull my motor to find my oil leak(which is more likely the rear main). I guess I was hoping someone had made this repair and would let me know what size sleeve you used and how it worked out for you. I would think the size would be the same for all L6 motors. As I type this I just remembered I have my original p-30 sitting in my barn which still has the crank sitting in there-soooo I guess I could measure myself, if I trust my mics -I still will put this thread out there for others and possible feedback.

Tony D Posted March 3, 2012 Share Posted March 3, 2012 I've used them for years. In fact I've misapplied them to repair vacuum pumps and liquid ring pumps as well! I don't recall now if the instructions call for it, but I've installed them with Loctite RC608 cylindrical parts locker with great effect.

madkaw Posted March 12, 2012 Author Share Posted March 12, 2012 Hey guys, I need a little help here. I want to order a Speedi sleeve for my engine and I don't have mics big enough to measure the end of my crank. I checked the FSM, but no luck there either. If someone can measure for me I would appreciate it!! Quote Link to comment Share on other sites More sharing options...
NewZed Posted March 12, 2012 Share Posted March 12, 2012 (edited) #24 here has some numbers - http://forums.hybridz.org/index.php/topic/57510-powerforce-harmonic-damper-install/page__st__20 I searched "damper pulley fit" just to see what was out there. Worth a look. Edit - Post #34 is even better, with an actual measurement. Of course, after reading the thread, you'll realize that yours will not be exactly the same.

madkaw Posted March 12, 2012 Author Share Posted March 12, 2012 Thanks for the reply, but I should have stated that this was for the rear main seal. I will look thru the thread but appears this is relevant to the front snout area. I need the OD of the crank where the flywheel mounts.

Tony D Posted March 13, 2012 Share Posted March 13, 2012 A 4 or 6" Digital Caliper from Harbor Freight is handy as hell for these instances. And cheap too! Failing an actual dimension, if you have the rear main seal, you can take it to most bearing houses and they will match the sleeve for the designed diameter. But having actual diameter helps. There is a speedy sleeve (metric) that fits it exactly. Don't forget your Loctite RC608 while you're in there! Good Luck in your quest!

madkaw Posted March 13, 2012 Author Share Posted March 13, 2012 I know it would be nice to have a 6" dial calipers. but I don't. I need to buy a cheapo set at harbor frieght as stated. I have gotten by without forever and my small collection of smaller OD mics have gotten me by. Harbor frieght is an hour away, so if someone could help me out it would be appreciated. I am trying to get this taken care while I am home for spring break with my son. Someone is loaning me their engine hoist and I don't want to have it for longer than need be.

madkaw Posted March 13, 2012 Author Share Posted March 13, 2012 Ummm, I know what a Speedi sleeve is and how it works and yes I have seen that video. What I need is a measurement !!!!!! Quote Link to comment Share on other sites More sharing options...
cockerstar Posted March 13, 2012 Share Posted March 13, 2012 (edited) Guess who happens to have a "trophy" consisting of a snapped crank, a pair of these cheap HF calipers Tony alludes to, and a camera all within reach of his laptop? This guy! Looks like 3.150 inches to me. No idea what the tolerance on these sub $10 calipers are though. Their precision seems to be just fine, but I don't know about the accuracy. The last digit shifted from a 0 to a 1 as I snapped the pic. The designed measurement is probably 80.0 mm. Sorry for the cell phone quality. The real camera was across the room and I was feeling lazy. edit: A quick google on their accuracy turns up a few guys that have measured them against standards and found the advertised accuracy (+/- 0.001") to be within spec.

madkaw Posted March 13, 2012 Author Share Posted March 13, 2012 Thanks so much for posting that. I bet those mice are close enough. Maybe someone else will chime in and verify your measurement Quote Link to comment Share on other sites More sharing options...
madkaw Posted March 13, 2012 Author Share Posted March 13, 2012 I might ask while you have your trophy out , to measure for the depth of the flange , also, if you can determine how deep the flywheel sits on the flange. I want to make sure the Speedi sleeve is the proper depth and does not interfere with the flywheel mounting. Thanks Quote Link to comment Share on other sites More sharing options...
NewZed Posted March 14, 2012 Share Posted March 14, 2012 Tsk, tsk. All of these facts in the first post and you could have had all of the answers in post #2. You might be able to derive it using the measurement given and the photo. Take the ratio. You'll have to estimate the camera viewing angle. You can even see where the seal rode.

beermanpete Posted March 14, 2012 Share Posted March 14, 2012 I also get 3.150" for the diameter. The distance from the flywheel mating surface to the end of the 3.150" section is 1.140". The distance to the inner seal wear line is 0.970". The distance to the outer seal wear line is 0.520". The seal is 0.5" wide. Quote Link to comment Share on other sites More sharing options...

beermanpete Posted March 14, 2012 Share Posted March 14, 2012 I looked at the oil seal and the markings on it are NAK TCL 80 100 13. This appears to means the the seal is made for an 80 mm shaft, which is 3.1496 inches. Quote Link to comment Share on other sites More sharing options...

I went to the Speedi Sleeve site and this is what I came up with according to your info According to this page http://www.skf.com/files/344136.pdf item 99315 seems to be the correct choice for our shaft-does anyone agree or disagree?

madkaw Posted March 14, 2012 Author Share Posted March 14, 2012 Sam, thanks, didn't know there was that option available. I thought Speedi sleeve was my only option. I will check out rock-auto's page. Quote Link to comment Share on other sites More sharing options...
