Ryan,



Thanks for the tips. I'll have to check out arnnworx.com.



Are you replacing the balance shaft/cam seals? If so, are you replacing the races as well? Paragon suggested I do that as a more certain way of curing current/preventing future leaks. And what exactly is a pin wrench?



I did just my balance shaft belt a couple of years ago, and it was pretty simple, except for the miserable contraption Porshce provides for adjusting the BS belt tension. I must have futzed with that stupid thing for over an hour before I got it to what seemed like a reasonable tightness.

Thanks for the info - your post was VERY helpful. My car isn't a daily driver, so I won't be under any time pressure to have the car running to get me to work on Monday. A few follow-up questions:



- Jason at Paragon feels strongly that I should replace the races while I do the balance shaft seals. I'm embarassed to ask, but what exactly are these? They sound like parts of some bearings, but if so, I don't see how they could contribute to leaks. Did you replace your races? If so, how hard was it to do?



- Other than the flywheel lock, and picks and such, did you you any other "special" tools on any part of the job?



- Finally (I hope), did you replace the oil pump sleeve along with the crank seal? And how hard is it to get the crank seal out? Again, I'm concerned that if it's really difficuly to pry out, I may damage something (e.g. gouging the shaft the the seal goes around) when I don't currently have a problem.



Thanks again![/quote]



Glad this helps. PM Sent -Scott

Cloud...yes I bought the races as well. The arnnworx DIY has a mention of the races and it does not look too hard to put in. (as in no press needed) We will see. I am waiting on my pin wrench so I can get at it again.



I am going to guess on my belt tension and have a shop set it.

Ryan,



Cuuck at Paragon also said the races aren't too difficult to r & r. I'm waiting for some parts myself, including the flywheel lock, which should all arrive sometime next week, so Iplan to tackle this job the weekend of the 22nd. When do you think you'll be doing the job on your car? It sounds like you're already underway, actually.



And again, what is a pin wrench? You're the second person who's mentioned it. The only tools I've ordered are the flywheel lock, and the flat 27 mm open end wrench.

OK, I looked up what a pin wrench is on google, and I finally understand. But which step of the belt/roller replacement is it needed for? And what type would you guys recommend getting? Thanks!

IMHO arnnworx.com has been just as useful as clarksgarage.com in making me able to fully self-maintain my car (I've never taken a Porsche to a mechanic for repairs!). His sight has way more than just tools for sale. Great write-ups, and fantastic tips and tricks all over. His notes on resealing a power steering rack saved me from doing it wrong.



Some of the best tools are intangible. I got all my special tools (belts and rear bearing) from Bruce - top notch service and quality. But I'm sure you could buy the same set from any source and it would work very well too.

Cloud, you will need the pin wrench to remove the gear/pully off the lower balance shaft. It keeps the pully from turning while allowing a socket onto the center nut.



I did not order or need the thin 27mm open end wrench. I have everything off except the lower b/s pully and the back guard.



I have to get those 2 frozen hex-heads off first to free the guard.

Ryan,



Thanks for the info on where the pin wrench is needed. Does the pin wrench need to be of a specific size for this job? I assume it's something I can pick up at my local Sears, right? I see Arnnworx has one, but it's $52. Ouch! Do I need one this expensive? I did a quick search on Google, and saw them for much less.



And thanks for the info on not needing the 27 mm thin wrench. I'll delete it from my order with Paragon. Did you use another tool in its place, like an adjustable wrench? And again, what step of the process is the 27 mm open end wrench theoretically needed for? From Arnnworx' site, it looks like more of a 944 thing, if I'm reading it right.



Thanks again. It's such a stress reliever to have such a great resource available

Cloud,



I did the same google and bought the tool from Harbor Freight. It won't work. The tool needs very long pins in order to work. I ordered the arnnworxs tool. In the Haynes manual they are using some adjustable pin wrench, so they must be out there, but I don't think Sears has one.



I am thinking the thin wrench might be for 944 use. I just used my open end wrenches and/or sockets on the rest of the stuff.

Ryan,



Thanks for the info on the pin wrench. You and Scott are the first ones from whom I had heard about this issue, but then again, probably not too many people change out their rollers when doing the belts. My car has over 100K miles on it now, and I track it a few times a year, so I think it's a good idea to replace them in my case. I think I'll do the rollers every other belt change from now on. I'll go ahead and arder arnnworx's pin wrench.

Ralph,



I kind of guessing here, so I wouldn't go forward until someone else confirms, but you may have stumbled into the "phantom roller." I don't remember the details, but I read something about it awhile back. Something about Porsche originally planning to have an extra roller as part of the assembly, but they ended up omitting it in the final design. However, it made it into the parts lists, and is included in some kits to this day. I know this sounds pretty hokey (kind of like my phantom coolant leak, which I may have found - stay tuned...), but I don't think I'm too far off.
