Yes, it does but good reminder.

I did have a funny occurrence while waiting for the bubbles to subside. I thought, hey I should probably pump the pedal, because you normally do that when bleeding a hydraulic system.

I stuck a leg in the car and touched the pedal and it went "thump!" and hit the floor. I couldn't pull it up with a few pounds of force, so I shut the bleed screw, depressurized the pump bottle and then I was able to pull the pedal up and start the process again.

A bit of a "note to self" moment.

Clearly, using said product, while matching the colour of your car, will mean you are not following others and thereby, 'on your own'.;) Let us know how it works out for you...

Oh, you mean you didn't have an assistant pump the pedal and hold it down before you opened the bleed screw?

Steved,
I considered the possible induction of air at the bleed screw, so I was opening it just enough also. I kept it up until I got zero bubbles.

My clutch functions well, or well enough. Now I'm casting a glance at the shift linkage. Lots of adjustments needed.

My shifter is kind of floppy and imprecise too and sometimes when I go 2nd to 3rd it kind of bogs down. I have order a 997 shifter and when I put that in, hopefully it will improve due to the new bushings and new fasteners in the shifter.

Veering off track
 
I know we started bleeding hydraulics and now were into mechanical linkage so I must pose a question. Is the 997 shifter an improvement ? ? is it a drop in ??, I see no real reason for the short shifter ?? ...if so enlighten me please.

Thanks

Dwight

It is a drop in, and it is supposedly an improvement for a couple of reasons.

It is a 15% shorter throw than the stock 986 shifter.
It will have new bushings, which can help keep the shifter from being sloppy in side to side motion.
It comes with new cable ends and that clip on, and the inside pieces can wear down can cause sloppy shifting, or sometimes even breaks completely.

Note that I said supposedly :) I am getting mine because another guy in town got one on his 1999 996 and he loves it, and it got me sold :) If some of the sloppiness goes away it will be a bonus :)

Sounds like it is in my future
 
Is there a turn key kit ? or a parts list to buy ?

rdass623 08-04-2014 06:22 PM

short shifters are not a necessity, just a personal preference. if you decide to get one, the $40 - $50 ones on e-bay are great, and a quarter of the price of anything else. an exact copy of the b&m, and swaps the cogs great. shift effort is increased but the throw is reduced by about half.

This is the one I got/am getting (it has shipped but not yet arrived)

99742401000 - Gearshift Bracket For Manual Transmissions - ES#1499714

There are other kits that include just the inner part and you reuse the outer part from ebay and other places. Do a search on short shifters here and you will learn more than you probably wanted to know about shifters. ��

Thats looks to be just the bracket and not the actual shifter ?

That is the shifter assembly.

That's funny, I got exactly the opposite result.

My kid got a lift put into one of the bays of his garage a couple weeks ago and invited me to use it whenever he wasn't. So, pretty much right off the bat I took him up on it (since my brakes/clutch haven't been flushed in forever).

I used the Motive pressure bleeder (works wonderfully), and as I opened the first valve I got lots of air. "Ok, not that abnormal I guess, it'll stop soon" I thought. A minute later the string of air bubbles continued. My kid tells me to open it wider, that the brake lines in his car pass air bubbles unless he ups the flow. So, I took it from 1/4 turn open to 1/2 turn. Don't exactly understand it, but the bubbles disappeared pretty much immediately.

What size clear tubing do I need for bleeding the brakes on my 02 base? I found 13/16” mentioned in a thread and I wanted to confirm if this is the correct size.. Thanks!

Assuming you're talking about inside diameter, that should be right. I'll put it this way: that size is what worked well in my '01, so I'm reasonably sure it'll work in yours.

Eric-986 07-07-2020 05:34 AM

13/16 seems pretty big....... maybe 3/16?

Yeah, 13/16 is like 3/4 of an in! 3/16 or 1/4 makes more sense.

robdelorenzo 07-07-2020 07:36 AM

Great. As always, thank you forum members. I have everything ready to p/up @ Pelican but it looks like a trip to Home Despot is in order for the tubing.

Frodo 07-07-2020 10:22 AM

Ha! That's funny. Having just done this, I knew the answer was 3/16". My eye just skipped right over the '1'

Yeah, 13/16" tubing could get pretty messy.. ;)
