PDM Snout Sleeve Kit Installed

goobie · 07-21-2003, 05:57 PM

In a final attempt to beat clutch shudder I had a PDM snout sleeve kit installed today during a visit at Lachute Subaru (Thanks guys!). I purchased the kit from RK Performance. The kit is of really good quality and is a complete kit. When I say complete, it includes absolutly everything needed to install it!
Kit contents:
- PDM Snout Sleeve
- Throw out Bearing (oversized)
- Set Screws and Allen Wrench
- Lithium Grease
- Decal (Stating part numbers for replacement throwout bearing)
- Detailed Instructions

When the transmission came out, there didn't appear to be much wear on the snout (I've seen them worse!), but installed it regardless.

Well, So far so good! No shudder yet and the clutch operation is definatly the smoothest it has ever been! I really need to drive it some more before I can with confidance if it cured the shudder or not. But I'll keep you posted for those interested.

Here are some pictures of the kit.

Cheers,
Chad

Cool! Do they have a website?

Sure wish I had known about this a month ago!! Just had the engine out for H-G job and my new Independent Subie Specialist found the Trans snout grooved. He replaced the T-O and pilot, after sanding things a bit, but I'd have dropped the $$ for this piece in a second!! Thanks for the pics! Just might get one to be ready when it comes time for a new clutch. Looks like just the thing to go with an up-graded clutch too!! Dayammm!!

Yeah I know what you mean Glenn... It sucks finding out about things like this after the fact but at least you know now....

I figured there would be people interested in this little known product. When I found out about it, I couldn't find any pictures or much detailed information about it, other than it seemed like a half-decent idea. So I ordered one up for myself and took some pictures to post for others to see. I think this would be an excellent addition for anyone doing a clutch job even if they don't have wear on thier snout. Without a hard surface like this sleeve, it WILL eventually wear. This will prevent it from happening....

As for my clutch sudder issues.... it's day 4 now after the install. The clutch is still smoother than it has ever been and engages consistantly (no wandering engagement point) but on humid days, I'll still get a little shudder, but that is a function of the clutch disc material and not snout wear... with the snout sleeve in place i can easily modulate the clutch to avoid sudder on humid days, unlike before when it was difficult to get around. I think the OEM T/O bearing riding on an aluminum (or whatever the soft alloy is) snout made for a real sticky friction surface... When the OEM T/O bearing came out, I noticed it (and the snout) were caked with a dark paste-like substance that no doubt was a result of the bearing sliding and wearing on soft metal and mixing with the grease and clutch dust. This made the surface very sticky. I don't think this will be a problem again!

How is it now, a few weeks later? Still all good?

goobie · 08-21-2003, 01:22 PM

It's been installed now for almost a month and I have put about 5500KM's on it since installation (No I don't normally drive that much in one month, but this time I did!) The clutch action still feels amazing. It's very smooth, engagment point is consistant but I STILL get shudder when it's humid outside (which is every day it seems lately). I spoke to a tech about this and was told it's caused by the type of material in the clutch disk. The thing that bites me in the ass is that I'm running an Exedy performance clutch! I've never heard of anyone that still has shutter with an Exedy. Is there anyone else with an exedy clutch still getting shutter?

Even though I still have a little shutter I still feel the sleeve kit is a worth while piece. It has made my clutch operation smoother (the T/O bearing rides on a much smoother surface now)...It will prevent any future wear on your transmission snout and the T/O bearing supplied with the kit looks like a higher quality bearing than the O.E. unit.

Cheers,
Chad

I have an Exedy clutch and I still have shudder.

Maybe it has to do with using organic clutches?

8Complex · 08-21-2003, 03:15 PM

Shudder has to due to the disc having inconsistent grip (or maybe the pressure plate being inconsistent at times), not the snout kit. The snout kit will solve if you have severe binding in the throwout bearing actuation. You might be able to feel something like that, but I haven't seen an instance where it was needed yet.

Shinji N · 08-21-2003, 06:02 PM

Thanks for posting this. You are a saint.

Exedy makes the OEM clutch disc, so the compound might be the same.
I wonder if Sachs makes a disc for Subies, I've never heard of a Sachs clutch doing this.

ImprezaRS dot com · 08-21-2003, 08:12 PM

I had an Exedy clutch, and it didn't shudder. But, when I went to a CF/Metalic disk it did. The PDM snout kit fixed the shudder with the CF Metalic disk.

The shudder came back with a 6 puck ceramic clutch, but that is to be expected with one of those.

This snout kit is wonderful, highly recommended.

What do you mean by "inconsistant" ? Other than glazing, how/why would the grip (fricition coefficient) change in the clutch?

Chad

8Complex · 08-22-2003, 01:41 PM

It's been speculated that the humidity and the cold can make the disc seem like it's glazed (slip/grip). Notice how shudder is worst when your clutch is cold and/or in the mornings when it's raining?

mofoporn · 09-13-2003, 01:35 AM

I also have this on my car and their is no complants. The clutch engagement is much smoother now. I also recomend this. A++

I am considering checking this kit out, but I already had my clutch replaced a little while back. What is required to install this kit, and how hard would it be to do, etc.?

Jonathan

snowone · 01-02-2004, 08:44 PM

Pretty much a full clutch remove & Replace. Haven't done it myself, but am waiting for my clutch to dye, and then do it all at once. That chirp/squeek comes, goes, and drives me insane.

Seriously??? This is no good. Is this to say that the clutch needs to be removed to install the sleeve, or that the same genearl amount of work is involved. I forget exactly what is involved with doing a clutch change (drop tranny.... etc?, a shop did mine)

Charlie-III · 01-02-2004, 11:45 PM

The trans has to come out to get to the snout. Thus almost as much work as doing a clutch.

Legacy777 · 01-03-2004, 02:09 AM

PDM pretty much went tits up like jc sports (like father like son). Not sure if they still have snout kits floating around.

ilmaestro · 01-03-2004, 03:59 AM

I saw a vendor's site earlier today that supposedly had the kits still. It was my first time visiting the site though, lost the URL, heh.

HamFist · 01-03-2004, 05:51 AM

They're still available www.flat4engineering.com

ilmaestro · 02-24-2004, 09:54 PM

A little bump. I am pulling my engine soon to do a headgasket replacement and am probably going to give the PDM snout kit a try since I am sick of shudder even after I replaced my clutch with an exedy sport. It does it on dry or humid days, mostly when engaging from a stop.

Jonathan

goobie · 02-25-2004, 11:14 AM

Mine Shudder is all but gone! 99.9% shudder free

on a really hot humid day (Yes we do get those in Canada

)
I will still get a slight shudder on engagement but is very controllable and is more a gentle flutter compared to the violent shudder I used to experience.

Sad to hear PDM went Tango Uniform. They seemed like a great company.

I replied to your PM ilmaestro, Good luck with the clutch work!

I just wanted to bump this thread since I recently installed my PDM snout sleeve kit. The kit is amazing... well, actually, it's pretty simple but the results are amazing. I replaced my clutch and flywheel about a year ago and have had severe shudder ever since. The shudder is absolutely gone now that I installed the PDM snout kit, and I havn't experienced it at all after a week of driving and cold starts, etc.

When I pulled the motor and took a look at the transmission snout, I could clearly see a groove that had been worn in the snout where the original throwout bearing rode on it. The steel sleeve covers this up and no more shudder.

Good product... happy as hell I bought it.
