HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Trans mount dims

Post  xschop on Thu Aug 20, 2009 1:39 pm

Anybody have a spare tranny mount laying aroung to measure up?
I have an 85.5 car and want a stronger mount with Polyurethane isolators to dampen the road noise, so I don't think I want a solid one.

Do a search on RL.

Some guys over in the Turbo 944 section made a semi-solid mount from a stock mount by pouring in some urethane rubber stuff from Mcmaster-carr.

They say it works very well, and is WAY cheaper than the LR mounts.

dims

Post  xschop on Thu Aug 20, 2009 3:53 pm

I did that very trick to a set of Honda Civic mounts, I used 60A poly and I am still driving on them after 3 years. I want to redesign the tranny mount so that a single bolt releases the tranny from the mount from the side. I remember the two bolts that go from the tranny bracket to the tranny mount being a Byotch! to get to while laying on the ground.

You have the best ideas....

I don't have one to measure up, so I'm no longer of any use lol.

Here's the thread incase anyone else wants it. The McMaster-carr part number is further on in the thread.

Rob, I modified mine using 3M window adhesive. Leave the mount assembled, put masking tape around it and pour the adhesive in.

I actually just did this to my trans mount. I got some 80 rh urethane off ebay for about $30. Wrapped the whole thing in scotch tape, poked some holes and put the bolts back in (could be pretty bad if i didn't!), then poured away. Assuming the stuff holds up, it looks to be exactly what i want!

I still have enough to do a second trans mount, but i've promised it to my dad for his car. In all, a very cheap solution...

80 rh? is that the equivalent hardness to a car tire? 60A is about what the Polyurethane is on all the energy suspension stuff. The Graphite impregnated PU that I'm using for the RX7 arms is the hardness I'm after on all the suspension related stuff. And that tranny bracket that is in the other thread with some type of Polyurethane mount may be ideal solution and not have so much road noise as compared to a solid tranny mount alone.

A car tire seems about right. To be honest i just went off what others had recommended (on rennlist). For my purposes it seems to just about perfect--i pretty much wanted a solid mount, but not the road noise. I'll report back on it once my car is running again!

Prior to going this route, i had considered just making a 1/4" steel plate, welding a 1/4 plate vertically, bracing, and then clamping some generic polyurethane endlink bushings between the mount and the crossmember (subtracting the thickness of the bushings from the overall height). Would have been a cheap way to do it, but i'm real happy with how this filled mount turned out for ~15 minutes worth of work and ~$15! afro

Trans Brace

Post  xschop on Mon Oct 26, 2009 12:34 pm

Did Anyone ever build the tranny brace?
I will have 3ft of spare 22mm Billet rod and female heims left over from the strut tower brace I'm making and can make a first prototype.

Maybe try a heim joint with a polyurethane bushing.

Post  Arthropraxis on Mon Oct 26, 2009 12:56 pm

Someone in the thread linked above made a brace with heim joints and threaded shaft. He took it off because it rattled so much no matter how much he preloaded it. But the picture he had of the heim joint was just metal. I wonder how much better that would be with a eurathane bushing heim joint?

I think this is what you are talking about.

Post  Arthropraxis on Mon Oct 26, 2009 2:39 pm

If I linked it right. The guy that make it says it rattled to much and took it off. If you were to use a heim joint with a polyurethane bushing that may be better.

Since this topic came up again, i figured i'd mention that i have enough urethane to fill one more transmission mount. If anybody wants it, send me a PM...

Since it's 1/2 of what i bought, i'll sell it for 1/2 of what i paid for it Smile

From that thread:
i pulled the brace that rattled no matter how much pre-load, and installed a solid mount that i found on a parts turbo car that we parted out. Havent had a problem since. - Still have the brace in the attic.

Seemed like a good idea, but just wasn't necessary i guess...

From what I've read, I'll have to back up 948. I read about people using the 3M window adhesive to build the entire center for engine mounts; seems like the a good method.

The 3M Fast Window Weld works great. I've heard that the other stuff doesn't dry very well when it is too thick. I've used it many times and it works great. Cheap too.

If by "other stuff" you mean the polyurethane...it dried completely in 24 hours.

I meant the non "fast" 3M Window Weld. Some people have told me that it takes forever for the mount to completely cure inside. I have only used the fast type.

Good to know! I probably would have gone that route if i were still looking...that stuff is a little easier to get ahold of than a DIY polyurethane kit!

Post  xschop on Thu Feb 18, 2010 3:08 pm

I finally got all the dims needed to build solid Billet mounts and I'm Gonna tweek them to run 1" Red Poly mounts (60A) on all 4 corners.

Rubber is outdated.... [You must be registered and logged in to see this link.]

It kinda depends. I think i would go either rubber or solid. No point in doing all the redesign work for polyurethane...you'll just end up with something that's so stiff it might as well be solid. And if it might as well be solid, then you might as well save $120, right?

Every once in a while some different designs pop up on ebay. The billet design is nice, but you really only need a couple of plates welded together. If i wasn't so happy with my filled mount, i'd probably spend an hour and make one....

60A PU is where it's at. It is what most all aftermarket bushings are made from. I mic'd out a good used tranny mount and I do not like how easy it is to flex/oscillate from side to side, this is what kills the driver's CV joint. PU on the four corners will take care of this and still reduce the vibration noise. Got the billet block and Polyurethane Bushings on the way. If someone wants a good used factory tranny mount to do the 3M fill job, hit me up. From what I see, the factory alloy hanger needs to be acid washed or boiled so the old rubber will bond to the PU when doing the fill mod and the back side rubber needs to be ground down and PU added there because new material needs to be added to isolate the backside of the metal hanger and the tranny X-member or you will still get alot of resonance....my $0.02

I always thought endlink bushings would be a good fit (and cheap) for the mount. $10 at Autozone for a set of 8 polyurethane.... I'm sure they have some rubber ones for cheap, too.

PS--could somebody turn off these damn 240 second waits before replying/editing!? ! What a PITA!!!

Amen to that, brother. I'm waiting for the first 5 sets to show up for the only unknown Dim. where the nipples fit into the baseplate. So basically with a solid mount subtracting 1/2" out the equation, like you say, you can have a solid or Poly backed mount with inexpensive replaceable bushings.....
