Snap! Pow! Vroom!!! Clunk,clunk,clunk... gosh, now what!?!?!?

[82SC]

rev is when the motor is running into the high RPM...usually in neutral

"I revved my motor to 7000RPM at the stoplight to get the attention of the girl with the big breasts"

that would be a typical use of the sentence



yes I've had mine come loose too...beat the crap out of my heat exchanger...drilling the bolts is something I am definately thinking about...I checked all of my CV bolt twice last time I installed

Maybe some one should make a jig and sell them...maybe Wayne...like you don't have enough to do...hmmm...drilled CV bolts + safety wire + wire twister pliers make a pretty nice package....dammit...maybe I'll do it...

I also read that when you thread the wire and loop it over one side of the bolt it should go one the right side of the bolt (opposite of the loosening direction) not that it matters too much, since any direction is gonna reduce the chances...and also a quick dab with a paint pen (art store) can show if any have loosened at all

'morgen, Rod911. "Rev" comes from "revolution" (no, not that kind, but the other kind, the rpm kind!). But my question is, what the the "CV" stand for (I know it is not "Curriculum Vitae"!)

[82SC]

hahaha since I am the only one awake on the west coast and the pelicanites in europe are the only ones up...I'll answer this too

CV - constant velocity joint

it is 2 races with ball bearing in between. All the gaps are filled with thick grease...

there are 2 per side. On either side the axle shaft connects the transmission to the wheel hub...and there is a CV joint at each end of the shaft...the shaft attaches to the inner race and the tranny flange or the wheel hub attaches to the the outer flange...with the balls and the grease inbetween the 2 races

pictures of the 2 races...no ball bearing though: More CV Joint Mayhem! Assistance Needed.

the CV joint allows for a large range of motion between the shaft and the tranny or wheel hub so that the shaft can spin at all the different angles the wheel will be in relation to the tranny (all the suspension movement)

hope that answers your question

Sure does, 82SC (you musta gone off to bed by now, I would ...hope for you... !)

The backfiring and poor running engine were probably caused by your carbs sitting there for some time with the throttle wide open. Your engine was likely partially flooded.

Already available. A good industrial or aircraft supply will have the drill jig, special lock-wiring pliers, and the safety wire. This is nothing new to A & P mechanics, m/c and car racers, etc.

I do not understand how the axle shaft can suddenly separate from the transmission without warning. As the six bolts gradually work loose, surely there would be a great deal of noise back there, and you would know something was going wrong?

[Groesbeck Hurricane]

There is not always alot of warning. I had much warning with my old Citroen, but when the 911 did this to me it was very, very sudden. Fortunately I was just pulling out of a stop sign. I pushed the car and after proving to the cops (overzealous type, not the normal ones) that I was the owner and did not have anything illegal on me they allowed me to have a tow truck take me home.

Doug:
If you need (or want) any assistance, lemmeno. Fussin' with a broke car is a lot more fun than going to play at an AX.

Elderly valve springs may not support 7400 revs. A compression check will tell the tale. I have a tester if you have the need along with other implements of destruction .....stud pullers, left hand drills, BFHs.....yada.

I think me and Keith cab had twin cars. Almost the exact same experience with an 77 930. Except I caused it by not using the proper torque. Crawled under the car and reattached the axle with the three remaining bolts and limped home.

I have also had them come loose on my early car, but caught them early enough.

I check them more often now, but have not had any come loose in many years.

Can't help noticing that all these stories of axles detaching are about pre-1985 cars. According to Bentley, the 1985 year switched from M8 to M10 bolts and torque went from 30 ft lbs to 60 ft lbs. Anyone have an axle come loose on an '85 or later 911?

[Snitzler]

I just rebuilt my throttle linkage at the transmission. The usual clean, paint and lube. When I removed that shaft that goes into the transmission, trans oil came out. It is an open hole. I don't know if your trans is the same but when your all done, check your trans oil level.

Props for bringing a jack and stands to the street !

I have been pretty confident with Nord Locks on my CV Joint bolts. There are a couple threads here - you may need 5mm longer bolts.

Before the Nord locks I had them safety wired.

Reconstructing Constant Velocity (CV) Joints

[RDM]

THE thread. Thanks to Grady.

[Trackrash]

Ya know, I have to ask. If this has happened to you was there any warning before, kapow?

I had the CV come loose on my Vanagan many years ago. HOWEVER, I noticed a clunking. When I got to the Disneyland parking lot, I looked under my van and detected a loose CV. I got out my allen wrenches and got the bolts as tight as possible. Drove the hundred miles home and retorqued them. I am sure that if I had not heard the clunking and took action, the CV would have eventually come loose.

Any similar experiences?

[HarryD]

Similar incident on my 911 last year.
