Hi guys

Thanks for your replies.

I believe it is called lead foot syndrome. :)

That would be the pot calling the kettle.  ;)

Ive been wondering how you were going with it, given the house stuff and all  ;)
Finally stopped moving and have the lap top out.
Ive not seen that one happen before, but glad you found something easy to fix/ replace.
The wear on the primary gear teeth looks quite normal to me, not optimal of course, but in not too bad a condition and I doubt it had anything to do with your clutch plate imploding like it did. The seal face also looks in pretty good nic.
When was the last time the clutch was apart? Was it just before Tamworth?

The house is on the market. Impending rego & the upcoming trip has meant that the engine has stepped up in priorities. I was, well if you can be, pleasantly surprised at the carnage at the bottom of the wok.  :o The clutch plate was replaced about 2 years ago, but the clutch had issues from time to time.The primary gear splines are worn & the bushes are a little scuffed. I can only imagine that the race up to the lookout at Tamworth probably had something to do with it letting go. :(


How badly worn are the primary gear bushes?  Is it possible that with movement in the bushes, the primary gear has been flexing the clutch plate to the point it stress cracked around the centre like that?

Personally i would just tell everyone that the extreme horse power of the engine ripped the centre out of the clutch plate, sounds so much better than fatigue to me.

Glad to hear it isn't something too serious.

Cheers

The bushes do have some wear & so do the splines. The 1100 has some get up & go, but I probably make up the additional horsepower by my driving style. :-[

Seems a bit of a strange thing to happen, but metal fatigue can do funny things. Once you get a crack here and there, one thing leads to another.... Sounds right that the pull up the steep hill to the lookout (done none too gently by the sound of it) could have been the last straw. A wonder you didn't have some sort of warning though if it was that bad.

Lucky you did the lookout run though, as it must have been right on the edge before that and it was much more comfortable (and more fun for us  ;)) sitting around the front of your cabin with a few beers commiserating and waiting for the tilt tray than it would have been sitting on the side of the highway the next day.

Glad to hear it seems like an easy fix anyway. Hopefully no more worrying noises surface once it's back on the road. Have you had a chance to get it back together and taken for a decent test run yet?

Hi

Just a quick update.

After spending most of Sunday & a few hrs today replacing the primary gear, clutch & the normal things that you see when everything is disassembled, we have forward & reverse! Yahoo! ;D 

I still have a few more hrs work to finish everything before doIng a shakedown run.

Alan.

Regarding clutch centre breaking (again during A trip to the Corner Store I believe...), I came across a reference on another forum saying that excessive primary gear to crankshaft clearance can cause this. I don't know if this is what is happening in this case but I am sure everyone would like to see the problem fixed once and for all.
Best wishes,
Mathew.
Cheers,
Mathew.

Hi,
Id been thinking something in this area also Mathew, but I think Incogneto and Mazy had replaced the primary gear before heading to the corner store?
Something else I was thinking about was end float, both in the primary gear thrust washer, and also the crank end float.

Certainly must be very frustrating, given all the hard work thats been put into prepping the Red One for travel.

Thanks guys

I have just parked it for the moment. While the clutch was apart for the second time Terry noticed the play in the primary gear. I measured it and it was 30 thou. Could that be enough to cause this? Anyhow, after the head gasket,  2 broken clutch plates, a painful electrical problem, radiator overheating & an alternator that was for most of the trip reading 12volts, we have come to the conclusion that it needs a full rebuild by someone that knows what they are doing, not me. I am sorry for the others that had to put up with our problems on the trip. Also, we owe a special thanks to Terry, as he stayed with us for another 2 days to try to get us home.

Mazy's battery is the same one as The Red One's. It is an AGM dry cell NS50P. Mazy has never had a charging problem, it reads 14.5volts.
I changed the alternator during the trip as it went from 13.5 volts to 12volts. After that it went from 13.5 volts for a while then went back to 12volts, slightly annoying. >:(  I swapped batteries with Terry on the last day, & voila ! It was back to 13.5v. I dont get it, is the battery capable of drawing the voltage down from the alternator if it is faulty? I have no idea. Also, up until the last day it started the moke & ran a fridge. Something to ponder.

Thanks

 Alan & Vicki

Hi,

I think there maybe two different angles inside the taper on the flywheel, just felt a small 'ridge' in there, but no marks on the end of the crank.

My suggestion is before you remove the engine from the car, prop up the engine and remove the 'wok' and put the starter motor back in and and turn the engine over or even start it if you are feeling confident enough, and just watch the flywheel spinning around and see if it is running true or if it is wandering around.

One thought is the flywheel might have moved on the crank or the crank end is slightly bent meaning the flywheel is not running true to the primary gear, either issue stressing the clutch plate laterally.

I can't talk for others on the trip but I think you deserve credit for your perseverance and retaining your sense of humour. Even the best prepared vehicle can give trouble. It's good that you were able to keep it going - mostly and get through. If I was going on a trip I would want to go with someone who might not have the best of everything but is at least prepared for anything, well as much as practical anyway.
I think Terry is on the money, something is stressing the clutch plate axially. A bent crank or flywheel, 30 thou is certainly a lot of primary gear clearance. The clearance between the primary gear bushes and the crank should also be considered - as mentioned previously.
Cheers,
Mathew.

Reading Matpauls post reminded me we looked at the movement of the crankshaft and there is a small amount of movement against the thrust bearings that you can feel, although i don't think it has any effect on the issue at hand other than to help justify a rebuild. :)
