Ok, so 3ish weeks after spinning a prop she's just gone and done a proper job.

Not sure whats gone but the bellhousing is in more than a standard OEM number of pieces and cock knows what else has happened.

Silly tart.

oh dear.

Shall I pick you up from Derby Station tomorrow so you can take this Mk1 that's sat on my drive back home?

Replace tomorrow with soon ish at some point and yes.

Not that I'm buying a mk1 to any of my family who may or may not be reading this. Soley to have a cup of tea with Rupert.

Do you use stock prop?

[Speedy88]

Oh dear. This makes me worry rather a lot

[magnumpi]

Bad times, hope it's an easy enough fix. I am at times known to drive with a heavy right foot but so far i've managed to not break anything, i think this is helped by a slightly slipping clutch rather than a prop or something snapping That said i've got a spare prop just in case, but my diff or gearbox is still making a lot of noise so replacements for them will be on the cards soon.


Looking back through the thread i saw this

Temp gauge runs at a quarter on the F7's, I have a feeling it's a gauge/sender mismatch as from memory we are using the renault sender but need to talk it through with Adam.

What was the case with that in the end? I ask as my temp gauge sits between only just passed the bottom mark, to quater with normal driving and takes ages to warm up and the heaters suck compared to how they were with the stock motor. Sitting stationary for a long time makes it go to around 3/4 then the fan kicks in, sound about normal or do i have issues?

Is it just cracked or does it have holes in it? Presumably it's a clutch failure of some sort that has been contained by the bell housing.

If you want a lift to go and get that mk1 let me know (yes, it really is cheaper for me to drive you up there than for you to get a train) as I'm going to have to come over to get that beer you owe me.

Thinking about it there must be something up with the drivetrain if you've managed to break a prop and shatter a bellhousing. we know that the 340 prop is capable of taking higher power than stock as Huskyracer had no problems with his at up to 180bhp and there are several F7R/P/whatevers running about with no issues (yet).

I do remember that the infamous Nessie (originally 5labs, then Foggys) had a bent output shaft from the bellhousing - maybe that's the weak point casuing the prop to twist and undue forces on the bellhousing. Either that or has a gearbox mount failed causing twisting issues?

EDIT: Perhaps if (and when) Foggys 343 is finished, we could bring the Mk1 down to you on our way (ish) to collecting it - it'd wouldn't be that out of the way to to go via Eastleigh to drop it off on the way to the Reigate area and would break up the journey nicely with an overnight stop at yours. this is of course assuming that Foggys 343 ever gets finished as it's been several Volvo Driver issues since Foggy first mentioned that the 343 should be back at his having been finished.........!

Forgive me for trying to be technical, but didnt I read someone say knackered engine/gearbox mounts was possibly causing all the prop problems? Mis - alignment or some such mallady?
Where yours pucka chris?

It's almost ok, but your fan should kick in at a half not at 3/4. The engine is over cooling rather than it being a sender mismatch, thing is with stock plumbing it always will. I'm trying to sort out a solution but it's bottom of the pile atm, during the cold though mine sits on the C mark most of the time, even though oil temp is up.

Cracked. Just about to go outside and pull it apart so will grab some pictars. I dont think it is clutch failure atm, I reckon it's misalignment (which means that Ben may have a technical thingy right.... )

.!

I reckon Filthy has had this problem before, but not spoken to him yet. I'm pretty certain I remember him needing a super quick bellhousing once. I agree though, I think a gearbox mount could have caused this looking at the fracture, added to some other symptoms I've had recently. The crack is clean all the way round the output shaft housing behind the engine mounts, just as though a sideload had been put on the prop....

I reckon so dude, no, mine are tired. I've been looking into a supplier to grab some new ones but struggling. Will know more hopefully later, but it's most likely to be this. The last couple of weeks (since the prop went) my gearstick moves under acceleration which is a sure sign of gearbox mount brokenness I just hope it hasn't scrapped the crank whilst it was spinning, I reckon I'm already looking at least at a clutch, bellhousing, another prop and new mounts all round

[volvosneverdie]

Blimey!
I dont want to alarm anyone, but me being right on a technical topic is one of the portents of the appocolypse.

[Frits]

haha

I'm suprised you still use stock prop Chris. My 1.4 turbo already killed the stock prop. A friend does have a 343 1.7 turbo, with anything more than standard pressure, it eat props. Well, turbo engines are pretty much torque happy, but I guess you also have pretty much torque.

The 343 1.7 turbo guy made a prop out of a volvo 200 series one. Wich works fine till now... Recoprop prop we used on both cars, but is was a hell and sended everything back in the end.

[magnumpi]

Ok Chris cheers for your reply re the cooling system. Tidyer pipework would certainly make the engine bay look a lot tidier and easier to work on.

I presume my GBox mounts are fine, but my engine mount was commented on by Adam at the time of engine swap saying, it's knackered and needs replacing. The one that needs a notch chopping out of it for the clutch, well it's still on and hasn't caused any issues yet.

So we know the prop is th achilies heel, so if as some have done fit a modded/uprated prop, whats the next weak part in line that will break instead?

[V6 Man]

To be fair though Chris' car does see more than a 'normal' cars' share of abuse. Assuming mounts, prop and output shaft are all good then there may be no need for concern about their strength for most owners of uprated cars.

Fake is a different kettle of fish as she doesn't see 'normal' use. Chris has had underbody issues in the past (diff flanges, fuel tanks etc) and it could simply be that the twisting, bumping and bashing that Fake gets in the course of a rally have finally taken their toll.

I know this doesn't help Chris with regard to his car, but it maybe that it isn't quite the cause for concern that we think it is for other cars.

One of these days i'm going to learn to just keep my mouth shut
