Sorry Riaan

Had your conversion confused with Citfield's one:

It is not a whining noise, it is more of a scratching noise, but only now and then.

I can't test if it is the front diff, because the back prop shaft is out of balance, first have to balance that prop, but the noise does sound worst since i have removed the back prop shaft or maybe i am just going crazy  .

Age is catching up on me

Spikes we determined that Allen's propshaft is the problem, he should have it resolved today

[Riaan]

Ok, chatted to Allen, its not the propshaft, it is inside front diff, and he aint had a chance to take it out yet.

I think this saga is continuing in DIYGUY's thread.

If I remember correctlly, Riaan experienced a problem  when he drove up his driveway some time ago. As far as I know he never reported the cause of the problem, but maybe the current issue can be linked to the previous problem ?

Here is that post

But that was no forward movement

I could be completely wrong, but I started thinking that DIYGUY should at least have a proper look at that Bellhousing modification, as well as possible damage to the Clutch, clutch Pressure plate, as well as possible damage to:

1. The big bearing just inside the gearbox housing (nest to the Bellhousing).
2. Needle Bearing (between the Input and Output shafts, inside the gearbox)
3. Condition of the gears at the Input Shaft ( Inside the gearbox housing).
as mentioned:
4. Clutch plate, and clutch Pressure plate.
5. Pilot bearing at the Flywheel.

The reason for my suspision:
1. I know for a fact that Bellhousing modifications like this are extremely complicated, and often lead to clutch and gearbox problems.
2. At one of his posts (I think page 1 or 2) Riaan mentioned that the Bellhousing had to "go back to the engineers for skimming". To my mind this means that the "engineers" had to do some kind of modification, to try and make this Bellhousing work properly. I think there is a strong possibility that this beehousing mod could still be part of the current problem.
3. Riaan already reported some strange kind of problem - when he drove up his driveway.

4. I know for a fact that the initial Bellhousing which has been modified for  the local Lada with supercharged Toyota engine and Alfa gearbox simply had to be dumped - because of a misalignment problem. The modification to this Bellhousing has been done by specialists, and has been done in the same way as Riaan's bellousing. Despite the fact that this mod was done by specialists / professionals, the bellhousing has been dumped - because it caused serious clutch problems. To make this modification work properly, a loose adaptor plate has eventually been installed between the Toyota bellhousing, and Alfa gearbox.

I can supply contact numbers to confirm  my previous comment, should anyone not beleive me......

I have worked on a lada with toyota 2ct motor and lada bellhousing onwards.

The bell housing had to be cut in half, in front of the clutch lever, rolled over 180 degrees and rewelded to the rear half of the bell housing.  This lada has had gearbox problems, but only because oil leaks causing gears to burn and bearings to seize.

Further complications are that the exhaust needs to loosened at the end of the manifold and disconnected at the first connector in the exhaust and then hung on a rope more or less  in position so that the gearbox can be removed or inserted.  Neither the exhaust nor the gearbox can be fitted with the other one bolted in place.

There are / were front diff issues caused by the poor engine mount conversion leading to misalgnment of the bolts leading to them stripping.

The turbo has also been turned down, what it is set to I am not sure.  Due to overheating issues experienced with the Lada radiator it has been replaced with either a BMW 7 series or a Hilux one, I forget which.
