Tis normal practice to run duplex without the tensioner, and they are nearly always a tad slack too. and a little noisy !!!

Yes, Huey rattled like a chain smoker. I'll be glad to get rid of that noise at least.
The head is being cleaned and we'll try to spruce the block up a bit.
More Friday, hopefully.
It's taken a month so far!
Thanks for your attention

+1 for crank position sensor. Thats the conclusion I came too when I asked the same of mine.
My pulley had another disk attached to it with 2 notches cut in it which ran perfectly in line with the extra bit

nice work ! will be watching this

[Teapot]

Not much to report since the next lot of parts haven't turned up and we want to get the diff housing back on before stripping anything else off the block and cleaning it a bit. Also, despite putting nuts and bolts in separate boxes and trying to divide areas of the bench for different parts, we're in danger of getting muddled. So ....


As stated previously, the redundant servo was due to come out. We first stretched a bit of rubber glove on the reservoir to block the air vent in the cap and hopefully deter fluid from spilling everywhere.


The upper pipes to the servo had to be disconnected and the lower ones joined up ...


... like this. Hardly any fluid was lost and the brake pedal still felt firm. The brakes will be bled later.
(I wish my camera had a no-rust-colour setting)


The pipe on the inlet manifold has to be blocked off ...


... and since the fitment was a make-do mixture of threads, Doug will machine a new bolt

More next week, hopefully. Thanks for comments, especially clearing up the crank sensor puzzle.

You can buy a grub screw, in fact i have a couple floating around in my centre consol as they were like 10P each or something so bought a few

You might find the timing chain cover mismatch was because it's out of a Metro that carried an engine donor card. The Metro cover fouls the fan, afraid the one you fitted looks like a Metro one too

Mini one showing fan clearing flatification, expect your mechanic mate can do a similar modification

p.s. the lil bracket remains a bit of a mystery, it's not used on Metros either. Best theory is it's used by the factory somehow




pps the manifold bung should be 5/8unf, try the water temperature sensor to confirm.

Cheers for that .. the fan already has a spacer washer (why? dunno unless there was originally a breather on the timing cover) Anyway, it doesn't appear to foul the breather

Correct!

Santa came to call


Plus another exhaust valve somewhere makes 4


Also, the head looks a bit cleaner noiw

Great rebuild thread :)

Great rebuild thread :)

Thanks. Please bear in mind it's not The Ultimate And Total Truth, just me watching Douggie and recording what I think is interesting (in my anorakky way)


The new bearing on the pinion side is tapped into place


Cleaning old gasket off one drive shaft side cover (that's my job )


The new pinion and diff back in place


The gear linkage oil seal is replaced

On goes the diff housing


Not forgetting the tensioner spring & piston ...


... or the gaskets top AND bottom


Taking the burrs off a rather battered driveshaft side cover


The first cover goes back on the side with the tensioner.
The oil seals are renewed both sides


measuring the gasket, shim & gap between cover & diff housing to work out the correct shim ... .15mm IIRC


All the bolts are then tightened in strict order to correct torque settings to keep the drive shafts located
and to avoid stressing the casing. Finally, the lock tabs are gently bent over.
Must be time for a cuppa

[Teapot]

Meanwhile, it's just me and my toothbrush to beat the grime ...


... and it's beginning to look better. The drill and wire brush isn't much help. NB Do not use on alloy


Starting to rebuild the head, the oilways are blown clear


But Dougie has decided to machine all the shoulders of the new exhaust valves
to the same satin finish to equalize performance ...


... and then spotted badly pitted rocker tips and worn shaft, so after debating the expensive option
of getting roller rockers to give an extra few bhp, decided to swap whole assembly for the upper one in the pic

Removing the oil pressure relief valve retaining bolt to replace the bullet with a ball revealed ...
a ball already in residence. However, there were 3 washers on the bolt, reducing spring pressure, so 2 were removed.
This engine is such a mixture of good workmanship and poor finishing, I think it was built by a committee


Marking the distributor position against the block before removal. It's probably working at maximum advance but is coping ok,
so we'll decide whether to change it when we get Huey back together and rolling roaded


One way of getting extra leverage ... but only for undoing, never tightening!

I had to modify my breather due to the fan hitting it on both my 1380 builds. Im surprised yours is not hitting!! here are a couple of pics of what I needed to do..

Yep, I saw that in your excellent build thread pinned in this section. We must be missing something and need
to find it before the engine goes back in.
