Rusty Triumphs in Scotland

New video of my poking great fuck off holes in important structural elements of my car.

Looks like you've got James May's shirt collection.

No idea what you're talking about...

Changed the Acclaim's timing belt with the aid of a chap on the Beige going by GingerNutzz.

It was two teeth out and probably had been since the belt was last done 4 years ago before I bought the car... It's amazing it ran as well as it did! It was a bit of a bastard of a job though, I couldn't be arsed filming/photographing it but it was essentially:

Jack up car and remove passenger front wheel
Support the engine with another jack
Slacken the alternator bracket and remove aux belt
Zip off the crank pullet nut with an impact wrench, Remove the pulley, try not to loose to tiny woodruff key
Undo the passenger side engine mount and shuffle it out of the way
Undo the rocker cover and remove the upper cam belt cover
Take off the water pump pulley as it get's in the way of some bolts for the...
Lower cam belt cover, un-bolt and remove
Now you can slide the old belt off.
If you're like use you didn't bother to set TDC before this point, so refit the lower cover and a the crank pulley so you can align it properly. Then remove them again.
Un-bolt one of the tensioner bolts to allow for fitting the new belt, remove the funny little spring that doesn't seem to do anything.
Align the markings on the cam pulley to be in line with the surface of the cylinder head
Fit the new belt
Wrestle for a thousand years with refitting the tiny spring that doesn't seem to do anything
Bolt up the tensioner
Put the water pump pulley back on
Go to fit the lower cam cover and realise one bolt hole is behind the water pump pulley, elect to pretend it doesn't exist and fit it anyway. You now have one spare bolt.
Put the crank pulley back on - This is a faff due to the tiny woodruff key
Fit upper cam belt cover
Refit engine mount
Replace aux belt and tension with alternator bracket
Start car, run up to temp and set ignition timing with strobe light
Readjust idle speed and notice your airbox is full of oil. Great, that's new
Realise car is running way too rich and vow to fix it another day

Car now goes like fuck from a standstill and holds constant speeds on the motorway with far less effort, it also idles way smoother. Still bogs down under heavy throttle but if it's running rich is might be flooding. Need to sort when it isn't pissing it down.

Can't believe the fucking belt was so far out, I've been assuming that it had carb issues for the last 15,000 miles. Seemingly it was just because the PO couldn't grasp the concept of lining up the cam sprocket marks horizontally to the cylinder head... Given the quality of all the other work he'd done to the car I should have guessed I suppose.

Mr Nutzz also has form for Triumph tinkering, as this ongoing nut and bolt rebuild of a Herald will attest to...

Hotted up 1296cc engine running Honda bike carbs (descendants of the Acclaim's twin carbs no less!), sounds fantastic and it's not even properly tuned yet...

Two teeth out is nearly OMGVALVEBENDING I'd have thought!

I'd only add one thing to your list of how it's done - turn engine over by hand a couple of times to make sure it turns. You really don't want the noise of valves hitting pistons when spinning on the starter if you've done something silly.

Like leaving the locking bolts in an XUD engine......

Breaks the cam first rather than anything else. Just in case you ever need to know

Our V6 omega was a tooth out on one cam when we changed the belt. Didn't go any better or more economically and it certainly didn't fix the awful electrics getting it right.

Cambelts are shit. Chain drive for peace of mind.

Only in real engines, progress* has made chains just as shit these days. I think it was BMW who fitted them at the back & made them fail quicker than a boot.

[CLINT]

Yeah Nissan have the same design in the X Trail which has made the cars disposable rather than fixable.

My mk2 cav 1.6 petrol slipped the belt during some enthusiastic motoring. I could pinpoint the nanosecond that it happened. exiting the M4 eastbound at J 8/9 just as I selected 3rd it went thud. Car ran but not nicely. Drove it it 20 miles home and then 50 miles back to work the next day. Friendly mechanic told me the belt had slipped one tooth. no idea why...

Stag v8 will not cope 1 tooth out on the chains, the engine will catch a valve when winding over by hand!

Glad you got it sorted after watching that video you loaded trying to get the covers off
