7 + 7 = Donor car found...

I've been looking for a donor car for a while now and finally found one - 1978 white auto with a black/red check interior (result!) which has been parked in a garage for the six years with a fuel leak problem.

It has a V5 and on Sorn and only £200 + pickup costs!

There has been lots of welding under the bonnet and all the usual rusty bits, but lots of good parts and trim.

Black and white...

You can easily see the difference with first carb reassembled - second carb now stripped and in the cleaner doing its stuff...

Ten pounds well spent!...

Turns out that the suspect ultrasonic cleaner wasn't Fairy Liquid after all – couple of hours in the cleaner at 45-50° heat did the job.

The body of the carb took the longest, after about hour I removed it and using a nylon brush I loosen some of the stubborn bits.

The heat makes a vast difference, previously I've allowed the fluid to heat itself i.e. the ultrasonic action would heat it but not to a high temperature.

Looking good - now for the other one.

Carburettor strip and clean...

With the inlet manifold nice and clean, time to tackle the carbs - twin SUs covered in thirty-six years of crap and grime.

Decided to get some "special" ultrasonic cleaner, 1ltr concentrated engine component formula - wasn't sure if I had just paid £10 for a litre of water and washing up liquid!

I started by taking these photos to remind me how they should look when putting back together – I have a pdf version of the workshop manual (on my useful links page), so print off the carb section pages and put them in a clear page file which I had already done for the engine rebuild.

I split the carbs and thought doing one at a time was a good idea, putting them into two containers marked left and right.

With the first one stripped off to the cleaner and the Fairy Liquid!

Inlet manifold...

Next item in the parts box was the inlet manifold - removed the blanking plate, plug and non-return valve (brake servo) and power washed it.

After giving it a good soak in degrease and power washing all the waterways. I noticed on the inlet hole on the carb side was a small lip where the original machining hadn't gone deep enough. So with a half round file I removed it to allow better flow (maybe?).

Then I finished off with a couple of coats of high temp aluminium paint.

Camshaft cover paint...

Decided on silver for the cover with black "Triumph" wording, cap and sleeve nuts. Two coats of silver and looking good.

Next, I just need a steady hand for the lettering...

Engine stand...

Been busy with work and visiting universities with my son over the last couple of weeks, so only spent the odd hours getting items ready for the rebuild.

I give the sump pan its first coat of paint which now rubbed down for second when weather warms up.

Striped and cleaned oil pump and filter bowl which has had a first coat of paint.

Also clean and prepped some parts for blasting - engine/gearbox mounting brackets, gearbox crossmember, tie bar and other odd items.

Also fixed the engine on to the stand - lifted into place easily and with ability to the spin the engine allows good access.
