Leyland-Thornycroft Diesels

[John_Hampton]

I have recently bought a boat powered by 2off BLMC 2.2 Diesels. On one of the heat exchangers on the top of the engine (The long aluminium castings with the words Leyland-Thornycroft on them) the blanking off screw (approx. 25mm dia. is missing, unfortunately the plug in the other engine will just not budge for me to remove it to have a copy made. Has anyone got one or know where to find one from?

Also need an oil pressure switch/transducer which screws into the engine block.

I am changing the mechanical gearboxes marked 'MOWOG' so if anyone needs one/a pair please email.

I think you will find that the plug is a standard 1" taper iron plug which can be obtained from a good plumbing supplier.
Most other stuff is still available for these engines although some bits are getting a bit difficult to find now.
ASAP supplies are good for senders etc.
Best of luck,

Thanks Sammy
I will try local plumbing suppliers tomorrow, just to clarify, this is the plug which screws into the top face at the heat exchanger.

Thanks Mike
This site appears to be for new engines rather than my 30 year old ones.

Hi John,
Yes all the outlets should be BSP thread either 1" 3/4" or 1/2.
If you really want to get the old one out try heating the casting first.

The web page was to give you the phone number. I too have 30year old Thorneycrofts and I buy all my spares from them.

You should be able to purchase the blanking plug at any plumbers merchant, it's more than likely a 3/4" BSP Taper.

Thanks Sammy, I will take blow-torch with me at the weekend, remove existing plug and replace both.

Thanks Mike, will check website for phone number for future use. The boat we bought came with 2 fitted engines, but these had never been plumbed in (No electrics, fuel, exhausts, throttles etc, the previous owner having removed & refurbished them, but for personal reasons walked away from the project). Whilst looking through the tons of bits we received with the boat I have found 2 brand new oil pressue gauges complete with transducers and different sized adaptors to fit into the block so that problem at least is solved!

Thanks Mike will buy 1" + 3/4" and arrange to take back unused one.

John, 3/4" BSP has a major dia of 1.041" (26.44 mm).
