Matilda

[George Moore]

Another plea for assistance coming up !

Does anyone have some good photos of the Leyland engines fitted to the Matilda's.

I have a great set of photo's for the AEC, (thanks), but now need to see how the Leyland engines looked.

I have drawings from manuals, and the publicity shot from the manual, however the sides of the block are the unknowns.

A shot of the gearbox would also be very welcome, again I have drawings but need to "see" the shape.

Any help much appreciated.

George.

Not insitu, and not complete, but it may kick things off for you.

Is it a Leyland 680 derivative? Maybe George you could look in that direction?

Hi Guys

Please see attached details

Engines are 7.5 litre

As a general rule, Matilda I and II are fitted with twin AEC engines (A183 and A184). Matilda II* (IIa), III and IIICS are fitted with twin Leyland engines (E148 and E149 or E164 and E165). Matilda IV, IV CS and V are fitted with twin Leyland engines (E170 and E171).

All lower numbers are the left hand engine.

The Leyland engines are all the same bore and stroke however the mounting and layout of auxiliaries are different.

Early engines have aluminium sumps, later types have pressed steel sumps as it was found that when the floor was bulged up as a result of a mine blast the aluminium sumps fractured resulting in engine failure.

I have seen some engines with cast sumps but they are few anf far between.

Kind regards
Matt

Thanks guys, just what I needed.

I should have mentioned that I was needing photos of the engine and gearbox "out" of the tank, these are just what I need to show the shape of the block etc.

One query, the oil tank is mounted on the "outside" of each block, I see one of the photos has it mounted so it would be between the blocks, is this just to show things part assembled?

The later engines are listed as "improved Leylands", these seemingly had the oil tank attached, plus other additions such as oil cooler tubes running across the gearbox end of the blocks, improved filters etc.
Wasn't aware of the sumps though, thanks for all the info.

The manual for some reason has sectioned drawings of the AEC engine, which are useful, but strange in that the sump on the drawings is totally different to that fitted on the tank engines. The most obvious difference between the AEC and Leyland (there are others of course), but at first glance, the Leyland has a much wider and flatter rocker cover. I did not realise that the rocker cover came apart either, thanks for that.

If there are other photos, please send them on.

These really help, and thank you all very much.

I cannot get the link to work (?) but should you wish to see some of the model work I have done, look at www.mooresmilitarymodels.co.uk

Thanks again.

George.
