Morris Minor Owners Club

I totally agree with Phil's comment. ESM can supply new piston ring sets from standard size through to +60 for the 918cc Side-Valve Series MM Minor.

Many thanks for this information. Would you know if Lincolnshire Archives would release that information. Well that's what all County Archive Departments are in existence for, they're a depository for historical documents, company archives, old newspapers, photographs, maps etc pertaining to each C...

The registration JJL 857 would have been issued between February and June 1956 in the Holland district i.e. Spalding area of Lincolnshire. Apparently the original registration records between 1932 and 1972 still exist and are held by Lincolnshire Archives - link below: https://www.lincolnshire.gov.u...

Forgot to mention, ask the company to crack test the crankshaft before starting the job.

ESM can supply the bearings ... and a number of classic and vintage car engine reconditioners / engineering companies are listed on the Old Car Services site. I would also suggest buying a copy of The Automobile magazine as a number of well known and highly respected classic and vintage engine recon...

ESM have valve springs in stock for the Series MM Minor 918cc side-valve engine - their code number: SV103. These are identical albeit new to the S/H Morris 8 springs Philthehill mentions above. https://www.morrisminorspares.com/engine-c14/918cc-side-valve-engine-parts-c17/valve-springs-each-918cc-s...

The N.E.R.C. is more or less on your doorstep if you need local help and advice. Some of the members probably live in or around the South Shields area - certainly I can think of one or two that did back in the early days of the the club in the 1970's when I was a member. http://www.northeastrestorat...

I've neither bought one nor fitted one, so absolutely no knowledge / experience of them, but these 'DYNAMATOR' - 45 Amp alternators that look like the original Dynamo and fit using the original Dynamo mountings are available here in the UK - though some would say they're expensive. I presume the Ser...

The original spec for Series MM valves were:
Head Diameter: 28mm
Stem Diameter: 7mm
Stem Length: 89mm

I've found another couple of online images which might suggest that the blades in photo 2 of the MM water pump in my previous post are in fact the correct blades for the later water pump engine and the blades shown in photos 1 and 3 are for the earlier non-water pump engines. Note that the leading e...

Rob, I've a 918cc Morris 8 Series I Tourer rather than a Series MM Minor though I do have a Military Tank engine which as I'm sure you'll know was built around the late MM Minor water pump / external oil filter fitted side-valve engine block. None of these images are mine, I've merely found them on ...

A single fan blade was fitted to the late 1934 to 1948 Pre-Series / Series I / II and Series E Morris 8 side-valve engines. The BMC Morris Series MM Minor Service Parts List Fourth Edition seems to suggest that the two blades I mentioned in my earlier post - X31437 / X31438 were fitted to the early ...

The parts list shows that the two blades are indeed different: Blade Fan - part number X31437 - illustration A80 - 1 required Blade - Offset - Fan - part number X31438 - illustration A81 - 1 required Also check that your blades are fitted the correct way round i.e. sucking air through the radiator n...

The Morris Motors / BMC Series MM Minor Service Parts List suggests the following: These are Morris Motors part numbers. Sump Drain Plug part number: X31479 - Washer p/n: 6K432 Gearbox Drain Plug part number: X31479 - Washer p/n: 6K432 Gearbox Filler Plug with baffle part number: SA1340 - Washer p/n...

I'm reasonably certain the following screw-on oil filters will be shorter than the one you've received with the adaptor unit. Google these reference numbers and you should be able to find out the filter length.
Crossland 547
Fram PH 2834
Mahle OC 4

It's highly likely the drain plug of an MG T Type and MG Series Y will be from the same Morris Motors / Nuffield Organisation parts bin. Certainly worth checking for size if you happen to live near to NTG Motor Services Ltd in Ipswich or a Moss Europe branch in the UK - London, Bradford, Bristol and...

The sump bolt on the left with the deep head is a genuine original and the sizes would have originally been:
The two front and two back sump bolts M8 fine (1.00mm pitch) x 22mm (7/8")
The eight other sump bolts M8 fine (1.00mm pitch) x 19mm (3/4")
The heads were originally 3/16" Whit / 1/4" BSF

Thanks Taupe - bookmarked for future reference, some interesting products.

Follow VERY carefully the instructions regarding the fitting of the rear main bearing cap Cork Strip - section A.2 Removal and Replacement of Sump pages A.7 and A.8 of the British Leyland / BMC Workshop Manual (14th Edition).

Taupe,

I'd be interested to learn where you sourced the 1/4" BSF threaded brass inserts - they look useful fixings for timber framing.
