Morris Minor Owners Club

there's a morris just advertised on ebay that says: 'converted to timing belt so is super quiet and smooth'.

as mine's quite rattly i was wondering if anyone else has done this and how easy/difficult it was?

I think he may mean duplex timing chain. I have yet to see a timing belt on a minor, other than the twin OHC conversions

I've seen these before.
One magazine did a review of fitting and straightforward.
Try Mini specialists for a source.
Cann't remember price but seem to think it was "ouch" money

Really? I would like to see that done! Would involve a lot of work wouldn't it?
New timing chain (oops belt) cover
New sprockets
And a belt that actually fits, I have never seen any timing belt as small as the chain on an A-series

Had a quick look and found this -

That looks very nice!

Even though this conversion looks nice too:

Very nice but expensive, I'm going for duplex as per ESM - I don't think I worry about the vernier adjustable one.

Belts may look pretty and be quieter but I'll stick with a chain (preferably duplex)

Chains may rattle but they rarely fail.

I've seen a belt break at 14K miles from new

Timing chain noise is part of the "A series" charm

I wouldn't do it either, but it is nice to know that you can, isn't it?

The size of the belt reminds me of my moped engine.

I had considered fitting this type of belt to my 1275cc engine untill the man behind the counter had told me that the oil seals were a week spot, as the oil had to be kept behind the engine front plate ,there are now two oil seals insted of the one behind the bottom pully.
I have since fitted a duplex chain on adjustabe gears with a tentioner from a metro.
so far so good

GAS.

John, mine did...just a few weeks ago and the small gear was in two halves and I missed two teeth of the large gear... costed me 600 euro to repair....

I sold on a belt conversion kit that came with one of my Mini engines. Really no need for this on a road car - and the dodgy seals and the possible effects on the belt of oil leakage made it undesireable for me. Duplex is fine.

Just for info , I fitted a duplex chain to my Minor last weekend. It was from MGM & involved removing two of the bolts which hold the front engine plate in position , countersinking the holes & using the two supplied countersunk Allen bolts . This is because left in place the standard bolts will foul the crankshaft pulley . If the engine is out this is relatively easy , with the engine in situ , I needed to remove the front engine plate . If you do this , you will need to buy the gasket between the engine & front plate or if it is saturday evening you will need to make a gasket from thick brown paper as I did . Good Luck !

I did the same yesterday. Even with the engine out of the car, remove the front plate, unless you want to risk filings going where they shouldn't.

Unfortunately the MGB gears are half a tooth different timing to the cooper S / Metro type , but I dont suppose it will matter much on a road engine.

Where did the MGB gears come from ?? Did I miss something ?
Even when using the c/sunk screws you still need to be careful. Some duplex chains have a joining piece with slightly longer pins through the chain. If this is fitted with the extra length towards the engine - they can rub/catch/be very close to the c/sunk screw heads - so it's importamt to fit the chain with these longer legs facing away from the engine front plate.

Yes, I agree, better off with a chain, timing belts + Moggie leaking front oil = valves hitting pistons!

Oh I don't know - Belts can bne OK on an A series apparently ;)

Wow, Packedup...what is that for an engine ?... does that go in a Minor ?

that looks like a twin cam 16 valve BMW head put on top of an a series.

Might go in a Minor or Mini, or really any a-series engined car
