Fitting a 1275 Engine! Jons dubious guide.

You REALLY don't like alternators, do you...

Yes - it's personal (3 times left stranded due to the infernal devices)

Worse case you can always change to an electric fan with a sender in the top hose...

Dunketh - the heater tap problem is well know - I mentioned it again just a few days ago - and the thermostat pointing is also well know. But very well done getting the conversion in there - I just wish I could find an engine - in fact a block would do - i have two spare cranks in stock !
The easy answer with the timing cover is - fit the old one ! And use the rocker cover breather - the engine then also looks pretty much standard except to the trained eye of course!

Just in case you missed it the first time round

On the Marina/Ital 1275 they are at about 11 o'clock looking from the front whereas on the 1098 Minor engine they are at 6 o'clock. You CAN of course cut a new notch in the 1275 pulley but you'll have to be spot on with it and I don't recommend it for the following reason: It was deemed that the 1275 needed a FRONT engine breather so that's why it has one. If you put a 1098 front cover on then you'll not have a breather and that could well lead to oil leaks. Also, if you have a timing chain tensioner (as a lot of 1275s have) then you'll need to get rid of it or the 1098 cover won't fit!!

My advice is to cut down the canister and weld a flat section onto the front.

Thanks - didn't see it first time around. For me - timing marks are waste of space - never use em! My 1275 Mini engines all have flat timing covers with no 'can' - and no oil leaks (well, no more than any Mini!). Yes - if you want to keep the tensioner you need the big cover - but far better to run duplex - and a flat timing cover !

Well, yes you CAN do without them but it's much easier setting static timing with them so you then have a reference point to start playing with. Of course dynamic timing is impossible without the marks.

Yes, Minis do leak a fair bit (well mine did).

Agreed. That's what I have on my 1380cc Ital engine.

Have stripped down 1275 to inspect and started mods to engine breather. Inside the canister there was a mass of shrapnel which presumably acts as a strainer, what have others used to replace this, would wire wool be too fine?

My choice would be to do away with it - cut it off and weld a cover over the hole - or just run it empty if you really MUST keep it. Any oil is going to condense in there long before it gets up to the engine. Better still - use the old style flat cover with duplex chain.

The transverse 1275 has a breather on the transfer/ drop gear housing, which of course the inline version doesn't.

Post by **Cam** » Wed May 03, 2006 1:36 am

Just remove the 'wire' mess and leave the canister empty.

Post by **246gts** » Wed May 03, 2006 9:01 am

Thanks Cam

Must try and fish out the wire wool now Ive welded it up!!!!

As long as it's not restricting the breathing too much you could leave it in I guess.

Post by **bigginger** » Wed May 03, 2006 1:27 pm

It'll rust though, depite having oil on it...

Post by **Cam** » Wed May 03, 2006 6:24 pm

Yes, better without ideally.

Post by **246gts** » Thu May 04, 2006 3:05 pm

Job done, canister empty

I feel its something that would be of value to minor newbies. I had to search all over the place for the info I needed and certain bits like differences in stat housing and water tap weren't mentioned anywhere.

They are all mentioned along with lots of other useful info in Owen Burtons book Marina to Minor its not perfect but does advize on all the more common adjustments including the midget engine as well.

Just one other thing how did you manage to fit the engine stead without notching it to clear the heater valve.

I also did a post on fitting a Midget engine
http://www.morrisminoroc.co.uk/index.ph ... get+engine
I also think that Andrews suggestion of a useful tip on fitting the engine but making it into a locked article for all to read would be a good idea, without it being open to going of topic..

There is enough thread on Joe's engine to put the bracket over the nut and then add another nut on top. This is also useful in that any replacement of engine or steady bar in the future doesn't involve slackening all the cylinder head nuts (to prevent warping).
