Fitting a 1275....

[youngun]

Just been musing over the idea today.in essence what is required to fit a 1275 engine (other than the engine obviously) to in my case a 948 saloon?

I am assuming a Marina / Ital 1275?
First off I'd go for a 1098 box at least to go with the 1275. This allows use of a bigger clutch and you also get a stronger box.
You need to use 948/1098 front plate and 1098 rear plate. Top dowel will need opening up to allow back plate to fit. You may have to machine opening for oil pump (depends on which pump you use) Crank rear main will need opening up on back plate also. Flywheel will need to have fixing holes drilled out to suit the 6 bolt fixing on the 1275 crank. Last thing I can think of is to space out the starter motor dog gear to clear the flywheel.... There may be a few more little bits but I think thats the main part of the work...

Change the diff ratio too!

Have a look at my website just put a 1275 A+ from an ital in my series II www.morris-1000.co.uk

I have a comprehensive guide if you'd like one.
Started off a bit rubbish but I've been back and corrected it over time.

Simple word doc or PDF, pm me your email address if you'd like a copy.

Eugggh sounds like an awful lot of work. I might try and find a Spridget 1275.

[bmcecosse]

Doesn't make much difference - still need to do most of the work !

[youngun]

What about if I have access to a midget engine and box? Surely that cuts out some of the work?

Indeed - just need to convert the clutch to operate from the Minor rod system - which some say works very well!

[mike.perry]

No need to change the clutch system, just carry out my modification.

[bmcecosse]

Well - that's what I meant Mike !

[mike.perry]

I think we could do with a section where instuctions for various tasks that are repeatedly asked such as 1098 to 1275 engine conversions, clutches etc. can be published, like on the MM website, so that we don't have to keep repeating ourselves and people could look them up. That would just leave the really awkward problems to think about.

[dunketh]

You're suggesting a FAQ?

I dunno if 'Technical Tips' already covers this though you have to be a paid up member to access some parts iirc.

[mike.perry]

I envisage a forum of Tech. Info where someone who considers themselves an expert on the subject can submit a set of instructions and for a limited period others can submit comments or corrections. The original entry can then be finalised taking the comments into account.
There would have to be a forum disclaimer stating that people undertake it at their own risk. See disclaimer on Series MM website Tech. Info.
Any comments?

[dunketh]

Sounds good. You could take it further with 'Technicians' earning a rating. No text entry to avoid abuse, just a stars or minuses type thing.

Thus avoiding the bodgers like me giving potentially dangerous information to newbies.

[Peetee]

Sounds good to me - although I think we've been here before and it all wnt dead cos someone shouted "liability"

[mike.perry]

That is what the disclaimer is about. Read the Series MM website Tech. Info. http://seriesmm.mmoc.org.uk I don't think the liability is any different from this website where some duff info is given out. You takes it or you leaves it. Its your choice.
I would say that if it does get off the ground then the instructions given should be clear, concise, with correct grammer and spelling and proof read to remove typos.

[bmcecosse]

It could all just be held as a 'sticky'.

Hi you wonderful people. Help needed, again!
I have bought a traveller (Jodie). It has a 1275 sprite engine, a Marina Bell housing and a Toledo overdrive box. I have found these things out for myself by looking at various manuals and the original bills for the conversion.
However it has been plagued since I bought it by limited clutch travel leading to graunching into first and dragging in heavy traffic.
I have replaced the master cylinder seals, they were triumph 3/4 diameter.
I set off to replace the slave cylinder seals but I have found it impossible to remove the slave cylinder. The Marina Haynes says remove the push-rod and pull the clutch lever back to allow the cylinder to fall out. This wouldn't happen.
I then used a screw to push the clutch lever back but could only use the slave cylinder as a pushing point. Trying to sprag the clutch in the release position I succeeded only in dropping a piece of bar into the bell housing.(don't laugh). So now it is engine out.
My question, at last, would anyone know for sure what clutch I would need as a replacement. Is it a 1275 clutch or something from a Marina, or a toledo.
It is my everyday transport and I don't want to spent too much time off the road, if possible.
Thanks

The general rule is that you would use the clutch that goes with the gearbox. I assume the Marina bellhousing is only acting as a "go between" and not performing any function other than a mounting point for the hydraulics. However, I don't know if a Toledo clutch will fit a sprite flywheel - unless the flywheel is Toledo also....?
