1969 Traveller - 1275 engine - what clutch do I need ?

[williamraff]

Can anyone advise if a standard clutch kit will be ok to fit to a 1969 traveller witha a Marina 1275cc engine?
Many thanks,Will .

assuming that it has the flywheel etc to match the standard starter motor then yes. however, as someone who could (before switching to a five speed gearbox for their traveller) change a standard 1098 gearbox from start to finish in 1 1/2 hours, i'd recommend that you upgrade the rest of the drivetrain suitably. otherwise the 1098 clutch will slip, then when that is replaced with a 1275 item the gearbox'll be out shortly etc etc.

Hi, many thanks for the response. I am not sure what flywheel the car has got, I am picking it up tonight but I am aware that it will need a clutch.
Can you expand on upgrading the drivetrain? Do you mean it should really have a bigger box in it?
Also -1/12 hours to take a gearbox out sounds quick - any tips do you have a ramp? I will be working on the floor.

Many thanks,Will .

unfortunately you will need to take the car to bits to know what clutch is has, this is the problem with 'upgrades'. a fairly common problem on upgraded minors is who did the upgrades and with how much actual talent, but this'll become apparent as you learn your way around the car.

my 1 1/2 hour gearbox change was done on axle stands in the open, it's all a matter of practice.

as far as upgrading the car goes, the standard 1098 puts out 48bhp. the gearbox can 'just' about take that, but the gearboxes on morrises and equivalent engined austins are rubbish. my own experience involved the loss of second gear after fairly short periods owing to the motion shaft going, which meant going down to 3 gears. this happened initially with my 1098, fitting a 1275+ engine from an mg midget only quickened the rate at which the 'boxes went. to start with i kept the 1098cc clutch (which quickly just started slipping) replacing the clutch with the 1275cc item then led to eaten gearboxes. hence my ending up with a CS Autoclassics 5 speed using their bespoke bellhousing to a ford type 9 gearbox, this went through a shortened prop to a triumph dolly axle with a 3.9 diff in it.

Sounds pricey and time consuming - both of which I have little of. Picked car up tonight, got it home 50 miles but clutch and gearbox are ruined, noisy diff and engine is knocking / rattling and does not want to tick over. I know how to pick em! .
I am thinking stick a 1275cc clutch in as the engine in its current state of tune would not pull the skin off a rice pudding and run the existing box until it gives out completely.
Looks like I am on my back for the forseeable then
Cheers,Will.

Hi,
I'm having probs at the mo with my 1275A+ engine/clutch. My clutch slips but only when cold(strangely).

It has a 1098 box and a 1098 clutch.Is there a compatible 1275 clutch that will mate to my flywheel?

Many thanks in anticipation

No you need a 1098 clutch......

Hi Gang

I need your advice oin Clutches with the 1275 engine

I upgraded by Morris Minoir 1000 from a 948 to a 1275 when the enigne developed a rod knock

My ribcase is a 1098 rebuilt with about 15,000 miles ago and has run fine since

After the installation, my pedal was extremely heavy and both the pressure plate and disc broke after only a few miles. I though that it was defect and installed a seocnd cluthc kit and it broke agon

There are two othger posts from club members who have had the same experience with heavy pedals following an intallation of a 1098 tranmsssion. One whose plate and disc broke like mine

I am wondering if the 1098 disc might be a little thinner than a 1275 disc. Does anyone kow if I could use 1098 disc with a 1275 pressure plate. i think I read a post where a member had done that but I cannot find it

Whether or not it is applicable to the questions, here goes.
The easiest conversion is the 1275 Midget engine and box. The box dimensions are exactly the same as a 1098 box so if that is the only box available then it will fit. Some say that the 1275 box is no better than the 1098.
On the subject of the clutch, the 1275 is fitted with a 6 bolt flywheel instead of the 4 bolt on the 1098. The clutch plate is a smaller diameter than the 1098 but larger than the 948 and is of course a diaphram type. No problem, just fit the 1275 complete with clutch.
The only modifications required are to the linkage. A wise move is to fit the ball bearing thrust bearing conversion as the extra load on the diaphram clutch plate will greatly shorten the life of a carbon thrust. That just leaves the pedal weight. If you use the standard linkage you will have an in-out clutch and develop weight lifter's leg muscles, great for circuit racing but no good for the London commute. The solution is to lengthen the arm on the relay shaft that connects to the pedal linkage by 1 inch and redrill the hole accordingly. This will give the weight and travel of a 1098 clutch

The only reason to 'lose' 2nd gear - is by rough treatment on up and down changes - not using double-de-clutch. The box will be fine with a standardish 1275 engine - provided some reasonable care is taken...... However - I don't see any point using the 'knocking/rattling' 1275 engine - it's only going to get much worse. I believe you should grasp the nettle and buy a cheap 1098 (or even a 948) engine and box in known 'running order' - and fit that to the car while you overhaul the 1275 engine/box etc etc. That way you will be mobile - and can take time to sort out the ailing 1275 units.

I agree with BMC here (even if he does think I'm foolish! )

My '69 Minor has been running with the original 'box and 1275 Ital engine (and HIF44, LCB, 3.7:1 diff, Metro dizzy etc) for 18 years and the 'box is no different now to when I first upgraded. I only double declutch if needing to change down into first, which isn't very often.

It is important to remember that these boxes won't take kindly to being driven in the same way as a modern car. I don't thrash mine and it's as quiet and good on the syncro as it was in 1991. The clutch is of course also standard 1098.
