Morris Minor Owners Club

Hi, Many times I had struggled with the Borg&Beck clutch in my Traveller especially if quality is concerned. So I looked for a diaphragm clutch. My Traveller carrys a 1275 Marina engine and a Ford T9 gearbox. The kit for the gearbox came with a 190mm disc. To use this disc I found a LUK clutch 8...

The answer from Mini Spares:

The head was pressure tested and dye tested for cracks prior to porting it.
So the head itself shall be ok.

Chris

Hi Phil, I hope that head is ok and has no cracks. The owner of the car is a friend of mine and had bought the head from Minispares a few months ago after he had driven my car and decided to modify his car the same way. So I guess the head was pressure tested and checked for cracks before Minispares...

The syptoms: a loss of coolant each time after driving at higher revs causing higher engine temperatures without any signs of burned water or water in engine oil lead me to the suspected diagnosis, a possible hairline crack in cylinder #4. That crack will open a bit at higher temperatures and let co...

The head is completely new and fully checked. It has just covered some 500miles. And: the problems were the same with the head previously mounted.

Chris

Thanks Stephen, Yes block and head were skimmed and the head gasket is a new Metro-turbo-gasket. The studs are new ARP-ones in perfect shape. The nuts were torqued down to 65fl lb. I will see next week if there is a damage in the gasket towards a waterway next to #4. We had seen the lower water leve...

Hi, A friends morris with a 1275 engine had 3 head gasket failures one after the other. These happened always shortly after the rebuild when the engine had been driven at higher revs for the first time. It suffers from water loss out of the water cooler cover mostly if the car had been driven at mor...

I dismatled the diff because I wanted to install a LSD and to solve the leaking seal at the entrance. The parts needed were purchased at ESM. I measured the back lash prior dismantling as described in several tutorials. After removing the ball bearings at the diff cage I measured the thickness of th...

It’s much easier to change the seal if the diff is on the bench. The main problem is to tighten the nut correctly and have the correct preload on the pinion bearings afterwards again. The nut must be tightened a bit more than it was before, about a quarter of a turn, but that will increase the press...

@Don, As you asked for an Update: Differential refurbished, follow up. After removing the diff from the axle I removed the nut at the entrance flange first. That was easy as I had bolted two pieces of angeled steel to the flange and clamped these to the workbench. The flange, nut and pinion shaft we...

My nut was about to come loose with a little more power than I could provide with my fingers. That was the sign for damaged bearings. To tighten it I made a pair of angeled steel drilled to measure and bolted to the workbench. That worked well enough.

Chris

Phil,

Thanks for that description. I will torque the nut to 140 ft lbs and follow your recomendation and hope it works.

Chris

140 ft lbs means 190Nm, puh! I thought about torqueing the nut to 125 ft lbs first and see how the diff does. If not good I can torque it a bit more to 140 ft lbs. In that case I can safe the crush spacer on the first hand and do not need to dismantle the diff again to install a new crush spacer. Ch...

I read in the workshop manual that the nut at the diffs entrance flange must be torqued to 140 ft lbs. Is that correct? Seems quite a lot to me.

Chris

Concerning the german Autobahn: it’s not the cars , it’s the people in the cars that make things difficult. And a „run-away-car“ like an Audi S3 has got the same problems like a Morris if a slow going car is ahead. I use the Autobahn extremely seldom with my Traveller but I feel safer in a car with ...

Yes! A Minor is absolutely not a car to go fast on a motorway for a longer time. That’s true. But it’s always good to know that one could do. To go fast I‘ve got other cars but I hate the feeling of standing in one others way. My Traveller is as I like it. A wolf in a sheep‘s skin as is a saying her...

That’s right but with the standard 1098 engine 120km/h at 5000revs is a bit of stress for both driver and car. In my tuned 1275 Traveller 120km/h means 4000 revs in 4th gear and 3600revs in 5th. That’s much more comfortable and a lot better for the car also. Even if it can go 165km/h or maybe more I...

If you simply use longer wires for plus and earth you‘ve got enough room to mount the battery with the poles towards the bulkhead regardless where to poles are. That’s what I did. I can use any battery now.

Chris

Well, my Traveller is an absolutely usable street car but a bit quicker than others. It’s easy to drive and performs well in heavy town traffic. Surely I have upgraded to disc brakes but that was done long before I changed and tuned the engine. All the mods I made are easy to convert back to standar...

„I did spot that and was tempted…. But honestly I have a few other costs to meet before I start upgrading! This will probably be something I’ll get onto eventually… but not yet“ Good idea to keep funds together. But keep in mind those heads are not so easy to get and buying a new ported head is an e...
