Morris Minor Owners Club

Hi Don,

Excellent work. I will review the information provided on this post and get back soon.

Thanks for your effort !!

The section of the mono construction book covering the Morris Minor chassis/body assembly was reproduced in a Car Body Manual published in Australia in the 1950's. I am happy to send a scan of this to anyone interested.

I used POR15 to restore the front suspension, rear springs and many other parts. It is important to follow the instructions, first clean with Marine Clean and then treat the surface with Metal Ready, wash and dry before applying POR15 rust resistant paint. The result was excellent as POR15 spreads e...

The Sri Lankan made panel is the nearest to the original available commercially but the panel installed by BMC on genuine Convertibles had a raised section to give added strength. See the original panel developed by Taupe on the following thread: http://www.mmoc.org.uk/viewtopic.php?f=28&t=25298...

The sill strengthening panel supplied with conversion kits is simply a folded 18g steel sheet to be welded outside the sill. The original Convertibles had a panel welded inside the sill of a complex shape with raised section to give additional strength. I have been trying to get information on this ...

I tried to solder 28/0.30 cable to the field coil end and found that it is too heavy for solder to hold. After soldering the bonding broke off when the cable was moved slightly. I trialled with few different sizes and the photograph below shows the heaviest gauge 25A cable tried and on the right is ...

Thanks Bob and Roy for the advice. Yes, I will use Castrol LM grease and look around for 28/0.30mm cable. I checked the old Lucas recommendations and found that the original cable is 28/0.012" of which the current metric equivalent is 28/0.30mm. Thanks again.

I prefer to use the original 7" drums and I read on another thread that wear on drums up to 1/16" is acceptable. I note that the second drum has just exceeded this limit.

I recently took a series of measurements of the brake drums using an internal micrometer and the average diameters of the 4 drums are as follows: 7.027” 7.077” 7.037” 7.036” For some reason, the wear on the second drum is greater than the rest. What is the wear limits on brake drums? Would brake sho...

I cleaned the wiper motor by glass bead blasting the main body, aluminium base and end cap, gearbox cover plate and parking switch cover. The main body and other steel parts were protected by applying POR15 paint. The final finish is as shown below. I still need to select the correct cabling and the...

As the cable originally used is rubber insulated there was a recommendation in a forum on the internet to use a flexible cable rather than stiffer PVC insulated cable. I don't know the exact reason but it could be not to over stress the terminal on the parking switch cover. From a Lucas technical pu...

Thanks for the responses. I have been looking at suitable cables to use and found the silicone insulated cables to be the best as they are more flexible than the standard pvc auto cable. How much current is this cable required to handle? Can this current be safely handled in a slightly smaller cable...

Over the next few weeks, I hope to refurbish the Lucas DR2 single speed wiper motor shown below. As I understand, the procedure for adjusting the wiper parking position is by rotating the parking switch cover. As the cable from the field coil to the parking switch is very short I find that it does n...

I cannot comment if the original MOWOG pins were case hardened after machining, but it is unlikely that the replacement pins manufactured now are case hardened. The pin on the right of the picture is anodised or chemically treated after machining and definitely not hardened. I don't believe the pin ...

I just found that the 17mm pin is meant to be used with replacment bottom trunnions made in India. These trunnions have a bush diameter of 16.9mm and I was advised to 'ream' the bush to 17mm before fitting the pin. This I guess is part of going metric. I purchased the Indian trunnions and pins durin...

The pin on the right is not a genuine item, a new replacement for the Minor. I measured the diameter of the new pin with a vernier caliper and it is exactly 17.0mm. The trunnions I have are genuine MOWOG and this pin does not fit. Does the new replacement trunnions have bushes with slightly larger ID?

Pete, I found the damper drawing in a book on car suspension systems. I scanned it myself to share with others. Thanks Phil and BMC for the responses. It is possible that the new pin I have is slightly larger than the original. I will measure the diameter and also check pins available with other sup...

Phil, Thanks for your response. I noticed that there is some wear on the original pin but the trunnion bush appears ok. The pin on the right is a new replacement purchased recently and I found that the trunnion bush needs to be reamed to fit the new pin. This suggests to me that there is minimal wea...

Many thanks for your responses. I myself was surprised to learn that fibre washers were used on fulcrum pins. I will certainly reuse the original thrust washers and pins as they appear to be in good condition. I believe the reason for the screwdriver slot is to prevent the pin rotating when tighteni...

On the left are original steel thrust washers and a used original fulcrum pin for the bottom trunnion. I have been told that BL later changed the material of the thrust washers to hard fibre to prevent the wearing of the surfaces of the trunnion in contact with thrust washers. On the right is a repl...
