MG MGB Technical - gearbox steady bush

Hello
Can anybody advise me how to fit the two gearbox steady rubber bushes (AHH7854) into the upper (AHH8431) and lower steady brackets. I have tried pushing and pulling & used washing up liquid but they wont go through.
Any help appreciated)

Tim. Somewhat difficult to do, but made much easier by a couple of things.

First, get a common screwdriver and give the front of the blade (where it engages the slot in the screw) a rounded profile. Somewhat hemispherical, but exactness is not necessary. Then, polish out the front edges to make a tool that will push the rubber through the hole in the mount without damaging the rubber.

Second, clean all of the parts well. Even new parts can have grease or oil on them. Clean the parts and put a light coating of silicone grease around the hole(s) of the parts. Silicone grease is used with brake parts and can be found in small tubs and in tubes. A small amount of silicone grease will provide years of service. Also good when installing radiator hoses and other tightly fitted rubber parts.

Third, assemble the clean and lubricated parts. Heat some water to just below boiling in an old pot. (You can use a new pot if the wife is not at home, but do not get caught.) Drop the bushings into the water and leave them there for about a minute. Remove one bushing, quickly wipe off most of the water, and install it into the support brace, from the rounded side, using the modified screwdriver to force the lip through the hole. Start the piece in at about a 45 degree angle, getting some of the lip already below the upper surface, then, work around the lip pushing it through the hole and securing it to the workpiece.

Almost easy when you do it this way.

Hi all
Thank's for your help.

I used a combination of rounded screwdriver & fine nosed pliers that I rounded and polished the nose end. Heated the rubbers in hot water and used lots of washing up liquid as I had no silicone grease.

I started by using the screwdriver by pushing through & then from the other side gradually pulling through.

Once you have done one it is quite a quick job.

I am sure I have answered this one in the past!

No need for sweat & tears or screwdrivers!

Wrap a length of strong flexible cord or wire round the bobbin bush, thread through the hole in the bracket and pull - like fitting a windscreen rubber!

Love it. More than one way to skin a cat and yours makes so much sense.

Does anyone have experience with the polyurethane center pin bushings - Moss part # 280-056? I don't understand how they can take the place of the rubber grommet type bushing. No matter how you install them there is play in the assembly because the bolt has a shoulder that the large flat washer bottoms out on. Either I am missing something or these are the wrong parts.

Thanks
