MG MGB GT V8 Factory Originals Technical - An easy question on motor mounts
I have just recieved a shipping of v8 goodies. When studying the alloy reproduction of the v8 motormount its not clear in what sequence one should assemble them. Having hoisted my trusty 4banger and changing the round rubber motor mount on the steering wheel side some years ago. I can still remember how hard it was to fasten it behind the steering shaft.
This is why I call on you. Should I fit the mounting rubbers to the frame leg and the inserting the small bolts to the alloy motor mount. It seems tricky to align. Which is the best way or possible way? The second question. Which way should the rubber mount be fitted. There are two possible ways, one high and one low position. Which one is right?
By the way, the car is a 1979 rubber bumper left- swinger.
|Erik, remove the steering shaft.Bolt the rubber mounts to the alloy ones then bolt the assembled mounts to the engine block. Lower the engine, aligning the engine mount studs with the slots in the chassis rail mounts & tighten the fixing nuts before you replace the steering shaft. The alloy mounts may be left & right handed, depends on who made them. Also , don't forget the earth/ground strap.You may also need a spacer or two between a rubber mount & the chassis mount. The backing plates off old rubber engine mounts make good ones. Good luck .Barrie E|
You can loosly attache the rubber mounts to the brackets on the car rail, ie start the nut on the rubber mounts. Then lower the engine into place and then attache the rubber mounts to the engine brackets, which is how I did it. My (home made) Brackets had captive nuts which made it easy. Or some variation. I should say RELATIVELY easy. I found the exhaust made acess to the steering universal joint difficult.
Or do this with just the steering side.
Now to the second question. Since the bolt on the rubber mount isŽnt centered there must be a reason. I guess the constructors had something in mind while taking this route. Should I assemble the motor mount in the "high" or in the "low" position?
By the way. Oz is a great place. Had lots of fun there in the late seventies when working for the Pacific Australia Direct Line, PAD.
Ask Clive Weathley. IŽll explain you in which way they should be mounted. You also found the information in the Workshop Muanual for MGBGT V8.
Sorry I forgot in which way I have done that last year.
Ich will Clive fragen. Du ist richtig. Ich hat meine sachen von Clive gekauft.
All the best
|Bolt in the up position otherwise the rubber mount doesn't slide down as far as it should and butt up against the ledge at the bottom of the body/rail bracket. Trial fit it and you'll see strait away.|
Thank you, this bit seems clear. While IŽm at it I might aswell ask. At present there is two shims on either side of the 1800 engine mounts. A lot of people discuss the need of more space on the steering side. In my case the left side. Is it smart to remove the two shims on the opposit side ie starter motor side und thus creating more space between the steering rod and exhaust?
|EDrik, the shims are normally only fitted on the steering side to create more clearance for the steering shaft.They are fitted "as required".If you don't have a clearance problem , then don't fit them.You won't really know until you trial fit the engine. hang the headers on also before you make a final decision.
