gents please assist

Attached look at pics of two mountings removed from Mufetta 1982 240GD now with a 300GD.

The left mounting is the higher one and obviously newer without a spacer. The right hand mounting is lower / thinner by about 10mm and with a spacer.

Questions: According to MBSA the one side is only round and left - # 5 on drawing - right?

According to MBSA the wedge shape mounting # 8 is available in left and right - but the brackets in all 240' / 300's ive seen will not fit. Right or wrong?

What is the pupose of spacer #20?

Is the mounting #5 for left and right side the same or do they differ?

:roll:

As per my post on Roons' thread, at some stage MB changed the 300 GD left hand mount to a trapezoidal one. Before that both were round.

I have mailed you the correct Vin of a 2 round mount GD 300.

You photos made me scratch my head from the back to the front. I was unaware of the different heights.

Round both sides or square both sides. Mbsa parts guy idiot - does not know how to use epc. Left and right on a 300 have different part nos relating to different shore hardness and possibly height diferences. Ring possibly just a retainer could possible be done away with but i guess there must have been s reason for it

Thanks gent

I gave the parts dept 5 different 460 vin no's and the outcomme was the same.

Round mounting just for the left side and just 1 part no available.

Wedge shape mountings left and right.

I am even more confused now!

Think you will be able to see on fan/radiator shroud if you need that spacer by looking at space between fan and shroud. Will be difficult to see any difference on angle at the rear with such little lift.

I think Andrew has mentioned the engine support brackets for square mounts and round are different. Think initially these were iron brackets and changed to same shape in aluminium at some point.

Perhaps the other way round.

Also when they changed to the one square mount as per the epc print above, the carrier in the chassis also changed, ie there is no solution to use SY mounts on an old round mount G without cutting and welding on the chassis.
