OHV engine mounts

[Bunji]

The official Triumph Dolomite Range 1976 Onwards Catalogue identifies the 1300, 1500 & 1500HL as using an engine mount having a part number 149934 and the 1850 is identified as using a different mount with a part number 158016.

However if you look at later documentation such as the Rimmers catalogue edition 2.2 it indicates that 1850/1500/1300 all use 158016.

I have also been told that at some point in the production life time, the hardness of the rubber was measured and a coloured blob of paint was used to indicate the rubbers hardness and it was then possible to select the mounts with the most suitable hardness for your engine. I can’t remember what the code was or which engine used the harder rubber mounts. This marking process was not continued in later production you were just supplied with a part 158016.

When Chris tested a number of mounts that I took down to him he was able to divide them into two groups these being either 60 or 70 shore and Chris’s assumption was that harder 70 shore would be for the heavier 1300/1500 engine. I do not think he considered the engine torque might be the determining factor so there seems to be a case to reconsider this.

Today I checked the set that I have had on one of my 1500cc Dolomites now for three years and there and there is no signs of them delaminating.

When it comes to engine movement when I attempt to move the engine by hand there is no movement and this compares with some movement with the old rubber type mounts on my other cars.

I do not know how many engine mounts he has sold and what feedback he has had.

If any fellow members have fitted them what is your assessment of them?

Hi, after reading your post I have just replaced the old engine mounts on my 1500TC with Chris Witor's 70 shore. They were easy to fit and have improved the driving experience massively. Knocks and rattles which I have struggled to locate have now gone! So very please with the result They feel pretty hard, with little engine rock, but then I am comparing them with the old mounts which were in poor condition.

Good to hear. I have a set of the same on order. Once they arrive here in NZ and are fitted (a month or so away) I will be able to report back.
