OHV engine mounts

[Bunji]

Has anyone tried the Superflex stainless & poly engine mounts (replaced OEM# 158016), and if so what are your thoughts?

[yorkshire_spam]

I have their poly mounts on my 1850 - happy with them so far. Only been on just over 12 months though.
When it comes to suspensions bushes for Triumphs Superflex are pretty much the only ones I trust. (On Land Rover's it's SuperPro for me!)

Confused now, do you mean OHV or OHC? 1850 is OHC and those mounts based on p/n are suitable for the 1850.

Ahhh same p/n for 1850 and 1300/1500!

I fitted some to my 1500HL a few years ago now and am perfectly happy with them. There is possibly a bit more vibration into the car noticeable at start up, but otherwise they are fine and far better than the modern equivalents which really don't last long at all!

Just fitted a set to my car a fortnight ago, fitted perfectly, unlike the usual repo ones. Unfortunately the poly seems to be coming away from the stainless on one of them (you can see daylight through the gap!) So I'm going to have to chase them up about it. I imagine it's a defective part as I've not heard of anybody else having issues...

Actually appears Toledo engine mount part# is 149934, which SuperFlex offers also.

I was aware that Chris Witor had started to produce sprint engine mounts so I contacted him to see if he would produce mounts for 1500 dolomites. He did agree to do this and I supplied him with a number of mounts so that he could measure the shore ratings and also measure the off set. The outcome is he now produces 70 shore mounts for 1300/1500 and 60 shore for 1850 engines which is hardness that the cars were originally fitted with due to the difference in engine weights.

I have had a set on one of my cars for a couple of years now. I have not checked them recently so I will have a look tomorrow and report back if there is any delamination. The rubber based mounts that were available just did not last.

I had a look at the superpro web site and could not see any engine mounts being sold.

Here is the link to the 1300/1500 mounts https://www.chriswitor.com/proddetail.php?prod=149934P

Will contact him to confirm the shore rating.

Also just checking, why are 1300/1500 mounts a higher shore than 1850?

[Richard the old one]

I believe it is because the engine weights are different.

That is interesting, because I had failed to remember that I too had this problem with my O/S mount. I returned it to Chris Wittor and he promptly sent a replacement - which has been fine since.
However, I wasn't sure if I had A) fitted it the correct way up and B) you could also see that when the mount is fixed to the subframe, it wasn't parallel with the mounting point on the engine, so the mount was being pulled slightly at the front edge to compensate (if that makes any sense?)

The solution (and I sent pics to Chris) was to put a small washer underneath the engine mount to straighten it up and this seems to have done the trick.

I think a combination of the above was why mine failed, not poor quality or manufacture, more poor installation on my behalf.

I believe it is because the engine weights are different.

Weight probably IS a factor, but it's probably more to do with torque output and reaction, the slant engine is much torquier (is that a word?) than the OHV so the turning or torque reaction moment will be considerably higher on the slant motor and the mounts need to compensate for this.

...but the lower the number, the softer the material...your premise would have the 1850 harder shore than the 1500

[Richard the old one]

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.
