K Series Rubber Engine Mounts


Guest

Recommended Posts

Hello Guys

 

I need to replace the engine mount rubbers on my 1996 K Series. The Caterham part number is BM 382FS and availability is not a problem, can anyone advise if these mounts are specific to Caterham if not where should I start looking.

 

Thanks

My car came with the Caterham ones, which my Duratec ripped through the RHS one in about 5K miles. LHS one fine. I bought some aftermarket ones labelled as being for Jaguar XKE, and again the one on RHS was ripped through about 5K miles later. LHS one still fine. I installed another XKE one, but with a B.F.W. (big washer - the "f" is silent) on the top of the rubber to simulate the effect of the Vibra-Technics design, and they are both fine with another 7-8K since the last change.

Any ideas why they should fail so quickly in your car?

Uprated ones are now also available from vibra technics - not sure if anyone has reviewed them though...

A few of us have been running these for a while. I think Paul Deslandes' car was used for some of the dev work. I've had both their engine and gearbox mounts on my track car for a few thousand track miles over the past couple of years with no issues. AVES did have a problem with the centre bolt/nut in his VX-engined 7, although I can't remember if this was resolved or not. He mentioned it somewhere in Chit Chat.

 

About to fit a dog bone mount modified with Vibra-Technics bits to my Skoda over the next few days.

 

I could look into an L7C group buy type thingy if there is enough interest? Maybe even a factory visit too. They have a set of car ramps and (to a simpleton like me) some awesome machinery and test rigs to make and measure mounts and bushes.

Hi Guys

 

I have ordered Jag Units and will see how they last. They look identical to the CC units but at £17.5 a pair all in it must be worth a try.

 

Cheers for all the info.

Torque? Combined with maybe an overly sharp lower edge on the tube the large bolt passes through in the steel bracket?

I do find it curious that it is only the RHS one being torn, which is why I mention torque, but the BFW seems to have corrected the issue.

@BBL - For the record, can you recall the size of the BFW you used? I'm guessing some kind of thick ½" penny washer?

No - it was over 7,000 miles ago! - but I chose it by taking the large mounting bolt with me to the hardware store and looked for what is known here as a "fender washer"; the biggest O.D. steel one I could find with an I.D. that would fit the bolt. The purpose is to spread the load from the downward force of the RHS steel engine mount bracket across a greater surface area of the rubber engine mount.

 

I may be able to measure the O.D. of it without removing it, but I am just having lunch now in California. *wavey*

(Should have driven the 7 to work today and I could measure it right now, but I didn't wake up early enough to beat rush hour, so took the tin-top instead)

 

 

edit -- I used this engine mount manufactured by URO, which seems to be the common one available. They were $5 USD when I bought them, but have since gone way up in price! *smile*
