Leaking Trunnions Vitesse


Recommended Posts

Put in new Trunnions last year - one of them is leaking already - looks like shoddy manufacturing - Can I solder or araldite - Looks like the trunnion will have to come off to work on it ie remove oil etc 

 

Any assistance welcomed , also noticed the next job , the bushes that came fitted to the new front dampers have started to break up 

 

Hey ho

There was a thread about this last year, you might be able to find it. The answer is yes! I think the thread was about sealing brand new ones as a matter of course because of poor quality. Yours will have to be cleaned before you do anything, another job for the dish washer? :lol:

A trip in the dishwasher might help, but you need to get adherent Araldite (other epoxies are available) right into the joint, and any oil at all won't let it stick.

But give it a whirl (in the dishwasher) and try, a new one can wait.

Hello this topic reminded me of my same issue last year.  I bought my Herald a couple of years ago and the first job I did was to change the trunnions as I was not happy with the way the previous owner had them serviced, he even took it to a garage as he was not a spanner man.  I purchased new trunnions from a well know supplier after fitment and filling up with oil I noticed a drip from the bottom where the blanking plate is inserted.  The remedy was to give them a good clean with a good quality engine cleaner (I got away with out taking the trunnions of again and to use a product called JB weld available from good motorist shops.  The compound comes in two tubes which you mix in equal proportions.  So far so good no more leaks.

 

regards

John, I put a lot of car bits through my old dishwasher, probably the reason I have a new dishwasher!   :lol:  It was very good at degreasing car parts, although I had to act quickly when my carb pistons started to turn orange before my eyes.

 

Andrew, I think JB Weld was mentioned in last years thread, must be good stuff.

Opted for 1 penny approach plus borrowed the wife's Brulee gas gun - got to buy some more gas before she finds out ive used it 

 

I purchased the Trunnions a year ago from a reputable source at a premium price, not sure what I need to do to get products which last

 

Just testing the trunnions to make sure they dont leak again 

 

Again thanks for all the advice

My car had an MoT advisory of slight play in a trunnion last year, so it was replaced by a local reputable Triumph specialist who, on the basis that 'all the new ones leak', filled it and the vertical link with graphite grease. So now I have one oil filled and one grease filled, but I'm not using my car as a test subject to answer the age old debate :-)

Why did you bother with the penny?

It's not the metal disc in the bottom that leaks but the joint all around it.  If you are as skilled as you are at soldering, then filling that joint with lead will be an excellent repair prevention.

I installed a power shower in the bathroom and had to blank off the old shower head. A 5p coin proved ideal. Getting a bit worried now, the coin police are everywhere! :ph34r:

Hi John - I used the penny as it worked well as a heat sink , though will try filling the other direct with solder

ep 90  GL4 is recomended ,  ( could go to EP140 in a trunion)  more modern GL5 only eats bronze.brass,copper metals when in hot arduous conditions, like gearbox and especially Diffs

 

it wont affect trunions , but then if you only buy GL4  youre safe where ever you use it,,

Sorry to hi-jack the thread but which grade / make of ep90 is safe to use on the trunions? I can't find a thread showing it but I'm sure I've seen one somewhere saying the modern stuff eats the bronze?

Castrol EP90 is GL4 so safe to use
