Be3 Box. Crb Failed Now Twice In 500 Miles

Recommended Posts

Not mine so I'm going to struggle with all the details.

Road rally 1900 8v. Fitted with std clutch and BE3 box. twice now the release bearing has failed. I haven't seen the box off so can't say if everything is ok in that deptartment. the last time it failed the genuine Pug bearing seemed to slip around say 90 deg off the forks basically and made a nice nick in the little post (name? - it's early!) the bearing sits on. The bearing did seize or breakup. Should there be any clip to hold a BE3 bearing on the fork, other than the little plastic 'barbs' on the bearing itself?

I don't believe there is anything radical with the clutch/ flywheel. So I don't think there's anything a miss. The clutch pedal (it's all back together when i saw it) feels ok, not heavy.

 

I'm not familiar with BE3 boxes (tho it seems I have two lying around!). Any common problems? All help appreciated!

ps this is form the owner of the car-

"The box is back in now with the helix bearing, i'm pretty sure (although not 100%) that you can't get them wrong , in as much as mixed up. the car originaly has the standard 1.9 be1 box, until we put this 4.4 be3 in, the old bearing did not fit so we had to buy and fit the be3 type, which is when the problem started,we did a few miles before the bearing fell off the forks, so we bought another one and did 200 odd miles and 2/3rds of the moonbeam then the same thing again, you can see why we are not convinced as we have not actually fixed anything, the pedal adjustment is the last clutching at straws conjecture. we thought the forks may have been worn but they did not appear to be,worn mainshaft bearing was another idea but that seems ok"

I had a problem with this on my BE1 where the lugs were rounded over and not catching in the fork mechanism. In teh end I put a self tapper into the plastic to physically hold the bearing onto the fork - havent had a problem since

its only the plastic lugs that hold it onto the forks, they fall off quite easily if the clutch arm is knocked during installation though and will sit at 90 degrees to the forks as described.

 

things to check; clutch shaft forks are straight, clutch fork bushes, that's pretty much it!

The Bearing supplied by Helix is a OE bearing anyway so thats not a issue, As said check the fork from the shaft as these wear and can allow the bearing to pop off

I remember I always made sure not to pull/catch the clutch arm too far whilst fitting the gearbox as this can unsettle the bearing off the fork. I always thought that was a bad design but once the gearbox is on it shouldn't ever come off I'd have thought. Does your gearbox have the inspection window at the front? Think my casing has a fair size hole at the front with a plastic/rubber cover that can be removed.

yes, problem is you can only see through it if you take the radiator out or the engine and box out!.

Not sure as it's not my car and I'm not familiar with it. The electric PAS is in front of the box so that would cause problems too. Might be possible to use a mirror I suppose.

 

Thanksfor all the replies. I think they're just going to have to try it and see. Maybe it is the clutch ofrk that is worn

A friend's BE3 205 destroyed its release bearing and chewed up the fingers on the diaphragm spring. It turned out to be because the plastic bushes in which the release arm's cross shaft rotates were fitted the wrong way round, so the release bearing wasn't concentric with the input shaft. Might be worth a look.
