dch1950 37 1 Cars Posted July 23, 2009 Hi all, glad to have got the matter of the crossmember seal sorted. Although I think any gap at that point will let water and dust into the beam. Still.... Next problem. The beam I am working on was in reasonable nick so a good clean, replace front mounts etc and we're looking good. I have cleaned up the arms and shafts prior to re-assembly. Then got diverted by the Xmember seal business. I finally got to dry fit the arms (by that I mean not all greased up) to check things. Bugger me I drop each arm in in turn and each one sits about 3mm clear of the tube housing. I then measure the depth fit of the inner bearings and it's 19.9mm each side.- Hmm. I then measure the shafts and find that they need to set at 21cms to put the inner race in the middle of the machined section of the shaft. My 3mm gap is caused by a lip machined on the shaft and I need to drive the inner bearing by about 6mm. Thinkinkg about setting gaps etc I can see that It wouldn't be possible to set the xmember seal properly as the arm would always sitting proud of the tube - Damn. So the problem is what can I use to drive the inner bearing in a bit more? My shafts are OK so I didn't have the opprtunity of getting/using an old shaft (turned round) as a drift. Any suggestions guys regards Dave Share this post Link to post Share on other sites
pug_ham 245 3 Cars Posted July 23, 2009 You could use a socket that is close to the same external diameter of the inner bearing / tube which fits through the outer bearings & seal. Thats how I used to fit the inner bearimngs before I got an old radius arm shaft. They shouldn't need much force to move them in but what car are your shafts from? The book figure is 20cm into the beam without the seal or carrier fitted. Graham. Share this post Link to post Share on other sites
jimistdt 1 Posted July 23, 2009 How about a 1/2" drive socket and extension and a rubber mallet, is that long enough? Share this post Link to post Share on other sites

The book figure is 20cm into the beam without the seal or carrier fitted. Graham. I bought the beam as a 1.6 one. I assume that the arms/shafts are the right ones. here's a piccy. At 19.9mm I'm hitting that machining transition. Shafts seem to measure up OK though (for the bearings at least) I'd thought about a socket and extension but the biggest I have is 1.25" AF which is 42.5mm diameter. It goes through the outer bearing OK but I think it needs to be a bit bigger (i.e about 47mm) regards Dave Share this post Link to post Share on other sites
Daz_C 8 1 Cars Posted July 23, 2009 I use a hub nut socket and an extension bar. Can't recall what size it is off me head but the size for 1.9 hub nuts if thats of help. Share this post Link to post Share on other sites
dch1950 37 1 Cars Posted July 24, 2009 Hi all, thanx for your input - much appreciated. I've been scratting around in old tool boxes and have found a old 3/4 whit socket which measures at 44mm diameter. This only 2mm bigger than the ID of the inner bearing (42mm) though and I'm thinking it might damage it. Would a 3/4 drive socket be better? I haven't got any mind you so perhaps this is a bit wishful? Dave Share this post Link to post Share on other sites
dch1950 37 1 Cars Posted July 26, 2009 Hi all, This is a quick postcript to the inner bearing problem I had. I didn't see that poor re-assembly was the problem with my beam when I stripped it down - I was looking for the inevitable wear on arms etc. However I met up with Ryan (forum member) yesterday and he kindly gifted me a used arm shaft. He also gave a little shaped plate/washer which would drop into the inner bearing. Thanx again mate. Saturday pm tried the shaft in my beam. It wouldn't fit even after wire brushing and a touch with a grind stone. Not good. The problem - of course was that I wasn't doing things in the natural order. Remove old bearings, fit new inners, finally fit new outers. I then used the little washer/plate and the shaft inserted narrow end first. A few taps with my trusty copper head mallet and job done! Thank god as the alternative was to scrap 2 perfectly good outer bearings (1 brand new), reset the inners and buy 2 more outers to fit. So all in all a good result. Moral of the story is check,measure,check again etc,etc you get the idea. Dave PPS Ryans PH2 MI16 is a bit tasty - certainly compared to my 1.6 rather tatty standard model.
