Gromit Posted June 18, 2008 Share Posted June 18, 2008 Well I thought all the vibration was the wear in the swivel pin. After rebuilding the swivel, it seems not. I've got some knocking vibration, at prop speed, most noticeable on overrun. I can feel it in the cab. I thought it was the front prop, but having removed it, it's still there. With a front wheel on a jack (prop back on) and spinning in reverse the knocking seems to be coming from the front output bearing on the transfer box, though it's hard to pinpoint. Listening with a screwdriver the noise is difficult to locate but seems to be more from the main box. With a rear wheel spinning on a jack there's no noise, so I reckon it's the front part of the transfer box. Just changed the oil in the box and there's no change. So, could the front bearing fail in this way, giving lots of vibration? What else is there in the T-box that could give these symptoms? I guess I'll pull it and see. Where do you get replacements? I didn't see any mention on Ashcrofts. Cheers all for your help. Another LR saga week. Work are never going to see me again at this rate Quote Link to comment Share on other sites More sharing options...
lrfarmer Posted June 18, 2008 Share Posted June 18, 2008 your problem sound very much like my transfer box, mine is the front bearing. i'm putting a new one on, but you could get a new bearing. Quote Link to comment Share on other sites More sharing options...
western Posted June 18, 2008 Share Posted June 18, 2008 IIRC the front bearing 'how to change it' is in the Tech Archive in Les H's list Quote Link to comment Share on other sites More sharing options...
BLACK CAB Posted June 18, 2008 Share Posted June 18, 2008 I replace the front bearing on mine a few weeks ago. Gus (member on here) helped me out with the bearing no. 6207 LR Pt No.STC1130. I used SKF, make sure its a C3 clearance, you don't need to pay £30 +vat...... I got mine from BSL for about £12. Any way its a really straight forward job, only tools required are a good 3 leg 8" puller, circlip pliers (internal) and suitable drifts to install. You will also require a flange seal FRC7043 and maybe the circlip 216962. Just over £20 the lot. Search and you will find Gus's sequenced photos. Rod Edited to say the outer race of mine was pitted in several places, once washed out and spun it was rough, the reduction in noise is quite noticeable.

Gromit Posted June 21, 2008 Author Share Posted June 21, 2008 Thanks all for the info. I've pulled the bearing. With it cleaned up and on the bench, there's a tiny amount of roughness in it, so we'll see if it really is the cause of all the noise New bits ordered from Ashcrofts, cheap too Should have them in a few days. Will report back when it's back together. Quote Link to comment Share on other sites More sharing options...
