Burian Posted August 20, 2010 Share Posted August 20, 2010 HI has anyone seen this before? My Bedford MJ fan assy popped out whilst I was running. The impelor has come adrift from the shaft, or the shaft has broken, not determined that yet. Luckily the assy fell down and did not damage anything else. Just wondered if anyone had come across it before. I will post photo's when I get the pump off. Sorry about quality of these, not much room between engine and radiator.

julezee001 Posted August 20, 2010 Share Posted August 20, 2010 Wow! Your unlucky to have the pump fall apart, but very lucky not to damage anything else! I've never seen the whole shaft come out before. The only similar one I've dealt with was on a 110 Landrover whilst on Thetford training area. It popped it's belt off late one day, which I quickly refitted, thinking it had been caught on a branch or something and flipped off. The next day the whole fan assembly came off because the shaft had snapped in two! Again fortunately, nothing else was damaged.

Burian Posted August 21, 2010 Author Share Posted August 21, 2010 Yes should really call it The Water Pump Blues. Looks like the seal failed and over time water has got into the shaft bearings and possibly weakened the circlip. Eventually the bearings collaped and the impellor has rubbed agins the body. eventually the shaft has worked its way out. Luckily it fell over as soon as it got far enough out and the belts jumped off. So far cannot see any other damage, now ned to get the hoses replaced and a new pump in place before rust gets a grip.
