Area Representative Piers300 Posted September 13 Area Representative Share Posted September 13 My alternator drive belt (31213) has delaminated and has a whip like section coming away from the belt causing a speed related clack clack clack noise. Luckily, last night I realised all was not well, so the 7 was not used to attend the monthly club meeting. I need to have a good look to make sure that no damage has been done to the pipe work by the rather long piece of delaminated belt. So this morning, I got under the car in my pit to find that two hoses pass through the centre of the belt when installed. This means that something has to be undone, so the pipes/hoses can pass through the centre of the belt, when the new one is fitted. Is there an easy way to do this and what should be undone/disconnected. Piers Link to comment Share on other sites More sharing options...
Wrightpayne Posted September 13 Share Posted September 13 Just undo the jubilee clips holding the apollo tank and you should be able to thread it over. Link to comment Share on other sites More sharing options...
Area Representative Paul Richards Posted September 13 Area Representative Share Posted September 13 Cut the old belt to remove. To fit the new belt remove the braided hose from the top of the Apollo tank and disconnect the wire from the temperature sender on the side of the tank. Then remove the jubilee clip which secures the Apollo and you should be able to thread the new belt over the Apollo and into place. Be careful handling Apollo as they are thin metal and easy to crack. Refit braided hose and wire to sender and secure Apollo again with jubilee clip. To fit belt slacken long bolt on top of alternator and the bolt attaching stay. There is a tensioning screw which you will need to loosen (I think it is 8mm but not sure). It is tricky to get at. Once belt is in place over the pulleys tighten tensioning screw and retighten the bolts on the alternator. 1 Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted September 13 Leadership Team Share Posted September 13 Plus it’s well worth having a spare belt installed at the same time but cable tied away from everything important. This way you’ll have a spare that you can easily fit if you have a belt issue away from home. Stu. 1 Link to comment Share on other sites More sharing options...
Area Representative Piers300 Posted September 13 Author Area Representative Share Posted September 13 Thank you Paul and Stuart. - very helpful. The belt has been ordered from Redline, so I will have a crack at it next week. Piers Link to comment Share on other sites More sharing options...
Area Representative Nick Chan Posted September 13 Area Representative Share Posted September 13 As Ian says, you can thread the belt under the bottom Apollo tank without disturbing any fittings but Paul's method works fine too! The comment from Stu is a good idea to have the spare belt ready to fit ie. already over the Apollo tank pipes and secured out of the way 1 Link to comment Share on other sites More sharing options...

anthony1956 Posted September 13 Share Posted September 13 and when fitted check your belt is not sawing its way through an oil hose.. Link to comment Share on other sites More sharing options...
Nick Berry Posted September 16 Share Posted September 16 When I changed the belt (and added the spare), I didn't need to disconnect either pipe, just unmount the tank and do quite a bit of wiggling and swearing. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted September 17 Leadership Team Share Posted September 17 Maybe I’m missing something, but my recollection is it’s physically impossible to fit a new belt without disconnecting either the two main hoses, or the top braided hose? Maybe unless you’re Paul Daniels! Stu. Link to comment Share on other sites More sharing options...
Nick Berry Posted September 17 Share Posted September 17 I can't explain how I did it (like explaining how to tie shoe laces) I'm afraid. All I know is the new belt is on and no oil was involved. I'd just done an oil change and noticed the belt could do with changing. That led me to have a go without disconnecting the hoses. I'm no Mr. MAG 1 C.

Leadership Team SLR No.77 Posted September 17 Leadership Team Share Posted September 17 Did you by chance remove the hose take-off on the filter head when you changed the oil filter? Link to comment Share on other sites More sharing options...
Nick Berry Posted September 18 Share Posted September 18 I didn't disconnect either hose from the take off plate, no. The only thing l can think of is that I've got different hose routes (although I can't see how). Link to comment Share on other sites More sharing options...
John Vine Posted September 18 Share Posted September 18 It's a bit like one of those Xmas cracker puzzles... Green and blue are hoses and red is a continuous loop. How do you move the loop from A to B without detaching either the green hose or both blue hoses? JV Link to comment Share on other sites More sharing options...
Nick Berry Posted September 18 Share Posted September 18 So, looks like I must have disconnected the breather but don't remember doing that! Link to comment Share on other sites More sharing options...

SM25T Posted September 18 Share Posted September 18 Breather hose is an easy and safe disconnection compared to the oil hoses. Link to comment Share on other sites More sharing options...

Right, I’m changing the water pump on my supersport and had to remove the belt. If the Apollo tank loosened from the chassis, you can slide the belt under the tank, over the two large hoses (bit of a force required) and then up to the top of the tank. The top breather pipe does need to be undone but that’s nothing compared to undoing the big pipes! Two new belts ordered and ready to go back on 😀 Link to comment Share on other sites More sharing options...
