Brucey Posted September 15, 2005 Share Posted September 15, 2005 I've just changed my alternator belt. I tried to get the same one I took off 40750 (which I assume is 4 grooves, 750mm long). Halfords said the correct belt is a 073704 (4 grooves,737mm long?)as the alternator used to get close to the side with the old belt, I bought and fitted the slightly shorter one. This was a bit of a squeeze to get on and when adjusted is VERY close to the terminal on the oil pressure sender unit (on top of the oil filter housing). In fact I think I've damaged terminal when fitting the belt as the oil pressure gauge was doing impressions of a geiger counter, but is ok with a bit of 2 mm rubber wedged between the alternator body and the terminal ☹️ I was a bit concerned as I was running the engine with the car jacked up (I did check the oil level first ) to bleed my new (second hand) ally rad. This combined with a new 82 deg stat seems to have improved the temperature problems, (sits at 85 deg now) although I haven't actually tried it with 4 wheels on the ground yet! 😬 Is it just me that manages to generate more work every time I do something? 2 questions. a) Which belt is correct? or is there an 'in between' size. b) Which oil pressure sender do I need (Rover item from a motor factors or Caterham job)? I guess I'll have to take off the alternator and drain the oil to change the sender 🙆🏻 Thanks in advance for any advise. Link to comment Share on other sites More sharing options...
Dartmoor7 Posted September 16, 2005 Share Posted September 16, 2005 Caterham parts list shows GFB80743 for the 1400, GMB50735 1600 from 1996. I always get bits from CC, rarely more expensive, don't have to go looking, arrives within two days. Jerry Parker L7 SVN 1400 Supersport Link to comment Share on other sites More sharing options...
Nifty Posted September 16, 2005 Share Posted September 16, 2005 I used a shorter belt on my alternator too for the same reason Bruce. I had a Gates belt fitted. Unfortunately I've changed to a Brise alternator and a different sized pulley so can't give you the appropriate Gates belt number.

Mick Day Posted September 16, 2005 Share Posted September 16, 2005 Sorry to hi-jack this thread but this is a question or 2 for Nifty: 1. Which Brise alternator did you get? 2. Did it need new brackets & if so did Brise supply? 3. Any problems or any advice on fitting? Many thanks in advance & sorry to hi-jack.

Nifty Posted September 16, 2005 Share Posted September 16, 2005 Mick, Sorry but I can't remember which alternator it was, if I can find out I'll let you know. I specified it with a smaller pulley in order to get it further away from the chassis leg. I did have to change the alternator hangging bracket on the block from the earlier type that takes two bolts to the later type that takes one through bolt. Fortunately I had a friend withna spare block with the right bracket on it so I just nicked this. Best bet is to give Tim Brise a ring. Nifty.

Mick Day Posted September 16, 2005 Share Posted September 16, 2005 Thanks Nifty, I'll pop down to Dartford & have a chat with Tim. I need to get a couple of starter motors repaired so the alternator can go on the list for the winter rebuild project. Mick Link to comment Share on other sites More sharing options...
Brucey Posted September 16, 2005 Author Share Posted September 16, 2005 Thanks Jerry & Nifty. No problem Mick, you can hi-jack my thread any time. Its nice to know I'm not the only one with problems! Using my previous therory, a GFB80743 should be 743mm long which sounds about right to me I twiddled the terminal on the oil pressure sender and it seems to be working o.k now I'll have to remember to cut the old alternator belt off when I fit the slightly longer Caterham one so I don't hit the terminal again! Thanks again guys, I'm a bit happier now 😬 Bruce. Link to comment Share on other sites More sharing options...
Dartmoor7 Posted September 17, 2005 Share Posted September 17, 2005 If you buy a used car, never assume the previous owner fitted the correct parts, always check instead of just replacing with the same. There are a lot of 'upgraded' 7s out there. Jerry Parker L7 SVN 1400 Supersport Link to comment Share on other sites More sharing options...

Nifty Posted September 17, 2005 Share Posted September 17, 2005 Should we have a 1400 SS fringe club ? 😬 😬 😬 😬 (Mind you if plans work out I'll be joining the 1800 club shortly *thumbup*) Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
