Car Forum / Mitsubishi Cars / August 2007Chariot - How to remove the alternatur/vacuum pump ?
Dear All, Last weekend I had a total alternator and break failure, which I put down to either of the two components failing, probably a baering failure in the alternator or the vac pump. I have tried very hard to remove the alternator and removed the two main nuts and bolts, but all the other pipes suurounding the assemly making it very difficult to see what needs doing. Has anybody ever done this before, and as a quick suggestions what needs doing ? Many thanks, your help is much appreciated. Kind regards Al: > Dear All, > > Last weekend I had a total alternator and brake failure... > I have tried very hard to remove the alternator and removed the two > main nuts and bolts There's the one main pivot bolt (about 120mm long) down near the block. There's the adjuster/tensioner bolt and lock bolt on the top of the alternator. You don't have to loosen the power steering pump, but it may make removing the alternator easier. Once the the above bolts are removed and you've disconnected the belt, the alternator just pulls off and drops down. Try not to damage the radiator as you do it. > ...alternator and brake failure These are usually not connected. Alternators do fail, usually its the internal diodes, but bearings can also wear out. Get a rebuilt unit. Vacuum pump? What year/model of Chariot? Do you in fact mean the power steering pump that sits above the alternator? What was the nature of the brake failure? The pedal got very hard, or did it hit the floor? More info please...

My Mitsubishi "Chariot" Diesel was originallly build in Japan in 1994 and is fitted with a alternator which has a vacuum pump attached, very similar to the image on the link given http://www.lucas-tvs.com/products/3ha.html Yes, what happend was as follows : The charging warning lights came on half way during the trip, and the break warning lights came on at the same time. Initially I was unable to understand the problem, but having spoken to a local Mitsubishi garage I was assured that the vacuum pump was indeed piggybacked on the back of the alternator. What I have been able to do so far was : A) remove the tensioner lock bolt B) remove a nut from the pivot bolt ? But the lovely thing will still not move, hence the belt can not be taken off. Have a nice evening.

OK, I thought it might be a diesel. In any case, all you have is an alternator failure that causes some or all of the idiot lights to turn on as you report. My 93 Eagle Summit Wagon (in effect a Chariot RVR) does this when the alternator has a problem. You don't have a brake problem at all. On the pic link, the 120mm pivot bolt is the one you see at the bottom with the two insertion points. The tensioner lock bolt (approx 25mm) is the one at the top. Remove the pivot bolt nut, and the tensioner lock bolt. You may need to get a lever (a length of 2x4 is often handy) to detension the belt. You can usually wedge the 2x4 on the road and against the alternator. You'll have to remove the hoses from the vacuum pump too. Once the belt is off, you can remove the pivot bolt.

Upon inspection I had noted that the drive belt used by a previous installation has been totally the wrong type, too small in width and too short, I could only remove the belt by cutting it with a saw , that short. I will on monday have the alternator tested and overhauled by a local specialist . Perhaps you would be good enough and give me some guidance as to the follwowing questions . a) How can I most easily remove/ and replace the belt from the engine to the Oil pump ? Do you happen to have a Mitsu part number ? Or do you have a dimension of it ? b) What is the Mitsu part number for the belt I have just cut, or do you have a dimension of it ? Great website my friend, enjoy your hobby in earnest. So have a nice weekend Kind regards Al: ---- I'd like to help at this level, but I don't have direct knowledge of the diesel models. > a) How can I most easily remove/ and replace the belt from the engine > to the Oil pump ? Do you mean the cam shaft belt? > b) What is the Mitsu part number for the belt I have just cut Can't help with a Mitsu number, but its easy to measure. Locate the alternator at the 1/2 adjust point, and measure the belt length over the pulleys with a piece of string. My 93 gas engine model has a 4 point micro-V belt, 14mm wide x about 800mm (it's a Gates 040390). Most parts places have a cross reference for length.
