Tach successfully removed. Picture of removed tach hopefully will post correctly. The short story is the silver "can" in the first photo is the housing for the tach and it simply was both rusted in place and held in place by an ancient decaying rubber gasket. With a little wiggling it did push through the front of the instrument panel. Now it is off to the repair shop.

Ok, thanks for clarifying the differences between the two vehicles regarding type of tachs, mechanical vs. electric, but what I was really after was how to dismount the electric tach from the instrument panel. I wasn't clear that I don't think the tachs are the same, I was asking if their mounting systems were the same. But perhaps not. Your point about the rubber gasket between the bezel and the face of the instrument panel is helpful and I'll do some very gentle prying around the circumference of the bezel. The tach tracks increasing RPM correctly, but upon deceleration/reducing RPMs, the needle sticks and requires a slight tap on the glass for it to drop to the correct position. In talking with the instrument rebuilder, they agree it isn't likely a problem with the electronics, but rather a dirty or worn mechanism so the fix shouldn't be too difficult....for them. Thanks.

As shown in the attached photo, there is a leak somewhere in the inboard portion of the driver's side front drive axle on my Fox. I haven't pulled the flexible boot off yet but will have to address this problem soon. Does anyone have any information such as an exploded diagram of the internals or better still, a source for any of the seals and gaskets that may have to be replaced? I understand that the wheel, brake assembly, and gear drive will have to be removed to access this area. Does the drive axle also have to be removed or any of the other suspension pieces? Thank you.

I need to remove the tachometer in my Fox armored car for cleaning and calibration since the needle is sticking. I've pulled the instrument panel and removed what I thought were the two retaining clips on the back of the tachometer housing but I cannot get the tach to come forward through the panel. The mounting system appear similar to that of many other 1960's and 1970's vehicles I've worked on. I've attached a photo showing the rear of the instrument panel. The silver looking "can" is the tach housing and note the two silver threaded rods which have already had the nuts and retaining clips removed. While not shown in the photo, I have removed all of the screws on the back of the tach housing and they are not the cause of the mechanism not coming out of the housing. I suspect the tach on a Ferret is similar, has anyone any suggestions on how to remove?

Jon, Thanks for the tip. I'm on the trail of a malfunctioning temperture gauge and was thinking it was going to be eaiser to test the gauge before crawling thru the wiring all the way back to the engine. If I get the panel out sucessfully, I'll post a picture here so others who have to deal with this have an idea how to do it.

So there is no removing it without disconnecting the line?

Any Fox owners who have successfully removed the right hand instrument panel WITHOUT disconnecting the hydraulic line to the steering box? What is the trick to this or is disconnecting the line the only way to do it? With all panel screws removed the lower edge of the panel tilts out easy enough but not the top edge as the depth of the gauges/switches don't allow the top edge to slide downward any to clear the steering hydraulic line. Thanks for any practical suggestions from those who have accomplished this.

Here is my first step in creating a male mold to vacuum form this piece out of .250 thick Plexiglas G. Of course on top of this initial plywood cover I'm building out the rectangular portion which houses the bullet resistent glass. Will post a photo of that once I'm done. If anyone who has ready access to an orginal could measure the extent of the protrusion of the plastic which houses the actual bullet resistent glass that would be most helpful.

Thanks for posting the great pictures and any others, particularly the windscreen wiper motor mounting, the flange area where the screen contacts the hull and internal mounting for the windscreen would be helpful.

Pictures would be great as would a measurement of how far the projection molded into the windscreen protrudes forward from the hull. As you have a couple of them, would you be willing to sell one? Thanks for your reply.

With enough money thrown at a project you can make anything. Now it may cost more than the vehicle itself but that is another matter. Actually we have started on a male mold and can have the final product blow molded. What I was hoping for was better pictures and some dimensions of the portion that protrudes forward to allow the driver to lean forward enough to see what traffic is approaching from the sides. A single piece of glass wouldn't work as the hull at the opening is angled at the hatch requiring at least two pieces or as many as four if not using a blow molded acrylic. But thanks for the input.

For road inspection purposes I have to fabricate a windscreen for my FV721 Fox. I've only located one photo of the Approach March Windscreen for this vehicle and I have the one drawing of it from the Parts manual. Does anyone have any other photos or drawings of this windscreen? Or any advice if you have built your own? I've given up on trying to locate an original though I expect five minutes after finishing mine, one will be listed on EBay!

My thanks for such an informative thread. As the new owner of a Fox and living in the very southern U.S. cooling is always a concern. Lacking access here in the States to the wealth of experience available from those that worked on these vehicles while they were in service I'd like to raise the question of what, if anything, could be or was done to improve the cooling situation beyond block modifications? Either operational changes in they way they were operated or other modifications to the vehicles while in service?

Greetings from the southern U.S. I'm Wade. I joined this forum having just now discovered it. I'm a lawyer, firearms instructor and indoor firing range owner and also a retired U.S. Air Force Electronic Warfare technician. I started restoring older cars years ago (that's a nice way of saying that's all I was able to drive at the time) and my interests have expanded to military vehicles. I currently own a 1971 M35A3 (2 1/2 ton truck), a 1962 M37 (1 ton truck), several trailers and my newest addition, a 1976 FV721 Fox. I'm looking forward to learning more about the British military vehicles as well as sources for spares for the Fox.
