RE: Oil pressure sender

I pulled my Jaeger sender apart after it flat-lined on the electrical tester. The housing is crimped onto the body so there is pretty much no way of separating the two without destroying it (which I did). The best way may be to cut the housing circumferentially with a Dremel cutting wheel, then soldier it all back together. When you get it apart you will find a surprisingly complex little instrument that is essentially a pushrod that comes up from a diaphragm that is attached to a potentiometer board with various resistors and things wired into the loop for the "alerte" light. Of course, as oil pressure rises, voltage through the sender increases until the unit is almost a straight ground. If you can separate the housing safely, you may be able to restore/improve the components. You might even be able to splice in the guts of a Jaeger sender from a Jaguar E-type, which are available in the local grocery store. Fortunately, Bill at GTCP had a used sender taken off a Uracco sitting in a junk pile (literally, a pile of parts) at his shop when I was there, and it has worked faithfully since. When it craps, I think I"m going to thread the fitting for a standard oil pressure line and install an Autometer gauge, or thread on an adapter and fit a Jaguar sender.

I"ll see what filippo has that i could play with. Good idea tho. ----- Original Message ----- From: Jack Riddell To: VintageLambo@yahoogroups.com Sent: Tuesday, December 03, 2002 5:06 PM Subject: Re: [VintageLambo] Parts Wanted/Needed Steve, Did you ever consider taking apart the unit? I have often wondered what contraptions they contain. Maybe they can be fixed!?

If I do have one, it was probably giving me erratic readings. Are you still interested? Nope, I got one of those! Thanks anyways. stevo Jack I think the wanted/for sale list is a good idea - Fred, what do you think? Steve wrote: I have a 73 Espada and am in need of a Oil Sending unit. This part was identical on all years and series. Anyone have a working used one on a shelf somewhere?GT Parts, etc. don"t carry them anymore. And on that note, should we create a new folder/area for a wanted or for sale list? Thanks, stevo
