Gents:

I'm new to the list and also to owning a Ford V8. I've got some experience with Ford Straight 6's only. I've just acquired an '89 F150 XLT with the 302 and overdrive trans. The truck has 476,000 kilometres on it with 150,000 on the trans. It runs fine - no smoke from the pipe and all that's broken is a driver side power window motor.

I have a few questions for those who've done it -

Oil pressure is low on the gauge. Where do I get a mechanical pressure from, the sender? If so, where is the sender? I'm thinking if mechanical pressure is ok, it's sender and/or gauge problem. Any tests I can do?

Water Temp is low on the gauge. Where is the sender? Any way to test it and/or the gauge?

If the Oil Pressure is a real problem (let's see, 476,000 K won't wear out main bearings will it?), can I change main bearings in the truck or do I have to pull the motor? Any tricks?

Can the window motors be changed? I had a look yesterday and it's a pretty small space to work in the door. The winder mechanism is 'riveted' on with those big ugly lookin' 3 legged fasteners - drill 'em out?

Thanks in advance from someone yet to get a shop manual. (today I hope). What's the recommended manual for the new guy?

About the window, don't drill out those rivets. Thats the wrong way to do it. Instead, use Ford's method: Look for 3 dimples on the door panel metal. With window UP!, drill through dimples with a 1/2 inch bit. Use these holes to get at motor mounting screws. After putting motor back in, tape over the holes with plastic tape of your choice.
If the motor ran, but would not move window reliably, the plastic bumps on the back of the drive gear in the motor assembly probably broke. With motor out, pull screws that hold the gearcase cover on, pull out big plastic gear, clean out old grease and broken bits. Then find 3 spacers that will fill up the space between back of gear, and the metal triangular output drive. Try hardware stre for nylon or metal cylindrical spacers. Don't get them too long, want the gearcase cover to still fit tight to keep out water. Grease with the black grease, and put it back together.

 

MOLDER,
your Oil pressure sending unit is located just above where a manual fuel pump would have been, drivers side of the motor half way up about 3-4 inches in from the front, the water temp sending unit is located passenger side just behind the goose neck. low oil pressue is a sign of worn bearings, The oil pressure is read directly off of the cam bearings. However as the rod/main bearings wear less pressure is applied to the cam bearings. you can change the rod bearings without pulling the motor, athe mains will be more difficult. I would recomend pulling it and having a machine shop go over your block. good luck
