Volvo penta 740 lower unit will not go down.

I have a 1991 regal with the volvo penta 740DP. The lower unit will go up but not down. I have replaced the tilt motor, all three sylinoids(even the trailer switch under the dash), redone the wiring, and re-ran the ground cable. I have drained and replaced fluid several times as well. I am stuck. Any one had this problem.

Kind of sounds like the trailer switch is in control. Many of these switches have lockouts and if you move the outdrive past the trip point the other solenoids are dead. Watch fingers. There may be a tilt switch on the water side of the transom in the pivot housing.

1991 Volvo 740 shuts off i replaced the fuel filter and still it shuts off any suggestions?

Have a fuel pressure test run. Your car is 20 years old and if the fuel pump has never been replaced that is more than likely your problem.

Timing for a 1991 volvo 740

Hi, this is how to align timing on a 1991 Volvo 740.
There are marks for all three. Cam and Aux shafts have dots on face of outer gear. Cam lines up with mark on rear timing cover(about 1 o'clock). Aux lines up with mark on seal housing (about 3 o'clock) and crank lines up with mark on seal housing (about 12 o'clock).

Take care

Where is the fuse box located on a volvo 740 1991 model

on the 1991 740 the fuse box is located behind the black ashtray, unless you have a 740se, in which case it can be located on the side near the door, like in the 760turbo and 780bertone turbo. good luck :)

How to replace a Left turn signal on a 1991 Volvo 740

Hello. here is how you replace the front turn signal assembly on a 90-92' 740. First, twist the the black plastic collar loose to disconnect the wiring harness from the assembly. Second there should be 2 10mm bolts holding the assembly in place. just take the nuts off the bolts, then carefully pull the assembly out. Reverse the directions to install. should take about 5mins, unless the nuts are totally rusted. if so use some BP Blaster. Good luck :)
