    Need photo of mounting arrangement for driveshaft center bearing

    So let me see if I am understanding this correctly. It looks like from these pictures that this U shaped bracket is about 4 inches in width (front to back) and at the back it is 3.375 inches deep and 3 inches deep at the front. Is that correct?

    Need photo of mounting arrangement for driveshaft center bearing

    Hello 84GMCSierra Thanks for all the photos. Can you tell me an approximate height of that U shaped bracket that is riveted to the crossmember of the truck's frame? I.E. the U shaped bracket that the center bearing bolts to. I am trying to figure out the angle that the driveshaft should be at in...

    Need photo of mounting arrangement for driveshaft center bearing

    The previous owner built the truck out of two trucks and the front diff ratio is 4.10 and the rear diff ratio is 3.73 so the front driveshaft has never been installed the whole time I have owned the truck. I don't use it for 4WD off road stuff so the transfer case was totally useless. When I had...

    Need photo of mounting arrangement for driveshaft center bearing

    Thanks. That is the transmission mount that I have. The 4WD trans crossmember is quite a bit different so I had to make a spacer to go between the bottom of this mount and the 4WD trans crossmember.

    Need photo of mounting arrangement for driveshaft center bearing

    Hello all I have a 1986 Chevy K20 truck that I am in the process of converting from 4WD to 2WD. I have the rebuilt TH400 2WD transmission mounted in the truck and the original transfer case sitting on my spare parts shelf. The 4WD driveshaft was a one piece driveshaft that went from the back of...

    86 K20 No start, bat & starter good

    There is a fuse down at the bottom of the fuse block that is supposed to be a 3A fuse and it is labeled on the fuse block "CRANK" What does this fuse do? One of the wires going to one side of this fuse goes to the ECM to a terminal labeled 'CRANK IN" and the other wire is a purple wire that...

    86 K20 No start, bat & starter good

    OK, I tried jumping power from the positive battery cable lug on the starter to the S terminal and nothing happened so I decided to pull the starter. Once I got it out it sounds weak when I try to jump it off of the actual battery but then just for grins I had a friend come over and turn the key...

    86 K20 No start, bat & starter good

    Found a wiring diagram for a 1987 series of trucks which would sort of match up with the 454cid w/TBI engine that is in my truck and it seems the red wire is actually orange with a black stripe and it goes to the ECM labeled "Park/Neutral In". The black with white stripe seems to be a ground. I...

    86 K20 No start, bat & starter good

    Well, that didn't work. When I jumped 12V power from the blue wire to the black w/white wire with the key in the On position, I managed to immediately blow the 15A fuse for the reverse lights. Is it possible that there is a starter relay in the system and these column wires through the neutral...

    86 K20 No start, bat & starter good

    I just checked the four wires with a trouble light. Just the blue wire lights up when the key is switched to On. None of the wires get power when the key is turned to the Start position. I.E. neither the red or black w/white or the green wires do anything at all as far as having 12V power...

    Pics of piece I pulled out Here are a couple of pictures of the piece of the neutral safety switch that sort of fell out of the truck. It was mounted on the top of the steering column. It was only hanging on by a small piece of the original plastic housing. Obviously there is still the other...

    Neutral safety switch wiring Thanks a bunch for your reply. However I do not see any purple wires. The neutral safety switch seems to be coming apart as there were loose pieces hanging. Here is the wiring I see on the pieces of the neutral safety switch that I found in the truck. One plug...

    86 K20 No start, bat & starter good

    Good morning all: I have a 1986 K20 that the previous owner added a 454 w/TBI from a 1987 Suburban R20 and I have been experiencing some issues with getting the truck to start. Recently I have had occasions where the starter is not being activated when I turn the key. Previously when this has...

    Where to get replacement glove box lock and latch

    I have a 1986 K20 pickup and the glovebox is missing the latch and lock. So there is just an open hole in the glovebox lid and the lid just flops open all the time. Where can I get a replacement for these parts? I looked on-line but this does not seem like a popular replacement part.
