Big Brother is going 3G


Recommended Posts

Yippee!!!! Glad you have all the pieces. I'm along for the ride, although my grandtwins arrive tomorrow and I'll be playing with a French truck for the next week. So if you need me you have my cell and can text me. Good luck!!!! :nabble_crossed-fingers-20-pixel_orig:

Okay, ready to proceed to 3G swap!

:nabble_anim_jump:

I restored the C-610 connector, everything works, so now I can go on with the 1G/3G replacement.

Don't be surprised if it takes some time... We have family visitors at the chalet, and the process will be frequently paused.

And don't be surprised too if I have couple of questions during the operation.

:nabble_smiley_blush:

I'll take a lot of pictures and will document each step, hoping this will be useful for other members.

Stay tuned!

I’m tuned in, but in no hurry. I understand going slow and having visitors.

Yes, that/this is the latest.

I'm taking a lot of pictures, so I'll be able to document a clear step-by-step (later).

But for now, I need your advice.

This morning, I took out the 1G without issue.

I still have to prepare the 3G with tapping the tensioner bolt hole, and swap the pulleys.

Before going further, I've put the 3G in place, just to verify the fitment. And I realize that I'll hit a wall with the pulley.

This is a picture with the 3G in place. Fits very well:

BUT, in order to verify the belt/pulleys alignement, I placed the V-Belt around the 3G serpentine pulley.

I goes all around, well centered... But the 3G is already at its maximum tensioner position.

So if I install the 1G pulley on the 3G, I won't be able to tension the belt, it will stay lose.

Here is a picture comparing the 1G and 3G pulleys diameter:

Question:

Can I simply install a new shorter V-Belt?

If so, how much shorter than the current one? The current one is 39-3/8" length.

Ohhhh! I love the clocking on your 3G. Everything is easily accessible.

Anyway, yes you can use a shorter belt. For every inch of a shorter belt the distance between the pulley and belt decreases by ~1/2". So if you currently have 1/2" of clearance you need a belt 1+ inches shorter, the "+" being so you have some room to adjust. So maybe 2" shorter?

Perhaps buy two or three belts and return the one(s) that don't fit well?

Gary, 3G in place. Starting test.

Big Bro starts, no squealing.

Seems a success BUT... the voltmeter goes wrong side.

I'll have to reverse two wires in the 3G harness.

I suppose the ground Y/LG and the Y/W ?

Maybe the Voltmeter studs were reversed...

EDIT:

Or, maybe just swap these two wires in the cluster connector?

Yes, swapping pins should correct it without any underhood work! 👍

Yes, swap the R/O and Y/LG in the cluster. Apparently the gauge is backwards. I'll check that out tomorrow.

But congratulations!!!!!
