PS bracket issue on '71 - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ah crap sorry i didnt even pay attention to that my bad

Jimbabwe · 01-27-2013, 09:20 PM

Dan, I was also going to ask the guys at Davis Speed Equipment; the ones who are selling the brackets on ebay. They may sell the pump as well, or at least have more info regarding getting one.
I was out in the garage before looking at their brackets, and there does seem to be a good amount of fore and aft adjustability--both with slots on one part, and three hole positions on the other--so if you wanted to simply swap to the separate alternator brackets and use this for PS, that may help with your issues. Of course if you don't need to go that far there's no need to spend the money unnecessarily. I can shoot some pics of the brackets if you want.

Malamute · 01-27-2013, 10:16 PM

Let me do some digging on my end before you have to take any pics. Thanks for the offer though.

Malamute · 02-02-2013, 03:55 PM

So once I got the PS pump and alt pulled what I have is the alt is mounted on the front surface to the current combo bracket. If you look at this pic of the original mount it was mounted to the back side of the alt. That appears to be the distance that the pulley is out of line.

The one problem I think I may have is that the lower mount is fixed and I don't see how the alt will line up with the lower bracket if I move it forward. I haven't pulled the combo bracket yet, I plan on doing that here in a bit to see if they line up.

Malamute · 02-02-2013, 07:17 PM

Pulled the bracket and it still doesn't line up. It's the lower bracket, it is a full 3/8" posterior to the crank pulley. I'm stumped.

Jimbabwe · 02-02-2013, 07:36 PM

How about a straight (flat) top bracket and a bent (forward) lower...if that exists?

Malamute · 02-02-2013, 07:48 PM

I'm not sure Jim. My GM hookup isn't back in town or I would have had him come check it out. Hopefully he can come tell me what I need with regards to a alt/ps setup so I just have to pick up one bracket for everything.

Andy4639 · 02-02-2013, 08:56 PM

Are you sure you have the crank pullies all the way on? They look like they arn't pulled up all the way.

I just redid my timing cover and this was what I ended up with.

Malamute · 02-02-2013, 09:08 PM

I see what you are saying Andy. I just got the truck and have no idea on the history of the crank pulley. That would explain why everything else is out. I see no way the alt pulley can line up with the crank.

Andy4639 · 02-03-2013, 10:15 AM

It's hard to say by the picture but on mine which it's a V-8. I can't get my fingers between the pulley and the timing cover.

Malamute · 02-03-2013, 11:13 AM

Well, I'm a little out of my element with this one. How do I check to see if that's really the problem and if so, how do I get it back in line? Thanks.

**lolife99** · 02-03-2013, 11:29 AM

Didn't the alternator and crank pulley line up BEFORE the p/s conversion started?
You can't compare anything on an inline 6 with a V8.

I wish I was there to look at it.
Any better pics?

Malamute · 02-03-2013, 11:42 AM

No better pics at the moment. Yes, they did line up before and Keith said the lower mounting bracket for the alt is the same, just the upper mount different but the lower mount is fixed, no way to move it forward. I'll see if I can get one with my phone in a bit.

I highly doubt the crank pulley has ever been moved, it was simply a removal of the original strap bracket on the top and replacement with the larger bracket. Hopefully some better pics will shed some light on this.

Thanks for the input.

Malamute · 02-03-2013, 01:02 PM

Trying to get a pic from my cell phone on here but can't figure it out.

n2billet · 02-03-2013, 01:19 PM

These are the best pictures I have......Dan you did install the single pulley right?

Malamute · 02-03-2013, 01:29 PM

Not yet, that was my plan but before I go to the trouble of taking it off I lined the alt up on the original mounting brackets and it's still quite a bit posterior to the crank pulley. I think I'm going to sit on it until my friend can get over here and take a look. I would prefer to simply get the right setup for the alt and PS and do it once.

I appreciate the help.

Malamute · 02-09-2013, 09:40 PM

Well, I think Andy was right....it's the crankshaft pulley. The problem is I can see no way to get it back flush. It looks like it's the one piece shaft that is press fit on the balancer. I'm not sure on the history if it was pulled before but I know the outer piece and the inner portion can get separated if they are pulled a certain way. I hope I haven't messed something up the little bit that I drove it!

I'm trying to get a pic of the front of the pulley uploaded but it's not working at the moment, I'll try to get it on in a bit.

Malamute · 02-09-2013, 09:45 PM

Got it. Let me know what you all think. I guess the only good news is the PS bracket will work after all. I just need to get this crankshaft pulley figured out.

**lolife99** · 02-09-2013, 09:50 PM

Maybe you can contact this member.
He has a 250 with P/S.

Malamute · 02-09-2013, 09:52 PM

It's not the PS that has me at a stand still unfortunately....it's the crankshaft pulley.

**lolife99** · 02-09-2013, 09:56 PM

Is the pulley a combo unit with the balancer?
It appears (by the non-orange painted areas) that the pulley has worked its way forward.
Just recently.
It's probably a good thing you discovered this issue.

Andy4639 · 02-09-2013, 09:58 PM

I know we are talking 6 here but this is mine from a few weeks ago on my 305. There is no shaft visible at all.

U should only have about a 1/8" to a 1/4" of the crank pully extending past the timing marker's edge. I think you have the pulley set on back wards. The first pulley should be cuped over the crank pulley itself.

Andy4639 · 02-09-2013, 10:06 PM

This picture is no gap between the crank pulley and the alternator pulley. The power steering is the outter one on the 305. You may even be missing one of the pulleys al together also.

That's what it appears to be. From the front you can see that there isn't a bolt holding it on. With minimal driving do you think I have done much damage? I know it could have been really bad if I had driven it for long periods. TBH, I probably wouldn't have found it if the belt hadn't come off twice.

I guess my next step is to pull this and see what I will need to do for a replacement.

I didn't put it on so I don't know if it's on backwards or not.
