Re: TB removal and then some!!!
 

Went to HD today for 8ft shop light bulbs......and across the isle were the fire extinguishes......the lighting worker there told me that they just came in....so I made another purchase.....here is the info for those interested.....
A nice compact extinguisher for "Autos".....good for 12 years or one time use.......6 year warranty....all for $17.88

DOT approved.....

great size IMO.....will fit nice in the ZR-1

FYI.....check the bottom of your extinguisher before purchasing as I was told.....the date of manufacture is right there....here you see 2018....brand new and current.....can't do better than that.....

Very cool. I have a HD kitty corner from me.

Re: TB removal and then some!!!
 

Tom what is HD?
The only HD I know is Harley Davidson.

Re: TB removal and then some!!!
 

Home Depot.

Re: TB removal and then some!!!
 

Sorry Big John......I should have known......;) Dom knows......:-D

Re: TB removal and then some!!!
 

Cool that is where I purchase ice melt and lightbulbs.
I find their lumber of poor quality!

Re: TB removal and then some!!!
 

Don't buy the lumber.....[emoji16]

Also a nice feature is the plastic bracket.....when locked makes for the extinguisher to stay "flat" and not slide allover wherever stored...when the vehicle is in motion....also size comparison with my garage unit....

To nice of a day not to take the ZR-1 out for a ride......temps were up to 79* here today.....running great as it has been.......idle is still perfect each and everytime coming to a complete stop.....so no issues there.....hopefully I'll never have to touch the TB again......lol:)

With all of the chat about the clutch neutral safety switch......since I am not one for cutting into the harness to bypass the switch......decided to pick up a spare.....just in case.....always better to have than not to have......

Re: TB removal and then some!!!
 

Dry chemical fire extinguishers are cheap, but if you use them they will make a god awful mess of your car and garage. Dry chemical goes everywhere & is really, really hard to clean up. The chemicals waft through doorways & spread everywhere. Plus it will permanently damage electronics....
I went another route and purchased a large 10# CO2 fire extinguisher for the garage & a 5# CO2 for the kitchen. CO2 dissipates into the air and leaves no residue of any kind (no chemical clean up). It also does not hurt electronics. The only damage you will have is from the fire.
The CO2 extinguishers are more expensive, but they will save you thousands in clean up if you ever have to use them.
Many years ago I used a dry chemical fire extinguisher to extinguish an engine fire, it was a very expensive mistake....

Re: TB removal and then some!!!
 

If anyone is interested, this is by far the cheapest place I found to get the CO2 fire extinguishers:

https://www.webstaurantstore.com/buc.../47245600.html

Shipping is not real cheap because they are a pressurized gas & there are limited ways to ship them. I also purchased a really nice "boat" mount that is child resistant for only $30 more.

Re: TB removal and then some!!!
 

Ever since I've owned the 94.....my AC has never been really cold and sometimes it just felt like regular outside air coming through the vents......just never got around to checking things out.....until now....
My compressor doesn't engage at all.....(I have not jumped the switch).....although the AC clutch turns freely inside the pulley..
And I don't have the "low freon" code.....so I did some research and decided to change out the AC clutch bearing..... I have also noticed for about the last 6 times or so that I used the Z.....that upon startup I was hearing a bearing noise that would last for a few minutes and then disappear..... I thought maybe it was the water pump....but no leaks there....and it wasn't the alternator.....so I'm thinking could it be the AC clutch bearing....
I figure try that first without removing the plenum....and if that doesn't work....well then...... I would assume some other parts may be defective.....or the compressor would be shot......
So here are some pics of the removal of the parts necessary to get to the clutch bearing......
In pic #1 & 2....
I had to figure out the best way to lock the compressor in order to remove the 10mm bolt in the center of the pulley....as you can see a large vise grips was used to keep anything from moving......and a 1/4 ratchet and 10mm socket to undo the bolt....as you know.....there is very little room to maneuver anything in that space.....
Pic #3 shows the AC clutch removed....and you may also be able to see a snap ring in place to keep the pulley secured......
In pic #4......it is highly unlikely that the pulley will just slide off with hand pressure....so again with limited space I used the 2 hammer method.....rotating the pulley after a few hammer taps....it finally slid off.....Attachment 7781Attachment 7782Attachment 7783Attachment 7784

Re: TB removal and then some!!!
 

Pics #1 & 2 show the parts on the bench and both sides of the bearing....
Pic #3 shows a close up.....which appears to be the original bearing.....
Pic #4 & 5 show the new replacement bearing that will be installed....
And pic #6 shows the coil which looks to be in fine shape.....not melted or destroyed like from what I read......could happen and it is a real possibility.....so I lucked out....

I don't have any AC knowledge.....so I'm learning as I go....
Next is to punch out the old bearing and install the new one....and hopefully that will correct the issue.....we shall see.....[emoji16][emoji16]Attachment 7785Attachment 7786Attachment 7787Attachment 7788Attachment 7789Attachment 7790

Re: TB removal and then some!!!
 

Finally got bearing out today after a soak overnight with WD40.....new bearing went in just fine.....used some Loctite to make sure it stays in place...
Another option for bearing install would have been to put the bearing in the freezer for a few hours to contract.....and then slightly heat up the inside of the pulley evenly with a small torch to expand.... and the bearing will (should) drop right in....
Also old bearing was shot.....just plain worn out...... finish the install tomorrow......the compressor should now work......Attachment 7797Attachment 7798

Re: TB removal and then some!!!
 

I know u are trying to avoid removing the plenum, but have u checked the ac clutch harness connector? They are notorious for cracking and disintegrating.

Re: TB removal and then some!!!
 

If you go back through the heart of the beast articles I did an extensive rebuild on the AC system for our cars and how to rebuild the AC compressor

Re: TB removal and then some!!!
 

FWIR......when I did the plenum pull last summer......all appeared to be in good shape.....of course if this bearing replacement doesn't correct the problem....then I will have to look elsewhere.....I do have a kit to rebuild the compressor if necessary and would then be checking the clutch harness connector as you suggest......but right now I am leaning to the clutch bearing....you could really feel the difference between the two......so hopefully this is the answer......

Re: TB removal and then some!!!
 

Dave.....I did read that article before.....which is excellent and that is what prompted me to purchase the rebuild kit mentioned in the above post.....but I'm hoping that the clutch bearing replacement will be the answer.....I will know tomorrow for sure...….:)

Re: TB removal and then some!!!
 

If you need any help please feel free to send me a message and we can set up a call I’ll be happy to what I can.

Re: TB removal and then some!!!
 

Thanks Dave.....it is appreciated.....:) If I run into a problem....I will take you up on the offer.....:)

Re: TB removal and then some!!!
 

Well Dave....looks like I'll take you up on that offer.....will send you a PM....
Partial success today.....in that everything went back together......AC clutch seems to rotate all of the time now.....and although the air in the cabin was cool when I first started the engine.....it was just warm....freon gauge shows that I might be overfilled......and there is slight noise being heard now.....low pressure tube is not cold to the touch.....

Well it's been awhile since I've posted up....I haven't run or evan started the 94 since last June....ever since I did a number on the AC Compressor...

Have a new one ready to install and noticed when I slightly lifted the plenum....the gaskets ripped on both sides....kind of disappointed with that as they only had a few thousand miles on them..

Ended up pulling the plenum completely....will order new gaskets or reuse my originals....[emoji849][emoji16]Attachment 9601Attachment 9602Attachment 9603Attachment 9604

Started working on the 94 again and made some progress.....the radiator should is ready to come out....those 6 screws were a PIA as many have mentioned....did not have to remove anything on the passenger side....but removed items on the driver's side to gain access to those 3 screws...also a chance to clean the leftside well with parts removed...
Done for the day....will remove the shroud tomorrow....just have to remove the small hose connected to the top of the radiator in order to lift the shroud out....determined to get the AC operating once again and to start the engine once again since June of 18....
Still need to change out the accumulator....check the condenser and the radiator and I guess the oil cooler...
Making progress....[emoji16][emoji16]

Horn cleaned....
I imagine the next pics are a vacuum tank.....cleaned....

Inside the left front well....
Before cleaning and first preliminary cleaning....should come up good after I'm finished....
All 6 side screws out....
Some of the wrenches needed to do the job....would have been a breeze for the top screws on both sides with a 7mm ratchet wrench....but couldn't find one locally....also 9/32" socket or wrench will also work....
Was too hot to go out to the 74....so the portable garage AC unit did good in the above 90 degree temps today...garage was in the low 80's and comfortable....[emoji16][emoji16]Attachment 10258Attachment 10259Attachment 10260Attachment 10261Attachment 10262Attachment 10263

Progress made today.....shroud is out with the help of my wife.....once we cleared the hood hinge support on the driver's side....it was just a matter of getting the correct angle on the passenger side.....a few tries and it slid right out...
There was and is some debris in there....but not bad for 70,000 miles...will need a good cleaning....
Interesting factory markings on the shroud....might still have to undo the fan setup to gain full access to the accumulator.....going to see if I can wiggle around it....
Fins on both the condenser and the radiator look to be in excellent shape...
I imagine the oil cooler is just as good...more cleaning to do....and then reassembly to follow.....[emoji16][emoji16]Attachment 10269Attachment 10270Attachment 10271Attachment 10272Attachment 10273Attachment 10274

Re: TB removal and then some!!!
 

More progress today.....oil cooler lines came off with my removal tools shown in the pics....have a new set coming from Jerry's.....but might leave the fittings in the block...
Everything has to be cleaned and the bent fins at the bottom of the cooler can be straighten out....still deciding if I am going to replace the AC condenser with the new one I have....or just get the original pressure tested....
Will most likely continue on and take the radiator out since I am in it this far and replace all of the hoses....this will also make changing out the accumulator real easy....as I'll also remove the fans and the crossover pipe for a thorough cleaning and paint touch up where needed.....my thermostat is or was working fine and I found out the reason I had a major temp spike on the turnpike from a few years ago....as there was a huge plastic bag that got sucked up into the front of the condenser...therefore blocking any air flow through the system....
Some pics...

Just removed the oil from the oil cooler and from my markings on the container....it appears that the cooler holds just under a quart of oil....I'm estimating that I have about 27-28 oz of oil in this container.....
Talk about being dark....this oil is very dark....but did not appear to have any particles mixed in with it....
Thinking about pouring fresh oil in there to slush around and empty....do that for a few times to "clean" it out...
Some fresh paint and will be looking like new....
Second marking in second pic is 16 oz...will have to do a full measure for sure...Attachment 10294Attachment 10295

Re: TB removal and then some!!!
 

Tom,
Given the way it is designed the oil cooler can be a challenge to thoroughly flush clean of old oil. I’ve had pretty good results filling it with solvent and shaking it multiple times until drained solvent ran clear. A lot of work. Next I have clean one I plan to connect it to a solve vent and let run for couple of hours first.

Re: TB removal and then some!!!
 

Hello Phil,
To be honest, I didn't even think it would be good to use any type of solvent. What solvent do you recommend???

Re: TB removal and then some!!!
 

I use mineral spirits from Home Depot

Re: TB removal and then some!!!
 

Thanks Phil, I have used that before, but never thought to use it in the oil cooler. A trip to HD on Sunday.

Re: TB removal and then some!!!
 

Would like to thank Phil for his suggestion of mineral spirits to flush out the oil cooler....worked great....completely cleaned...[emoji16]
