    Smog Pump Disassembly and Rebuild.

    Well I have something that may (emphasis on may) work - the "shoe kit" for older fj40 smog pumps (04172-40010) that are available through foreign sources. I have yet to dissect my air pump so forgive me if I am wrong about the part on the parts diagram which is referenced in #1) below. Here is...

    Smog Pump Disassembly and Rebuild.

    Thanks for the pics and details. I’ve read in other posts that the vanes are available somewhere but can only be purchased in a lot of 1000’s or so. Do you happen to have a link/searchable product name or number for these ?

    Water pump belt continues to become loose.

    Yes that is ultimately how I get to it when I am working alone. Due being short (5’8”) and overweight I have to jack the front end up so I can maneuver better under the axle. With two people, one person can go near the drivers side part of the engine bay by the windshield and there is a “clear...

    Water pump belt continues to become loose.

    Yes, I have tried that (I want the box end side on the nut), it always comes apart sticking it through the mess of smog crap

    Water pump belt continues to become loose.

    Does anyone know of a Looooong 12mm box end ? By long I mean 2’ to 3’, not 10” lile most “long” 12mm box ends are. The reason I ask is because the rear 12mm on the air pump is a beast to get to on my truck (assume I am not missing something because I am not and also assume my physical...

    Water pump belt continues to become loose.

    Well if I have to get a new pump I’ll probably go OEM for $306 : Power Steering Pump - Toyota (44320-60071) | Toyota Parts I want to perform the tests outlined in the FSM that utilize a pressure gauge to isolate the source of the leak. While the tests and how to come up with them are pretty...

    Water pump belt continues to become loose.

    The PS issue seems like a good explanation, since the belt that continually loosens and is directly under the ps pump. I’ll fix/replace then see if the belt lkngevity improves.

    Water pump belt continues to become loose.

    Ugh yeah I noticed that, down one of the ps hoses, right ? I should address that first and foremost. Those “rebuilt” air pumps arent completely rebuilt - (no carbon) vanes or bearings available. This is probably a disaster in the making. Ok that sounds reasonable. Most seem to convert to a...

    Water pump belt continues to become loose.

    Ok I put a video on youtube showing the air pump and ps pulleys first for about 10 secs and then I move to the water pump. Could you guys take a look and let me know if you can see anything egregiously wrong or if you need a better angle ? Thanks.

    Water pump belt continues to become loose.

    I am not concerned with the tension, I was just showing all the parameters of the problem (ie I have the spec and tool(s)) to hopefully elimnate some possibilities. And I should warn you the spec IS different based on the tool and method. They ultimately point to the same tension but are...

    Water pump belt continues to become loose.

    Here are some pics : pic 1 - All the various belt tension gauges I’ve got. The OTC-Burroughs type is what I try first but will use the others when it proves difficult to use the OTC-Burroughs do to tight clearances. pic 2 - Three different fsm’s with the tension specs. pic 3 - Tension spec in...

    Water pump belt continues to become loose.

    Ah the “crickit” gauge, I have two - one for v-belts and one for serpentine. There is no tensioning spec for that type of gauge given in the FSM. There is only a spec for the Burroughs type gauge given. There is a spec given (for Australian versions of our truck) for another type of gauge where...

    Water pump belt continues to become loose.

    How exactly do you determine if anpulley is properly balanced other than by visual inspection and seeing the “feel” of turning the pulley when mounted to the accessory ? As far as I could see and feel both the wp and air pump turned smoothly with the belt off. The drive pulley looks to be...

    Water pump belt continues to become loose.

    No its 3 paged in why my water pump belt has come loose for the second time in 4000 miles. The first time I had a mechanic at a Toyota dealership put on all three belts. This was when I first got the truck. After 3000 miles the water pump belt came completely loose and had a chunk taken out of...

    Water pump belt continues to become loose.

    I wasnt sure what Rodrigzcrzr was saying which is why we had the back and forth. I wrote out what I do to tension any belt on my FJ60 for clarification .

    Water pump belt continues to become loose.

    Yes I agree - I dont believe it is an issue regarding incorrect tension. I think it is something else. If a pulley is wobbling, is it actually the pulky or thr bearings of the accessory to which the pulley is attached?

    Water pump belt continues to become loose.

    Can you please clarify what you are saying yes to ? Tighten the bottom picot bolt when done or leave it loose ? I cant follow your comments. I have been doing steps 1-5 every time I adjust any belt. That isnt anything new.

    Water pump belt continues to become loose.

    I’m confused - are you now saying to tighten the bottom bolt after setting the correct tension ? That is what I had been doing. I am not having a problem in setting the tension. I know how to do that. I thought you were saying I should try leaving the bottom bolt untightened during normal...

    Water pump belt continues to become loose.

    Rather, maybe the belts were being affected by the fact the bottom bolt was not allowing for some very slight movement.
