 |
|
I am learning loads from here.
I've pulled out the bushing by hand like a cork out a bottle.
Screwing in a tap (from basic tap/ die set) 8mm or something grips the bush enough. As not everyone has a drill press or is lucky to get it all square.
Yes an old post, but I still read it and enjoyed it.... |

Re this Post: Sun Feb 28, 2010 9:40 am Post subject: HOW TO: Re-Bushing Kadron Throttle Bodies
Not trying to hijack/resurrect an old thread but I wondered if when filling the hole in the carb - do you leave the wire in the hole or just use it to poke JB into the hole?

" If I'm going to be modifying the carb for vacuum advance, I cut a small piece of .0403" aluminum wire, coat it in JB weld, and fill the little hole in the throttle body as shown. Don't fill the wrong hole or your throttle body will be instant junk! This creates the proper vacuum signal for the VW distributors when adding the port for the advance on the case of the carb."
Fascinating information. Thanks for passing on the knowledge you have learned! I Am Very Grateful.

| Also I'm running an Msd on my stock sp motor. Can Msd be ran with Kadrons since I hear people say you need vaccum advance? I ran across a 070 dissy yesterday in the parts I bought I believe it's a dvda is this correct? Can it be used with the Kadrons after I clean and inspect it. Thanks! |

| I'm about to do my 3rd set but this will be my first at redoing the bushings myself. I want to try the dent puller method on the bushings. I like how aj's bushings felt but havent tryed Jeff's yet. I'm at a stopping point cause the throttle plate screws where froze so I carefully drilled them but lots track of my easy out? Can bushing be bought from eBay? |

Oillite bushings are a powdered bronze, they absorb oil when heated so they are fine for your cheap electric motors or vacuum cleaner, but wrong for exposure to fuel like Mark said they will leak like a sieve after the oil is flushed out.

I actually saw in a couple other threads people saying they were junk on smaller carbs so I bought bushings through kaddis shack. Haven't put them in yet, to busy building the car right now lol.

I know this is an old question, but the bushings referenced above are junk. If you use those the fuel washes the impregnated oil out. Use the 932 bronze ones. I buy them at 5/16 ID and 7/16 OD and use that size for most bushing work except for special cases. I turn down the OD to fit the hole I need to put them in. Most of the time they need to be about 0.375-0.380 for bodies that need to be machined out, like ICT, KADRON, PDSIT, etc... and for Stock 34PICT carbs, they need to be closer to 0.385 or 0.395 on models that had a positioner lever. I make them a press fit, but if you need to use loctite due to errors, use a retaining compound.. there are several versions of it.
The replacement bushings are garlock I think, the ones referenced, and they wear quick in my experience. Custom bushings made from the 932 bronze are the way to go. |

| Cannt the bushings just be tapped and insert the tap into a dent puller and pulled out? So you can just drop in the new bushings. And instead of ib weld I recommend the green loctite gene berg sells. Gb-9020c |

Will that bushing size work on a Solex 34-Pict also, or is that a different size?

Here is a link to some:
http://www.mcmaster.com/#sleeve-bearings/=d6rnst
Couple questions:
I just want to confirm that you do not ream the ID of the installed/finished bushing, right? What kind of rotational drag/resistance do you have on the shaft and bushing? Is there any measurable play in shaft? What made you select these bushings?
I'm planning on doing this on a original 30 pict 3 carb and believe the bushing sizes are identical (unconfirmed).

They are made by INA and any bearing dealer should have them. I bought mine for 2 bucks a piece.

I'm with you 57Baja! We as machinists are a fussy bunch by nature it seems. We are sort of forced into that mold by picky inspection departments and ultimately picky customers. Sometimes machinists are more enamored with the process than the end result. But in the end the customer really doesn't care most of the time how you remove the material as long as it meets their specs and provides expected results.
I admire your attitude. You provided proprietorial information and left yourself open to criticism and take it all as constructive. Bravo well done!  |

All tooling/fixturing is produced on the CNC's and has been for about 15 years...... About the same amount of time it's been since I used a boring head....... Sadly, the craftsman side of machining is slowly dieing......... Or being outsourced......... |
