Re: Restoring Rusty
The biggest issue is to get one with a wide temperature range, so 1) it doesn't get tight when cold and 2) doesn't run and drip when hot. That's why I say a lithium grease.

just bought 14 oz Tube of Lubriplate 630-2 NLGI No. 2 Multi-Purpose Lithium Grease from Sky Geek, it always stings a bit when you pay more for shipping $12 bucks than the actual product $6 bucks. Oh well |

The good news is that tube will probably last you forever. It's good for all kinds of things -- cars, motorcycles, toy trains, CD-ROM drive tray sliders, garage door openers, barbecue rotisserie motors, lawn mowers, etcetcetc. If it has gears or bearings or bushings, and doesn't have active lubrication from a sump (like engine, trans, transfer case and diff all do) then it's the way to go. But it doesn't take much. No need to glop it on. A 14 oz. tube is a lifetime supply for most people. I'm still using a 1-lb. tin of it my father gave me 50+ years ago.

Re: Restoring Rusty
Oh, BTW, be careful with that stuff. If you drop a glop of it on the floor, people will be losing their footing on that spot for the next hundred years no matter what you do to wipe it up.
Use very sparingly.

Re: Restoring Rusty
picked up some Dormans' BRAKE & CLUTCH BUSHINGS from O'Reillys' for $4.00 bucks (two pairs of bushings from LMC Truck would run me $23 bucks)
The package is for FORD / GM so you know what that means? It don't fit good neither of them? LOL On the back it reads: Ford Cars 1994-73 GM Cars and Trucks 1995-55 but they don't tell you which is which, AWESOME! I believe two of the three pairs might could work. I say might could, cause one pair fits kinda snug (like the original brake one did) the other fits a bit loose (like the original clutch one did) HOWEVER questions being. - Was the original brake one snug cause it was rusted and dry as a bone, or is it supposed to be that way? - Was the original clutch one loose cause it was deteriorated and worn out, or is it supposed to be that way? Better question is how should these fit? Should the metal sleeve rotated freely in the plastic bushings or should it be snug in there and not move? Who knows? |

Re: Restoring Rusty
The flange on a bushing points at the part with respect to which the bushing should stay stationary, and away from the part with respect to which the bushing should move.
So in both of those, the shaft should rotate within the bushing.

Re: Restoring Rusty
also picked up this PEDAL AND SHIFT LINKAGE BUSHING KIT for $7.00 bucks also by Dormans'
DODGE/FORD/GM... hmmm even worse, LOL CONTENTS (Russian roulette style) 3 Selector Lever Bushings 1 Throttle Valve Bushing 1 Pedal Bushing ... again no idea which is which, might as well say "STUFF" I hope the white one on the bottom will fit / work in the top hole of the clutch pedal to receive the metal rod/linkage, we shall see FYI - LMC Truck does not carry this part (they hardly have what I really need, they seem to specialize in what I want though, if you get what I'm saying) Do I dare go to the Stealership for these?! |

Re: Restoring Rusty
one of the challenges of putting something together where it could have had parts missing even before you touched it, is not knowing what's missing
Could someone tell me please what went on this stub on the clutch pedal? (thanks for nothing GM Service Manual) |

Re: Restoring Rusty
Yes, the safety start switch that will only let the starter crank when the clutch pedal is depressed (no start in gear / clutch out ).

Re: Restoring Rusty
Greg, what goes on that stub on the pedal is a big tension spring. What it does is hold the pedal in the fully up position, so the the weight of the pedal doesn't cause the throwout bearing to constantly ride against the clutch fingers. But it also increases the pressure to disengage the clutch a bit. The throwout bearings weren't intended to spin constantly when our trucks were made. But I think most modern throwout bearings actually do spin all the time.

Re: Restoring Rusty
I believe the white piece which is the start safety switch thing you are refering to goes into the second hole from the top on the pedal, the first hole from the top being for the down rod linkage

Re: Restoring Rusty
Greg, I found the following picture that kinda shows what's going on:
http://s181.photobucket.com/user/Die...ts013.jpg.html It's a 72, but the basic idea is the same. Sort of an over-center design. It may be that those springs on your z-bar effectively serve the same purpose.

Warning this spring is one very strong spring they are a real pain to deal with. Hook the top first then use a brake tool to "stretch" it over the pedal pin. It's a bit easier if you have the pedal on the floor.

Re: Restoring Rusty
Hey, Gregski:
I found these in my PDF illustrated parts book, clipped the pages out and uploaded them to my site for you. Download them so I don't need to leave them on my site forever. I can also look up part numbers for specific parts if you need it. Sometimes the best way to find a part is just google the GM part number. http://users.rcn.com/weyand/smalls/7...utchPedals.pdf http://users.rcn.com/weyand/smalls/73-78Clutch.pdf You might also want to purchase the CDs of the parts books. I copied the CDs to my machine, and can scroll the whole book. http://horn-relay.dvautoparts.com/di...s-s-tiixsn8agk

Re: Restoring Rusty
Sorry, I thought the switch was on a post, ( been ten years since I had to fix my last manual truck), didn't see yours hanging below the dash anywhere and thought it had been deleted ( ie.. "Bubba fixed").

Re: Restoring Rusty
Hah! Just call me "Bubba" then because I absolutely hate those clutch start switches. They are the 2nd thing I remove from a new to me vehicle. The first thing you ask...... those damn silly buzzers.
