Complete DIY carburetor bushing installation kit allows you to install bushings on your Rochester Quadrajet primary throttle shafts yourself. This kit works on all carburetors with 5/16" throttle shafts. Kit contains everything you need to correctly do the job yourself. The key to this kit is the specially machined piloted drill that aligns itself with the existing carburetor throttle shaft bore. Complete and detailed instructions are included. Easy to do.
Top carburetor rebuilders use and recommend this method of bushing installation. Accurate, Complete and FAST.
My last order, I purchased your 5/16 bushing installation kit. Best tool I ever bought, ever. So quick and accurate I cant believe it. I have used different ways to install the bushings for many years, But this is the best. By the way I am 71 years young and have done a lot of carbs. Your Co. is the best.
Thanks, Kenneth T.
Enough supplies included to install bushings on 3 Quadrajet carburetors. Bulk 10-pack bushings are available separately (#4311).
Most Quadrajets have worn primary throttle shaft bores. This excessive clearance allows unfiltered air to enter the engine and since the carburetor "doesn't see" this air, it can't compensate for it with the proper amount of fuel. A worn shaft can cause an erratic idle and light throttle issues.
Quadrajet Carburetor Bushing Kit includes:
1 Specially machined piloted drill
1 Drill stop collar
6 Oil impregnated bronze bushings
Aluminum bushing driver
12 Throttle shaft screws (for Quadrajet, Dualjet carbs only)
Complete instructions included
Replacement parts available separately:
#4311 - 10 pack of throttle shaft bushings
#4212 - 20 pack of Quadrajet throttle shaft screws
All Rochester Q-Jet carburetors
Note: Only for use on primary side of Rochester Quadrajet carburetor.
Also works on the following carburetors (w/exception of throttle screws supplied)
Rochester B, BC, BV
Rochester 2G / Two-Jet
Rochester Monojet (Note: Install throttle linkage side bushing first. Other bushing will need to be trimmed if casting narrower than bushing.)
Installation instructions for 1bbl carburetors: Bore hole and install bushing on ONLY one side before boring out second hole. If you try to bore out both holes at the same time, you will defeat the purpose of the special piloted drill and risk having non-concentric bushing installation.
For 5/16" throttle shafts
Electric hand drill
Small hand file
A Note About the Special Machined Drill Bit Included In This Kit:
The drill has been ground down to fit into the throttle shaft outer and inner bore. The actual cutting edge on the drill is approx. 1/2" from the bottom of the drill flutes.
