DESCRIPTION
The GB745/204 Split Riveter Pneumatic-Hydraulic Installation Tool is designed specifically for the efficient
installation of a wide range of blind rivet and lockbolt fasteners. This tool’s unique "split" system provides
the operator with a lightweight ergonomic tool for a fraction of the cost of other cumbersome power rigs. It
has a .500" (12.7mm) rivet setting stroke with a rated pull load of 3600 lbs. (16.0 kN) at 90 psi. (6.2 bar) air
pressure at the air inlet.
The GB745/204 comes with 8 ft. of hose and a remote actuator. The GB204 cylinder when held in your hand,
weighs just 2.0 lbs! (.91 kg) while the entire split riveter weighs 12 lbs. (5.44 kg).
The GB745/204Split Riveter operates on a wide range of air pressure, with 90 to 100 psi. (6.2-6.9 bar)
providing maximum efficiency. At 90 psi. (6.2 bar) air pressure the GB745/204 does not exceed 81.5 db (A)
and consumes 6.0 cfm at 20 cycles a minute.
This tool accepts all patented GB204 style nose assemblies.
MAINTENANCE
WARNING
:
EXCESSIVE CONTACT WITH HYDRAULIC OIL AND LUBRICANTS SHOULD BE AVOIDED.
WARNING:
MAINTENANCE PERSONNEL
MUST
READ AND UNDERSTAND ALL WARNINGS AND CAUTIONS.
WARNING
:
DISCONNECT TOOL FROM ITS AIR SOURCE BEFORE PERFORMING MAINTENANCE.
The performance of any tool depends upon good maintenance practices. Following these minimal
requirements for service and care will extend the life of your tool.
*Only use an air supply set at 90-100 psi. (6.2-6.9 bar) equipped with a filter-regulator unit to prevent wear.
*The tool will eventually lose some hydraulic oil. Keep the hydraulic system full and free of air by using the
air bleeder (704153) on a regular basis.
*Proper care by operator is necessary in maintaining full productivity and reducing downtime. Read all
applicable tool manuals and nose assembly data sheets prior to operating tools.
*Keep nose assemblies, especially jaws, clean and free of chips and debris. Lube jaws and collet surface
that jaws ride on with light machine oil.
*Check tool, all hoses and all couplings daily for damage or air/hydraulic leaks. Tighten or replace (if necessary).
*A complete overhaul can be achieved by the use of Service Kit 745204 which contains a complete
set of o'rings, back-up rings, screws, washers and gasket.
WARNING:
This tool incorporates a patented hydraulic
relief valve. When overhauling tool, o’ring (A-
287), back-up ring (401101), retaining ring
(400936) and spring (50806) must be replaced.
Failure to do so could result in SEVERE
PERSONAL INJURY!

HYDRAULIC THREAD PREPARATION
IMPORTANT:
Be sure to use thread sealant on all hydraulic fittings, Loctite® 30534 or similar Teflon® infused pipe
dope is recommended.
CAUTION:
Teflon tape is an excellent thread sealer, however, if it is not
properly applied, pieces of Teflon may enter the hydraulic system and cause malfunction or damage.
Use 1 1/2 wraps of tape on each thread. Cut off all loose tape ends. Tighten until fitting feels snug and
then go 1/2 to a full turn past that point.
CAUTION:
Over tightening can easily distort the threads.
