Description

SPECIFICATAIONS
The inventive idea is a way in which you can couple a drive assembly to a
power head and
create a more powerfull, durable, operator comfort and control and better
safety devices.
This drive assembly is coupled up with a stihl 026 power head. This power head
allows us to
power a 6" grinding stone at a recommended speed of 6050 rpm's, with lots of
power,
anti-vibration, resulting in operator comfort, superior inertia brake assembly
and throttle
lock which adds to the safety features.
This inventive idea is easily mounted to the power head. It's one piece main
frame design
allows for easy installation and removal, easy belt adjustments and a well
secured mount
with two studs. It is driven by a centrifical clutch belt drive system with
steel and cast iron
pulley for long belt life and less slippage. The driven shaft is designed for
easy installation
and removeability for service.

Including
2 Studs which mount to Power Head Stihl 026.
PICTURE Z.
Shows 3 piece Frame as welded together A,B,C to make one solid unit. A
represents where
unit is mounted to Power Head. B shows Bearing area fully bored through that
section for easy
installation of Bearing D for self alignment. Section C shows Bearing area
bored with a stop at
the back.

Shows Driven Shaft via V Belt including all parts, Shaft, Bearings, Spacers,
Drive Key,
Pulley, Collars, Left Hand Thread N ut, Belt & Guards.
PICTURE 4.
Shows Picture 3 inserted into Picture 2 in working order.For installation,
take one Bearing D,
insert it into C side frame. Install Guard E with screws F to hold Bearing D
from moving. Now
take Shaft H & install one Bearing D lit; Spacer I & woodrufl' Key J. Insert
'Threaded end of
Shaft into Section B of Frame, lower Pulley K between B & C section of Frame &
slide Shaft H
through Pulley K & into Bearing D in section C of Frame. Be sure Key J fits
into Pulley K &
slide Shaft fully in. Install Spacer L on Shaft then install one Collar M on
Shaft H. Install
Grinding Wheel P on Shaft H. Install Collar M on Shaft H. Thread on Left Hand
Nut N onto
Shaft H & tighten. This pulls everything to the right hand side to bring it
all togefher into one
solid spinning shaft. Now install Belt O into Pulley K. Instal( Ciuard G onto
B side of Frame
which is held by 3 screws F. Two Screws F are located on Frame B & Une Screw F
is located on
Frame C. 'This keeps B & C from spreading away from each other. Now this unit
is fully
assembled & ready for Installation onto Power Head.
This is a Kit which converts a C.'hain Saw into a Portable Gas Grinder. This
idea can be
made to fit multible Power Heads.
