INTRODUCTION
This manual provides guidelines and procedures for installing, operating,
and maintaining your conveyor.
recommended spare parts highlighted in gray. Important safety information is
also provided throughout the manual. for safety to personnel and for proper
operation of your conveyor, it is recommended that you read and follow the
instructions provided in this manual.
• Receiving and Uncrating
1. Check the number of items received against the bill of lading.
2. Examine condition of equipment to determine if any damage
occurred during shipment.
3. Move all crates to area of installation.
4. Remove crating and check for optional equipment that may be fastened to
the conveyor. Make sure these parts (or any foreign pieces) are removed.
NOTE: If damage has occurred or freight is missing, contact your Hytrol
Integration Partner.
• How to Order Replacement Parts
Included in this manual are parts drawings with complete replacement parts
lists. Minor fasteners, such as nuts and bolts, are not included.
When ordering replacement parts:
1. Contact dealer from whom conveyor was purchased or nearest HYTROL
distributor.
2. Give Conveyor Model Number and Serial Number or HYTROL factory
Order Number.
3. Give Part Number and complete description from Parts List.
4. Give type of drive. Example-8" End drive, 8" Center drive, etc.
5. If you are in a breakdown situation, tell us.
• General Information
Most HYTROL conveyor drives are supplied with the HYTROL Speed Reducer. Models
4A and 5A Speed Reducers are used with V-Belt drives, whereas the 4AC
and 5AC Reducers are supplied with the "C" face drive.
• Determining Gear Ratio
To determine the ratio and/or the assembly date of a HYTROL Reducer, refer
to the numbers stamped on the end of the output shaft.
figure 4A shows the location of these numbers. AVAILABLE RATIOS ARE
ALSO CHARTEd IN THIS fIGURE.
• Determining Right or Left Hand Reducer
To determine a right hand or left hand HYTROL Reducer, look into the output
shaft with the input shaft on the high side. If the input is on the right side, it is
a right hand reducer. If it is on the left, it is a left hand reducer. (See figure
4B).
MAINTENANCE
The HYTROL Speed Reducer, if properly used, should require little
maintenance except for scheduled lubrication. Instructions for changing oil
and recommended lubricants are as follows.
• Lubrication
nitial Oil Change-drain the oil in a new Speed Reducer after approximately
I
A complete parts list is provided with
500 hours of operation and refill with recommended oil from lubrication chart
(figure 5B).
Regular Oil Change-After initial change, in normal conditions, the oil should
be changed every 2500 hours of operation, or every 6 months, whichever is
first.
To Refill-determine position of Reducer from figure 5A and refill with
amount of oil shown in capacity chart (figure 5C).
Grease Fittings-The Hytrol 5A and 5AC Reducers have grease fittings to
lubricate the input shaft bearing if they are not positioned to be adequately
lubricated by oil splash. (See figure 5A, Positions A, E, and f). Periodically
lubricate these bearings with a good grade of NLGI-No. 2 Lithium Base EP
Grease, applying only a very small amount each time.
• Installation Instructions for Vent Plug
1. determine position of reducer after equipment has been installed. (See
figure 5A).
2. Remove solid pipe plugs & install vent plug & grease fitting(s) in position
indicated by drawings. (Other positions may cause leakage).
3. On the Model 5A only. Remove small pipe plugs and add two grease
fittings (item 2) as indicated in position "A", and one as indicated in position
"E" or "f".
4. If reducer is mounted in position "C" or "d", remove oil level plug & insure
that oil is up to this hole. If not, add oil until it comes up to this level (approx.
1/4 qt in the 4A, 1/2 qt in the 5A). To add oil, remove pipe plug or vent at the
uppermost part.
5. Position "f" not recommended-premature oil leakage may occur around
input shaft seal. Use this position only if no other will work.
• Removal & Installation
If the speed reducer is removed from the conveyor for maintenance purposes,
the following precautions should be taken upon reinstalling the reducer:
1. When the reducer is used in conjunction with sheaves and sprockets,
care should be taken to insure that shafts are parallel and sheaves and/or
sprockets are in alignment. This will prevent damage to bearings, chain and
sprockets, sheaves and V-Belts.
2. Sheaves and sprockets should be properly keyed and tightened to the
shafts to prevent wear to the shaft and bores. Extreme belt or chain tension
should be avoided.
3. When assembling sheaves or sprockets on reducer shafts, they should be
installed as close to the reducer housing as possible. Sheaves or sprockets
should not be driven onto the shaft. This could result in damage to bearings
and/or reducer housing.
• "C" Face Motors
Models 4AC and 5AC speed reducers are supplied with a "C-face" adapter
and are coupled directly to the motor by coupling gears and sleeve. To
replace the coupling, refer to figure 5d and follow the instructions listed
below.
1. Install 3/4" bore coupling gear to reducer shaft using 3/16" x 1" long shaft
key. Tighten set screws through hole in "C-face" adapter.
2. Install coupling gear to motor (refer to chart for correct bore size). Locate
2-1/32" from face of motor using 3/16" x 1" long shaft key. Tighten set
screws.
3. Place sleeve onto coupling gear on motor and ease motor into place (look
through hole in "C-face" adapter to see that sleeve seats onto coupling gear of
reducer).
4. Align motor mounting holes to "C-face" adapter and install mounting bolts.
5. "C" - face adapters use a plastic coupling to connect the motor shaft to the
reducer input shaft. A gear is mounted to the end of each shaft. The gears nest
inside the plastic coupling.
It is important for these gears to be properly spaced on the shafts. Incorrect gear
setting can result in excessive coupling noise and bearing failure.
The Hytrol Motor Coupler Gage should be used to space coupling gears
whenever the motor or reducer is changed out. The Motor Coupler Gage is a
plastic template that mounts over the motor flange or the reducer adapter. This
gage will accurately locate both gears to their correct setting on the shaft. The
illustration on the face of the gage shows how to use it.
