LUBRICATION
• Every Tuthill blower is factory tested, oil drained, and shipped dry. The oil reservoir must be
filled to the proper level before operation.
• Each T650 and T950H is supplied with sufficient Tuthill PneuLube™ ISO 32 synthetic oil.
• Before filling the blower, refer to Figure 1. The lubrication capacities shown are for reference
only and are based on filling from dry condition. A sight glass should be used to determine oil
level.
• Always follow the Filling Procedure outlined below.
• Never mix oil types or grades in your Tuthill Truck Blower. This could cause gear and bearing
failure.
FILLING PROCEDURE
1. Remove fill plugs.
2. SLOWLY pour oil through fill until oil appears up to the center of the oil sight glass.
3. Verify oil level is at proper level in sight glasses.
4. Replace fill plugs.
CAUTION: Check sight glass to ensure that oil levels are correct before starting.
WARNING: NEVER ATTEMPT TO CHANGE OIL WHILE THE BLOWER IS IN OPERATION. Oil level must be checked
while the blower is not running and on a level surface.

Lubrication Capacities
PREVENTATIVE MAINTENANCE
A newly installed blower should be checked frequently during the first month of operation, especially lubrication. Check oil level and
add oil as needed. Complete oil changes are recommended every 500 operating hours, or more frequently depending on the type
of oil and oil operating temperatures. The following is recommended as a minimum maintenance program. An oil analysis program
is recommended.
DAILY WEEKLY MONTHLY SEMI-ANNUALLY
1. Check and maintain
oil level, and add oil
as necessary.
2. Check air filter
restriction indicator
1. Clean air filter. Clogged air filters can
seriously affect the efficiency of the blower
and cause overheating and oil usage.
2. Check relief valve to assure it is operating
properly.
1. Inspect the entire
system for leaks.
2. Inspect condition
of oil and change if
necessary.
1. Inspect the drive line
bearings.
2. Change oil even if 500
operating hours has not
been reached.
KIT COMPONENTS
PRESSURE RELIEF VALVE
• The relief valve must be sized for the correct air flow and pressure rating. Install the valve as close to the blower as possible
and before the check valve.
• Ensure that pipe sealant is used on the threads to seal against air leakage.
AIR FILTER
• The filter should be selected to suit the air flow requirement of the application.
• Always fit an air filter restriction indicator set at 22” H
O (55 mBar).
2
CAUTION: An undersized air filter will cause the blower to operate at higher temperatures. This can cause blower
to overheat, causing damage.
6
CHECK VALVE
• Minimum restriction for application and mounted downstream of the relief valve.
• The check valve should be sized for maximum air flow (CFM).
SUCTION & DISCHARGE PIPING
• All piping should be free and clear of any welding slag or foreign material.
• The suction piping requirements is a minimum of 4’’ (100 mm) diameter for proper flow to the blower.
• The discharge piping is recommended to be 3” (80 mm) diameter.
CAUTION: Do not use a rubber elbow in the suction line during vacuum operation. The elbow will fail causing the
blower to overheat. This will cause damage to the blower.
MUFFLERS & DISCHARGE FILTRATION
• Minimum restriction for application
• Mount downstream of relief valve.
CAUTION: For food-grade applications, always install a properly sized food-grade discharge filter downstream of
the muffler (between muffler and trailer).
VACUUM VALVE
• A vacuum valve and filter must be installed to properly protect
the blower from overheating while vacuum loading.
• Size for proper air flow and vacuum rating.
• This valve should be located before the blower inlet air filter.
Normally this valve is mounted on the trailer.
DRIVE SHAFT ANGLE
PTO DRIVE SHAFT
• Blower drive shaft and PTO output shaft must be parallel and
in phase. Maintain axis within one degree in vertical plane to
ensure low vibration during operating conditions.
• Use a minimum of a 1300 series (SAE 1300 or DIN 100) drive
shaft that has been correctly balanced at the operating RPM.
• Do not force yokes onto the blower drive shaft or the PTO
output shaft.
• T650 drive shaft is 1 5/8” diameter with a 3/8” keyway and
2-9/16” inches long.
• T950H drive shaft is 40 mm diameter with a 12 mm keyway
and 65 mm long.
• Refer to Figure 2 to ensure that the drive shaft is at the
proper angle.
• A “U” bolt hanger (Figure 3) should be installed to prevent the
drive shaft from damaging the blower or PTO if the slip yoke
comes apart. The slip joint should be half compressed. This
will also stop the drive shaft from dropping to the ground, and
causing potential thrust damage to the blower.

applies only to Seller’s equipment, under use and service in accordance with Seller’s written instructions, recommendations
and ratings for installation, operating, maintenance and service of products, for a period as stated in the table below. Because
of varying conditions of installation and operation, all guarantees of performance are subject to plus or minus 5% variation.
(Non-standard materials are subject to a plus or minus 10% variation)
PRODUCT TYPE WARRANTY DURATION
New 18 months from date of shipment, or 12 months after initial startup date, whichever occurs first
Remanufactured 12 months from date of shipment, or 12 months after initial startup date, whichever occurs first
Repair 12 months from date of shipment, or remaining warranty period, whichever is greater
THIS WARRANTY EXTENDS ONLY TO BUYER AND/OR ORIGINAL END USER, AND IN NO EVENT SHALL THE
SELLER BE LIABLE FOR PROPERTY DAMAGE SUSTAINED BY A PERSON DESIGNATED BY THE LAW OF ANY
JURISDICTION AS A THIRD PARTY BENEFICIARY OF THIS WARRANTY OR ANY OTHER WARRANTY HELD TO
SURVIVE SELLER’S DISCLAIMER.
All accessories furnished by Seller but manufactured by others bear only that manufacturer’s standard warranty.
All claims for defective products, parts, or work under this warranty must be made in writing immediately upon discovery and,
in any event within one (1) year from date of shipment of the applicable item and all claims for defective work must be made
in writing immediately upon discovery and in any event within one (1) year from date of completion thereof by Seller. Unless
done with prior written consent of Seller, any repairs, alterations or disassembly of Seller’s equipment shall void warranty.
Installation and transportation costs are not included and defective items must be held for Seller’s inspection and returned to
Seller’s Ex-works point upon request.
THERE ARE NO WARRANTIES, EXPRESSED, IMPLIED OR STATUTORY WHICH EXTEND BEYOND THE DESCRIPTION
ON THE FACE HEREOF, INCLUDING WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY
AND FITNESS OF PURPOSE.
After Buyer’s submission of a claim as provided above and its approval, Seller shall at its option either repair or replace its
product, part, or work at the original Ex-works point of shipment, or refund an equitable portion of the purchase price.
The products and parts sold hereunder are not warranted for operation with erosive or corrosive material or those which may
lead to build up of material within the product supplied, nor those which are incompatible with the materials of construction.
The Buyer shall have no claim whatsoever and no product or part shall be deemed to be defective by reason of failure to
resist erosive or corrosive action nor for problems resulting from build-up of material within the unit nor for problems due to
incompatibility with the materials of construction.
Any improper use, operation beyond capacity, substitution of parts not approved by Seller, or any alteration or repair by others
in such manner as in Seller’s judgment affects the product materially and adversely shall void this warranty.
No employee or representative of Seller other than an Ofcer of the Company is authorized to change this warranty in any way
or grant any other warranty. Any such change by an Ofcer of the Company must be in writing.
The foregoing is Seller’s only obligation and Buyer’s only remedy for breach of warranty, and except for gross negligence,
willful misconduct and remedies permitted under the General Terms of Sale in the sections on CONTRACT PERFORMANCE,
INSPECTION AND ACCEPTANCE and the PATENTS Clause hereof, the foregoing is BUYER’S ONLY REMEDY
HEREUNDER BY WAY OF BREACH OF CONTRACT, TORT OR OTHERWISE, WITHOUT REGARD TO WHETHER ANY
DEFECT WAS DISCOVERED OR LATENT AT THE TIME OF DELIVERY OF THE PRODUCT OR WORK. In no event shall
Buyer be entitled to incidental or consequential damages. Any action for breach of this agreement must commence within one
(1) year after the cause of action has occurred.
