8.0 MAINTENANCE
In order to the maximum life of the Saddle machine, the maintenance should be performed by an authorized Mathey Dearman
Certified Repair Center. The Mathey Dearman Saddle Machines require only minimal maintenance. In order to achieve proper
results, make sure the Saddle machine is handled with reasonable care and it is kept clean and lubricated. The machine should
be stored in a protective container such as a Mathey Dearman Machine Storage Box or the original factory shipping crate during
transporting or when not in use.
The Ring Gear, Pinion Gears, and Drive Chains should be kept clear of slag and other trapped abrasives, especially sand and dirt.
The Saddle, Ring Gear, and Cap Ring should be cleaned weekly and the Ring Gear track surfaces should be coated with
Lubriplate 130-AA or equal lubricant weekly under heavy use and before storing. The Drive Chains and Sprockets should be
cleaned regularly and coated with a film of a light oil or lubricant such as WD-40 or equal. The bearings (Figure 5 item 6) in the
Single Bearing Brackets (Figure 5) and the bearings (Figure 6 item 6) in the Double Bearing Bracket (Figure 6) are sealed
lubricated bearings and should never require replacement.
There is 1 thread hole in the side of the Single Bearing Bracket (Figure 5 item 1) containing a set screw (Figure 5 item 8) and 2
thread holes in the side of the Double Bearing Bracket (Figure 6 item 1) containing a set screw (Figure 6 item 10). These
Setscrews should never be loosened or removed except to replace the bearings (Figure 5 item 6) and (Figure 6 item 6).
Contact Mathey Dearman at 918-447-1288, should any questions arise that are not covered in the manual
8.1 Timing the Ring Gear to the Pinion Gears
Adjusting of the timing requires the purchase of the new Axle (Figure 5 item 3).
Note: Redrilling of the old Axle will severely weaken the axle.
8.1.1
Remove both Tie Rod Handles (Figure 4 item 7) from the Single and Double Bearing Bracket Assemblies (Figure 4
items 4, 5 & 6) by removing Hex Head Cap Screws (Figure 4 item 11), Washers (Figure 4 item 12), and Nuts (Figure 4
item 18) using a 9/16" wrench.
NOTE: Save Hex Head Cap Screws (Figure 4 item 11), Washers (Figure 4 item 12), and Nuts (Figure 4 item 18)
8.1.2
Remove 3/8-16 x 7/8” Hex Head Cap Screws (Figure 4 item 10) and 3/8” Washer (Figure 4 item 12) from the Left
Single Bearing Bracket (Figure 4 item 4) with a 9/16” wrench.
NOTE: Do not loosen the 3/8”-16 x 7/8" Hex Head Cap Screws (Figure 4 Items 10) hold the Right Single Bearing
Bracket (Figure 4 item 5) and Double Bearing Bracket Assembly (Figure 4 item 6) to the Saddle (Figure 4 item 1).
8.1.3
Remove the Drive Chain (Figure 4 item 15) from the Sprocket (Figure 5 item 2) of the Left Single Bearing Bracket
Assembly (Figure 4 item 4).
8.1.4
Place the Left Single Bearing Bracket Assembly (Figure 4 item 4) in a vise.
8.1.5
With a 5/32” / 4mm diameter drift punch, remove 3/16” x 1 ½” long Spring Pin (Figure 5 item 11) and 3/16” x 1” long
Spring Pin (Figure 5 item 10).
NOTE: Save 3/16” x 1 ½” long Spring Pin (Figure 5 item 11) and 3/16” x 1” long Spring Pin (Figure 5 item 10) for reuse
at a later time.
8.1.6
With a 5/32” Allen wrench loosen the Socket Set Screw (Figure 5 item 7) in the Sprocket (Figure 5 item 2) of the Single
Bearing Bracket Assembly (Figure 5).
8.1.7
Remove the Sprocket (Figure 5 item 2) from the Axle (Figure 5 item 3) of the Single Bearing Bracket Assembly (Figure
5).
8.1.8
With a 1/4" / 6mm drift punch, drive the Axle (Figure 5 item 3) / Pinion Gear (Figure 5 item 4) assembly out of the Left
Single Bearing Bracket Assembly (Figure 4 item 4).
7.1.9
With a 1/4" / 6mm drift punch, drive Axle (Figure 5 item 3) out of Pinion Gear (Figure 5 item 4).
8.1.10 Press the new Axle (Figure 5 item 3) into Pinion Gear (Figure 5 item 4).
Note: Redrilling of the old Axle will severely weaken the axle
8.1.11 Using the existing hole in the Pinion Gear (Figure 5 item 4) as a guide, drill a 3/16” / 4.7 mm hole completely through
the Axle (Figure 5 item 3).
8.1.12 Install the 3/16” x 1” long Spring Pin (Figure 5 item 10) in the 3/16” / 4.7mm hole.
8.1.13 Install the Axle (Figure 5 item 3) / Pinion Gear (Figure 5 item 4) assembly into the Left Single Bearing Bracket Assembly
(Figure 4 item 4).
8.1.14 Place the Sprocket (Figure 5 item 2) on the Axle (Figure 5 item 3) with the hub of the Sprocket facing outward.
8.1.15 Place the Drive Chain (Figure 4 item 15) on the Sprocket (Figure 5 item 2) of the Left Single Bearing Bracket Assembly
(Figure 4 item 4) and the Double Sprocket (Figure 6 item 4) of the Double Bearing Bracket Assembly (Figure 4 item 6).
8.1.16 When placing the Left Single Bearing Bracket Assembly (Figure 4 item 4) in position, rotate the Pinion Gear (Figure 5
item 4) so teeth mesh in the teeth of Ring Gear (Figure 4 item 3).
8.1.17 Install the 3/8-16 x 7/8” Hex Head Cap Screws (Figure 4 item 10) and 3/8” Washer (Figure 4 item 12) through the Left
