8000 SRM 707 Maintenance Procedures Every 1000 Hours or 6 Months
5. After the engine starts, operate engine at idle
speed for 5 minutes to make sure all air is re-
moved from fuel system.
DIFFERENTIAL AND DRIVE AXLE,
POWERSHIFT TRANSMISSION
The differential and drive axle use the same oil sup-
ply. The oil level must be even with the bottom of the
fill hole. The fill hole for checking the oil level is on
the front of the differential housing. Add oil shown
in the Maintenance Schedule. Install fill plug and
check for leaks.
VALVE CLEARANCE, CHECK AND
ADJUST
The 3.0L engine has hydraulic valve lifters and does
not require valve clearance adjustments during nor-
mal service. Check valve clearance on Mazda and
Perkins engines and make adjustments as needed.
NOTE: Additional information on the engines is in
the following sections:
• Mazda M4-2.0G and M4-2.2G Engines 600 SRM
496
• GM Engine 600 SRM 3 or 600 SRM 1020
• Perkins Diesel Engine 600 SRM 706
IGNITION SYSTEM
NOTE: The GM 3.0L gasoline engine has an elec-
tronic control module that controls the ignition tim-
ing. There are no adjustments.
There are no adjustments for the Perkins 704-26
(UB) diesel engine.
GM 3.0L LPG (IMPCO)
Check the timing as follows:
1. Disconnect initial timing connector. This connec-
tor is in the wiring harness (four-wire) between
the distributor and the ECM.
2. Run engine at 1200 rpm. Use a timing light to
check timing. The correct setting is 8 BTDC. If
the timing is not correct, loosen distributor and
rotate it until it is correct. Tighten clamp for
distributor.
3. Connect initial timing connector. Check timing
at idle speed. The timing is correct when it is
between 10 to 25 BTDC. The timing advances
as engine speed increases.
GM 3.0L LPG (Aisan)
To check the timing, perform the steps in the section
GM 3.0L LPG (IMPCO), but use the adjustment set-
tings listed below:
• LPG (Aisan Open Loop) = 8 BTDC at 800 ±25 rpm
• LPG (Aisan Closed Loop) = 8 BTDC at 800 ±25
rpm.
Mazda M4-2.0G and M4-2.2G
The Mazda M4-2.0G engine has an electronic igni-
tion system. See Figure 34. Change spark plugs and
check timing every 1000 hours. The correct spark
plug gap is 0.8 mm (0.031 in.).
