Dozer Maintenance

Sorry Phil, the bullets went away when editing. Replaced with “Ordered List” function (5th from left in toolbar).

Any comments are welcome.  Phil

Dozer Maintenance Checklist

Every eight hours the following is done:

1. Check level of coolant. Daily at first startup.
2. Clean radiator screen and fins. Clean as required,inspect daily under extreme conditions.
3. Refuel. As required and prior to lay up.
4. Check engine oil level. Daily at first startup.
5. Grease track idler and rollers.
6. Eyeball track tension and track pin bolts.
    

Yearly the following is done:

1. Record hours in Dozer Maintenance Records. This is done every time maintenance or repairs are performed.
2. Clean air filter and change every 1000 hours. The element should be inspected daily when operating in extreme conditions due to close proximity of the cooling fan.
3. Change engine oil and filter and clean sump screen every 1000 hours or
   three years. Most four-stroke diesels have 250 hr. change intervals. I change mine by analysis and have no intention of dropping the sump until overhaul time.
4. Check gearbox oil level and change every 1000 hours. Or by analysis.
5. Check final drive oil levels and change every 1000 hours. Or by analysis.
6. Change fuel filter and clean prefilter element every 1000 hours or three
   years. I would inspect and clean the primary filter (including lift pump banjo-bolt screen) at the same time the secondary filter was changed.
7. Check hydraulic oil level and change filter every 1000 hours or three
   years. Or by analysis.
8. Check injector pump oil level every 250 hours and replace every 500 hours or three years.
9. Grease track tensioner.

Grease:

1. Fitting in front trunnion of swing frame equalizer. There should be a fitting on the rear trunnion but there isn't.
2. Water pump. No grease fitting on later models.
3. Clutch release bearing. One shot/100 hours while operating as track loader. N/A on shuttle shift models.
4. Blade pivot pin- top and bottom.
5. Cylinder pins.
6. Swing shaft.

Check tension on pulley belt ( ~5/8”).

Check and adjust track tension (3/4”). As required.

Check torque on sprocket bolts (? Foot pounds). See pic below.

Check for loose bolts. Always.

Adjust brakes using Bob's method.

Perform head bolt re-torque and valve clearance at first 50 hours and every 500 hours thereafter.

Check clutch using Leon's method. What is his method? Don't remember.

OK, my sump does not have that feature. By all means then clean it.

I don't think the E-series engines have that type of strainer.
