1B. pull the spark plug lead. Leave the plug in the engine.
2.Disconnect the started circuit cable and the the throttle cable .
2b. remove the gas tank and the muffler . Also the oil filler .
3.Clean off the engine , fill will oil , look for oil pressure leak.
4. Find oil leak on bottom gasket.
5. Remove blade , blade guard ,drop the drive belt.
6, One more bolt holds engine release ( and support engine while undoing the bolt.)
7. lift engine free . Not very heavy . 6,5 hp Tecumseh weighs the same as bag of dog chow.
8. You now have just the engine to mount on the work bench.
9. clean it off with rags , remove all the lint.
10. remove the spark plus and look for soot. Replace.
11. Starting with the leaking gasket on the crank case side, undo the bolts , crisscross to maintain the torque.
12. The case cover might be stubborn, a rubber mallet tap will release it.
13. At this point take a rest . The motor is now crankcase up , I used a paint bucket to support it in place.
14. Gently pull the case off, try not to pry with metal , it will promote leaks later.
Lifting the case off you will feel inside, the oil slinger ( pump ) , it might fall out.
15. With the cover off place it on a clean towel or mat . Make sure that the oil pump is seated correctly back in its place ( there is a chamfered edge on the bottom, this is the oil way )
16.On the case cover make sure the two dowels are still there , they are steel dowels which are important . They can fall out . Set them aside.
17. Pulling sideways on the oil slinger will open any cracks .This is the part that needs to be repaired.
18. Clean out the oil in the case with gas or carb cleaner and mop it clean with lint free cloths. Inspect the crank and bearing and the valve lifters . Look for metal particles in the oil.!!!
19. Make sure that the timing tick and circle on the assembly for the crank / piston are aligned still .
20 .put some lint free cloth in the case and now scrape ( gently ) the old gasket away , remove the cloth and debris . Look for debris and move it .
21. Drop in the new oil pump ( slinger.) Get the nylon part flat side up. The channeled edge is down.
22. Using any engine re assembly oil make sure everything is oiled . Move the cylinder up and down and lube it too. Get the bearings . The re assembly oil will not harm the engine.
23. Replace the oil pump with the new and push in the dowels on the engine .Engine side. Put gasket in place .
24. Again check the timing marks as correct. New gasket installed .
25. Reaching under the case as you drop it on , make sure the oil slinger is in its dome( the round end. With your fingers arrange the gear so that the case drops on comfortably. Do not force it. It will click in.This is the fiddly bit and can take a few minutes of on and off until it works.
26. Replace the bolts , criss cross and tighten to the correct torque. Mine was ten inch pounds approx . I think.
27. Providing that you used enough reassembly oil , you can now turn the engine on its side and crank it via the nut on the starter side. IT should turn with little effort .
28. Remount the motor and fill with oil. Let it sit , look for leaks.
29. Crank it without the plug to make sure it does not seize.
30. Mount plug and start the machine , run it for a while and then look for leaks on the new gasket.
