Question about 1993 MZ Country 500

Open Question

Has anyone replaced the crankshaft seals on a ETZ 250? What sort of job is it? Engine runs lumpy, electrics are spot-on but runs as if it has an air into crankcase issue.

How do i get the piston rod off the balance to replace the baren


The crank is a pressed assembly. A machine shop can do the job but it is best done at the Honda shop. The alignment of the crank halves is critical to how well the engine runs after the repair. tombones49.gif

I have a ford f-250 with 460 engine. 1983 model and have to replace the front crank seal. how much trouble is it?I already have the radiator off and replacing it.


You'll need to remove the crankshaft pulley and the harmonic balancer, which you'll need a harmonic balancer removal tool. The center bolt is usually on really tight. You can use a seal puller to remove the crankshaft seal from the timing cover.

This is most likely a leak from your rear main seal. It happens and can be a pain to replace if you're a DYI kinda person without the nec. equipment.
  1. Raise and safely support the vehicle with jackstands.
  2. Remove the transmission.
  3. If equipped with a manual transmission, remove the clutch and pressure plate.
  4. Remove the flywheel assembly.
  5. Using a suitable prytool, carefully pry the old seal out.
6. Inspect the crankshaft for nicks or burrs, correct as required.

To install:
  1. Clean the area and coat the seal with engine oil. Install the seal onto tool J-34686 for 3.4L engines, J 41349 for 3.8L engines or J 35621 for 5.7L engines.
  2. Install the tool (with the seal mounted to it) onto the rear of the crankshaft. Tighten the screws snugly to be sure the seal will be installed squarely over the crankshaft.

Yamaha DT 125 1986 - High Revs when idling


There have an air leak between the carb and the cylinder and/or the head and cylinder. Old hard / cracked rubber fittings and O rings are usually the problem. When extra air gets into the system it leans the fuel mix and the high idle is the result. It also means the engine runs hotter. Also, cracked or broken reeds can be a source.

warm up the engine and turn it off then try to turn the crankshaft pulley with a suitable wrench. if its too hard to turn by hand then the bearings might be too tight.
