Rebuilding the Engine! KZ750 LTD

Ok Question,

Im rebuilding a 1981 KZ750 LTD,

This is where im at, I need to replace the oil seals in the transmisstion cover. I have the cover all cleaned and ready to go. Now I hear that I need to put it in the oven and heat it up to What Temp? to get the old seals out and at the same time put the new ones in!

Your Thoughts?

Thank Johnny Red!

That's interesting,, where did you ever hear that you had to heat the case to replace the seal? Are the cases apart or still together?
The simplest way if they are still together is drill 2 small holes across from each other on the seal, drill just through the outer flat sheet metal then put a couple small sheet metal screws in the holes and pry the seal out. Replace by using a piece of pipe or a deep socket the same size as the outer circumferance of the seal, put some oil on the seal lip and the shaft and tap it back into the case straight.

This is the cover that goes over the shifter rod and such.

Ok Update!

I put it in the oven @ 300 degrees for 15 mins.

The old seals came right out. I then made sure it was clean and put the new ones in, they when right in, then took a peace of small wood and rubber hammer leveled the seals in there holes.

Now I have to just let them cool down.

haha this reminds me of a joke. "you know your a redneck when your wife tells you to take the engine out of the bathtub so she can take a bath":lol: :whistle:

This would be a "hot home made seal driver". Glad it worked. I would still use a good old cold seal driver to do the job.
