Hi Stace, why do you need a tool to fit the seal, I don't think I have replaced one of those, what makes it difficult?

Hi Norm the seal I have is very tight to push in ,because I think the seal to work thr spring side is up ,which makes it hard to press in with out damaging the seal.

Hi Stace and Norm,

It depends what 125 cc motor it is ,the early 125 cc the seal hits in from the outside but later 125 cc motors the seal hits in from the inside of the crank case so motor must be dismantled.

If the early 125 cc motor is not apart when installing the seal you would need a length of water pipe the right size to fit the seal and fit over the crankshaft, then hit the water pipe with a hammer to install the seal.

I use a socket from a socket set that is slightly smaller than the seal and hold the socket on the seal then hit the socket with a hammer to hit the seal in evenly when the motor is apart.

I wouldn't think a mower shop would charge much to fit a seal unless they need to dismantle the engine if it's the later 125.if you don't have the right tools.

Cheers
Max.

Hi Stace,
no problems if the spring is looking up as Max said as long as you have a socket close to the OD of the seal it should tap in easily

Hi Stace and Norm,

The problem may be that the 1/2 inch drive sockets are too small to fit the seal and you may not have a 3/4 drive
socket set to get a socket.

You could use an old mower blade plate hub if you have one or cut a round plate out of 1/4 inch steel ,if you can't find a
bit of metal cut a piece of wood to put on the seal then hit the wood with a hammer.

Cheers
Max.

Million ways to fit seals Max, just have to go carefully and keep the seal dead square as you tap it in
