EC25-3PG seal replacement

donjetman · 01-30-2019, 06:55 PM

I think I'm working on a 1989 E-Z-GO with Robin 244cc, EC25-3PG

I'm trying to replace both crank case seals. I've got the engine out and clutch off, but need advice on how to get the opposite side fan hub off so I can replace the seal on that side too? I've got the cowling and fan off. Do I need a puller to get the fan hub off or what? Educate me please

Also, can somebody give me some links for all the manuals?
Thanks
Don

You need this, or something similar with a center bolt. https://www.amazon.com/dp/B01MS1KM0L...il_aax_0?psc=1

The flywheel holes are 6mmx1 threads. Put a socket over the end of the crankshaft, so you don't spread the ends apart.

This is more of an illustrated parts manual. It does show wiring, and the location of parts, but, it's not an actual maintenance manual.

Something happened with the upload. Let me try that again.

This should do it.

This thread has a link to an entire page of pdf files. They broke the manual down into sections. http://www.buggiesgonewild.com/gas-e...que-specs.html

If somebody ever got ambitious, they could download all of them, and put the manual back together for future users.

Thanks for the help.

I'll probably have more questions soon.

I have had my share of horrible experiences getting that flywheel off. Are you planning to use the oil injection again? If so, don’t damage the end of that crankshaft. I have always mixed the gas so I have a somewhat rough way of removing it…

It didn't have oil injection, so YES I cut the oil injection tabs off the end of the crank , center punched it, then was able to get the hub off with a puller.

Wow!!! what a mess!!! Thirty years of oil and dirt. And it was running when I started this project??? Unbelievable

On my first one I finally had to hang the engine by two metal bars screwed to the flywheel and beat the crankshaft until the engine fell on the grass. Not a good idea – I know – but it worked at the time!

I'm getting it cleaned up and have both new crankcase seals installed.
