It look like quite the process to split the motor, like a full tear down, but I’m willing to try. What other preventative maintenance do you recommend while I have the case open? The machine runs and shifts well. I plan to get an engine gasket kit, assuming one is available. It looks like I need a special tool to pull the flywheel, but just basic tools for the rest. What advice can you gurus offer?

I see two oil seals in that schematic. I will replace them both “while I’m in there”.

Thanks again. I’ll be reading the manual and shopping for parts.

Thank you! These are the kind of tidbits that make a forum like this such a wealth of knowledge. Greatly appreciated!

Copy that. Thanks for the wisdom! Regarding the front diff, I’m assuming I’ll only need to replace that female splined coupling (and seals, bearings, etc) if the R&P are good. Regarding the final drive shaft, is the oil seal you refer to the one through which the front final passes?

Hi folks, thanks in advance for reading. I have a 1995 400 Foreman and the front propeller shaft is worn to the point of failure. I’ve seen used ones available and I plan to replace the shaft & drive collar. My question is: how bad do the splines on the front differential and transmission output shafts look? They are definitely more worn at the contact surfaces than at the “shoulders”. In your experience, would you R&R the propeller shaft and ride? Or would you look to replace the front diff (coupling or entire unit)? What about the tranny shaft? I can provide more & better pictures if needed. Thanks for looking!

Thanks everyone for the welcoming greetings! I’ve been poking around the site and finding lots of helpful tidbits. This definitely seems like a positive and active forum! I’m glad to be a part of it.

Yes, older Honda ATV’s. ‘89 300 Fourtrax 2WD and a ‘95 400 Foreman. I enjoy wrenching on these simple and well-designed quads.

Well here’s a picture of our Mustang.

Howdy folks, new member here. I own two older machines, and I use them for work around the property and exploring the mountains. Cheers! -Jim
