Has anyone sourced the MEP803a generator end bearing?

[rvsuper8]

The manual says that the top cover and control panel all have to come out and the generator to be removed. But it would seem like the bell housing would come off through the access doors in the front. But I've been tapping on my bellhousing trying to get it off and it seems pretty stuck on there. My question is, does the generator have to be removed from the enclosure in order to replace the bearing. Seems the end bell housing below would slip out enough to just replace the bearing. But Im unable to tap the bell housing off. It has moved bout 1/8". But then it stopped.

It will come off they way you are doing it, but you're probably hung up on the bearing.
Try pulling or prying out on the end cover and then use a large socket and a hammer and whack the outer bearing race towards the radiator to try to get it out of the end cover.

OK Update. You were correct. It was hung up on the bearing. There were 2 keys to my success.
1. Remove the center support for the 2 access doors. This gave me access to the center of the generator.
2. Put some tension on the bell housing while simultaneously hitting the outside of the bearing with a rivet gun.

She slowly came out without damaging anything.
I can not get a bearing puller behind it. And my 2 jaw and 3 jaw wont take the bearing off even with some heat. So Ill get to cutting it off.
Thanks for all the advice. Ill report back my results to see if the sound was this bearing. Im still skeptical.
My local NAPA had the bearing in stock.

Success.
Had to cut the bearing out. Here are a couple of tips.
1. Remove the left access door
2. Unbolt the terminal board and move it aside
3. Remove the door hinge center section. It will take some doing and a bit of bending, but it will come out.
4. Remove the generator cover plate
5. Remove the bell housing nuts.
If the bell housing will not pull out leaving the bearing behind, put some straps and blocking on it as shown in the previous pics. Put some tension on the bell housing and tap the outer bearing towards the radiator. I used a hammer gun/pneumatic hammer judiciously.

On reinstalling, I heated the bearing to 275 and tapped her in. Cleaned the bell housing bearing receiver and it slid back on no problem.
Thanks for all the advice. The 'maybe sounds like a bearing sound' is gone.

Good job partner! I have been following the thread, but did not think to say:

1. Remove the left access door
2. Unbolt the terminal board and move it aside
3. Remove the door hinge center section. It will take some doing and a bit of bending, but it will come out.
4. Remove the generator cover plate
5. Remove the bell housing nuts.

You had enough help, and all of it was good. Good write up and pictures.

Cust brought a 803a over. Complained about a clacking sound. Only 75 hours on the meter.

People,

For the ten thousandth time. Do not trust or believe an hour meter.

It only takes a screw driver, pliers, and 2 minuets to change out!

Hello All! Can anyone weigh in to say if it is worth seeking out the bearing with metal seals vs the rubber ones?

 

[Guyfang]

I would call it a waste of time. Get what goes in the set. If it works, why fool with it?

@minke In this application, an RS bearing (rubber seals) is preferable, given the exposure to dust. I would stick with the factory bearing.

All the best,
