miter box shaft bearing

brmax · May 15, 2018, 04:32:44 PM

I would at least cover the lower third of the side shaft bearings. Or in another way I may fill oil up to the lower side of the shafts with the oil at full level. Or just enough to get the seal lubricated. Im not sure of your mounting of the box is it level. A photo would be a great addition here.

Good day

It is a 1985 model 10 and the box is the same as depicted for a 6v92 in my shop manual. It is level on the bracket. Here is a picture of the shop manual page. It does not show the separate vent. Mine has a threaded hole in the top of the casting with a vent and cap on it.

I have a couple of 6v miter boxes that have vents and a stick

Your box is not the same as my 1984, and it does not match your manual page. Part number 19 is the same dipstick/vent that I have on the top plate. The dipstick arrangement and the vent are different than anything I have (out of three). Eagle did some inconsistent things at times. I would still say that 4 3/4" below the top plate would be a good oil level.

Thats a nice gearbox. I personally think all these darn boxes needed a long hyd hose with the vent attached and all this secured a foot high, somehow.
I notice in your gearbox's last photo the piping for the dip-stick/fill tube. It seems where the small plug is at the lower T fitting, is where the oil level is required. I believe this level is close to the shafts half / center point and is also typical level on the MC-9 box.
Its an opinion and like shoes, most people have some

Good day

The City of Houston Eagles boxes with the 6v92 were all vented I have seen,I don't know if Houston did a a modification or what but they all have it sorta like the air intake deal on a City of Houston Eagle I guess.It should have a level plug to check the level with 3 qts is way to much,check around some boxes on the V8 had a bolt you removed on the shaft side flange for checking the level.
How much grease do you MCI guy use in your blower mitre box ?

Thanks Clifford,

That seems appropriate to me

That will put it about 1/4" from the dipstick bottom like Double Eagle posted earlier in the thread. When I get this done I will make a correction in my manual.

BTW these things are heavy. I had to call a friend to help me lift it out of the cradle.

, and I recommend gloves to avoid torn knuckles

The parts came from Luke this afternoon. It was a head scratcher to figure a way to remove the wear ring. They are on there really tight. I had to cut it as far as I could with a dremel wheel then chisel it off. I used a 1.5" galvanized pipe nipple to drive them on. The seals went in pretty easy. I used RTV to seal it all up and tomorrow will put oil in it to make sure it doesn't leak. After that I will reinstall the couplers and put it back into the coach.

I filled to one quart and indexed the stick about 1" above the end of the tip. I also transferred that level to the bearing seal and it seemed a bit low.

I added another 1/2qt and indexed the stick then transferred the measurement to the bearing seal and it is about 1/8" below the seal, so it won't leak. That should be sufficient. I will reinstall the beast this afternoon.

I also put a label to remember the amounts.
