early 1960's 520 gearbox oil fill question

early 1960's 520 gearbox oil fill question

PostBy: Normy On: Thu Dec 26, 2013 1:01 pm

Hi,

I did a search and found a bunch of different answers to the type and grade of oil to use in the gearbox.

1st, is there a pictorial of the area's that require the oil to be filled? I understand there is more than one location.

2nd, is it fair to say that the oil should be synthetic as the online manual says? Doesn't say grade/viscosity etc.

*. Where are the actual locations of the fill plugs & can they take the same oil?

*. I read in some of the comments the oil levels should be this or that, and using a wire as a dipstick works, but can you actually see the oil level and reference it to the height level from looking inside?

Pic's would be great if available!!

Sorry for all the questions, I have been running this 520 for 4 seasons or more and I keep a small board underneath the gearbox area to keep from dripping on the cement floor, which the board has been getting stained. I assume the oil levels are low and I would like to address this soon.

I can't say for sure that the gearbox assembly is from the early 60's, but the 520 is, it has the round porthole front door.

Thanks for any reply's

75w-90 or 80w-90 gear oil will work fine. Change the oil in the ratchet oil bath at the same time. I will try to get you some pictures later.

Thanks Rob,

I bought the Synthetic 75w-,

I'm trying to attach some pics of my gearbox etc, but I can't figure it out!

Thanks
Jon

I attached some pics of my gearbox and area. I can only find the one allen plug on top that happens to have oil on it. I noticed in the searching that I should have a brass vent plug, is this correct? Does this brass vent plug replace the allen plug on top?

With the other pics I attached, I can't seem to find any other area's to add oil. Am I missing something, somewhere.

Also looking at the gearbox on the far shot, what level of oil should it be at?

Thanks

Hi Rob, I'm not sure I have a ratchet oil bath? Can you look at my pics and see?

Thanks

You do not have the "old style" gearbox...yours is a unit that they started using sometime in the early 80's I think. That plug on the top is for adding oil, but the correct oil level is about halfway up the crankshaft that the stoker arm is connected to. You will need to use a piece of wire or something to stick down in the gearbox and check the level. 75w-90 gear oil is fine.

The oil pan under the main drum gear is supposed to have oil in it. I hate to ask how long it has been running the way it is...so I won't. Add enough oil to that pan so that about 3/8" worth of the drum gear is immersed in oil.

I just took this video to try and explain. I fumbled a few times, but this will give you the general idea. Ignore the information about the gearbox (yours is different), but note the other areas that need oil. I would also clean your stoker drum gear and oil pan with solvent before you put fresh oil in it.

Next time I will get a teleprompter. :roll:

Sounds fine to me, good job.
I use gear oil in the gearbox and 30 weight in the oil pan. Which reminds me, I have to change that oil.

Thanks Rob, I honestly can't seem to locate the oil pan under the main drum gear, is it visible in any of my pics or your excelent tutorial? I understand the gearbox, now that you confirmed it is a different style, should it still have a vent plug on top or not for this make?

Thanks

Thanks so much, is your oil pan and location to fill visible in your attached pic?

The plug on top of your gearbox with oil around it is the fill plug. It might be overfill already, which would explain the leak. Make a dipstick and see how much oil is in the gearbox.

You picture shows a pan under the ratchet assembly, it is held to the blower with two 1/4" bolts.

Yes, right under the drum gear. Will run down the cellar and get you another picture, will post it in a few minutes.

I must be as dumb as a bag of nails, I can't for the life of me see what your saying, I'll run down cellar and take a good look! :? :?
