Performing a Royal Upgrade

Stan,

As I earlier said, you want to use SAE 10W30 grade motor oil. Since you have a 1976 model, there would be only one oil port (there will be a red cap), and that is by the rear wheels. When filling up the wick, make sure you do not overfill it.

Thanks. Do you think this oil is appropriate or can you recommend something better?

I recommend this and never detergent oil as detergent oil I understand ruins bronze bearings.

Oil

3 in 1 oil or 5 in 1 oil. This is what I have used.

 

[stanl]

Aren't 3 in 1 and 5 in 1 20 weight?

 

[lesinutah]

No

Here's a link. This is what I use and alot of people on the oiler royals.

@lesinutah - I'd be concerned that the 3-in-one on Amazon doesn't give a weight to the oil (like most multi-in-ones).
Heck, it's made by WD-40 which is even less encouraging.

 

[lesinutah]

Good grief

It's an sae 20 weight machine lubricant.
I have over 20 royals it doesn't ruin anything. Its what vacuum shop uses when servicing royals. You really think a thick ass 30w oil is any good. It's thick. And won't penetrate and lube everything g well.
If you don't believe then maybe you shouldn't ask advicevand when someone gives you sound advice you Question it because it's not a 30w oil. BTW it's #2 selling lubricant on Amazon. Do as you wish put that 30w and watch the bearing seize up because the oil won't break down.

I was just asking if the Ace Hardware oil I linked was acceptable.

If you want to argue about the weight, here's a thread: https://www.vacuumland.org/cgi-bin/TD/TD-VIEWTHREAD.cgi?6526

I suggest and question every answer. If you shoot down everyones advice don't ask.

Just the bulb...

Bringing this up again. The last T7 bulb I bought I ended up taping with electrical tape because it was loose and flickered.
It died recently, so I got some LED bulbs and they're loose too.

Anyway, researching T7 bulbs I found out that it means 1/8ths of an inch. So a T8 is 8/8 or 1-inch and T7 is 7/8s of an inch.

I'm wondering if the reason these are loose is because they bulbs should be bigger.

Anyone have any knowledge if the T7's were always proper? I know putting some drops of solder can also help, but I'm thinking a slightly larger bulb, like T8, might work better.

Of course it could also be too wide for the socket.

Buy

A sylvania 1155 bulb. There's nothing to cross reference just buy. Just buy the sylvania bulb not any of the off bulbs.

I'm adding a link to make it easier.

[stanl]

Wow. Thanks. That's nothing at all like what I thought they bulbs should be.
I was going with a standard T7, like this..

[stanl]

...I just went to order it and saw that it's 12v. I thought these vacs used 120-130v for those sockets.

 

[lesinutah]

You

Worrying about wattage when it's the oem bulb for the machine. I bet you just find something to complain about. That's the advice you get if u don't like it dint ask.

 

[stanl]

I'm sorry. Maybe I don't know anything about electronics, but doesn't pumping 10x the rated voltage into a light bulb make it blow out?

 

[lesinutah]

Its

The bulb royal recommended. There's no 120 watt bulbs you use for your house. 120 watts is about 1 of the 5 amps your vacuum is pushing. The bulb will I guarantee it will work. The bulbs are on 120 volt system but 12 volts. Royal , kirby eureka and rainbow came from the factory with the sylvania 1156 bulb. It's a side marker for a trailer. If you Question it then why is the light in your house in your room 60 watts or 20 watts your not running a Jacob's ladder it's a dual polarity sylvania 1156 bulb.
The motors run 120 watts per amp. If you got a 350 watt motor 120 watts aren't going to no light bulb unless that light bulb has a beater bar.
Like I said it's the stock original equipment manufacturer oem bulb.
If that doesn't suffice your noodle you need to go to the dr.

 

[stanl]

I'll give it a try.

It's just that I'm confused by what you're posting. You recommended the 1155 bulb, but linked the 1156 on Amazon. In your last post you do call it the 1156.

The 1156 is 26.88W and 12V (not Watts). That's what confuses me since the bulbs I've been using are 15W and 130V. Since electrical outlets are also approx 120V and they seem to work, a bulb rated for 12V seems like it couldn't handle it regardless of wattage.

Are you sure you don't mean this Sylvania?
