Wanner Pump Oiler Refurbishment

**Anorak Bob** · 13th October 2012, 09:14 PM

I found a Wanner 300-4 oiler on UK Ebay a week ago for an incredibly cheap 10 Pound ( there is a new Wanner oiler for a Myford on Ebay UK at present for 72 Pound ). Turned out to be the model required for my mill's ( and Greg Q's Hembrug's ) domed oil nipples. The seller advertised it as both used and unused.

Shop soiled may have been more appropriate. It had not been used but externally there were rust spots. Removal of the end cap revealed more rust. I put some oil in the thing and pumped it out. There was rust in the oil. The idea of rust laden oil in the 13's Reuil-Malmaison la precision Industrielle

vertical spindle bearings had no appeal and rather than sling the Wanner in the bin, I thought I would pull it apart. But how?

I initially thought that the pump assembly had been pressed together but for an expensive tool that should enable the replacement of the cup seal, it seemed unlikely. Close inspection with a loupe revealed a thread behind the pressed steel end cap. I removed the cap with an adjustable pin spanner. More rust. To remove the knurled brass nose and avoid crushing the brass tube, the lathe chuck proved the perfect answer. The knurled nose was tight.

There was an O ring at the end of the outer steel sleeve. It had become hard and inflexible. I struggled to remove it. Eventually its removal was achieved by skewering it with a point from one of my compass sets and prising it out with the aid of a small screwdriver. I'm hoping the O ring was not some special hard grade of rubber.

Most of the rust was removed mechanically with jeweller's files and 1200 wet and dry. There was rust in the pressed steel end cap which was difficult to access. I immersed the cap in Corrodip with good results.

The external bodywork was cleaned up with a wire wheel and re blued with Birchwood Casey "Super Blue" Liquid Gun Blue. It's pretty close to the original finish on the steel.

Hopefully I won't have any drama procuring a replacement O ring.

If all goes well, I will refit the domed nipples I removed from the mill and do away with the awkward to use pom pom oiler I've been stuggling with* for the past two years. Another hopefully!

Hi BT,
ummm isnt that a pom pom oiler? What am I missing?
There is a lot more going on in there than I would have thought.

You aren't missing anything Stu,

They go by a number of names. The seller called it a high pressure oil gun. Abnox, the Swiss manufacturer, call them hand push pumps, others call them telescopic oilers or pom-poms. Wouldn't matter what I called the thing, the interest will be limited to maybe a couple of owners of Euro machines and of course yourself.

Ummm and me Bob. My Dormac is covered in oil nipples.
If anyone is considering offloading a Pom Pom I would be interested.

You Phil, GQ and Stu. I have reached my target audience then.

Does the Dormac have the rounded nipples or the more conventional type?

BT

**Steamwhisperer** · 13th October 2012, 11:53 PM

Not sure of the shape Bob. I thought rounded but now I am not sure. I will have to check the pics.

**Steamwhisperer** · 14th October 2012, 12:02 AM

Yup, Rounded type

**Anorak Bob** · 14th October 2012, 01:54 AM

So Phil,

How have you been oiling them?

My Alemite pom pom oiler suits conventional nipples not the rounded type. Whilst some oil enters the rounded type a lot doesn't which led to my replacement of most of the round ones. But there is a problem. Some of the original fittings can't be replaced due to lack of clearance around the nipple. Hence my pursuit and acquisition of the Wanner and the intention of reverting to original nipples and assured lubrication.

It appears that oilers to suit rounded nipples aren't too common. Can you replace all your nipples with the standard type?

Bob.

I own an oiler very similar to that which I shall photo tomorrow. It has the wrong tip on it however, being suited to the shallow dish button oiler that the Deckel has in a couple of spots.

Hi Bob,
I haven't had the need to oil anything on her yet. I am still waiting for the electrician to wire it up

I even have a job set up ready to start work as a non too subtle hint as to the urgency required. (it's making no difference though)
I have a feeling I will have to make a head to suit the rounded type and install the head on a conventional oil can as like you I will have great difficulty replacing some of them.
Although it is not impossible to replace the nipples with more conventional ones it isn't something I can bring myself to do. I guess it is a legacy of my line of work. (I like to keep things original)

I would rather modify an existing oiler.

My Sajo has rounded oil nipples too. I'm using an oiler that I picked up on eBay (pom-pom type) but it leaks in two places. One leak is around the back so could probably be fixed with an o-ring (there is not one currently there) but the other leak is around the shaft. I suspect that it has been used enough that the shaft has worn a little so that the bush that should seal on the shaft has too much clearance.
I've bought a s/h Wanner grease gun and when I have some spare time (currently scheduled for late 2016) was going to convert it for oil use.
