Using pump sounds like sump? I am looking for less messy way to remove oil from headstock, where there are only a few inches clearance between the bottom of the headstock and the drip pan. The drain plug is in the bottom of the headstock.
Check some of the local auto parts stores for an enclosed oil drain pan. I recently had to replace the one I bought to change oil in my 45 KW standby generator. After finding out the hard way that the old one had split a seam and was leaking.
I'm a little late but here is what I posted on another forum.
There doesn't seem to be much information on changing the oil for a Clausing-Colchester Triumph Mark 1 lathe, so I thought I would post this. I finally got around to changing the oil in the gear box. The manual calls for Shell Tellus 27 oil which is a obsolete hydraulic oil slightly lower than ISO 32. Most cross references show Shell Tellus 32 which is ISO 32. I wanted to use Mobil oil (easier to get) so either DTE 24 Hydraulic oil or DTE Oil Light circulating oil. After researching this forever it seemed, I decided to go with the Light oil. I found a couple good postings on these that I believed in, plus confirmed it with Mobile’s descriptions. Though both descriptions appear to read the same a key sentence is “ rapid and complete separation from water and a high resistance to emulsification. “ Also it doesn’t suspend particles but lets them settle out.
The best I understand is if you have a pump & filter use Mobil’s number series (DTE24). If you have splash lubrication, use their name series.
Anyways, when I purchased the lathe I was told the oil was last changed in the 80’s. So I opened it up and had a couple of surprises.
Picture 2 just shows the gear box. The drain plug is hidden behind lead screw drive gear. I had to remove it and move the banjo to get to it. When you pull the plug have your bucket in place and be ready to put the 3/8” pipe on or you will have a big mess in your chip pan (picture 3).
You will get some mess. I just stuck a rag below the plug before pulling it. Before you remove the plug, have every thing ready and do a hot swap between the plug and pipe. If you fumble with the pipe just put your finger over the hole and try again.
One thing the picture doesn't show is I had a end cap on the pipe. That way you don't have to worry about aligning the bucket up until the hot swap is done. Pipe sealant on the threads is not required. Lathe should take 2 1/2 - 3 gallons if I remember correctly. You can't purchase this oil buy the gallon. Only in 5 gallon pails or drums. I highly recommend you pull the top and clean it out. Mine had a lot of crap in it and a broken roll pin. I was able to find a replacement pin at Tractor Supply, in stock. It is a long pin. I think 1/4" x 2-1/4". Use a anaerobic gasket maker to reseal the top.
They sell rubber drain lines for small engines that should work . I would get a 6" nipple and ball valve if it was my lathe . Yes the first time may be a little messy but the next will be a no dripper.
