Hi all
Recommendations please… I need an oil transfer mini pump as I am doing a gearbox oil change… There are so many out there…
Also, I need a crush washer for the gearbox drain plug… Best place for one of these?
Thanks…
Personally speaking…
Lidl oil transfer pump for £15 works fine. Comes with all the hoses etc. Don’t over think it, get a cheapy you can through away and replace if it gets dirty as you don’t want to be pumping grit into the box.
Washers, get a kit of copper washers off ebay or amazon. Cost about a tenner for a lifetime supply.
I got a Silverline one off Amazon intended for outboards but did the job in no time at a cheap price.
The washers for the ND are ‘alloy’ not ‘copper’. Is there a reason? Does it matter?
I purchased from here Beal UK - Workshop Supplies & Automotive Consumables They were so cheap I got some of each, no idea why but now I can use my favourite saying------“it’s in stock”.

NC.
In my opinion it does matter whether you use copper or aluminium.
Alloy crush/seal washers for drain plug/refill. Alloy less torque to seal and thus you won’t over tighten. Copper (which will be a copper alloy) due to the material nature needs more torque to seal properly.

Also copper hardens with age and/or work.
It is only soft enough for some jobs after being annealed. Easy enough with a gas hob.
When I did my bike repairs fifty years ago we needed to anneal the solid copper head gaskets and oil-banjo washers for any hope of them being leak-proof. Crush washers are a step better, but if copper still marginal if used where the alloy ones should be.
