Engine Part ID

[Welderpaul]

I had a crack in the block on a Perkins 4203, the recommended repair was metal stitching, although I replaced the engine as that was cheaper.

Cast iron presumably?

What does this tap do. Water wee's out when i open it.
Its under the fuel filter. Can be seen on the shiny pic above too.

 

[madkayaker]

that's a water drain from the fuel bowl to stop water going into the cylinder resulting in a dead engine. treat it like a water trap on a compressor

 

[madkayaker]

its not what it thought it was its the coolant drain point for the block

 

[Wozzaaah]

It's called a tractor winkie, most agri spares places have them in stock but you have to ask at the counter.

Looks like it's the drain cock for the block. You let the water out in winter so it doesn't crack the block.

Yes, mine was cast iron.

Or rather you don't and end up with the crack Paul has to repair!!!!

Thats it really, is suppose it beats using a wire wheel on a grinder, plus it will get in the corners.
aluminium oxide best for cleaning paint/rust/grime off steel/cast iron/tin parts?

i have the 90cfm comp and pot using 6mm jet the grit is 075 to 1.5mm grit cos i can buy it cheap localy but to be honest it laces steel parts and is 2 corse superfine would be best or as said aluminium oxide

Can the media be reused if its collected? Might have a punt on one, i know they are not the best, but its only for light duty use

the aluminium oxide can be re used over and over expendable only about twice and is messy just sieve the dust out of it

I bought a professional syphon gun with a tungsten carbide nozzle to replace my Machine Mart one, it was about £50 from Anglo Scott Abrasives of Wigan. Worth every penny extra.

Looks exactly the same as the mm one. Is it the silver one you went for?

The MM I had was the SB4 http://www.machinemart.co.uk/shop/product/details/sb4-sandblast-kit-pick-up-hose

The one I got from Anglo Scott was the basic BHP12 gun, I provided my own pickup pipe and made a grit dispenser:-

The gun just feels a lot better than the MM one and the trigger valve is more positive. The MM one started leaking and the thread stripped the first time I changed the nozzle. The steel nozzles on the MM one wore very quickly.
