Help! Injector Pump bleed screw broke

[sambodean]

well, the title explains it. I was in the process of bleeding my perkins 4108, and the bleeder screw broke inside the "hydralic head locking screw" (I believe thats the technical term). Does anyone know the size of the locking screw, and vent screw that fits inside the locking screw? I check trans atlantic diesel and couldnt find anything. And on a side note, anyone willing to sell a perkins 4108 alternator bracket? thanks!

The 4.108 was used extensively in tractors and other equipment. Try some farm and truck companies for parts. I found a great deal on a water pump for my Westerbeke W58 (which is a Perkins 4.154 painted red) on eBay from a farm tractor shop in Iowa.

The HP injection pump, I think, is the same CAV DPA pump as on my little Westerbeke. The screw is not available separately as far as I was able to tell, including tractor shops, etc. I recall it is 10-32 thread, I got a allen head cap screw that size and cut it to length, then ground a notch in the lower threads to let fuel and air escape as the screw is backed out. Having an allen head allows a long wrench which is helpful in my installation.

A shop that rebuilds injector pumps would be your best bet. Depending on age, there's more than one pump used on the 4108.

I have several 4.108 injector pumps and I will check tomorrow.
There were different alternator brackets used.
Send me a photo and/or dimensions.

If it is the entire idle/anti-stall assembly, I will take it. I was thinking about ordering from the UK.
