Changing oil in HT4..Hasting filter good enough?

[JAKEcatHT4]

My Cat dealer was too far away for such a low cost part so i did some cross referencing and come up with a hastings LF317. Found one locally for $8.75. Looks well made and came with three rubber rings. Now any recommendations on oil type for this old machine? It a 7U22836 SP. thanks

Can anyone instruct me to what size socket head plug that is on the bottom oil pan of the cat 315 engine i think. I crawled under there tonight to see what tool i will need from work tomorrow. Looks to be a 1" to 1 1/4" recessed plug. anyone?

It is not a specific size and actually is tapered. It's possible to make a tool using a bolt or Cat has the 1/2 in drive socket (tapered) to do the job.

OM, I though of grabbing some hex stock at work and using my big adjustable wrench on it. I guess I'll take a measure on it another day.. thanks

I made mine at the dealer to take the plugs out and I found a bolt near the size and ground the hex till it was the right size and then double nutted the bolt and it worked good for years that I used it.If you have a welder you can weld the nut on.Jake if you have some hex material that will work too and you could use a socket on it to turn it then.Probably need to trim a little off the hex that goes in the hex of the plug as they are cast and a little tapered it seems at the bottom of the hex in the plug.

I wouldn't hesitate to run a Hastings filter. As far as lube oil, I run Delo 400 15-40 in winter, and Delo 400 40 wt in summer.
