t-case input gear question....

I have a brand new t-case input gear but it is the older one that is not cross drilled. Can I have it drilled by the local machine shop? WHat size hole is it and where is it located?

I was going to offer to snap a photo of my spare one, then I remembered that it is sealed up inside the case again.
I would suggest looking at the ashcroft site, they have some good pics of them.

you can also fit the oil thrower instead that is the cheap/easy way out and seems to work just fine. Basing that on the fact that the case I just fitted to my truck had one and the splines were perfect. there was a ton of oil back there when I pulled the cover off the first time, and since i forgot to reseal the pto cover before installing the case, the thing was puking out oil at a rather unbelievable rate. (since fixed)

You might be able to guess the size of the hole and see the location by looking at the picture on Ashcroft's website: http://ashcrofttransmissions.co.uk/part_28.html

4 holes. (2 all the way through). The gear is hardened so you need to grind a flat spot to get past that and then you can drill it yourself with a drill press.

I am guessing Rob Dassler would be your best bet for a thrower if you decide to go that route.

Id like to hear more about this "oil thrower" I have a very late build 95 but I have never pulled the input gear to check. Is this oil thrower something simple? It seems like the redesigned input came on late 97 LT-230's

I have a couple of the oiling plates sitting around if you need one. Good luck drilling the gear...I tried it once and only succeeded in ruining a couple of drillbits. I believe that the gears are hardened after machining....so even if you grind a nice spot to start drilling, you still have to drill through a hardened set of splines on the inside.

/Apparently/ the oil throwers bring up another problem... they lubricate the main shaft, yes, but stop oil from getting to the bearing at the end of the inspection plate.

I just went through this on my 109 LT77 LT230 conversion. Steve Parker have a thrower on their site and Ashcroft say they have them. Called Ashcroft and they said they no longer have any. However they had a rummage around and found one for about 15 quid. It was used. Jim is right, there are tales of the lack of oil to the end bearing. Some people suggest slightly overfilling the case. I guess only time will tell. The LR thrower I got from Ashcroft had two cut outs in it for the oil to get past the plate but can't say how much. Got great service from Ashcroft by the way.
Good luck

I've only ever drilled one gear....for my own heap. At the time I didn't consider the hardening as an issue and only ground the flat spot for a good spot to start the drill. I did 4 holes from the outside and I don't recall having a big issue getting through the splines. Then again that was 10+ yrs ago and at this point things I did last week are somewhat fuzzy.

I buy new gears now. Not a big fan of the oiling plate. Seems like a bandaid.

The gear is very hard but you can drill it in a standard drill press set up with a vise and the right drill bit. I've done a couple and I used a 1/4" diamond tipped drill bit which gives you just a little smaller hole than factory. When you come out thru the inner splines there is a chance you will break the bit so have a spare. I followed the same pattern as the factory drilled gear otherwise.
