LT230 Lubrication Mods

Is yours a 1:1? The gear for the 1:1 's are the only one you can't buy cross drilled, all other ratio's you can.

Nope, 1.4 high range. From this link on Ashcrofts site:

Ashcroft Transmissions - Input gear

it appears it is not ratio dependant, but year of build. The case I have is an early LT230T (suffix B ) case, so the input gear is not available cross drilled. (As I read it)

True, but 1:1 (1:1003) which is a 14D or 26D fits in the A/B category that's why I asked, so all 1:1 ratio transfer cases you can not get the cross drilled gear for, therefore having to drill your own. Trust me, I found out the hard way:(

Vern, not sure if im not understanding you correctly, but the Suffix is the last letter in the serial number on the t/case. The first 2 numbers and very next letter are the designation for what vehicle and ratio it was fitted with from the factory.

So any ratio that is in an A or B suffix case(serial number ending in either A or B ) will not have an input gear that can be bought new cross drilled.

The reason I say this is because of your first statement saying any other ratio than 1.1 can be had in cross drilled. This is not entirely true and a little confusing.

The input gear basicaly only comes in 2 tooth counts, 26 or 28. But there are many variables to them that makes the ability to just use either in any case not so. As in the 1.4 ratio in my B suffix case, this imput gear is not available cross drilled.

So are you saying that either the 14D or 26D 1.003 ratios come in boxes with later suffix than B?

Sorry ignore that first post, I just re read what I typed, should have said all 1:1 ratio transcases you can't get a cross drilled gear for.

Vern, I just sent some emails back and forth with Dave Ashcroft. He is saying the 1.003 high range was also available in the "C" suffix boxes. These have a cross drilled input gear available. So the way I am understanding it at this stage, regarding the input gear, is, it is not dependant on ratio at all, but rather the build date/suffix.

This does not mean you can get the input gear for the 1.003 high range set that was used in a "C" suffix box and install it in a 1.003 "A" or "B" suffix box. You have to use compatable gear sets, as Bush65 pointed out in a couple of Isuzurovers threads:

Attachment 109093Attachment 109094i am about to do these oil mods to my lt230 and was wondering what the purpose of the flat machined onto the sleeve is for? And is it supposed to be fixed into a certain position on assembley or just spin around at it own accord?

Well guess thats in.the to hard basket! Will just do as instructed😊
