Holt 2 Ton Differences

I’m working on a Holt T35 and ended up finding another for parts. The first is S25145 and the other is S25167. The later of the two has two brake pedals and the first only has one pedal that actuates both the left and right side at the same time. Given the fact that these are only 22 numbers apart, It’s interesting the substantial differences. Does anyone have any idea when or what number they went to two separate pedals?

I’m also looking for a recommendation for a place to re pour the Babbitt rod bearings.

Thanks for any information or advice!

This machine also has nearly new condition tracks. I know they’re not what would have came on it originally but they are nice!

I would love to find a parts catalog for that series 2-Ton. Everyone I see i pictures of is a little different.

I have a parts book that’s for the 25000 series 2 tons but it’s not nearly as helpful as the later caterpillar parts books. It’s more of a parts list with pictures but doesn’t show what changed at certain numbers.

I stand to be corrected but, I think I heard, that some early units had the steer brakes operated via the tiller bar mechanism and the brake pedal you have is not for steering but just a foot brake--my 25000 S/No parts book shows one foot brake pedal and one clutch pedal so it could be that you have found the change over point--

I believe that there was a write up in the ACMOC Mag. on the T35 (2Ton) story back in around 2004-6 if any one has a copy as it does not seem to be in the Library it may have some insight into your dilemma.

I have some very crinkled distorted page photos of the said pages on my phone but, it is almost impossible to read, given me by a Chapter 19 member who has a very early T35 in green with the round side windows in the engine crankcase.

If he reads this he may comment???
