'74 Columbia

I killed this one once already a couple years back but just replaced the engine recently so now Im in the process of going over the rest of it so it can go back into service. Yesterday that involved pulling out the transaxle... it still works but the detent effect that keeps it in 3rd-4th is very weak so it can occasionally pop out of gear, keyways on the axle shafts are getting worn, and it leaks a bit past the axle shafts, so its been well used. I have a complete 960 plus a second 960 in pieces I can rob parts from(Thx Tyson)... havent really decided on which one will be the donor, maybe both. Once the Columbia is finished I'll see if there's enough good parts left for another tractor... but I kind of doubt there will be.

second pic - how I left it last night

Re: '74 Columbia

That is quite the subframe for your front plow or blower. Hope the trans goes in well.

Re: '74 Columbia

I didnt like that OEM blade setup so I reworked it a little. Should be a thread here on that somewhere but it was a few years back now. It works quite well, one of my better modifications

Re: '74 Columbia

I had a similar type front mount for the plow. It was hydraulic lift with a chain like that used on truck plows, so it floats. It worked well and I could pile snow almost 5ft because the tractor would ride up the bank as the blade pushed snow up. Your electric lift is a nice setup.

Re: '74 Columbia

You mean like this? LOL

same plow but I had it on this little JD while the Columbia was down.

Originally I was going to add hydraulic angle control aswell but never got to it, now Im not sure if I'll bother because I do most snow pushing with my Bronco II

Re: '74 Columbia

Yep, that's what it looked like. Surprised my doubting friends when I showed them what these GTs can do when set up right.

Re: '74 Columbia

I believe ya. LOL That pic with the JD is actually a small pile from last year, we didnt get alot of snow last year, in 2013 we had a huge storm and I had piles over 6' using the Columbia.

Havent taken the Columbia transaxle apart yet but I think I will have to go that route, I brought the complete parts tractor in and lifted it up to look at the axles/hubs... they dont look promising, hubs are rusted on to the axles which already look like they have been beaten on by somebody. So... looking thru the loose parts from the other 960(that trans was dismantled before I got it) I have what might be a usable differential with axles. keyways are not perfect but they are a whole lot better than what just came off the Columbia, if needed I'll add shims to tighten up the keystock.

Re: '74 Columbia

Inside of the Columbia transaxle has some rounded gears so Im gonna swap out the whole unit with one from a JD110, same Peerless trans but I'll need to swap over a few external parts. Added bonus is that the JD axles and hubs are splined instead of just having the keystock and slot.

Re: '74 Columbia

The 5 bolt hub is better too. Better selection of rims and tires.

Re: '74 Columbia

I think all the Columbia models had 5 bolt hubs.

Re: '74 Columbia

Yes, looking at several pictures on the web, all series with manual transmissions seem to have 5 bolt hubs.

Re: '74 Columbia

Hubs were stubborn to come off but after several days soaking in wd40 and alot of heat I eventually got them off without a single swing of a hammer.... now I need to switch over all the external bits from the original transaxle

Re: '74 Columbia

You have a large welding table. Nice for this type of dirty project.

Re: '74 Columbia

I like that table alot.... but the tough part, as you can see, is keeping it clean in-between welding projects. Lol
