If you are having trouble convincing yourself that the swivel is the prolem.

Hook a tooth in one track and twoblock it try to make that track walk feel the hoses at the swivel heat up and listen to the oil rushing.

If the customer is really stubborn shoot the swivel with an ir gun and show them the heat.

Your bucket will reach the trackpad on one side of the machine and with a tooth hooked in the pad the track wont be able to spin when you try to move.

This will force the relief to blow for that side or the oil to bypass in the swivel.

If the swivel is bypassing the oil will heat up there in a few seconds.

You will also be able to hear the oil bypassing it will have a rushing sound.

I am 98% positive that your prolem is the swivel seals.

Heavey, I am 2% positive that the problem is the swivel seals, with your 98% between us I think we have things solid.
good stuff, tctractors

6000 hours seams to be where the swivel seals go the first time, then 3-5000 the next time. If you want the seal kit
to last longer we have been sending the swiveljoint out to the chrome shop. then you get another 10000 hours.

d4dozer, I am sad to think that you thought it was not a "Bit of Fun" without the need to read it the other 9 times, if you read my other postings you would have copped on sharpish??? I feel that Heavey Metal thought my post worth a smile.

tctractors - as I said I am a bit slow sometimes, I have read all the posts very closely because I would love to fix the problem first time! But what suddenly threw me was the 2% reference........

thanks for your help!

Well had another play with fixing it on the weekend. Used a temperature gun and both drive motors were about 65 degrees after a whole heap of tracking.

Found the places /ports to attach the gauges, but then found that they were 10 x 1.25 mm thread....it looks like they have never been of so I need to install a quick release to t fit the gauges. Checked that the pedals were getting full travel and tightened up the slack there.

Well finally......replaced the swivel joint and all is suddenly OK! After years of trying everything it was definitely the swivel joint so thanks for all the help. There must be a trick to not getting completely drenched in hydraulic oil though.

Hello Farm

Komatsu Perth was charging $5500 plus GST for a new swivel joint, I purchased one out of China for 300 USD plus 190 USD for air freight. We installed it in 5 hours, biggest problem was being covered in hydraulic oil, I am sure there is a trick to get rid of the oil first, but we missed it!

Hi,

I recently purchased an old PC 220-5 excavator. The old girl has 11000 hours on it and besides rust here and there appears in good condition.

All digging and swinging functions work well and have plenty of power.

The one small problem is the machine lacks power when walking / tracking. It feels like it is struggling - whilst the motor is revving fine, the tracks don't seem to have much power. It walks ok on 100% level surfaces, but the smallest incline sees it struggling. A friend who is an operator used it on the weekend (I did not mention the problem to him) and he said "its a great machine, but lacks a bit of power when walking", which says I an not imagining things.

When the tracks are lifted of the ground (by using bucket sideways) the tracks turn fine.

Both tracks and been checked and are not to tight, they were backed off slightly to be on looser side of the correct adjustment. I have checked the oil level in both track drives and they are fine. Tracks are in reasonable condition and all other oils have been checked.

The machine is still very usable, but I don't want to ruin it, or end up giving myself a huge repair bill by doing damage. So I was wondering
1) if I continue to use it is it likely that I can do further damage
2) what the likely issue is - hopefully something simple I can replace myself.

Thanks

I realize this is an old thread. I have a 200-6 with the same issue as the original poster. I’m not familiar with a swivel joint or where it’s even located? Is it common for the -6 to have this problem as well? Everything functions correctly otherwise. Use it daily 11,000~ hours
