    Always heat glow plugs prior to starting. 10 to 12 seconds seems to be the majic time at least on mine.

    Yikes, that's not going to grow back. Should be a factory recall and covered by warranty. Probably rusted from the inside out. Wholly cow man looks like some serious stretching, bending, pressing pounding, heating and some cursing thrown in for good measure to almost get it close enough to weld...

    Unfortunately The Bostrom Viking T bar seat was discontinued. However it has 4" of travel using a hydraulic cylinder (not an air cylinder), adjustable tension for any weight and three back tilt positions, slides forward and reverse, it weighs a ton, okay about 50+ pounds Sits higher than the...

    If you can fine one like this or similar you will be all set. Many pages ago in this forum, I posted pictures of this exact seat I installed on my D20A. Do not get the Armrest option, it is too wide to fit between the fuel and hydraulic tanks. Whatever you get best to have hydraulic suspension...

    Yep sounds about right. Its a fishing expedition getting that break actuator put back together properly. It is literally doing 4 things at the same time and you can barely see if its all together correctly. I wound up tying a string to the rod to fish it through and used a bore scope camera to...

    mcbike57, I was wondering what was happening with your steering system troubleshooting and repair. Sounds like your got that under control. Are the steering case covers back on? If so I was wondering if you have any tricks getting that control rod hooked into the front break band fingers while...

    Now its time to install and re-connect the hydraulic fluid heat ex-changer and hoses...... after that clean up the hood and paint the underside of that rust bucket. Its too darn cold to paint any more. It has been in the singe digits early in the mornings and teens in the afternoons. I will give...

    Radiator took a week - those guys took their sweet old time but did a great job, its as good as new. Got it reattached to the cowling, hooked up to the scissors lift then "drove" it over to the Dozer, lowered it down, then bolted it all up just like that (all by myself).

    While the Radiator was at the rad shop in Albuquerque, NM, the water pump was removed and replaced with a brand new one from Amazon. Amazing to get a brand new water pump off Amazon for a very reasonable price. The old one will get rebuilt sometime this summer for a spare or re-sale. A new 82*c...

    After removing the radiator from the cowling, the cowling was cleaned up, sanded, primed with Red Rust-Oleum, then Gray Primer then the finish coat. While the Alkyd Enamel was trying to cure, the radiator was taken to a local radiator shop to be rod-ed out, flushed, pressure tested then painted.

    Been kind of dead around here so here goes...... Hard to believe 12 years have passed since acquiring my hobby Dozer. This forum seems to be a good place to document and archive the maintenance history of my D20A-6. Perhaps also an inspiration to look for maintenance opportunities of your own...

    mcbike57, That is good news, both steering clutches are dis engaging . That leaves the issue to be neither steering break is catching. Got to tighten up those nuts under the caps in the back. I think you might have mentioned earlier that you tired tightening those nuts? (could be the threads...

    mcbike57 - soooo......... if you pull back both steering levers at the same time, does it keep going? without bogging? If so two problems 1.- neither steering break is engaging or gripping and 2. - neither steering clutch is disengaging. If you put it under a load, like drop the blade or up...

    Looks like quite an invested in a new set of tracks and sprockets, why not fix it all the way? Nothing like repairing it properly. Be prepared to install new bearings and a seal or two. Tracks and sockets will be off anyway why not go for it?

    Consider 1/4" or 5/16" threaded rod from a box store. Bend a hook at one end, then cut to correct length. If the hold down hardware on your D20 is like mine there is a ~ 3/4" angle iron the length of both batteries with holes on each end held down by long rods at a ~ 45* angle with a small hook.

    I know you didn't plant it that way. No disrespect or trying to be rude, Just trying to lighten up the situation a bit with some tong in cheek "humor" My apologies if in poor taste. I know the situation is not ideal. Your doing an amazing job under the circumstances and are to be commended...

    Hi Mike, (Jillmd), Nice tool you made to compress the clutch springs. I see your clutches are worn thin. Mine were not worn but rusted together in a bad way so I had trouble dis-engaging them as opposed to them slipping. Also both control shafts and needle bearings going through the steering...
