    Idler adjustment Hi Pete! Well, today I got under the dude and checked out the gap on the inside guide plate, and it looked like it was running about 1/4" rather than the .020 required. Took a couple of shims out, and now it checks out at about .030 on each side, and the wobble is much...

    Idler Adjustment Thanks, Pete. I am a little concerned about the very thing you wrote about. I am using the P track (swamp track) and if I walk to the front of the track and place my feet on each side and shift my weight left and right, I get a lot of lateral wobble. Sometimes. At other...

    Guys, Need some help with the idler adjustment. I have a D21P-7 and have noticed some excess play at the front of the track. Looked in my manual for information on adjustment, and they say to remove shims from the guide plate to tighten the clearance between the guide plate and the track...

    Komatsu D21p-8

    Try for a D21P-7 I have had my D21P-7 with joystick controls for nine months now and have put a little over 200 hours on it. I would highly recommend this unit. It had about 2500 hours on it when I bought it. DO NOT buy a new one because of the cost, but know what you are looking for when...

    To Krackerjack9 about your Dozer. Whoa boy! No such thing as a "new D21-7". They are all D21-8's for the last two years or so. You are absolutely right in that new ones are way, way too much. I was quoted over $50,000 eight months ago on one. No way. You need to be looking at a mid-ninetys...

    Brake Adjustment solved. Well, success at last. With the joystick control (and possibly the model21 as well), when you shift the joystick to neutral the brakes are applied automatically. SO... to adjust the brakes the shifter has to be put in forward or reverse to unlock the brakes. Best not...

    Brake Adjustment I will try this with engine running. Heck, I'll try anything. My manual says to back off for "four rotations", but since I can't get any movement at all in either direction, I guess thats a moot point. It seems strange that the manual doesn't mention anything about special...

    Pete, These adjustment nuts wouldn't take heat, because they seem to be several inches long and go down into the brake area. I see no corrosion (sp?) at all. I think I am overlooking something here.

    Help! Brake adjustment for D21-7. Guys, Trying to adjust the brakes on my 1993 D21-7. Have done all the steps in the manual: removing rear panel, removing the two adjustment nut covers. THEN the problem starts! The manual says to "tighten adjustment nuts to torque of 4 kgm until the lining...

    To Rangerfreak about plates Are you talking about the access doors to the grease fittings or the entire covers? The access doors have one captive bolt which doesn't come all the way out, and just seem to spin. A screwdriver could be used to pry up the door once the bolt is backed off. Each...

    Safest Small Dozer

    A vote for Komatsu. Three months ago I purchased a Komatsu D21P-7 specifically for clearing small brush, young trees, fence lines, and other debris on my farm. I have just passed the 100 hour mark, and I must say I am completely satisfied with this little dude. If I had more experience as an...

    Tracks..Thanks. Thanks Pete and Ron. I have set the adjustment to 1 1/4" exactly according to the manual. I will check the heat on the front idler bearing just to verify that over tightening is not the problem. Probably the adjustment did cause a change in the sound which is what I am...

    Noisy under carriage Guys, I am getting a lot of squealing and grinding sounds from the undercarriage of my D21P-7. About twenty hours or so ago I tightened the tracks up to the specs as written in the manual. Within the last ten hours or so, my wife says that the tracks are making...

    Some old timers here! Hey Pete, What is it about two old guys in their sixties getting their first bulldozer? Like you, this is my first one, and I am using it for exactly the same thing you are using yours for. About that hesitation: Yep, I get it too, just about exactly as you...

    Seatbelts and clearing jungles. Hey Pete and all you other guys. Found an easy seat belt source. Go to: http://www.seatbeltsplus.com/ Mine was shipped today, and total cost was about $20.00. The D20-21-7 and I think the 6 series too, has mounting holes tapped on either side and to the...

    Some filter information. Guys, This is a little information about finding filters for the D20-D21 that I ran into with the local NAPA dealer. They have a good website online that cross-references filters, but the ones that kept showing up had no relation to what I needed on my D21P-7...

    To Pete and all the other guys. Pete, Don't listen to your brother. If I listened to mine, I would still be in bed sucking my thumb. There ain't nothing wrong with your dozer. Love the sweeps, but hey where did you get that seat with a headrest? Super. I am thinking about getting a...

    Kodiak Hey Lashlander, Well, back then we called it "Old Womans Bay", and the mountain to the left was called "Old Womans Mountain", for what reason, who knows and hey, who cares. I can locate the exact position of my old barracks in the picture you sent. If you look on the right side...
