    Need a new boom cylinder for an old machine: Insley 875

    My boom cylinder on the Insley has failed. I've repacked it without luck, I think it might be beyond repair. It's a 5 1/2" bore 48" stroke. I was thinking of trying a salvage yard, but it's been a while since I've had to find parts and haven't had any luck yet. Anybody have any info on new...

    Insley Excavator

    I might have skipped over those details, probably looking for info I needed at the time. Of course no telling what changes previous owners have done also. 50 years or more, most that are still operating have seen a lot! I've repacked a few hydraulic cylinders and most of them have been...

    Insley Excavator

    Could be... I can't quite tell from that picture. I don't know much about the later models. As I said in my earlier post, I haven't had any experience with Insley final drives. Don't know if they're good or not.

    Insley Excavator

    Not sure about that one. I have a 560B and a 875 and they have Detroits: 453, 471. Looks like a Detroit with a turbo. What's your ability and time to work on these? I've had to do work on various sections of mine, but haven't had to rebuild any engines. The 875 with the 471 was seized when I...

    JD 450 dozer towing

    Nope!! It just slid all the way. We did put some planks on the lowboy which helped as it pulled the boards with it, once off though, they never broke loose. I have a Case 850 dozer which didn't have any problems pulling it and we still had some snow and soft ground which helped. Just had to...

    JD 450 dozer towing

    Thanks for the replies. The owner said it's been sitting for about 3 years. I don't know if the tracks or stiff or not. I'm not familiar enough with JD's to know if the internals: final drive, clutches, and transmission will free wheel in neutral or not.

    JD 450 dozer towing

    Hi all, I found a JD 450 (straight) dozer around 1969, but not sure. The engine is blown, but the rest is i good shape and the price is right. The owner can lift it up to drive a trailer under it to load it. The rub is getting it off. I don't have enough equipment to lift it up, but I can...

    Insley H 560 B excavator

    560-B weighs in at about 31,000. As far as the tracks being free, yes and no. There are hydraulic actuators that disengage a "jaw gear" that will disconnect the drive transmission from the tracks, but the same action (different hydraulic ram) applies the brake to that track. If the brake band...

    Insley H 560 B excavator

    I have a 560-B, but I don't know what differences there are. I can look at my manual and see if it mentions anything. I know in the manual I have, there are some differences of B's depending on what serial # you have, different hydraulic pumps and configuration. Do you know anything about it...

    Caterpillar serial number/ year model

    Thanks, I'm not that familiar wit Cat. The dozer I am looking at has been taken apart. The seller didn't really know other than on the seat box there was a decal "D5B". The ID plate has been painted over a few times and hard to read. I could make out the 94J2238, and figured that number is...

    Why do vintage excavators have the boom on the left?

    True, I've seen a Hein/Werner H12D with push rods to the valve banks, and push/pull cables on Insley's. The cables would have to be even longer if it were on the other side. I changed an Insley 560B to push rods because the cables were very hard to move. It was easier and much cheaper than...

    Why do vintage excavators have the boom on the left?

    Speaking of Insley, I just resurrected an 875 from a local guy getting too old to work on them. Engine (Detroit 471) was seized, had to repack a cylinder, change a hose or two, scrape/wash 30 years of dirt and grease off, weld up the cracks I found and repin the tracks. Enlarged one of our...

    Caterpillar serial number/ year model

    Hi all, looking at at D5B s/n 94J2338 for sale near me. I've tried the SIS on the cat site and the new 2.0 SIS without success. I've tried this number plus a leading zero (94J02238) without luck. Also noted by Nige, Ironrecord not working. Looking for year and any other useful info. Thanks
