A Complete Guide For Diesel Hammer Installation, Testing & Daily Maintenance
By JiangSu Dongfang Architectural Machinery Limited, China
00:25
【Preparation and installation】
Hammer guiding channel parts
01:44
(Installing guiding channel)
03:39
After worker have fastening his safety belt, he shall climb up to the top of diesel hammer for tightening the guide slot nut and install cotter pins.
03:58
(Bottom parts as same as top)
05:00
Disassemble that nut for refueling
05:08
Filled up with premium diesel fuel about 35kg (35L, ≈ 9-10 gallons, with DD SAE 40 engine oil (DD5.3) for lubrication)
【side note: idk what "DD5.3" actual means, I've search for googles but there's only for diesel injector....so as said above was only my rough guess😂】
05:15
(After filled up diesels, tightening that refueling nut)
05:19
Add lubrication oil to the fuel pump daily
05:24
Add premium lubrication grease to the left and right guided rail daily
05:40
(Before further operations, safety rod must be firmly placed between hammer's head and base!!!!!!Otherwise serious injury or death may occur!!!!!!)
05:44
Cleaning piston before use
05:50
Pushing fuel pump for removing air bubble in the fuel line
05:55
Wipe out excess fuel off the piston thoroughly
06:06
(After all preparation were completed, remove safety rod and your hammer is ready for use)
06:55
Adjusting hammer throttle for different hammering speed
07:44
Hammer grabhook assembly (hook frame, hook, release lever, lever shaft and shaft spring)
07:58
(Workers now demonstrate how to assembling the hammer grabhook assembly)
08:20
Hammer release pulley assembly
08:23
(Workers now demonstrate how to maintenancing hammer)
08:36
This is triggering shaft
08:40
This is triggering shaft bearing
09:06
Add lubrication grease in that bearing hole every couple of days
09:26
When hammer not in use, please loosen that tank nut and draining out all the diesel fuel(fuel can be resed later)
09:36
(Again, before further maintenancing, safety rod must be firmly placed between hammer's head and base!!!!!!Otherwise serious injury or death may occur!!!!!!)
09:42
Remove diesel injector when you need to maintenance
09:49
Remove piston rings
12:11
Remove throttle assembly (eccentric shaft and throttle connecting rod) and fuel pump crank arm
12:33
Remove fuel pump assembly - loosen fuel pump capping nut
12:45
This is capping nut
12:55
This is fuel pump
13:08
Don't forget to take out that two copper washers
13:31
Remove hammer cap assembly
13:46
Remove hammer cap wrist pin
14:29
Remove hammer cap connecting pin
14:56
Remove fuel line below piston
15:05
Remove fuel line below hammer base
15:20
This is fuel line cored screws and copper washer
15:28
This is fuel line
15:45
This is fuel tank bottom module and nylon washer
15:53
This is hammer cap's connecting shaft, cap base and cap head.
16:00
(Workers now demonstrate how to assembling hammer)
16:50
Using box-end wrench to tightening cored screws
16:55
(From here, workers will demonstrate how to assembling fuel line, hammer cap wrist pin and connecting pin, fuel pump, throttle assemblies)
18:25
Stop pin must aligned with that locating hole on the eccentric shaft
18:33
Assembling piston rings
19:29
Pushing fuel pump for removing air in the fuel line
19:42
If you find an obvious signs on fuel dropping at the fuel injector, you need to tighten the capping nut and bolts again, or replace the entire fuel pump
19:54
If you find that piston have carbon build up when using diesel hammer, you need to stop using and clean it with diesel immediately. (Diesel hammer should be cleaned after every two shifts)
20:10
PLEASE WIPE OUT EXCESS FUEL OFF THE PISTON THOROUGHLY!!!
20:23
(Assembling and tightening fuel injector)
20:51
(And safety rod can be remove)
21:22
Please carefully check whether there is any oil leakage in the oil line before use
21:33
There you go :)
21:52
Thank you for watching XD
