Spares & repairs - links to useful sites for digger spares, hydraulic pumps, valves, hoses, engines, and other information are shown in the table at the bottom of the page
I find I can get general supplies for my digger, dumper and other projects such as hydraulic oil, grease, paint, nuts and bolts and hoses from the local agricultural engineers Christian Smith Agriculture. Because a lot of towable digger manufacturers went out of business years ago actual genuine replacement parts for many models are just not available. However, this needn't be a problem if you are a bit resourceful.
Basic Maintenance
The most important thing with any digger or item of plant is to check the oils and grease the machine daily. Low oil is the kiss of death for hydraulic pumps and engines alike and lack of grease will soon cause the bushes and pins to wear out. It's good to remember how many grease points your machine has so that when you are greasing it you can be sure that you haven't missed some tucked away grease nipple. Many grease guns come with a steel tube which are useless for accessing many grease points and it's best to change to a flexible variety. I also have a small Hilka grease gun which is handy for some jobs. Replace any blocked or seized up grease nipples and make sure the grease is actually getting to where it is needed.
Servicing
It is always worthwhile changing the oil and keeping oil, air and fuel filters changed at sensible intervals. The cost of this is nothing in comparison to expensive breakdowns caused by neglect.
Frame and Buckets
Most repairs to the actual frame, arm, buckets etc can be done using a basic tool kit, angle grinder and arc or MIG welder. Replacement pins and bushes can be made up by a precision engineer. Bits of plate for bucket repairs can be sourced from scrap, steel stockholders or fabricators off cuts. If you want to know more about repairing or building digger buckets click here
Hydraulic pumps, hoses and pipes
The thing that you generally need in a hurry (probably on a Sunday afternoon!) is a new hydraulic pipe. I get these from the local agricultural place too. The longest pipe on my digger burst near the end. When I got the replacement I also got the original shortened and a new end put on. That pipe now hangs up in the garage as a handy spare as all the pipes on the machine are the same diameter and fittings, just different lengths.
Kontak hydraulic control valves as fitted to the Fleming Micron. Even a simple machine like this requires 12 hydraulic hoses, top right hose is the low pressure return to the tank.
Powerfab with a Loncin engine to replace the Honda. Mart says "Loncin 6.5hp engine is exact replica". See links below to suppliers of the Loncin engine.
If you are unfortunate enough to have problems with your spool valves you are probably going to need a specialist hydraulic engineers to help such as Swift Hydraulics below. These parts can sometimes be refurbished or if not replaced with something similar. Pumps can also be replaced (see suppliers such as White House Products below). If you cannot get the exact hydraulic pump then a similar one can be used provided you can join it up to your engine and the flow rate/pressure is suitable.
Hydraulic Ram repairs
Ram seals are widely available and can be replaced without too much bother. However, leaks are often a sign of more serious problems such as rusted or pitted rods which tear the seals. It is not uncommon for eyes to break off hydraulic rams or for mishaps to occur where the rods get bent. There are specialist companies that can repair rams even when they are in a bad way. James from Clark Engineering kindly supplied the following interesting photos to show the sort of results that can be achieved.
Before and after picture of a standard hydraulic ram with a bent rod which was repaired by Clark Engineering
This is the sort of failure any plant owner dreads. The eye has broken off the end of the rod on this hydraulic ram.
This crane slew ram has been welded extensively in an attempt to cure leaks where the end cap is welded to the cylinder.
Here's the same ram after it has been repaired properly in Clarks workshop.
This loader ram has bent and the eye has broken off.
The loader ram has been repaired with a new rod, eye and bushes. Note the guard on the the grease nipple.
This ram has failed spectacularly with a bent rod and the end cap burst right open exposing the seals.
Here's the same ram after repair.
Many thanks to James for supplying these photographs.
Engine parts
Engine parts are going to depend on the make of machine you have. Honda and Petter parts seem to be reasonably easy to get. When ordering I am sure to go armed with all the engine and part numbers as you inevitably get asked for them! After many years of ordering parts (and wasted time) I usually try to take the old item with me just to be sure. Replacement engines are now widely available at very reasonable cost.
Workshop Manuals and Hydraulic Information
Workshop manuals for old plant can sometimes be sourced from Ebay or by putting a "wanted" advert in Classic Plant and Machinery magazine. This service is currently free to private advertisers. See http://www.cpmmag.co.uk/ for magazine details.
