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 local motor factors or agricultural engineers. Many good engineering and parts companies now also sell online and I find that most things are available with next day delivery. 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.

Hydraulic pumps, hoses and pipes

WARNING - before you attempt any hydraulic repairs yourself, watch this video

The thing that you generally need in a hurry 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

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.

Hydrauilc ram with broken eye

This is the sort of failure any plant owner dreads. The eye has broken off the end of the rod on this hydraulic ram.

Crane slew 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.

Ram with broken eye

This loader ram has bent and the eye has broken off.

Repaired loader ram

The loader ram has been repaired with a new rod, eye and bushes. Note the guard on the the grease nipple.

Plough ram

This ram has failed spectacularly with a bent rod and the end cap burst right open exposing the seals.

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. I find a lot of parts are available on EBay or online from suppliers. Replacement engines are now also widely available at very reasonable cost. See the list below for useful suppliers.

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.
