Volvo / CAT Conversion

December 19, 2016

Back in October 2016, we were asked by one of our customers to quote for some engine rebuild parts to suit a TD73KCE engine in a Volvo A25C dump-truck over in Kenya. Upon closer inspection, he discovered that there were problems with the engine block, and decided that a repair would not be viable.

Unfortunately, we did not have any suitable replacement engines at that time. Our contact Piers decided to look for a more common lorry engine, or something similar, that he could source locally to replace his failed TD73. In the meantime, we continued to quote parts for elsewhere on the vehicle.

A few weeks later, an email arrived informing us that the TD73 had now been replaced, with a 225hp Caterpillar 3306DI no less. Piers described how “it was a mission to couple the Volvo PTO housing to the CAT”, but that this goal had been achieved.

Piers was understandably pleased with himself, and with the improved performance, “The CAT engine is 10.5 LTR and does not have to build the boost like the Volvo before it dishes out torque”. He acknowledges that the modification is not necessarily aesthetically pleasing, but has high hopes for a future conversion, saying “As you can see there is a bit of heath robinson engineering on it but I was not prepared to sink a load into it if I did not know if it would work. The next one will come out like it was factory!!”

Well, Piers, we look forward to seeing the next conversion.

Dump-truck Brake Calipers

February 8, 2016

We’ve had a bit of a run on brake caliper components in recent weeks.  Perhaps yours also need attention?

We currently offer refurbished calipers from stock, on a service exchange basis.  We also stock brand new pistons and seal kits if you’re servicing your own calipers.

Additionally, we have a small amount of used calipers that have been removed from a working truck, then checked and pressure tested. These cost less than the fully refurbished units, so may be useful if you’re replacing damaged calipers on a budget.

Contact parts@walker-plant.co.uk with your requirements.

Refurbishing

February 3, 2016

 

As well as attending to repairs and breakdowns, we also refurbish some of our larger components in-house.

Presently, we’re rebuilding a drop box for Volvo A25D / A30D dump-trucks.  Above you will see images of one unit undergoing refurbishment, and another unit we completed previously.

Notts NVTEC Tractor & Engine Working Weekend

August 28, 2013

A fantastic ‘Working Weekend’ was had at Babworth, near Retford courtesy of Joseph Camm Farms Ltd and organised by the Notts Group of the National Vintage Tractor & Engine Club. More land was made available and there was a good turn-out.

We did some repairs to this Ex military TD18 for a friend and brought it to the show to check it out – it went well, apart from a starting problem.

Working Weekend

Time for a well-earned rest with beer and ‘burgers!

John and Nick took 7 of their International Crawlers, 3 ploughs and a couple of cultivators. It was the first time they managed to get the two Ransomes ploughs to pull together properly. Although the tandem arrangement was designed for the International TD24, the soil was light enough for the BTD20 to pull it.

Many thanks to Robert Nicholls and Peacock & Binnington for their help getting a trailer full of ploughs to the event with this Mighty Massey, but we couldn’t let him go home without trying the ploughs.  Without weight transfer, the tyres just can’t get sufficient grip. This Massey 7624 had plenty of power but was beginning to loose traction, despite lots of front-end weight. However, he was able to keep going and put up a commendable performance.

TD24 Restoration – Completed

January 7, 2013

TD24 1The International TD24 restoration is now complete, save for the headlights which will be added in a few weeks time. Those of you who have been following this blog will remember that we have had a tormenting time repairing and manufacturing unavailable parts. The tractor was in a far worse condition than was expected. As you all know we bought the tractor from Sauk Centre MN, USA just over a year ago and we have worked on it nearly every day in some form or other (like lots of hours on the internet searching for parts etc.) It has been a labour of love and we’d like to think it shows, but it is doubtful we would ever take on another big tractor. John’s next birthday will be three score years and ten and he doesn’t relish chucking heavy parts around any more! So now is maybe the time to sit back and enjoy the collection, attending a few shows and working events. Following the pre-paint trials in August, we are now ready to go for the working weekend at Farnsfield on 28th and 29th December in aid of the local Air Ambulance.

TD24 We are privileged to have found this relatively rare tractor (series 241 195hp) for restoration and possess the facilities to rebuild it for its rightful role in preservation. We are always pleased to show its capabilities and demonstrate it’s ground-breaking design. Unfortunately the early TD24s fitted with bull-dozing attachments were less than reliable due to lack research and thorough testing. The TD24 was superseded by the TD25 which was much more acceptable and reliable, but by which time International’s respectable reputation was damaged beyond repair. The demise of the company followed within a few years.

International Harvester announced its revolutionary TD-24 crawler tractor in 1947. It weighed about 20 tons (with dozer blade) and was powered by a new 180hp 1091cubic inch (nearly 19 litres) 6-cylinder diesel. This new heavyweight of the earthmoving industry made headlines across the construction press as the world’s largest crawler tractor, clipping the title from the previous largest, the 163-hp Allis-Chalmers HD-19 (2 Tons heavier and 32 more horsepower than Caterpillar’s D8). The TD-24 soon earned an outstanding reputation as a heavy-duty bulldozer, and a perfect prime mover for pulling the largest scrapers.

The TD-24 was often teamed with Bucyrus-Erie’s largest scraper, the B-250. Bucyrus-Erie (now Bucyrus International) designed and built a line of tractor equipment for International tractors including dozer blades, rippers, winches and scrapers. Painted bright International red, the TD-24 scraper outfits made formidable earthmoving units and could be found in large fleets on many of the biggest earthmoving jobs of the 1950s. They became affectionately known as the “Big Red Teams.” The lion’s share of dozer work on the Alcan Power Project near Kitimat, British Columbia, was performed by International TD-24s working in some of the toughest conditions imaginable. Sponsored by the Aluminum Co. of Canada, this project was at that time the largest ever undertaken by private industry.

Now dwarfed by today’s monster crawlers, the TD-24 remained a leader for many years. The transmission and steering design was unique. The main transmission was a 4-speed syncromesh (for on-the-go shifting) and it had a separate forward and reverse unit for fast cycling in dozer work. There were also power-shifted 2-speed planetary gears in each track that made up the Planet Power Steering system. These planetary gears were controlled by the steering levers. Combining the high and low range of the planetary gears with the main transmission provided a total of 8 forward (and 8 reverse) speeds. Putting one track in high range and one in low caused a gentle turn with power to both tracks. For sharper turns the pivot brakes disconnected the inside track, as with a normal crawler. The TD-24 continued in production until 1959, by which time engine power had increased to 203 flywheel horsepower.

International TD24 Restoration Continues

August 2, 2012

The restoration of our International TD24 is coming along nicely. Having said that we have just found unexpected wear to the left final drive assembly – it has now been fixed. The front idler yoke on this side is getting the same treatment as the other side by cutting the slides and clamps off and welding new ones on. We expect to have track frame and tracks back on by the end of next week. Our work will then concentrate on minor repairs and cosmetics ready for blast cleaning and paint. All-in-all, it has been a challenging yet rewarding project. Hopefully the hard labour and financial cost will have been worth it.

This image shows just how difficult it was to remove the cap on the track frame pivot – we had to weld on nuts for larger extractor cap screws.

Bob Parkinson has undertaken a major repair to the top of the track frame.  A previous repairer decided to hack a couple of inches out of the strengthening brace and the track frame had taken on a twist which was one the reasons we couldn’t take out the front idler fork in one piece.

The last of the sheared off studs have been drilled and tapped out to take new over-size ones.

That’s all for now, but we will keep posting updates as the work progresses.

International TD9 Transformation

July 11, 2012

Our TD9 is now back from the paint shop and we think it has been an incredible transformation from the junk contender that it was.

Sitting proud with new decals.

Radiator cover and side panels fitted.

These hand grips may be a temporary measure. The Komatsu grips were the nearest we could find, brought over from America by good friend Paul Singer (who sold us our TD14a). If we can find the correct hand grips or have some made, they will be changed.

International TD24 Update

July 10, 2012

An update on the International TD24 restoration project.

Final drive assembled with new sprocket drive carrier and new sprocket, bearings and seals fitted. We waited a long time to discover the whereabouts of these (in USA) and the shipping costs were nearly as much as the parts! Unfortunately the rarity and the fact spares have long been obsolete is a stalling factor with this restoration. With scrap prices being extraordinarily high and demand for TD24 used parts being extremely low, all my contacts in the States have reluctantly let them go to make Chinese razor blades!

At last, we have found some serviceable track chains! These were discovered on the east coast of Italy, they might look a bit rough but the wear is minimal and will suffice for demonstration work.

Having removed the sump to investigate oil loss at the seal, we found that someone has not replaced the cotter pins on the big-end and main bearing cap nuts and we found that the leak was due to replacing the sump without a gasket.

The damage to both front idler shafts and bearings was so bad we decided to cheat a little and replace with home-made shaft and bushings.

Assembly now finished and ready to fit.

The idler yokes were also badly damaged and this image shows how we fabricated new ends to carry the shafts.

International TD9 Rescue

July 3, 2012

We were tempted to purchase this IH TD9 to save it from the scrap-man. We thought it was cheap at the time but there were a lot of parts missing with badly corroded and damaged tin-work. Here is the progress so far.

 

Not much left of the fenders!

Not much remains of the back-end, and the steering clutch department was almost empty!

This bonnet was typical of the condition of the body-work.

As we progressed through the transmission it was apparent quite a lot of damage was present.

The one remaining steering clutch was badly corroded and it took ages to dismantle, we managed to find new friction discs in the USA.

The brake drum and steel clutch discs have cleaned up quite well with blast cleaning.

 All that remains of the side panels – it was difficult to get an accurate template to manufacture new.

First fix. We assembled the new panels and diesel tank to be sure that they all mated together properly. Was then disassembled in readiness for painting.

Volvo L220 Overhaul Update

July 3, 2012

We had completed the bulk of the work on this shovel, when we undertook a large service before delivery.

An oil change from the rear differential revealed it was badly contaminated with steel and a test drive around the yard confirmed our suspicion that there was unacceptable wear.

We are refurbishing the unit to our customer’s instruction. Pictures show some of the wear.
