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 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.

Volvo L220 Overhaul

May 30, 2012

We have been awarded the work to completely overhaul the engine and transmission on two of these massive machines.

Reassembly of the transmission using a new casing (there were cracks in the original) cleanliness and attention to detail are critical.

Volvo TD122 engine ready to fit. We have rebuilt it as a KLE version which is the low emissions permutation.

Following the engine and transmission refit, the rest of the machine will have a thorough inspection and repairs will be undertaken as necessary with the owners approval. When this one is finished it will be taken back to the quarry and the second machine will arrive at our workshops for similar treatment.

The International TD-24 Has Arrived

February 23, 2012

The beast is here!

International TD-24

This International TD-24 has come all the way from Sauk Centre, MN, USA. It was bought unseen (except photos) and the condition is not quite as good as was described by the seller. However, with a little bit of ‘elbow-grease’ we will soon have it ship-shape.

TD-24 Restoration

The engine is now starting and running well. We are removing the heavy front-end, the bulldozer hydraulic pump and returning it to agricultural spec.

TD-24 Sprocket

 We have major concerns with one of the tracks and are trying to find some new pins, bushes and a sprocket – maybe we will have to have some made, as most International parts are now obsolete. Anybody with parts or information leading to the purchase of parts will be most gratefully received.

TD-24 Paint work

The tractor will eventually have to be shot-blasted and repainted. Not much trouble was taken by a previous owner to prepare and paint, as the picture shows.

 

Keep looking for updates as we progress with the restoration – should be a very nice tractor when finished.

Workshop in Action: Caterpillar 980G Repair

August 25, 2010

This week we are attending to some faults on a Caterpillar 980G loading shovel.  The hitch bearings are badly worn and we have to ‘line-bore’ the trunion plates to accept our manufactured weld-in bushes.  When this is finished the replaceable bushes and bearings can be fitted.  All-in-all a time-consuming and expensive repair, this could have been avoided with a more diligent maintainance regime.

International BTD20 Crawler Restoration – Week 12

April 27, 2010

Another week where most of the work done isn’t well documented! But we hope you enjoy what we did manage to capture!

hamworthy hydraulic pump

Hamworthy hydraulic pump refitted after re-sealing and end-plates have been skimmed.

Sprocket assembly

Sprocket assembly all fitted and ready for track frame to be fastened on.

hole repairs

Tractor was retro-fitted with a different type of exhaust manifold and here we see repairs to the hole that was cut in the bonnet to take the replacement silencer.

bonnet repairs

A different type of steering oil reservoir had been fitted in the past and here we see repairs to the old ‘butchered’ bonnet hole (which had been badly cut octagonally with a chisel!)

final drive and sprocket assembly

All final drive and sprocket work completed and just awaiting track tension.

We’ll keep trying to document each stage of the restoration and will have more pictures next week!

International BTD20 Crawler Restoration – Week 8

March 23, 2010

Week 8 of the restoration and the BTD20 is starting to take shape. We think you’ll agree that we have done a very nice job with the gears and shafts!

BTD20 Gears and shafts

The gears and shafts are resting in their destination, but are still waiting the shimming-up process for pinion back-lash.

BTD20 Drive Sprocket Covers

Both drive sprocket covers have now been repaired after a struggle to remove them.

The restoration is coming together quickly now, and just in time for lovely spring weather! More to come next week!

Volvo A30 D Transmission Repair

March 10, 2010

Restoration is only a very small part of what we do! And as promised we are going to share some of the other projects we a currently working on…

This week we have been re-building an automatic transmission for Clifford Watts Ltd of East Yorkshire.

Truck being prepared for removal of transmission.

Volvo A30D Transmission Parts

Disassembled parts, some will be re-used as it was only the hydraulic retarder that was faulty.

Bare Casing

Bare casing ready for cleaning and assembly.

We will be bringing you more next week! If you want to find out more about our Workshop please visit our website.

International BTD20 Crawler Restoration – Week 2

February 9, 2010

Updates of how our International BTD20 crawler restoration is going, week 2…

Ok, ok we know technically we should now be on week 3 of the restoration, however as the workshop was so busy the previous week we didn’t even get chance to look at the BTD20! So if you can forgive us, we will call this week, week 2!

Bevel Gear Pinion Shaft

Main reason for transmission repair work is this bevel gear pinion shaft with damaged teeth. Probably due to low oil levels.

Steering Clutch

Preparing steering clutch for removal.

Oil seal

After a struggle, the clutch is removed in order to replace the oil seal, which is directly attributable to bevel gear damage.

Main Gearbox

Main gearbox is suprisingly free of wear or damage, not bad for 40yrs of service!

oil seal disassembled

The offending oil seal – took 8 hours of disassembly to get to it!

Hopefully next weeks restoration work will go ahead as normal! So please check back next week to see how we are getting on.
