D7E grouser re-bar

My books say 20 inches for the width sorry can't help with the rest. I have used 1/2 square bar welded on to build up the grousers,cheap and easy to get but not as nice as the proper shaped bar. Did the job when I was a very young lad during school holidays on our D2, none have fallen of yet and I could weld quite well by the time I had finished.
If you are doing the weld on trick remember it is important to have the earth clamp on the track plate you are welding on to minimise stray sparks that can ruin a bearing. Same goes for any welding on machinery keep the current path through the machine as short as possible. At your peril on modern gear with sensative electronics.
cheers WF

Base grouser shoe width is 20 in.
New grouser height 2.81 in, 100% worn @ 1.0 in (moderate service)
New plate thickness 0.59 in.

You can buy Proper Grouser bar for almost anything . Ring a track shop or ring Tilly's in Toowoomba Qld 07-46336000 . Not cheap I priced bar for a Cat 10 a while ago , Think it was about $7 a foot. . Want a good sized welder for Bigger bar , Probably run 6 or 8 guage LH 70 rods. Good luck LJ

Thank you for that info. I couldn't find the thickness any where on the web. Even at $7 a foot it would cost about $1300 which is a lot better than $5500 for new ones. there is a unimig welder where i work so i would use that. A bit under 300 feet of welding would equate to about 1 coil of wire & 1 bottle of argon. Can the bar be bent with a sledgehammer where the old plates are rounded(at the sides) or do i have to fill that gap with the welder?

Check out this web site, including instructions.....ends should be built up.

Hi Au7edd.
Wairyeratt, M8? Oz is a pretty big paddock. Quite a few companies that supply ground engaging tools, cutting edges, teeth, ripper boots, etc., also supply grouser bar stock. This comes in a bewildering range of shapes and sizes and you simply select the one that appears to most suit your needs, given your machine make and model, track equipment fitted and the existing wear of same. Given your estimated current grouser height of 35 mm, you're still over half of the original grouser height, which raises the question, is it really worth re-building them just yet? Unless you are doing a lot of heavy drawbar work or dozing in softer ground.

If you look up cutting edge and teeth suppliers near you or in your nearest city, wunna them ought to be able help you acquire what you need - - - for a 'small' fee, of course.

I live about 1/2-way between Brisbane and the Gold Coast and can give you contact details for a couple of suppliers around here if that is any help to you.

I welded up the grousers on my D6 a couple of years ago. The local track shop had 10' sticks of bar in various sizes. I pulled the track plates off to do mine so I bought a new track plate bolts too. (Otherwise I would have had to work in the cold on a dirt floor)
(12) 10' sticks grouser bar: $359
(280) bolts & nuts $299

My grousers were worn to a pretty good curve too so I clamped a guide to the plates and trimmed them straight with a torch. I mounted them to an engine stand to make it easy to position them for welding.
I (2)pass wire welded them using ER70S6 and haven't had any trouble with them. I did space the grouser off the plate about 1/16" as recommended in some of the literature I've read.

If after you think about what Deas said and you still want to build them up, you might want to look around for a track shop. They'll cut the your grousers down to about 1" which may eliminate the wear on the edges. Most shops weld both sides at the same time, off the tractor, single pass each side. They buy the grouser stock at a discount. Sometimes they pass that discount on which reduces your welding cost leaving you wondering if its better to hire them to do the job.
