antarmike Posted September 7, 2008 Share Posted September 7, 2008 Okay, the Antar is dead. Clutch plates are located (subject to confirmation) but the flywheel, Pressure plate, and intermediate plate will all need facing/ Metal spraying/ facing, but first I have to get to them. The choice was engine out or roll the gearbox back. In an Antar both are major jobs. I had the Engine out 4 years ago, and I know that it is far from easy, so I have decided to draw the gearbox backwards. This will mean taking out sections of the exhaust, big chunks of air braking, The lower half of one cross member, the first propshaft for a start. Sarted work today and attacked the air braking pipes, and valves. Also got one end of the exhaust free. But the Air-braking is a maze Quote Link to comment Share on other sites More sharing options...

antarmike Posted September 7, 2008 Author Share Posted September 7, 2008 As yet I can't reach an airpipe connection on top of the handbrake reaction valve. Naybe easier when the exhaust is out. Quote Link to comment Share on other sites More sharing options...
younggun Posted September 7, 2008 Share Posted September 7, 2008 (edited) thats more of a maze than the modern stuff ive found colour coded cable ties can help ones way through the maze this will be an interesting project to follow nick Edited February 23, 2009 by younggun Quote Link to comment Share on other sites More sharing options...

antarmike Posted September 7, 2008 Author Share Posted September 7, 2008 I am going to have to decide how to move the gearbox back. The Manual says take out batteries and seats, lift cab floor, build a gantry in the cab, resting on the chassis. Use a chain block on a travelling block, and roll the gearbox back. Plan b is a 3/4 ton capacity transmission jack Plan c is something welded to a trolley jack nose. Quote Link to comment Share on other sites More sharing options...
Stormin Posted September 7, 2008 Share Posted September 7, 2008 But the Air-braking is a maze I wasn't looking forward to plumbing the Air brakes up on the Ward but I feel a whole lot better now I've seen that!!! What a difference a few years makes to vehicle technology. Makes you wonder how they coped in the field in service. Surely a simpler system would have been better?

N.O.S. Posted September 7, 2008 Share Posted September 7, 2008 Euclid dumptruck job is similar but a fair bit smaller. Doors both open, gantry built straight through cab and Tirfor winch to take weight of box. If girder is packed to steady forward/aft movement, box can be pulled back without risk of gantry toppling and damaging cab. Why do they say pack the gantry off chassis rails I wonder? No doubt when on site, all is clear..... Quote Link to comment Share on other sites More sharing options...

You can tilt them if needed, when refitting through a twin plate clutch you do not want to be pushing and shoving as it is easy to damage a clutch plate, then you get drag :shake:. I used to use on on the 15 speed Fuller Roadrangers, made life easy. Recollect setting up a gantry in the cab of a Martian gun tractor once, to change a transfer box.

antarmike Posted September 9, 2008 Author Share Posted September 9, 2008 Sereious setback... The complete clutches I was chasing that Peter Court was supposed to have did exist until a month ago, when they were weighed in for scrap....I should have looked at the clutch earlier..... All the likely scrap yards deny any knowlwdge, and they say scrap is moving so fast they would be in India or China now... Quote Link to comment Share on other sites More sharing options...

Grasshopper Posted September 10, 2008 Share Posted September 10, 2008 Sorry to hear your tale of woe. I managaged to erect an engine hoist in the cab of my old bus bodied matador when i did the ckutch on it. I also know what a pain removing transmissions is, having recently done Mikes WLF transfer box. Loads of stuff was in the way and had to be removed.

Enigma Posted September 10, 2008 Share Posted September 10, 2008 I've got a lot of respect for people who tackle big vehicles like a Antar! I was annoyed enough to work on a Dodge clutch... Hope you'll get it sorted. Quote Link to comment Share on other sites More sharing options...

Mike, I work for a company which does metal spraying in Lincoln if you get really stuck. Chris Quote Link to comment Share on other sites More sharing options...
antarmike Posted September 12, 2008 Author Share Posted September 12, 2008 I have been warned of metal spraying. Someone I know had it done on a clutch, and metal became detached in service. In theory I can skim all the wear faces by a total thickness equal to the removable packers, and assemble the clutch without these packers and I will in effect be positioning the release bearing in exactly the same place. This of course only gives me one clutch life, instead of two, but it will be a lot cheaper. But Thanks for the offer. And I am sure not all metal sprayers do the same quality work, so maybe the poor sod who had the metal break away was just unlucky in which firm he chose.

I am sure not all metal sprayers do the same quality work, so maybe the poor sod who had the metal break away was just unlucky in which firm he chose. You're probably right there. I had some 85mm dia. excavator boom pins done (through a third party) - lasted just a few days. Re-done properly, they saw the machine out (8 years). Perhaps a case of not enough pre-heating, especially with big stuff? I'd always consider it as an option, but would need to know the firm knew what they were doing.

antarmike Posted October 18, 2008 Author Share Posted October 18, 2008 (edited) Some of the airbraking out of the way, inter-gearbox prop shaft out, and the lower half of the cross member taken out. This lower section has to come out to drop the propshaft. The gearbox will have to go back just over 12 inches. It can only do that if the output flange on the back of the gearbox is pulled from the output shaft. The flange is too big to go through the cutout in the cross member.

antarmike Posted October 18, 2008 Author Share Posted October 18, 2008 This propshaft is small compared to the one that runs from the Aux Box to the first bogey axle. Quote Link to comment Share on other sites More sharing options...
antarmike Posted October 18, 2008 Author Share Posted October 18, 2008 Trial offering up of High lift Pallet truck, to gearbox shows what has still to come out. The Cross member that carries the Exhaust support plate has to come out, and that means more air braking pipes have to go. Quote Link to comment Share on other sites More sharing options...
