felixx Posted July 28, 2014 Share Posted July 28, 2014 oh dude, awesome. i love how the exhaust serves mainly to bring the outlet from some distance away, to as close as possible to the driver its so the driver can put his sandwich wrapped in foil on it to warm up for smoko 1 Quote Link to comment Share on other sites More sharing options...
Valiant Posted October 6, 2014 Author Share Posted October 6, 2014 So back to this. Time to look at some hydraulics to get the blade moving. I had one original ram which was a basket case. It was good to have to help work out a size. With a bit of wheeling and dealing I've managed to get this lot together. Two Victor rams, one new one used but both the same size. One used 11cc per rpm hydraulic pump. A new control valve. And about 6m of good condition used hydraulic hose. The new rams have a shorter body than the old ones and slightly less stroke which has worked out well. The blade didn't come up very high by my calculations, so it would have been a prick to put onto a trailer etc. I've moved the mounts back and now it has plenty of travel up and down. This is where the carriage will sit with the blade on, on a level surface. The carriage and associated mounts have been fun in them selves, who ever made them wasn't worried about using all the steel and arc rods. 7 Quote Link to comment Share on other sites More sharing options...

Valiant Posted May 29, 2015 Author Share Posted May 29, 2015 Hi Craig. Yeah there has been a little. I've turned up a new bottom pulley with a 5pk drive so I can drive a hydraulic pump. I splashed out last week and brought a new Massey Ferguson TE20 radiator for it. It's a bit cold here today but hopefully this weekend I'll do a little more on it. Worthwhile update to follow at some stage. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Valiant Posted August 6, 2015 Author Popular Post Share Posted August 6, 2015 Back due to popular demand! I've been slowly spending time and money. New radiator purchased. Car ones just aren't the right shape and the little Honda ones are just too little. I measured up a friends Massey Ferguson TE20, it was spot on. I brought a new replacement one from the radiator shop. It will need it's inlet and outlets changed but that won't be a problem. Next up is a way to drive the hydraulic pump. I have a pump with a pulley, the pulley is a giant ugly thing as seen here. So I turned it down into a hub and redrilled a RB20 waterpump pulley to fit it. I don't know what the original pulley was mare out of, it was as hard as hell and took hours to turn down! To drive the pump it needs a pulley on the crank too, another RB20 gave up it's water pump pulley as did a Mazda b5. I turned up a hub to hold it all in the right place and a friend cut a key way in it for me. It's gone a bit rusty from sitting, nothing some scotchbright won't fix. Last of all. I had planned to drive this directly off the engine as the tractor has it's own gearbox. But. The more I have learned about them the more people I have come across saying they are too high geared standard with a motor that revs to 1800 ish rpm maximum. The common solution seems to be adapting a Ford Model T gearbox to them. I think that Datsun will rev to easily twice that of the original, I'm going to need an auxiliary gearbox. Luckily I have the Vanette box that came with the motor. It looks like it will be just about back to the start which is a bummer but hopefuly the result will be worth it. 12 Quote Link to comment Share on other sites More sharing options...
Popular Post Valiant Posted September 6, 2015 Author Popular Post Share Posted September 6, 2015 Here it is back at the start again. Motor has been out, clutch is fitted, van box back together and fitted to the motor. It looks like it will sit the engine about 100mm further forward which is good and bad. Good point is the air intake should be a lot simpler to make. Bad point is I'll have to cut the front out of the chassis and trim the sides to clear the bell housing and starter motor. Big thanks to CUL8R/Chris for finding me a Datsun drive shaft. I've dismantled the UJs and put the input yoke on the rear flange. The rear piece is a home made flange welded to the splined part of the original yoke. I turned it down and made the flange but was having too much fun to take photos. Until next time. 11 Quote Link to comment Share on other sites More sharing options...
Popular Post Valiant Posted September 13, 2015 Author Popular Post Share Posted September 13, 2015 I've spent a big weekend working on this. Work lent me a little gas set so I could notch my chassis to fit the motor further forward. One thing lead to another, I got a bit carried away with the torch and quite a lot got done. Rear mount for the gearbox. The sides of the chassis had been quite badly hacked about in the past. I also found out that these tended to crack their chassis around where they were notched from factory. I cut all the crap away, and welded some nice fresh steel in. Both sides are done but they look the same in a photo. Next up was to remount the motor. both sides look the same etc. Cut a couple of notches to fit the starter motor and bell housing And something I had been meaning to do for ages. Now the oil filter fits and is easy to change. Last of all some where to fit the radiator. I just about had to cut the front off the chassis which was a bit of a pity. The radiator is as wide as the outside edges of the chassis. It's too tall to sit on top of the chassis and fit the body work. Anyway after some cutting and a bit more welding it sits in there nicely. The side covers and grill will need a bit of a trim to fit. 17 Quote Link to comment Share on other sites More sharing options...

Valiant Posted September 15, 2015 Author Share Posted September 15, 2015 Thanks guys. I'm not %100 on the radiator notch. I think I'll cut it off again this weekend. Cheers Chris I might have to take up on that. Someone else on here should buy that Bristol, maybe some one with some land near Oxford? 1 Quote Link to comment Share on other sites More sharing options...

Borgweiser Posted September 15, 2015 Share Posted September 15, 2015 Nice dozer, train spotter notes; old motor in the thing was a rootes group unit- mk4 Minx or Humber 80 judging by the tall filter cartridge. 1 Quote Link to comment Share on other sites More sharing options...
Valiant Posted September 16, 2015 Author Share Posted September 16, 2015 Yes you're right, the old owner said it was a Hillman motor when I saw him recently. I would say it had been well melted down by now.. Quote Link to comment Share on other sites More sharing options...

Valiant Posted September 20, 2015 Author Share Posted September 20, 2015 The more I looked at this the less I liked it. I cut it back off and welded the old pieces back in. Then trimmed the top off. Made a couple of brackets up. Lined up the radiator with the hole in the bonnet, and away we went. I've remounted the alternator to the lower left, I think it's where a P/S or A/C pump might go on a car? Anyway it will give more room to mount a hydraulic pump up where the alternator was. The bottom hose has been altered to point into the front of the chassis, the radiator has had it's inlet and outlet changed to match the Datsun motor and I made a tensioner and dummied up a radiator hose. The alternator sits out a little but no problems. I've found a problem. The hydraulic pump I have, it's designed to rotate anticlockwise and I wanted to turn it in a clockwise direction. Aliexpress have pumps that look like they should do the trick, I'll order one this week. 5 Quote Link to comment Share on other sites More sharing options...
KKtrips Posted September 20, 2015 Share Posted September 20, 2015 turn the pump around and have it facing backwards? Â Like this but a pump. Â 1 Quote Link to comment Share on other sites More sharing options...
Valiant Posted September 20, 2015 Author Share Posted September 20, 2015 Can't the radiator is in the way. No problem the pump I have was a bit big, they are under 60usd so it's not the end of the world. Quote Link to comment Share on other sites More sharing options...
nickrock Posted September 21, 2015 Share Posted September 21, 2015 Mount it on a small drive shaft off the front of the crank like the early fiats and Massey Ferguson do it sits in front of the radiator 2 Quote Link to comment Share on other sites More sharing options...

No problems though. I spoke to the guys at the hydraulic shop today they thought they may be able to reverse the pump's action. I think the term was "field reversible" I'll take the pump in tomorrow.
