Vintage Bristol Dozer repair part 1

I'm doing some repairs on the old Bristol Bulldozer I picked up for $500 for last month. It needs a lot of work, this time I'll concentrate on rebuilding the water pump and thermostat housing, both are in pretty bad shape, and it looses most of its coolant after 10 minutes running.

[@davidfuqua7513]

So I watch this guy make his own power and I think.. he must have a background in electrical engineering. Then I see him solve complex mechanical problem and I think… he must be a mechanical engineer. Now I’ve just decided that he’s just a soft spoken genius with a beautiful life and family and my spirit animal! Im 53 years old and when I grow up I want to be like Marty T. I literately can’t wait until the next video. I may have to force myself to not watch for a while just so I can binge watch later. I might need to talk to someone about this. 😳😂greetings from Alabama, USA!

[@nigelmarx3578]

Jaysus, I can't believe how many people come here just to tell him what he's done wrong, forgot to do, or could have done better. It's his dozer, his channel, his life. Watch, learn, enjoy.

[@MartyT]

Thanks man.. I do appreciate constructive criticism, I am learning from some comments

[@steveaguinaga3821]

I'm pretty impressed. Good work he does. My only question is why isn't he painting clean and pretty? Especially while he has bits all apart. Fan & water pump etc..... I guess he's just going for that look

Yeah, these people need to shut the fuck up.

This gents is how a real mechanic fixes vehicles, something that lost on today's modern cars and machinery. Thanks Marty for showing a few 'tricks of the trade' a lot of young mechanics can certainly learn a thing or two from you. Been a mechanic myself for about 27 years, nice to see the old school repairs with the lathe work as well, brings back some fond memories.

[@NitroGuyJH]

I love this type of restorative work. It’s not a complete disassembly of each and every part and restored to brand new quality, it’s a clean everything good, complete a full service and repair anything that would hinder its ability to be worked, then actually be used for what it’s intended purpose was created for! Absolutely love this stuff! Can’t freakin’ wait for the next part Marty!

[@undissatisfied1557]

The thermostat was some pretty impressive engineering, gotta say. I wouldn't have thought to do that.

[@doncodman913]

Yes very good work ,but isn't it restricting the flow of coolant ?

[@johndowe7003]

@@doncodman913 thats the idea behind a thermostat

You don't want the coolant too fast, it won't spend enough time in the radiator cooling off.

This brings back so many memories of when I was a kid with my dad my grandpa and my uncles in the winter time we would pull them equipment in and rebuild anything that needed to be rebuilt for next year's login season and watching you build that shaft up and milling it down is just exactly what my dad and my grandpa would have done thank you You're bringing back a lot of memories to an old man Good memories

Your corded cordless drill gave me a good chuckle. Good on you mate these “will it run” series are a treat to watch.

[@gallente4TW]

"... See that bearing in there. Its pretty shagged..." This is one of the reasons I enjoy Marty's channel. He doesn't mince words. Plus, there's definitely some sort of familial thing between Brit's, Aussies and Kiwis, each using similar or exactly the same phrases as each other. Off topic I know, but years ago I lived in a flat with Kiwi neighbours. There was about twenty of them all sharing a flat. And it was party central almost every night. They all worked hard, or were students and a nice bunch of blokes. They would do anything for you and never expect anything in return. Except maybe a beer in the local pub when you saw them. My girlfriend moved in with me, and had trouble sleeping cos' of the raucous partying next door. I asked a couple of them in the pub if they could keep the noise down just a bit and maybe end the party a bit earlier than five in the morning? They always laughed at me. Not in a dickhead way. But they couldn't believe they were being asked to do something that was alien to them. They sympathised and that, but it was like asking them to ritually sever one of their own limbs. This went on for a few weeks and one night in the pub, I'd had a few and asked again if they could town it down a bit. The usual happened and nothing changed until I told them that Nicola, my girlfriend, was pregnant. It was like a bomb had gone off. You'd never seen so much contrition and apologies. It was weird. That night they still partied but it wasn't as loud and ended much earlier. The following Monday à good mate of theirs was arriving in London and was gonna stay with them. Now normally, this would have meant ear-defenders for me and Nicola, lol. But they invited us to their flat for the party and my god, the kindness and respect they showed Nicola was unreal. One of them, called Richard, or Rich' (for months I thought his name was Reg', short for Reginald because of their accent when calling his name out) who was built like a prop-forward but had long blond hair and worked as a hairdresser in Golders Green. He sat chatting with us for hours and explained that all I had to do was tell them Nicola was pregnant and everything would have changed. I sort of lol'd and asked why? Rich' said that back home they were always brought up to respect a pregnant woman like they would someone old. Great bunch of lads who often talked about The Land of the Long White Cloud, and introduced me to what I called a buried bbq. Dig an hole, line it with rocks, wrap your meat, yams, etc in foil and chuck that in with coals and dirt on top of that (I think) and fuck off to the pub. I hadn't tasted better cooked meat EVER after a night in the pub. 😊

Nice fix on the water pump shaft, and the retro fit of a newer style thermostat.

[@Zeus_a_Gentle_Staffie]

Thanks again Marty for bringing back memories from back in the day. As a kiwi living through ‘50’s & ‘60’s the only way to buy a new car back then was to have overseas funds. So we had to learn the skills you show in your videos to keep our old cars running. Glad to see some kiwis are still maintaining those skills. 👍

[@calvarybuilders5689]

One thing I learned with the dastardly little grease buddies on trailer hubs is that if you over pack the grease in it, it can blow out the back seal, I think it's better to hand pack your bearings before installation and fill the cavity by hand with grease and you'll be good for 30 years 😃

[@wjheald]

You are really taking me down memory lane. First I saw the DB 990 video, the first new tractor we had on a hill farm I worked on as a kid. When I left school I went to work for Bristol Tractors at Sough Mill, Earby, UK, as a trainee cost accountant (1969, £5 per week £4-8-4d) take home). They had just completed development of a tractor, with cab, that could load at the front and tip behind ( The Bristol Taurus?). They were then taken over by Marshall-Fowler, a company which started out building steam traction engines. Bristol were connected to Jowett Cars, made in Bradford.

[@tolbaszy8067]

Your camera work is very intuitive and shows just enough to understand the fix! The editing is spot on! Your dialog has got to be total fabrication, or you have zen master patience! Thanks for making the videos; they are addictive!

[@roosthrower]

Great job Marty. Surprised the bearings didn't come with seals as they are exposed to alot of dirt, water etc especially the outer one I would of got sealed bearings removed the inner seals and left outers in as it has grease nipple. Never seen anyone use permatex on the hoses. Good idea. Never seen a thermostat that tight. Great bush job on the thermostat. Supercheap must love you in your hometown, they prob watch all your vids too, Handy little dozer. Such a good feeling having it all fixed, serviced knowing everything is A1 but rusty. Those cover bolts for track adjusters look like a time consuming job. Hopefully some heat on nut and it will undo if there's no seals around it Great video.

[@gallente4TW]

Very resourceful rebuild. The thermostat housing is very much like that found on Triumph TR-3 cars. The bellows thermostat was designed to block the bypass port when it opened. You may not get full flow through the radiator without that bellows thermostat blocking the bypass. On our cars, using a modern thermostat as you did, we block the bypass port with a plug. Just a thought if you have cooling issues. Great work.
