brockwood Posted June 18, 2015 Share Posted June 18, 2015 (edited) Hi found the truck in 77 recovered it with uncle had been from new a mobile stone crushing plant so no cab. Didn’t really know what we had pre computer age has a winch on right rear wheel so thought military or colonial special based. was is missing carb, mag, oil line to timing cover, bonnet, alloy trim, fuel tank, rev gear, uncle moved away and project was in limbo till now. We have unseized the motor. Today got the clutch released and working on freeing up the gearbox and transmission brake. Found some old pics from 77 and a link to some vids . when the chassis was shot a few years ago we didn’t know what we had we now know its basically an enlarged j model with a larger engine rated at 50hp but actually over 60 but it apparently dropped valves so was short lived it’s an f head the follow ons I think went back to side valve. I am lucky enough to have a late j model owner’s manual with the same engine which is a help https://i.ytimg.com/vi_webp/6w8uODrNcBg/mqdefault.webp https://i.ytimg.com/vi_webp/ZVMYwU-UN3A/mqdefault.webp https://i.ytimg.com/vi_webp/rRBarmXh26k/mqdefault.webp https://i.ytimg.com/vi/EUpHx3CDvas/mqdefault.jpg mucked up link go here https://www.youtube.com/user/edgiee27/videos?view=0&shelf_id=0&sort=ddand look around Edited May 27, 2019 by brockwood more imfo Quote Link to comment Share on other sites More sharing options...
nz2 Posted June 21, 2015 Share Posted June 21, 2015 Interesting to view your videos of working on the engine. Please keep us advised of progress. Is there a chassis number stamped on the left front chassis dumb iron? Also any stamped marks about the king pins. I've been trying to relate these stamped numbers to production or series numbers to help date stray axles. Doug Quote Link to comment Share on other sites More sharing options...

Redherring Posted July 9, 2015 Share Posted July 9, 2015 I really enjoyed watching your videos re the Thorny engine and chassis. The commentary is a big change from the odd word attached to the odd photo... as is the norm here. You have inspired me to have a go at this form of communication.

Zuffen Posted July 9, 2015 Share Posted July 9, 2015 For gaskets try these guys. I've used them in the past and they're very good. Located in Hornsby in Sydney's north. http://www.swansonsgaskets.com.au/setup.htm Quote Link to comment Share on other sites More sharing options...

brockwood Posted May 27, 2019 Author Share Posted May 27, 2019 Hi have been doing a little we managed to source a radiator thats copy quality the old one got mislaid. on inspection of the stuck gearbox which we knew had no reverse we found it had no plug in it was dry and had a rats nest in it. So after a rinse it was filled with oil and left to soak a few days latter we put a spanner on the top shaft and with gentle rocking after an afternoon it came free. It’s now off getting a new gear cut. The gear appears quite fragile over the drive key after allowing for the depth of teeth refers to pics there is not a lot left. the reverse idler the loose gear and shaft in pics is constant mesh and had sized we suspect causing the breakage it had wiped out bearing material that had splayed out and jammed it on the case it took quite a lot of getting out 1 Quote Link to comment Share on other sites More sharing options...
Old Bill Posted May 27, 2019 Share Posted May 27, 2019 Very like the J in style. Our reverse gear idler bearing was completely worn away as well. I find this odd as there is no load on it for most of the time but the bushes typically disappear. Good to see you making progress!

David Herbert Posted May 28, 2019 Share Posted May 28, 2019 Could be caused by people putting EP90 oil in there. It eats bronze / brass even without a load. David Quote Link to comment Share on other sites More sharing options...
john1950 Posted May 29, 2019 Share Posted May 29, 2019 (edited) It depends on the type of Sulphur used in the oil, as one type (active Sulphur) reacts with the copper and brass in the bushes and worm wheel. At higher temperatures the reaction is greater. Edited September 29, 2019 by john1950 correction Quote Link to comment Share on other sites More sharing options...
Tomo.T Posted June 2, 2019 Share Posted June 2, 2019 Good to see your progress. I came upon some notes I made concerning these vehicles. There were Q types in military service in the Great War, they had an increased payload of 5 tons, but they all had the 40 bhp M4 engine, as fitted to the J type. BB4's became available from 1924 rated at 50 bhp. I dont know if they were ever taken up by the military. Good luck with the restoration. Tomo.

nz2 Posted September 11, 2022 Share Posted September 11, 2022 Good to see the progress. Is there a serial number on a brass plate on the engine and also a stamped number on the left front end of the chassis. That would allow a date of manufacture to be gained. Not many Q models about, I found the rear axle of one here in N.Z. and a front axle at another location. The rear axle is so different to the J having raised sections as overriders about the springs.

brockwood Posted September 12, 2022 Author Share Posted September 12, 2022 Hi i believe its bb4190 could never find the chassis no must have another look b Quote Link to comment Share on other sites More sharing options...
nz2 Posted September 12, 2022 Share Posted September 12, 2022 Some searching has found BB4 190 as fitted to Q chassis no. 10910 leaving the factory on 30-8-1924 However the engine may not be the original as things got swapped about over a vehicles life. hope this helps Doug Quote Link to comment Share on other sites More sharing options...

nz2 Posted November 26, 2022 Share Posted November 26, 2022 Where were these numbers stamped? Can you show a photo of the location. I have found similar stamping on a gearbox and take them for the initials of the assembler or foreman doing the work. Doug Quote Link to comment Share on other sites More sharing options...
