After returning home shortly after leaving on Sunday morning with an 80 that was chuffing like a steam engine I found my no5 injector blowing by.
Went to pull it this morning and found the bolt finger tight!![emoji33] That'll be the cause then! So pulled it, and pulled it, and after much cursing and about 1/2 hr with a pry bar under it I managed to get the blighter out. Spent the next 2 hrs cleaning up the hole. Got some 20mm plastic conduit and put some double sided tape round the end with some aluminium oxide paper wrapped round it. Did the same with some 15mm plastic water pipe but turned the abrasive round the end of the pipe.
Hey presto, two diameters of pipe to attach to a vacuum cleaner and scrub away at the inside of the injector hole without dropping bits into the cylinder. [emoji6][emoji4] the smaller one cleaned up the seat a treat with the abrasive turned round the end and full dust extraction from the vacuum cleaner (fingers crossed).
Refitted the injector and new seal and O ring and put it all back together. Torqued up the bolt to 39 Nm after giving it a run in and out of the thread in the head to make sure it was free.
Then on to the next job. Front prop, front UJ and tested out my theory of being able to replace it while still fitted to the truck. Hmm doing the Mk1 Shogun one like this was a piece of cake…not so the 80 as I had to give some good hard whacks with the copper mallet to get the caps moving. But move they did, enough to then get one out and a puller in to get the second out on the prop shaft end. Then used the puller to push the cap, yoke and cap through and one cap out the other side. Alas I was then stuck with an otherwise free yoke and cap inside the lobes of the UJ. I ended up getting the grinder to it and cutting through the yoke to free it all with no real dramas.
I'd put the caps in the freezer earlier in the day which was both good and bad. They were a bit tight on the yoke but fitted nicely into the holes in the lobes of the UJ with a bit of persuasion from a Crab Clamp which was perfect for pressing them in. An ally block took care of the last knockings of the second cap to save pushing the first cap too far in.
And Bingo, job done…err, well no [emoji30] I realised I had put the new yoke 90 degrees out so the grease nipple pointed at the prop end lobe rather than into space. But using a 10mm spanner on the square I turned it enough to point where it was accessible. [emoji3][emoji3][emoji3]
So…the theory, well it is doable but nowhere near as easily as the Shogun (1/2hr) and the knocks I was having to give to start with were making me think I might damage something in the diff but all is good.
A quick couple of knocks to seat the caps fully back away from the yoke and all's well.
