JCB 8014 - Track Tensioning

[GazCro]

looking at your drawing and this is pure speculation, i'd say that item 6 screws in/out of item 4 (or a threaded plate, not shown, in the carrier frame, pushing the machined step on the end of 6) into 4 increasing the loading on the spring (5) .. I assume plate 1 is fitted to the rear of the idler carrier with 4no. bolts (2) and washers (3) ..... the castellated nut with securing split pin on the end of 4 keeps everything attached to plate 1 ...... presumably item 6 needs to have something to bear against in order to preload spring 5 with the plate at the end of item 4, which i'd assume is shaped thus to prevent it turning and slides in some sort of guide.
as said pin 9 is presumably secured by something attached to the cover plate to stop it free rotating
But .... WTF does 6's bolt head bear against, if 6 isn't threaded into a plate in the track frame??

I think bolt 6 (the adjuster) runs through a thread in the track frame to push against 4 but it's been a long time since I've had to bother with 801 tracks. Either way doesn't matter 6 is the adjuster which is all he needs to know.

I agree, it's very basic but does have some grunt for a little machine. At the end of the day it's saving my back from breaking and that's fine by me As for flat ground, not much of that about in my neck of the woods

Same here Rocky. I have a 8016, it may not be the best machine out there but it serves my needs. Only wish that it had an expanding undercarriage.

I have the manual for the 8014/6/8 series. Give me a shout if there is anything else you need.

That's very kind of you

had a couple of days on one back in '16 doing some footings for a mate ..... was a tidy little thing, if you kept it cooking ... leave the sticks alone for a few minutes and it sort of went to sleep and had to re-awaken it, 'fore it'd get going again ...

fuel gauge non functional on that one too ..... hence the open bonnet

produced some passable results and down a long way in places

tight old place, but nice digging on the whole ...... life would've been easier if the skips'd turned up as promised .... too tight to get a grab truck into

Some neat work there

A mate has one and I love driving it tbh, really smooth to operate. Just have to plan slope-work carefully!

cheers ........ it'll do for a "welder without a shift"

To be fair they are a machine of their time and jcb were behind most others in bringing better spec and expanding tracks to their smaller machines.

They still build the exact equivalent in the 15c it's what alot of hire companies seem to have round here especially Travis and jewson

The 8014 I use is the square boom one and I think it's great lovely machines to operate.

One of the reasons I never understand the JCB bashing as tbh I have yet to use a JCB machine that isn't nice to operate regardless of people's opinions of build quality. And with the 8014 they are so simple there isn't really anything to go wrong with them.

The 8014 really is poverty spec hire machine. Not much to go wrong and actually quite nice and smooth to operate
But geared pump
Single speed tracking
Fixed undercarriage
Short blade carriage

As long as you accept the shortcomings they do work well nice big arse on them so stable as long as you are on flat ground
Easy to grade with smooth controls
And very little to go wrong and the cab is enormous

I had a 2006 8014 for more than 10 years and it was bullet proof - smooth fast basic - spot on.

If anyone wants to own a piece of classic 8014 history, I have my 2001 (Good vintage year 2001 was) 8015 which I will be putting up for sale soon. Has more buckets than features, owner operated for the last 11 years (cant say the same about the previous owner) Many new parts (its needed them often enough) but starts, digs well and as the thread above has decided - these are great machines - grab one while you can, especially as its value might increase considerably once I become the UK's premium operator!

8014 track adjustment, the hex head bolt with the pin through is the adjuster, it would tighten clockwise and loosen anti clockwise, if the spring is full of clay it will leave the track tight even when de- adjusting, the front idler bearings need to be checked as they do regularly collapse and leave the track loose, tightening them will just cause further damage, if all is ok, lift the track to be tightened off the ground, turn the track to roughly where it is at a tight spot, rest a 14mm/ 9/16” head bolt on the track beneath the nearest bottom roller to the middle of the track, tighten the bolt clockwise until the bolt touches both track and roller. The pin on the rod was a lock pin and once it would have corresponded with a cover plate with a slot on the inside, the cover plates were sometimes left off. Hope this helps.
