Panic! - wtf is this engine!

The Mad Hat Man · Apr 28, 2007

hi guys
stripped front of engine to do timing chain - it dont look a bit like the manual!

here are piccies of wat i got - according to manual I shud have a ratchet and pawl adjuster mechanism - which this obviously aint. Any clues - it is supposed to be a 2.5 defender petrol lump (1985). It could, of course be a later lump - or summat quite different.

looks a lot like a 2.25 thou the tensioner is different ah think.
can you not trace it with the injun number??

I had a bit that looked summin like that on me BSA.

Trewey · Apr 28, 2007

my BSA has got an 18" barrell, a sound moderator and a 4-12x40 telescopic sight. it aint got nuffink that looks like that!

HybridGirl · Apr 28, 2007

Trewey · Apr 28, 2007

Daz800 · Apr 28, 2007

Dont check the log book, look on the engine.

ffs daft, take a piccy of the engine from the top showing the rocker cover

The Mad Hat Man · Apr 28, 2007

The manuil sez they are both the same except a diff crank - so cant tell that easily.
not sure wot a view of the rocker cover will achieve either, Yella.
I shd have posted the engine number tho - it is 17HC41030.

Thanks fur ya help, folks.

2.3 horse power. or 3.2 donkey power.

The Mad Hat Man · Apr 29, 2007

Problem resolved - thanks guys for info and feedback.
it appears (small supplement to manual) that the 2.25 and 2.5 have different timing chain adjusters. I have posted pics below. the ratchet and pawl version is for the 2.25 engine - the block type is for the 2.5 engine.
Also for your info, the method of determining a worn chain is -

2.3 engine
If the last tooth of the ratchet is engaged in the pawl (1in pic) the chain is excessively worn and should be discarded.

2.5 engine
The timing chain tensioner check dimension (A in pic) with a new chain and sprockets shd be 14,22mm (0.5in) approx. - for a fully worn chain is 27mm (1.06in).
now onto next jobby!

slob · Apr 29, 2007

the 2.25 had two types of tensioner fitted. dun know if the later type is the same as the 2.5 though,
one would supect it is

The Mad Hat Man · Apr 29, 2007

Well - as mine has the second type - and is supposed to be a 2.5, I suspect it is.

thanks fur ya help yesterday.

slob · Apr 29, 2007

nae problem

The Mad Hat Man · May 2, 2007

Anyone got a spare timing chain cover for a 2.25 or 2.5 Deepender engine?
I believe its the same cover for Petrol or doozil?
