Fun with Fronterrors or Gear driven oil pump moments


Recommended Posts

So I, as some of you are aware by now, have a penchant for Frontera A models. If you don't - shame on you, this place etc.

 

 I have one of Vauxhalls finest rebadged Isuzu 4x4 - assembled in Luton with a Turbo-charged Opel (CF-type) diesel...

As usual lack of regular oil changes has led to this -

So I located one of these. From a friendly Opel dealer. For a lot.

Nice paperweight m8.... bet you could get two Laggy for that ££ (but need a really large desk) ;)

how much was the cog?

 

£42.00 + Vat 

 

Not bad I guess for a 22 year old part/last produced engine.

What's that 2.3 diesel like? I've heard they're fairly terrible but I like rubbish old diesels.

 

I love them - glacier-like would describe them to most people but a well (properly!) set up one is a decent drive. Lots of horror stories but all those CF owners can't be wrong. Oh, wait....

 

Slog on all day. Very understressed in standard-ish trim. Just watch oil pump wear if servicing is neglected....:-D

Oil pump end cover - 6 hex screws holding it on to housing.

 

The large 'bolt' is end of oil pressure relief valve.

Slacken 6 hex screws and remove  - remember to miss oil drainer and watch  (with slight horror/air of resignation) oil make it's way inexorably up (down) your arm....

 

Both driver and driven gears will slide down their respective oily shafts as you remove end cover.

Yay.

Splined/toothed shaft is driven via injection pump/crank gear. There is some wear but even I draw the line. 

 

Sometimes.

No oily armpit for me today. A little part of me was disappointed...

Some light cleaning of housing before cover/leaking oil prv attended to - not that I didn't resealed it properly before. Honest. :-)

Then on to cover - gently held in vice for old gasket removal, prv remove and reseal.

Yes, it's a long spring that really doesn't want to be compressed whilst attempting to refit retainer with oily hands. At all.

Apply a constant pressure with twisting action and swearage. Retrieve spring. Repeat.

Insert picture of perfectly formed Vx grey sealer gasket here. Whoops.

Refit cover while holding new /old pump gears in place without disturbing 'gasket'. 

Refit all six hex screws without dropping any on your head/in drainer or watching them roll away.

Torque (wiv and actual tool an' everyfin') and wait appropriate amount of time (12 hours) before starting. Or 45 min because I need to load workshop.

Check for leaks and oil pressure - none yet and some. :-)

 

Upcoming - 

 

Check oil pressure after sustained high-speed run (hahhahahahhahah - 'high')

Check for leaks on Monday after minor Torrey Canyon on drive

Replace turbo with another one (about 2ish mm radial play!) 

Wonder if odd clicking noise is vicious fan coupling about to seize/explode.

Repair drivers seat base webbing.

 

:-D

I'm surprised the steel gears wear before the housing , nice to see someone bothering though . Quite a frontera fan on the qt

Posted

The end case wears. Gears usually wear due to lack of oil changes. 4500 miles on mineral is the way forward.

Well all looks very easy from the pics which must mean it's actually a total bastard when you try to do it yourself.

 

Is this the same pump on the petrol engines?

Posted

I am impressed! I remember them well when new, being regarded as a bit of a lash-up; and only a handful of years ago I looked at buying a similar one to yours, and the owner was complaining about parts problems.

Posted

Glad to see you've still got this. It was a bit of an arse clenching drive from Hampshire when I drove it back, all that overheating I've got some pics of it with an RAC van. Does it still try and overheat under pressure?

Posted

Nope. New rad and thermostat fixed it. Rad was 3/4 blocked by baked mud.

 

Top hose was a bit leaky but fixed as well.
