3B injector pump " O " ring

[racerX]

Howdy mates:

looking for a part no. for " o" ring seal for 3B injector pump ( i.P. ) that fits outside i.p. mount to oil pump/ timing case

the one I got from toyota is too small - should not stretch so much -

anyone know the correct part no. and or dimensions of correct " O " ring

cheers

For O rings I never bother with Toyota or with vehicle-specific part numbers. I just take the old one to an engineering shop and select the right replacement myself. (The shop I use has trays of them that I can access myself.)

Very cheap this way too.

O rings are never Toyota-specific (Well I've yet to find one that is anyway.)

x2. The material they are made from (viton type) is more important then where you buy them from.

Howdy mates:

cheers ya for the reply's - the issue is that my " O " ring is not there - probably why I had so much oil and gunge around this area - I would think either was assembled ( previous work) without or the biodiesel completely ate all remnants - though I opt for choice 1 as there is no residue or anything to suggest biodiesel leaked anywhere around -Or any evidence that rubber was eaten away - if it were a rubber compound - I went to a seal shoppe and grabbed 2 of the approx. size i think I will need - one Viton and another ethylene propylene - as I have nothing but the diameter of i.p. as guide - not certain how thick - etc.

Now you have me confused although I will admit that on my truck the VE pump is driven by gears off the crank imersed in engine oil. If the 3B is different, then disregard the following warning. If there is no seal on a drive shaft of a VE pumpwhich is gear driven from the crankshaft, it will dump diesel into your engine oil. The first sing of this - for someone who regularly checks their engine oil - is the level of the engine oil has increased. The second sign that this has happened is B A N G !

Don't run your engine if you suspect this seal is gone or is damaged.

The Boeche Zexel Fast Moving Parts database might help you locat the part number for the seal. http://www.zexel.com/boschzexelpn.htm. Enter in the part number from the plate on your pump. The number should look something like this "NP-VE6/10F2000RNP183". At least it will have the VE in it. The search results will give you an exploded view of the pump with the corresponding part names and numbers. If your pump number has no hits it just means that it is so old they don't have it on their public online database. You will have to go to a Bosch certified fuel shop. They will have access to a much larger database and in a matter of seconds will be able to pull up an exploded view of any bosch built or licensed pump. Next, identify the seal and ask them for one.

Also, make sure you time the pump properly when you put it back on. Unless you have the bosch gauge, you will not be able to get it right by just lining up the timing marks. The timing marks will get it good enough to run to a shop.

I think RacerX is saying there is an O-ring somewhere here?

But this picture is of the injector pump on a B engine and I think many of the parts on a 3B injector pump may be "mirror-image" because I think their pump is on the other side of the motor.

If so ---- Toyota lists a "gasket here" (doesn't say if it is an O-ring or not) for both a B and 3B engine as part number 90301-77001 (for BJ4* vehicles)




PS. This same part number is listed as applying to a 3B-engined BJ60 in this part of the world.

Howdy mates:

Refer to FU- 27 in FSM B,3B,11B,13B,13B-T manual - manual shows O Ring exactly where LostMarbels indicates on the schematic included - i now see the o ring I received from toyota is the O ring behind this mounting plate - and the 3B is inline pump - external oil supply , lubrication. I can scan a foto in if y'all do not have the FSM downloaded already - LostMarbels: Cheers ya for the schematic - I would not have known of this other o ring - now I see I have some more work to do before buttoning up - where the i p mounts to timing case I have a good deal of leak /gunge - figured it was the i p seal

- First major work I have had to do to this truck in 7 years besides dynamo and leaking fuel tank

enjoy weeks end:
