91 2TE diesel pump leak


Recommended Posts

g'day, can anyone tell me if it is an easy job to replace rear seal (where injector pipes come out) on a 91 surf turbo diesel 2.4LT as mine is peeing out diesel when running. i think it is called the distributor seal. i have checked top seal and it is fine. talked to a diesel shop guy today and he said it is a tricky job if you don't know what you are doing but i am fairly mechanically minded and not sure if he was just saying it to get the work coz he said it will cost between 200 and 300 dollars to do. this is after he said the seal is $7.40. any help would be appreciated.

cheers

regards

hi brian

the pump in question....is it the one that has an alloy body and a steel dissy block??.....and what seal exactly is leaking??...can you be a little more exact please.

there is no rocket science to getting the steel dissy block off the pump body.....just take your time and use common sense.

cheers

It is the efi with alloy body and steel dizzy block. it is leaking at the joint between the main body and the steel distributor block where the four injector pipes come out of. i understand there is a single rubber seal inside this joint between main body and dizzy.

i have been phoning around this morning about used pumps and now i have to get a diagram of all the timing marks coz i was told if it isn't fitted dead on timing it can bend valves. the local diesel guys want $1000 to fit new seals to my pump. i don't have that kind of dollars and need vehicle asap.

hi bryan....

yes it is true that you can bend valves if you dont get the timing spot on......been there done that myself!!!

when you get an exploded view of the internals of your pump you will understand why the diesel repair shop guys charge the prices they do.

i have a non electronic injector pump and i rebuilt/repaired it myself a little while ago now. and i can tell you for a fact that if you dont have that diagram and a good clean clear table to work on....its gunna make rebuilding that pump so much harder. there are HEAPS of small parts inside (the non efi ones) that all fit together in a precise way.

if you choose to take the pump apart yourself be careful as there are several strong springs inside that can and will pop out if you arent ready for them!!!

cheers

g,day

my first post.

you have a 2lte surf..as i do

you can pull the pump apart yourself but unless you fluke it when putting it back together it will never run again.

you need specialist equipment and facilities to calibrate these pumps.

i too work for toyota..in a parts dept.

you have 2 different kinds of 2lte pumps

22100-5B300 which is listed for EFI surfs up to 11/90

22100-5B303 12/90 onwards

the 22100-5B300 pump is $260 (yes thats two hundred and sixty dollars) brand new from a Toyota Dealership.

I have fitted several of these pumps to 91,92 surfs both auto/manual.

They will happily run on any 2.4 EFI surf is what im saying

Take my advise and forget trying to get yours fixed..buy a new one.

check out toyotasurf.asn.au and have a read...lots of info

hope this helps
