Bosch pump refurb - WiNgNuTz - 28-11-2012
Ok, so most of you probably know about the 99p (+ £20 p&p) bosch pump i won from fleabay.
Ideally i was hoping to strip it down and rebuild it myself before fitting, but im struggling to find any kind of guide to stripping the thing down. Ive found a step by step guide to putting it back together, but working backwards through the process is a little confusing at the moment, maybe im just not reading it right.
My question to the diesel heads out there is, should i bother doing it myself, risking losing parts, or putting it back together wrong, or anything else that could go wrong, or should i have it done properly by someone who knows what they're doing?
My original thought was if i strip it down and do it myself, i can gain some more understanding to how they work, and what each part does.
The problem lies in the fact that i dont get on so well with reading manuals, unless i get stuck. I learn easier and faster by getting hands-on.
Thoughts people?

if you're anything like me, i'd learn by just taking it apart in a vague logical order and trying to take note of where shit goes for when i bolt it back together, with a manual for refernce if i need it. i pretty much learn how shit goes together by taking it apart tho,..
i'd just attack it, personally
RE: Bosch pump refurb - Danny2009 - 28-11-2012
I'd say get the spanners out, take pictures as you go along
Like you say you will learn more taking it apart yourself and at the end of the day it only owes you 20 quid ....
RE: Bosch pump refurb - Tom - 28-11-2012
Darren usually does this for people if he has the time
Might be worth getting in touch with him. I usually consider doing stuff myself but for the price it would cost for Darren to do it i just give it to him haha
RE: Bosch pump refurb - WiNgNuTz - 28-11-2012
Hmm....thats not a bad shout, might see about taking a trip down to lobbland to see darren, and maybe have him take me through it. I would really like to do it myself, but would feel a whole lot more confident having someone on hand who could offer advice/help out if i get into trouble!
Maybe im just being a bit paranoid about the whole thing, but it'd also be nice to go and meet the legend himself, and get some pointers from him! 
Obviously that depends on if/when darren has time, and when i can get down there! Who knows, might be able to get the lines and injectors, make a weekend out of it (again, depending on what darrens up to), and get the conversion done while im there!
RE: Bosch pump refurb - cwspellowe - 28-11-2012
Look in the guides section fella, the thread I posted and there's another one called "useful information" (i think it is?) that has a link to a full pump rebuild. Plenty of info there, get reading and you'll have it rebuilt in no time!
RE: Bosch pump refurb - Dave - 28-11-2012
Depends if you 'need' your car on a deadline. They are easy to f*ck up in a sense if you don't know what your doing, but most guides online for assembly will point out the key things.
RE: Bosch pump refurb - WiNgNuTz - 28-11-2012
Im still running the Lucas pump Dave, only got the Bosch pump at the moment, no lines or injectors yet, so no time limit on the rebuild, but obviously would rather have the Bosch on and running sooner rather than later!
RE: Bosch pump refurb - Dave - 29-11-2012
Yeh but what im saying is, you could disassemble it, and reassemble thinking its fine, and then you go to start it, and realise its not working properly, and have to spend the time putting the lucas back on to then fix the bosch again.

RE: Bosch pump refurb - WiNgNuTz - 29-11-2012
@Dave - Im with you now, thats kinda the reason i was hoping to have some kind of help with it. Or have someone who knows what theyre doing rebuild it for me.
@Jenks - Thats the guide i have been looking through, and i did make a bit more sense of it last night, but it still doesnt give me a definitive guide to dis-assembly. Might have another read through it a bit later when ive got the time, and maybe the more i read it, the more ill understand it!
RE: Bosch pump refurb - londondan86 - 29-11-2012
I will hapily do it for ya bud. But as you said you will learn much more by doing it yourself, it's really not that hard, just take pictures as you take it apart to refer to as you put it back together

Hey, I've successfully rebuilt one of these units before, if you want I will come over from Kent to assist you. It is better to have two people anyway. But I think rebuilding it for the sake of rebuilding it is a mistake, I would suggest just doing something basic like the gov mod first before delving into that side of things. Let me know.

Whereabouts in kent are you buddy? My idea with rebuilding it is that it was bought from ebay, very vague description, and it was covered in filth when it arrived, so thought it might pay to strip it down, and rebuild it with fresh seals, make sure everything moves as it should, etc. I'd be doing the gov mod and LDA at the same time.

I MIGHT take you up on that offer mate, if i decide against doing it myself. I really would much rather do it myself, but we'll see!
RE: Bosch pump refurb - londondan86 - 29-11-2012
No worries, just drop me a pm if you do or if you get stuck if you do it yourself
RE: Bosch pump refurb - WiNgNuTz - 29-11-2012
funny you should say that, ive had a crack at taking it apart, and i feel like im doing quite well so far, but when it comes to opening the pump up to get to the governer, i cant get it to come completely apart. Ive given up for tonight, putting it back together so i cant kick it over and break something (other than a toe!), but any tips to getting that piece apart would be handy!
Re: Bosch pump refurb - Dan! - 29-11-2012
A lot of people have trouble with that bit. Iv got a pump here to gov mod tomorrow evening so I might do a demo video for people to watch, it's a pig to explain in words, you have to see how it comes off to understand it lol.
Hope you remembered to mark the throttle arm before you took it off :-)

That would be so much win Dan, nice one!
And yes, i marked the throttle arm. I have consulted and read through your guides a few times before i even plucked up the courage to undo a single screw!
RE: Bosch pump refurb - londondan86 - 29-11-2012
It will probably be easier to watch Dan's vid tomorrow but there are 2 ways to do that bit, the easy way is to gently tap the throttle shaft down leaving the governor attracted to the shaft then lift the lid off. Or get a flat headed screw driver and push the leaver set back to get the governor to disengage which can be fiddly
RE: Bosch pump refurb - WiNgNuTz - 29-11-2012
Lets hope he does actually do the vid then!
DO THE VID DAN!

RE: Bosch pump refurb - n0v0s - 30-11-2012
If you are a clumsy trollop, I wouldn't advise you to rebuild it. Especially if you need it back on the road by a certain day. However, if you have common sense and some patience - it's easy. There are guides about.
RE: Bosch pump refurb - WiNgNuTz - 30-11-2012
lol @ clumsy trollop!
Im pretty confident it shouldnt be a problem, as ive mentioned, im doing this before i replace the Lucas, so got no issues with time. Gonna take it slow, and make sure im doing everything right.
Also, my tosser of an ex-landlord commented on my facebook yesterday (dont ask why hes still on it, i keep asking myself the same question!) with this:
Quote:Cant see the point of taking it apart to clean it. Gunk and a pressure washer will do the same job. If you are rebuilding it, then thats a different matter, however you will need the specialist tools such ad DTIs to calibrate it and measure end float etc which you are more than welcome to borrow from me if you need them.
Now, i admit im a bit of a n00b at this game, but i wasnt sure how much truth this man was speaking, as hes fairly well known for bullshitting his way through life.
Is what hes saying ACTUALLY worth listening to this time?
RE: Bosch pump refurb - 306Puggy - 30-11-2012
No, not at all. Although having said that, I don't know if there might have been some problems with mine due to the rebuild, because they would have been masked by the blocked fuel filter.
RE: Bosch pump refurb - WiNgNuTz - 30-11-2012
wtaf are DTI's anyway?
RE: Bosch pump refurb - 306Puggy - 30-11-2012
It's something to set the pump timing I think. The Bosch manual mentions them a lot.
RE: Bosch pump refurb - londondan86 - 30-11-2012
Ignore what he said and crack on I say, my rebuilt pump has been going strong for nearly 2 years now and no reason why it shouldn't last another 10-15 tbh
RE: Bosch pump refurb - WiNgNuTz - 30-11-2012
Thanks dan, i figured it was BS as usual, but i thought id ask on here as well, just in case he actually happened to be speaking sense for once. Should have guessed really!
