Pete,

Glad it worked.

As to getting the gear off, again, if your sensible, try a couple of large flat bladed screwdrivers, or similar and gently prise underneaeth. Luckily mine wasn't too tight and came off very easily. Alternatively use a gear puller. For a one of job such as this you'll probably find a very cheap Rolson brand at one of your local cheap DIY places. Alternatively

They seem to have quite a few on offer, you can guess at the quality, but as I said for a one off job...

OK, new seals are in place and pump reassembled.

The new filter comes with a white plastic washer and a smaller rubber washer. Any suggestions on where these should go? Evidently the spring-loaded plate inside the housing holds the filter in place, do the seals go between the plate and the filter?

Cheers
Pete

Pete,

If the white washer is about 1 inch in diameter I think it goes between the filter and the pump body. The rubber washer is probably for the bolt which fastens the outer can to the main body.

Hi,

There is no washer in the packs which will fit between the pump body and the filter. The outside diameter of the white washer is the same as the inside diameter of the filter.

Looking back at powerrrabbit's post to the Vapormatic parts, I have accounted for all the items listed beside the filter pack, so maybe there are no seals or washers to be fitted to the filter.

hmm... another problem. The gasket between the pump and the engine block is missing (#22 on the diagram), and I guess it should be replaced in any case. Looks like someone has previously used a mastik-like sealant on it.

Should the gasket be readily available?

Cheers,
Pete

the white washer your talking about is probably for the fill/level plug? probably just as easy to make a gasket

Hi the plastic washer is for the filler plug and there should be a thin rubber washer either side of the filter , i put the plastic washer in between the filter too and didnt notice the rubber ones were missing untill i took a closer look at the old filter after i had put it all back together , well mine is still like that at the moment with no ill afects yet ? :roll:

Why dont they come with the rubber washers anymore ?????????

Probably in order to keep the price down Martin, like no longer supplying the locking nut with the steering joints or the proper dirt excluders.

Can't you peel the rubber washers off the old filter and stick them either side the new one?
Pump to front plate should be easy enough to make, just make sure that you cut out all the required nessecary holes.
The white larger plastic washer is the neww filler plug seal, it should have 3 lugs on the inside which hold it in place on the top end of the thread so you won't loose it, you screw it on the plug to fit it.

Hi Powerrabbit

Unfortunately one washer was damaged last time it was fitted , i was unshure if there is a special type of rubber that they use in a pump that doesn`t break up and clog the filter ?

Thanks Martin

Think it's a rubber/cotton composite Martin.

The washers and seals are pretty academic now, as I just sheared one of the mounting bolts putting the pump back on :( ************. Does that front plate on the engine come off as a separate piece? If so, what are my chances of finding a replacement?

Pete

EDIT: Lucky escape, turns out it was a grub screw, easily removed, and have replaced with a bolt, cut to length. The pump is back on! Phew.

Well, after all this work replacing the seals inside the pump and ram... the steering is now worse than ever. It was better for a while, but I had 'er out last week and at times it was almost impossible to turn the steering wheel. Even revving up didn't help much.

Steering is at its worst when the tractor is stationary, and improves more with speed than with revs.

I'm now wondering -- is it the orbital (?) unit attached to the steering wheel..... OR .... damage to the pump itself (there was some scoring on the inside of the pump body, where the rotors are.... I can't say how serious it was, I've no handle on the tolerances it operates with)

Cheers guys
Pete
