Advice re parts/repairs for Gladys please

We are the very lucky new owners of Gladys. She is in the repair shop and has a few issues that we are trying to sort out.
Bernie has been very helpful, but I don't want to keep pestering him.
I've got a list of things that I need from the garage and I am trying to source them from various places. I'm doing OK but I am not 100% sure what I have found is the right part. So .... can someone check before I order please?
If I list the parts one by one with the part number and source I have found is that helpful?
FYI - 1971 Commer PB Wanderer.

1 Clutch Master Cylinder is leaking. Will a repair kit be enough or can you buy the whole thing? Is ours (1971) early or late?
Speedy Spares seems to have Master Cylinder Repair Kit but I worry the time needed to repair negates the saving??

5040359/SSB716 Master Cylinder repair kit
or SSB993 Master Cylinder Repair Kit ( later type, with 2 ring seals) £5
Is there such a thing as a master cylinder?? You may gather I am Mrs Bombus and have no idea about engines and gear boxes etc.

2 The Brake Master Cylinder is leaking

Speedy Spares has Part Number Brake Master Cylinder (75067246) 4211639 £70

Or should we use a Master Cylinder repair kit, Again do we need early or late?

3 We need a clutch slave cylinder.
Speedy Spares has Clutch Slave Cylinder (75067324) LL13312 Speedy Spares £40 We think the gear box is a J?

4 Rocker cover gasket P106897/JM319 Speedy Spares has Rocker Cover Gasket CI Head £4 is this the correct thing?

5 We need a pinion oil seal for the rear axle - not sure about this?? Any thoughts please?

6 And we need Rear gearbox seal where prop shaft slides in. Pic attached. Looks like this is an output shaft seal which I think we can source.

Thanks so much

Bombus

Hi and congratulations.
Defo buy the new parts for the clutchslave, master and the brake master. I’ve tried and never had much luck with the repair kits due to damage in the bores themselves. Since fitted new and they’ve been great.
Also likely cheaper than the garage doing the seal changes anyhow.
Other bits are available from speedie spares (for now). The rocker cover is correct as I think Gladis has a cast iron head (CI).
Sure Panky will be along soon who is the god of everything Commer :)
 
As Jim says go for the new cylinders if you can as repair kits , in my opinion, are only a short term solution unless the cylinder bore is perfect. Being a 'J' type overdrive won't affect which clutch master cylinder you buy as they are the same for all gearboxes and go for the later (larger bore ) brake master cylinder, Make sure you stipulate the correct oil seal for the 'J' type overdrive (a standard gearbox uses a different seal).
And don't feel awkward asking Bernie for advice as I know he'll be only to happy to offer assistance where he can.

If Speedy Spares don't have what you need try Power Track Ltd as they carry huge amount of spares

Thanks so much for your time. We love her already and took her for a health check as we knew there was an oil leak.
 
I think I can help with 5 and 6
  • Pinion oil seal. Take a look at this link. https://forum.commervanfan.co.uk/threads/rear-diff-gasket.8732/#post-148127 The oil seal is just a generic item obtainable from any bearing supplier online by using the dimensions in the link. I use Simply bearings or Wych bearings. Also read on in that link or here https://forum.commervanfan.co.uk/threads/jennings-restoration.7437/page-16#post-146407for how to get the pinion nut off and on. It's tight! If there is a bad wear groove or rust where the seal seals on the drive flange, I can help with a cheap repair for that too.
  • Gearbox rear oil seal. It looks like what you have is a Laycock J type overdrive fitted to a standard 4 speed Rootes gearbox, so the oil seal is for the J type overdrive, not the gearbox. This link https://www.overdrive-repairs.co.uk/ will take to to Overdrive services Sheffield. The oil seal they list in their list of spares is NOT the one you want, and I don't have the spec here, but if you talk to the very knowledgable proprietor, he can supply the correct seal.

Thank you Panky. That's helpful. Do you think our gearbox is the J and not the D. Bernie said to contact OverDrive in Sheffield for that seal?? And when you say go for the larger bore, can you tell me more?? Bernie has been lovely about me pestering him with Qs but I don't want to be a pain. Thanks so much.

Crumbs you guys are amazing, thanks so much. That's hugely helpful.
 
The larger bore brake master cylinders were fitted to later vans fitted with a larger bore front wheel cylinders, early vans had a smaller bore version although they look the same.
Hope this all helps to get you back on the road for summer, but we needs some pics of your adventures as payment please:):cool:

Just looking at all the information. Obvs I am not doing the work, but the mechanic did mention about the pinion nut. The repair you mention, is that some thing you can tell me more about please in case we need it?
I'm going to call Overdrive too. Bernie recommended them as well. Think they supplied or refurbed the overdrive.

As Glady is an early 70's van it's considered to be a later PB so the larger bore brake master cylinder is the one to go for. Also if you ever need front wheel cylinders again it's the large bore type.

Thank you.
Now hit an issue with the gear box. Spoke to James at OverDrive - very helpful, sent him the photo above and he says:
The overdrive you have is a D Type overdrive with a sliding yoke prop fitment at the rear
I can supply the rear seal for you.
So ...the good news is that he has the seal, but if the overdrive is a D type does that mean the gearbox is too??
Sorry to be a pain.

Not painful at all we're only to happy to help where we can that's what this forum is all about so please don't hesitate to ask anything:)

Basically the overdrive is an add on bolted to the end of a normal four speed gearbox which gives you a 5th gear so don't worry about that side of things. I may have confused the issue by talking about gearbox seals but in fact the only seal you need is the one suggested by OverDrive.

The pinion seal is another thing entirely as it fits into the back axle.

Ok that makes sense but does the J or D gearbox affect the Clutch Slave Cylinder or Clutch Master Cylinder? ie are they different for each type? I just don't want to order the wrong parts. Once I know which gear box i will order those two plus maybe the Brake master cylinder from the same place and then the rocker gasket from Speedy Spares.
Colin the Fox gave me the info for the pinion seal and I've ordered that one.
So I am making progress.
Thanks so much.
 
Wouldn't bother spending money on that rust bucket. I will take her off your hands, saves you the trouble lol.

Thank you that was brilliant advice and I have ordered the seal from Simply bearings with the dimensions in the link! Huge help! I also spoke to OverDrive and he says the overdrive is a D? and thinks he has the seal, so will sort that on Monday. :)

In this link, https://forum.commervanfan.co.uk/threads/jennings-restoration.7437/page-16#post-146407 the 3rd pic is of the repair sleeve slipped over some wet epoxy resin on the drive flange. It's only a very thin stainless sleeve and you use the same size oil seal. You only need a sleeve if there is a wear groove in the drive flange, or maybe surface rust which prevents the seal sealing. I got mine from Simply Bearings. It's described as "99162 Hardened Stainless Sturdi Sleeve for Shafts 1.622-1.628 inch". It cost less than £15 in 2017, and hasn't dropped a single drip of oil since then :) .
